u/solovus · 4 pointsr/homechemistry

>[E]very chem lab should have a good number of 150-250 mL glass beakers on hand.

  1. After looking up the differences (incl. price) between regular glass and borosilicate glass, when would borosilicate be mandatory?

    >Some large size glass test tubes will come in handy, and those are relatively cheap.

  2. What would be considered "large size?"

    >Depending on what type of reactions you want to do, you may find it good to have petri dishes handy, either glass or plastic (they'd be good for crystallization experiments, certainly).

  3. How many, and of what size, would be good for starting?

    >You should definitely have a few pipettes, either the cheap plastic 3 mL kind, or if you can afford it, nicer glass droppers (Pasteur pipettes are fun to use, albeit fragile and hard to clean).

  4. Are the glass pipettes for strong acids, basis, or organic solvents? Are there any other benefits to glass pipettes?

    >You will definitely need a graduated cylinder, maybe a few, in different sizes, glass or plastic (definitely glass if you're planning on working with any strong acids or bases, or using organic solvents).

  5. What sizes should I be looking for? I'm guessing polypropelyne is the preferred plastic type since that has the most available on Amazon. Is this Set of 7 Polypropylene Cylinders sufficient? What size glass cylinder would be the most common for home experiments with strong acids, bases, or organic solvents?

    >You will find a scale, accurate to at least a tenth of a gram, to be an invaluable tool.

  6. Could you please recommend a specific scale, or at least a type? I'd like to spend as little as possible without getting a piece of junk. Is there anything available for under $100?

    >Some litmus or pH paper will be useful.

  7. Most of these seem to be range limited. I found what appears to be a full range paper or a set of papers that provide full range. Would you recommend either of these?

    >Oh, and a thermometer, of course!

  8. I thought this one was simple until I looked it up. What exactly am I looking for here? Infrared Thermometers seem like a good idea because they don't physically contact the sample, but I'd like some guidance with regard to a trusted brand.

    >If you want to dispense precise quantities of any liquid, a 25 mL burette will be your best friend, though it's certainly not necessary.

    8.a) This one seems relatively straightforward. Finally!

    >a volumetric flask, for making precise stock solutions.

  9. Size? I've tentatively added a 100ml and 500ml to my list. Is Karter Scientific considered good quality?

    >A few Erlenmeyer flasks, for mixing things.

  10. This set of Erlenmeyer flasks seems like a good place to start. Which sizes do you find yourself needing most often?

    >A volumetric pipette, for making equal aliquots.

  11. Wow, these things appear to be quite expensive. What types of home experiments would it be difficult to do without a volumetric pipette? This one will probably wait until the need arises.

    >Oh, and if you just want your lab to be that much more mad sciencey, you could have a distillation flask and a few condensation tubes bubbling in the background. If you want to make a significant investment, you could get a magnetic stirring platform, maybe one with good heating powers. Also great for whisking up an egg, or keeping some batter moving while you make pancakes. Pricey, though.

  12. I'll probably stay away from the distillation flasks and condensation tubes until I stumble upon an experiment that requires them, but the magnetic stirring platform looks like a much cooler way to make coffee in the morning. Is this stirrer from Hanna Instruments any good?


    Thanks a ton for putting together that list!

u/chrisgilbertcreative · 1 pointr/vaporents

Ultrasonic cleaner. Water in the reservoir. Disassemble cooling unit, detach O-rings and set aside. Put disassembled parts into a portion control zip-loc bag with iso. Zip bag, toss into the water, and depending on your USC, mine does a 90 second option. I run that once, check on it, and run it again if necessary— but it hasn’t been yet. The zip-loc bag helps conserve iso, and also lets you do a few batches at once. I typically run a bag full of ELBs from my EVO, mighty cooling unit, and stems from my solo 2 in three separate baggies. Cleaner works a charm on my orbiter and countless GonG adapters, too. Then just rinse everything in water (or do a run in the usc with just water). Paid like $70 for the thing on amazon and it’s already paid for itself. Another poster below said something to the effect of “if cleaning is easy, you do it more routinely.” This is true. My last thought? I look at it like a $70 new vape, because it basically resets all your vapes and glass to factory fresh. For example, I had no concept for how much difference brand new ELBs make on the EVO. I now clean them weekly. Takes less than 5 minutes!

Edit: price was slightly off, and to add a link. THIS is the ultrasonic cleaner I use. but there are many cheaper options out there that probably do the same job. I just don’t have a ton of space in my apartment, and it blends in with our other kitchen Gizmos, so for those reasons it was worth the premium.

u/xx2000xx · 1 pointr/DMT

If you're going to vape like he suggested here's what to get.

For VG/PG this is food grade and what everybody uses: https://www.amazon.com/Glycerin-Vegetable-Kosher-USP-Quart/dp/B004C7MTLA/

Here's the scale everybody uses which goes down to .01 grams and is flawless: https://www.amazon.com/gp/product/B005UGBG20

Sign up for http://e-liquid-recipes.com/ and then you can use the calculator to measure with grams and break down the pg/vg nic and flavors which is the tool all DIY e-juice use. Back in the day we did it by volume which was a pain in the ass and doing it by grams is a game changer.

I wouldn't bother with nic but if you do choose so nudenicotine.com offer a free sample ($3 shipping) get the 100mg pg version. If you do go into ecigs DIY section for safety. Although if you have common sense it's actually very easy and safe but go to the right section in DIY.

Get pippets: https://www.amazon.com/Teenitor-Plastic-Transfer-Pipettes-Dropper/dp/B01G82SJRY/

Get some latex gloves or something.

If you're going to add flavoring this is my favorite: http://www.bullcityflavors.com/natural-mint-wg-inw/ - or their mixed mint which is the same but menthol - Eucalyptus will clear your sinus for a year.

INW is a premium flavoring company because $2-3 dollars for flavoring is expenisve in the juice world, that's why every vapor should DIY but they get overwhelmed with all the info, but it's easy as hell. The 10ml (don't bet the 30) will last you probably your whole life. I would go either 1% or 2% using the calulator, I couldn't imagine using anything above 3% because it's so crazy concontrated.

u/saroka · 1 pointr/Random_Acts_Of_Amazon
  1. Totally tea(Main) for this one! Or actually, wait, an umbrella(Main) is probably more fitting for England. XD

  2. Oh god, I couldn't imagine walking around like Harley Quinn!(Hobbies)

  3. Most phallic... hm... this giraffe(Home) looks pretty phallic to me. XD

  4. Oh I got this one totally covered! Beaker shotglasses!!!!!(Other)

  5. I really want to learn how to sew so a sewing machine(Expensive) and a dressmaking(Main) book are where I'm going to start.

  6. This magical shady umbrella(Expensive) thingy will keep you from burning up!
u/falconPancho · 4 pointsr/AskEngineers

Wow that is a ludicrous price. Most of us could flatulate a better design. Based on what I see immediately in front of me I would use two of these mk2 3d printer bed plates. Put them in series. https://www.amazon.com/dp/B01HPXA8EC/ref=cm_sw_r_cp_apa_O.vjybW7MW53F then I'd take my shittest power supply set it to 24V and maybe some constant current at 500mA to 1A and see how hit it gets under the aluminum. https://www.amazon.com/dp/B00O8DJ8QC/ref=cm_sw_r_cp_apa_ndwjyb2N27R1A

Best part you dont need a controller cause even that silly $1000 device is only giving you a adjustment pot. Then if your wife changes her mind you can start building a 3D printer.

Go to harbor freight and treat yourself to one of those laser aim non contact thermometers too. You'll marvel at how much money you saved and how even the heat is.

u/ithinarine · 5 pointsr/minipainting

Definitely a little more expensive, but I highly recommend people try out a vortex mixer. They were originally made for lab work to easily and quietly mix liquids, you just push what ever you want on to the rubber top and it vibrates. I know several tattoo artists and laquerists who use them, and I ended up buying one for my paints. Absolutely amazing.

u/childishidealism · 1 pointr/Homebrewing

Sure. As has been typical for everything I've built for brewing, I went through several iterations starting with an idea very cool and complex, but ending with something super simple. In the end all I have is a 9V charger with the end cut off and connected to a pc fan, with magnets glued on it, inside a cigar box. The combination of voltage and fan speed works out just right. I tried setting up a pulse width modulation circuit, then just a potentiometer and none of it worked as well as the final simple setup. Which is quite embarrassing with my EE degree.

Anyway, I do have a few pieces of advice. Glue the magnets onto a washer or piece of something first, spaced out to match your stir bar, then glue that whole thing to the top of the fan. Otherwise, the magnets want to move on the fan and are hard to glue down. Get more magnets than you think you'll need. I used this stirbar and these magnets. I bought the cigar box from a cigar store for $2. Everything else I had sitting around.


Search DIY stir plate on google and you can find tons of how-to's.

u/Umlautica · 1 pointr/audiophile

You might ask /r/audiorepair to see if anyone has a lead on a schematic. Make sure the output relay is clicking and try using the front/rear channels as well. In cases like this it helps to have an oscilliscope to probe the signal as it goes through the amp and see where it stops. I have a $85 DSO Nano V3 specifically for this and the fact that it's battery powered helps keep things safe since there is no path to ground.

Cool, those ESS have Heil AMTs. Sounds like a good project.

u/reggie_cleveland · 3 pointsr/Vasectomy

It's pretty easy to find testing kits on Amazon, but from what I've seen those cost $25-$45 each and only tell you in an analog fashion that your sperm count is above or below 20 million.

My recommendation (the rest of this is just a repost of something I posted earlier this week--sorry to anyone that's seen this before):
If you're looking for a long term solution that requires some investment but could really ease your mind...

You could buy

-A Microscope

-Some slides

-And some pipettes

...and then check your sperm count once or twice a year. All that costs about $100, but it should last you decades. I won't have my vasectomy until a couple weeks from now, but I've purchased these items and looked at my sperm under the microscope in order to get a feel for it.

Count the sperm in the 400x field of view. Record the numbers on the analysis sheet, or multiply the number by .5 to see the total. The total number of sperm is counted in millions, so a result of 72 would mean approximately 72,000,000 sperm.

According to the World Health Organisation, a man needs a sperm count of at least 20 million sperm per millilitre of ejaculate to have a chance of conceiving a child without medical intervention.

u/SugaRush · 1 pointr/minipainting

My friend, let me introduce you to the Vortex Mixer. As Coyotebd said, it does the job super well, no matter what paint you are using. It is seconds and its mixed. Personally for me, Vallejo has been the hardest for me to mix up, some times the colors separate a little and its hard to get them all mixed up again. The mixer took care of that in seconds. Get one if all you have is dropper bottles, but it works well with GW also, but make sure the lid is nice and tight.

u/GrowMender · 6 pointsr/microgrowery

WA state medical patient with RA and wanting to do a real grow for almost a decade. Helped a few friends with their grows and trim sessions over the years and also attempted a few outdoor hidden grows with little success (bad weather, theft, pests/animals). Finally decided to save up and do it properly now that I have space indoors. I have been lurking /r/microgrowery for over a year now and have learned a lot and want to thank you all for everything you do. I also want to thank the YouTubers Growing With Mr.Tight, JustinTime2Grow, and medgrower1 for also being excellent resources. Now onto the details:

 

    Equipment

Gorilla Grow Tent 4x4

2x 600w MH / HPS lights for a total of 1200w. 75w per sq. ft.

400 CPM 6in In-Line Fan

Phresh Filter 400 CFM

Hygrometer

TDS Meter

Infrared Thermometer

Grow Room Glasses

 

    Plants

Blue Dream - DJ Short x Santa Cruz Haze. 80% Sativa / 20% Indica. 7-8 week flower cycle

Boy Scout Cookies - Girl Scout Cookies Thin Mint x Pre-98 Bubba Kush. 60% Indica / 40% Sativa. 8 week flower cycle.

Darth Vader Haze - 4-way Black Haze Black Cross. 100% Sativa. 9-10 week flower cycle.

Grand Daddy Purple - Big Bud x Purple Urkle. Indicia Dominant. 8-9 week flower cycle.

 

    Grow Medium and Feed

5 gal Smart Pots

Fox Farm Ocean Forest Soil

Fox Farm Trio

18-6 Lighting cycle for veg. full 1200w of MH.

Using tap water and PH Down (is around 8.0 right out of the tap). I let the water sit for at least a few hours to let any chemicals leech out into the air and bring it closer to room temp.

 

The GDP went in almost a full day later. It was a younger clone and I was worried about the transplanting shocking it, but turned out fine. One of my MH bulbs had bits of broken glass in the outer part and didn't work so I had to wait on a replacement arrived on day 6. Also I ordered the wrong size Phresh filter and am waiting for the refund to process so I can get the right size. Temps have been hovering around 80F ambient with the lights on and 40% RH.
Temp minimum during dark cycle is 68-70F and humidity maxed out around 85% RH.

First watering with nutrients will be as soon as the soil dries a bit more (still damp at knuckle deep). Will be doing a half strength of the Big Bloom for the first feed likely tomorrow morning an hour or so after the lights kick on.

I eventually want to get an 8x4 to use as a flower tent and have the 4x4 as a veg tent to set up a perpetual grow. I am also seriously looking at the GrowBlu lights for veg when I do this, the results I am seeing from the guys on YouTube using them just looks amazing. I also want to switch over to en Ebb and Flow type system instead of soil when I do that, but that is something I need to look into much more.

u/Swimmingbird3 · 1 pointr/hydro

Generally you should follow the instructions on the fertilizer as instructed, if there are any. Then test your water with a TDS meter to ensure you have acheived the right concentration. I use this one.

Hopefully you picked a water soluble fertilizer, preferably one meant for hydroponics. I have heard of getting by with other fertilizers such as miracle-gro but this kind seems like a hack job to me personally. General Hydroponics make some cheap and effective hydro concentrates that are a good place for beginners

u/Kevin_Wolf · 1 pointr/ReefTank

I use this. It works very well, and it's at the very least a name brand. You can add in a DI can if you need to for not very much money, if you don't get 0 ppm. I get 0 ppm every time, and we have 400 ppm source water from the tap. If you want to test, this is only $20, and it's great. Best shit you can get, without regard to the price. For home use, it's awesome.

The 50 gallon version makes it fast enough.

u/Justin429 · 2 pointsr/DIY_eJuice

I recently sent a pretty big email list to my brother, so I'm just copy/pasting out of the email. Before you ask why I'm recommending 12 packs of the beakers, it's because they break, and you WILL break them. Buy this stuff:


Scilogex 86143101 Model MS-H280-Pro LED Circular-Top Digital Magnetic Hot Plate Stirrer with 5.3" Diameter Ceramic Coated Plate, 110V
http://amzn.com/B00AYGIFCA - I'm not sure why, but when you use this link, it takes you to a non-amazon supplier. Click the link to buy from other sellers that offer prime shipping. It's $60 cheaper.


Spinpak Magnetic Stir Bar Assortment with Pivot Ring (Pack of 6)
http://amzn.com/B002VBW72K


Glass Beakers, 50ml Pack of 12
http://amzn.com/B003K1EH0A


Glass Beakers, 100ml Pack of 12
http://amzn.com/B003K1KQKK


Edit: Also, I don't turn the heater on until I've finished adding all ingredients except nicotine, but the entire time, I'm running the stirrer. Once all ingredients excluding nicotine are in, I then set the hotplate to 80c, and run the mix for 90 minutes. If you have beakers that have a cap, use the cap to capture vapor instead of letting it escape in to the atmosphere. If you buy the beakers I linked, you'll need to cover them. I use plastic wrap with a very small rubber band (like for orthodontic braces.)

Edit 2: Before heat is applied, I'm stirring at 200 rpm. Once the solution is up to temperature, I increase to between 450 - 700 rpm depending on the viscosity of the liquid I've created. You'll have to play around with the speed until you arrive at a speed that is not causing the liquid to spin out to the sides so much that the magnetic pill is halfway out of the solution.

Edit 3: I have sacrificial magnetic pills in each of my bottles of nicotine. When I take them out of the freezer, they go directly on the stirrer. NO HEAT. Just leave the cap on and stir for a while.

Edit 4: Before you balk at the $200 price tag of the stirrer, consider this. My ADV is POET Amaretto Nite Cap. It's $22 a bottle. I go through a bottle in a little less than 3 days. This stirrer costs the same as 9 bottles. A bottle of DIY juice costs approximately $1 to make. Do the math.

u/UndeniablyRexer · 2 pointsr/ECEComponentExchange

Are you in college? Or is there a nearby college you can make friends with? This is the sort of equipment they should absolutely have on hand.

If you're able to transport yourself, this may be a great place to look: https://www.electronicsfleamarket.com/schedule

Otherwise, I've no experience with these, but you might check out standalone units like this: https://www.amazon.com/Handheld-Oscilloscopes-DSO-Nano-V3/dp/B015X6LZFO

There's also stuff like this where you might be able to get more bang for your buck if you're able to supply a computer: https://www.electronicproducts.com/Test_and_Measurement/Benchtop_Rack_Mountable/Top_7_PC_based_USB_oscilloscopes_of_2017_for_hobbyists_makers_and_pros.aspx

u/ClosetCaseGrowSpace · 7 pointsr/CannabisExtracts

Hello, r/CannabisExtracts! Visitor from r/microgrowery here. I'm wondering if you experts can help me dial in my blasting technique. Here's what I did:

  1. Grew a pound of weed.
  2. Dried it.
  3. Cured it in jars for two weeks.
  4. Broke up 56g of mids into pea-sized pieces.
  5. Stuffed weed into this Ablaze 90g closed column blast tube.
  6. Put filled blast tube in the freezer for two hours along with 4 cans of 11x butane.
  7. Evacuated my blast tube.
  8. Filled my tube with butane and waited 5 minutes.
  9. Blasted outdoors into a Pyrex dish using 4 cans of 11x butane.
  10. Let the butane boil off outdoors for 90 minutes on a heating pad set at 120 degrees.
  11. Scraped resulting goo onto Ablaze silicon mat.
  12. Placed in this Ablaze vacuum chamber for 20 hours.
  13. Peeled resulting goo from silicon mat to get 4.83g of this.

    How did I do? I haven't tried it yet, but it smells pretty strongly of chlorophyll. I'm afraid that this will be suitable for making edibles, but not so good for dabbing. Please give me your constructive criticism. Thanks, fam!
u/OpiumPhrogg · 3 pointsr/electronic_cigarette

Scale. You need a scale to be accurate when mixing. A scale and some pipettes have been doing me just fine. I also have 3 clear squeeze bottles that I fill with PG/VG/NIC from my larger containers.

It's so fast to mix juice now, clean up is a breeze. I love it.

The scale I use

3ml Pipettes

While I don't recommend bottom of the barrel, You hit the "monster-cable-better-digital-signal-quality" snake oil pretty quick in the PSU market.

Unless your overclocking and need super stable power at razor thin margins. Consumer gear can easily handle anything that's properly in spec.

More than about 100 bucks though and you could buy an actual Bench power supply

OK. The tank I bought for $89 bucks and I put some Mean Green cleaner to run in it. https://www.amazon.com/gp/product/B075FTFD3R

As for the Curing box, I have a lasercutter so, I used the awesome https://www.festi.info/boxes.py/ website and designed a two part slide box. I made some mods in Inkscape to accommodate my light.

I lined the box with this lasercut plastic mirror: https://www.amazon.com/gp/product/B075M7VGVM

If it's mostly for personal use and you might upgrade in the future to something bigger like a full oven vac ($1000-$3000+). Then it might be worth considering something cheaper
https://www.amazon.com/ABLAZE-Gallon-Stainless-Degassing-Chamber/dp/B071KZXVRR/

Could then save for a bigger system and still get at least a few good runs out of something cheaper. BVV are overpriced in my opinion

u/MacTheBartender · 5 pointsr/AskElectronics

After a lot of looking around I picked up a Korad KA3005D for ~$120USD and free shipping.

Will supply up to 5A at 30VDC; reviews all say it regulates the power well, doesn't have any crazy overshoot when turning off/on, little voltage ripple; comes with leads; and has a separate output on/off toggle so you don't need to disconnect the leads to adjust power or anything; over-current protection; digital display so you can enter your values with precision.

Probably a reason it's one of half a dozen models listed as recommended on the wiki.

u/Rob27shred · 1 pointr/MechanicalKeyboards

Mines pretty old so I've been looking at getting a new one & this one is big enough to hold a decent amount of switches, has good reviews, & is decently priced. Although Amazon has plenty of them & if you do not see yourself using it much in the future I'd go for a cheaper one. Just make sure it's not a really small one if you go the cheap route.

Works great. I would be curious to know if the "get what you pay for" reviews are from user error and not product quality. I routinely make 4l starters with this and I never have to go above half speed to get a good whirlpool. Its all about matching speed with the correct size stir bar. A larger bar in a larger volume at a slower speed seems to work better than a small bar at high speed.

Found a nice mini magnetic stirrer on amazon for ~$85. Would be a super nice convenience but I'll continue to live without cause I'm a cheap SoB.

I should mention that I'm old school despite being new though too. No ultra sonic or even a frother. I just give em a good shake and let them cure over time (sometimes I'll do a hot water bath but have been even too lazy to do that lately). Then again, that's what happens when your closet looks like this (ready to vape juices) and if you ever want more flavors. Yes my caps are off at the moment, happens once a week for a day.

  1. It's your money, do what you want.

  2. The downside of lower-price digital scopes is tiny memory storage depth, lower bandwidth, and lack of serial bus decoding. If you are working with any microcontrollers, then at some point you'll wish you had the ability to decode data on various serial buses, and yes it's worth the extra money to get it. I recommend that you look at other scopes that have serial bus decoding features. I found the following while looking at the Siglent website.

    $379 SDS1202X-E includes bus decoding for I2C, SPI, UART/RS232, CAN, LIN buses.

  3. Users say the SDS1202X-E had some capacitors missing on models without "BB" in serial number, so ask before buying to ensure you get the fixed model. Look at comments at Amazon link below.

u/RapeApe · 1 pointr/todayilearned

I used to have an under-sink charcoal filter system (basically like a brita, but it comes out of a faucet) that cost around $50-90 to replace every 6 months to 1 year...one time I was looking on amazon to replace my filter and I discovered that an RO filter system was not that expensive...

For $190 (around the cost of 2-3 replacement charcoal filters) I got an RO system that makes very tasty water...much better than the charcoal filter... and I haven't had to replace any of the filters in the system yet after about 3.5 years.

I'm using a TDS tester, still getting around 10 ppm...comparable to most bottled water that I've tested (my normal tap water is about 180 ppm).

Also, the replacement filters are much cheaper than the charcoal system.

This one. But I can't justify the cost right now. The other one I was considering is this unheated one. It's a lot cheaper, but I have a feeling that I would regret it when I buy the other one anyway. And with high VG mixes, I'm not sure if the stir bar can mix it cold well enough (or if it's that effective to continuously stir when cold).

I'm still very green in all of this, hence my reluctance to plunk down cash on something like this at the moment. Right now I use a Thermos filled with hot water and I shake that every 30 minutes or so.

u/SuperAngryGuy · 2 pointsr/arduino

The data stream is going to be a few kilohertz at most with these cheap 443 MHz units so that low cost USB scope will work. You only need to tap on to the data output of the 443 MHz receiver to read the data being sent.

You'll have to do manual decoding which is not hard at all. There are protocol analyzers built in to oscilloscopes, though. There is something to be said for a desktop scope particularly if it's your main scope. The "color temperature display and 256-intensity grading" feature is extremely valuable.

https://www.amazon.com/Siglent-Technologies-SDS1202X-Oscilloscope-Channels/dp/B06XZML6RD/ref=sr_1_fkmr0_1?keywords=Siglent+SDS1104X-E+100Mhz+digital+oscilloscope+2+channels+standard+decoder&qid=1567190698&s=industrial&sr=1-1-fkmr0

To directly sample a 433 MHz signal you'd need a 5 GHz or so oscilloscope which is many thousands of dollars. You pay for speed.

edit- with on-off keying you can put something like this with a wire antenna next to the transmitter and just read the output with any scope. I can also pick up some data streams from my cell phone with this although it's not on-off keying.

It probably depends on your drill I guess. I only have one and it's a fairly high-end consumer / low-end contractor's drill. Your standard Stanley might not have a large enough chuck to fit. All you really need is to be able to get a tight enough fit so it doesn't immediately fall out. Eventually it will become out of balanced and fly out, but that's inevitable. You'll also scratch up the surface of the cap so only do it if you don't care. I actually just bought a vortex mixer from Amazon. I've seen it between $65 and 75$, which is a lot cheaper than the typical $350. It works really well for hobby paints. https://www.amazon.com/LabGenius-MI0101001-Mini-Vortex-Mixer-Clear/dp/B01CLLBZ6S/

We bought a water testing kit when we moved in (this one for the curious) and tested our tap water over concerns about lead, once everything came up fine (on the test ran twice, a week apart) we drink tap water sometimes now and use it for cooking.

u/outofvogue · 2 pointsr/Eugene

You can also buy a water testing kit if you want. It's overkill to send it to a lab right away. You should do the kit first to see if it tests positive for lead, if it does then send the water out to a lab to see how much is in your water.

u/cosmicosmo4 · 1 pointr/AskElectronics

You just want a controllable constant-current-constant-voltage power supply. Buy this.

Your solenoids, like all DC loads, have some Current vs Voltage curve, that they have to obey. For the simplest load possible, a 1-ohm resistor, that curve is Current = Voltage / 1 Ohm. Solenoids might have a nonlinear curve. But they simply can't operate off of the curve. All you get to do, as the operator, is choose where on the curve to be. You can apply whatever voltage you want, and the curve will dictate what current flows. Or you can choose what current you want, and apply the voltage that gives you that current. The device that you need to do both of those things is a constant-current-constant-voltage power supply.

What you've been told ("the voltage needs to remain at the same level whereas changing the amps with move the spool") is probably just a simplification of the fact that the current-voltage curve in the region of interest has a very high slope - so only tiny changes in voltage are needed to produce large changes in current. Or, put another way, the desired change in current will only require a tiny voltage change. Or they were just wrong, and misunderstand it themselves.

The home version is to raise the temps to between 75-80c and sustain it there, while mixing, for an extended period of time, and allowing it to cool to near room temp before bottling.

Stuff you'll need (Prime links given)

$200 digital hotplate: amzn.com/B00AYGIFCA

$13.50 large flask: amzn.com/B00BERGESK

$9 rubber stopper to fit flask: amzn.com/B00ES3UE9C (can be had for $.50 at Fred Meyers or lab stores)

$17.49 for a hose to run from faucet to condenser: amzn.com/B000KI7VN6

$16.72 for the condenser: amzn.com/1450567898

$13.03 for a stand to hold the condenser: amzn.com/B00657N7TS

Misc you likely already have around:

Large pot or dish that can hold the flask

Cleaning sponge or rag

1/2 gallon vegetable oil

Total cost: $269.74 and maybe $20 for the misc stuff if you lack it

Preparation: This needs to be done in a temperature controlled room; the method uses slight variations in temperature to isolate out the individual chemicals, so any fluctuation in the room will hinder this. You will need to be near a sink with a running faucet. Be prepared for this method to take 24 plus hours.

Method:

  1. Place your large pot on top of the hot plate, and place your sponge or rag in the center of the pot. This will prevent a hot spot where the flask touches the pan.

  2. Fill your flask with the herb or extract you will be isolating (use extract, the results are much purer!), and place it on the sponge in the pot. Stopper the flask.

  3. Attach a hose from the stopper to the top of the condenser. Attach a hose from the faucet to the coolant intake on the condenser. Attach a hose from the coolant exhaust and let it dangle in your sink.

  4. Fill the pan with 1-2 inches of oil. Not enough for the flask to float, but enough for the oil level to be above the level of your herb or extract in the flask.

  5. Start running cold water through the condenser, and start heating the oil. To get a list of the required temps, lookup each cannabinoid on Chemblink (or wikipedia), and look for the evaporation temp listed. Start with the lowest temp and work your way up.

  6. Once the oil has reached the temp you specified, let the system run for at least 4 hours. You will begin to see resin buildup inside of the condenser. This is your isolate. Once you are satisfied that no more isolate is building up: run hot water through the condenser so the isolate melts and runs out of the condenser.

  7. Go up a heat level and repeat 5-6.

    As I said, this really only works for THC-like cannabinoids, you won't get any terps with this method without much more expensive equipment (theyll just evaporate away), and the overall loss is great enough that its unlikely youll be able to get an isolate of CBG or THCV, since they are such a small percentage of the cannabinoids, but you should have no problem getting pure THC and even CBD, assuming your starter strain has more than a percent of it. Once you have isolates you can isomerize and do other fun stuff as well.

    That said, pure THC isnt fun at all, but its a great learning experience, and you can also use the same setup to distill essential oils or liquor, which is a slightly different process but uses the same equipment (though you can sub the digital hotplate for a cheaper electric range for those purposes)

Gesswein is Canadian, as is Caswell.

Not knowing where you are, I suggest you searching for a jeweller's supply shop.

In Vancouver there is Lacy West.

I'm pretty sure Rio Grande and/or Ottofrei will ship those chemicals to Canada.

Edited to add, I purchased this power supply from Amazon.com with no problems.

I believe that a heated plate is essential in the speed steeping process (which I assume is what you're going for) in which case I doubt you're going to find one under $100. I believe this one is the go-to for most people here. There are some "lightly used" ones on amazon as well for a few bucks cheaper.

Pipettes usually are really slender and long and used for the same purposes.

One of these. Although I only paid $75 for mine.

Either buy the carbonation tablets or use these: https://www.amazon.com/gp/product/B00P7QZDK4/

3/4 cup of simple syrup divvied up 50 ways is about 3 mL.

This is the slides I have been using. Could these be causing the issue?

Northern Brewer is having a sale on their stir plate. Personally, I own this one. I love it and use it all the time when making starters.

Here's some options, they are all basically the same:

  • Simple dishwashing detergent, without fragrance, like Ivory
  • Baby shampoo (if you don't mind a bit of leftover scent)
  • 1:4 mixture of vinegar:water

    Soak the equipment for 10 minutes or use an ultrasonic cleaner if you want to be extra thorough.

It all depends on what speeds you need. I regularly look at signals between 100MHz and 200MHz, so I recently bought https://www.amazon.com/gp/product/B06XZML6RD/ which is the cheapest I could find a 200 MHz scope. It's also seems to be the breakpoint for scope bandwidth on a budget - anything faster was over $1000 instead of ~$400.

Logic analyzers make more sense for digital work... but if your problem can be solved with a logic analyzer you can usually use the internal one (Each FPGA brand has something that works similarly: Chipscope, SignalTap, Reveal).

I only pull out a scope when I'm worried about analog fuckery like contention/ringing/rise time issues.

I believe it's this one: https://www.amazon.com/LabGenius-Mini-Vortex-Mixer/dp/B01CLLBZ6S?th=1

I had heard about vortex mixers for test tubes, and asked my doctor in law if she could find some cheaper than what I was seeing. Just unwrapped this from her, and I swear, I wasn't fishing for gifts!

This is not a recommendation, just some examples of what exists on the low end for bench supplies (off-the-shelf in the US):

KORAD KD3005D Precision Variable Adjustable 30V, 5A DC Linear Power Supply

That's a single output channel for $85.

I have something very similar to Triple Linear Variable DC Power Supply, Adjustable 30V/5A. There are many lookalikes. That's two adjustable channels, plus a fixed 5V (which I never use) for $180.

When working with a cheap supply, I:

  • don't leave it on unattended or overnight
  • always disconnect the load before turning the power switch on or off.

I’ve been using mineral oil on any knives that might cut food and gun oil on others for a long time. I got some of these some time back to use with mineral oil and also for alcohol when I’m cleaning. They work really well.
