Reddit mentions of Cylewet 25Pcs 12x12x7.3mm Momentary Tact Tactile Push Button Switch Touch Switch Micro Switch 4 Pins SMD PCB with Cap for Arduino (Pack of 25) CYT1009

A few weeks ago I posted some pics of a "quick and dirty" induction heater I made:

https://www.reddit.com/r/vaporents/comments/8igobf/gear_shot_yet_another_quick_and_dirty_dynavap/

The heater I built in the previous post worked great, but I wasn't happy that it heated continuously when it was powered on. I decided to add an "on demand" mode, similar to the way the Portside functions: I wanted the induction heater to be energized only when the vapcap was in need of being heated.

I decided to use the same method and hardware that the Portside uses for its triggering mechanism: a small momentary switch at the base of the coil, utilizing the same 12 mm x 12 mm Arduino 'tactile' input switch as the Portside. This switch is normally open but closes (and activates the circuit) when the vapcap is inserted in the induction heater opening and lightly pressed down. I mounted this to a 25 mm square Zip tie "sticky base" using a small dab of hot glue, and ran the wires under the base through a drilled hole. I am happy with how it came out.

I took one other feature from the Portside design and decided to use a MOS FET triggering module to handle the actual power switching, sparing my momentary switch from having to pass enough current to power the heater.

This is the finished desktop unit - pictures, diagrams and some other notes:

My original 'big red switch' was a pull from an Epiphone Valve Junior guitar amplifier, left over from an earlier project. It looks nice, but it's nothing special - any latching (i.e., non-momentary) single pole/single throw (SPST) switch will do. This site has some switches that look pretty good and could work:

Like the Portside's trigger, I used a 12mm x 12mm Arduino tactile (momentary) switch. Mine is hot-glued to a Zip tie "sticky base", which has the foam removed and is screwed to my board. I kept the stock Arduino switch button and trimmed its edge to fit inside the tube. There is a small segment of 7/16" wooden dowel inside the tube to achieve the correct height.

If you plan on using a momentary switch, this is the way to go. Don't make the momentary switch directly supply the heater current.

I know many of you have these for yourselves and don't need any help or parts lists, but this may help those who need a little more guidance.

Updated to add: the above links are intended to show the correct parts, but may not be the cheapest or fewest quantities available.

​

in addition, you'll need some 18-20ga wire & solder, and a 12v/6a to 10a power supply

Awesome man. I cannot tell you how cool I find all this. Science!

Here is what I have purchased so far.

12v 6a 72w power supply

ZVS Heater and Coil Combo

Switch. Can hold up to 20amps not sure that mattters whatever, room for extra isn't bad.

[Glass Tube]I DELETED THIS AS WHAT I HAD HERE IS TOO BIG! DO NOT BUY THE GUITAR SLIDE I HAD LISTED! NEW TUBE. I ordered this from China on a Thursday, let's see how long it takes to get here.

So, I would just be missing the mosfet and momentary switches that you have. Do you find them necessary? I might just buy the mosfet and momentary for peace of mind, but I did see a couple build that avoided the mosfet for simplicity's sake. This build seems to have avoided one.

Any further advice (wire gauge, soldering tips, etc)? I am currently looking for a good box to put it all in. Thanks again for the reply.

EDIT - MOSFET

Momentary Buttons

Mounting things for the momentary buttons

IF ANYONE IS READING THIS IN THE FUTURE, CONSIDER USING A 120W POWER SUPPLY. I DO NOT REALLY UNDERSTAND BUT SUPPOSEDLY IT MATTERS.
