Reddit mentions: The best dog whistles

I would suggest going for a working dog - collie, springer spaniel, german shepherd, lab etc if you're very active. They can drive you up the wall if they don't get out much OR their brains aren't challenged regularly. You need to keep in mind what that working breed has been trained to do over the centuries, herd, guard, sniff out stuff etc and train/walk them with that in mind. If you have a springer spaniel and try training it whilst there are critters around in the undergrowth you'll have problems. Border Collies are sight dogs so again, you're going to set the dog up to fail if you try and train them somewhere sheep or similar are about.

The trendy breeds I'd advise against such as mentioned elsewhere bulldogs and pugs as their breathing is awful due to their shite selective breeding/eugenics.

I was told about a way of training recall by a hunting dog trainer. He said buy one of these 210.5 dog whistles.

When the puppy is young and ready to go on walks off lead then you whistle three times and place the puppies food down as it arrives to investigate. The following day do the same thing. Then on the third day take the food out to the park with the puppy when it's run off to investigate something blow three times again and give it the food when it arrives. That... surprisingly was all it took to train mine to recall to the whistle. This is what you use in emergencies and need the animal to return immediately.

For general training you need a [Clicker](

Positive reinforcement works great. Take a read of these and take small steps and you'll have a fantastic dog whatever breed you choose.

Good luck.

You're not wrong but you could be nicer about it.

OP, be very careful with those relays. Don't leave whatever circuit you are making unattended, or consider using something safer like this: https://www.amazon.com/POWERSWITCHTAIL-COM-PowerSwitch-Tail-II/dp/B00B888VHM/ref=sr_1_1?ie=UTF8&qid=1479919667&sr=8-1&keywords=power+switch+tail#customerReviews

$3.21 is the closest I can get :P Thanks for the contest! Welcome and happy early birthday!!!<3

In my expert dog opinion whistles are best for dogs with dodgy recall. They tune out from human voices it seems, but a whistle gets their attention. We use this one

Start in an enclosed space, 2 short sharp toots when he comes back give him a treat. Practice outdoors in quite areas always give a treat then he'll associate the whistle with a treat. Depends if he's food driven though, some aren't as greedy as ours 😂. Takes a bit of practice. Ours stops dead in her tracks now when whistled 🎇

I moved shops recently and wanted to have piped dust collection so I started working on that. Somewhere while watching some videos I saw several where people had blast gates that switched the DC on and off and I was like that's awesome but they didn't go into much detail. I finally accidentally found one that gave a better idea of what products they used and bought the parts, tested it out and implemented it. It works great.

To turn on the collector I just open a blast gate. To turn off the collector I close the blast gate. Pretty simple and it makes it very hard to forget to close a blast gate and use another tool with reduced suction.

Short video of it in action: https://www.youtube.com/watch?v=59u5zHttUn4

The parts I used:

• PowerSwitchTail II
  
• Micro switches
  
• 20/2 bell wire
  
  Edit: Oh and of all the methods I used to cut the DWV piping (bandsaw for shorter pieces and cleaning up, sawzall with a crappy miterbox-style 90 cutting guide and a handsaw in the same guide) the handsaw I think was the easiest to get a nice cut.

It can be done.

To turn a fan on and off, use a relay. This allows the low voltage that the Pi can produce to control an electromagnetic switch that controls a much higher voltage, which the fan works off of. I assume you mean a 115V or 230V desk fan that plugs into the wall. (a relay board will work with DC-driven fans as well, and be safer with lower DC voltages.) If you haven't worked with exposed line-level voltages or aren't comfortable doing so again, use something like this:
https://www.amazon.com/POWERSWITCHTAIL-COM-PowerSwitch-Tail-II/dp/B00B888VHM/ref=sr_1_1?ie=UTF8&qid=1392872852&sr=8-1&keywords=power+tail

Consider using a Powerswitch tail 2 to safely take care of the high voltage work. It's rated for 15A resistive loads, so you shouldn't normally be switching your 12A inductive load with it. But as a power enabling circuit it should be adequate.

Stay away from those Chinese relay boards unless you know what you are doing.

Just use a different kind of whistle. I use this one for hunting as it carries a good distance and works well in windy conditions. Dogs also can differentiate between different whistle patterns. One sharp blast from me means sit and look at me, three tweets means get back over here, etc.

editing, shipping was outrageous. Trying again.

Cuz camping safety! Could save my life!

Here's to hoping! :D

Recommend Acme Thunderer.

Looks like a dog whistle.

You can buy this new on Amazon. This is not antique.

It's a whistle.

Shepherds use them for whistling commands to their sheep dogs.

Here, you seem to have dropped yours

Amazon sells what you're looking for.

The simplest (and possibly safest) answer is to get one of these PowerSwitch Tail II. It has a few screw terminals that you can wire directly to your arduino.

If you want something more complex and capable, I would look up relays. Just be aware that you are dealing with wall circuits could be dangerous.

Before my electric bill came today I was thinking of the following semi-off grid setup:


-----[solar system]-----

solar panel(s)

charge controller

battery(s)


-----[mining rig]-----

Raspberry Pi

Zeusminer Blizzard


-----[electrical stuff]-----

Samlex power supply


PowerSwitch Tail II relay


Raspberry Pi lamp timer circuit


buck converter



-----[The Plan]-----

Plug the Samlex into the PowerSwitch-Tail and PowerSwitch-Tail into wall. Hook the solar system battery up to the Samlex's battery backup terminals. Hook the Blizzard and Raspberry Pi up to the Samlex's 12v output (use buck converter to step the 12v down to 5v for the Pi). Finally, use a cron job on the Raspberry Pi to control the PowerSwitch-Tail. In the morning the Pi would use the 'lamp timer' circuit to open the PowerSwitch-Tail causing the Samlex to draw power from the solar system battery. During the night the Pi would close the PowerSwitch-Tail causing the Samlex to draw power from the grid. The Pi would also restart cgminer to mine to different addresses depending on which power source was being used. I would setup the cron job based on the capacity of the solar system. More panels and batteries would mean the system would run longer off of the solar system before switching back over to grid power. I think it would have worked, but not sure. I'm pretty new at this stuff.
