Reddit mentions of microtivity IM206 6x6x6mm Tact Switch (Pack of 12)

• Fire TV Stick, which is a lower-cost alternative to the awesome Fire TV. (think Apple TV, but actually good)
  
  
• Raspberry Pi which is a tiny fully-functional/fully-featured ARM computer.
  
  
• Arduino, which is an easy-to-use electronics prototyping platform, great if you're interested in learning how to make your own electronics and whatnot. (you might also want this, this, this, this, and this. Should be less than $40 altogether, though you could also probably find like a starter kit that comes with an arduino, book, and components.)
  
  
• Huion drawing tablet, great for if you want to do digital art. I haven't used this model specifically, but I do have the (bigger/more expensive) Huion 610 Pro, which I love.
  
  
• Amazon Prime student was like $40 IIRC, not sure if that has changed though.

I spent a long time trying to find ESP resources too, I can't help you breadboard it, but this is what I use for my ESP-01Ss:

You'll see in the reviews of that item that you need to add a push button to it (literally 2 solder points, and there are pictures)

Something like this would work, you might be able to find cheaper:

Once you have the development board with the push button on it, you put in the ESP-01S, hold down the button while you insert the usb to your PC, then run whatever software you want to write to the esp.


Hope this helps!

So I assume these will work perfectly?
