Create package It was easy to put together, there's an instructables.com post on how to put everything together. Very handy, I've been able to since make a reverse joule thief to charge my lipo batteries
The "Yet Another Programming Shield" was very easy to assemble and had great directions available. I have only programmed ATMEGA328P-PU chips so far but I'm sure it will work just as well for the ATTINY chips.
This is a great little project. We have made joule thieves before (see image) but had to source all the materials and build them ourselves. It is hard to beat the price of the Easy Joule Thief Soldering Kit even sourcing and building them ourselves.
The URL on the package didn't work. I googled "Easy Joule Thief Soldering Kit" and found the instructable for documentation. The kit was easy to put together after that. I couldn't get ten turns on the torrid using the included wire, however the 8 turns worked OK. I used about 20 turns of 28 gauge different color enameled wire on second one and it works well too. Having a switch is nice. It is almost too darned bright!
I bought Yet Another Programming Shield can program ATTINY, shield It fills my needs perfectly. Using the sketch I find the site of a piezo Adafruit is added at the location provided on the circuit. Delivery side I totally Satisfied. thank you
I bought one of these, and they were such a hit with our family that we ended up buying more than a dozen. They're simple, easy to put together, great for learning how to solder, and are quite enjoyable after the assembly. I highly recommend them, especially as a little glowing trinket or something to use up those "dead" batteries.
