Run-away class

I had tried to make a class to teach how to make basic PCBs. The project was a simple RGB LED and and some resistors to limit the current so that it could be driven directly from the pinouts of an arduino. Unfortunately, I got a bit out of hand in creating material. The part introducing students to LEDs, PWM, measurements of luminescence, and basic V=IR  stuff is mostly complete.

In hopes these documents may be useful to someone else, I have uploaded them here.

Needlepoint ladybug

Stocking Frame

My brother has a Christmas stocking that was made by our great grandmother probably thirty or forty years ago. Due to its age the backing was starting to come off and there was not a good way to display it without risking damage.

Crypto for dummies

I decided to mess around with cryptocurrency mining for fun. I don’t expect to make any money, and you shouldn’t either, but if you want to know more about it, mining is a good way to go. I hit a few snags along the way though, and this might help you get past them a bit faster.
