Contact Lens Case Fuel Cell
Cheap and Easy MP3 Shield for Arduino
MP3 Interface for Arduino: Cheap and Easy
This is useful, not for the MP3 implementation rather just knowing how to simulate the button press in another device. As for the MP3 player functions, I just uploaded my first instructable showing how to make a network controlled mp3 player using the ESP8266 and a serial controlled mp3 module. The whole thing cost less than $8, so that's truly inexpensive !Check it out. http://www.instructables.com/id/WiFi-Enabled-MP3-P...
Awesome Instructable, even if I did have to look up IB and MYP. ;-)This is a Senft Stirling engine, first conceived and developed by Dr. J. R. Senft of University of Wisconsin River Falls, during a friendly competition with Dr. Ivo Kolin of University of Zagreb in the 1980's to build an engine that would run on the lowest temperature differential. Dr. Senft, an awesome machinist as well as a mathematician, was an inspiration to me as a teenager reading Live Steam magazine, and one of the reasons I became an engineer. A neat illustration of the engine and the story behind it is here: http://www.animatedengines.com/ltdstirling.htmlThanks and keep on making Instructables!
