276: Playing a Song on a Potato
from Embedded Hosted by Logical Elegance
Jesse Rutherford (@BentTronics) gave us an in-depth look at the 555 timer IC (wiki). Jesse runs Bent-tronics.com and wrote The Ultimate Beginner's Guide to the 555 Timer (Amazon). Some great 555 projects: 555 Decimal Adding Machine 555 found in a drill trigger speed controller as seen on the Ben Heck Show 555 found inside a solar charger controller, video by Julian Ilett Somehow, despite it being in the plan, we didn't mention the Evil Mad Scientist The Three Fives Kit: A Discrete 555 Timer which builds a 555 Timer out of discrete parts. If only the creator would come on to talk about it and his other cool projects. Note that EMS also has a great description of how the 555 timer works. The giveaway is Jesse's book and the components to build the projects in his book.
