Evolution of a Blog

This blog has evolved as I have as a maker. It starts at the beginning of my journey where I began to re-tread my tires in the useful lore of micro electronics and the open-source software that can drive them. While building solutions around micro-electronics are still an occasional topic my more recent focus has been on the 3D Printing side of making.

Bright Idea re RPi GPIO - NOT!

So I had this bright idea that I could use the RPi's GPIO pins to offload some processing from the Arduino and save some latency in my command processing loop.   Got my ribbon connector all nice and sorted out, connected up the appropriate sensors to voltage dividers to get them down to 3.3v, and only then read the f-ing documentation.    The pins are binary!!!  Doop!
