January 11, 2018 - Leds everywhere

A project log for The Cardboard Computer - IO is my name

My goal is a 4-bit CPU using recycled cardboard substrate and Diode Transistor Logic. This is an educational platform for me.

I was starting to run low on my led supply for IO and then along comes a New Years gift so to speak. I frequent my local Habitat Re-Stores almost every week and they put out items that did not sell or not in good enough condition to sell.

Habitat for Humanity is a great organization that helps build and provide housing for those who do not have the financial means to do it on their own.

This week it was a box of 14 led fabric decoration kits that were old and the internal batteries corroding. Overall there are 140 leds for IO. Red, yellow and green should be nice in addition to the blue/white leds I have been using :-)
