A Programmable Circuit

The above schematic is one for a POV Display system that works on the same principle as a Dot-Matrix printer.  You can program in graphic columns (or rows) of 8 bits each and then scroll through all of the memory.  If you move the device fast enough, you should be able to see the programmed image.  If the output LEDs were inkjets, the device would "print" the image.

KTechLab - Building a Working Memory Circuit

Today, the goal was to test out a new (to us) circuit board design app for Linux called ktechlab.  We came up with a preliminary memory circuit (just to see if we could) so in the future, we could implement it into our bot.  KTechLab was a good tool, but the Documentation is slim, and the website is down, so it was a bit of trial-and-error until we got our simulation working.  But it does indeed work.  We can store 2 bits in any of the 16 locations... that's a whopping 32 bits of memory!
