So I just got my first PCB in from batchPCB tonight. Its a LED driver shield using the TPIC6B595 shift registers as sinks for an array of LEDs. I'm using it to control an LED array for a beer pong table I'm building. Not the most noble effort, but its fun to have something to work on. Put it all together and was so excited I had to tell someone about it.
Here it is by itself
With the mega
Because its for a ruit table I've only broken out 20 of the 24 sinks. If there is any interest I can redesign it to have all 24 sinks broken out to jumpers and put it up on batchPCB market along with a bill of parts so it could be put together as a kit. You can get pretty much everything from digikey for SUPER cheap.
Here is a video of it in action (you might want to mute it unless you want to hear my girlfriend talk about some class she's taking)
