greeeg 460 Posted November 17, 2015 Share Posted November 17, 2015 Hey Guys, Exam times again, so I feel like I have a tonne of time for my projects. This is a project I started in February 2014. I found a very nice 8x8 dual colour LED display. I designed a PCB for them when I ordered them, instead of when I actually had them. I had built a PCB up with a G2542 8kb / 512b (Mem/RAM) but didn't manage to get it working. Over the last few weeks I got back into this project, and low and behold it did actually work!! I built up a new PCB because it was designed as a common cathode driver, but the displays were common anode.... (on the first board, I had bridged the common mosfets.) of course using 0402 parts. (this display need 64 of these O_O) back of PCB contains clock, half a DCDC stepup and a BMA222 accelerometer. Front & back Now I needed a case, this is my first project I decided to actually make use of a cheap chinesse laser cutter I now own. The piece with all the slits in it create a "living hinge" which creates a cool organic looking case. as opposed to a rectangle. I'm still working on improving code. Basic clock functionality is in. lastly I'll leave you with my dud designs. which while not very practical. are actually 100% useful. A failed design can teach you alot! I will be making this open source, I would like to make more in the future, which may involve buying more displays from china (if there is interest maybe even a group buy?? ) bluehash, tripwire, pine and 3 others 6 Quote Link to post Share on other sites
