The keys to my front door kept breaking off, so, just like everyone would, i built a bluetooth door opener :)

I've been updating the software of the DIY ledscreen, and started an endurance test! The screen with 40 leds you see in the video below has been running for a week and 48 hours EDIT: Almost 3 MONTHS now, although only readable with lights off /EDIT, on 2 cheap double A batteries. If you are not into Electronics, programming or microcontrollers, just watch the video and skip the post below ;) Otherwise, I hope its somewhat helpful!
I received a broken Led Lamp. Broken as in not usable, but all leds were fine.
So what i did was resolder all the leds in to common row anodes and common column cathodes.
2 74hc595 Shiftregisters drive the columns. The main board supports up to 16 columns now, i have led boards for 12, and 8 connected in the video.
The rows are sinked through transistors triggered by the MSP430.
