Shown is a little side project that I have been working on. The EZ430 RF2500 board sends 288 bits to the TLC5947 LED driver every time the tiny green LED blinks.
The TLC5947 is a 24 channel PWM controlled LED driver. Each channel gets 12 bits of greyscale information and can drive up to 30mA of load at up to 30V supply. You can drive LED's or even tons and tons of relays (as long as you don't need more than 30mA!).
Interfacing with the chip is really easy, it uses a serial shift register interface where one clocks in the data bits and hits it with a latch pulse to make the data 'go live'. It also has a shift out so that you can cascade as many of them as you want. The copper wings are heat sinks because once I find enough identical LED's I'm going to drive them at full brightness and the chip will probably get a little warm.

This whole thing will live in a bookshelf and be powered by an IKEA LED driver that is in the bookshelf anyway. But the power needed to be downshifted and filtered to work the way I wanted it.

Originally delivered to Lufthansa CityLine in May 2003 as D-ACPS "Berchtesgaden," this jet has flown for Elite Airways since January 2016.
You see a lot in this view-- the numbered traces in the lower right are were everything happened. I crossed off long segments after they got soldered, to see what to do next.

Setting up the 555 IC to make its first connection-- a tricky one from the diodes across two pins. Spacing matters here so taped it over the 1:1 print before soldering.
Universal ABIT IN9 32X-MAX
The ABIT IN9 32X-MAX is based on the NVIDIA 680i SLI/SPP190 platform and supports Intel's Core 2 Duo and Quad Core LGA775 processors up to 1333MHz FSB. There are two PCIe x16 slots for users who want to configure a NVIDIA SLI graphics system. Other features include a 5-Phase Digital PWM, six SATA 3G ports, two Gigabit Ethernet LAN ports, two 1394 IEEEa ports, Dolby 7.1 Ch HD audio and Silent OTES cooling technology.
