  1. What is it? 4 digit BCD counter using LaunchPad and two 74HC595 shift registers. Note: One important thing that I forgot to add is that since I am powering this from LP, I am using here 74HC595 and not HCT. LP provides 3.6V, HCT needs 5V. See it in action: #include unsigned int counter = 0; // Counter variable void main(void) { WDTCTL = WDTPW + WDTHOLD; // Stop WDT P1OUT |= 0x01; // Port P1.0 will be used to latch P1DIR |= 0x01; USICTL0 |= USIPE6 + USIPE5 + USIMST + USIOE; // Out & clk enable, SPI Master USICTL1 |= U

  2. Looks like EagleCAD. The free version is quite useful (get the SparkFun parts library!). The only limits are the PCB size and layers (2), which are fine for almost anything you will want. If you end up sending your design for professional boards, I recommend dorkbotPDX. Great price, and awesome quality. Also, he'll take your Eagle file, so you don't have to produce individual Gerber files.

    Blue, hit up to walk through the door. Didn't you ever have a NES? On a side note, I wish TI's people were working on improving the estore and their website instead of spending time on viral marketing. I guess it does, however, show they're interested in us hobbyist types.
