Tweet-a-watt - Numbers Fading, Long Delay
Assembled a tweet-a-watt today and having an odd issue. Instead of the 2 second expected delay between LED blinking it seems to be doing so every 7 seconds, and each time it does the display dims considerably. The voltage readings seem very off the entire time. I expected it to last the first 30 seconds or so, but even after 5 minutes of having it plugged in I received the same thing. I've triple checked all solder points, resistors, capacitor polarity, and wiring - but I'm stumped. Any help would be greatly appreciated!
