FINALLY got the clock working today...
10th try, just shy of 8hrs of work(learning how the chip worked as I went), and $20 so far... have to run and buy another board to make it on to leave it(not going to solder it in, easier to replace parts on the protoboard)... so $40 + taxes, gas for 3 parts runs, and more stress... or just buy one premade for a couple hundred. NO tinker factor in those though.
Feels great to have my own project done, from scratch(even if I did get the plans online, I modified the output current so I don't get blinded by the signal LED running at 25mA).
Still going to modify it to have 3 switches before I'm done(power, 1Hz, 10Hz), but working is good enough for today. Can add the other 4 frequencies later(100, 1K, 10K, 100K) just by adding the capacitors and switches.
