I diddnt want to hijack the Binary clock thread Robotbuilder started, so I started my own. On this schematic, He has SPDT switches to adjust time. What kind of switches should these be? I ordered toggle switches, but I am unsure now.
Good, Because I fixed the order for microswitches. How can I pull more mA out of the TTL outputs? I know about hooking them up to transistors, but That would take too many. Any advise that is simple? I am using cheapo red LEDs.
I have the 1hz clock working. It works perfect. The 8ma is perfect for the LED. It is still pretty bright and easy to tell its on. Im happy Im going to finish it tonight!
Lol I did not finish it that night, I fell asleep on accident
But the question I have now is this:
The circled part of the schematic is confusing. It has x's and other marks that are confusing to me. Perhaps you could take a look and figure out what is going on?
Also, Ignore the circled blue part. I circled the wrong part rofl
