I would like to create a 50hz ttl clock, but I am unsure of the best way to do it. I was thinking of using a 555 timer, but it can be difficult to get a 50% duty cyle using the 555 timers. I was then thinking about a crystal oscillator, but it looks like they are for much higher frequencies. Are there any other options, or do I just have to make due with the 555 timer?
** Update **
Ok, I finished building my design and it is currently running off of a 9v battery. Is it possible to use a dc power supply that plugs into the wall that supplies 9v, and 1.5A instead? I am worried that the current will be way to much for my circuit. I know for a fact that my voltage regulator only handles up to an amp. So I guess my question is will the supply output1.5 amps to my circuit, or will my circuit just draw the neccesary amount of current to run.
