Description

Discussion of electronics for beginners and experienced alike. Hopefully we can all exchange ideas, circuits, schematics, and pictures of all disciplines of electronics including both analog and digital.

When asking for help, be specific, please. But don't forget to give us the big picture. Often it's easier to help solve your problem, than help solve your solution.

Also visit the Homebrew_PCBs list for information on making printed circuit boards: Homebrew_PCBs

Please note, this is -not- a job posting board.

Re: DC motor control circuit Tony, Learning about switching power supply is a good thing. But if you are interesting in the final product (sky tracking camera mount) and not out to learn Posted - Wed Jun 19, 2013 5:44 am	Jong Kung jongkung01 Send Email
Re: Two LED Flasher Circuit Tony, As Steve noted, you have to be careful that your LOAD (the actual circuit outside of 555 config) is not too big. With this configuration, your 555 output Posted - Wed Jun 19, 2013 5:31 am	Jong Kung jongkung01 Send Email
Re: Two LED Flasher Circuit Hi Steve: Many thanks. So something like a 470 ohm resistor from pin 3 back to pins 2 and 6 ? Posted - Wed Jun 19, 2013 4:23 am	Tony tony8fs Send Email
