Hi guys, first time post here. I've recently decided to try again to learn a little more about electronics. This was started by finding a Velleman kit (K8006) in the clearance bin at my local electronics store. I finished the kit and did a damn good job, imo. I also built a small fm transmitter that doesnt work, atleast I have been able to get anything out of it.
I have tinkered with electronics for years (I'm 36 years old), so I'm not a total newbie, but there are some basics I don't fully understand. I have a nice breadboard and a decent selection of components and I'm ready to tinker! Currently I am trying to convert an atx power supply into a bench lab type supply. I removed the guts from the metal enclosure and mounted then in a cigar box. Today I will mount the terminals, trim the unused wires, install a power switch and an indicator led. I would like to install two analog readouts for voltage and amperage for one set of terminals as I would like for these to be adjustable, I will definitely need help with doing that right. At the moment I have a few things I need help with first, though. First, my power supply did not have any white (-5V) wires, can I do anything to create a -5V terminal? Can I take one of the extra +5V leads and somehow reverse it's polarity? My other thing is I have need for a 24VAC supply in order to run my Velleman project I built. I will also need to build a module before I can test it but getting a 24VAC power supply is my first goal. How should I build this? Can I get that from my atx supply by combining two 12V leads and converting that to AC? I don't even know if that's possible. I am at your mercy, guys.
Thanks for any help and I look forward to bein' skooled! Below are some pics of my first real soldering jobs.
