I am in search of some help. I am trying to build a power supply to run a basic "tank" circuit. The coils are just over 2 ohms, and I am using a 47mF capacitor in parallel with them. The power supply needs to be in the range of 1- 20 Volts, 2 amps, with a 10 turn potentiometer...
Can anyone tell me the best place to find some standoffs that accept a #8-32 screw? I am having a hard time finding them- I need them about 1 1/4" long, and threaded on both sides. Can anybody help?
Can anyone tell me where I can find plstic bobbins for winding coils? I want to build coils with 24 AWG magnet wire, with a low carbon steel cores. I need to find the cores and the bobbins- if anyone can help me I will be eternally grateful!!
I pulled a hairbrain stunt and I thought maybe you guys could get a slight laugh from my misfortune... I am a tattoo artist living in a small apartment. I decided to work on a client in my home, and preceeded to work on his piece for three hours. I put a dvd in my BRAND NEW television and was...
I have been searching for the cheapest, easiest design to build a power supply. I am pretty new to this, but I found a design using an l200 voltage regulator that would work great. I iam not sure what sort of power output I need though. The load will be two eight or ten wrap coils with 24...
I am trying to build a power supply design- but all they say is L200 for the voltage regulator. Can anyone tell me anything about this IC, preferably how to obtain a data sheet? Thanks.

I am building a power supply with an philips ecg 957 voltage regulator in place of a LM 317 voltage regulator. I am not sure what polarities I should change on the circuit- does anyone know where I can get a spec sheet?
I have a fisher ca-272 home amplifier that is giving me some trouble. I bought it off of a guy that knew nothing about audio equipment, and had hooked a jumper wire across both left channels (I am guessing to try to bridge the channels...) and he said it played a little bit and when he turned...
I am trying to use an ecg 957 voltage regulator in place of a LM317T radio shack voltage regulator. They both have about the same specs, but the ECG 957 is -1.2V to -37V instead of poitive voltages. I am building a basic power supply, and I am thinking I will have to change the connections...
I know this is a simple circuit but I am in need of a little expertise on this one... I have an on/off footswitch and I wanting to make it wireless with as few parts and $$ as possible. It doesnt have more than about a ten foot range, but it has to be dependable. I think that I just need a...
I am working on a custom designed power supply for my tattoo equipment. I am looking at a commercial bought power supply and it basically is an unregulated power supply. When I hook the leads to the output, it reads 39 volts. It uses a non-center tapped transformer, which reads 28.4 Vac...
