I made a power supply from a diy site, the schematics are above. The site showed the project as 2amps output but I'm not getting even close to that. I'm getting around .14A or less. Does anyone know what the problem might be. Also I didn't include the diode that is shown above the lm317, but I don't think that has anything to do with it. Lm 317 says its rated for 1.5 A. The Transformer I'm using is here
The Heat Sink I have is here
I have it connected to a usb charger for my phone, which should use max 5v and draw 1 amp. I'm using a multimeter to measure the current. It is dynascan 2807 digital multimeter.
Update: When the charger is connected the voltage drops to .4 volts?
Update 2: Never going to copy schematics from Makezine website again. Or do any projects from there. Secondly thanks for all the useful feedback Im learning a lot. What would be the best way to do a variable power supply then or is it just not feasible. Should I just make a power supply with 3.3 5 9 and 12 options or is my problem the transformer output is too high so after rectification its way to high? I really only wanted a variable power supply from 3.3 to 24 yet it is much higher than that because of rectification. I'm just gonna blame makezine again.(Although I could have done some research on how bridge's increase voltage
