hello,
I'm new here and need some help with my first driver. I build the lm317 driver and test load from rog's website. everything was going fine untill i got to the test section. i hooked up my first driver to the test load and connected it with 2 cr123a battery's wich gave me a total of 6,43V.
I first tested the voltage on the test load, it was 5,83V wich is not good i think, it also wasn't changing at all when i turned the pot up/down. then i tested the current in mv on the 1 ohm resistor, but i got no results:undecided:.
And when i connect my multimeter to the regulator i should see 1,25V but i got no result.
I got an lm317 with 8 pins, 4 of them are Vout. Does it matter on wich Vout i connect it? maybe thats the problem. This is the one I got -> Conrad Electronic - Europa's grootste webwinkel in elektronica en techniek
I also broke the positive pin of my 20x LD by bending it accidently, is there a way to fix it? I tried to solder a wire on it, but just it fells off when i touch it
hope to get a reply fast
