I just finished another burner....
I was shooting for @ 200-250Ma current..as I am well covered thermally...Huge heatsink.
This is a GB diode...
I have (2) 10 ohm 1/2 watt resistors across the LM317
I am only seeing 185 Ma current (I am using a sense resistor for accuracy)
Ok..If I use my math..I need 4 Ohms (I have 1/2 watt 3.9 Ohm resistors..but need 1 watt)
I also have 5 Ohm 1/2 watt resistors...and a TON of 1/4 watt that came in a Radioshack pack!
How can I cut the 5 Ohm total at 1 watt down by 1 ohm???
I don't have (2) 8 Ohm 1/2 watts to use....
Basic electronics...I know....but I need help!!!
Thanks!!!!
