I have been building a few drivers and recently tried my luck at an analog driver.
Part Value
C1 100nf
C2 100uf
D1 1N4148
D2 1N4148
D3 1N4148
IC1 LM358N
IDLE 10K RTRIM64W resistor
LED1 power LED3MM led
MAIN 10K RTRIM64W resistor
R3 10K
R4 10K
R5 10K
R6 10K
R7 1K
R8 10K
R9 1R
R10 10K
R11 10K
R16 calculate for diode type
T1 BD437
Thats all the schematic info i have for it.
This is what i built. I did make a change my transistors anre now turned 180 due to the pin outs are different.
This is what my board looks like.
Okay and it called for 1ohm resistors for one and a .33 ohm resistor on the other. all i had was smd resistors so i used 3 1ohm on the one board and 1ohm on the other.
I have one running at 12v and its outputting 1.3A and another running off 5.5v and it outputting 400ma.
But i cant seem to get the signal wire to work. i put it to 5v high and nothing happens.
Also i did not have the same npn transistor so i used,
MJE3055Tjp instead of the BD437. (i suspect this could be my problem.)
Also i had to mount my pots vertically as i did not have the same kind.
i am using a pc power supply.
Sorry for the long post but i just wanted to make sure that everything was listed and shown for the best possible answer.
