Re: Convert PC PSU
I have enough experience on that. You may find TL494 PWM IC on the SMPS. find the feed back circuit from the output and remove the resistor there and put a variable resistor on to that. I did it several times this type of job. you can convert the PSU to vary the voltage upto...
how to build 3phase drive3 phase motor
Hey,
I am also having same problem. Have you solved the problem now? I also can share my knowledge with on AN843. I have CCS C compiler, and I found it is impossible to use for the same. Because Interrupt latency is not supported that fast.
As you know...
Re: voltage regulator
Please specify the current rating. you can use voltage regulator LM317, carefully go through the Datasheet., where you can find precise voltage control using LM317 from 0V. I also did it for a precise control equipment. I did it to vary the voltage from 0V to 24V with two...
Yeah,
You can get 5V from the Parrallel port, provided that you have to care on the current rating. If you want to get control other circuits you have to have a buffer or suitable ciruit.
Have a look at https://www.geekhideout.com for controlling parallel port.

Re: switching ckt problem
Hey,
Just use a Opamp. I think this is the most suitable way to do this. If you have further questions please let me know.
