    0-30V Stabilized Power Supply

    I'd rather stay with the potentiometers, because I think it would get me annoyed to push buttons from 0V all way to 30V :D But I think you want digital to analog converter. Or maybe you can make something with the PWM signal.

    0-30V Stabilized Power Supply

    Of course, leaving fans non stop has it's own pluses: less heat in the case, but it is the most simple way. For us - electronics it is not fun... :D Sometimes I think, why factories can do better, why cannot I built even more better project, even it is not worth the price, but it is fun...

    0-30V Stabilized Power Supply

    Think about auto cooling system using some of the thermal sensor with AVR. It very easy to do that using atmel microcontroller, thermal sensor and the L293 logic motor controller.

    Will you try the avr programming for vmeter and ameter?

    0-30V Stabilized Power Supply

    I think that link should be put on the top of the project page, moreover, someone should make new tutorial for building this project. For example you, effenberg0x0, when you done your project :D Maybe I could make some tutorial after 2 months with pictures and schematics and pcb and periphery...

    0-30V Stabilized Power Supply

    So it the only matter how to connect the end pins of pot is how you want to adjust voltage. First way: turning clockwise increasing voltage. Second way: turning clockwise lowering voltage. Now I understand :) The middle one stays the same in both ways.

    0-30V Stabilized Power Supply

    OMG how cheap  :'( I've been searching for shop to make the transformer for me for a few hours, but no luck. I tried to search for already made trafos and found such: Toroidal mains transformer 160VA 230/30V for 40$. So for 2 it would be 80$... It would be perfect, but the price for the...

    0-30V Stabilized Power Supply

    effenberg0x0, if it's not a secret, what was the price of you transformer? And to be correct, if I want to build the version of the project 0-30V 0-3A, then I need secondary winding 30V and at least 4A?

    0-30V Stabilized Power Supply

    Thanks for reply, audioguru, So were I right saying that one is ground pin and two others are adjustable resistance? And were I right saying which pin should be connected to looking at the original project? I know that it has to be completely separate power supplies, and the question is: which...

    0-30V Stabilized Power Supply

    effenberg0x0, I saw that table and I appreciate for you comparing parts :) The only thing left for me is to buy some new parts and the transformer (which is the worst thing, because it costs much). Someone, please answer my question which i posted before about the pot connection. I need to...

    0-30V Stabilized Power Supply

    If only I saw this conversation a few days earlier... :D Last night I built the PS using schematics and part list from the original version... I tried to test it: connected voltmeter to the output, then turned it on, led blinked and I saw a voltage on the voltmeter. But it doesn't matter anymore...
