My usual way to power something with 5V? An old cell phone power supply. My usual way to power something with 3.3V? An old cell phone power supply, connected to a 3.3V arduino micro. That has to stop, so I asked my dad for an old power supply he surely had laying around and ordered some parts on the usual places. The plan is to use the 12V, 5V and 3.3V as seen before on so many places. Additionally, there will be a variable output controlled by a LM2595(ebay) with a LED display voltage meter (ebay). Now I just have to wait for the copper chicken head knob for the 10k resistor and the resistor itself, but nothing that should hold me from starting, though. *While writing thinking edit*: I need those min load capacitors. Sounds like some really tough math to get involved to.
No such things as 5 ohm I could find, so I'm looking for 4.7 ohms.
Yeah, I just wanted to play with the latex feature, I admit it :D Next on is the wattage.
I ended up buying LSR-120/20, LSR-33/10 and LSR-47/10, they are not the cheapest, but I could get them all from one seller and hope on some combined shipping costs, thanks ebay, for finally making this possible. I'll use some plywood to place the ports, the display, power good led and the potentiometer - and should not forget the switch.
Well, so much for planning, not the best page I wrote, but it's supposed to be more a log this time - a note to the future me. That's why I gave it the title. Why do I explain something self-explaining? I'm tired.
#ATX Benchtop Power Supply - quite nice instructions, but don't cross the streams like he did!
#Bench Power Supply - ATX PSU Adapter - he can even reuse his PSU or change it for another!
#ATX power supply conversion for bench usage - the reason why I won't make a project out of it - the third great write up :)
