Hi. I'm a Unix Administrator, mathematics enthusiast, and amateur philosopher. This is where I rant about that which upsets me, laugh about that which amuses me, and jabber about that which holds my interest most: Unix.

ATX Bench power supply build

Posted 08-12-2015 at 02:04 PM by rocket357

Still waiting on parts, but I've gotten the rails toggle switch and standby/power LEDs soldered in, and I have the load resistor in as well. Binding posts are holding up the entire show. Should be delivered today, I hope. After desoldering half of the dead electronics in the house, it felt good to put something together (even if I'm still not done).

In other news, my ATmega328P board is coming along nicely (not that I've actually *tested* it, as I'm waiting for the *ahem* bench power supply to drive it). I'm excited to finish them both so I can...write code.

Build hardware so you can write more software. Write software so you can build more hardware. All of life is a recursion, I suppose.

In related news, today I learned that the rPi has no ADC? Sure, you can run a secondary chip, but really? Perhaps I'm spoiled by my Beaglebone Black, but I figured these SBCs all had a baseline of components. I suppose ADC isn't really a "baseline" component, then. You learn something new every day.

I'm tempted to break out the BBB and wire up a bunch of analog sensors so I can send graphs to all of my rPi friends. Sure, they can get an ADC chip for $4 more, and that means the rPi is still cheaper than the BBB, but it'd be fun to ruffle their feathers =)

    And the short-circuit protection works like a *charm* (don't ask, just...don't ask).
