Overkill Phone Charger, Because, Well, Why Not?

ATX Phone Charger

There are times in a tinkerer’s existence where it is convenient to have the ability to plug in and power a lot of USB devices. Sure, you could use a USB hub but this may not be satisfactory if your devices require a lot of current. A computer may work but is not really a stand alone solution.

[Jeff] and the crew over at Make Lehigh Valley ran into this predicament. They were putting on an Adafruit Trinket class and needed a USB power supply to power all of the Trinkets that were going to be used. As any makerspace would do, they built their own USB Power Station, and the final product is certainly overkill for what they needed (that’s not a bad thing).

An old ATX computer power supply is a logical component to use for this type of project. These power supplies are usually available in abundance and will provide all the amperage any reasonable amount of 5v USB devices can ask for. The 5v output from the ATX power supply was wired to 8 USB jacks. Keeping up with the project’s resourcefulness, those USB jacks were scavenged from a couple of old PCI-slot USB hub panels. Not satisfied with only USB outputs, the guys also wired up some banana jacks so that 3.3, 5 and 12 volts were available for whatever project was being worked on. A 3D printed enclosure keeps everything neat and tidy.

This project used a bunch of recycled parts and solved a problem faced by the group. If you’re interested in using an ATX power supply to make a more bench-top style power supply then check out this build.

Not Your Typical ATX Power Supply Hack

Not Your Average Power Supply Hack

Power supplies are essential for at home tinkering and electronics hacking. Unfortunately, they’re really quite expensive, and a bit out of reach for most hobbyists. Computer ATX power supplies are a cheap alternative, although they usually tend to lack the features of real bench power supplies… unless you hack yours like [Mark Schoonover]!

When [Mark] set out on this project he wanted to use as many recycled components as possible, but still come up with an extremely functional bench top power supply. He snagged a 500W ATX power supply from one of his kid’s old desktop PC’s, grabbed some old wall-warts for individual current limited supplies (apparently ATX PSU’s don’t have 5V rails anymore?), and put it all into a nice big project box.

He’s even thrown in a voltage regulator with current metering and a nice set of 7-segment displays!

An AT-ATX: A Different Kind of Power Supply

FM48Q03HS8FVCVW.MEDIUM

[Jedii72] needed a power supply. A quick search online revealed many instructions for building one out of an old ATX power supply, but — he didn’t want just any kind of power supply — he wanted to build an AT-ATX.

He started with a vintage AT-AT toy from the 80’s, and then began cutting it into pieces. Hold for gasps of disbelief. Don’t worry though — it was in poor condition to start with, so it was never really considered a collectible. After cleaning over 30 years of grime and dirt off the toy, he gave it a fresh coat of jet black paint — not exactly canon, but it does look pretty awesome. You know, it would make a pretty awesome Sci-Fi contest entry, don’t you agree? [Read more...]
