Hacker Builds New Single Board Computer Out of Old Single Board Computer

[Ncrmnt] had a busted tablet PC with an Allwinner A23 SoC inside. He combined two of our favorite past-times, Linux hacking and 3D printing, to make a rather sweet little single-board-computer out of it, giving the tablet a second life.

Step one was to make sure that the thing works. Normally, you’d hook up a wired serial terminal and start hacking. [Ncrmnt] took it one step further and wired in a HC-05 Bluetooth serial module, so he can pull up the debug terminal wirelessly. The rest of the hackery was just crafting a bootable SD card and poking around in the Android system that was still resident in the flash memory of the system.

Once the board was proven workable, [Ncrmnt] designed and printed a sweet custom case using Solvespace, a constraint-based 3D CAD modeler that was new to us until recently. The case (after three prints) was a perfect fit for the irregularly shaped system board, a 3.7 V LiIon battery, and a speaker. He then added some nice mounting tabs. All in all, this is a nice-looking and functional mini-computer made out of stuff that was destined for the trash. It’s fast, it’s open-source, and it’s powerful. Best of all, it’s not in the dumpster.

There are pictures and more details on his blog, as well as [Ncrmnt]’s TV-stick to computer conversion that we’ve covered before.

Oven parts scrounging


In response to last week’s post about parts scrounging with a heat gun, Hackaday forum member [BiOzZ] decided to try doing the same thing in his oven. It seems to work quite well, but we’re wondering if there should be any concerns over the lead content of the solder. Anyone care to chime in?

Spill-proof parts holder


Have you ever been in the midst of disassembling something and knocked over your container full of screws onto the floor? [Infrared] has a simple solution to the problem which also happens to keep a couple of plastic bottles out of the landfill.

Easy button stops abuse of the word awesome


Do you often repeat a word ad nauseam? Make author Matt Richardson does, and he hacked a Staples “Easy” button to help him break his addiction to the word “Awesome”.

Cheap Remote-controlled baseboard lighting


[Sean] scored a pair of LED deck lighting kits for a steal and decided to install them into his newly renovated kitchen. They are currently remote operated, but he plans on adding an X10 interface as well as PIR sensors for automatic triggering in the near future.

Yet another LCD recapping guide


It starts with a finicky backlight, or perhaps a high-pitched whine from the back of your display – by now, we’re sure that everyone knows the symptoms of an LCD panel that’s just about to die. [Eric’s] Syncmaster recently quit on him, so he pried it open and got busy recapping. It’s running again, and he wanted to share his repair process in case others out there own the same display.
