Hackaday Links: August 25, 2013

[Adrian] came across a treasure trove of 507 mechanical device designs. It didn’t seem quite right for a Retrotechtacular post, but we wanted to share it as it’s a great place to come up with ideas for your next Rube Goldberg machine.

Biking with headphones is dangerous. That’s why [J.R.] built a handlebar enclosure for his Jambox Bluetooth speaker.

While dumpster diving [Mike] found a Macbook pro. It was missing a few things, like a keyboard, touchpad, battery, ram, and storage. He borrowed a power supply to test it out but without the keyboard there’s no power button. He figured out the traces on the motherboard which turn it on when shorted.

[Mateusz] want to let us know about the Hercules LaunchPad. Like the other TI Launchpad offerings it’s an all-in-one dev board. The Hercules line features a couple of flavors of dual-core ARM chips. Can you believe the dev boards you can get for under $20 these days?

After seeing the ammo can sound system about a month ago [Ilpo] was inspired to share his ammo can PC case with us.

And finally, here’s a way to display your Bitcoin mining rig for all to see. This system was laid out in an antique frame and hung on the wall.

High Explosives PC Case

[Ilias] let us know about his new HTPC case mod.  He took a surplus Ammo-case and with a bit of work turned it into a livingroom eye-sore masterpiece. His build has some nice touches, including a slot-fed DVD player, switch-based fan control, and key-and-button “nuclear launch” type power-on controls.

A few things to learn from this project: Cleanly cutting holes in a steel case for the connectors is tough.  You can see that [Ilias] did a pretty good job with it and in several cases used rubber gaskets to cover the rough edges. Secondly, the slot fed DVD had to be mounted upside-down.  We assume this will be fine, but we’d like to hear a follow-up after a few years of heavy use. Finally, the GFAF (girlfriend acceptance factor) ran very close to critical on this build as [Ilias] didn’t clean up the metal shavings on his porch and ended up with rust stains everywhere.

Case mods are an enjoyable hobby. We hope this will inspire you to take the leap.  If you do, don’t forget to send your completed project into our tip line.
