Cardboard record player

[Yen] tipped us off about this cardboard record player. It’s a marketing tool that you receive in the mail. Inside the cardboard packaging is a record and the packaging itself can be folded into a player.

Hackable handheld

The NanoNote is a tiny handheld housing a lot of power for a small price. It ships running openWRT and sports a full keyboard, 336MHz processor, 32 MB ram, and 2 GB of flash memory. Not bad for $99. [Thanks Drone via Linux Devices]

Virtual page flipping physical interface

Love reading ebooks but miss flipping through the pages? [Marcin Szewczyk] developed this interface that lets you flip a couple of sheets of plastic to turn and fan through pages on the screen.

Augmented reality tat

Not interested in supporting an ink artist or just can’t decide on the design? Perhaps you should get an augmented reality marker tattooed on your arm and have the art digitally added for those who have already made the switch away from using their analog-only eyes. [Thanks DETN8R via Asylum]

Cooking with a CPU

[Bo3bo3] is practicing the art of cooking with processors but he’s bumped things up a notch. Instead of cooking inside a computer case, he removed the processor from the board and made it USB powered. [Thanks Waseem]

Laser tattoo

We’re amazed we didn’t stumble across this ill advised burnination sooner. Earlier in the week [tetranitrate], of LED chess set fame, posted his experiences using a laser cutter to scarify his own skin. It’s very painful, not to mention the discomfort of smelling your own burning flesh. He’s using an Epilog with a magnet over the safety switch. To get the positioning right, a layer of painters tape was put down and then etched. For a less painful version, you could try Bre’s fingernail calendar from last Fall. Video of multiple tattoos embedded after the break.

Back from Belize extra

Yesterday, I was standing on a tropical island off the coast of Belize. Vacation rocked with lots of SCUBA diving, spearfishing and snorkeling. I’m back home, shaking off the jet lag and clearing up my inbox. Thanks to [fabienne] for filling in and letting me unplug for a while!

[Darkrom] has set a new standard for Hack-A-Day readers… I haven’t seen it in person, but that looks like a legit Hack-A-Day tattoo.

[null] sent in a new use for a frequency generator, a spare car amp, a sub-woofer and a plastic coffee can – brass cartridge polishing.

[LoopyMind] sent in this Game Boy Advanced Movie Player IDE hack. It’s pretty much a direct CF to laptop drive cable with an external battery supply.

[Dingolishious] sent in a POE UPS/remote power control solution. Could be handy if you’re using many POE devices, or if you’re having power issues. He added an inexpensive remote power monitor/switch solution behind his UPS. It senses power outages and kicks out an email – and allows remote power cycling of his POE devices. Of course, if you’ve got a linux box behind the UPS, it can monitor the output from the UPS and send notifications.

[William] added a preamp stage to his iKEY usb recorder. looks like an interesting toy – it’ll record audio directly to a USB flash key. The pre-amp allows him to record in more challenging environments.

[Andrew] noted a simple mod to increase the deadly fire power of the ubiquitous airsoft pellet gun. It’s just a matter of reducing some extra space in the spring compression area.

Last but not least, [VIPER] modded his projector to use a 12v halogen headlight bulb. Not a bad idea – at one point I was pondering a 550 watt source four halogen as a possible replacement.
