Punch your alarm clock


This is probably the most entertaining “application note” I’ve ever seen. These things are usually a bit dry, ok, they make your eyes turn to a previously unknown state of matter. This one involves making your alarm clock snooze when you beat it. The trick? Wire an accelerometer to the snooze button. It takes a bit of supporting circuitry, but looks do-able for anyone worth of their soldering iron. Thanks to [Andy] for sending it in.

Hey, we have a tips line. Send in your hacks!

Pandora’s battery (unbrick your PSP)


[krazywhiteguy310] let me know about the announcement of the Pandora battery hack. It’ll cost you a Sony PSP battery to pull off the hack, but once you’re done, you can use it to jump start your bricked PSP to load up a memory imaged designed to unbrick the PSP. (I haven’t tested it, so I’m taking this on faith) Excellent news if you’ve bricked your PSP.

Pervasive Health Monitor (Got Granny?)


[Reza] sent in a project that he’s obviously put loads of work into. His Pervasive Health Monitor is basically a bluetooth enabled health telemetry recorder/transmitter. I think it’s an absolutely excellent piece of work. He’s offered to post more technical details if we have enough interest – It’s got my vote.

The video (after the break) starts off a bit dry, but trust me – it’s worth checking out. The monitor sports a TI MCU, bluetooth chipset, flash socket, multiple signal amps and onboard audio amplification. The PocketPC is showing the real time data stream being delivered via bluetooth.

Finally networking my new house extra


My new house is taking far more time to get into shape than I ever imagined. I’ve finally gotten most of the network and coax drops in place, and I wanted to show off my new mini-rack. Behind the door up top, my home theater gear is hiding. Below, my switch, patch panel, firewall and cable modem are happily humming along.

[Benjamin] send in a quick post on messing with DoorKings.

Another [Ben] sent in this cheap-o multi-touch interface. It’s just a webcam, a glass desk and some software.

[Tarun] sent in this interesting low cost laser range finder project. It’s webcam based, but uses a laser line (laser level style/simple beam splitter) to measure distances.

Oh, I’m freaking house poor this month, so I’m selling off some of my toys. (If you do buy something, let me know and I’ll put some stickers in the shipping box, but only on request – As a rule, we don’t sell our swag!)

Yes, we’re going to do something to get more stickers out there, so stay tuned.

Tiny inline headphone amp


[Jesse] sent in this headphone amp. It’s really just a board with a dedicated smd headphone amp chip(MAX9725) and a pair of smd caps recycled from an old hard drive, but it does job. I think the goal is to boost low signals rather than the usual audiophile quest for cleaner tunes.

DIY Encrypted NAS


I like the idea of keeping my data private, so I thought you guys might like this how-to that [mark] put together. He mentions some decent dedicated distributions like FreeNAS and Cyrptobox, but he used OpenBSD for his.

Python on the Telit GSM/GPS module (vehicle tracking)


[Nick] caught [Alex]s GPS enabled AVR, so he sent in his project using the same Telit GM862 module. Rather than depend on an external AVR, he wanted to use the on-board python interpreter. Apparently, documentation is a bit sparse, so he put together a good write-up on developing python for the device. Since the GPS unit takes up the com port previously used for debugging info, he added a hardware python debugging board to speed development.
