Fresh from the tips line, [Pedro] sent in his GSM alarm. He combined a GSM phone, a motion sensor and BasicX24 controller board. If the detector trips during a set time period, the alarm sends SMS messages to the terminator, er whoever you want. He was kind enough to release the code, but I’d like to see this with a smaller micro-controller board to keep the cost/size down.

ATLAS Powered Rope Ascender Gen 3
This last weekend we got a chance to check out ATLAS Devices‘ latest version of their powered rope ascender. You probably saw their first generation device in the news earlier in the year. It was originally built for a design competition, but they’re now on generation 3. The earliest version used a capstan style winder, but newer versions have a far more simple/elegant design. The original had a ton of thrust and needle bearings that were hard to keep in adjustment. The new design is lighter, less abrasive to the rope, and easier to use.
Free Your IPhone
I wasn’t going to post this – it’s a freakin phone after all. But I’ve gotten quite a few tips on it, and I’d like them to end. [George] made a concerted effort to hack the iPhone – and it paid off. After his crazy ebay auction that topped out at 99,999,999.99 last time I checked, he ended up trading his first phone for a Nissan 350z and a few more iPhones.
He documented his process, step by step – if you’ve got the skills, you can probably do it yourself. The soldering work is damn fine work – probably the hardest thing there is. The write up is a little hard to follow, so plan on taking some time to comprehend everything. (Blogging software isn’t the best way to organize how-tos, trust me on this.) My hats off to [George], he did some great work. – So, why didn’t I want to post it? All this work yielded one thing: carrier choice for the iPhone.
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!
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.
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.
