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.
Propeller Based UAV Helicopter
I guess we’re on a UAV kick – I ran across this one when I was looking for interesting propeller projects. [Glenn]’s building this one based on a R/C helicopter he picked up. Both the controller and the heli recieved a propeller chip, along with a pretty standard array of navigation sensors for the heli. It’s a work in progress, but sometimes those are the most inspiring.
VUFan – VU Meter
This hack isn’t really all that, but I’m giving it points for creativity. [Christopher] pulled some blue led case fans and used them to make a giant VU meter. Each I/O line has a transistor to drive a TIP120 FET. Personally, I’ll like to see even more of them stacked end to end and pulling fog from a conduit placed behind the stack.
IR Helicopter Tracking
[Lyle] sent in some of his work with mini-copters. This rig was built to test control methods with his mini-copter UAV. I’m hoping that some attention here will get him to document a bit of his home testing for us. (He’s working on some bigger systems professionally, so I’m not sure if he will.) The test rig uses an IR camera to measure pitch, yaw and three dimensional positioning 120 times a second.
Solid State Amp (with Style)
[Jesse] sent in this beautiful 300 watt amp project. It uses six LM3886 amps to create a pair of 150 watt amps that are bridged to create a single 300 watt amplifier. Usually I don’t mind my lack of multi-language ability, but many of the parts were sourced from this site. It looks like the cases were bought in Hong Kong, anybody know were I could get some in the US?
Movie Screen Mask Controller
I was looking for some ideas for one of my little projects, and I ran across this screen mask controller that [Danny] was working on a while back. The roller drops a mask down, and an optical encoder lets the controller know the position of the mask. The final version is supposed to support ethernet, but I couldn’t find any updates on the project.
