[Barry] sent in his writeup and video about a serious vulnerability in the AXA bike lock. (One of the most popular locks in the Netherlands.) It turns out that quite a few of them can be opened with a blank key. [Barry] demo’s the hack, and has some comments about the lame efforts of the manufacturer. If you enjoy interesting reading, check out his blog covering lock picking and physical security.

Cornell Final Projects 2007

The latest crop of final projects from Cornell Universities ECE576 course went up a while ago. This round focuses on FPGAs. They’re all fairly impressive projects. My favorite is this real time spectrograph. With the decreasing cost of FPGAs, this Digital Oscilloscope could become a popular one. Putting this UDP network stack on a capture the flag network would probably freak out some people. Lately I’ve noticed a trend of replacing ASIC chips with FPGAs – these projects could be just the thing to get some people started with them.
Day O’ Guitar Hero Mods (with A Bonus)

I’ve already gotten a pile of tips on Guitar Hero controllers today, so here we go. The first one is already making the rounds. [Mark] replaced strummer with a touchscreen LCD and a magnetic switch. [Mark]s ultimate goal is to add some optical sensing and make the guitar self playing. For details, hit the acidmods thread or just watch the proof of concept demo.
[Johan] sent in the second controller of the day, and it’s probably my favorite for guitar bling. The original mushy switches were replaced with micro-switches and CNC milled replacement buttons. Each button is individually lit with LEDs and a cold cathode lights up translucent panel in the body. A PIC controller controls the lights and provides some input options for button tapping. The video is actually pretty entertaining to watch.
For a little bonus, check out [Mastershake916]’s cast Hack-A-Day pendant.
Friday I Want A Ball Pit Extra

[rmunroe] of the notorious xkcd made his own ball pit. I’m now completely, totally jealous.
[-] sent in this Commadore 64 Guitar Hero project.
[Jock] sent in this uh, marriage of a Wiimote and a rocking horse. It’s actually a great idea if you’ve got a kid and some duct tape handy.
[warthox] sent in this XBox 360 tilt controller project. These have been popping up a bit, but you might like this one. The board is all surface mount, and was routed to make the prototype. I kind-of like the surface pads that were used to mount the wires to avoid doing thru hole mounts.
We’ve been digging the EeePC – [Paul] wrote up his tricks to get Ubuntu working on the thing.
[Jock] sent in this huge set of music hacks. Mostly circuit bent, but they make for interesting reading.
DIY SCUBA Tank Boost Pump (for Mixing Gases)

No love for that sweet old NES controller? Fine, here’s a bonus hack for you. This home-built boost pump is designed to take in a volume of gas (like oxygen) and compress it with a hydraulic style air powered cylinder to raise the pressure. With the increased pressure, the O2 can be added to a SCUBA tank that contains high pressure air to create what’s known as NITROX. The idea is to increase the percentage of Oxygen in order to reduce Nitrogen absorbtion in the blood – increasing a divers safe time at depth underwater.
The compression cylinder is built entirely of brass with Sirvon seals. The drive cylinder and 2:1 lever produces 3,000 lbs of pressure on the pump cylinder, all from 120psi of pressure from a standard shop air compressor.
Pen Size Polonium Detector

[cartufer] sent in this sweet little Polonium detector. It’s fundamentally similar to the Geiger counter the other day, but the circuit is simpler by several orders of magnitude. No exotic parts for this one, just some basic metal working skills. (This might be handy when I visit my in-laws.) The page is loaded with several ion detection designs, from simple to very complex.
Python Web Based Serial Control
[Benjamin] sent in his efforts to use Python to provide a web interface for his Aurdino. Python is usually pretty easy to manipulate, so it might be just the thing for someone looking to add a web control to a project with an open serial interface.
