Steam Powered Tank

March 12, 2010 by Mike Szczys 38 Comments

This steam-powered tank is really something of a steam-electric hybrid. Steam provides the locomotion, but an electrical system provides the remote control and steering. A full boiler will provide 10-15 minutes of operation which you can see in the video after the break. Before you leave a nasty comment: Yes, we realize this project is from several years ago. It’s new to us and the completion date doesn’t diminish the novelty of this well-executed build. This is the quality and uniqueness we’re used to seeing from [Crabfu].

Sponge Music

[Aaron] calls this project “Stochasticity”. It uses two sponges as a musical interface. The performer wears a wrist strap and then draws on the table with water from the sponge to play different notes. You really need to watch the video to fully understand what’s going on here.

We’re guessing that this is Arduino based since some of his other projects are as well. You can try out another quick project of his, an Arduino electromagnetic field detector. Check out video of that after the break.

DIY Scratch Controller

There’s something viscerally pleasing about simple solutions. [Kip] came up with one in the form of a scratch controller. The spindle from an optical drive is used to hold a CD in place, which acts as the LP for scratching. The sensor from an optical mouse is mounted upside down below the CD and detects the rotation of the disc. From there it’s just a matter of setting up your software to get the reading from that mouse. He’s had some trouble finding disc surfaces that the mouse sensor will read reliably. We’d recommend trying some of those stick-on inkjet CD labels.

This is similar to a scratch controller we saw in 2008. That one was actually repurposing the IR encoding from inside of a mouse. We’re not sure which method would work better, but either controller will make a nice addition to a Flexi Knob setup.

Update: Nintendo DS Camera Control

March 11, 2010 by Mike Szczys 14 Comments

All of the juicy details needed to control a camera from your Nintendo DS are now available at the Open Camera Control project. This is the descendant of [Steve Chapman’s] setup from a few years ago. The system has been polished up and has seen many feature additions. It’s been used in movie production and works with a wide range of cameras.

Start by building your own interface cable using an AVR microcontroller running the Arduino bootloader. Finish up by loading some open source software onto the DS to add a cornucopia of shot options.

Hardware Jailbreak Eases Reboot Pains

March 11, 2010 by Mike Szczys 43 Comments

This device can jailbreak an iPhone. It doesn’t require a computer and it can either reboot a phone that was one-time-boot jailbroken using the blackra1n exploit, or jailbreak a factory fresh unit. We wouldn’t say this solves the tethering problem caused by blackra1n (needing to return to a computer to reboot the phone), but it certainly does ease the pain. We saw some info about the board layout but no parts list or firmware. See the demo after the break and leave a comment if you have more information on the parts or code.

Coffee Powered Car-puccino

March 10, 2010 by Jakob Griffith 44 Comments

We can only imagine how amazing this coffee burning car smells at it speeds down the highway at a maximum of 60mph. Don’t jump out of your seat so quick to get your own, while the idea sounds fantastic, the mileage will bring you back to earth rather quick. At 3 miles per kilo of coffee, it can turn that £36 210 mile trip into one between £910 and £1,820 with a stop to re-bean-fill every half hour!

Still, the Car-puccino is an amazing conversion, and we’re getting closer and closer to Back to the Future’s Mr. Fusion

50MHz To 100Mhz Scope Conversion

March 10, 2010 by Mike Szczys 96 Comments

[Ross] is the proud owner of a 50 MHz Rigol DS1052E oscilloscope. He’d like to have the 100 MHz version but the $400 difference in price puts it out of his reach. After some extensive poking around on the PCB and pouring over datasheets, he managed to reverse engineer the design and upgrade to a 100 MHz version. This is as easy as desoldering one capacitor to deactivate a high-pass filter present in the lesser model of scope, unlocking the faster potential of its bigger brother.
