Over 150 projects made from scrap parts (translated) have been posted for your viewing pleasure. They make up the entries in the “Make fast the scrap” project from c’t magazine. We already looked in on a toilet paper printer, but there’s a ton of other fun stuff to look at as well.
Every time you load the link at the top, the page picks a different set of entries to display. You can click through all the pages, or reload to play a little project roulette. The image above shows three that caught our eye. To the upper right is a lighbulb-man riding an old computer mouse reverse-cowgirl style. Quirky, but anyone who has access to an electroplating setup can get away with making simple objects like this into awesome desktop sculptures.
Moving clockwise we have a tiny USB drive mated with an old vacuum tube. The machine translation is a bit rough, but it looks like the LED from the thumb drive gives the tube a bit of a red glow. We just think it’s interesting to carry around a vacuum tube with you.
The final banner image shows a gyroscope for a camcorder. This is an awesome setup, which you can see in action after the break. A pair of broken hard drives provide motion stabilization for a camera. The entire assembly has a handle on the top with a universal joint. When the drives are spinning, the platform holds very still, even if the operator is swinging the unit around wildly.

[Thice] wanted to try his hand at incorporating a USB driving into other devices. He chose to add storage to his USB mouse but didn’t want to alter the factory look provided by a color-changing LED inside. To make things fit he ended up cutting a good portion of a USB hub’s circuit board off and placing it beneath the mouse circuitry. You can see the board from the thumb drive wedged into one end of the case in the image above.
He sees this as a way of hiding data in plain sight. This is true, and it’s along the same lines we’ve seen before with a WiFi dongle in a mouse, or the thumbdrive in a controller hacks. To be truly hidden we’d like to see someone incorporate a microcontroller that monitors the mouse buttons for a certain code, and then toggles the voltage to the USB storage. This would simulate plugging and unplugging the drive, hiding it virtually as well as physically.
Since the adoption of Kernel 2.6, Linux has used the udev system to handle devices such as USB connected peripherals. If you want to change the behavior when you plug something into a USB port, this section is for you. As an example, we will use a USB thumb drive but these methods should translate to any device handled by udev. As a goal for this exercise we decided to create a symlink and execute a script when a specific thumb drive was loaded. The operating system we used for this exercise is Ubuntu 9.04 Jaunty Jackalope.

We were expecting eye gouging and body slams, but this review of several thumb drive Linux distributions will do. They compared Damn Small Linux, Puppy Linux, Xubuntu, and Fedora. They don’t mention why they chose these four specifically, as UNetbootin has many many distributions available. They put each through its paces, listing common issues and boot up speed.
Their conclusion was that puppy Linux was preferable as it has a graphically nice interface and the ability to have persistent data storage on the disk. They have a poll going though, so head over and voice your opinion.
