LED And Fan Controller

Needing a front fan to keep his hard drive cool, [CalcProgrammer1] found he was unhappy with a single LED color for the fan. He swapped them out for a set of four RGB LEDs and whipped up his own controller board for the unit. It is based around an ATmega168 and patches into the COM2 header on the motherboard, providing a serial interface. [CalcProgrammer1] wrote a GUI to control fan speed, and individual LED color settings. You can take a look at and enthralling, edge-of-your-seat demonstration of how slider controls work after the break. Wouldn’t it be great if the HDD LED clock could be adapted to use a fan so that the front panel had a colorful analog dial on it? Continue reading “LED And Fan Controller”

Automatic Telephone Recorder

[James Bond] types and those suffering from a hefty dose of paranoia can now record all telephone conversations. [Trax] built this module that monitors the phone line and starts recording when a handset is picked up. A computer does the actual recording, triggered by the microcontroller via a USB connection.

We like the use of an old PCB for a faceplate, we’ve certainly got some duds of our own sitting around. The three cords are a bit confusing though. One for the phone line, one for the USB, but what does the third do? Is it an audio-out connection?

We’ve asked [Trax] to post a schematic and source code if possible so that might clear up the mystery.

Update: [Trax] let us know that there is a red button with white lettering at the bottom labeled “download”. This contains schematic, code, pcb layout, and PC software. We just missed it the first time around.

FanWing Is Like A Harvester In The Sky

The FanWing aircraft concept has been around for a while but this is the first time we’ve seen working models. It gets rid of the propeller and adopts a rotating cylinder for propulsion. The look reminds us of a combine harvester and in a way it does reap the air, pulling the craft through the sky. We’re not holding our breath for the decommission of jet propulsion in the wake of this method, but we’d love to see some fun-loving death from above whenever you can get your own off the ground. Check out the video clips after the break to see, and hear, this in action.

Hacking Space Without Profit Or Secrecy

Reader [Jacob] tipped us off about a project the aims to make the final frontier open source. The mission of the Copenhagen Suborbitals is to launch a man into space. What they’re not interested in is turning a profit, carrying hazmat or weapons, or keeping what they learn to themselves.

Surprisingly enough, isn’t this the next logical step after hobbyists send cameras into space? This team thinks so and they’ve been hard at work building and testing rockets. With the last round of successful tests behind them, they’ve paved the way for a launch of the first round of the campaign on June first. Da duh daaaah da duh duh da daaaaa

Smart Flash Synchronization

[Max] designed this circuit to add smart flash synchronization to his photography arsenal. He did this because ‘dumb’ TTL based flashes won’t play nicely with more sophisticated systems like the Nikon Advanced Wireless Lighting. By building a microcontroller into the mechanism, he’s added functionality for several different scenarios, ensuring that he’ll never again have problems with early flash triggering. Now that the kinks have been ironed out in the prototype, the code and hardware can be migrated over to whatever microcontroller suits you.

Steampunk Sequencer

[Moritz Wolpert] built this gem of Victorian hardware by hand. It is a sequencer and features beautiful detail work as shown in its MySpace gallery. Other than that we don’t know a lot about it. You can also take a look at [Moritz’s] main page, but prepare to be annoyed by the hideous web-styling that really undercuts the beauty of his physical product.

Hacker Finds Better Use For A Windows Machine

[Patrick Becker] had an ancient PC on his hands with a blown PSU. He converted this into a stylish home for his Betta splendens.

The aquarium itself is fashioned from a piece for construction glass block with the top cut off. This allows for a window that looks through the tank and shows off the motherboard on the other side. He patched into the AC connector so that the original power cord can be used to control the pump. A lighted pump button was added to the front panel and a fancy bezel fitted to the viewing portal in the side of the case. He finished off the project with a PVC pipe for air and food. His blue screen of death now features water and a real fish.
