A couple of readers weren’t too thrilled when the winners were announced a while back for the Nokia N900 competition. And to be honest, we even wondered on some ideas (like what does skateboarding have to do with hacking?) However, The teams have been hard at work and a picture video is starting to form for each. Check after the break for some video recaps.

What allows the everyday user to tinker with microcontrollers, IO, interrupts, serial communication, and even analog readings? How about individual modules that add the ability to communicate over bluetooth or add LCD support? If you were thinking Arduino, you would be wrong. It’s actually [Nilok’s] Qube, which at first seems like another Arduino clone however the Qube is based on PIC – not AVR. Another difference is the sweet black anodized case the Qube is planned to be put in.
While all this seems amazing at first, there is of course a catch – it looks like the first models are pre-order only for staunching price of $70! Sorry, but Arduino wins at half the cost.
Regardless, [Nilok] has documented the entire process and it’s amazing to read through; he even includes some guides on solder paste and bootloading USB. And who knows, maybe he’ll release open source. His site seems a little slow, we recommend the Google Cache.
[Jerry] retrofitted a Supermax Mill that he purchased from a friend. The main problem consisted of the original controller failing so he used some Pixie boards and a PC to get the system back up and running.
But thats not all. [Jerry] also retrofitted his Monarch lathe (yes, not a CNC, but are you really going to complain) by replacing the original Ward-Leanard motor generator with a 2 kW brushless AC servo.
The Harford HackerSpace group claims their CNC can kick any other CNC’s butt! Currently it lifts up to 65 pounds, but is still accurate enough to make ninja throwing stars. The only problem left is naming their CNC, any suggestions?
[Ciric] has finished up the hardware side of his CNC project. However the software is still being worked on, but because it is his own stepper control board it might take a while. The good news is the controller and software are planned to be released free.
[Rp181] is at it again with version 2 of his rail gun project (link dead, try Internet Archive). The original did have some power with 18 400V 3900uf capacitors, but he’s ramped it up to now using 40! Reaching more than double the amount of joules of energy, 12kJ vs. the 5.6kJ! Some other changes include a new injector solenoid setup and revision 3 of his breakwire chronograph. Sadly, he doesn’t mention if this is as green as his first rail gun. Check out a video of just the injector firing and an animation explaining some new updates after the jump.
When we introduced you to the Twitter Christmas tree ornaments, sadly we had very little information about the project. Luckily [Rob] made contact and clued us in on the inner workings. It even turns out we were wrong about the usage of Arduinos! We invite you to check out all the juicy inner workings after the break.

We asked for CNC projects, and wow did you guys deliver!
First up is [J-J Shortcut’s] MDF based CNC. He’s made three thus far, with the most recent costing about 180 euro and taking 2 months to build.
[Qwindelzorf] has also constructed a multitude of CNC machines including this industrial size router and this smaller miller.
Finally, [Mick’s] large steel CNC which just made its first cut only a week ago!
Keep up the great work guys, CNC machines are not easy to build and your accomplishments are ones for the record books.
[YB2Normal] has updated his steadicam 5 times! For those that remember the original, it allowed indie film makers to create smooth and steady video. Version 2 implemented a new gimbal based on a throttle linkage in cars. Version 3 allowed the user to easily adjust angles and weights to prevent accidentally knocking the assembly. Version 4 seems to have disappeared. And finally, version 5 updates the gimbal again using a Traxxas U-joint and redistributes the weight. What should come next? We think a handle, holding onto a threaded bolt can’t be good for your hands.
[Thanks Update]
