Custom EBike with a 200+ km range

ebike

[Doctorbass] constructed an awesome electrical bike back in 2008 from a Mongoose bicycle. The bike boasts a top speed of 76km/h and a total range of 210 km on a single charge. Some car company needs to hire this guy STAT.

Build to order Xbox 360 laptops

[Ed] recently got his hands on a CNC machine and immediately constructed an Xbox 360 laptop. They look pretty sharp, and he’s willing to make a custom laptop if you are interested. We’re thinking someone needs to organize a contest between [Ed] and [Ben Heck].

A portable GameCube to rule them all

It’s no secret we enjoy portable console hacks around here, and this portable GameCube is quite the looker. Clearly a lot of thought and work went into this mod, and it shows.

Ultrasonic backup sensor for the parking impaired

If you decided not to spring for those backup sensors on your new ride, [Eric's] got you covered. He walks us through how he created an ultrasonic backup sensor using an Arduino and an add on programmable logic board.

Mega laser construction begins

Europe’s Extreme Light Infrastructure project is set to start building the world’s most powerful laser measuring in at 200 petawatts. Scientists are betting on the laser to be able to tear apart the vacuum of space and time itself, if only for a fraction of a second. Seems like a solid plan to us – what could possibly go wrong?

Help identify this vintage electronics component

[Windell] over at Evil Mad Scientist Laboratories has reached out in order to help them identify a mystery piece of electronics equipment they came across a few years ago. Discovered at an electronics surplus store, the mystery component looks like a cross between an over-sized chess board and a breadboard. Failing to identify it they eventually disposed of the board, snapping a couple of pictures for good measure before it was gone for good.

Recently while visiting a local electronics flea market, they came across what looked to be a similar, though much smaller board. This piqued their curiosity and compelled them to dig out the pictures of the mystery board in hopes of finally discovering what it was. Using markings on the new board they found, the team at EMSL located some images of a patchboard cartridge that looked quite similar to their mystery object. Upon closer inspection however, they think that the two pieces might be related, but are not quite the same item.

Swing by their site and chime in if you happen to have any good leads – we’re sure they will appreciate it.
