Custom EBike with a 200+ km range
[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?
[Andrew] and his brother had some time (and a lot of ping pong balls) on their hands, so they decided to have some fun and built a remote-controlled ping pong ball turret.
Arduino aside, the turret is cheap and easy to build as [Andrew’s] writeup explains. The firing mechanism was constructed using a pair of foam wheels and motors, which is used to launch the ping pong balls much like a baseball pitching machine. The balls are stored above the wheels in a cardboard tube and released by a mechanical flap when triggered.
When [Andrew] is ready to release the turret’s payload, he sends a command to his computer over VNC, which relays the command to the Arduino over a serial connection, triggering the flap. While the control scheme could certainly benefit from direct, wireless phone-to-Arduino communications, it seems to work well enough for [Andrew's] needs.
Check out the video dramatization below to see [Andrew] “surprise” his brother with a hail of ping pong balls after the jump.
[Justin N] sent in one of his projects. It’s a digital dashboard gauge for his Subaru. It’s built around an arduino board with a text LCD and standard automotive senders. He’s using it to monitor oil temp, turbo pressure, temperature, acceleration and provide a lap timing. The details are buried in this forum thread, but its worth a look if you’ve spent time geeking out on your car.
Here in the Midwest it sometimes seems like Spring will never, well…spring. We get that “April showers bring May flowers”, but nearly all of the last month has been cold and rainy around these parts. While things are improving, we think it’s always good practice to have a few fun projects at the ready, just in case your plans with the kids get rained out.
We think that Hackaday reader [Dombeef’s] papercraft strandbeest is a perfect idea for a rainy afternoon. The supply list is pretty short, requiring little more than some scissors, pliers, paperclips, and glue in addition to the thick paper that makes up the body of the strandbeest. The paper is cut into pieces according to the PDF template he includes in his Instructable, secured to one another via small pieces of paperclip.
Once the legs are all constructed, a main axis is built from one of the remaining paperclips, and everything is joined together under the main portion of the strandbeest’s body.
As you can see in the video, the legs work quite well, though the strandbeest can probably benefit from a hand crank in the short term. [Dombeef] plans on adding a small motor to his creation, which should get the strandbeest moving about quite rapidly once completed.
If you are looking for more fun projects to do with the kids, look no further than this papercraft gyroscope or these squishy circuits.
TomTom already runs Linux. The OpenTom project has documented the TomTom hardware and software to allow custom software builds to run. The Wiki covers everything from build tools to hardware connections. So far, a mp3 player has been released using the build tools. Hmm, I might have to pick one up to develop on myself. Thanks to [kniVes788] for the tip.
