Nexus One Rooted

December 31, 2009 by Mike Szczys 16 Comments

You know it’s getting a bit ridiculous when hardware that hasn’t hit the streets is being rooted. That’s exactly what has happened, root access can now be achieved on the Nexus One. [Paul] found an exploit and packaged it nicely so that anyone can do it. We do wish he had shared the details of the exploit but we’re not complaining.

If you’re not in the know, the Nexus One is the fabled Google Phone now come to life. It’s slated for release in 2010 and some think that will be officially unveiled at a January 5th press conference. That’s right, unveiled. The device has been cracked yet it doesn’t officially exist. What it does do is join a growing number of rooted android phones.

Pinball Build Throws Down The Gauntlet

December 31, 2009 by Mike Szczys 10 Comments

[Jeri Ellsworth] is building her own pinball machine. Her build log is delivered in the form of daily videos that walk through the progress. In addition to seeing the intricate ramps, traps, and controllers she outlines her build techniques. These include reproducing parts based on old pinball machines and bending acrylic with a custom tool or a toaster oven.

The driver she’s planning to use is an Altera FPGA with a bunch of FETs to control the heavy-load components. There’s not a ton of info on the actual electronics but we had a heck of a fun time looking at the creative field components. Our favorite by far is the television from Day 7. The screen is translucent with a rear projected image. When the ramp in front of it is raised the pinball can be jumped right through the screen!

We couldn’t find a project page for this but we’ve embedded [Jeri’s] videos after the break. Continue reading “Pinball Build Throws Down The Gauntlet” →

CoffeeScript: Like Aspirin For JavaScript

December 31, 2009 by Mike Szczys 23 Comments

CoffeeScript is a language that compiles down into JavaScript. “But why? JavaScript is so simple?” Bullcorn.

If you don’t use JavaScript everyday the language is wonky and frustrating. When you need quick snippet of Javascript to build into a page you may know how to do it with three or four different languages but struggle with the touchy syntax that has long given developers headaches.

Give CoffeeScript a try, you’ll like it. If you do, give them a hand with development too.

Update: Realtime 3D For You Too!

December 30, 2009 by Mike Szczys 25 Comments

[Kyle McDonald] has kept himself busy working on 3D scanning in realtime. He’s posted a writeup that takes us through the concepts, tools, and assembly of a DIY 3d scanning camera. You should remember a preview of this method posted earlier this month, but now it’s time to build your own. You’ll need a camera, a projector, and some open source software to process the image data. Using these simple tools, [Kyle] turned out much better video than before. Take a look after the break to see his results from scanning at 60 fps using a PS3 Eye. The trick to this setup is getting the correct synchronization between the projector and the camera, something that could be improved with a bit of extra hacking.

Does [Kyle’s] name sound familiar? It should, he’s got a long history of quality hacks that we’ve featured over the years. If you’re looking to use a scanner as a multitouch, add some music to tea time, or play with your skittles his work will give you a shove in the right direction.

RFID Meets Open Sound Control

December 30, 2009 by Mike Szczys 6 Comments

Have you been working on a MIDI controller that uses RFID to identify and control different instruments? No? Neither have we but now we’re going to have to look into it. That’s because [Martin.K] has done a lot of the work for us. His nfOSC package links an RFID reader to the Open Sound Control library.

In the video after the break we see [Martin] placing RFID tags onto a Touchatag reader. With each addition, his software triggers a tag add event that OSC picks up and translates to a midi event; in this case it adds a new instrument to the mix. Can this be used to relieve musicians from staring at computer screens during performances? What if there was a small shelf in front of you? As you happily play your electric Didgeridoo, small items with RFID tags on them can be added or removed from that shelf to change the samples that are triggered when toiling away on that sonic weapon. This should be fun!

Simplest Most Useless Machine

[Brett] posted about his most useless machine build. His project gives us a chance to massacre the language in the title because it uses the lowest parts count we’ve see with these machines. The logic is controlled by our friend, the 555 timer. Add to that just one servo motor, two switches, three resistors, two caps, a diode, and a battery pack and you’re in business. The hardest part to find locally is the servo but check at a hobby/RC store. If you don’t have to put in a parts order this can be your next impulse project.

UAV Reigns Down Vengeance Upon Thee

December 30, 2009 by Mike Szczys 55 Comments

An unemployed electrical engineer can be a very dangerous thing. [Cybrown] has turned his skills toward darker, more awesome applications by building an armed unmanned aerial vehicle. This is a remote control airplane that has a movable camera mounted in the cockpit. Video and GPS data are sent back to the pilot who views the picture via a wearable display. We’re betting this doesn’t have the range that the 100km UAV did, but that’s good because this one brings doom from the skies. Check the wings in the picture above, this RC is fireworks-enable. We’ve embedded flight footage and attack video after the break.

Update: Here is a forum post covering this nugget of awesome. There are just a few details but the entire thread is interesting. Someone pointed this out in the comments but they don’t get credit because they didn’t leave a link.
