Hey Man, You Seen My Turntable Around Here?

January 1, 2010 by Mike Szczys 8 Comments

It’s all fine and dandy to have a turntable that sounds great, but [Mike] wanted one that looks great too. He build the transparent record player above and loved it for a little while. When his interest in it waned he built another, then several more. They all have some element of transparency to them, and each is a work of art. Makes us wonder how often he needs to dust his house to keep them looking so good.

Is turntable technology too advanced for your tastes? You can stick with your Edison cylinder, we won’t make fun.

[Thanks John]

Making A Rail Gun (again!)

January 1, 2010 by Jakob Griffith 24 Comments

[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.

TI-nspire Hacked

December 31, 2009 by Mike Szczys 17 Comments

The regulars at the United T1 forums keep them coming, this time hacking the Texas Instruments Nspire graphing calculator. We enjoy seeing the exploits that unlock the backend of these types of devices. The difference this time is that the hacking continues even though Texas Instruments has shown that it intends to protect the security of their devices using the DMCA. The Nspire thread linked above discusses the DMCA concerns just a bit but it seems obvious to us that running your own code falls under the umbrella of the act. The exploit package hasn’t yet been posted, but if you want it make sure you check back regularly before the take-down order comes in from TI.

[Thanks Iceman]

Trailer Side Indicator Lights

December 31, 2009 by Mike Szczys 29 Comments

[Imsolidstate] is working to add side turn signals to a trailer. These orange clearance lights are illuminated when the vehicle’s headlights are on to increase a long trailer’s visibility. They also blink along with the turn signals on the back of the trailer. A standard 6-pin lighting harness doesn’t support this functionality so the trick is to add them without altering the towing vehicle in any way. He’s using an ATtiny24 microprocessor to interpret the logic from the vehicle and then translate the turn signal and tail light data into a signal for the additional side indicators.

Meat Smoker From 55gal Drums

December 31, 2009 by Mike Szczys 28 Comments

[Joel] wanted to use his newly acquired welding skills to make something useful. With tasty flesh in mind he put together this meat smoker. What resulted is incredible, but the fact that he then gave it away as a gift is just amazing.

A curved joint between two pipes is known as a ‘fish mouth’. They can be a hassle, as with the pirate wheel project, but [Joel] used his noggin to make things easier. He first modeled two 55 gallon drums in CAD. The intersecting curve was then generated by the software, printed out on paper, and stenciled on the drum to be cut out with a jigsaw.

[Joel’s] writeup is greatly detailed and shares many pictures. He makes every part of this smoker, including the wood handles and the stainless steel grates. The guy really knows how to build stuff, but we should have known that after seeing the Crushtoberfest.

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.

Twitter Based Christmas Ornaments Update

December 31, 2009 by Jakob Griffith 2 Comments

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.
