Shovel…guitar?

September 4, 2010 by 53 Comments

We didn’t believe this hack at all when we saw it, or rather heard it. Surly a guitar made out of a shovel couldn’t sound decent. But the video (after the jump, skip to 2:40 for the jam) to our untrained ears sounded pretty rad. Could be the supremely well done wood work, proper use of tools, high tech pickups, or maybe Russian magic, we don’t know.

In fact, if you continue the video it doesn’t stop there. The creators also made a 2 string bass and a few other instruments from shovels. Do I smell a new shovel hero?

C Sharp Development 101 – A Tutorial Series

September 3, 2010 by 107 Comments

In this tutorial series we are going to look at C# Development using the Visual Studio 2010 Express editions.  This will take you from the basics of installing Visual Studio 2010 Express, to the Object Oriented Programming style associated with C# and other languages, dabble in some database access (Access & SQL Server Express) and finally, design a project that will pull all of our knowledge together into a final solution.

The Spindicator

oooh shiny

[Harvey] wrote in to share the Spindicator with us. The spindicator is a hard drive activity activity indicator built in a ring to resemble a dekatron. Using the pulses from the hard drive activity LED, [Harvey] tested several different methods of interpreting that data for display. The final version, negative edge triggered with a lowpass filter can be seen after the break.  It is nice and smooth and vaguely reminiscent of many programs’ loading screens.

He has pictures and tons of detail on the project including videos of previous versions that acted quite erratically.

EEVblog Dissects A Kindle 3

September 3, 2010 by 26 Comments

guts!

[Dave] over at the EEVblog did a review of the kindle 3 recently, but never got to the good stuff, the guts.  He is now rectifying this with a full video dissection of the eReader. Full of details on how to open it up as well as specifics on the internals, this is a fun video to watch. One thing that caught our attention was the RFID tag on the inside of the case.  It is probably for inventory tracking, but we can’t help but have a few tinfoil hat type thoughts. You can watch the video after the break.

Controlling The Power Of A Flash With A Tv Remote

September 3, 2010 by 8 Comments

For those who do fancy photography, setting up the lighting ends up being one of the larger tasks of each session. There are flashes out there that can be controlled via a remote control to help ease the process, but they can cost a considerable amount more. [Dsvilko] shares with us a fairly simple circuit that allows you to use a tv remote to control your flash. He’s using a picaxe 08m and he states that before this project, he had never messed with microcontrollers. We say great job on your first microcontroller project. You can catch a video of it in action after the break.

Trossen Robotics Holding Another Contest

September 2, 2010 by 7 Comments

3rd place doesn't really shoot lasers that make stuff blow up.

You have until December 1st to get your entry into the Trossen DIY robotics contest. Unlike the last Trossen contest we told you about, this one has no clear theme. The goal is simply to make an awesome robot. Registration is free, and entries will be judged on Ingenuity, Originality, and presentation/documentation. There are prizes for 1st, 2nd, and 3rd places, with the 1st place prize being the Interbotix Hexapod. If you haven’t seen it yet, it is a kit of a hexapod that is pretty quick on its feet. You can catch a video of it after the break.

Using An NES Controller On An Android Phone

September 2, 2010 by 20 Comments

[Sk3tch] rigged up a way to use an original NES controller with Android. He bought the controller and a breakout board for it at DEFCON. By combining the controller, an Arduino, and a blueSMIRF BlueTooth module the controller can be used as a keyboard on his Android device. In the video after the break he demonstrates pairing the devices and playing Super Mario Bros. 3 in an emulator.

He calls this Alpha quality but it certainly looks like it works well. In the beta version we’d love to see all of the extra electronics inside the controller case like those USB mods.
