Edison Cylinder Recordings Need More Cowbell

[Norman] spent three years developing and building his own Edison cylinder phonograph with electric pickup. We’re glad he did, and that he shared it with the world because the product is a thing of beauty. Every part is clean and precise with plenty of room for adjustments to accommodate differences in media. He’s reused the head from a VCR and attached it to a CNC machined polypropylene mandrel. The needle is interfaced with the cylinder via a delicate passively driven carriage. This consists of an aluminum rod with the cartridge at one end, and two wheels at the other. The wheels travel along a precision rod, propelled by the needle tracking the groove in the wax. Wonderful!

We’ve embedded a video of the device playing a recording of Sousa’s El Capitan from the late 19th century. Although familiar with these cylinder recordings, we were surprised by how little recording space there is available on one. Continue reading “Edison Cylinder Recordings Need More Cowbell” →

Ben Heck Gets Sloppy And We Love It

[Ben Heck] is a name synonymous with game system hacking. His projects have been seen and praised by people all over the world for both their quality and their ingenuity. He’s so good, in fact, that many of his projects have gone far beyond what we typically think of as hacking. They look and feel like commercial products. While that is a fantastic accomplishment, we have a soft spot for seeing stuff that is truly hacked. This lasted job he did is a great example. The controller needed to work using a single hand, so he hacked it. He was in a hurry, so it didn’t get his usual professional finish. We kind of like it that way. This one handed controller mod can be seen in action after the break.

Six Monitors, One Video Card

6 displays 1 videocard

With most of us utilizing at least two monitors these days in our day to day operations, six monitors, while an awesome thought, might seem a little too excessive. After all, do we really have space for multiple video cards?

AMD has a new setup in their testing lab that is running six Dell 30inch displays at 7680×3200 through a video card holding six DisplayPort connectors.

Maximum PC has the scoop on the setup, and they say that this single GPU will be coming out on AMD’s DirectX 11 capable chips. Details are slim with the amount of video RAM, speeds and cost not known at present.

Think of the possibilities! Trade shows are one thing, but how about a video wall at home for gaming and movies? How would you use the six monitors shown above? Be sure to leave your ideas in the comments.

Nixie Plasma Ball

This one came out over a year ago and we missed it. [Daqq] has made a plasma ball out of a nixie tube. All that was required was the transformer from a cold cathode meant for computers and a nixie tube. He did have to do a tiny bit of modification to the power supply, which you can see on the project page. This isn’t the most useful project, since you can’t really see much of the plasma, but it is really cool nonetheless. We think this would make a really neat button. You can see a video of it in action after the break.

Classy Hard Drive Speaker Set

Hard drive speakers aren’t anything new, but they have yet to be done very professionally. Most hard drive speaker hacks are awesome, but aren’t meant to be a showpiece. [Oliver] took the opportunity to put together a set of 20GB drives and a custom-built acrylic case with a horizontal VU meter up front. The project is well-photographed and documented and can be recreated without the use of laser cutters or other expensive tools. The only thing it’s missing is an iPod dock!

Tube Amplifier In A PSU

[Niclas] sent us his home made tube amplifier. For the case he used a computer power supply unit, took out the guts and replaced them with the amplifier board. He based this build off of an existing design but took a more minimalist approach. The wooden face plate has an on/off switch, an audio jack, and volume control. Apparently, the tubes are floating loose inside of the case. We’d recommend a more secure mounting method for these delicate parts.

Controlling An R/C Car With A Pic16F84

[GuySoft] sent in this project. He doesn’t normally mess with electronics, but decided to give it a try. He chose a fairly complicated project to be his first, but seems extremely comfortable with it. This project was to control his R/C car with a pic16f84. That chip was chosen simply because it was the only one available at local stores. Though we’ve seen much more complicated projects in the past, he does a great job of showing exactly what has been done. He shares his thoughts and source code with us as well. He has express a little frustration about the closed source compiler he was using, so if anyone has any suggestions for him, he would probably appreciate it. The funny part is that he mentions that people would just tell him to “get an AVR”. We think the readers here will probably be happy with how he pulled it off.
