The MIDI piano instructor is a tool aimed at those who wish to learn to play piano, but don’t want to take lessons. The LED bar mounted above the keys lights up to show you exactly what key to press and when. We’ve seen this available in some electronic keyboards for some time, but this unit would be able to fit any standard sized keyboard. Check the page for schematics and pictures.

This is the fourth generation MIDIbox sequencer which has a features set that’s several screens long. We’ve embedded the teaser video of this 16-track marvel after the break. You can use it via a traditional MIDI connection or with USB. Standalone Ethernet features are also in the works. It’s fully documented and you can etch your own PCB if you’re brave but it might be easier to get in on the group PCB buy if you just have to have one of these. There’s no all-in-one kit, but that will just make the taste of success sweeter once your soldering iron cools down.
[Alessandro Lambardi] had some vacuum flourescent displays that he pulled from junked VCRs. His latest project is an experiment to use one of the VFDs as a headphone amplifier (Wayback Machine Cache). This means he’s trying to use them as vacuum triode amplifiers, aka vacuum tubes. He did get it to work but as he suspected, the output is fairly low power. It may be possible to use this setup as a preamp and build an actual tube amp to use along with it.
Update: Thanks to [Fallen] for mentioning that we’ve covered this concept in the past.

The silent drum is played with your hands. It acts as a midi device by analyzing the movement of the rubbery black drum head. As you can see in the photo, one side of the body is clear and the other is white. A light shines up into it to boost the contrast and a camera picks up the black head as it moves past the white side of the shell. [Jaime Oliver] has provided an interesting look at the analysis method used with this instrument and there’s also a system of notating a composition for future performance. See and hear it played in the demo after the break.
Here is one that really got some of us at the HAD offices excited (yes, we own Zunes). The introduction of the Open Zune Development Kit. Sure, there was XNA, and we even toyed around with it. But anyone will quickly realize just how limited XNA is, especially with older hardware.
OpenZDK is in its infancy, with only one application thus far (don’t worry, you can still use XNA apps too). But we wanted to give it a shout out and let the hacker community make this potential into a reality.

There are cars that increase the radio volume as you drive faster, and video games that ramp up the music as your gameplay improves (we’re looking at you SSX Tricky). Now you can add that feature to your workout with [Polymithic’s] Motion Feedback MP3 Player. It uses a passive infrared sensor to detect motion so there’s no need to wear any electronics. But if you used some Bluetooth headphones you could bring the system with you to the gym, just don’t exercise so hard that you blow your eardrums out.

This video brought a smile to our faces. [Griffin Milsap] is creating live music using an orchestra of solenoid instruments. Each solenoid is set up to strike an object such as a bowl or mug. The trigger mechanism is a light sensor inside of a ping-pong ball. The collection of instruments is conducted by a motor-mounted green laser. When the beam of light passes by one of the ping-pong balls the photo transistor inside actuates the solenoid and a note is played. The pitches are quite a bit more random than the Robo-vibe, but it’s delightful to hear the results that [Griffin] has achieved.
