For all the wonder of dulcet tones coming from a century-old music box, we’ve got to admit that [Markus]‘ wavetable synthesis build is still pretty impressive. Of course, the Internet cred gained by doing a demo of Still Alive helps too. Wavetable synthesis stores a one cycle long waveform in RAM that can be played on a loop at [...]

[Markus] had been drooling over some LED panels to use as a soft light source for photography, but being a hobbyist, he didn’t want to spend a ton of money to buy them. He figured that he had enough electronics know-how to build his own panels, while saving a boatload of cash in the process. [...]

We can order seven segment displays in red, green, yellow, or blue all day long. One thing we haven’t seen is an RGB segmented display, so [Markus]‘ project is really interesting. He took a stock seven segment display and modded it into an RGB display. After taking a Dremel to the back of the stock [...]

When we first covered [Markus]‘ portable SID player we starting dreaming about an alternative universe circa 1987 that included a pocket-sized music player called the Commodore ePod. [Markus]‘ updated firmware that connects his SID player to a PC will have to do for now, we suppose. The new firmware boots the Portable SID player as either a [...]

[Markus Kayser] built an amazing solar powered SLS printer, but instead of using lasers and powdered plastics his machine uses the power of the sun to heat sand into complex shapes. [Markus]‘ printer uses the same concept as his earlier solar cutter – burning things with a magnifying glass. Interestingly, the printer isn’t controlled with [...]

[Markus] was looking to upgrade his soldering station, and having had good luck with Ersa in the past, opted to purchase one of their new stations, the RDS 80. Once he got the iron home however, he was very disappointed to see that while his previous Ersa model used a silicone cable to connect the [...]

[Markus] on the DangerousPrototypes forum came up with a great little SID player. The SID was (is?) the awesome sound generation chip inside the Commodore 64, and along with Game Boys and NESs laid the foundation for the chiptune scene. We’re happy to finally see a small SID player that doesn’t resort to SID emulation [...]

[Markus] had a TI MSP430 sitting around from the LaunchPad kit he bought a while back. He didn’t know what to do with it, but eventually decided that it would make a great miniature alarm clock. He added a shift register to the mix in order to drive his 7-segment LCD display, using two of [...]

[Markus] got his hands on a split-flap display and built a controller for it. These sometimes can be found on really old alarm clocks, but [Markus] was a lucky-duck and managed to acquire this large 8-digit display which previously made its home in a railroad station. They work like a Rolodex, mounting flaps around a cylinder [...]

[Markus] built his own reverse geocache puzzle box but on a smaller scale than the original. His is based around a PIC 18F2520 and powered by two AAA batteries. The user interface includes one button, a 16×2 character LCD, and a piezo speaker. The box unlocks itself when the GPS module inside detects the proper [...]
