“My idea was to use an oscilloscope as the video output device to show some vector graphics, and create a mod player to provide the audio. The video part of the project had some design flaws and terrible noise in the DACs so I never really finished that part. Also, the audio part was much more fun. The modplayer was built using an ATmega325, a 4MBit flash memory and an op-amp to amplify the audio.”

“For the past two days I have literally lost my patience with Qik 2s9v1 dual serial motor controller. I have referred so many website and I could not make this controller work. After hours of searching I found this library which was compatible with Arduino 1.0…..Once that got the issue resolved I jumped into controlling the motor using a Proximity Sensor.”

“So I’ve done persistence of vision displays before; there’s really nothing new there. The challenge this time was to make it small enough to fit on a 72mm longboard wheel, and to make it cheap enough so that I could mass produce it and sell it to folks in the area.”

“What if you had the audio control panel, the dialog in most PCs where you fiddle audio, right next to your PC in physical form? With analog controls, VU meters and input/output selection present for instant access on your desk, you will have the pleasure of controlling them by hand.”

“This project provides a general purpose library which implements read and write support for MMC, SD and SDHC memory cards. It includes: low-level MMC, SD and SDHC read/write routines, partition table support and a simple FAT16/FAT32 read/write implementation.”

“The i2c-tiny-usb project is an open source/open hardware project. The goal of i2c-tiny-usb is to provide a cheap generic i2c interface to be attached to the usb. It is meant as a replacement for those simple and cheap printer port to i2c adapters. A USB solution has several advantages incl. the built-in power supply and a more future proof interface.”

“Make your X-Y capable analog oscilloscope more useful! Your oscilloscope can do a lot more using the Dutchtronix AVR Oscilloscope Clock.”

“This project describes an open software open hardware pH meter using an Arduino/Freeduino board. In other words, this is an electronic circuit to be connected with a glass electrode pH sensor.”

“A pixel artist friend of mine wanted a mouse to try his skills on a real C64. I thought I could help him by making an adapter that would allow a regular PS/2 mouse to be used with a Commodore 64. The most popular and supported C64 mouse is 1351 mouse which uses analog capabilities of joystick control ports to send movement data.”

“Sometimes I just get this idea in my head, and no matter how stupid or impractical it may be, I’m not going to stop until it’s done. …so I figured it was time for a gratuitous display of silly engineering. And with that, I’m quite pleased to present the world’s first overclocked, liquid cooled Arduino :-)”
