What is Ginger ? Ginger is yet another physical computing platform, which is similar to gainer (http://gainer.cc). The goal of project is to develop PC Platform
Ginger makes use of avr-usb (http://www.obdev.at/avrusb/) for the implementation of USB interface. Thanks to avr-usb, no external USB-serial bridge chip is required to interface host PC, and this makes ginger hardware simple. ATmega88 is chosen because it is available in AKIZUKI-denshi, where many electric parts are sold in bargain price.(We love the store).
In Macintosh platforms, you don’t need to install software drivers, as the device is recognized as /dev/cu.usbmodem*. In Windows, please use ginger.inf provided with source code in tarball.

This is the reconstruction of a “Fakespace GL-8001” device with fully compatible serial interface via USB. This device fits into a very small SubD adapter housing, consumes low power (max. 20 mA), supports USB standby, may support a USB remote wakeup feature later, is much faster in responsiveness than the GL-8001, and the electronic components are fairly cheap, lower than 5 €.

There are dozens of projects like this one on the web, but it’s nice to be able to chose the one you like most. Nothing special with this AVR ISP programmer, maybe just the idea that the author build it because hi’s hold programmer was working trough serial connection and as most modern devices work on USB he decided to make his programmer work on USB.
So, the solution was to replace the two transistors, that were used to adapt the RS-232 voltage levels to TTL voltage levels, with a USB to RS-232 chip such as FT-232BM.

If you’re looking for a build-it-yourself, standalone, USB harddrive based MP3 player, this may be of interest to you. Originally conceived as a replacement for a CD player, this unit sits on the shelf next to your stereo and connects via standard RCA line-out audio connectors. Features of the player include:
- Large, back-lit LCD display
- IR remote-control receiver port
- USB 2.0 connection for fast song transfers
- Functions as a USB harddisk
- 24-bit stereo audio out
- Support for fixed & variable bitrate MP3 files to 320 kbps
- Supports harddisks up to 137 GB
This is an open-source project. Full hardware schematics and software source code are freely available on the project site.

This project demonstrates how you can control a stepper motor over USB using a special software. The motor is driven by a PIC18F4550 running with full speed USB interface at 48MHz. The software for the computer was written in Delphi and the code for PIC was written in MPlab. The source files are provided so you can make any adjustments needed.
