The Outstanding AVR based SCSI RAM Disk is a project that created an universal SCSI controller. Very cool if you need a SCSI device for something, for example an old computer.

I bought a SmartQ V5 (I bought mine from DX). This small device have one interesting feature compared with other devices like this: it comes factory installed with three operating systems: Linux (Ubuntu), Android and WinCE. When you boot, you can choose which os to boot.

TEMPer - USB Digital Thermometer Dongle

The TEMPer is a low cost temperature probe. The deice consists of a usb-serial chip (WinChipHead, a 24xx02 serial EEPROM LM75 temperature sensor CH341) and a LED (the LED is connected to the thermostat output of the LM75). While the software that comes with the device is only for Windows, other solutions do exist. The first one I found was from Tollef Fog Heen's blog, then from Levien van Zon, and finally Stefan Boethke's TEMPer wiki page. The last one works nicely on FreeBSD 8.0-stable, using the uchcom(4) driver.

Petabytes on a budget: How to build cheap cloud storage explain how you can build network storage cheaper than most commercial alternatives. And the design is freely available. They even explain what software they are using. Very cool!

The Fabulous Logic Analyzer

Here is another interesting project: The Fabulous Logic Analyzer is a simple logic analyzer for the PC. This one consists of a simple schematic which is attached on the PCs parallel port (a real parallel port is highly recommended, not a USB adapter) and which can analyze H and L levels of 8 inputs. On the PC, there's running a graphical program which displays the contents. Supported platforms: FreeBSD / i386, OpenBSD / i386, Linux, Solaris / x86, Windows.

A Tiny 80(C)32 BASIC Board by Ronald Dekker is interesting. He built a small microcomputer wich runs basic (Intel MCS BASIC-52), just from salvaged components.

Zet - x86 compatible soft processor

Since I got myself an Altera DE1 board, I have been trying out as many FPGA implementations of hardware as I can find time to. Zet processor is an open implementation of the so widely used IA-32 architecture (generally called x86). Currently, only the 16-bit 8086/80186 work. But still it can boot MS-DOS 6.22 and FreeDOS 1.1. I testet Zet version 0.6.1 and followed the Altera DE1 Installation guide, booting from A: in flash. It was very retro to see MS-DOS booting from A: again. except for om screen misalignment, and a noise in the speaker, it worked fine.

Open Programmer - an open source USB programmer for PIC micros, I2C and MicroWire EEPROMs, some ATMEL micros, generic I2C/SPI devices and (soon) other devices. Quick facts:

Completely free and Open Source (including firmware)
Programs PIC10-12-16-18, 24xxxx I2C EEPROMs, 93SX6 MicroWire EEPROMs, some ATMEL micros, communicates with generic I2C & SPI devices
USB 2.0 Full Speed interface, HID class (same as keyboards, mice, etc.)
Self powered
Built from easy to find components (estimated cost ~10�)
Hardware generated timings for maximum speed and reliability (writes a 18F2550 in 15s, 8s under Linux)
Open source control programs for Linux and Windows

An oldie, but still: EEP: EEPROM Programmer for Linux: EEP is an open hardware design EEPROM burner for 24-pin and 28-pin 5-volt EEPROMs with Linux support. Cool if you need it.
