#6 is a small, easy to build, inexpensive, bare-bones computer. Like the Arduino, it was designed to easily teach art students about microcontrollers, interactivity, and electronics. It’s only $25 (cheaper than the Arduino) is open source, and uses open source software for programming. It uses a very popular chip (AVR) so there’s a good code library available for it.

Once again, the Trossen Robotics Community came through with some amazing ideas. This is our fourth contest we have ran and are very excited to announce the winners of this round’s Trossen Robotics contest. This time around, we extended the deadline and upped the prizes. In case you’re new to the Trossen Robotics Community (TRC), here’s a quick overview on how this contest works:
A wide range of talented and dedicated people come to our Project Showcase forum to show off a project they’ve been working on. Periodically, we, the Trossen Robotics team, sort through these projects, and score them very “scientifically” in the following categories:
- “Wow” factor
- Presentation (graphics, videos, documentation, explanation, etc.).
This round ended up being the toughest yet on voting. There were soo many incredible projects from community members. We run this contest to help promote and encourage innovation and ingenuity. People are allowed to submit a wide range of projects ranging from robotics, automation, art, RFID, DIY, mods, inventions, and anything else demonstrating some form of technological creativity.
Read all about the winners and their projects in our Blog: If all goes as planned, the next contest (which is already underway) will conclude at the end of May 2008. You can stay up to date on contest rules and regulations at the Trossen Robotics Project Contest page , and start posting your projects in our Project Showcase Forum.

Rechargeable batteries is a good idea, but charging them is sometimes a lengthy process. This DIY battery charger could solve that problem. The charger has several safety features, including protection from overheating, and is well documented. [via]

This is the second version of the AVR signal generator. This time it uses a single sided PCB to simplify the project, and has both offset and amplitude controls. All the source code and schematics are available on the website. Signal generators can be very expensive, this version shouldn’t break the bank. [via]

this DIY project you can record earthquakes from around the world. This is a well-documented build, but you will have to purchase some software to interface with your seismometer. This site is a good place to start your amateur seismology and research. [via]
The following papers contain descriptions of a seismometer sensitive enough to detect and record earthquakes from around the world. It can be built using readily available parts from your local hardware store and from any general- purpose mail-order electronics supplier.

PCFILT is a serious filter design program written without useless “eye-wash”. Don’t expect it to look as pretty as the big-name brand software, but do expect it to design virtually any filter you need very quickly! PCFILT is loaded with powerful features that may seem hidden at first. This is for a good reason. With a little prompting from us you will be surprised at its flexibility. You will see why the largest filter company in the world has 60 (Yes, SIXTY) copies of PCFILT in use! PCFILT is also quite easy to use, but we can’t expect you to know how to use it right away. When you have the demo running, call us for a guided tour of PCFILT over the phone. This is the only way to know why PCFILT is used by people who are serious about designing filters! Demo version available.

SerReg is a small home controller intended to turn your personal computer ( PC ) into a process control / data collection system. With the appropriate sensors SerReg can monitor physical variables such as pressure, temperature, light intensity, weight, movement etc, process the information and then use the result to control up to three physical devices such as motors, heaters, sirens, lights or other appliances around the home, office, laboratory or factory . You can program your appliances to operate automatically in conjunction with your weekly and daily schedule, manualy turn them on/off from your PC or use SerReg as a process ON/OFF controller to regulate some kind of physical variable to the desired value.
