This is a simple temperature sensor hooked up to some wireless transmitting equipment so that temperature can be monitored remotely. It uses atmel power for all the processing and standard rf radio modules. Software & Hardware schematics are available for download!

The Weeboy is quite the spin-off of the Wiimote. It uses an accelerometer to detect tilt and has a built in game around this sensor. This means, no joystick or gamepad, only a box that you tilt in every which way to play the game. Software & hardware schematics are available for download.

Snake robotics is a relatively new idea, however really cool. The implementation can be tricky but the overall design is actually not very mind-numbing. Each link in the snake acts as a single actuator (this project uses a servo) and helps to move the entire body of the snake. The project write-up has the purely analog electronic design and schematic.

This is a cool little robot with a very straight forward and simple design to be controlled remotely. It uses “off-the-shelf” circuitry and the project write-up has all the schematic and software info necessary for building your own. This project is light on the software, which makes it better for beginners, check this one out!

Unfortunately for today’s project, there were too many projects & only in pdf format! Even so, there’s a link to the index with 10 really good projects & write-ups. They use various electronic components and you can learn a lot by attempting to reproduce the projects. Take a look, give it a shot!

Here is another hand-held g-meter not terribly dissimilar from my own. The design uses an AVR microcontroller and is designed for a small area. I really liked the code work & hardware design for this project. Don’t miss this one!

This little homemade hand-held console uses an arm processor for everything. A nokia lcd screen displays the output for the game & there’s a few buttons for input. Looking at it makes me really see how simple the gameboy must have been to design (or would be with current technology). The write-up has all the hardware & pcd layout information listed.

The project write-up for this robot is very thorough and even the newest of the new can build this bot. The author’s write-up style is similar to mine except it’s all on one really, really long page (pro or con, I’m not sure). Be sure to check out the video of it in action!

We previously covered the Zephyr Solar Powered UAV on PyroElectro and it’s back already. Just this sunday the UAV flew nonstop for 83 hours and 37 minutes. It used rechargeable batteries for flight during the night. Both articles are linked below.

We’ve seen a few of these before but this mobile iPod battery pack is definitely the simplest. It just uses two 9v and two AA’s. This method could potentially (but unlikely) be harmful to your iPod since no control circuitry exists, but it’s doubtful anything bad would happen.
