In the never-ending pursuit of cheap wireless communication for your microcontroller projects, [kiu] came up with a small board that allows for serial communication via a 433MHz radio link. [kiu]‘s transceiver uses an RFM12 wireless module available online for just a few dollars. Alongside this module is an ATMega8 and a USB to serial FTDI chip. [...]

[Vinod's] latest project lets him use a TV remote control as a mouse. It may not sound like much, but he did it with a minimum of hardware and packed in the maximum when it comes to features. He’s using an ATmega8 to read the remote control signals and provide USB connectivity. With the V-USB [...]

We think it’s a bit to late to show up for a screening of The Avengers in full costume, but an arc reactor T-shirt would be pretty cool. [4ndreas] built a chest strap that looks much like [Tony Stark's] chest-mounted power source. It has a 3D printed enclosure which hosts the ATmega8 and 22 LEDs [...]

[Fezoj] likes to play around with microcontrollers and decided that he wanted to try a Bus Pirate as a new tool in his adventures. Since it’s open hardware he had his own board made and populated it himself. The trouble is, he works only with AVR chips and doesn’t have a PIC programmer. No problem, [...]

[jethomson] sent in a build he’s been working on that turns an inexpensive AVR programmer into a development board. The build is based on the very affordable USBasp programmer that’s based on an ATmega8. With hundreds of these boards available from China for less than a Hamilton, we’re wondering how soon it will be before [...]

[Niklas Roy] sent in a project he just completed called PING! Augmented Pixel. At first glance the entire build is just a plain jane retro video game stuffed into an ATmega8 but looks can be deceiving. The video game is actually an augmented reality device that inserts a pixel into a video feed. The bouncing [...]

[dunk] constructed an easy to use AVR-based USB controller with the ability to drive up to six R/C hobby servos at once.  While the USB-powered Atmega8 he used supplies the necessary PWM signaling for all of the servos, an external power supply rated up to 30v at 3A is necessary to provide the 5v of [...]

[Thomas Pfeifer] has taken the PPM signal produced by model aircraft wireless controllers, and with an ATMega8, converted the signal to act as a USB joystick. Which means you can now use a standard R/C remote control to fly model aircrafts on your computer. Of course now with PPM decoded you could also use the [...]

In this instructible, [wkter] takes us through the process of running a Nokia 3310 LCD display using an ATmega8.  This instructible isn’t a beginners project as he assumes you already have a strong understanding of how to work with these components and their programming languages. He is very thorough with information though, providing datasheets, pinout [...]

We love our AVR Dragon programmer but it can be nice to have a cheap and simple in system programmer on hand too. The USBasp is one such programmer that uses and ATmega8 as its only IC. It requires just a handful of components and can be purchased as a kit, or etched and assembled [...]

If you’ve ever spent time working with AVR microcontrollers you’ve probably set the fuse bits incorrectly at least once. The ATmega fusebit doctor will automatically repair the fuse bits and get you back in business until your next mishap. The ATmega8 that powers the device has the chip signatures for the ATmega family stored inside [...]

[Csaba Bleuer] has built this really nice POV LED sphere.  Looking at the hand drawn schematic, it appears that he’s using an Atmega8 as the core. The resolution is pretty decent, and even shows fairly well on camera despite the refresh issues. Although much cleaner, it looks like a similar implementation to this one that [...]

This tiny biped shows a lot of coordination in its movements. As you can see, eight servo motors account for the locomotion with an ATmega8 as the brains of the operation. Posts for the first and second generation of this little guy feature several videos. We gather that a spreadsheet is being used to tweak [...]

[Viktor] wanted a system to keep his pipes from freezing.  The common method of using heat tape works pretty well, but can be wasteful. Many people just turn it on for the entire winter. [Viktor] wanted to automate the heat tape’s power so that it only activated during times that the pipes could actually freeze. [...]
