Capacitive sense buttons and pads are awesome, but many of the available systems are either propitiatory or require a dedicated IC. Toumas decided to code his own based on a closed source Atmel example where a single ADC pin is … Read more
First, an AVR that boots Linux. Now a Cortex M0 emulator for the ATtiny: I like writing emulators. Since my last one (ARM emulator that booted linux), I was wondering how much faster one could emulate an ARM cpu on … Read more
Martin tipped us off to an AVR/Arduino serial and mmc/SD card bootlaoder. It was designed to fit the same 2kb memory area that the usual Arduino booloader fits into, but can load firmware from an SD card too. Very useful … Read more
A common assumption is that you need a 32bit processor and lots of RAM to even consider running Linux, but Dimitry pulled it off with just an 8bit AVR. It is common to see newbies asking in microcontroller forums if … Read more
The 2012 Atmel Robotics Contest (ARC) is currently underway. The contest is open to university students 18 years or older in North America, South America and Europe, and the goal is to develop a battery-powered 3D version of the Atmel … Read more
Flylogic is known for their skills in reverse engineering chips. They were familiar with Atmel smartcards AT90SC3232 and AT90SC3232C and assumed that the AT90SC3232CS was similar but with an extra IO pad. They discovered the AT90SC3232CS is a completely new … Read more
Dustin connected his PlayStation 2 to a PC wirelessly using two RFM12 modules to make the link. On both sides AVRs with Arduino bootloaders drive the wireless modules. All the source code for this project is available.
Here’s a small breakout board for the ATmega32U4. A power supply, decoupling caps, button, USB jack, and an AVR programing header are populated on the board. As an added feature an open source bootloader that works with AVRDUDE is pre-programed. … Read more
Christopher Woodall from HappyRobotLabs wrote in about his recent project, Nomis, a Simon clone made using an ATTiny85. It uses up 4 pins, 3 for LEDs and 1 for buttons (ADC input). The write up can be found here. Everything … Read more
Alan Garfield at fromorbit writes: Hey guys, I built up that AVR Transistor Tester that’s been bouncing around on your site for a few weeks. Thought you might like to see it. I’ve done this short video showing it in … Read more
Mick built the ATmega fusebit doctor. It is a fuse recovery board for the ATmega family of microcontrollers. An ATmega8 uC uses the parallel programing method to reset the fuses for supported uCs. It is very easy to use. Just … Read more
A simple example of a Christmas light project using store bought LED lights and components you probably have lying around the shop. Mark VandeWettering found a set of battery powered LED Christmas lights and decided to combine this this an … Read more
Yoshi built a USBTiny MkII SLIM clone that fits into a Frisk candy case. It’s a USB AVR programmer that supports ATmega, ATtiny, and ATxmega families of microcontrollers. His project is open source and all the design files are available … Read more
If you’re at that stage as a beginner where you wonder what’s going on behind the scenes on an Arduino board you should check out jumperone’s tutorial on using microcontrollers. There you’ll learn what’s needed to take a bare microcontroller … Read more
pppd created a removable RC transmitter module based on ATtiny25 with the Logic Sniffer. Annoyed by an uncomfortable RC transmitter design and its stick mode, pppd decided to build a removable RC transmitter. It works by converting the standard RC PPM into the IR signal … Read more
Ejberg.dk has developed this project for a simple ATtiny2313 based servo tester. This device lets you test servos by varying the pulse width between limits of 0.8000 ms and 2.2000 ms selectable through the use of four buttons. While the … Read more
Atmel and Arduino have announced a cooperative effort to produce three new AVR and ARM-based dev platforms debuting at the Atmel-sponsored Arduino Pavilion at Maker Faire located in Queens, New York, September 17 and 18, 2011. According to Atmel’s press … Read more
Null Space Labs was tired of fighting the Dragon Atmel AVR debugger, so they make made their own programmer called the Kraken: The dragon is a terrible piece of hardware when it doesn’t work right, which is often. It has … Read more
The UK based crew from Batsocks develops and sells open source kits including breadboard related projects. We found a project they call the Tellymate which looks like a simple and easy way to provide plug-in video text output to any … Read more
SimulAVR is an open source simulator for AVR 8-bit Attiny and ATmega microcontrollers. SimulAVR can be used either standalone or as a remote target for avr-gdb. When used in gdbserver mode, the simulator is used as a back-end so that … Read more
