This DIY cell phone created at MIT manages to have something for just about every major contemporary subculture or hipster subset I can think of. Nerds and tinkerers? Check. Wooden case for the steampunk set? Check. Huge antenna for the retro, skinny-jeans-wearing set? Check. Big buttons for the fat-thumbed and Luddite crowd? Check. Rugged design […]

The AVR ATXmega chip is a newer offering in Atmel’s AVR line. The Xmega is billed as a hybrid 8/16-bit MCU, which means you can use your normal development environment to program Xmegas (as compared to AVR32 and Atmel’s ARM line). Because the Xmega uses a different programming interface, it does require a programmer that

If you have been playing with microcontrollers and electronics then you have likely seen LED dot matrix displays and other projects that use shift registers like 7-segment displays and more. This instructable goes over a quick intro to the 74HC595 8-Bit Serail to Parallel Shift Register with Latch and how to interface it to an

* you’ve got your arduino with atmega168 and you bought an atmega328 at you local electronics store. It doesn’t have an arduino bootloader * you want to make a project that doesn’t use arduino – just a regular AVR chip (like the USBTinyISP) – you have a clean attiny2313/attiny48 etc that you want to burn

Shift registers are a very important part of digital logic, they act as glue in between the parallel and serial worlds. They reduce wire counts, pin use and even help take load off of your cpu by being able to store their data. They come in different sizes, with different models for different uses, and

The Siemens DLO7135 Dot matrix LED is one amazing piece of optoelectronics. It’s billed as a 5×7 Dot Matrix Intelligent Display (r) with Memory/Decoder/Driver. Along with that memory, it’s got a 96-character ASCII display set with upper and lower case characters, a built-in character generator and multiplexer, four levels of light intensity, and it all

Hi techies!! This is one more of my circuits, interfacing ATmega32 with an LCD and a DAC. it also includes two general purpose push-buttons and In System Programming connector. The controller is operating with 14.7456 MHz frequency crystal, convenient for generating standard baud rates (for RS422 communication whic i used in my actual project, not
