New version released ! V2.45 (Check version list for details) This construction is based on HappyJTAG Idea, to implement JTAG interface into target avr system and debug it remotly via USB, without specific JTAGICE hardware. All job is done by PC softraware. HappyJTAG version is easy , but not powerfull enough.There is barriere with performance, if […]

Why Stk500 and USB? Until the beginning of this year a simple parallel port programmer was the only good programmer as it could be used for any device. All device dependent information is stored in the programmer software on your computer. The problem is however that the parallel port is slowly disappearing. Apple does not

Introduction. Nowadays, USB is the most popular connection between PC and peripherals such as AVR programmers, printers, scanners etc. For that reason I had to modify my old serial AVR In-System-Programmer (ISP) to work with USB connection. You can say, “use a USB to Serial adaptor to connect your AVR ISP with your PC”. Yes, that could

Working with embedded electronics, you will eventually ends up with some sensor between your hands, here I’ll show how to make a graph out of it! This project involves a light sensor, a tiny 8-pin AVR USB key with the V-USB stack, a GNU/Linux system and rrdtool. Sensors If your are working with some digital sensor

Introduction: A good while back, I made the 1-key-keyboard project. Ever since it has always been in the back of my mind that the ATTiny microcontroller, which I used in this project, had still 3 IO ports which were unused. Only recently I’ve found the time to expand my old project in the most obvious way

Easy Input is a head-controlled keyboard and mouse input device for disabled users. The system uses accelerometers to detect the user’s head tilt in order to direct mouse movement on the monitor. The clicking of the mouse is activated by the user’s eye blinking through a reflective sensor. The keyboard function is implemented by allowing

DESCRIPTION This project is to make a clone of Arduino Leonardo in a simple way.That is why the distribution of the pin does not match the standard Arduino (have to make many jumpers on the motherboard or use both sides). However, most Arduino Leonardo characteristics are maintained. The circuit is protected by an automatic reset fuse

Introduction We created a handheld mouse device that measures its tilt and then wirelessly transmits the data to a base unit, which is connected to a PC through a USB cable and can be recognized by certain modern computers as an actual mouse. The purpose of this project was to explore the possibility of creating

Introduction For our Final Project in ECE 4760, we built a controller that interfaces with a computer running a PowerPoint display through USB. The device can control slide transitions based on hand motions or button presses as well as play MP3 files when it detects people near the display. We chose to do this project

This project is about to DIY an Arduino board wth an ATMEGA644P or 1284P to have more INPUTS/OUTPUTS than on the atmega328P. You can buy an arduino mega but it’s more expensive. The microcontrollers will be bootloaded with Sanguino and the project seems to be like another one called CALUNIUM. On this clone you will
