Introduction We created gloves that allow users to type on any hard surface as if they were using a QWERTY keyboard. The gloves recognize the standard QWERTY keyboard layout by recognizing which finger is pressed, and how bent the finger is. It is limited to recognizing the three primary rows along the keyboard, from “q” […]
I love the Atmel AVR microcontrollers! Since building the Ghetto Development System described in this Instructable, I’ve had no end of fun experimenting with the AVR ATtiny2313 and the ATmega168 in particular. I even went so far as to write an Instructable on using switches as inputs, and extended the Ghetto Development System concept to CPLDs. During a

While I was writing some tips to solve problems about Spectrum’ keyboard, some guys asked me for the possibility of using a PC-keyboard coupled by adapter. One market solution was launched by ‘Sintech’, but isn’t available the scheme nor the program used by inner microcontroler. This lack of information pushed me to do an innovating

Introduction Sometimes you only need a simple and cheap RS232 terminal to get sufficient control over a PC or a RS232 device. There is no need, no space or even no power to place a monitor, a computer case and a keyboard. Maybe there exists also the problem, that the PC or the device is
