Running out of space in your big Arduino project? Good news! Finally you can buy the latest improvement to the ATmega8 line of chips: the ATmega328!

Attach any I2C client chip (thermo sensors, AD converter, displays, relais driver, ...) to your PC via USB ... quick, easy and cheap! Drivers for Linux, Windows and MacOS available.

The goal of LCD2USB is to connect HD44780 based text LCD displays to various PCs via USB. LCD2USB was meant to be cheap and to be made of easily available parts. It is therefore based on the Atmel AVR Mega8 CPU and does not require any difficult to obtain parts like separate USB controllers and the like. The total cost (without display and pcb) are about 5 to 10 Euros. LCD2USB currently comes with a simple demo application that works under Linux, MacOS X and Windows.

Great idea - USB scope with only ATtiny 45 for less than 10USD with a homemade pcb. USB is software-based, so no extra USB chip is needed.

Just for fun: Popular Electronics, January 1975 with the most powerfull minicomputer project ever presented - Altair 8800! Enjoy!
