A weblog focused on interesting circuits, ideas, schematics and other information about microelectronics and microcontrollers.
Ftisp is a command-line utility that allows program AVR processors via an USB chip FT2232 or FT232R.
Ftisp uses the fast synchronous bit-bang features of this chips.
An older article, but a good idea... Logic probe on steroids.
The RBox is a game console that is simple enough to build on the prototype area of a LPCXpresso ARM dev kit. You need just a crystal, a few capacitors and resistors. It uses the smallest and cheapest 32 bit CPU to generate 3D graphics and sound.
Three circuits with AVRs, implementing a simple BASIC interpreter.
JS16 is a very minimal USBDM version based on MC9S08JS16, that supports HCS12, HCS08 and Coldfire V1 devices. It is easy to construct and may be initially programmed over the USB.

How to work with FORTH on your Parallax Propeller board?
I bet you know a lot of artickes on "How to connect 1-Wire device to AVR". Here is the problem reversed: How to simulate an 1-Wire device in AVR?
Yes, we all know many emulators of old processors "on the chip", but as far as I remember this is the first attempt to emulate a CP/M machine (including Z80) I ever seen.
There are a lot of devices with LPT (Centronics) interface, but newer computers haven't the LPT interface. Here is a solution...
