Introduction

Welcome to my projects web site and blog. I'm a hacker, not just a hacker of software, but also a hacker of hardware too. I majored in physics and have some training in electronics but I am mostly self taught. This doesn't stop me having ago at electronics design and frabrication. Below is a list of my projects and a little bit about each one. New projects will appear at the top. Enjoy ...

Beebthernet

This is an attempt to develop an ethernet interface for a BBC Microcomputer. The interface is based around the WIZ812MJ part which itself is based on the W5100 chip. The chip is an ethernet adapter micrcontroller which includes an embedded TCP/IP stack. The board is access via bit-banged SPI on the BBC's parallel port. The board also includes power regulation, address decoding,a socket for one of Microchip's SPI EEPROMs and expansion connections (the SPI bus together with power and to address lines).
