I’ve been making a few modifications to *.carlheaton.co.uk like re-introducing the core Carl Heaton index page with a list of projects and other on-going ideas. I will still post tutorials/dumps here where appropriate for code, server and electronics related things, but I’ll be posting no further ‘random links’ on this Slog because it’s too much [...]

http.sh
I’ve faffed with this one and poorly hacked some jquery and facebook connect examples along with trusty ol’ PHP on the front-end, on the back-end is a nice c scheduler engine which seems to be performing extremely well during testing. The index and FAQ explains what it’s all about.

It’s intended for the ‘education’ of people too lazy to use the wonderful search tool called Google. How many MB are there in a GB? duh, http://jfgit.com/how+many+MB+in+a+GB/ or http://jfgit.com/clean/how+many+MB+in+a+GB/ if you prefer.
Ardunio Visible Distance Detector
I’ve had the Arduino Mini Pro for about 2 months now, but as I forgot to order/have some sort of USB FTDI converter I’ve not been able to play with it. As part of another planned project I intend to use the SRF02 ultrasonic sensor to detect and alert upon someone getting too close to [...]

/* This code receives input from the SRF02 ultrasonic and maps the values to RGB outputs to a tri-colour LED. */
Arduino and HD44780 LCD
I’ve just been playing with a new HD44780 4×20 LCD from ebay on the Arduino. As I’m still ‘playing’ I’ve tried to document a kind of breadboard interface for the Arduino to LCD. It should help me to remember how things are setup so I can use it a modular fashion later.
