Arduino PS3 Arm control
June 2018
No more USB drivers led to a modification to this arm.
Now it is controlled by a PS3 controller through an Arduino Mega 2560.
Pololu PTZ Controller
February 2014
I needed a cheap controller for a Pan Tilt Zoom camera so I chose a Pololu Mini Maestro 24 Servo controller.
I programmed it to convert inputs to Pelco-D protocol and drive an LCD display.

An attempt at making my own 360 deg pressure sensor with QTC pills, it did work although needed a large threshold window.

September 2013
I wondered if a servo controller could be programmed to display on an LCD display to show program info....
Turns out it can.

Camber & Toe Rig
With all the work required on my Vectra, I needed to make a rig for setting up the camber and toe.
This one did the job nicely although a little flimsy.

Robot Hand V1.1
February 2012
An early attempt at machining robotic parts. This worked ok, although had too much wear and was a little heavy.
2 Storey Bird Table
May 2011
My first attempt at making a bird table.
I didn't own a milling machine at this time, just hand tools.

3D CAD First Attempt
April 2010
This was my first attempt at using Alibre Design, a 3D CAD package that has a good tutorial package.
Fly Wheel
April 2010
Can you guess what this is used for?
The title may give it away if you were fishing for clues!

Modded Honey Bee King
August 2008
I could just about fly this awesome machine, but the main reason for buying it was to see how it all worked.
I still have it, having crashed and re-built it several times.
One mod was to use the downwash to cool the speed controller.
Leaving Gift
September 2005
Before Microprocessors I used to design logic circuits to control outputs from inputs.
This is one of my circuits that controlled timed motor position and controlled its direction, activated by a switch.

PWM to Trailer Socket
September 2014
I bought a 12N trailer socket and some 7-core cable only to find the car uses Pulse Width Modulation to control the brake lights.
So I made a simple relay box to detect PWM and control separate relays.
