Finished Final Year Project
30th May, 2009
Presented in the last half hour of the first day… Here are a couple of photos I took while waiting after setting up in the middle room of Babbage floor 2.

Project Update
20th May, 2009
A typical picture update of the project from both aspects, the 3D and the physical interface.
Digital Atmosphere
Terrain Spikes
Testing the spike generator for visual feedback on the terrain:
Pulse Rate Sensor
Sensor in the Handle
Electronics
12th May, 2009
Although I’m still waiting to find out if the PCB I requested a week ago is ready I have been able to get on with trying to produce the remaining electronics.
I’ve found out that the Analogue-to-Digital-Converter of my USB board is pretty sensitive and simply connecting my circuits resulted in extreme noise rather than a smooth stable reading. So in order to solve this I’ve placed some beefier 1uF (rather than the 0.1uF on my GSR circuit) capacitors between the output and the ground which seems to stabilise it perfectly.
Powerful LEDs
Hopefully they will illuminate the centre of my handle, which now has acrylic beads glued into the holes in order to catch the light. I took this photo with my light on, not in the dark…
Thermistor Circuit
Note the purple capacitor across the thermistor. Without it the circuit gives out a perfectly stable current, but the ADC doesn’t seem to think so.
A Few More Production Shots
6th May, 2009
Just a couple more photos I’ve taken along the path of producing my biofeedback interface handle.
Simple biofeedback measurement and amplification:
After I had started making finger grooves:
Turned Wood
4th May, 2009
I decided to take a quick shot as a preview of the turned banksia nut wood before further processing. The material of the first one (bottom) was too soft to produce my modified bullet shape design, so I reverted to the simpler shape for the second nut.
The two banksia nuts turned into the handle shape.
The next stage will be to hollow out the centre of the handle to allow light and wires through.

Two pieces highly relevant to my own project’s field are Excretia and The Living Book of Senses.
The biomorphic font changes according to biofeedback input from the user.
