Most of the time, I build my own ideas. I can put most things together using wood, plastics, metal, paper, fabric etc as appropriate. When electronic control is needed, I usually program a PIC microcontroller to do the job for me. Some of my projects (for example speed demo-dating) involve only a computer.
Hands-on exhibit prototypes
I have many ideas for hands-on exhibits, some of which I have turned into working prototypes.

Science demonstrations
I have built a number of science demonstrations, some of which have won prizes.

Assorted creative and building projects
In this section I describe other projects that don't fit into the categories above. Walking on water, Scrapheap Challenge, speed dating, a K'nex clock, a skateboard ramp...even a pair of elephant's feet.
