John’s been working on some updates to his Super Capactitor.
His current version is a sandwich of carbon fibre cloth around a [red] J-cloth soaked in water.
When you charge it up – acts as capacitor, and the fan goes round for 40 secs
His crappy robots plan is for it to sit in the corner and spin round knocking things over. For 40 seconds, making it ideally crappy.
Last Christmas party we had a few crappy robots fight it out. Here’s one made by John Willis.
John’s upping the ante by making a crappy robot powered with a home made super capacitor. Right now, it’ll light an LED for a few seconds.
Its approximately 10 sq in carbon reinforcement cloth in tap water.
The next steps are:
- measure the capacitance
- then test effect of temperature, ph, etc on output.
Watch this space for the crappy robot!
