Harnessing the electrical power of clams

Yes, that is a clam. Yes researchers are using them as batteries. Yes, that quip about the matrix  and clam-Neo that is bubbling up into your temporal lobe is appropriate. While keeping a clam as “happy as a clam” might not necessitate a virtual world, they don’t really produce much electricity either. Researchers were able to siphon almost 29 … Read the rest

2012 Robogames this weekend in San Mateo California

Fifty dollars to make your car audio Bluetooth compatible

We’re rather impressed with the work [Aaron] did to add Bluetooth connectivity to his 2008 Honda. He used an aftermarket kit, but rolled in his own revisions to make it look and feel like an original feature.

After being disappointed by an expensive docking system he grabbed a Jensen BT360 kit for about $35. It comes with an external … Read the rest

Chess board step sequencer

[tinkartank] wrote in to tell us about the chess board step sequencer he built. It’s a great piece of work that combines the wonderful classical erudition a set of chess pieces confers with modern technological musical equipment such as a monome.

The build began by routing small holes underneath each square and fitting very small and fragile reed switches. Sixty … Read the rest
