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 millijoules over the course of an hour. This was enough to turn their electric motor one quarter of a turn.

Wether you find this kind of biological hacking ethical or not, you’ll probably agree that the following quote is, at least a tiny bit, creepy.

The researchers tried different ways to connect three clams at a time as a collective living battery. A serial circuit boosted the battery’s voltage (electric potential), whereas a parallel circuit increased the current (rate of charge flow) — but the overall electricity available often changed depending on each clam’s health.

This LED table really ties the room together

Along with quadrotors, and portable game consoles, one of the hacks we never get tired of seeing is an LED matrix table. [Christian Enchelmaier] wrote in to share his take on the ever popular pixelated furniture, which we think came out pretty well (Translation).

Instead of going for a full-sized coffee table, [Christian] decided to keep things on the smaller scale his first time out, opting for an ottoman/end table nstead. He constructed a 16×16 matrix using RGB LEDs, encapsulating each one in its own “pixel”, as is common with these builds. [Christian] uses an Atmega 128 to run the show, displaying the current time and date, temperature, music visualizations, games, images, along with short videos. He also outfitted the table with an IR receiver so that he can control the table’s display from afar.

As of right now, [Christian] doesn’t have any video of the table in action, but there’s plenty in the way of pictures scattered throughout his build log to keep you busy in the meantime.
