informal tests with Blackberry show much improved response (i’m actually a bit surprised; i would have expected the Blackberry to be engineered to eliminate as much background noise as possible). Sounds lasting over about 1/2 second from what i could tell though were attenuated quite a bit. tests with 250ms per 100 hz step actually [...]

Initial tests with LG8100 cell phone (my old skool phone), recording to WAVs on an Asterisk server. Purpose is to roughly determine usable frequencies via cellphone. Older references on POTS system indicate usable range is 300hz – 3khz; System uses XP100 card, echo cancellation enabled, no TX/RX gain, 5 seconds of pure (well, relatively pure [...]

So after doing a bit of digging around on BEAM robots, the swirlies visualization, etc. i started playing around more with the whole electronic neuron thing. since then i’ve been playing with a number of different configurations, pretty much all logic gates with RC circuit inputs. One of my favorite at this point is a [...]

This is a Processing sketch i put together to visualize operation of logic gates in neuron-like configurations (inspired by Nv nets & related). I was working on circuit designs using logic gates w/RC circuits at the input, and wanted to be able to do visualize how things would work for the prototype project due in [...]

This is an FBD of a hammer being held in the air (no motion) for class. Note: Since the hammer is held at an angle in the picture, the forces should be scaled by the cosine of the angle between the ground and the handle. Also as discussed in class with a solid piece like [...]
