[imsolidstate] built his own pressure sensitive mat. It utilizes two discs of copper clad board with a piece of foam in between for each of 64 sensors. As the foam gets compressed, the capacitance between the two pieces of copper changes, a measurement that is fairly easy to make with an analog to digital converter. The mat is being used to measure how well a horse saddle fits the animal. Data is read in through a serial port and then mapped using Excel. This prototype proves that the concept works but [imsolidstate] mentions that there’s room to improve the sensitivity and that there could be more noise filtering incorporated into the design.

After reading about cheap wireless for microcontrollers, [Leigh] left a comment about his Marauders map. Much like the Harry Potter version, whoever holds the ‘map’ is able to see the location of the ‘marauders’ within certain bounds. Unlike the magical version however, each person being tracked needs to hold a PICAXE 08M, GPS, and 433.92MHz transmitter: while the map needs a computer running his Python script and a receiver of the same frequency. It has the potential for locating people, but we feel it might be better off in a swarm robotics setup.

The term ‘warwalking’ isn’t used very often, but the Ekahau HeatMapper adds a new tool to the pod bound hacker’s arsenal. The tool maps out wireless access points as well as their signal strength within a facility. A test of the HeatMapper on a map made with AutoDesk Dragonfly accurately determined the location of a router within 3 feet and helped tune the angle it needed to be at for maximum range. Ekahau made a fantastically cheesy promotional video for their product, which is viewable after the jump. The program is free of charge, but unfortunately only runs on windows, so mac and *nix users are out of luck, though it might run under wine.

We were pretty excited by the prospect of location-aware software and its ability to pull map data into its functions, but what do you get when build software on top of a map-based service? Well, one possibility is 2D gaming on real maps.
