On the the East CAC Facebook page, some neighbors recently asked if the police department was using acoustic triangulation systems for tracking gunfire. I responded that systems like ShotSpotter were interesting but that the police department couldn’t afford the $300k cost.
Ah, the joys of open source! It turns out one enterprising hacker has built his own Arduino-based triangulation system using easy-to-obtain parts. This has me thinking that if a few neighbors here and there were willing to station these near their homes, the fixes that could be plotted would be extremely accurate. Even a small network of these would do wonders. In this way, neighbors could be helping to fight crime in their area without actually having to do anything. It sounds like a great solution!
MicLoc is an effort to develop a device capable of passively identifying a sound based event position on a given map, therefor pinpointing its location. The whole idea is to achieve this goal with everyday electronics and reduced development costs.With the event of small, affordable, powerful microprocessors and electronics in general, this technology now seems accessible to potential commercial applications and general public use.The main goals of this project are:
- Develop a low cost, compact device capable of identifying a source source location on a map with sub-meter precision.
- Develop, detail and open-source the hardware and plans used so anyone can build this device.
- Develop, detail and open-source the software needed to interface the device with a computer.
