Teenager invents vehicular antitheft system


We are very inspired by the story of [Morris Mbetsa], an 18-year-old Kenyan who’s invented the “Block & Track”, an antitheft and tracking system for vehicles that’s phone-based. [Mbetsa] has no formal training, but he’s been a lifelong inventor and tinkerer. [Mbetsa] combined voice, DTMF, and SMS text messaging technologies with cellphone based services to allow the owner to control the vehicle’s electrical system remotely. The owner, using his cellphone, can take control of the ignition, and disable it at any time. Other features include the ability to lock the car remotely, and the capability of dialing into the car and listening in on any conversations taking place within the vehicle. [Mbetsa] is currently looking for funding to take his invention to the next level; we’re eager to see what he’ll come up with next.

Picaxe tachometer


It might seem like we’re on a vehicle hacking kick this weekend, but [Rex] built an excellent custom digital tach for his race car. It uses the classic seven segment displays, a PICAXE microcontroller and works with most engines. He’s released full source and PC board designs to boot. This looks like a great little tachometer project for you microcontoller fiends out there.
