Autoblog dug up this classic mechanical engineering project from 2006. A team of five University of Toledo students constructed a system to help parallel park a car. First, you drive nose first into the space. Hydraulic rams then lower the drive wheel out of the trunk, raising the rear of the car. The single wheel is also hydraulically driven and moves the car into the space. They have a blog documenting the six week build. Have a look at the demonstration video below.
Cheap radio controlled toys can provide countless hours of amusement, especially when friends have one too. You can’t always plan ahead enough for everyone to have a different frequency and sometimes, it just isn’t an option anyway. There is a solution, and it isn’t very difficult. [frickelkram] takes us through the process of changing the frequency that the toy runs on. He starts with the simplest way, which involves replacing one piece in the controller and simply adjusting the receiver. He notes that this often fails as the receiver just isn’t built to be adjusted easily. He continues to show how to get it done even if the first method fails.
We were surprised last month when we saw augmented reality being done completely in flash. It hasn’t taken too long to go mainstream though. MINI has incorporated it into a recent German language magazine ad campaign. The fiduciary marks actually work quite well with MINI’s established ad format. Visit the ad’s URL and hold the magazine up to the webcam and a 3D model of the MINI Cabrio will appear. They have a PDF of the ad that you can print and use if you don’t have the original. Unfortunately, it doesn’t seem to have cross-platform support.

[Ron Alsing] wanted to try out some genetic programming, so he created a simple test problem: Could you render the Mona Lisa using just 50 semitransparent polygons? The program starts with a random DNA sequence. It then mutates and compares itself to the original image. If the mutation is closer, it becomes the new sequence. The final image he shows looks pretty good after 904,314 iterations.
[prunesquallor] pointed out a genetic algorithm project of his own. It’s a flash program to evolve a car. The car tries to get as far as possible on a set terrain without the passenger circles hitting the ground. The wheel size and positions can change along with the spring length, constant, and damping. A graph tracks the best performance along with the mean. He’s planning on building a version that lets you change the parameters.

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.

Autoblog recently posted about the LusoMotors LM23, a track car powered by a Honda CBR1000 that weighs less than 900 pounds. We knew there have been quite a few other home built cars that have foregone traditional engines for motorcycle power plants, so we asked Google for a few project suggestions. It turned up this excellent round up of motorcycle powered cars by The Kneeslider. The usual Caterham suspects show up, but there are many other unique vehicles: from Mini and Fiat conversions to the unique sidemounted engine in the DP1 pictured above. Definitely check out this excellent collection.
Progressive Insurance announced that it will be rolling out its MyRate plan nationally. You participate by plugging a monitoring device into the ODB-II port on your vehicle. Once every six months you upload the collected data from every trip you’ve made. You’ll receive at least a 5% discount and maybe more based on your driving habits. In some states though, you could actually have your rates raised. Progressive will show you the direct impact your driving behavior has on your rate.
