Pinewood derby car with camera…

 Weblog Racer1Awesome derby car mod – “I wanted to show you all the cool car my son Matthew and I made for his cub scouts pinewood derby. We wanted to do something entirely different and decided on mounting a very small camera to it along with an LED in the back to look like a jet engine. It was powered by a 9V battery which also served as the car’s weight. The car broadcast wirelessly to a receiver which we recorded on mini-DV. We won 7 prizes and finished 4th in the races.” [via] Link.

Making a Proximity Card

Making a Proximity Card

Prox-Reader-SimulatorHow Waterloo made his own proximity cards – “Lots of companies use proximity cards to control physical access. An employee holds their card within a few inches of the reader; the reader receives a unique id from the card and transmits it to some central computer that tells it whether or not to open the door. This is rather magical, considering that the tag is credit card-thin and contains no battery. The trick is the same as for RFID tags. The reader constantly transmits a rather strong carrier; the tag derives its power and clock from this carrier, kind of like a crystal radio.” Link.

Cleverly, MacGyver uses the purchases he had made with his debit card – everyday items at a convenience store – to free himself and escape to safety.” More info & Link to view ad.

Skateboards for schools!

Skateboards for schools!

H1Javier writes “Cool idea for enabling kids to actually make something usable in shop class: from the website: “The fact is, kids have always wanted to make skateboard decks in their woodshop classes but teachers and students never knew how to put the concave shapes and turned up nose and tail in the wood. Decks cut out of plywood and pine stock just don’t work! And where do you drill for correct wheel placement in order to get proper flex and balance? Well, Skateboardsforschools.com has taken care of all of that for you!” [via]. Link.
