HOW TO – Sandals from an old auto tire
Fun Instructable on making a pair of sandals from old tires Cthoyes writes – “Ok, to be fair, I originally saw this here and thought I would see how it goes. That website has good instructions but not many photos. So, I thought I would try it and take photos. But anyway, you need a pattern first. Trace your foot and then trace about 1/2 inch around that for the sole. You’re also going to need to mark the tabs. You can flip the same pattern over for the other shoe providing you are not horribly asymmetrical…” Link.
“A speed trap measures the timing of events or speed of projectiles “This is a very affordable and simple to build speed trap based on the PIC 16C84 microcontroller. The goal was to use as few parts as possible while adding as many useful features as possible.”

Ellen writes “Children have been clamoring for Floam, a micro-beaded modeling clay that has been heavily and attractively advertised. Unfortunately, people who have ordered Floam report long delays and deceptive business practices. Instead, make your own Floamâ„¢-like clay in whatever quantities and colors you like. We found several anonymous recipes online. My husband Keith Golden tried three different recipes, then refined the best one. The result is virtually identical to Floamâ„¢ (except for smelling better).” 
The RFID-Zapper is a gadget to deactivate (i.e. destroy) passive RFID-Tags permanently. The development-team presently consists of two people. Goals are a proof-of-concept and the construction of at least one functioning and appealing prototype, as well as a documentation of the project, so that everyone can build an own RFID-Zapper.
