Un-crapifying a Car Stereo

[Noah Farrington] has just accomplished a major milestone in his life, purchasing his first car! A glorious 2001 Ford Focus wagon. While it may be a fully loaded luxury vehicle, it is missing one thing poor [Noah] can’t live without. An aux-in port. He had a few options for rectifying the situation. Live with it as is, hack the strange Ford media protocol out of the back, or fool the CD player into playing his input. Naturally he chose the third option.
Un-crapifying a Car Stereo
His first challenge was removing the deck from the car. People told him he’d have to buy fancy stereo removal tools — he made do with tent pegs and coat hangers. Using the same method as described in a past aux-in hack, he identified the audio in leads on the CD player’s ribbon cable. By carefully soldering in his own aux-in plug, he’s almost ready for business! Unfortunately, the CD player also needs to think that it is on for it to properly output the audio. [Noah] chose the simple solution — record a silent CD to always leave in the deck. Stick around after the break to see it in action.

Homemade 105 MPG Car

Jory Squibb made his own 105 mile per gallon car – “Moonbeam is 79″ long, 52″ wide, and 56″ high. It is made from a 1987 Honda Elite 150 motorscooter in excellent condition and another 1984 Elite 125 parts bike. It weighs 386 pounds unloaded. It cost $2339 in materials and 1000 hours of labor. The front tires
have a 40″ spacing and a 56″ wheelbase. The tires are 3.50-10 and 4.00-10 on the rear. The car goes 53 MPH on the level, but I find that speed worrysome.”

Make an RC Airsoft Tank

RC toys are always fun, especially when you can add weapons… I was given this RC car for Christmas, and it came with a switch on the remote for lights you could turn on. I tore off the body and clipped the wires to the lights. It turns out they put out a nice 10v signal. I quickly grabbed my tiny breadboard and using its adhesive, glued it to the RC car ( there was a perfect plateau to fit it on).

Then I headed to dunhams and bought the cheapest electric airsoft gun (25$) and attacked it with my dremel…With a 6v DC relay I put it all together and oila, a sweet RC car with a fully automatic weapons turret!
