$4500 Book About A Car You Can’t Afford

October 9, 2009 by 24 Comments

4500-aluminum-car-book.jpg

The folks over at Kirkham Motorsports have turned out two things of beauty. The first is a sky’s-the-limit milled aluminum car. The second is a book about the making of the car that runs $4500 per copy. Why so much for a book? The binding is milled out of a 35 pound aluminum billet.

The project spans a 2 1/2 year build cycle and showcases the gamut of craftsmanship. The extremely detailed build log is available at their website in PDF form. Of particular interest to us is Chapter 10: Milling. The sheer volume of machined parts for this roadster is mind-boggling. There’s also plenty of CNC pipe bending involved with the body work in Chapter 18.

Finish up your work this morning and spend the rest of the day with this fantasy creation. If you’ve got too much to do, why not shell out for the hard-copy version and devote your weekend to metal-working romance?

ED, The Electric DeLorean

Who wouldn’t want a DeLorean, honestly it has to be the one of the coolest cars around, what with its gull wing doors and stainless steel siding. Joking aside [Tom Neiland] and [Dave Delman] went even further, creating eD, the electric DeLorean. It contains around 910 pounds of deep cycle lead batteries, custom transmission adapter plate, and a WarP 9 DC motor controlled by a water cooled 2000 amp Z2K-HV, all together to produce 200 horsepower reaching over 85 miles per hour.

The project cost ended up around $18,000 and they plan to add even more including a digital dash and Lithium batteries to extend the cars travel distance from the currently limited 30-40 miles on a single charge. Unfortunately the two couldn’t get their flux capacitor working, but we feel Dr. Brown would still be proud. Check out a video after the break and the writeup at Jameco.

Controlling An R/C Car With A Pic16F84

[GuySoft] sent in this project. He doesn’t normally mess with electronics, but decided to give it a try. He chose a fairly complicated project to be his first, but seems extremely comfortable with it. This project was to control his R/C car with a pic16f84. That chip was chosen simply because it was the only one available at local stores. Though we’ve seen much more complicated projects in the past, he does a great job of showing exactly what has been done. He shares his thoughts and source code with us as well. He has express a little frustration about the closed source compiler he was using, so if anyone has any suggestions for him, he would probably appreciate it.  The funny part is that he mentions that people would just tell him to “get an AVR”. We think the readers here will probably be happy with how he pulled it off.

Center Brake Light LED Retrofit

[Matt] wanted to increase the intensity of the center brake light on his car. The factory installed light uses a 20w incandescent bulb and although aftermarket LED replacements are available, he decided to take the retrofit on himself. Using the Fresnel lens from the light assembly as protoboard, he mounted a row of 10mm LEDs along with their current limiting resistors. He then broke the glass from the original bulb, removed the filament, and soldered directly to the two electrodes. This way the bulb socket can still be used to connect to the car’s electrical system.

Cheap Cup Holder Laptop Tray

[Michael Davis] sent in his homemade laptop tray. He does a lot of traveling in his Toyota Tacoma and was looking for a good way to mount his laptop inside. Unfortunately, [Michael] soon discovered that commercial laptop trays can be very expensive and difficult to install. He saw an opportunity in the empty cup holder in his car. Fifteen dollars worth of PVC pipe fittings and a piece of plywood later he had a laptop tray.

Custom Car Door Keypad

[Michael] has a keypad in his previous car’s door and he missed it enough to hack one into his Dodge Caliber. He bought a Ford keypad and mounted it inside his door with some custom electronics. He started with an Arduino nano to receive and authenticate button presses. This then splices into wires in the door that control the door lock. The program has a 5-digit code to unlock the door, but simply pressing 1 twice will lock the doors. He also implemented a lockout feature to prevent people from brute-forcing the combination. Although it isn’t wireless, it’s significantly simpler.

[thanks Michael]

OBD-II Automotive Data Logging

[Avi Aisenberg] sent us his final project for ece 4760.  His team built and OBD-II data interface. Even though OBD-II is an industry standard, each manufacturer has implemented it differently. This is where this project shines. They have built it to be capable of talking to any of them. Not only that, but it has a nice backlit LCD screen for diagnosing issues without having to go back to your computer and downloading the data. If you really don’t need all the bells and whistles, you can make one for roughly $15. They even have an OBD-II app for the iPhone.
