.NET controlled RC car with wireless camera

The project starts with a commercial remote controlled car that has to be modified so that it can be interfaced with the Phidget controller. The easiest way to accomplish this is to modify the hand-held controlling unit to receive input from the Phidget controller instead of a human driver.

The end result is a .NET-controlled RC car with wireless camera for stealthy operations.

ASUS Eee Pc Car Charger

ASUS Eee Pc Car Charger

You’ve probably seen the article about the Asus Eee PC and what can be integrated inside it’s case. But after you’ve done some modding and added different devices your battery probably doesn’t last as it was intended to last, so if you need to charge it in the car you either buy a commercial adapter or you make it.

This projects shows details on how to build an Eee Pc car charger. There are actually a small number of parts so the whole cost should be small.

Gas Guzzler Meter

Gas Guzzler Meter

The Gas Guzzler Meter is an attempt at putting an immediate dollar value on your current driving techniques: a digital meter that displays exactly what you’re spending as you motor along. Stomp on the pedal and see the bucks zoom out your tailpipe faster than a NASCAR driver competing for the Nextel Cup. This device will help you impress your friends, drive responsibly, and keep those dollars in your pocket.

PIC Based - Data Acquisition System

Why pay hundreds for a commercial Data Acquisition System when you can build the PIC DAS for less than $50.00? The PIC DAS is built around a Microchip PIC16C63A microcontroller and contains an 8 bit bidirectional Digital I/O port, 12 bit, 8 channel A/D converter and a 12 bit, 4 channel output D/A converter. It is perfect for quickly controlling any project on your workbench! Use the Digital I/O to sense switch closures with the help from the built-in weak pullups, control OPAMP’s, power supplies and the like with the built-in D/A converters.

Measure temperature or sense voltage or current with the built-in A/D converter. The real usefulness of this system is that it has a known simple to use interface that uses real ASCII commands over an RS232 link. This method of control saves programming time that would otherwise be wasted controlling the test setup, instead of actually doing the test.

SIM card reader/writer

SIM card reader/writer

Adafruit Industries just announced their next kit: a SIM card reader. Using the kit, you can read or write any SIM card. You could use this for fun things like recovering deleted contacts and SMS messages. The kit looks like a very straight forward design (based on Dejan’s work); the only chip is a hex inverter and the board is powered by a regulated 9V battery.

With all through-hole components, it should be easy to assemble. You can talk to it using the board mounted serial port or connect to the extra pin header using an FTDI USB cable just like the Boarduino. The FTDI option is bus powered, so you won’t need the battery. ladyada has collected some resources in case you want to learn more about smart cards.
