The Copenhagen Wheel recently demonstrated at the Copenhagen Conference on Climate Change is a clever device that can store energy every time you apply the breaks and then reapply it in the form of motor assist as you ascend a hill on your bicycle.
In my previous SPARK post, I created a program that sends serial port commands via an XBee transceiver to control lights plugged into a modified power strip. It was nice to see this level of functionality, but since this is my last SPARK post, I wanted to add a little pizzazz to the project. The […]
It’s been out less than a week and the Barnes & Noble Nook eBook reader has already been rooted. Interestingly enough, it would seem that the eBook reader’s default custom Android system is installed on a MicroSD card.
In my previous post, I finally started to make some progress with my Windows Embedded CE project. I was able to get a simple test application running which could send and receive messages via a serial port on my iCop eBox 2300 computer. I first sent messages to a host computer using an RS232 crossover […]
In my previous post, I described how I was able to program an iCop eBox to transmit date using an XBee wireless link. The program was written in Visual C++ and executed serial port commands to send data to a host computer. I had previously set up the XBees to communicate at 115,200 baud, but […]
You don’t always need a micro-controller when using an XBee for data collection. This wireless temperature sensor uses an XBee, along with a simple breakout board, and power supply to transmit the data to an Arduino base station.
Blinking an LED and transmitting text to a serial terminal is not the most exciting thing in the world, but it’s very cool to breathe life into a balky computer, even at the most basic level. Also, I have worked with enough development tools to know that it can be a lot of work going […]
