This section of the site is going to discuss various electronic projects that I have worked on. It’s currently under construction, so check here often and see what cool stuff shows up….
I like to build network-connect devices that talk via ethernet. Typically such things can be connected to the Internet and accessed remotely.
An example is my Network Thermometer, which allows you to see the temperature in a room form anywhere on the Internet, and my Network Power Strip, which lets you turn AC devices on and off from over the Internet.
Building a device that connects to an Ethernet and has a TCP/IP stack would be very hard to do from the ground up, so I’ve used something from Rabbit Semiconductor called the RCM2200. The RCM2200 is an embedded CPU with flash, ethernet, ram, etc. It’s everything you need to build a network device. Just supply it with regulated 5VDC and it’s good to go.
