Main hardware projects

The JeeNode is a module with an on-board ATmega328 MPU and an RFM12B wireless transceiver for the 433/868/915 MHz ISP frequency bands. It’s compatible with the Arduino IDE.
The JeeNode USB adds an on-board USB interface and LiPo charger and uses SMT parts.
The JeeLink is a USB stick which can be used as wireless node. It has no connectors, but includes 4 Mbit of flash memory. See this side-by-side comparison for a quick overview.
The JeePlug is a tiny prototype board to connect sensors, lights, chips, whatever. "Plugs" also refers to a range of little boards which can be easily mixed, matched, and re-used.
ISP programmer - uses a JeeNode to upload code and set the fuses of another ATmega or ATtiny chip via In-System Programming. Based on the Flash Board with on-board EEPROM memory.
Reflow controller - reflow soldering with thermocouple, FS20 power switch, grill, and JeeNode.
Ether Card - this is a simple Ethernet card for use with a Carrier Board, or an Arduino, RBBB, etc.
The LED strip controller uses a JeeNode plus MOSFETs to control common 12V LED strips.

JeeHub - an older project which uses a JeeNode, but specialized as gateway for collecting data from other JeeNodes and connecting to a computer.
A CNC router and 3-D printer are being built at the Jee Labs, to learn about CNC and to try out some fun ideas with stencils, pcb’s, enclosures, front-panels, etc.
MuxShield - a shield for the Arduino which turns it into a 5-line serial multiplexer. Will re-flash up to 5 attached FTDI-connected boards, such as JeeNodes, RBBB’s, etc.

Ports library - supports simple I/O on the four “ports” of a JeeNode (though it’s not JeeNode-specific). It includes drives for many of the plugs, and numerous example sketches.
RF12 library - interrupt-based driver for RFM12(B) modules by HopeRF, connected via SPI.
RTClib library - utility code for time and date manipulation. Can be used with the RTC plug.
JeeMon - a switchboard-type networked application for physical computing devices. Lets you collect, store, process, and visualize incoming data from attached devices, as well control them.

Projects On Foam - a low-cost/low-tech approach to setting up projects with JeeNodes and JeePlugs, to easily try out things and then reuse everything in other projects again.
Low Power – this is a frequently recurring topic on the weblog. Posts related to reducing the power consumption for battery-operated use have been tagged for easy reference.
Sensors - this links to all the weblog posts about this topic.
JeeBot - a low-priority / fun project to create a battery-powered robot vehicle controlled by a JeeNode. The TwitLEDs robot was a more recent spin-off of this.

A 5-part series about Open Source Hardware (and software) – I like to think that it adds something new to an overstretched topic.
A 2-part hand-waving attempt to elaborate on what I’m doing and why I’m doing it.
