Arduino is an open-source physical computing platform based on a simple i/o board, and a development environment for writing Arduino software.
Arduino can be used to develop interactive objects, taking inputs from a variety of switches or sensors, and controlling a variety of lights, motors, and other outputs. Arduino projects can be stand-alone, or they can be communicate with software running on your computer (e.g. Flash, Processing, MaxMSP.)

The DFRobot LCD Keypad Shield is found at DFRobot.com and various other retailers (Robotshop, etc)
To use this shield with the LiquidCrystal library, use this define:
Conversing with your Laser Printer:(See disclaimer below)
To extract information from your printer in PJL telnet to its IP address, port 9100 (or by serial, see below), and send it these commands:
Then copy and paste the following commands:
The Kenwood KDC-MP528 has the following goodies inside:
This is a 4-cell battery; before opening it up, I was under the impression that it was a 3-cell.
The charge controller circuit board has "LIP8198" and "1-867-277-11" markings in the silkscreen, along with a strip of Kapton tape over the top of the PCB.
I found 3 or 4 of these at a garage sale a few years ago for a few bucks, and I am (surprisingly) just cracking them open now.
On the front, it is marked as D-Link DWL-120 11Mbps Wireless USB Adapter, on the back is FCC ID# MXF-WL280, H/W: B2, F/W: 2.25
On the bottom of the PCB, we have the following chips:
This is a nice item that I found today at Princess Auto... A grey box hiding on the bottom of a grey shelf. The phrase "Demo Kit" caught my eye, and I had to take a peek inside. I was blown away by the beautiful innards, and I just had to have it.
I just got my shipment of stuff from BGMicro, including a ton of pinheaders!
1x Velleman 4x4 keypad
1x GI AY-3-8910 Sound Chip (and matching IC socket)
2x LEDs with wire and
1x 2.5" stero cable end (Digital Rebel XT Trigger?)
1x Graphical KS0108 Display
and Lots of 1x40 and 2x17 Pinheaders :)
This is my new Freeduino, which I purchased as a kit from the fine folks at the AlphaOne Hackerspace table at QuahogCon 2010.
