The Arduino Dev Board [Sticky]

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.)

Domino.io Module Tips and Tricks

Some basic instructions/ramblings to get started (as the documentation for the Domino module isn't currently complete)

To connect your Domino to a WiFi network using a GUI:

Raspberry Pi Header Tap

Here is a tap I created for the Raspberry Pi to allow access to the header pins even though it may be blocked by a "Pi Plate" / Shield that is using the header without pass-through pinheaders.

Driving a WS2811 RGB LED Strip with an Arduino

I recently purchased a WS2811 RGB LED strip for PC case modding purposes. I will be making an ATMega-based controller for it, so I decided to use an Arduino for testing and prototyping.

I found two libraries capable of driving this strip:

DFRobot LCD Keypad Shield and the LiquidCrystal Library

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:

Kenwood KDC-MP528 Internals

The Kenwood KDC-MP528 has the following goodies inside:

Acer Aspire 3000 Battery Internals

Acer Aspire 3000 Battery Internals

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.

D-Link DWL-120 Hacking/Probing

D-Link DWL-120 Hacking/Probing

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:

Flambeau Brake Control Demo Kit

Flambeau Brake Control Demo Kit

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.
