I think I wrote about the bus pirate some time ago.
A logic analyzer is a device that lets you watch digital signals in your electronics project. You can watch them real-time or log the data for later perusal. Unlike an oscilloscope, its not good for measuring analog signals – but also unlike an oscilloscope, you can track 8 signals at time! So its a good complementary tool. This logic analyzer plugs into a computer and has easy to use, cross-platform software. This makes it small, portable and inexpensive. If you ever have to to debug SPI, i2c, serial, CAN, 1-wire, Manchester, biphase or other digital protocols, this tool is essential!
Well the stupid clips on my eeePC 1005HA that holds the ribbon cable in are weird, and I broke one and lost the other. FAIL! Anyway to un-fsck lappy I now need to acquire the clips, which so far I have been failing at. I did find the SATA/Audio/USB boards for sale w/ ribbon, just need to see if both clips are there or what.
Part Numbers it could be (I need to verify this on the board)

“Our goal is to release a new open source hardware project every month. Copies of our projects are available through Seeed Studio and our distributors. Projects usually cost $10-$40, including worldwide shipping.
Ian Lesnet first worked with Seeed Studio to make open hardware available while writing for Hack a Day. Ian started DangerousPrototypes.com in 2009 to sell future open source projects.”
Amplifier bridging is simply using 2 channels of an amplifier to drive a common load. For 2 channel amplifiers, one left signal and one right signal is used to drive a mono speaker load. Keep in mind that mono and bridging are not necessarily the same. Mono means that there’s only one output signal. There could be more than one speaker but each speaker will have the same output. Bridging means that you are using more than one source of power to drive a load (speaker). The sources of power are one each output from either channel of the amplifier. A long time ago, amplifiers had signal on the positive output speaker terminals only. To bridge one of those amplifiers, you’d have to use some means to invert the signal on one channel (remember the old ‘bridging modules’ for Orion amplifiers?). Today’s bridgeable amplifiers have an inverted channel as part of their design. For many amplifiers, the left positive and right negative are are the signal outputs. A few use the left negative and the right positive. Others still (mostly mono amplifiers that are to be used in bridged pairs) require that you choose 0° or 180° via a switch to invert the signal.
Ok this is awesome:
…and a aftermarket firmware to make it h0t:

Based on tom and roland from wingmanteam work.This is a tool that log the usb data exchange between hardware and device driver!
SixthSense is a wearable computing device that contains a camera and a projector and allows the wearer to interact with digital objects in a physical way.
I’ve seen this before and regarded it as just another really cool project from MIT. In the video Pranav makes a stunning announcement — that all the SixthSense stuff is going to be opensource!
