The sponsor this week is Tokyo Flash, that’s right the company that makes the crazy watches that we featured here some time ago. Believe it or not the watches have gotten crazier than the last time I saw them. How cool would it be if no one else could read the time on you watch unless you taught them how to do it. No emails this time, we are going to do another Guess what this isn’t contest. We had lots of fun on the last one! Simply reply in the comments what this device isn’t and let us know the watch you would pick from Tokyo Flash.
Have a look at my first comment for an example entry. ———————————–———- Added July 29, 2009 The winner is comment 59. "Although it has been cunningly camouflaged with its surroundings. It is most definitely DARPA’s untested and highly dangerous new large scale mortar like 3D printer version 1.2. It uses a Gama radiation range finding system operating at close to 1 ZHz (zettahertz) giving it accuracy to 1/10,000,000,000,000 of a millimeter; this accuracy is vital as it needs to calculate the exact trajectory to fire the construction medium (sand stone) many hundreds of feet into the air and reach its precise destination in order to construct much needed temporary housing for the many beached aquatic mammals that appear ever more frequently these days." The winner is Alban ————————————–———- Below is a picture of the cool Kisai Denshoku watch, the Tenmetsu is also very cool!

Here is a great example of a DIY amp project. The TDA2050 Hi-Fi Chip Amplifier looks like a good chip to use for this purpose. There is full schematics and details provided so that you can build your own. Thanks Gio. "The amplifier is built around a single integrated circuit (IC), the TDA2050V which is produced by STMicroelectronics. From the data sheet, the TDA2050V is intended for use as a Class-AB hi-fi audio amplifier. The chip will operate within a supply voltage range of +/-4.5V to +/-25V. At about 25W of power output the efficiency is about 65%. One thing to note is that the gain of the circuit needs to be at least 24dB to maintain stability."

Pasqualy sent in this cool video of his modified RC plane that has been outfitted with rocket launchers and a camera. This is one way to get some unwanted neighbors to move in a hurry. "I did some air to ground rocket launching with remote video from the airplane. I also let the kids on the ground do their best to shoot me down using air bust fireworks. Made a great 4th of July.

It looks like the Engineers over at Transmin are having some fun with their robots and a Wiimote! It looks like so much to have that much power being controlled by a single Wiimote. I think this officially tops the Wiimote Sword Robot. |

Here is a cool way to increase the functionality of your EeePC. Have a look at this hack that adds E-mail Twitter and Pidgin Notification using a RGB LED. Via: HG Forum "This is an interesting little modification that i have completed on my EeePC901. Based on an Atmel aTiny45 processor it’s function is relatively simple, but as it is built from scratch, the build took some interesting twists and turns. My Led notifier uses a relatively small parts list:

Some computer companies like to keep their customers buying replacement parts direct from them and not from the local computer shop. That is the case with lots of products from the Compaq line. In this case the Compaq had a proprietary power supply but with a bit of hacking a normal one was able to be used. If you are ever in the situation where you have a Compaq EVO d500 SFF computer with a blown power supply you can now refer to this hack and fix it on the cheap. "The compaq mobo takes 3.3v and 5v standby voltages, but standard ATX psus offer only 5v. With the 3.3v missing the mobo won’t be able to turn the PSU on. There’s the option of hardwiring the PSON (perhaps to a switch, which would essentially be like an old AT psu functionality-wise, with the added trouble of having to switch the mobo on/off separately) , but that’s highly inconvenient and pretty lame

If you are looking for a compact, rugged, and cheap sensor filled package there is nothing better than a Wiimote. This Wiimote was Hacked to Analize Tennis Serves. It’s great that there is an abundance of creative people working to make interfacing to devices like the Wiimote a bit simpler than it could be if everyone was starting from scratch. Via: Hack a Wii "So if you are a real nerd or a high school physics teacher and you want to try this you will need:
