Makieks spent about 30 hours and $65 building this Pearwood Computer Case. You can see a video of the original CAD design here. The water cooling system sight glass under the wooden buttons really makes the system look fantastic.
We featured an interesting CNC Halftone Picture technique that was done by Metalfusion. I have seen lots of people making halftone images using Photoshop since it has this capability built right in. If you don’t have Photoshop Metafusion has made a program which lets you import a picture and export a halftone DXF file. I wanted to give it a try but instead of using the CNC machine I wanted
This Double Sided Microcontroller Controlled PCB Exposure Box uses a PIC 16f268 to time the exposure LEDs on for the entered exposure duration. You can select if you are doing a single sided or double sided board, then you set the exposure time you need. After this you just sit back and relax while your board is getting perfectly exposed. We have seen some exposure boxes before including this UV
Kerry Wong shows us a project that allows for accurate Milliohm Measurement. For day to day applications your trusty hand held multimeter will probably do just fine, but when you need to make a very accurate low resistance reading this circuit is sure to help you out. “I used the reference design for the unity-gain difference amplifier AD8276 and a precision Op-Amp AD8603 from Analog Devices to form the precision
A walking robot like MABEL might not look that interesting to many people since humans do it all the time with no effort but when you think of the complexity behind what is being done in the video above you have to admire the machine! Thanks for the tip Fahd Via: Engadget “MABEL runs free for over 110 steps! In our opinion, this is the most realistic, human-like running achieved
This project by Robotics / Electronics / Physical Computing is an Airsoft RC Tank that Tracks the Enemy and Fires at them. Using IR LEDs on a target and a LEGO NXT brain the robotic tank drives around looking for the target. The tank doesn’t hit anything because it has an ultrasonic sensor in the front to sense the distance from objects. A Wiimote camera is used to look for
This would be a good time to hack your Apple TV to use the Couch Surfer Browser since you will then be able to make your Apple TV play HTML 5 Games! Please note that you will need to jailbreak your Apple TV first. Via: Slashgear and TUAW “A hacker installed the Couch Surfer browser on a jailbroken Apple TV and was able to demonstrate an HTML5-based game, Casino BlackJack.
