 Antonin Martin-Schouler had created a nice POV Globe. IR is used for position detection, a slip ring gets power over to the globe, it is packing some serious processing power with the ARM processor running the show. “For building the device using this tutorial, you’ll need the following material: The Zybo board from Digilent The Neopixel LED strip from Adafruit A 12 wires slip ring like this one
Language Warning on this video by AvE. If some swear words turn you off this video isn’t for you. This is the type of project that could come in handy when you find yourself stuck in the bush with no stores in site. We are shown how to use the resistive properties of the pencil lead to act as a voltage divider and drop the voltage to a save level for
Dave take a close look at Thin Film Resistor Networks. These are used in various precision electronic gear where extreme precision is needed. This one is from a Keithley DMM7510 7.5 Digit Multimeter and is stamped Fluke, I didn’t now that both companies were owned by Danaher. You may have seen a similar resistor trimming design on a large scale if you have ever purchased a high current monitor
The prize this week is a HMC5883L Triple Axis Compass Magnetometer Sensor so you can add some directionality to your next project. This contest will run for one week (April  12- 17, 2015). Ending time is based on central standard time. To enter, identify the item above and what it can be used for. Please do not give the answer in the comments.

These days projection displays are gaining in popularity and are very impressive. If you are working on a very large scale projection is the way to go but for smaller displays have a look at this complex system that uses 100 inch screens that are animated with ABB arms and have a video system that is in sync with the robotic movements to make some interesting visuals. “A RoboScreen
 If you are a heavy sleeper you might need an Alarm Clock that Opens Window Blinds. What better way to wake up than some rays of sun shine, this is assuming that you are trying to wake up in the morning when the sun is out. If you are a shift worker this might not work very well for you. “It is created using a Spark Core micro controller,
If you have some RC gear and a few bits of GPS electronics this project that iforce2d built might be worth a look.  Have a look at it in action at 2:40.  The user has a GPS module and the car has a GPS module, the module with the person sends its position to the car and the car goes to that location, issue with GPS is that it isn’t very
