 If you are looking to jazz up your look this Halloween why not add some lighting effects to your face! Adafruit has a great tutorial on how to use their GEMMA microcontroller to make it happen. The tiny GEMMA is using a Attiny85 and is programmed using Arduino, it looks to be a great platform when you don’t need much power and only a few IO pins.
ISeeAll has been working on a Halloween Moving Skull Project which used an Arduino that is monitoring 5 photo cells so that it can watch shadows of people walking by so that it can look at them. move to predetermined positions based on which sensor is shaded. I think a room with even one entrance can be made very spooky with something similar, just have an IR beam on
 The headlights of some BMWs have some cool looking daytime running lights, they have acrylic light pipes that produce a ring of light. A cool looking upgrade is adding LED rings which are brighter and really make the lights look cool! Since the headlight units are sealed this mod isn’t that easy, but the results are worth it. “Conclusion: I highly recommend anyone else considering this just let
Julian Ilett demonstrates his Arduino Solar Charge Controller. He has mounted all of his Arduino modules to a piece of wood to keep everything nice and neat. “High efficiency values (96% – 97%) are achievable when the buck converter is stepping down from 18v to 12v. With a 72-cell panel and the converter stepping 35v down to 12v, the efficiency drops to around 88%.”
If you want to fly an RC plane but don’t think getting used to flying with a standard RC remote this glove control system might be a build that could help you fly. It has some interesting features that help to make flying the plane more intuitive such as simply tilting your hand from side to side to bank the plane instead of moving a joystick. “The Spatial Hand
If you like working with foam you can easily carve up a large block of foam with a carving knife but that isn’t very accurate and will make a huge mess. The cuts won’t be very smooth and it will take a long time to make something look good. The solution is a hot wire technique, a hot wire will cut through the foam like butter allowing the user
If you want to make your next robot be able to use hands like a human the Open Hand project would give you a head start in this direction. Building a cheap model of the complex human hand is no small task but if this campaign is successful I think we will be heading in the right direction. Via: Make “The Dextrus hand works much like a human hand.
