Looking for something fun to do this Halloween? How about scaring the crap out of people everywhere. Alton Porter has a pretty good setup for this. It looks like adding a lightweight skull (either wire-frame or Styrofoam), some LED eyes, and some tattered cloth. Just make sure you don’t interfere with the blades, nobody wants you to crash your quad!
This would be amazingly cool with a swarm of small drones. Great idea.

With the advance of affordable 3D Printers, the home brew R/C vehicle community is booming with people making and designing their own parts. However, making your own RF controller is a different story.
Armed with a pair of Arduinos and nRF24L01 modules, Mujahed has a good start on one. On the transmitter side he’s reading a joystick module with an Arduino Uno and transmitting with one of the nRF24L01 modules. On the receiver side is another wireless module feeding an Arduino nano that is tied to a few servos. Everything on the car side is running off of a standard r/c car style 1800mAH battery.
More info and wiring diagrams on Mujahed’s site. Check out the video after the break.

Ranking up there in the category of possibly over engineered cat toys, is the TinyLaserTurret. This will probably keep you _and_ fluffy entertained for at least a few hours.
The brains of the operation is an ATTiny85 microcontroller. The unit is controlled by a Wii Nunchuck (using the WiiChuck adapter). Pan & tilt are made available via servos. Then there’s a 5v red laser module for that mysterious dot that fluffy can’t seem to ever catch. Because of current requirements the laser is driven with a transistor. Everything is mounted on a 3D Printed frame.

On the 20 some-odd remotes I have around the house, I know there are a bunch of buttons on some of them that don’t do anything for my model of whatever it controls. Badr noticed the same thing on his satellite receiver. So he decided to give those extra buttons something to control.
Armed with a little IR transmission know-how, a 16f84a, a transistor array and some relays he added support for controlling his some lights and a fan.
He’s got a schematic and source code up here.
