Autonomous Helicopter Works Like A Wii Remote

[Jack Crossfire] took one of those inexpensive indoor helicopters and made it autonomous. He didn’t replace the hardware used for the helicopter, but augmented it and patched into the remote control to make a base station.

The position feedback is provided in much the same way that the Wii remote is used as a pointing device. On the gaming console there is a bar that goes under the TV with two IR LEDs in it. This is monitored by an IR camera in the Wii remote and used to calculate where you’re pointing the thing. [Jack’s] auto-pilot system uses two Logitech webcams with IR filters over the sensors. You can see them mounted on the horizontal bar in the cutout above. The helicopter itself has an IR LED added to it that is always on. The base station follows this beacon by moving the cameras with a pair of servo motors, calculating position and using it when sending commands to the remote control’s PCB.

Don’t miss the demo video of the rig after the break.

USB Ports Hidden Inside Gaming Mouse

October 2, 2010 by Mike Szczys 26 Comments

[Gigawatts] built a pair of USB ports into his mouse and there’s enough room to plug-in small USB drives and dongles. After seeing Thursday’s storage mouse hack he decided to tip us off about the post.

He started with a Logitech G5 gaming mouse. The wireless version of this mouse has a battery pack, but on the corded version this space is used for a weight cartridge. Since he didn’t really care about that feature he ditched the weights, added a USB hub inside, and positioned the dual ports as seen in the photo. The void is deep enough for the mouse to function normally while hosting medium to small-sized devices. This is a fantastic solution that’s at least as impressive as Apple adding USB ports to a keyboard. We’d love to see it as a factory option.

Woot Lights And Mice Transplants

September 29, 2010 by Jakob Griffith 6 Comments

[Nathan Long] sent in two fairly simple mods he’s been working on. The first is the control of Woot-off Lights via LPT port. A computer checks Woot for the Woot-off logo, and if the logo is spotted, on go the lights. It’s really just a twist on the LED/Arduino email message system, but the creativity is nice.

His other modification is the stuffing of a Microsoft Intellimouse inside of a Logitech Wingman. With the goal of giving the old PS/2 mouse USB capabilities and removing the terrible ball. For those that are asking themselves “why bother? Terrible ergonomics, no scroll wheel, etc.” [Nathan] claims it’s for Quake 2 nostalgia, to each their own we suppose.

Portable Squeezebox With Serial

March 2, 2010 by Jakob Griffith 14 Comments

The Squeezbox media streaming systems are compact Linux WiFi enabled radios that let you stream your collection anywhere,so long as you have an AC or USB outlet nearby. But [Achim Sack] wanted to stream his collection from anywhere with no wires attached (translation). Some poking and prodding revealed a connector actually designed for a battery and serial, but no commercially available battery yet.

The system requires a temperature sensor and if you want serial, a USB converter, but overall a simple process that could be done in an afternoon. Giving your box ~10 hour of life and even fits inside of a back compartment.
