Clove 2 Glove For One Handed Input

July 12, 2008 by 23 Comments


[Christopher Mitchell] (previously on Hack a Day) has come up with a rather interesting input device. The Clove 2 glove is a Bluetooth data input interface. The goal is to be able to “type” without the use of a traditional keyboard. Key strokes are achieved through finger movements. Your computer simply sees this as a Bluetooth HID device and some software translates it for you.

While it may seem confusing, he’s designed it to be very similar to typing on a keyboard. Each finger movement or combination is a key stroke. Just like typing on a regular keyboard, there are modifying strokes such as ALT or shift that effect others. Most common used keys require the least combinations of finger movements.

DIY HID Ballast

June 10, 2008 by 16 Comments


HID lights have a major power consumption and lumen output advantage over halogen lights. Unfortunately the ballast component isn’t very cheap. [brian]’s been building his own ballasts for his mountain bike. We couldn’t find any more info on his design, but we did find some interesting stuff. This document lays out the requirements for a ballast. Here’s an older HID ballast design to get rolling. Keep in mind that the lamp requires high voltages – don’t play with it unless you know what you’re doing. If you’d rather use off the shelf components, check out the HID dive light we wrote up a while back. It uses a fairly inexpensive ballast/lamp combo.
