Fresh hacks every day
When [Tom] got tired of the large size of his Microsoft Comfort Curve 2000 keyboard, he decided to hack a recently acquired Apple Adjustable Keyboard for use with Windows. After removing the ancient ADB based control board from the Apple keyboard, he was able to map the keys and transplant the Microsoft keyboard's USB control board into the Apple keyboard. After soldering the control board into … [Read more...]
Every year [Len Bales] designs and builds a new clock. His 2006 clock runs on the classic Intel 8008 microprocessor. The design is definitely not for the faint of heart, but he includes all code, diagrams and a good description on his site. The project is an interesting look into the not-so-distant past of computing. While the function of the project is a clock, it is actually a fully programmable … [Read more...]
Over at SpriteMods, [sprite_tm] realized that a microcontroller could be used as a boost converter to power itself. A boost converter steps up voltage from a battery by switching the output of a coil. First, it is tied to ground so a magnetic field can build up in the coil. It is then released as a higher voltage than the input. Normally dedicated chips do this at an incredibly high frequency, but … [Read more...]
Here is a classic project used to increase wireless signal strength. Cantennas focus using a waveguide very much like a magnifying glass focuses light. [Robert] made a Natural Light beer cantenna, pictured in the upper left. His approach used three beer cans, a paper towel holder, and a shower curtain rod. On the tipline, he noted a signal boost from 11Mbps to 54Mbps. This is certainly something … [Read more...]
This tiny bot wants to go inside your body. That's right, it was designed to travel through veins. The little bot has no on board propulsion system. It is controlled by a magnet outside the body. See those little spines? Those straighten out to keep the bot in place when it isn't supposed to move. Creepy right? In all the articles we've seen on this bot, there aren't any details about what … [Read more...]
We would like you to meet PR2. Made by Willow Garage, PR2 is a platform for research into robotic programming. The bot itself is simple compared to some of the humanoid bots we see, but its behavior is quite complex. In the video above, you see PR2 completing milestone 2 of its development. This includes navigating an office with closed doors and plugging itself into a standard wall outlet for a … [Read more...]
