Fresh hacks every day
[Sebastian] is trying to improve the responsiveness of an electric keyboard. He was unsatisfied with the lack of adequate sensitivity to keystroke. The first step in his process was to measure how fast the quickest keystroke actually is. By setting up an LED and phototransistor and taking some measurements he found that sampling at 1 kHz would be more than … Read the rest
[Ben Kurtz] is doing a little WEP cracking but in a bit of a different way than we’re used to. WEP cracking makes us think of war driving; driving around with your laptop open, looking for WiFi access points, and stopping to run some software when you find them. [Ben's] way is similar but different in one key way, he’s … Read the rest
[Alexsoulis] needed to burn the Arduino bootloader to a slew of ATmega328 chips. Instead of sitting there and plugged the chips into a programmer one at a time, he build a robotic microcontroller programmer.
It starts with the DIP package microcontrollers in a tube, with a servo motor to dispense them one-by-one. An arm swings over and picks up … Read the rest
[Dogbert] took a look at the security that goes into BIOS passwords on many laptops. He starts off with a little background about how the systems work. People are bound to forget their passwords, so when you enter a wrong one three times in a row you get a message similar to the one above that locks you out until … Read the rest
Here we are with Episodes two and three (aka, NYC Resistor part one and two) completing the Take on the Machine Hackerspace challenge we mentioned a while back. For the challenge NYC Resistor took an old style slot machine and converted it into a drink mixing deviant; even making the device post a Tweet for every drink. However, it … Read the rest
[John Boxall] finds himself doing a fair amount of projects that require a realtime clock. He does fast and frequent prototyping, usually using the Freetronics twentyten which is an Arduino alternative that boasts a few features like a nice prototyping area, edge visible LEDs, and Mini USB. What is lacking, however, is a real-time clock. Instead of making another … Read the rest
[Mazvydas] shares with us, his cheap robot hand. He was inspired by this project, where someone used an Arduino and a glove with some flex sensors to control a pre-made hand. He wanted to go a little more DIY though. He chose a picaxe microcontroller and constructed the hand himself out of twine, some plexi-glass, and some rubber … Read the rest
