Fresh hacks every day
[Bob] has a USB page hit counter that uses an ATtiny25 to run a MAX7219 which drives eight 7-segment displays. It is easy to implement USB on an AVR using just firmware, eliminating the need for any USB to RS232 conversion. The host software is written in Delphi and sits in the Windows tray. The code examples seem simple enough … Read the rest
The RepRap project, which is a printer that can make components using rapid prototyping technology, and it is designed so that it can eventually self replicate. Has released a new breakout board for the Sanguino that provides access to all the pins as screw terminals. The Sanguino is an Arduino compatible board based on the ATmega644P chip. You … Read the rest
We wrote about [Chris Anderson] before when he released the Arduino based autopilot. He has since crashed his first Predator UAV, due to an underpowered motor and poor control of the v-tail only steering. He has since released a pro version of the autopilot controller, and is modifying this UAV Predator drone kit to work with it. One … Read the rest
[Joe L] sent in the Arduway on the tipline. It is a robot made of Arduino and Lego NXT components based on the Segway. A software library to control LEGO NXT motors and a few sensors he used is available on SourceForge. This robot does a good job of balancing itself while moving forwards and backwards.… Read the rest
This PICBASIC complex LED matrix solution was developed by [Olivier de Broqueville] to drive a matrix of LEDs. Using some cheap transistors, common red LEDs, and a PIC16F628, he is able to drive a 6×6 LED matrix. This project is very well documented and has everything available including: circuit board layouts, schematics, PICBASIC source, VB computer interface program, and parts … Read the rest
If you weren’t looking forward to trying to find a NES Four Score just to rip connectors out of it or were reluctant to cut the ends off your NES controllers and use different connectors for your NES hack, you’re in luck. Parallax has released an NES controller connector (7-pin, male) that is compatible with the Nintendo controller. They also … Read the rest
Normally case mods are all show and no go, but [Fredrik Perman] and [Michael Stabile] took their old render farm and made it a working showcase for the front lobby. This is a perfect combination of function, beauty, and practicality. It is a great conversation piece, allows easy working access, and provides a tremendous space savings in one … Read the rest
