This Double Sided Microcontroller Controlled PCB Exposure Box uses a PIC 16f268 to time the exposure LEDs on for the entered exposure duration. You can select if you are doing a single sided or double sided board, then you set the exposure time you need. After this you just sit back and relax while your board is getting perfectly exposed. We have seen some exposure boxes before including this UV
This project by Robotics / Electronics / Physical Computing is an Airsoft RC Tank that Tracks the Enemy and Fires at them. Using IR LEDs on a target and a LEGO NXT brain the robotic tank drives around looking for the target. The tank doesn’t hit anything because it has an ultrasonic sensor in the front to sense the distance from objects. A Wiimote camera is used to look for
We have seen quite a few Nintendo Nunchuck hacks. The Nunchuck is a great piece of hardware for hackers since it packs lots of great sensors and switches in a nice looking, functional package and best of all they are cheap! The LVL1 Hackerspace decided to use a Nunchuck in a Fire Breathing Pony project that they brought to Maker Faire Detroit. There isn’t much details on the build yet
I remember before small CNC machines became popular I would see engraving pantograph system in all of the small engraving stores in the mall. They had large letter blocks which could be traced and the result would be a tiny accurate letter engraved onto whatever was under the cutting head. When I first saw the picture of this Electronic Sketching Pantograph by Laura Harris I was wondering what the wires
Marklar who is a senior member over at the Arduino forums converted a junked radio into a fantastic RGB LED controller. When he looked inside an old radio to salvage some IR parts he spied a Rotary Encoder, these are a bit tricky to setup for the first time but they are great when you are done. For those who aren’t sure what a rotary encoder is, be sure to
There are lots of LED flashlights around but there is a Kickstarter for this new LED Packlight. It looks to be very versatile and could be helpful in so many ways. I am thinking my ideal application for this light would be a camping trip, it could be used in the car as a map light, stuck on the metal of the car to assemble the tent at night, hanging
Erica Kane has developed an Open Source DIY Automated LED Stair Lighting system. It uses an Arduino Pro Mini as the brain and a M5451 LED Display Driver to power the LEDs. She used PING sensors to detect when someone enters the stairwell. Currently the lights just turn on one at a time but that is all customizable by changing a bit of Arduino code. If you are looking for
