Fresh hacks every day
[Fezoj] likes to play around with microcontrollers and decided that he wanted to try a Bus Pirate as a new tool in his adventures. Since it’s open hardware he had his own board made and populated it himself. The trouble is, he works only with AVR chips and doesn’t have a PIC programmer. No problem, he figured out how to … Read the rest
Here’s the latest project from [Niklas Roy's] workshop. Lumenoise is an audio synthesizer controlled by drawing with a light-sensitive pen on a CRT television.
The pen is a self-contained module which connects to the TV via audio and composite video RCA plugs. Inside the clear pen housing you’ll find a microcontroller which generates the audio and video. The business end … Read the rest
[Arko] was compelled to purchase an iclicker to use in some of his college courses. It’s similar in size to a television remote control except it only has six buttons and it communicates via radio frequency instead of infrared light. The idea is that classrooms have a base station that the instructor uses, and he or she can ask questions … Read the rest
Hackaday contributor [Nick Schulze] popped out an impressive set of LED headgear for a hat-themed party.
[Nick] is no stranger to working with LEDs. Previously he built a blue 8x8x8 cube something like this other 512 node full color version. He had a bunch of LEDs left over from that project and decided to put them to good use.… Read the rest
What could be better than a low-res black and white photograph printed instantly on paper that will yellow and crumple over time? Wow, we really need to work on our sales pitch. But all kidding aside, we love the idea that [Niklas Roy] came up with in order to build this thermal printing camera.
His Picasa album has two … Read the rest
[Niklas Roy] sent in a project he just completed called PING! Augmented Pixel. At first glance the entire build is just a plain jane retro video game stuffed into an ATmega8 but looks can be deceiving. The video game is actually an augmented reality device that inserts a pixel into a video feed. The bouncing pixel can be manipulated … Read the rest
[Q] is an Electrical Engineer who works in an industrial setting. He frequently uses Programmable Logic Controllers at work but had never built one himself. He decided to undertake the project at home and managed to build a PLC that outputs 120V AC or 12 V DC and has optoisolated inputs.
On the circuit board you’ll find an ATmega8 … Read the rest
