Fresh hacks every day
[Vinod Stanur] is working with a mouse input and a microcontroller driven LED matrix. The mouse cursor is tracked inside of a window by Python and the resulting coordinates on the LED grid are illuminated. He calls it an LED matrix “Paint Toy” because one of the features he’s included lets the user create pixel art like in MS Paint.… Read the rest
[Vinod] just finished building a voice recorder and it turned out even better than he thought it would. The video after the break shows him recording what is surely one of your favorite songs from his cellphone and then playing it back. The audio quality does sound quite good for a project with very few components.
A PIC 16F877A makes … Read the rest
[Muth] added an auxiliary display to his motorcycle instrument panel. He started out prototyping with a PIC 16F877A which he used to access information through the ECM diagnostic connection. Once he had that working he found this tiny display which fits perfectly between the speedometer and tachometer. There’s a short demo after the break where you can see a past-30-minute … Read the rest
[Yosh] came through with a link to the Snake playing LED matrix that he read about in our links post from yesterday. It seems that [Arty Fart] actually built three of these in green, yellow, and red. You can see him throw one together (an 8-10 hour job) in the video after the break. In addition to playing Snake … Read the rest
[Amnon] is learning the hard way that water and electronics don’t always like to play nicely together. He’s been working on creating a swimming fish that uses three servos to flex a sheet of fish-shaped polycarbonate. This photo doesn’t really do the project justice but you can get a better idea of what he’s accomplished by watching the videos after … Read the rest
