Vector based displays were used for arcade games in the ’70s and ’80s. A typical CRT uses raster graphics, which are displayed by deflecting a beam in a grid pattern onto a phosphor. A vector display deflects the beam in lines rather than a full grid, drawing only the needed vectors. Perhaps the best known vector game is the original … Read the rest
This is [Wpqrek's] Commodore 64 modified to go on the road with him. The elderly machine has a special place in his heart as it was what he learned to code on. He performed a series of hacks which house everything necessary to use the machine inside the original case.
Obviously the hack that has the most effect when … Read the rest
A 2:1 gear reduction slows down a spinning shaft to half speed and doubles the torque. Repeat this a few times, and you’ve got a ludicrous amount of torque moving too slowly to see with even precision instruments. That’s the idea behind [Jeshua]‘s project, a Printed Machine partially embedded in a block of concrete.
[Jeshua]‘s build is a replica of … Read the rest
When you’re building one of the best homebrew computers ever created, you’ll also want a great case for it. This was [Simon]‘s task when he went about building an enclosure for his Kiwi microcomputer.
The image to the left doesn’t make this look like much, but inside of the cardboard vending machine lives a clever Rube-Goldberg device. The video after the break gives a look at the inner workings to show how a quarter manages to dispense a full can of Coke. But that’s about all the detail we get on the project.… Read the rest
Back in 1991, a young [Backwoods Engineer] and his new wife went to a Valentines day get together. One of the conditions of the shindig was having the guys make – not buy – a Valentines day card. Go big or go home, he though, and after a few days he had a talking Valentines day card that would become … Read the rest
We’ve seen scores of floppy drives play music, but never before have we seen a project as clean as [Rupert]‘s Moppyduino. It’s an Arduino-based board that controls the stepper motors in six separate floppy drives, coaxing them in to playing music from a MIDI file.
The Moppyduino is more than just a convenient way to control the stepper motors … Read the rest
