[Jeff] says that designing your own 6502 computer is a rite of passage, and he wanted the experience. His board can accept a real 6502 or the newer CMOS variant that is still available. There are a few modern conveniences such as USB power and provisions for using a USB serial port. We are spoiled today with […]

Just when you think you’ve seen every possible way to play the piano, [Alessandro Perini] came up with a new one. In this piece, written for the percussionist [Irene Bianco], hand-held motors become a tangible interface between composer, electronic music equipment, and the performer. The performance involved ten small disc motors, held above the strings by

Sometimes, the best hifi gear is the gear you’ve already got. This is particularly the case in the cassette world, as high quality decks are long out of production. [Nick] liked his current rig, but wanted to be able to use it with a remote from across the room. Naturally, he set to hacking the feature

There is a boring part of every computer introduction class that shows how a computer is made up of input, output, and processing. Maybe it wouldn’t be so boring if the input device was a nunchuck. [Brian Lough] thinks so and he belligerently asserts that nunchucks are the best input device ever. With a simple connection
ARDUINO LEARNS THE MARTIAL ARTS WITH NUNCHUCKS INPUT DEVICE Continue Reading
Farkle is a classic dice game that only requires 6 dice and a way to write down scores based on the numbers rolled. Even so, this type of game isn’t inherently portable — it would be fairly difficult to play on a road trip, for instance. [Sunyecz22] decided that Farkle would make an excellent electronic game
HANDHELD FARKLE REALLY SPARKLES Continue Reading

Acrosser Technology has recently released a brand new entry-level 3.5” single board computer (SBC). This new AMB-BT19S1 single board computer is powered by an Intel Bay Trail SoC. It features 8GB RAM, dual display support, plus SATA, mSATA, mini-PCIe, serial, USB 3.0, and GbE ports. As the SBC market has already seen newer Atom processor families such as Cherry Trail, Braswell,

In this tutorial we’re going to play with a gesture sensor (APDS-9960) and a neopixel ring to learn how to combine them both using an Arduino UNO. The end product will respond to left – right gestures by animating led movement right or left, and to up-down gestures by changing leds color. In the next
Controlling a Neopixel Led Ring With a Gesture Sensor Continue Reading
Useless machines are generally built as a fun pastime, as they do nothing of value by their very definition. The most popular type generally involves a self-cancelling switch. However, there’s plenty of other useless machines to build, and we think [Jeffery’s] build is particularly creative. The build consists of an XY gantry that moves a standard
MOUSE-CONTROLLED MOUSE CONTROLLER IS SILLY, BUT COULD BE USEFUL Continue Reading
