Flip-dot displays look and sound awesome. At least to all of us electronics geeks who dumpster dive for second-hand panels to add to our collections of esoteric display technology. But …read more Continue reading Flip-Dots Enter the Realm of Fine Art
We are used to flipdots, single mechanical pixels that are brightly colored on one side and black on the other, flipped over by a magnetic field. Driving the little electromagnets that make them work is a regular challenge in our community. [Johan] however has a new take on the flipdot, …read more
There are a variety of means by which numbers can be displayed from an electronic circuit, and probably the most ubiquitous remains the seven-segment display. Take seven LEDs, lamps, LCDs, VFD segments or mechanical flip-dot style units in the familiar rectangular figure eight, and your microcontroller or similar can display …read more
[Irene Posch] is big into knitted circuits. And while most of the textile circuits that we’ve seen are content with simply conducting enough juice to light an LED, [Irene]’s sights are set on knittable arithmetic logic units (ALUs). While we usually think of transistors as the fundamental building-blocks of logic circuits, [Irene] has developed what is essentially a knit relay. Be sure to watch the video after the break to see it in construction and in action.
The basic construction is a coil of conductive thread that forms an electromagnet, and a magnetic bead suspended on an axle so that …read more
