Not Your Typical POV Clock

Persistence of vision displays are fun, and a natural for clocks, but they’re getting a little Nixie-ish, aren’t they? There are only so many ways to rotate LEDs and light them up, after all. But here’s something a little different: a POP, or “persistence of phosphorescence” clock.

[Chris Mitchell] turned the POV model around for this clock and made the LEDs stationary, built into the tower that holds the slowly rotated display disk. Printed from glow-in-the-dark PLA, the disk gets charged by the strip of UV LEDs as it spins, leaving behind a ghostly dot matrix impression of the time. …read more

Mouse Mis-Clicking? We Got You.

A mouse with malfunctioning buttons can be a frustrating to deal with — and usually a short leap to percussive maintenance. Standard fixes may not always last due to inferior build quality of the components, or when the microswitch won’t close at all. But, for mice that double/triple-click, will release when dragging, or mis-click on release, this Arduino-based hack may be the good medicine you’re after.

Instructables user [themoreyouknow]’s method cancels click malfunctions by latching the mouse’s controller switch trace to ‘on’ when pressed, keeping it there until the button normally closed contact closes again completely. Due to the confined …read more
