Arduino Music Box Turns Stuffed Animal Into TV Personality

Childlike imagination is a wonderful thing. The ability to give life to inanimate objects and to pretend how they’re living their own life is precious, and not for nothing a successful story line in many movies. With the harsh facts or adulthood and reality coming for all of us eventually, …read more

Rotary Controller Dials in PC Volume

As wonderful as mechanical keyboards are, most of the pre-fab and group buy models out there have zero media controls. If you want rotary encoders and OLED screens to show what function layer you’re working in, you’ll probably have to build your own keyboard from the ground up.

Hackaday alum …read more

Matrix of Resistors Forms the Hot Hands Behind This Thermochromic Analog Clock

If you’re going to ditch work, you might as well go big. A 1,024-pixel thermochromic analog clock is probably on the high side of what most people would try, but apparently [Daniel Valuch] really didn’t want to go to work that day.

The idea here is simple: heat up a …read more

Alexa, Shoot Me Some Chocolate

[Harrison] has been busy finding the sweeter side of quarantine by building a voice-controlled, face-tracking M&M launcher. Not only does this carefully-designed candy launcher have control over the angle, direction, and velocity of its ammunition, it also locates and locks on to targets by itself.

Here comes the science: [Harrison] …read more

The Three Shell Mystery Finally Solved!

While we certainly acknowledge the valuable contributions of the open hardware community that help to mitigate the coronavirus crisis, we are also looking forward to the days when people start going back to building other things than 3D-printed face shields, pandemic trackers, and automatic soap dispensers. However, this handwash timer …read more

Pump Up The (Windows) Volume With Physical Sliders

For as long as we can remember, Windows has provided a mixer that breaks out the volume level of every applicable application into its own slider-controlled lane. But navigating to these controls is non-trivial, especially if you’re in a hurry to silence someone on team speak. You have to stop …read more
