Stop Motion with the Time Glove

What do you get when you put an ultra-bright LED in the palm of a glove, and strobe it controlled by an accelerometer? A Time Control Glove! In creator [MadGyver]’s own words, it’s “just a stroboscope with frequency adjustment” but the effect is where all the fun is.

The Time Control Glove uses the stroboscopic effect, which many of us have seen used in timeless water drop fountains where the strobe rate makes drops appear to change speed, freeze in place, and even change direction. [MadGyver] made the entire assembly portable by putting it into a glove. An on-board accelerometer toggles the strobe in response to a shake, and the frequency is changed by twisting the glove left or right. The immediate visual feedback to the physical motions is great. The whole effect is really striking on the video, which is embedded below.

Schematics and bill of materials are available on GitHub. Brilliant work! And while we’re discussing the stroboscopic effect, find out how it can be used to tune guitar strings.

  1. Awesome implementation of PWM strobe, refine that into a a compact PCB design/enclosure and you’ll make a killing selling these to kids next christmas. time gloves are the next fidget spinner!!!!

      1. bah! concern trolling, pwm is used in a load of consumer electronics, once the frequency is high enough the mind simply percives it as a continious light source, nowhere photosensitive ep associated freqs.

  2. “What do you get when you put an ultra-bright LED in the palm of a glove, and strobe it controlled by an accelerometer?”

    Burns. You get a burnt palm because you decided to use your hand as the heat sink for that big LED. I’m guessing that this device is good only for short uses with long intervals in between for cooling. Cool project otherwise, though not something an epileptic like me would have much use for.

    1. ” I’m guessing that this device is good only for short uses with long intervals in between for cooling.” – The whole point of a stroboscope is to pulse at a very low duty cycle.

  3. You did a nice job getting your fine control algorithm to use the accelerometer so well, and the ‘superhero’ feel of the video is really cool. Nice hack! The point about that LED without a heatsink though is valid if someone is going to be using this for real.

  4. It’s the TMD from Singularity! “I wonder if they’ll take his arm this time.”

    In other notes I think my middle school science teacher would have given a lot to have one of these. Even for math education talking about modular arithmetic this would be pretty cool.

  5. Roughly a second after getting to the github page for this project I mashed BUY on everything I’d need to make my own. I’m going to give it a try and see how it goes! Maybe add an audio feedback as well, hmmm…

  6. Now, we can FINALLY hack time like Hackerman and go back to meet those two hot viking chicks – Barbariana and Catana – that helped Kung Fury take out Hitler! This is gonna be so RAD!
