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.

Cool… now add a microphone plus FFT and the time glove finds the objects frequency on itself.
Where I can get ppt presentation for this
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!!!!
Not to mention identifying photosensitive epileptics.
maybe it can be used as self defense, if the leds are blinding bright
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.
Shrink it loads if you got rid of the controller in favour of a 555
any IMUs output a signal that play nice with descrete analogue circuits?
That may be one of the hackiest hacks of all time, “Any sufficiently advanced technology is indistinguishable from magic.”
Love that quote.
Any technology distinguishable from magic is insufficiently advanced.
Completely impractical from basically every angle; it has no practical purpose and presentation is a rat’s nest of wires and electronics…
I love it!
No practical purpose? Stroboscopes are quite useful in inspecting all kinds of rotating equipment, and this seems easier to use than many currently available models.
its not a copper plate, it is anodized aluminium.
I too like to live dangerously. I have that exact fan and I also took the front guard off.
Great now I can be a Goa’uld.
Flicker reprogramming of the mind like the US and Russian governments.
“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.
This diode probably works only for 1% time, otherwise there would be too much motion blur, so I don’t think heat will be that problematic.
Helps the camera is 30fps
Probably make a good engine timing strobe
[ And the eye is about 10 ]
” 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.
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.
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.
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…
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!
Nah, some guy will end up hacking too much time and going back too far… Or worse, we’ll end up in some cartoon with a giant talking cobra.
I could time My engine with this!
That is so awesome! I’m so using this technique in some upcoming cosplay project.
