Fresh hacks every day
Since we're not high-end camera aficionados it was a surprise to us that the hot shoe that allows a camera to interface with a flash module has changed rather dramatically over the years. Apparently the interface used to be mchanical-electrical in that the camera would use mechanical means to connect two electrodes from the hot shoe. It didn't matter the voltages it was switching because the … [Read more...]
Ditch that fancy wide-format LCD monitor and go back to the days when animation was made up of moving frames played back by a specialized device. [Pieterjan Grandry] built this gif player which does just that. The frames of the animation are printed on a paper disk. When spun and viewed through a looking hole the same size as one frame an animated image is formed. If you know a thing or two … [Read more...]
In the quest for a diy laser cutter made from DVD burner parts (that hack's still in the works) this guy ended up with a junk box full of optical-drive leftovers. He put some of that surplus to good use by building this stroboscope. As the media spins, the white LED just out of focus in the foreground strobes to freeze the little black figure in the same place. The effect, as seen in the video … [Read more...]
Here at Hackaday the only thing we like better than giant whirling artistic desert based contraptions are interactive giant whirling artistic desert based contraptions. [Peter Hudston]'s Charon is no exception. Known for his strobe sculptures [Peter] has returned from a two year hiatus with possibly one of the craziest and nightmarish sculptures found on the deep playa. The work features a … [Read more...]
This water sculpture can stop drops of water in mid-air. This is accomplished by flashing LEDs to illuminate the droplets at just the right time. But it's not limited to blinky lights alone. The top of the frame has eight nozzles, each fed by its own pump. An Arduino controls the pumps and the lights making it possible to create different motion effects by adjusting how events line up. For … [Read more...]
Check out this slick strobe array for dance parties. Controlled by a DMX512 interface, only a small modification was necessary to get the strobes working. If you've played with a small commercial strobe light, you'll know there's a potentiometer to control the strobe speed. He simply soldered a relay after the pot. This allows him to tune them to be charged and ready for when the relay is … [Read more...]
Strobeshnik is a somewhat different twist on the hard drive clocks we've seen in the past. Though still technically using a POV effect, the Strobeshnik displays the numerals instead of a line. By altering strobe timing of an LED behind a platter with the numbers cut into it, he can display whichever number he wants. We think this is pretty slick. … [Read more...]
