Fresh hacks every day
Pick and place machines are marvels of modern technology. They the can lift, orient, align and drop tiny electronic components onto a circuit board that is headed for the reflow oven. On an industrial scale they move so fast it’s a blur in front of your eyes, and they use imaging to ensure proper placement. But that kind of specialized … Read the rest
[Andrey Mikhalchuk] is trying to gather a base set of lab instruments. Specifically, he’s looking for hardware that will let him quickly filter solids out of a liquid. He first started by adding a cotton disk to a plastic funnel. It does the job, but when left to gravity it’s quite slow. He needed a way to speed up … Read the rest
[Tim's] been busy moving his pick-and-place build toward completion. We looked in on the first version of the vacuum head back in October. Since then he’s ditched the camera enclosure which allows for more light and better mounting. The tip has been replaced by one from a pair of vacuum tweezers, and the whole thing is now mounted … Read the rest
A little dumpster-diving let [Nick Skvarla] build his vacuum form machine for around $5. He pulled a vacuum cleaner out of the trash, which was tossed away because of a broken power plug. He put it into a box which had been sealed with spray foam and used a piece of pegboard for the top side of the enclosure. He … Read the rest
If you’re thinking of working with carbon fiber this guide should be a big help. The example is aimed at the automotive crowd but the principles transfer quite easily. Carbon fiber parts are constructed in a similar manner as fiberglass parts. A mold is covered in a release agent, the fibers are put in place and covered in epoxy. With … Read the rest
Here at Hackaday, we love it when people make home brew versions of elaborate, expensive, and technical equipment. By gathering up some coffee grounds, a balloon, some plastic tubing, and his lungs, [Carlos] has provided a good how-to on making your own coffee grounds robotic hand. Inspired by the U. Chicago, Cornell, and iRobot Collaboration we previously covered, he … Read the rest
[Alexsoulis] needed to burn the Arduino bootloader to a slew of ATmega328 chips. Instead of sitting there and plugged the chips into a programmer one at a time, he build a robotic microcontroller programmer.
It starts with the DIP package microcontrollers in a tube, with a servo motor to dispense them one-by-one. An arm swings over and picks up … Read the rest
