With the advent of cheap PCB fabrication, (relatively) easy to use layout tools, and a whole host of prototypes for nearly any device imaginable, the age of custom circuits is upon us. The tools to make these custom circuits, though, are usually hilariously expensive or simply unavailable to all but the most resourceful hackerspace. It would be great if every workshop in the country had a pick and place machine, and the $300 Pick and Place / 3D printer would be a great way to introduce this tech to millions of electronic tinkerers around the world. It also makes for a great entry to The Hackaday Prize.

The basic design of this machine is a delta bot. This is a wonderful choice over a Cartesian bot; deltas are faster and can have higher acceleration, a great thing to have if you want to throw together a few boards quickly. Although the configuration looks a little inverted as compared to other 3D printer delta bots, there’s a reason for this: the design was simulated with evolutionary algorithms and statistical tests to find the best geometry for the machine. The completed machine should be able to place 0201 components; anything smaller would be called dust.

The software hits all the marks, using OpenCV for image processing, ARM boards for motor control and computational tasks, and a good bit of mechanical and pneumatic work to suck up the parts. They’re even working on a 3D printed tape feeders. Now a component often overlooked when looking at the total cost of pick and place equipment is essentially free.

It’s awesome work, and even if they don’t win The Hackaday Prize, it’s still something every hackerspace should have. Now if someone would only crack the through-hole plating problem…

The project featured in this post is an entry in The Hackaday Prize. Build something awesome and win a trip to space or hundreds of other prizes.
