Collaborate Disseminate
Toys are great for keeping the kids amused at play time, but oftentimes its difficult to get them to understand the importance of tidying up after themselves. It would naturally be ideal to have some manner of robot to help in this regard, and [Paco Garcia] might just be leading …read more
There’s something mesmerizing about delta robots. Whether they are used at a stately pace for a 3D-printer or going so fast you can barely see them move in a pick and place machine, the way that three rotary actuators can work together to produce motion in three axes is always a treat to watch. Especially with a delta robot as small as this one.
[KarelK16] says this is one of those “just because I can” projects with no real application. And he appears to have been working on it for a while; the video below is from eight years ago. …read more

Would you believe that you can take a cheap 3D printer and easily convert it into a full function pick and place machine to help assemble your PCBs? No? Well good, because you can’t. A real pick and place needs all kinds of sensors and logic to identify parts, rotate them, make sure everything is aligned, etc, etc. There’s no way you could just bolt all that onto a cheap 3D printer, and let’s not even talk about the lack of closed loop control.
But if you have a very specific use case, namely a PCB that only has a …read more

Surface mount is where the action is in the world of DIY PCBs, and deservedly so. SMDs are so much smaller than through-hole components, and fewer holes to drill make surface-mount PCBs easier to manufacture. Reflow soldering is even a snap now thanks to DIY ovens and solder stencils you can get when you order your boards.
So what’s the point of adding another stencil to the surface-mount process? These component placement stencils are [James Bowman]’s solution for speeding up assembly of boards in production runs too small to justify a pick and place robot. [James] finds that placing small …read more

It’s a Holy Grail among hackerspaces, the possession of a pick-and-place machine. These robotic helpers for placing surface-mount components on PCBs are something of a gateway to electronic production, but they can carry a fearsome cost. Happily for the cash-strapped would-be electronic manufacturer, it is possible to build a pick-and-place for yourself. [Mcuoneclipse] has demonstrated this with a rather impressive build that works with the freely available OpenPnP software.
Superficially it shares much with what you might expect from a small CNC mill, in that it has a frame made from extruded aluminium that carries rails that trace an X …read more
When something needs improving, most hacks often make a small tweak to address a problem without changing how things really work. Other hacks go a level deeper, and that’s what [Felix Rusu] did with his 3D printed magnetic holders. Originally designed to address a shortcoming with the PCB holders in his LE40V desktop pick-and-place machine, they turned out to be useful for other applications as well, and easily modified to use whatever size magnets happen to be handy.
The problem [Felix] had with the PCB holders on his pick-and-place was that they hold the board suspended in midair by gripping …read more

[Amitabh] was frustrated by the lack of options for controlling air pressure in soft robotics. The most promising initiative, Pneuduino, seemed to be this close to a Shenzhen production run, but the creators have gone radio silent. Faced with only expensive alternatives, he decided to take one for Team Hacker and created Programmable Air, a modular system for inflatable and vacuum-based robotics.
The idea is to build the cheapest, most hacker-friendly system he can by evaluating and experimenting with all sorts of off-the-shelf pumps, sensors, and valves. From the looks of it, he’s pretty much got it dialed in. Programmable …read more
For his Hackaday prize entry, [Daren Schwenke] is creating an open-source pick-and-place head for a 3D printer which, is itself, mostly 3D printable. Some serious elbow grease has gone into the design of this, and it shows.
The really neat part of this project comes in the imaging of the part being placed. The aim is to image the part whilst it’s being moved, using a series of mirrors which swing out beneath the head. A Raspberry Pi camera is used to grab the photos, an LED halo provides consistent lighting, and whilst it looks like OpenPnP may have to …read more

The cool kids these days all seem to think we’re on the verge of an AI apocalypse, at least judging by all the virtual ink expended on various theories. But our putative AI overlords will have a hard time taking over the world without being able to build robotic legions to impose their will. That’s why this advance in 3D printing that can incorporate electronic circuits may be a little terrifying, at least to some.
The basic idea that [Florens Wasserfall] and colleagues at the University of Hamburg have come up with is a 3D-printer with a few special modifications. …read more

With the fine work needed for surface-mount technology, most of the job entails overcoming the limits of the human body. Eyes more than a couple of decades old need help to see what’s going on, and fingers that are fine for manipulating relatively large objects need mechanical assistance to grasp tiny SMT components. But where it can really fall apart is when you get the shakes, those involuntary tiny muscle movements that we rarely notice in the real world, but wreak havoc as we try to place components on a PCB.
To fight the shakes, you can do one of …read more
