CNC milling custom 40DP timing belt “gears”/pulleys
Woo, it’s been a long time since I messed with pick & place stuff. Bad Tim. An irritation I have been having is making everything work using reliably sourceable, off-the-shelf parts (not lucky eBay/surplus finds). In particular I’ve found small “tin can” stepper motors are hard to source in small quantities repeatably, and once you…

Not Dead
Really! Just busy with some real-life stuff, namely wedding related and home renovations. I haven’t forgotten about this pick & place stuff! Lately I’ve been spending most of my project time on getting Mosquino toward an official 1.0 release. The rev2 boards just came in, so once all the parts are in I should have…

Motorized SMT tape-and-reel feeder for DIY pick & place
Despite the impact of work, wedding planning and Super Metroid fan-hacks (not necessarily in that order ;-) on my freetime, my scheme to design a DIY-able open pick & place system is starting to come along. So far, there is a proper vacuum placement head, a rough idea of what the software architecture might look…

Tape Sprocket Creator
This is a free (open source) Python script for creating feeder sprockets for e.g. perforated tape or film advance. I wrote it for myself to generate SMD tape-and-reel feed sprockets, but it might also be useful for making replacement sprockets for 8/16/35mm film, microfilm and paper-tape systems whose original reader hardware no longer exists or…

Reversing an aquarium pump
An aquarium air pump can be used as an inexpensive source of low vacuum with a small amount of tweaking. Supplies needed are: The air pump Screwdriver (usually) to open the air pump Hose barb (your favorite size) for vacuum inlet Drill Glue (e.g. RTV/caulk, epoxy, etc.) Of course, you could convert one by sealing…

Pick n place head update
This is a quick follow up to the pick & place head article, in which I actually build the darn thing :-) As in, not just fit-test the parts together and take a picture, but actually pick and place some stuff with it. I’ve been busy/lazy, so not too much to show in terms of…

Image segmentation for PnP optical placement
Quick ‘n dirty (but working!) image segmenter for randomly-strewn part identification. About 1 page worth of scripting takes an image of objects on background, determines which part is the background, determines the outside contour of each object and numbers each as a separate object. Now that it’s known where to look for one specific object,…

Pick ‘n Place Head
This weekend I got some parts in and put together a preliminary placement head for my open-source pick ‘n place project. My requirements are that it be buildable with off-the-shelf parts (ideally same-source, to save on shipping) and no special equipment, allow +/-180 degree rotation while maintaining an undisturbed vacuum, and support interchanging of the…
