But isn't this just begging the question?
If hobbyists can make use of it, then by definition it's a hobbyist venture. Bringing down size, cost, and complexity is exactly the path by which so much has become available to hobbyists these days.
Wasn't that long ago that a laser cutter, heaven forbid a 3d printer, was for pro shops only.
- gh02t 9y agoYeah but I think there is a fundamental difference here. A 3D printer enables you to do things you can't do otherwise (fabricate custom mechanical parts). A pick-and-place enables you to do stuff you can already do with tweezers except in the most extreme cases. And likely do it faster than with a pick-and-place, because they require quite a lot of work to configure. Edit: a good analogy is a homebrewer putting caps on beer bottles. You can do it by hand with a simple tool pretty easily - even capping 100 bottles at once is no sweat, really. It just doesn't make sense to have an automated bottle capping machine even if it was cheap, because it takes up space and ends up taking more effort to set up for a small run than it saves you. Pardon the pun, but the bottleneck lies elsewhere.
- birdman3131 9y agoAs far as bottle capping machines you end up having to make custom handling parts and those are not cheap. (The chucks alone run several hundred dollars each.) Then the parts to guide the bottles through the machine have to be made specific to the bottle diameter and height. this costs several grand. There is still a lot of adjustment even after this. And if you want to change bottles or caps then outlay a ton more cash. Capping them by hand despite the time and effort makes sense until you can afford a significant outlay in cost. (I work for a machine shop that makes handling parts and retrofits capping/filler machines for the bottling industry. I don't fully know our prices but most of them would be far outside the range of any hobbyist starting out.)

- imtringued 9y agoA "reel" library (tape library) is going to be very expensive.
- hoopladler 9y agoWell, you can actually do stuff a 3d printer does by other means. It just typically requires more skills, and often more equipment. I think your analogy falls down because an automatic bottlecapper does the same thing as you'd normally do by hand. The difference for me is that a pick-and-place machine is an enabler. It would enable hobbyists to take on large-scale, distributed electronics projects - for which, right now, assembly time is normally the bottleneck. If all hobbyists were solely interested in producing consumer-style devices, like bad versions of phones, or home-automation systems, then a pick-and-place machine wouldn't be a good idea for anyone. But there are actually lots of hobbyists that do stuff like data logging, where assembly time is a major problem.
- gh02t 9y agoThere are hobbyists who might want to, I don't dispute that, but what I'm saying is there aren't enough. You need a pretty big critical mass before the economics start to make sense and something like what happened with 3D printers becomes possible. Projects at the scale you're talking about take a massive investment of time and skill independent of how long it takes to assemble boards, putting them out of reach of the vast majority of people simply because they don't have the time. Not to mention the cost of such a project; if you can afford to invest a thousand or more dollars in a hobby project then you can probably afford the tools you need to do it, too. Maybe I'm underestimating and there are tens of thousands of people out there wanting to build complex data logging networks with hundreds of nodes just for fun or some other equally ambitious project, but I doubt it. > I think your analogy falls down because an automatic bottlecapper does the same thing as you'd normally do by hand. That was my point. A pick and place does the same thing you'd normally do by hand with a pair of tweezers in about 10 minutes for a board of moderate complexity. Doing surface mount work by hand with tweezers is pretty easy. The only thing a pick and place enables is for you to do things at a large scale, because they have a substantial overhead to use that you only start to recoup around 50-100 units or more. Now, if we had some revolutionary device that you could set up in 10 minutes to feed dozens of parts and cost $500 then hell yes, I'd want one too. But I don't think that's possible at present no matter any economies of scale or design optimization, because a pick and place is actually quite a complex machine by simple necessity. Not to mention that placing parts is only part of it - you still have to fabricate and drill the boards, load the machine, clean up any mis-places, reflow them in an oven, manually place any through hole or awkwardly shaped components and solder them, cut the boards, test them, program them, mount them, etc. A pick and place would definitely save you some time if you really want to do such a large project, but by itself I don't think it's gonna be enough to really make it accessible to an individual in their free time. I'm not disputing that they would be beneficial, just that they make sense for an individual working in their free time. Especially when you consider that contract manufacturing isn't that expensive, though it does come with its own set of hassles.
- HeyLaughingBoy 9y agoNot really. The tool isn't the issue. If a hobbyist wants to play with a Pick & Place, go for it. My point was that the typical hobbyist isn't going to be manufacturing 1,000 units of anything, no matter how cheap is to do. Once you get into those numbers, it's far more likely to be a (small) business venture.
