Though physical connectors in electronics are a boring subject, I do think its one of the "important" subjects that's commonly overlooked in electronics tutorials or books.
The fact is that there are many companies with many combinations of connectors and wires. Much as how a mechanical engineer has to inevitably learn the difference from a Philips head screw vs a Torx screw, electrical engineers will need to learn the difference between D-Sub, 0.1" pin headers, and other such connectors, as well as the pros/cons of each.
- zgluck 3y agoIm my experience: If there's one thing that makes sense to stock at your own little lab - to avoid waiting 1-3 days for getting that little thing that blocks that project you want to complete - it's a wide assortment of connectors. The rest can often be improvised in many ways using various microcontroller boards and voltage level converters etc that you'll probabably already have. The next most useful thing: A great assortment of fasteners! I think the thing to do here is to buy like M2x60 through M10x60 (A4 stainless, insex screws) and then use that nut-retapping trick to get that custom screw length that you need. "Do you mean cutting the screw to length with a nut on it, which then fixes the thread as you unfasten it?" Yes. Looks like I've been too chatty for today, HN's rate limiting brutally tells me to shut the fuck up. (The especially evil thing about this: You don't know until you press submit if your comment will be accepted or not. You could be writing the greatest comment of the week, but you have no idea if it will be automatically refused or not. You can only write and hope for the best. Fuck everything about that.)
- fest 3y agoGoogle is really not helpful in finding out what the nut-retapping trick is :> Do you mean cutting the screw to length with a nut on it, which then fixes the thread as you unfasten it?

- gtvwill 3y agoThis works well. I would suggest acquiring a triangle file and a blade file. You can fix cut thread ends easy and even some cross threaded sections. You don't always have nuts to go on threads items. E.g. when a rod is threading into a block.
- quenix 3y agoI might be a bit weird, but I find fitting proper connectors onto hardware super satisfying. I suppose I see a good connector as a good polish to an interface, similar to what might be found in software, for example. I get the same type of satisfaction that comes from polishing the interface for some API or other product I’ve been working on for a while. It just makes it feel more like a finished product. The final touch. The step moving away from jerryrig wires and oscilloscope probes to rugged connectors.
- bb88 3y agoCall me weird but I enjoy the LEMO connectors. I've used them for over a decade, and they just feel nice to plug in and remove.
- OldGuyInTheClub 3y agoNot weird at all! I've gotten lost in old LEMO catalogs many times.
- wildzzz 3y agoI've seen racks of CAMAC modules that all use LEMO. I rarely see them elsewhere. I've heard they are very popular in Europe.
- bb88 3y agoSo 3d maker pro is selling affordable 3d scanners with LEMO connectors on them. I've also seen them in military type gear.
- TOGoS 3y agoI will often spend hours researching different kinds of electrical connectors instead of....any other thing that I'm actually supposed to be doing. If I am feeling extra depressed I'll go order myself some Anderson PowerPole housings or maybe a kit of aviation connectors.
