#solderless — Public Fediverse posts

I'm looking for #opinions from #electronics #hobbyists or professionals.

When I'm using a #solderless #breadboard to prototype circuits, resistors can be frustrating. If you just keep re-using the same well-worn ones that look like a pretzel, you have to leave the leads long for the unknown next place you want to use them, and you can accidentally short something else against the leads.

Over the years I've frequently thought "Someone must make #jumper wires with inline resistors so they're easy to reuse", but I've never seen them for sale. [1]

So I made a bunch. And wow, it's labour-intensive to make them well. That explains why no-one's selling them.

Would other people be interested in buying and using these? Anyone can make them, but a lot of people would rather use their limited #hobby time to make their projects, not make things they need to make their #projects.

I've reduced the amount of time to make them and will keep trying, but I would have to charge at least US $30 for a pack of ten. There are ways to reduce it further, but they require a significant investment in equipment, so I'd have to be selling quite a few.

I make them with good materials - silicone 26AWG #wire for flexibility, name-brand 1% metal film #resistors, total length 24cm.

Would anyone want these?

[1] Closest thing I've found is https://www.dfrobot.com/product-1438.html but they're rigid so you need to use an additional wire anyway if you're not connecting exactly that distance through clear space.

Just a brief #factoid to perhaps save other #electronics #hobbyists some time.

#BigClive frequently uses a particular type of crimp-contact-and-housing as a universal socket for LEDs and other leaded components. Not just any such connector will do; various #JST, "#Dupont", and others won't work, because they only grasp pins of one particular size and/or shape. If the lead is too big, it won't go in, and if it's too small, it won't stay in.

If you want to use these connectors - and note you can get the housings with more than 2 contacts, so you can use them for transistors or weirder things too - the magic search term is "KF2510".

The reason these work as universal sockets for leaded components is because the contact is a spring that pushes from only one side of the housing, pressing the inserted contact or lead against the far side of the housing, and therefore provides a friction fit for any size lead (within reason). Most crimp connectors instead have particular shapes for their contacts and will only "grab" something the right size and shape.
