2025 One Hertz Challenge: A Discrete Component Divider Chain
Most of us know that a quartz clock uses a higher frequency crystal oscillator and a chain of divider circuits to generate a 1 Hz pulse train. It’s usual to …read more

The latest progress in the form of a test fitting and some gap filling underway. Still more to print, and SO MUCH painting to come. The interior includes three feet of 1/2"/13mm steel rod for structural support and weight.

Coleco Adam: A Commodore 64 Competitor, Almost
For a brief, buzzing moment in 1983, the Coleco Adam looked like it might out-64 the Commodore 64. Announced with lots of ambition, this 8-bit marvel promised a complete computing …read more

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.
