Fantastic. Any plans of selling these?

Yep, they're up on my Tindie store here: www.tindie.com/products/architeuthisflux/jumperless/

75 ohm resistance is too much between a connection

@arabidsquid Жыл бұрын

For certain things it may be, but for most normal, high resistance circuits you'd build on a breadboard it seems to be pretty negligible, especially because they're all the same 75 ohms. It is a thing to be aware of though. And I'm limited to crosspoint switches that actually exist (even if cost was no object, they don't make analog crosspoint switches with lower on resistance that can handle anything more than like 2.5V.) But yeah, one day when I can make my own custom silicon for this, I'll make a beefier crosspoint switch better suited to this application.

@@arabidsquidI even thought about parallelizing the chips together so that the current increases and the resistance decreases, but I realized that, ideally, we should not have more than several or just 1 Ohm resistors. This issue practically rules out using current chips; it is not feasible. Creating your own chip is a very intriguing idea. You might want to look into FPAA (Field-Programmable Analog Arrays). These chips are similar to FPGA but are designed for synthesizing analog circuits.

Having a schematic automatically mapped to a breadboard would be easier I think.

You totally could, but then you'd have to worry about adding footprints and pinouts for everything on the board so the software know what goes where. But in this particular case, I didn't have that information. I might be able to make that work as a copy/paste thing from a KiCad schematic, but probably not anytime soon.

What is this voodoo magic?

@arabidsquid Жыл бұрын

The real magic is inside the analog crosspoint switches. But if you want to read more about this thing, it's on Github here: github.com/Architeuthis-Flux/Jumperless
