Wiring a Counter Circuit in Under

Here I'm wiring a 74HC191 up/down counter with a 555 clock source in just under 2 and a half minutes using a Jumperless.
This is just to show off the latest features I added to probing mode. Namely, when you probe out a row that's physically connected something else on the breadboard, it lets you cycle through them to pick which one you meant to connect. It also lets you choose whether to use the 3.3V or the 5V power supply.
The new Jumperless firmware (1.3.7) can scan the board really quickly (~100 times per second) to look for the PWM signal coming from the probe. So now you can just poke out the connections you want to make and the Jumperless will make them into real hardware connections. No computer required.

I can't *believe* how few views this has. This is the kind of thing hardware tinkerers *dream* of. Cool enough that you could use a breadboard-like interface without wires, but now to be able to probe out digital wires? It's the best of the physical wiring without the fiddliness of actually wiring (especially when it comes to more complex setups like this where wires get in the way of each other)! Granted, building one is more expensive than a breadboard + wires, it's still amazing and would be super handy! Great job, seriously!

That's insane. This is a new development? (I had no idea you could just probe connections into being instead of having to program connections via a computer). In my opinion, this is genuinely the most useful thing for DIY/maker/hobby electronics (and obviously useful for "professional" situations too) in a long time. Even the earlier firmware that required a computer is something that would make prototyping much faster and easier. Creating the ability to add connections via simply probing points on the board has made this even more of a must-have tool for me - I was going to leave it a while before getting myself one, but now that I've seen this, I'll be ordering one soon. Honestly, given how much I use GPT-4 when making things, I think there's a lot of potential in developing a program that would use the features of OpenAI's API or custom GPTs (both can be customized/given specifics/restricted much more than standard GPT-4) to allow the AI assistant to view stats from your Jumperless in order to provide component recommendations, troubleshooting advice, etc.

It’s been a ridiculous week of development adding new features. I started legit semantic versioning when I made the app automatically flash the latest firmware release at 1.3.0 7 days ago and this is 1.3.7 I just pushed today. So yeah, the probing thing is a week old and it’s hella useful. There’s also the a standalone app, Jumperlab, made by a total rockstar who bought one a while ago where we’re doing more advanced stuff like controlling it over a webcam feed and basic oscilloscope/logic analyzer/function generator/component tester shit. github.com/nilclass/jumperlab

if you have one of these: do not let anyone borrow it. (my own personal experience with breadboard-sockets is that people tend to shove components into it that have leads too big for the holes ... and then they wonder why it stopped working)

Yes, that is an issue with cheap breadboards. But for this, I had to get breadboard spring clips custom manufactured so they have tabs to solder onto a PCB and holes for the LEDs. So I had them made of Phosphor Bronze which is more expensive but is amazingly springy and won’t deform from putting too big of leads into them. I sell the clips by themselves so people can make their own cool things with breadboards too. www.tindie.com/products/architeuthisflux/solderable-breadboard-spring-clips/
