By looking at the jumperless breadboard windows frame by frame before the window closes, it's throwing a "IndexError: Index out of range ... Failed to execute script 'JumperlessWokwiBridge' due to unhandled exception." So the software is just straight-up crashing due to a bug. Definitely just broken software; even if the user (Dave) was doing something "wrong", the software should be giving a guiding error message, not just crashing.

Please make a full episode on the Jumperless Breadboard! It’s so interesting I want to see it work

I mean the jumperless breadboard isn't all just so you don't have to plug in jumpers to be fair. If you set it up as a testing rig, you can just leave the chip or module in place, set up all your probes in different parts and write a program that can cycle them. Imagine plugging your mod-board or module or whatever in there and it runs through PSU, charging, pushes the buttons, checks serial, checks reverse polarity protection with a couple extra mosfets, you could do 90% of your product testing during prototyping in one of those things if it's not a precision product lol

An amazing amount of time was spent coming up with that design. A work of art. WOW

Whoever sent that first one in DEFINITELY knew how to catch Dave's attention.

Note that on the Sanwa pocket meter, the center "Off" position puts the thumb grip of the range switch fully within the case. Otherwise it extends beyond the edge, preventing you from closing it while it's still turned on. Nice attention to detail, and a good reason for having the Off position where it is.

After all these years, I'm still frustrated that Dave get toys in the mail and I still get bills! Maybe I'll get over this someday!😄

Your mailbags are the most bonkers assortment of items and by far my favorite!

That jumperless breadboard is amazing, I don't know what its niche is either. I think seeing the wires and where they go and moving them around a breadboard is an important part of learning electronics. My thought is if you have a bunch of projects that you might need again someday being able to store all the wiring to recall it later might be useful.

If the leds can be individually lid, they could make an automated build guide to assemble a schematic by highlighting the strip to place a component one by one for complete novices. A disadvantage of no jumper wires is that you can't tell what connects to what without a visualization of the netlist. It's over designed and over engineered to the point it's like an expenive fragrance. But could become a collectable.

Regarding the daughter board, it is easy to use regular LEDs. If you opt for bottom-emitting LEDs, most of them won't lay flat and require a hole in the PCB, so no text in the other side. And the LEDs that lay flat on the PCB and do not require a hole are quite expensive and not readily available.

The raspberry pi chip is just the brain for the bread board. You still need to add your own mc for a project.

Please do a full video with the Jumperless. I'd really like to see this thing in operation and learn more about what it can do.

The switch on the jumperless breadboard is labelled on the side of the building graphic, it switches the rail voltage between 8v 5v and 3.3v

noice! been a while since a mail bag! Solar powered Multimeter was used to build solar powered roadways!

This looks like an endless rabbit hole of weird and intristing things you could do! 🎉

Jumperless is a really cool project, nice to see it getting more attention

They probably used the little daughter board for the annunciator LEDs to provide more real estate on the main PCB for routing. All those little window cut-outs are taking up quite a bit of it right in the busy area of the Nano interface. I thought it was clever...

I was imagining a user-friendly interface for the jumperless breadboard. If you can just click 2 arbitrary points then the program just sorts out the wiring and uploads to the board, with the LEDs on the board indicating what has been connected, it would be a dream come true.

I got to know one of my recently graduated senior university student. Last year he worked as an internship student at Seagate (Teparuk, Thailand), even though his job was about (IIRC) production inspection. He also spend some time with the HGA (Head Gimbal Assembly) R&D team. After the internship period ended, he came back to Uni and told me a lot of stuff (of course, It's NDA-safe) about the Heat-assisted recording head. Like, how the recording head literally flying several nanometers above the disk platter in the helium wind (In the Data center grade HDD). Or the Heat-assisted recording laser use the near field wave guide (Near-field transducer peg) to focus the laser beam onto the platter. The HDD tech surely is the marvelous work of engineering!

Its seriously useful for synth enthusiasts. Would be nice to base a synth platform on this.

It's going to take some convincing for me with me with the jumper less bread board. I feel like every bug I get, I'd be worried about something going on wrong in the software or hardware layers of the bread board itself.

Jumperless is the coolest, most ingenious and most flexible tool for electronics that I have ever seen. The brand is an derivation of giant squid (Architeuthis dux)!

06:40 usb mini-b in 2024 is insane

Everyones favorite MAILBAG 10/10, best wishes Nick from the old dart

I've got to say that is one handsome looking breadboard... ngl when you turned it over and showed the ICs .. Dayum... you got this girl curious.

The jumperless breadboard may be "small" but you don't need a hole for each jumper pin; you can route the pin from a component directly to a pin on another component without needing to spend 2 extra holes. Also one use I see is that you can share layouts easily; just put the components on the board from instructions, "load the jumperwires" and you'e good to go.

This was my dream back in high-school

I used to use digital cross connect systems for telecommunications transport circuits and equipment. I love the idea that the idea has finally made it to the home gamer!!!

Something you didn't mention. The pocket multimeter. You can not close the case unless it's in the off position.

That breadboard is incredible! So impressive

Quite elegant to put the usb connecter in the corner at a 45° degrees angle so the cable gets out of the way...

An AmpHour show with a hard drive engineer would be awesome!

The drop shadow on your shirt makes it pop out really nicely. The 555 timer is my favourite chip. They're almost a solution in a chip. Most other chips are just one piece in a bigger project. Jumpers are really fun and aesthetic, but maybe jumperless would be fun also. I wonder if changing wiring on the fly can unlock dynamic wiring setups, or does it cut the power between wiring changes. I kind of already do dynamic wiring by just changing the jumpers around on the fly, so if it can't do that that would be a bit disappointing. Maybe changing the jumpers while the breadboard is powered up is kind of like cheating. So if there is no changing the jumperless wiring on the fly, it's preventing cheating. You're right about $200 being pretty steep for a jumperless breadboard. The only way I could justify the purchase would be to think of it as an investment for future projects like this to hopefully be cheaper and better later. Jumperless is a really cool idea. Often times I find it hard to figure out what intermediary steps there are between starting a project and it's completion, and I usually find that more intermediary steps help with debugging, and those extra steps actually make things faster for that reason. So maybe jumperless is another intermediary step between design, [jumperless], breadboard, solder, mass production. Maybe jumperless breadboards could also prevent short circuits and stuff like that.

You're always in focus...somewhere. What one of my TV broadcast teachers used to say.

The jumperless breadboard is likely good for schools that allow students to do labs remotely. It can be set up somewhere with many components and they can swap them in for different tasks.

I love little solar tools! (Like Mitutoyo's solar calipers...**chef's kiss**) I wish they had put a supercap in there rather than a battery. I mean isn't the whole point of a solar thingy that you can pull it out of a drawer 10 years from now and it just works? Casio did the same thing, switching their solar watches from supercap to battery.

Jumperless looks cool asf but I agree I don’t see how it saves any time.

This is such a cool project that I have been following! It actually did win 2nd Place in the Hackaday prize and the first place winner conceded that this project was way cooler than his! I think if you reach out the maker ... he seems to be fully invested in making this work for everyone that shows and interest! I am sure he will help you make it fun for you. This is truly a nerd art project. I hope you take a deeper look, get to playing with it and do another video when you figure it out! Once you see what it can possibly do. I thin the open source thing is what makes it awesome. The idea was born.. and its reaaly good and has amazing potential! Good stuff

That breadboard is amazing, but … I wouldn’t want to connect any circuit I built to a $300 device like that. It’s bad enough endangering the components I’m experimenting with!

I didnt know it was possible to have a jumperless breadboard. That's cool.

I'm definitely interested in the concept of a jumperless breadboard, i've been trying to get into electronics but have some dexterity issues/trembling issues and it makes bending / installing jumpers an absolute nightmare so something like this is a great idea for an accessibility market.

I think the solderless breadboard is great. A great use case could be disabled programmers who want to tinker with breadboard stuff.

RE: The headband thing. It'll work by galvanic vestibular stimulation. Essentially messing with the balance and orientation sensors in the inner ear. There has been some research into making VR headsets with this tech, to counter the 'stillness illness' effects of VR.

I would love to see more on first item thank you for all the great content I have been a fan for 8 years or so with a deferent account .

I love the design of the jumperless, but I can't imagine getting one. I have half-a-dozen projects on breadboards at any time and those generally have only a handful of jumpers. Still, super cool.

Thank you Dave for riding bike, thumbs up

jumper less can reconfigured on the fly this is universal, chip tester, eporm programmer, rom dumper, logic sniffer

Linus tech tips video about drive savers many years ago was fantastic. They repair and recover data from hard drives all day everyday. They might be good people to talk to about hard drives on the amp hour

This (jumperless), but on a Krone/110 style frame is something I have wanted to see :)

The reason for the "wishbone" PCB with the LEDs on the back of the Jumperless board is because they're addressable RGB WS2812-style LEDs, which AFAIK don't come in reverse-mount packages, especially in that super tiny package (having soldered them by hand a few times, I don't know if there's any way to make them that small and have room for both the leads and the actual light output).

That top header on the jumperless breadboard looks like the pinout for an Arduino Nano. Noice

3:21 It does. The label is literally next to it. 8V,5V,3.3V etc.. not the most clear label but it's there.

I once heard somebody refer the tech in hard disks as trying to fly a Boeing747 2mm of the ground. Off coarse I think these days they wouldn't use Boeing as a reference anymore :D

This thing needs some stand alone serial interface like the buspirate.

On the jumperless breadboard, there is text printed just right of the switch. Looks like it says RAIL, 8v, 5v and something else. It is hard to see it at first because the text is part of a larger object printed on the board that is also in white.

27:16 I wish people would say this more often. I went from 250lbs to 140lbs over the course of a few years, and yes, once you get past the first few days of feeling hungry, it becomes SO trivially easy. I wish people had told me this when I was younger instead of overcomplicating it with irrelevant diet and exercise advice. Devices like this seem primarily designed to demotivate you and trap you into feeling like losing weight is a gargantuan task that you'll never be able to achieve without unacceptable levels of pain and stress. They can only monetize you as long as you're fat, I guess, so why would they actually want you to lose weight?

30:30 Nice breadboard! You won't need to download a firmware for this one

My favorite segment! We need to send Dave more stuff!!

Hi Dave, I always enjoy your videos. I have a small suggestion: 28:20 It might be wise to avoid wearing unfamiliar devices on your head. There could be questionable intentions behind these items. It's always good to research wearables thoroughly and ensure they are safe before using them. Take care!

Your suggestion of using it to debug and test chips is *THE* 'killer app' for this!

I've thought about a jumperless breadboard before just using smd transistors. Just turning on a transistor to enable a jumper. Fairly simple just using a numeric keypad to enable the jumper.

Loved seeing the Lattice GDS reference...I cretaed the timing model in the datasheet back in the day.

Without the jumpers using up half the holes the breadboard is effectively twice the size. But yes. It is wonderful but overly complicated for what it does.

@3:20 The switch is a power switch I think. The voltages are written in the building icon.

That breadboard is fun for the first day, but all those extra steps just to connect a couple of things can get annoying. You need to power up your breadboard first and have an extra USB wire hanging on it, etc. Plus, it's not very clear where everything is connecting to if the room is bright, so you need to close the curtains, which means you need to stand up again. And there's the extra thing that can fail during testing and send you chasing a red herring, so now you need to debug your breadboard as well. 😋

Coolest breadboard I've ever seen. Ooh, SNAP, further in Nearly as cool as the Chrysler turbine was in 1960... I think the logo might mean "NO Jumping"

8:30 - This is the PROPER use of BLACK solder-mask; matte, not glossy!

The solder mask next to the switch on the solderless breadboard has "Rail", "8v", "5V", and "3.3V". Maybe there is an onboard converter that can change the rail voltage with the switch?

28:19 - Gee, I hope Modius selected a large enough BOX! WOW! I'll bet that manual is written in ~50 languages, ~2 pages/language!

I'm sold on the jumperless... because of automation...I couldn't bring myself to spend the money yet... but it's on my "to buy list"

That jumperless with the crossbar switches could be really cool if you wanted to build an analog computer but the 8 volt limit could be annoying

Wow! I need one to use with my Vion multimeter! 😂 BTW, did ya see those LEDs? That's definitely a Gamer Breadboard! Amazing ++!

I can’t get behind a jumperless breadboard. Purely out of pragmatism - my massive tub of cut-to-size breadboard wires would be e-waste! :p

7:13 The scattered parts around the "not jumping" logo is ... interesting? :D But at least unusual.

The ring lights on webcams are really designed for eye reflections.

OFF is in the middle on the Sanwa so the thumb lever doesn't protrude from the case. If the selector is in any other position, you can't close the cover, so you don't accidentally leave it on.

Reminds me when they were logic Probing the magic box in the Movie Sneakers 1992

It's fun watching Dave squirm, 'desperately' trying to be polite, since the breadboard guy has obviously gone to an enormous amount of effort and expense. So let's not hurt his feelings. But sheesh, it's like a $300 screwdriver, with LEDs and a learning curve. The 'solar roadway' equivalent for breadboards! I'm recalling the amazing 'breadboard computer' series that Ben Eater did. Now, imagine if Ben had used this device instead of vanilla breadboards for his build.

37:17 That mode selector is designed so the case will not close if the device is left on. That’s why OFF is in the middle.

Excellent for small scale testing and prototyping by the looks of it. Once you learn the coding it will probably be much quicker than manual jumper setups and definitely allows for more fast reconfiguration possibilities as well as potentially less capacitance/inductance/conduction issues with jumpers and high frequency rigs.

Jumperless breadboard would be ideal for field repairs on boards, especially when the manufacturers have obfuscated everything. Not pointing any fingers, *cough*Agilent*cough*, but a great right-to-repair tool in a compact form sounds amazing. No need for jumper wires and several tools like logic probe, 3/5/12v supply, diode tester etc, made redundant. Less tools to carry around in the field kit. Shame about the price

Look carefully at that logo for the jumperless breadboard. There are some voltages labeled. Maybe that switch is for voltage level selection

I think the LEDs are addressable, not sure whether there are bottom-emmiting addressable ones available, what price, so the daughterboard makes sense.

I think you're approaching the jumperless breadboard from the wrong direction. This is for people who develop and test their project in wokwi, then want an automated way to move it onto physical hardware. It's for people who are more comfortable with a GUI than with wires.

It can RICK ROLL! What other purpose do you miss???

Wow Dave. You need a bigger knife. My box opener fits in my pocket. That thing you got isn't going in your pocket. Lmao

I like how you can't close the DMM case without the meter being off. Don't have to worry about leaving it on and coming back to a dead battery.

I've had my PM3 for probably 6 years or more now, it's been through half a dozen batteries too and is pretty well worn but it's a great pocket meter.. I do like the look of that hard-cased one though.

299 $ no, for sure not ! Just an influencer product but I loved the screenshot of your version and youth flash back

What seems to be missing (in my opinion) for the jumperless breadboard is a printed quick-start guide pamphlet, which could include the info printed on the box. Yes, there are multiple sites and examples, but these tend to be overwhelming when you just want to see and test the basics.

That Jumperless could make for a useful HDMI port switcher. If my math is right it could host about 15 HDMI connections which would be useful for streamers.

33:35 Ben Eater would like a word! lol

I would love a breadboard that didn't have any gaps in the power rails.

Greetings from Austria. Your Antipode is greeting you.

the design of that Sanwa pocket meter is very neat, a design element i noticed is the reason for the central position of the off position on the range selector. it is so that thumb pad will stop the case closing if the meter is left on!

A nice little US$300 breadboard...

Geordi La Forge Jones... Great April fouls head gear.

I have been working in the embedded firmware field since the early 90's and it is very very rare PC software works the first time (if at all). I always have to load another python module, update .NET, manually copy paste dll's, etc. The quality of internal tools at companies is awful and on a regular basis simply reboots or throw's exceptions of all kinds. Digilent Waveforms is one exception, that code will run all weekend without any issues (if you make sure your PC doesn't deep sleep) but all the other vendor code will not run overnight without locking up (it's all .NET crap now). Years ago flicker was considered cheesy and now now one cares. Try to get a program to even remember your GUI settings after "a clean shutdown" is very rare. It's all a Lego's game now. Audio processing software has a higher standard so those developers are world class - because they have to be. If a company allows exceptions to be normal, management isn't doing their job. No wonder they want AI.
