ARCHITEUTHIS FLUX — HENDERSON, NEVADA

Hey, I'm Kevin.

I make the Jumperless.

My name is Kevin Santo Cappuccio. I'm the entire "company" behind Architeuthis Flux LLC, a real registered business in Henderson, Nevada that designs, hand-tests, packs, and ships a piece of weird open-source hardware called the Jumperless. There is no team. There is no warehouse in some other country. There is no drop-ship middleman. There is me, a soldering iron, a pile of PCBs, a dog named Quark, and an obsessive need to make prototyping electronics less of a tangled-jumper-wire nightmare.

If you order something from this store, I am personally the person who reads that order, prints the label, packs the box, and walks it to UPS. If something breaks, you email me directly and I fix it for free, forever.
That's not marketing copy, it's just how this works because there's nobody else here to tell me that's a bad idea.

So what is this thing?

Jumperless V5 lets you prototype like a nerdy wizard who can see electricity and conjure jumpers with a magic wand. It's an Integrated Development Environment (IDE) for hardware — an RP2350B-based dev board, a drawer full of wires, and a workbench full of test equipment (power supply, multimeter, oscilloscope, function generator, logic analyzer) all crammed inside a breadboard.

You can connect any point to any other using software-defined jumpers. RGB LEDs under every hole turn the breadboard itself into a display showing what's happening in your circuit in real time. It's not about being too lazy to plug in jumper wires (although yes); the circuit itself becomes scriptable, which opens up a bunch of crazy stuff you can't do on a regular breadboard.

Or, you know, you can just play Doom on it. So yeah, wizard shit.

Who actually runs this store?

Me. Kevin Santo Cappuccio. I'm the sole proprietor and operator of Architeuthis Flux LLC, a Nevada-registered LLC. The legal business address is 3493 Brezine Avenue, Henderson, NV 89044, United States. That's also where the Jumperlesses get packed and shipped from. You can reach me at kevin@jumperless.org or (408) 315-9511. I will probably answer.

Where is the hardware made?

PCBs are fabricated and assembled at my ride-or-die contract manufacturer I've used since 2022, Elecrow. The 3D-printed breadboard shells are SLS PA-12 nylon from JLC3DP. The custom phosphor-bronze spring clips are made by Shenzhen Fulimei. Boxes are made by Zhibang Packaging.

Each Jumperless gets powered up and run through its startup calibration before it goes in a box, which then gets lovingly wrapped, spray painted, and glittered by me in Henderson, Nevada.

Is the hardware really open-source?

Yes, all of it. Hardware design files are licensed under the CERN Open Hardware License v2 (Weakly Reciprocal). Firmware and desktop app are MIT-licensed. KiCad project files, schematics, BOM, gerbers, and firmware are all on GitHub. If you want to make your own, go for it — I'll even help you order PCBs.

What happens if it breaks?

I fix it or replace it. For free. Forever. There is no warranty period — I call it the Infinite Warranty because that's literally how it works. If you misplace your probe, blow a crossbar switch, let your dog chew on it, or just don't enjoy it, email me at kevin@jumperless.org and I'll get you sorted out with a fresh one, parts to repair it yourself, or a full refund. Your choice.

What's the return policy, in plain English?

You have Unlimited days from receiving your order to request a return for any reason. EU/UK customers have the standard 14-day cooling-off right, plus my unlimited-day policy on top. Refunds are issued by your original payment method within 5 business days of receiving the return. I cover the return shipping label. Email kevin@jumperless.org to start a return.

How does shipping work?

US orders ship via UPS Ground or 2nd Day Air (1–4 business days typical). International orders ship via UPS Worldwide (3–10 business days typical). Tracking is emailed automatically. International customers are responsible for any customs duties or VAT charged by their country — I declare the full purchase value on the customs form as required by law. **wink emoji**
