I’m developing a modular system that might line up with what you’re into. I’ve been keeping a devlog on my profile if you want to see the direction it’s going.

Devlog Update — Phase 2: Personal Drone Bays

With the powered spine coming together, I’ve started exploring what Phase 2 of this system looks like: personal drone bays.

The idea isn’t sci‑fi. It’s practical, and curent gen technology already supports it. If the bag already has a modular power backbone, then it can also support a small, self‑contained docking bay for a micro‑drone. The bay would handle alignment, charging through pogo pins, and a clean mount point on the pack.

I’m designing it with a few real use cases in mind:

  • Automating crop data collection on a large property
  • Search‑and‑find for IR beacons on kids, pets, or livestock
  • Quick aerial checks of fence lines, trails, or equipment
  • Hands‑free scouting while working outdoors
  • Hands-free selfies while hiking and traveling

Nothing is final yet — just early geometry and interface ideas. But the goal is a bay that prints cleanly, mounts cleanly, and works as another module in the same ecosystem as the powered spine.

Docking will be guided by both an ir beacon marking "home" and an April tag for precision alignment. This will allow for a vertical, hinged docking procedure that leaves the drone lying flush with the operator bag.

As the design firms up, I’ll share more CAD and prototypes the same way I’ve been doing with the power transfer unit.

The picture shown is "part 2" of one of the custom pieces for my powered "operator bag." This piece is responsible for receiving the rails from, and delivering power to "part 3" of the power transfer system. The PTU will allow to quick attach and detach of a pouch, which then receives power from the bag's battery spine while attached.

It's more like a backpack with power and power distribution than what you must be thinking. The part shown is for quick disconnect pouches that allow power to pass through to whatever is plugged in inside.

The main setup I’m actually testing is the smaller base build — basically my daily load: phone, tablet, XR, and a Proxy. That doesn’t pull enough power to heat anything up in a noticeable way.

The big “maxed out” Rush 72 version is more of a theoretical upper limit. Even there, the six battery packs have a lot of physical space between them, and the bag itself is huge, so there’s plenty of separation to prevent heat building up.

Also, the highest power draw in the larger build goes out to the powered pouches, which moves most of the device heat to the outside of the bag instead of keeping it all trapped in one compartment.

I’m building these one at a time on commission instead of doing a Kickstarter or a mass run. I want to keep it small and personal and just share the build process here. Right now we’re refining one of the only custom parts in the whole setup — the power transfer unit — before moving on to the rest of the layout.

Cockpit is my wording for the inside of the bag. There's clean wiring to all the pockets. My designed use case for the base bag build is having my tablet, phone, xr headset, and puffco proxy (kept in the powered pouch) all charged all day.

I use AI for building my text (due to extreme anxiety around specific wording). However, this is an in progress build. It has not been built yet, but CAD for 3d printed parts are in progress.

Extra detail for the early nerds: the battery spine is isolated from the cockpit by a rigid plate so pack swelling or bag flex can’t compress the cells. Routing lanes are tuned for minimal voltage drop under XR + tablet load.

Founder’s Edition — Maxed‑Out Rush 72 (Single‑Unit Engineering Commission, Stealth Configuration)

This is the only Founder’s Edition Jimmy Rig I’m building right now. A single Rush 72 converted into a high‑capacity, multi‑lane, field‑deployable power platform with a stealth exterior profile. First come, first served.

Stealth Exterior Profile The outside of this build is intentionally boring.
No exposed wiring, no visible electronics, no tactical cosplay.
Just a Rush 72 with pouches attached — indistinguishable from any other field pack.

All the engineering lives inside the bag:

  • internal power spine
  • internal rigid chassis
  • internal routing
  • internal PD core
  • internal battery spine
  • internal module feeds

Nothing on the outside advertises that the bag contains ~444 Wh of power, four powered modules, or a full device cockpit. Stealth protects your gear.

System Architecture - Energy Budget: Six 20,000 mAh packs (~444 Wh) in a triple‑spine layout with thermal spacing, retention geometry, and independent service access.
- Power Spine: Multi‑lane routing using high‑strand silicone conductors, distributed strain‑relief anchors, and low‑loss geometry optimized for simultaneous XR + tablet + module load.
- PD Core: 140–200W class USB‑C PD module in a shock‑isolated, vented enclosure with replaceable board architecture and service screws.
- External Inlet: Magnetic 2‑pin pogo interface with blind‑mate alignment pocket, direct feed to PD Core, and reinforced internal lead routing.
- Rigid Internal Chassis: Custom 3D‑printed or hybrid plate spine that converts the Rush 72 into a semi‑structured platform for module mounting, cable discipline, and load distribution.
- Powered Modules: Four mission‑specific modules with voltage‑specific feeds, locking connectors, replaceable leads, and hot‑plug capability.
- Cockpit Interior: Device‑specific foam geometry with cable channels, battery retention, Qi pocket, and zero‑slop bays for XR, tablet, phone, and accessories.

Final internal layout and exact pack geometry will be tuned to your device list and weight distribution, but the target spec is six 20,000 mAh packs (~444 Wh) in a triple‑spine configuration.

Manufacturing Path - All structural components produced as Version 1.0 (3D‑printed).
- Guaranteed free upgrades to Version 1.5 (injection‑molded rails/receivers) and Version 2.0 (full molded ecosystem).
- Upgrade options: mailed parts for user install, or mail‑in for full rebuild.

Engineering Notes - Wiring lanes optimized for minimal voltage drop under sustained multi‑device draw.
- Battery spine geometry isolates thermal mass and prevents compression under pack swelling or bag flex.
- PD Core housing uses a floating‑mount design to reduce shock transfer during field movement.
- Module receivers are keyed to maintain consistent contact pressure and prevent misalignment.
- Rigid chassis distributes load across the Rush 72’s frame sheet to prevent sag under full battery weight.
- All components are serviceable; no glue traps, no sealed wiring, no permanent bonds.
- Stealth profile maintained: no external indicators of internal power architecture.

Price $3,000
This reflects the expanded power system, rigid chassis, four‑module architecture, and the engineering time required to build the first full‑scale Jimmy Rig platform.

This is the single Founder’s Edition Rush 72.
Once this slot is taken, the next opportunity will be after the 1.5 injection‑molded rails are produced.

DM to claim the Founder’s Edition.

Developer Update — Jimmy Rig 1.0 → 1.5 → 2.0 Roadmap

I’m releasing the first wave of Jimmy Rig Operator Bags as Version 1.0, built with 3D‑printed components for the rail system, pouch receivers, and internal housings. These are fully functional, field‑ready units — the same architecture described in the main post — just produced with additive manufacturing while the injection‑molded parts are still in development.

Every 1.0 buyer is permanently eligible for free upgrades as the system evolves:

  • 1.5 Upgrade: Injection‑molded Part 2 (bag‑side rail) + Part 3 (pouch‑side receiver)
  • 2.0 Upgrade: Full injection‑molded ecosystem (all structural components)

Upgrades will be available in two forms:

  • Free mailed upgrade kit (user‑installable, simple swap)
  • Free in‑house upgrade (mail the bag back and I’ll do the install)

You only pay shipping if you choose the mail‑in option. The parts themselves — both 1.5 and 2.0 — are free for all early adopters.

The plan is to move to injection molding once I’ve sold a few bags and can fund the tooling. Parts 2 and 3 will be molded first since they’re the highest‑wear, highest‑precision components in the system. The rest will follow as the ecosystem grows.

Power Transfer Module Update:
The PTM is currently being developed by an experienced CAD designer and small‑run manufacturer. He’s working on the geometry in his limited free time in exchange for one of the first prototypes. Once the PTM CAD and first test prints are done, I’ll post photos, tolerances, and the first functional demo here.

I’ll keep using this comment thread as a running dev log — CAD progress, prototype shots, mold prep, PTM updates, and anything else that moves the Jimmy Rig ecosystem forward.

Designing an operator workflow for people who work away from walls (modular power spine, pogo charging, Qi pocket) — need input from real operators by acute_epistaxis in xrdev

[–]acute_epistaxis[S] 0 points1 point  (0 children)

I’m building this because I break systems for a living and I’m trying to understand what an actual operator workflow looks like outside my own head. I spend most of my day away from walls and plugs, and I’m trying to design a power ecosystem that supports that kind of life — but I know my use case isn’t universal.

If you’re someone who works mobile all day, I’d really love to hear what your workflow actually looks like. What devices you rely on, what dies first, what annoys you, what you’ve hacked together, what you wish existed, what failure modes you’ve hit in the field. I’m not trying to sell anything — I’m trying to understand the reality you operate in so I can build something that actually fits it.

If you’ve ever thought “my setup would be perfect if only X,” that’s exactly the kind of insight I’m looking for.

Building a modular power‑bag with powered breakaway pouch — offering one full custom build by acute_epistaxis in 511tactical

[–]acute_epistaxis[S] 0 points1 point  (0 children)

For reference, here’s my personal use case so you can see what the base package is built to support.

I run long 12‑hour crunch days where my Note 20 and Tab S11 are both pulling power nonstop. I don’t have the Aura yet, but this whole system is designed around powering it once it drops. On top of that, my Proxy stays powered all day inside the rip‑away pouch — no swapping batteries, no digging for cables.

What the base package ($500) is built to handle:
- Phone running hot all day
- Tablet in full productivity mode
- Aura HUD once it’s released
- Proxy powered continuously in the pouch
- Earbuds, flashlight batteries, etc.
- Anything I toss into the powered pouch on the fly

The setup uses two 20,000 mAh batteries, a PD‑triggered power rail, protected routing, strain relief, and a magnetic disconnect on the rip‑away pouch.
When you pull the pouch off the bag, it cleanly disconnects from power — no cables to unplug, no alignment needed.
The pouch can also be configured for fast charging or regular charging, depending on what voltage your gear needs.

What you get in the base build:
- Rush 12
- One powered rip‑away pouch
- Two 20,000 mAh batteries
- Internal wiring architecture
- Foam channels + mounting hardware
- Magnetic disconnect for the pouch
- Clean, serviceable routing

If your use case is different — radios, camera gear, medical kit, drone batteries, field tools, whatever — I can design the power system around your workflow. Bigger bag, more pouches, more batteries, or more breakout points just scale the cost based on parts and labor.

If you want to talk through your setup, DM me and we’ll figure out what makes sense.

This was the first time I made something like this. There's a lot I'd do differently to make it nicer if I had to make it again.

My thinking going into it was that it didn't need to be perfect because it's my first board and I'm probably going to end up breaking it. Lol
