# RemoteRig — Camera Node Hardware Design
|
||
|
||
> **Version:** 0.3.0 | **Status:** v4 CAD prototype ready for measurement/print validation
|
||
> **Target:** GoPro Hero 3 Black/Silver + ESP32-C3 Super Mini + ESP-01S + USB power bank
|
||
|
||
## Overview
|
||
|
||
Each camera node is two ESP boards in a small upright stand-mounted case. The case **does not attach to the camera**; it straps to a tripod/lighting stand with reusable cloth zip ties / Velcro straps. Powered by a standard USB power bank.

## Bill of Materials
|
||
|
||
| Item | Qty | Cost | Notes |
|
||
|------|-----|------|-------|
|
||
| ESP32-C3 Super Mini | 1 | ~$4–$6 | MQTT / hub-side bridge; known board envelope 22.5 × 18 mm |
|
||
| ESP-01S / ESP8266 module | 1 | ~$2–$3 | Camera-side GoPro Wi-Fi bridge; known envelope ~24.7 × 14.3 × 12 mm |
|
||
| 1.3-inch OLED/status screen | 1 | ~$4–$8 | Prototype CAD assumes ~31 × 16 mm visible window / ~37 × 22 mm panel recess; confirm exact module |
|
||
| 3 mm power LED | 1 | <$1 | Separate always-power/5V indicator |
|
||
| 3 mm RGB status LED | 1 | <$1 | Replaces separate red/green status LEDs; firmware can map node states to color |
|
||
| Small rocker switch | 1 | ~$1–$3 | On/off switch; prototype CAD assumes 13 × 19 mm snap-in opening |
|
||
| USB power bank (5000 mAh+) | 1 | ~$10 | Powers camera node and GoPro |
|
||
| Short USB cables / wiring | as needed | ~$2–$5 | Power bank → node + GoPro; internal power/signal wiring |
|
||
| M2 or small self-tapping screws | 4 | <$1 | Front service lid screws; pilot holes are parametric |
|
||
| PETG filament | ~35–50 g | ~$1 | 3D printed case body + lid |
|
||
| Reusable cloth zip ties / Velcro straps | 2 | ~$1 | Primary stand mount through rear strap channels |
|
||
|
||
**Total per node:** roughly ~$25–$35 plus GoPro and power bank, depending on display/switch choice.
|
||
|
||
## 3D Printed Case
|
||
|
||
**Current source:** `hardware/case/camera-node-case-v4.scad`
|
||
**Pipeline:** `hardware/DESIGN_PIPELINE.md`
|
||
|
||
The current v4 CAD replaces the rejected wide/low electronics-box layout with a tall appliance-style enclosure matching the original upright reference: a clean vertical body, large inset front panel, OLED near the top, open blank middle area, two long rounded lower slots, and a bottom-center cable exit. It also replaces the v3 clamp/dovetail concept with a simpler strap-mounted field enclosure:
|
||
|
||
1. **Case body** — shell sized around ESP32-C3 Super Mini + ESP-01S with service/wiring clearance.
|
||
2. **Flush/recessed full-height front service lid** — screw-on front panel with locating lip and a restrained raised/recessed border.
|
||
3. **Front panel controls/indicators**:
|
||
- 1.3-inch OLED/status screen window.
|
||
- 3 mm **PWR** LED.
|
||
- single 3 mm **RGB STAT** LED for state-dependent colors.
|
||
- small rectangular rocker switch cutout.
|
||
- two long rounded lower front slots styled after the reference appliance face.
|
||
4. **Rear strap channels** — two low-profile external belt-loop cloth zip-tie / Velcro strap paths to reduce rotation on a tripod/stand without visually dominating the body.
|
||
5. **Bottom cable exit** — cable/strain-relief notch for USB/power wiring.
|
||
|
||
### Export wrappers
|
||
|
||
Simple per-part OpenSCAD wrappers are included:
|
||
|
||
- `hardware/case/camera-node-case-v4-body.scad`
|
||
- `hardware/case/camera-node-case-v4-lid.scad`
|
||
- `hardware/case/camera-node-case-v4-preview.scad`
|
||
|
||
Example CLI exports, if OpenSCAD is installed:
|
||
|
||
```bash
|
||
openscad -o hardware/case/camera-node-case-v4-body.stl hardware/case/camera-node-case-v4-body.scad
|
||
openscad -o hardware/case/camera-node-case-v4-lid.stl hardware/case/camera-node-case-v4-lid.scad
|
||
openscad -o hardware/case/camera-node-case-v4-preview.stl hardware/case/camera-node-case-v4-preview.scad
|
||
```
|
||
|
||
Or render the main file directly:
|
||
|
||
```bash
|
||
openscad -D 'part="body"' -o hardware/case/camera-node-case-v4-body.stl hardware/case/camera-node-case-v4.scad
|
||
openscad -D 'part="lid"' -o hardware/case/camera-node-case-v4-lid.stl hardware/case/camera-node-case-v4.scad
|
||
openscad -D 'part="preview"' -o hardware/case/camera-node-case-v4-preview.stl hardware/case/camera-node-case-v4.scad
|
||
```
|
||
|
||
### Print Settings
|
||
|
||
- **Material:** PETG preferred for heat/outdoor use and strap-tab durability.
|
||
- **Layer:** 0.2 mm typical.
|
||
- **Infill:** 20% gyroid minimum; 30%+ recommended around rear strap bridges.
|
||
- **Supports:** likely minimal/none depending on orientation; verify rear strap bridge spans and cable notch in slicer.
|
||
- **Post-processing:** fit 4 lid screws; deburr OLED/LED/switch cutouts; soften strap-channel edges if the printed radius is too sharp for cloth ties.
|
||
|
||
## Expected Status Screen Content
|
||
|
||
Preferred 1.3-inch OLED layout/content style:
|
||
|
||
```text
|
||
CAM 03 REC ●
|
||
BAT 87% LINK OK
|
||
00:12:34
|
||
```
|
||
|
||
Suggested fields:
|
||
|
||
- `CAM` / node ID.
|
||
- `REC` state with a clear recording indicator.
|
||
- Battery percentage or supply estimate.
|
||
- `LINK OK` / degraded / disconnected state.
|
||
- Recording/session timer.
|
||
|
||
## Wiring
|
||
|
||
```text
|
||
USB Power Bank
|
||
├── USB-A → Camera Node Case
|
||
│ ├── rocker switch → node power rail
|
||
│ ├── PWR LED indicator
|
||
│ ├── ESP32-C3 Super Mini
|
||
│ ├── ESP-01S / ESP8266
|
||
│ ├── 1.3-inch OLED display
|
||
│ └── RGB status LED
|
||
│
|
||
└── USB-A → GoPro USB port
|
||
(power only — no data)
|
||
|
||
UART / control inside case:
|
||
ESP-01S TX ──→ ESP32-C3 RX
|
||
ESP-01S RX ←── ESP32-C3 TX
|
||
ESP-01S GND ─── ESP32-C3 GND
|
||
```
|
||
|
||
**Power note:** exact wiring depends on the regulator/power board used. Confirm OLED voltage, LED current limiting, and whether the rocker switches USB 5 V input or a regulated node rail.
|
||
|
||
## Wi-Fi Topology
|
||
|
||
```text
|
||
GoPro Hero 3 ──(AP @ 10.5.5.1)──→ ESP-01S / ESP8266 camera bridge
|
||
│
|
||
UART │ (inside case)
|
||
│
|
||
Travel Router ──(AP)────────────────────→ ESP32-C3 MQTT bridge
|
||
(10.60.1.1) │
|
||
│
|
||
MQTT │
|
||
▼
|
||
Pi Hub (10.60.1.56)
|
||
```
|
||
|
||
The ESP8266/ESP-01S and GoPro talk over Wi-Fi. The only cable to the GoPro is USB power from the battery pack.
|
||
|
||
## Field Setup
|
||
|
||
1. Mount GoPro on tripod/stand.
|
||
2. Route two reusable cloth zip ties / Velcro straps through the rear v4 case channels.
|
||
3. Strap the case to a tripod/stand leg; use both strap paths to resist rotation.
|
||
4. Connect power bank to case and GoPro.
|
||
5. Toggle rocker switch on.
|
||
6. Verify PWR LED, RGB status LED, and OLED status: camera ID, REC state, battery, link, timer.
|
||
7. Monitor from `http://10.60.1.56:8080`.
|
||
|
||
## Case Dimensions
|
||
|
||
Prototype v4 nominal CAD dimensions:
|
||
|
||
| Part / feature | W × D × H (mm) |
|
||
|---|---|
|
||
| Case shell external | ~56 × 36 × 82 |
|
||
| Case with rear strap bridges | ~56 × 40 × 82 |
|
||
| Front recessed lid | visible panel ~48 × 2 × 74; total with locating lip ~48 × 3 × 74 |
|
||
| OLED visible window assumption | ~31 × 16 |
|
||
| Rocker cutout assumption | ~13 × 19 |
|
||
| Rear strap channels | two low-profile external belt-loop paths, ~33 mm usable slot width, ~4.2 mm strap-thickness clearance |
|
||
| Board clearance targets | ESP32-C3 22.5 × 18 mm + ESP-01S 24.7 × 14.3 × 12 mm plus wiring/service clearance |
|
||
|
||
These dimensions are placeholders for the first CAD prototype. Measure the actual OLED module, rocker switch, LEDs, screws, USB cable bend radius, and strap width/thickness before committing to production prints.
