# RemoteRig Hardware Design Pipeline
|
||
|
||
> Living queue for 3D-printed / physical hardware design work.
|
||
|
||
## Active / Ready for CAD prototype
|
||
|
||
### Camera node case v4 — status panel + strap mount
|
||
|
||
**Status:** Parametric OpenSCAD source created; body/lid/preview STLs exported and validated watertight. Ready for CAD review, exact part measurement, and first prototype print.
|
||
|
||
**Files:**
|
||
|
||
- `hardware/case/camera-node-case-v4.scad`
|
||
- `hardware/case/camera-node-case-v4-body.scad`
|
||
- `hardware/case/camera-node-case-v4-lid.scad`
|
||
- `hardware/case/camera-node-case-v4-preview.scad`
|
||
- `hardware/case/camera-node-case-v4-body.stl`
|
||
- `hardware/case/camera-node-case-v4-lid.stl`
|
||
- `hardware/case/camera-node-case-v4-preview.stl`
|
||
|
||
**Design direction:**
|
||
|
||
- Stand-mounted camera node enclosure; the case still does **not** mount to the GoPro.
|
||
- Primary mounting is now reusable cloth zip ties / Velcro straps through rear case channels, not a clamp/dovetail.
|
||
- Front has a recessed/flush service lid similar to a field-service status panel.
|
||
- Lid includes cutouts for:
|
||
- 1.3-inch OLED/status screen.
|
||
- separate 3 mm power LED.
|
||
- single 3 mm RGB status LED replacing red/green status LEDs.
|
||
- small rocker on/off switch.
|
||
- lower vent/style slots.
|
||
- Body includes screw bosses, recessed lid pocket, lid locating geometry, bottom cable exit/strain-relief notch, and two rear horizontal strap channels to resist rotation on a stand.
|
||
- Internal envelope is sized for known module dimensions plus service clearance:
|
||
- ESP32-C3 Super Mini: 22.5 × 18 mm.
|
||
- ESP-01S: ~24.7 × 14.3 × 12 mm.

|
||
|
||
**Prototype dimensions to validate before production:**
|
||
|
||
- Exact 1.3-inch OLED module dimensions:
|
||
- PCB width/height/thickness.
|
||
- active display/window width/height.
|
||
- connector side and ribbon/header clearance.
|
||
- mounting-hole positions, if using module screws or adhesive tape.
|
||
- Rocker switch:
|
||
- snap-in cutout width/height.
|
||
- bezel/flange size.
|
||
- required panel thickness range.
|
||
- rear depth and terminal clearance.
|
||
- LEDs:
|
||
- preferred holder/bezel style, if any.
|
||
- final hole diameter for 3 mm PWR LED and 3 mm RGB STAT LED.
|
||
- current-limiting resistor placement.
|
||
- Wiring/service:
|
||
- USB cable diameter and bend radius.
|
||
- whether power enters through bottom notch, side notch, or panel connector.
|
||
- actual regulator/power distribution board footprint if used.
|
||
- Fasteners:
|
||
- M2 vs M2.5 vs self-tapping screws for lid.
|
||
- pilot diameter, screw length, and head/counterbore diameter.
|
||
- Mounting straps:
|
||
- cloth zip-tie / Velcro width and thickness.
|
||
- whether two strap paths are enough to prevent case rotation on the expected stand diameter.
|
||
- whether rear bridge edges need larger radii or TPU/silicone sleeve protection.
|
||
- Printability:
|
||
- rear strap bridge bridging/support behavior.
|
||
- body/lid fit after PETG shrinkage.
|
||
- lid lip clearance and screw boss robustness.
|
||
- cable notch strength and strain relief.
|
||
|
||
**Suggested OpenSCAD validation/export commands:**
|
||
|
||
```bash
|
||
openscad -o /tmp/camera-node-case-v4-body.stl hardware/case/camera-node-case-v4-body.scad
|
||
openscad -o /tmp/camera-node-case-v4-lid.stl hardware/case/camera-node-case-v4-lid.scad
|
||
openscad -o /tmp/camera-node-case-v4-preview.stl hardware/case/camera-node-case-v4-preview.scad
|
||
```
|
||
|
||
Latest validation: OpenSCAD reports `Simple: yes`; trimesh confirms body, lid, and preview STLs are watertight. Body and lid each export as a single connected printable component; preview includes separate non-print board guide volumes by design.
|
||
|
||
Or with the main parametric selector:
|
||
|
||
```bash
|
||
openscad -D 'part="body"' -o /tmp/camera-node-case-v4-body.stl hardware/case/camera-node-case-v4.scad
|
||
openscad -D 'part="lid"' -o /tmp/camera-node-case-v4-lid.stl hardware/case/camera-node-case-v4.scad
|
||
openscad -D 'part="preview"' -o /tmp/camera-node-case-v4-preview.stl hardware/case/camera-node-case-v4.scad
|
||
```
|
||
|
||
## Prior prototype reference
|
||
|
||
### Tripod electronics case v3
|
||
|
||
**Status:** Historical design reference. In this checkout, previous v3 SCAD/STL files are not present; v4 starts a new `hardware/case/` CAD source set.
|
||
|
||
**Previous design notes:**
|
||
|
||
- Held ESP32 + ESP8266 stack.
|
||
- Screw-on lid with vent slots.
|
||
- Rear dovetail-style rail/socket interface.
|
||
- Separate screw-tightened tripod clamp sized around a 35 mm stand/pole.
|
||
- Clamp used M3 hardware: one M3 screw across the clamp mouth, with an M3 nut trap.
|
||
|
||
**Reasons superseded by v4:**
|
||
|
||
- User requested front status/service panel with OLED, LEDs, and rocker switch.
|
||
- Single RGB status LED replaces separate red/green status LEDs.
|
||
- Strap channels are simpler and more adaptable than a dedicated clamp/dovetail for field stands.

## Backlog

### 10.1-inch touchscreen + Raspberry Pi Zero case
|
||
|
||
**Status:** Specific display identified; mechanical measurements needed before CAD.
|
||
|
||
**Goal:** A printable enclosure for the RemoteRig hub/control panel using a 10.1-inch touchscreen and Raspberry Pi Zero / Zero 2 W.
|
||
|
||
**Display target:**
|
||
|
||
- Vendor/model: HZWDONE Raspberry Pi Screen 10.1" Touchscreen
|
||
- Resolution: 1024×600
|
||
- Interface: HDMI portable monitor
|
||
- Mounting: includes fixing holes
|
||
- Compatibility listing: Raspberry Pi 5/4/3B/B+ and Windows 11/10/8
|
||
|
||
**Initial assumptions to validate:**
|
||
|
||
- Compute: Raspberry Pi Zero / Zero 2 W mounted behind or below the display.
|
||
- Use case: RemoteRig local monitor/control panel at field recording setup.
|
||
- Likely needs: front bezel, rear electronics cavity, Pi mounting posts, HDMI/USB/power cable exits, strain relief, ventilation, and optional tripod/stand mounting.
|
||
- Because this is a 10.1" panel, design should prioritize rigidity: thicker bezel ribs, rear standoffs, and possibly a two-piece shell instead of a small snap case.
|
||
|
||
**Required measurements before CAD:**
|
||
|
||
- Product link or datasheet for the exact HZWDONE 10.1" variant.
|
||
- Screen/PCB outer dimensions: width, height, thickness.
|
||
- Active display opening dimensions.
|
||
- Fixing-hole locations, hole diameter, and screw size.
|
||
- Connector locations/orientation for HDMI, USB touch, and power.
|
||
- Whether the driver/controller board is integrated with the display PCB or separate.
|
||
- Pi Zero orientation, port access requirements, and whether GPIO/header must remain accessible.
|
||
- Power connector position and desired cable routing.
|
||
- Mounting preference: desktop kickstand, tripod clamp, VESA-style holes, handle, or combination.
|
||
|
||
**Proposed design approach:**
|
||
|
||
1. Create `hardware/display-case/`.
|
||
2. Build a parametric OpenSCAD model with measured display/Pi dimensions.
|
||
3. Split into printable parts: front bezel, rear shell, Pi/controller tray, optional stand/tripod mount.
|
||
4. Validate STLs with OpenSCAD + trimesh.
|
||
5. Upload generated STL/SCAD artifacts to Seafile.
