Solar Node Cap – Owl Light – LoRa Flat+Angled SCAD

☀️ Solar Node Cap – Owl Light (Bunnings / ALDI)

This cap converts common Bunnings / ALDI solar owl lights into compact solar-powered LoRa / IoT nodes. It replaces the original lens cap and provides a mounting surface for antennas or internal electronics.

The angled antenna version now includes a Face Negative Offset option, allowing the face section to be pushed further inward to create extra internal space for batteries, radios, regulators, wiring, or other hardware.

🔧 Use Case

• LoRa / Meshtastic / MeshCore nodes
• Solar repeater nodes
• Remote IoT deployments

🖨️ Models

Two versions are available:

1 – Flat Cap

A clean, flat mounting surface for antennas or external hardware.
