Assessed 2026-11-04. ## Project ideas - A tiny viewfinder for your Ricoh GR ## What you need - M5Stack StickS3 - Required: Supported RICOH GR camera. Choose ONE: GR II, GR III/IIIx or GR IV under the repository’s model-specific support matrix. Link is GR IV only; not a recommendation to replace an existing camera. - Required: 3D-printed StickS3 hot-shoe mount. Use STL/STEP from the repository cad folder; do not assume a generic cold-shoe adapter fits. - Required: USB-C data cable. A charge-only cable cannot flash firmware. Example requires a USB-A host port. If your computer has only USB-C, use an appropriate USB-C data cable instead. Reuse the device’s included cable where possible; this is not a standalone power-supply recommendation. - Tool: Computer for setup. ## Compatibility and cautions - Requires model-specific pairing, firmware and a printed mount. Creator reports physical tests; directory has not repeated them. - Source-reviewed, not independently hardware-tested. Confirm the model, revision and recovery process before changing device software. ## Buy [Search Amazon (unverified)](https://www.amazon.com/s?k=M5Stack+StickS3) — Search destination only; matching listing NOT verified Search fallback only.

Creator reports physical tests; directory has not repeated them. 3. **Start with a reversible test**: Follow the linked project source before changing the device. Back up existing configuration, keep credentials private and stop if your hardware differs from the documented version. ## Coding-agent project brief Help me plan a tiny viewfinder for your ricoh gr using M5Stack StickS3. Read https://youcanjustbuildthings.openai.chatgpt.site/projects/submission-c2ac6e11f54cc9e37f847dda361f3ccefde2cecb6fc800bd6c0cbddc0619cf38 and its supporting sources first. Firmware on the StickS3 receives live view from a supported Ricoh GR camera and sends shutter commands. Requires model-specific pairing, firmware and a printed mount. Creator reports physical tests; directory has not repeated them. Confirm my exact hardware and required accessories, explain what is missing, and propose one reversible test. Ask before flashing firmware, changing privileged system settings or moving physical hardware. ## Common questions ### Where does my software run?
