An RGB matrix display with a rotary control for information and audio experiments.
CAIBI’s proposed addition: Choose a single useful screen first. Compare adapting the original electronics with a simpler existing matrix controller.
Start with the original
Creator build
Article reviewed 19 October 2026. Files and physical performance have not been independently validated. Not built or assessed by CAIBI.
From source to something you can finish
What the source provides: A creator prototype, hardware list, schematic and enclosure/code sections for an ESP32-S3 matrix device.
What still needs doing: Download and verify matching files, dependencies, data-service access and the required fabrication. Listed features are creator claims, not CAIBI tests.
Your first milestone: Confirm the firmware can build and identify a suitable power arrangement before buying the full hardware.
Prompts to move it forward
Copy a prompt into your AI tool with the source material and your actual parts. Work through one small step at a time and check the output before using it. Choose an AI tool or practise the skills first.
Check the source before buying
Review the source material I supply for Pixlpal: a colourful desktop information display. Make a table of what is provided, missing, contradictory or dependent on a paid service. Identify exact hardware revisions, firmware files, library versions, CAD files and licences. Separate creator claims from your proposed additions. Do not fill gaps with guessed specifications. Finish with one small test that can resolve the biggest uncertainty before I buy parts.

Plan the next step
I want to develop this idea: Pixlpal: a colourful desktop information display. Intended outcome: An RGB matrix display with a rotary control for information and audio experiments. The source is https://www.hackster.io/537143/pixlpal-interactive-aiot-display-db1c8d. CAIBI suggests: Choose a single useful screen first. Compare adapting the original electronics with a simpler existing matrix controller. First inspect the source I supply. Separate what it already does from proposed additions. Ask for my actual board, parts, skill level and missing files. Produce a small staged plan with one bench test per stage. Do not invent pin assignments, dimensions or completed test results.

Design a measured enclosure
Help me design a practical enclosure for Pixlpal: a colourful desktop information display. First ask for measured component dimensions, mounting holes, connectors, cable clearance, ventilation and operating conditions. Suggest a printable or off-the-shelf approach. Begin with a fit-test piece before a complete case. Label assumptions and do not invent an enclosure rating.

Check and document the result
Create a test log for Pixlpal: a colourful desktop information display. Intended outcome: An RGB matrix display with a rotary control for information and audio experiments. Separate expected behaviour from observed results. Include power restart, disconnected inputs, communication failure and the actual physical use. Ask me to provide results, firmware versions, changes, photos and unresolved problems. Never mark a test passed without my evidence.
