Internet radio with physical controls

What you will work towards

Listen to a few favourite stations without opening an app.

CAIBI’s proposed addition: Verify playable stream URLs, add presets and volume controls, then design the speaker case.

Guide version 1.0. AI can help explain, adapt and debug; you still measure, assemble and test the physical result.

Start with the original

Tutorial foundation

• How To Electronics · open source material ↗

Tutorial located; parts, current dependencies and physical results have not been tested by CAIBI.

See the original source for its photos and demonstrations. We have not copied imagery without confirmed reuse rights. A source prototype is not a photo of this proposed CAIBI build.

Parts to confirm before buying

• ESP32/audio hardware matching the source configuration
• Compatible audio DAC/amplifier and speaker as specified by the source
• OLED, buttons or encoder and protected low-voltage power
• Measured speaker enclosure and fixings

Use the source wiring and bill of materials as the starting point. Confirm exact variants, availability, tools and complete cost before ordering.

The completion route

1. Confirm that one current stream plays using the documented hardware and library versions.
2. Add three verified presets, volume control and visible connecting/unavailable states.
3. Bench-test the speaker and amplifier before designing a case; keep audio wiring away from noisy power routes.
4. Make a serviceable enclosure and check controls, sound and reconnection at the intended volume.

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.

Build on the linked ESP32 radio tutorial. Ask for my ESP32 variant, audio board, library versions and three stream URLs. Check codec support rather than assuming any website URL is playable. Add presets, bounded reconnects, remembered volume with a conservative startup limit and non-blocking buttons.

Ask for measured speaker, amplifier, ESP32, OLED and control dimensions. Design a serviceable desk case with suitable speaker mounting, connector access and separation of audio and power wiring. Do not invent acoustic performance claims.

Create a test log for Internet radio with physical controls. Intended outcome: Listen to a few favourite stations without opening an app. 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.

What to test and record

• Play every preset and record its source URL and date checked.
• Unplug and reconnect the network; controls should remain responsive.
• Restart at a high saved volume and verify the startup limit.
• Check speaker temperature and audible noise at the intended level.

Keep photos, exact parts and software versions with the test log. Failed or incomplete attempts are useful evidence too.

A possible next version

Add station search or network playback after the physical radio is dependable.
