Enter the signal
A telegraph-style key, buttons, dial or other tactile control can turn dots and dashes into deliberate player input.
PF–BUILD / 02 Past build + custom commissions
A Morse code radio puzzle with signal and soul.
An encoder and decoder in the style of an old-school radio: tactile controls, audible signalling and a message that feels received rather than merely displayed.

Signal path / 01–04
A simple code becomes a physical discovery.
Morse works because it crosses sound, rhythm, language and touch. The prop gives each part of that translation a tangible place in the experience.
Hear and see the pattern
Audio, indicator lamps, a meter or display can give the signal character while keeping timing legible.
Decode the message
The puzzle can ask players to translate a received phrase, check an entered message or pass information between separated stations.
Trigger the world
A correct transmission can release a lock, reveal a clue, update a room controller or start the next sequence.
Built around the puzzle, not just the alphabet.
A custom Morse prop can control how much players need to learn, what operators can change and how clearly the system responds.
Messages and modes
Fixed or configurable phrases, encode and decode modes, and integration with the wider game state.
Speed and tolerance
Playback pace, input timing, hints and validation can be tuned to the intended audience.
Sound and controls
Knobs, key feel, meter movement, tone and enclosure design establish the radio personality.

Feedback
Audio plus visible pulse
Characterful meter, lamp and tuning behaviour
Audio can carry the mood without carrying every clue.
If the brief needs broader access, a Morse interaction can combine tone with visual pulses, a meter, printed support or another parallel cue. The right option depends on whether listening is the theme, the challenge or simply the atmosphere.
- 01 / Hear
Characterful tone
Sound establishes the radio identity and rhythm of the message.
- 02 / See
Parallel indication
Lamps, displays or meter movement can mirror the signal where appropriate.
- 03 / Learn
Useful support
A reference, hint path or practice state can calibrate the intended difficulty.
- 04 / Confirm
Clear response
The prop should reveal whether it heard, accepted or rejected an entry.
Before we tune the dial.
Does the prop transmit a real radio signal?
It does not have to. The radio experience can be simulated locally with audio and wired or short-range communication. If genuine radio transmission is part of a new brief, the frequency, power, equipment and applicable UK requirements need to be defined before choosing an architecture.
Can the message and difficulty be changed?
A custom build can be designed with configurable messages, playback speed, timing tolerance, hints and feedback. The exact operator controls are agreed in the brief.
Can the puzzle offer an alternative to audio-only play?
Yes, if it is included in the interaction design. Visual pulse feedback, a meter, printed support or another parallel cue can reduce reliance on audio while preserving the intended puzzle.
