Hardware case study CyberGadget

Remote control.
Local by design.

RemoteSwitch is a working embedded prototype that turns an infrared remote into a programmable switch. No app, Wi-Fi, or cloud account required.

Watch the design walkthrough How it works

01 / In the workshop

From electronics to enclosure.

The ideaUse a familiar remote to operate a switch without adding another connected service.

The resultA functional prototype combining IR command handling, embedded firmware, and switch control.

02 / Signal to action

A small, deliberate control loop.

One button press connects the physical interface to a switching action. The prototype keeps that path local.

  1. 01
    Input

    Receive an IR signal

    An infrared remote sends a button command to the device.

  2. 02
    Firmware

    Decode & map

    The firmware decodes the signal and maps the assigned button to a switching action.

  3. 03
    Output

    Operate the switch

    The controller triggers the configured switching action at the physical output.

Offline is an architecture choice.

This prototype does not need a network connection or remote account. That reduces network exposure; firmware, command handling, and the physical design still matter.

03 / Development notes

A working prototype.
A clear next step.

Built

Embedded control

The core prototype combines IR decoding, programmable button actions, and switch control. The walkthrough above shows the enclosure design.

Collaboration

Beyond the breadboard

Mechanical design and 3D enclosure work bring the electronics into a physical object, with the enclosure considered as part of the build.

Next to document

Make the build reproducible

Circuit schematics, firmware notes, and repeatable build instructions are the next documentation goals. Component availability and small-batch sourcing remain practical constraints.

04 / Collaboration

Hardware is a team effort.

RemoteSwitch brings embedded development together with mechanical design. Mohamed Ben Hsan contributes the mechanical engineering, 3D modelling, and enclosure design.
