Campervan Controller Case

Part of Campervan

A 3D-printed case for the campervan controller, with room for terminal blocks and a clip for a 35 mm DIN rail or wall mount. It keeps the electronics tidy and secure in the van.

Campervan Home-Automation System

Part of Campervan

The wiring diagram for our campervan home-automation system, showing how the controller connects into the van's power, lighting and controls. It brings smart-home style control into a campervan, built around the power, space and setup a van has.

Campervan Parts List

Part of Campervan

Every part in the campervan home-automation system, from the ESP32 boards to the sensors, current monitor and fuses. It's there so you can price up the system and build your own.

Campervan Power Monitor

Part of Campervan

The schematic for our campervan power monitor: an ESP32 and an INA226 sensor that measure the leisure battery's voltage and current through a shunt resistor. It feeds battery and solar readings into the home-automation system.

Campervan Sensor Nodes

Part of Campervan

How we breadboard the van's sensor nodes: temperature and humidity, door and window reed switches, and a water-tank level sensor. Each one is tested on an ESP32 before getting its own case.

Drone Canopy

Part of Drone

A 3D-printed canopy that covers the drone's electronics and protects the FPV camera. It clips onto the frame so the flight controller and ESC are easy to get at.

Drone ESC

Part of Drone

The schematic for our own ESC (electronic speed controller), which drives the drone's brushless motors. It's the next board after our flight controller and will move on to a PCB design once the circuit is settled.

Drone Flight Controller

Part of Drone

The schematic for the flight controller we designed ourselves for our AI-powered FPV drone. Building our own board instead of using an off-the-shelf one gives us full control over the hardware the drone's flight and AI features run on.

Drone Frame

Part of Drone

A 3D-printed frame for our FPV drone, with motor mounts on each arm and a 30.5 mm stack in the middle for our own flight controller. We're printing and test-fitting it on our own 3D printer before any carbon-fibre version.

Drone Parts List

Part of Drone

Every part in the drone build, from motors and propellers to batteries and the FPV camera and video transmitter. It also lists the boards we're making ourselves, so you can price up your own.

Drone Sensor Breadboard

Part of Drone

How we breadboard the drone's sensors (IMU, barometer and distance sensor) with an ESP32 to test them over I²C. It lets us check each sensor works before it goes onto the flight controller.

E-Stim Breadboard Prototype

Part of E-Stim Device V1.0

The breadboard prototype where our e-stim device started, before the home-made PCB and the V1.0 board. It shows the ESP32, boost converter and H-bridge output as we first wired them.

E-Stim Device V1.0 PCB

Part of E-Stim Device V1.0

The custom board for version 1.0 of our ESP32-based e-stim device, designed in KiCad and made by PCBWay. It replaces our earlier breadboard prototype and home-made PCB.

E-Stim V1.0 Enclosure

Part of E-Stim Device V1.0

A 3D-printed enclosure for the V1.0 e-stim board made by PCBWay, with cut-outs for the control dial and output jacks. It turns the bare board into a device that's safe to handle.

ESP32 DevKit Case

A general-purpose 3D-printed case for a standard 38-pin ESP32 DevKit, with a USB-C cut-out, vents and holes for the LEDs. We use it across our projects for bench builds and quick installs.

FPV Camera Mount

Part of Drone

A small printed mount that holds the FPV camera at an adjustable tilt angle. The angle sets how the drone flies: more tilt for faster forward flight.

Ground Station Enclosure

Part of Drone

A 3D-printed case for our FPV ground station, with a hinged screen and mounts for the receiver antennas. It holds the video receiver, screen, battery and ESP32 telemetry in one unit.

Ground Station Wiring

Part of Drone

How the ground station is wired: antennas to the video receiver, video to the screen, and a 5 V supply from the battery to everything. It also shows where the ESP32 telemetry board connects.

Power Monitor Breadboard

Part of Campervan

How we breadboard the power monitor on the bench before it goes in the van. It shows the ESP32, the INA226 current sensor and the shunt wired up for testing.

Sensor Test Rig

Our reusable ESP32 breadboard setup for trying out new I²C and SPI sensors, with an OLED display for readings. Any new sensor for a project gets tested here first.
