A circuit designed, built and tested for the job you have in mind.
- Circuit design and component selection
- Breadboard prototype, tested on the bench
- Soldered build, ready to install
- Wiring diagram and parts list
Our Services
Electronics, campervan systems and one-off maker builds, from first sketch to something you can switch on
01
Electronics & Microcontrollers
Circuits, sensors and microcontroller builds, from a breadboard prototype to something you can switch on and leave running.
ESP32 and Arduino builds, with the code that runs them.
- ESP32 and Arduino builds
- Sensors, displays, relays and switches
- The code that runs on the board
- Wi-Fi and Bluetooth connections
02
Campervan Systems
Off-grid power for a van, and the electronics to monitor and control it.
Off-grid power for a van, planned around how you actually use it.
- Power budget: what you run and for how long
- Battery, solar and charging sized to match
- Wiring diagram with cable sizes and fuses
- Parts list
See what your van is doing, and control it from one place.
- Battery, water and temperature readings
- A display in the van, or on your phone
- Switching for lights and other loads
- Built around an ESP32
03
Maker Projects & Guides
One-off builds, and the guides and parts lists to make your own.
An idea turned into a working first version.
- A conversation about whether it can be built
- A working prototype you can test
- Notes on what we would change next
- Wiring diagram, code and parts list
Guides, parts lists and video walkthroughs, so you can make your own.
- Step-by-step write-ups on the blog
- Parts lists for each build
- Schematics, 3D-printable models and breadboard layouts on our Designs page
- Video walkthroughs on YouTube
- Requests welcome
What we build with
- ESP32

Our Process
How a build runs, from first conversation to handover
Talk It Through
Tell us what you want to build and where it will be used. We say early on whether it is something we can do well.
Plan & Parts
We sketch the circuit or system, choose the parts and agree what the finished build will do.
Build & Test
We prototype it on the bench, test it properly, fix what goes wrong, then build the real thing.
Hand Over
You get the build with its wiring diagram, code and parts list, so it can be repaired or changed later.
