PCB Design & Assembly

• Schematic capture and layout in KiCAD, Eagle and Altium, from sensor front ends and power stages to compact, potted boards.
• Hand soldering and reflow assembly, followed by bring-up and rework on the bench.

Mechanical Design & CAD

• Enclosures, pressure housings, potting moulds and full assemblies in SolidWorks, Fusion 360 and PTC Creo.
• Designed for the process that will make them: machined, printed, cast or potted.

Machining & Rapid Prototyping

• Manual and CNC machining: lathe, end mill, water-jet and laser cutting.
• FDM and SLA printing, vacuum moulding, potting and circuit encapsulation for wet and high-pressure environments.

Embedded Firmware

• Bare-metal and HAL firmware on STM32, Nordic, Espressif, Atmel and Padauk microcontrollers, in Arduino and Segger toolchains.
• Sensor acquisition, motor and pump control, low-power scheduling, and CAN, UART, SPI and I²C buses.

Wireless & IoT

• Field devices that phone home over LoRa, cellular TCP/IP, ARGOS satellite and BLE, with GPS positioning and cloud logging.
• Designed for the link budget and power budget of places with no infrastructure at all.

Test, Debug & Instrumentation

• Circuit debugging with oscilloscopes, spectrum analyzers and logic analyzers.
• Material and device characterization: Vibrating Sample Magnetometer, Instron push-pull testing, sputtering and vapor deposition, hydrostatic pressure testing for deep-water simulation.

Control, Modelling & Software

• Analog and digital control systems; MATLAB/Simulink for modelling and LabVIEW for instrument control.
• Enough software to make the hardware useful: C/C++ on the device, Python for tooling and data, Kotlin for companion apps.
