To consolidate and rigidify the circuitry bespoke printed circuit boards were designed using circuit design software tool Fritzing and then fabricated at a low volume PCB manufacturer, Aisler. A design strategy commonly employed in the single board computer arena was used -a Pi HAT (Hardware Attached on Top) circuit board was designed to contain all the control electronics in an easily attachable/detachable board. A second smaller circuit board was designed for the detector and LED.
