Build update for the scale:
Not deterred by the provincial lockdown, production of the scale has continued. Unorthodox materials have been sourced to continue with a minimum viable prototype. Craft sticks and hot glue work in a pinch, but the surface will have to be upgraded to an acrylic or equivalent material to provide a clean look.
Pictured are the strain gauges soldered together to connect to the HX711 amplifier. The amplifier is connected to the raspberry pi. Craft sticks make up the surface of the scale in addition to the mounts for the strain gauge. Wiring is rudementally managed with tape and cable management ties to avoid any accidents during development and testing.
The next scale update should include the software design required to interface with the open source drivers for the HX711 amplifier with the rest of the system.
Happy Groundhog day!
