Part 2: Power supply 230V & Solar

Power supply via 230V: The simplest and cheapest solution Then you see immediately if something shifts when screwing on. Self-tapping tapping screws with drill point: When screwing on, make sure that the two axes of the hinge are aligned (longitudinally aligned), otherwise it will jam later! 2x gate hinge for variable installation angles, screw on centrally. => The… Read More »

Part 3: Adapter-LK for Grove connectors

Basics of the Grove connector system. Why Grove plugs? A table top assembly (almost) only with finished Grove modules. Solderless connector system This greatly reduces the chance of miswiring. No forgotten pull-up / pull-down resistors… A repair / component exchange extension / troubleshooting at the apiary is also much easier due to the “reverse polarity protected” plugging. If… Read More »

Part 4: Assembly of the scale frame

Here I have chosen the following structure: One screen printing plate each at the top and bottom. It is screwed onto a 100x200x10mm steel or aluminium plate for load distribution. Between the load distribution plates there is a spacer plate on each side which is adapted to the bore pattern of the load cell. At each of the… Read More »
