Digger experiment with nidec motor (spoiler alert - contains friction!)

WARNING: This repository contains the early development stages of a remote lab that was never put into full production or testing. You are recommended to use the updated version of the Spinning Disk experiment available at spinner-amax.

Digger

PCB

PCB files are for a version of the PCB intended to work for a number of different hardware setups and used for the Spinner experiment spinner-nidex and therefore does not represent the best design for the Digger alone. There is currently no PCB design for the Digger experiment specifically.

PCB

UI

This version of the UI is an early production version written with Vue 2. The same UI is used for the digger-nidec, governor-nidec and spinner-nidec experiments. In the App.vue file one line of code will need to be changed depending on which experiment you are running:

remoteLabVersion: 'spinning_disk', // or 'robot_arm' or 'variable_governor'

The UI was only ever put into production and tested with the Spinner hardware and development was stopped on the others before they were at a deployable stage. This means that there is no guarantee that the Digger or Governor versions of the UI will work. The UI has been fully upgraded Vue 3 and updated in the spinner-amax repository.

Questions

How big is the EncoderBoard PCB?

It measures 20.3 × 15.2 mm and has 2 copper layers, 1.6 mm thick.

What parts does the EncoderBoard use?

5 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the EncoderBoard KiCad files?

From the practable/digger-nidec repository on GitHub, at the commit this page was made from: the board is hw/pcb/EncoderBoard/EncoderBoard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the EncoderBoard design in my own project?

Its repository publishes it under the AGPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
