Overview

Wing tester is an open-source printed circuit board by hpvdt, from the hpvdt/load_cell_system repository on GitHub. It is a 2-layer board of 101.5 × 61.6 mm with 50 parts on 68 nets, routed with 365 tracks and 12 vias.

It is built around the HX711 and S8550. Its parts include 18 resistors, 15 capacitors, 6 connectors, 3 ICs and 3 transistors. It belongs with the sensors and measurement boards and the AVR (ATmega, ATtiny) boards of this library.

Load Cell System

System to read up to six load cells and broadcast the data over USB to a host computer that would display and record it. Designed originally for testing wings for our wing profiles for lift and drag.

Hardware designed in KiCad, programmed using Arduino. Code depends on the HX711 library by bodge.

The interface for the host computer is located in our interfaces repository as wing_tester, and is based on Processing 3.

Questions

How big is the Wing tester PCB?

It measures 101.5 × 61.6 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Wing tester use?

50 parts, built around the HX711 and S8550. 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 Wing tester KiCad files?

From the hpvdt/load_cell_system repository on GitHub, at the commit this page was made from: the board is wing_tester_hardware/wing_tester.kicad_pcb and its schematic wing_tester_hardware/wing_tester.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Wing tester design in my own project?

Its repository states no licence, so its author keeps all rights: ask hpvdt before reusing the design.
