A handheld plastic identification tool

A handheld version of the PlasticScanner as a part of a master thesis at DTU

Warning This is under development and should not be reproduced before a release is published or if you want do develop it yourself.

Our mission

We believe that plastic sorting and recycling can be improved. Our handheld Plastic Scanner enhances the process by immediately identifying various plastic types. It can be used in both residential and large waste management settings.

The handheld Plastic Scanner

A compact handheld Plastic Scanner that contains a small breakout board with ADC, amplifier, LED controller and a color sensor, that can be effortlessly interfaced using the Qwiic/StemmaQT I2C connectors.

Changes from the original Plastic Scanner

The board has the following changes from the original:

  • The ADC ADS1256 we interfaced SPI is exchanged for the NAU7802 ADC that we interface via I2C
  • AS7341 I2C color sensor added
  • 5v changed to 3.3v to comply with Qwiic/stemmaQT guidelines

Notes

  • Holes are M2 holes (iso 7380)

Questions

How big is the Power PCB?

It measures 94 × 140 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Power use?

131 parts, built around the ESP32-S3-WROOM-1-N8, AS7341-DLGT, NAU7802SGI and TLV62569DBV. 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 Power KiCad files?

From the LokiMetaSmith/handheld-scanner repository on GitHub, at the commit this page was made from: the board is Hardware/Power/Power.kicad_pcb and its schematic Hardware/Controller/ControllerBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Power design in my own project?

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