Touchscreen for Clough42 Electronic Leadscrew @kentvandervelden

Uploaded October 2020 | Updated September 2026, 2 hours ago

A touchscreen adds arbitrary feed rate and thread pitches to a @Clough42 electronic leadscrew. This work completes the addition of a Nextion touchscreen and a feed-stop switch to the ELS.

$Spectrometer Introduction, Tear-down, and Data Analysis for Plant Phenotyping Spectrometers decompose light into a rainbow of colors and then measure each color accurately. In this video I tear-down a spectrometer, describe the theory, and use of a spectrometer. A recent leaf clip spectrometer is used to for a plant phenotyping application to predict tree lead species.

If you need help with a plant phenotyping project, let me know, I may be able to help your project. The geranium drought experiment is not fully described due to time. Theres additional background information thats needed for understand water absorption spectra. The device used in the video is not ideal for a drought application and so the results are not clear. Let me know if you would more details. The spectrometer that is tore-down is from Ocean Optics. The leaf spectrometer is from CID Bioscience. A Microsoft Surface tablet is used to power the spectrometer and collect data.
