Data Sample for Download - Conifer (Picea abies) TOP NEW
Conifer (Picea abies) Sample Dataset Download it from zenodo To request access to the full dataset send an email to phyclops at protonmail dot com. Note that this specific collection of electrophysiology recordings contains unwanted noise, but it can still be useful for getting a ‘feel for the data’, which is why we make it available here. For... Read More

Indoor testing of two 'Minions' with new AmpV4 TOP NEW
Indoor testing After calibrating two amplifier Version 4 boards and hooking them up to the microcontroller two new cases were built. Unintentionally they turned out to look like Minions, which is why I am tempted to call them just that. The goal is to set them up over the next couple of days in a new field location. One will be connected to a... Read More

Amplifier Version 4 is good to go TOP NEW
Amplifier version 4 is ready After a week of design work, 3-4 weeks of prototype testing on a breadboard connected to an Avocado plant the final design was sent out to the company doing the fabrication. Just three weeks later I received the five amplifier boards that I had orded and, to my great relief, they all worked as intended (phew). Read More

Designing a New Amplifier TOP NEW
Amplifier version 4 is taking shape It is time to look at improving the amplifier design and to come up with a better, less noisy instrumentation amplifier that I can use in outdoor and indoor plant electrical recordings. Since the amplifier is, in my view, the most important component of a recording device, it deserves a lot of TLC :) Read More

Olive Tree - Detecting Drystress with Machine Learning TOP NEW
Electrical Signals of a dry-stressed Olive tree It is possible to detect the irrigation state (dry/irrigated) of an olive tree by analyzing the recorded electrical signals. It is important to note that this detection method can sense dryness well before it becomes apparent e.g. through wilted or discolored leaves, sagging branches etc. Read More

Intro - Recording Electrical Signals of a Wild Conifer TOP NEW
Intro - Recording Electrical Signals of a Conifer in the Wild I am starting a long term electrical recording of a small wild conifer (Picea abies) in the austrian Alps. Electrophysiology and environmental data will be collected for one entire year. As of January 2024 a data sample is freely available for download (see the download section). F... Read More

Hardware TOP NEW
Amplifier Version 2 - Schematic This simple amplifier has two channels, each one requiring just two OpAmps, two potentiometers and one resistor. It is a DC voltage amplifier where the lower and upper bound of the input range can be adjusted, for example to -500 mV and +500 mV. It outputs a voltage between GND and VCC (3.3v). Before you build thi... Read More
