I am currently exploring the sonification of weakly electric fish, such as the Black Ghost Knifefish, partially cos it's fun (see ENKI, by Tony Hall). but there is examples of using the frequency analysis to monitor water quality
- 1 Basic Setup
- 2 Fish 2 pd Interface
- 3 Fishuino aka Arduino based direct Hz, gender and chirp detection
- 4 First Sonification experiment
- 5 Merchandise
- 6 Literature on Biomonitoring using weakly electric fish
Nice travelling edition for the HLab14 Tourdigrade
Version 0.1, exploring a simple LM386, with 200 gain (the extra 10µF cap) and adding another locally available cheap PowerAmp kit from the electronics store, Audio. works fine... using a small 12V battery to remove weird 50Hz hums form the lifepatch crap cabling listrik staayle.
Maybe i should use an instrumental differential amplifier? like this one (luckily i have a bunch of them in my Mobile Lab)
Inspired by these BioSignala she-geeks in the UK
More info about Op-ampology
I am just slowly trying to understand all that shielding issues... learning from wikipedia
Cables and electrodes
from openEEG and olimex
Fish 2 pd Interface
Download patch: File:Fish_oscilloscopeNew.pd.zip
Fishuino aka Arduino based direct Hz, gender and chirp detection
Seemingly you can detect the gender of the knifefish by analyzing the chirps, frequency shift, amount and duration.
using our recent frequency counter that works on the BabyGnusbuino aswell as the Arduino, we might build a standalone detector - visualizing unit. More about Frequency measurements
IoF aka Internet-of-Fish
Let's connect them through the internet!
Using the FreqMeasure library from paul
and the groove 4-digit display, which can be adressed by software serial:
Fishuino on GitHub
working on it...
First Sonification experiment
Please note that the clicks are not communication, but wiggles in the wiring... see chrips in the pic above, detected with pd.
I am planning to make some nice crafted device for selling it in some local aquarium stores in yogyakarta. and of course a t-shirt
