Software and instructions for setting up and running a self-driving lab (autonomous experimentation) demo using dimmable RGB LEDs, an 8-channel spectrophotometer, a microcontroller, and an adaptive design algorithm, as well as extensions to liquid- and solid-based color matching demos.

Alternative demo ideas #13

In a similar vein to a Rubens tube, vibrating a drumhead or a liquid surface and trying to match particular harmonics using speakers as inputs (a 2D signal example).

In a 3D signal example, measuring WiFi strength in 3D Euclidean space (maybe with separate sensors) where the WiFi source positions and/or sensor positions can be adjusted, and trying to match a target distribution of the WiFi signal. Starts to become reminiscent of DFT relaxation, where multiple local optima may start to appear. See also https://www.google.com/search?q=wifi+heatmapper

In a materials example, perhaps liquid suspensions of particles that are being stirred, mixing the solutions, and measuring the packing fraction (visually?) of a dried solution based on drying temperature and composition? Wash out the container with vigorous mixing and then extract the waste into a waste container (all via peristaltic pumps most likely).

Might want to look at other low-cost sensors for chemistry, physics, and materials science that might not appear on Adafruit. pH is a nice idea one that appeared in one of the papers.

EDIT: nice example of motor control with an RPi Pico W

@Gadgetoid, came across your profile, and very nice work with pinout.xyz.

I figured it might be worth asking, any thoughts on this project? I'm particularly interested to hear your thoughts on alternative demos (hence tagging you on this thread), modifications that you think would be interesting, and suggestions on how to maximize impact.

In terms of a cheap sensor setup, you could use an infrared camera to validate/monitor reactivity of substances in terms of exothermic heat -> Optimize towards most even reaction or highest peak, reaction duration etc.

Another one would be the stirring plate voltage/current to measure rheology.

@BAMcvoelker great suggestions!
