The human microbiome is a big deal. We can have as many as 100 trillion microorganisms living simultaneously in our gut. These gut microbiota outnumber our genes by nearly 150x turning homosapiens into a “superorganism”. What are all these microbes doing? They help us digest by fermenting our food. They also have been shown to produce some powerful neurochemicals that have the ability to communicate with our brains. The neuroreceptors inside our intestines and the vagus nerve are the gateways to the brain.
The big three are neurochemicals that are related to our gut and regulate our mood are the following:
dopamine (~50% produced in our gut) – pleasure
serotonin (most of it is produced in our gut) – relays messages to cells related to mood, sex, appetite, sleep, memory and learning
GABA (gamma-aminobutyric acid) – calming
How can you hack your mood through your gut? It is still the Wild West in terms of neuroscience studies coming out on this topic. My personal choice is to eat a ton of fermented foods. Kombucha, water-kefir, ginger beer, sauerkraut, kimchi and some commercial liquid probiotics that I perpetuate. We will get more into biohacking with fermented foods on future posts. A new term for these microbes which can benefit the brain and our behavior are psychobiotics.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

Can I get some background on those fermentation controllers?
I’m working on a kefir and yogurt temperature controller. But I would love to take advantage of something already existing.
@Tilman Baumann – That is a YATC5 temperature controller. I wrote up this post and happen to be the person who designs and sell those controllers. I was trying to avoid hyping my personal stuff, but since you ask: screwdecaf.cx/yatc.html
It’s all OSHW…
Looks pretty good. But is perhaps not quite what I was looking for.
I would prefer to have a PID. That should be fixable being open source and all.
But also the board turns out would not quite fit the appliance where I would want to embed it into. With the resulting ratsnest of wires to make it fit, I’m not far off from the breadboard solution I’m working on.
