It's mostly from my garden and my neighbors lawns/yards. I have to scavenge some cardboard and other carbon inputs too.

My compost temperature sensor is producing great data, like showing how I put too much rocket fuel into this latest pile:

Interested. What kind of hardware does that take?

I don't understand why everyone is getting upset about the Olympics, censorship, immigration and all the other rage narratives.
Dealing with health insurance in the US should be enough for us to have already burned every single government building to the ground.

Probably. IMO, the purpose of compost is to culture a huge amount of diverse aerobic microbes that cover all of the functional groups in the soil food web. Most compost methods do that very poorly, or substitute long amounts of time to get mediocre results. Almost never does anyone prove the quality of their method with a microscope assessment.
Feedback from temperature data has been the most important thing I've used to improve my compost method and the quality of my hot compost piles. My previous method involved reading a dial thermometer twice a day and recording it in a spreadsheet. This sensor gives me more data with higher quality and less work.

Finished testing the battery on my compost sensor. An 18650 cell (2200 mAh) lasted 3 days when sampling every 15 seconds. This should be more than enough when sampling every 5 minutes for a ~2 week hot compost cycle.

From Strand Tea (who are currently sold out):
Contrary to an advertisement you might have seen in print or on TV, White teas are not just "baby leaves". True White Teas are produced from very specific plants hybridized over generations, always hand made, usually of limited production, and produced for very short duration - sometimes only a few days - and at very specific times of the year depending on the tea growing region. Commonly the new leaf and bud sets from specific tea plants are picked only at a certain hour of the morning under exact air temperature/humidity conditions and then are very carefully handled to avoid any bruising or damage to the leaves.
The two outer leaves are separated from the inner bud. The outer leaves become Bai Mu Dan which is sometimes translated in the Western World as "white peony" due to its smell when fresh. The inner bud becomes the famous "Silver Needle" tea. Bai Mu Dan leaves are usually brewed once, Silver Needle leaves can be brewed multiple times.

I added support for multiple sensors to my compost sensor project.
https://image.nostr.build/bd31f370aca7baf811099f121d93a2eb96f5d7b7ece710360f9da59bca6ec5fa.png
(60C and 992 are the dynamically generated unique IDs for each sensor)
All it took was a weekend of hacking and a PR for the arduino-home-assistant library. But now I can add as many sensors as I want with having to hardcode or update anything on the base station. Just upload the TX sketch onto a new board and go.

Initial testing of the soil moisture sensor is underway, after a few stumbles.

This the raw sensor output, divided by 10. In the air it reads about 32, and submerged in water it's 101. This test shows the sensor in some almost-dry potting soil followed by a watering.

Some big news in AI image generation today.
Most of the members of the image and video team from Stability AI launched a new company called Black Forest and a new model called Flux. Early results look very good. Currently requires 24 GB VRAM, but should be optimized by the community soon. ComfyUI has support already. Their site has a teaser of the upcoming text-to-video model, but it's currently being hugged to death.
https://github.com/black-forest-labs/flux
https://blackforestlabs.ai/up-next/
JoyCaption is a free, open and uncensored VLM built from the ground up. Existing tools are expensive or don't perform well for some domains. Great results for a pre-Alpha. This tool will be extermely useful to enable more community fine-tuning and training because producing captions for datasets is very time-consuming.

ollama seems to load as much as it can into VRAM, and the rest into RAM. Llama 3.1 70b is running a lot slower than 8b on a 4090, but it's usable. The ollama library has a bunch different versions that appear to be quantized: https://ollama.com/library/llama3.1

Yes, it will receive data from the sensors over LoRa and forward them over wifi. I'm using Adafruit IO to store the data and provide charts for this prototype, but MQTT to Home Assistant should be easy.

Started a new compost pile a few days ago...
https://image.nostr.build/b4a02f0c6da58100747069f7a484527b36dab79357b988303da95f5757081881.png
Rather than mixing everything on a tarp first, the ingredients went into the bin in single-bucket layers. Every few buckets I added a handful of cottonseed meal and cheap cat food for high nitrogen. It seems to be heating up nicely.
The first turn showed the inside was a little dry, which I think was indicated by the temperature dropping rapidly right before turning. Getting the moisture level right is harder when it's not mixed on a tarp first.

I found a variety of nematodes in a compost sample last night:
https://nostr.build/av/f24b39a9ffe5609a283838e3bf44746c07db7e99c9fb4787b04691ee41e54c9c.mp4
You can see this one swallowing. I got to see it poop too, but didn't get it on video. Nematode poop is one way that the soil food web cycles nutrients to make them plant available. Nematodes can eat 10,000 bacteria per day. They excrete the excess nutrients from the bacteria in a plant-available form.

Seeing three different kinds of nematodes in a single drop from a compost sample is a good sign. This compost sample had lots of protozoa and fungi too. It was a little low on flagellates, and the organic matter wasn't fully decomposed. Still, I'm very impressed with it for being only four months old and never turned.

Numeric values for each reading. This is the basic Home Assistant card. https://m.primal.net/HIRi.png
Tapping any of those readings will open the basic Home Assistant graph. It can show more history but takes a few extra taps. You can see here the spike in soil moisture after I watered the sensors.

Have you seeded them with anything? It's good to get a fast growing cover crop to hold the soil together. Geoff Lawton plants everything in the swale mound right away: quick cover crop, shrubs and trees. And plenty of mulch.
