This is awesome, love the python script

I’m going to experiment with my setup some more, but I may go your route in the end.

Using the chest freezer as the tub is ideal because it's already insulated. It takes a couple days to get the water temperature down from room temperature to ice bath levels. But once it's cold, it stays cold. In my setup, the freezer only kicks in once or twice a day to keep the temperature at 45 degrees F.

Thank you for the advice, do you know the specs on the aquarium chiller by chance? I do plan to use a GFCI.

The one I bought is the Active Aqua AACH10HP, which is 1/10 horsepower. There are more powerful models, but they get pretty pricey.

Thanks for the info. I was planning on using a timer and thermostat switch to turn the pump off once reaching target temp and to use gravity to empty the coil when the pump is off.

don't leave the coil in the freezer without flow though, full or empty. It'll freeze the water when you try to start circulation again if it's totally frozen

Most of the DIY stuff I have seen involves putting the water directly in the chest freezer. Would need a much bigger chest freezer to fit in and I’m not crazy about the electrocution risk. I’m currently using the make a bunch of ice approach but it is cumbersome.

You unplug the chest before getting in. It's really not that risky.

The fins are a cool idea!

For those using Aeropress, are you using boiling water? I use 165 degree water...just curious.

They recommend 80°C / 175°F: https://aeropress.com/use-it-now/getting-started/#steps

I believe the water should be just below boiling. I tested it with a thermometer and it seems to settle at the right temperature in a few seconds after boiling, if I open the electric kettle and let it vent.

Almost boiling, up to the point where the kettle really starts to make noise and bubbles are forming.

I just eyeball it honestly. You'll know when you poured the water too hot from the bitter taste :)

I think it depends on beans (dark roast is fine with lower temperatures), but I go with ~99ºC water.

I work with Vue every day at my day job and I spent about 200 hours on the side building an online Svelte course. I really enjoyed the syntax and readability of .svelte files. Local dev environment was a great developer experience and the lack of boiler plate was nice coming from a Vue background.

I built an SPA with an Express backend and my biggest complaint was the lack of an official front end router. The community based router libraries had lots of issues and quirks and I didn’t want to lock into using Sapper at the time. Svelte itself was rock solid though and I look forward to trying Sveltekit (think Next.js for Svelte) in the future.

Anyway, here comes the shameless self promotion:

Here’s a quote I like:

A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyse a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects.

For context, the main characters in that book are kinda immortal. A great book btw

Good information, so we would have a Neural Net that takes a vaccine input and predicts the human (or animal) immune response, and another neural net that generates the vaccine inputs. I suppose the problem would be lack of labeled training data, which is why I was thinking about the chess example which works by simply knowing the rules of the game.
