You can spin up your own mail server.
AFAIK one can recister a domain name anonymously, and pay with lightning. The same is valid for the server (for example via lnvps). That gives you a 100% private email solution. Bonus: you get an unlimited number of email aliases.

Quietly hashing at low cost hours so we can have hot water every day.
(A bit of a crappy video though, sorry about that)

Sometimes I like the physical rush, but not the high. Then CBD is great.

Nice, that means harvast early :-) I thought about planting a few as well in a few weeks. Others are photo sensitive

Are these autoflowers? It seems they start to flower already.

So this is what happens when one does low stress training using a wire that is too thin, and the wind starts to blow.

I am from the Netherlands, we should meet up some time after harvest 😎. Maybe do a tasting session at the Drielandenpunt 😂

Yes, I thought about trying those big growbags this time. They are supposed to be made of breathable material which works well for the roots.
Strain is White Widow. Actually, I found a few seeds between the weed. They seem very potent so far!

Question: what possibilities do you have with the vIBAN?
- Can other people deposit to it?
- Can it be used to pay a bill for example?
Or is it only meant as a gateway to transfer funds to / from a commercial bank account?

What to do with mining residual heat #241: de-ice your kitchen freezer https://image.nostr.build/23d56b6076b6db969d0773aa489c15a7b8d13f72061e7465222e4d3ec903e3fe.jpg

This week I met a guy working for an energy research institute. He told me the wind energy department had to let 20% of the people go because they had to cut costs and this particular department was not profitable enough anymore. The industry is mature and has taken over.
Then I suggested that they could be focusing on enhancing the profitability of renewable energy sources by operating mining equipment in tandem, to stabalize the grid and as a buyer of last resort.
I think I made his day because he was literally laughing out loud.
We are still early so it seems. In this tempo it will cost Europe years to catch up when they get it finally.

If you do it purely for profit home mining is not an option, unless you have access to real cheop energy (<$0.0.6 or so). You also have to invest in equipment and who knows how much it will generate per kWh within one or two years? Could be more if btc price appreciates, but also could be less if increase in hasrate outpaces that.
But building something like this is definitely a lot of fun and you learn a lot of it.

Let's share the results of my home miner project of this winter.
I was wondering if I could package a S19J Pro miner into a usefull piece of furniture. It became a mobile sidetable with a miner inside.
Because it is a prototype i created enough room for electronics. This can be much more compact, but since I didn't know upfront what I needed I made it flexible.
An esp32 is used for reading temp and humidity in the room, as well as the start / stop button, which state it sends to Domoticz.
The esp32 also controls the fans through pwm. That way we don't have to suffer from the noise when the miner boots. It makes it also easy to make it run efficiently when nobody is around, by incrceasing the fan speed. A timer in Domoticz starts the miner in the morning with a high fan setpoint, and switches to a lower fan speed when the first person in the house wakes up.
It has a 230V socket for a laptop for example, and a USB port for charging a phone. The miner is fully remote controlled through Domoticz but also has a local on / off button for convenience. It features a 5m power cable for increased mobility.
Various values are sent to Influxdb and shown in a dashboard.
One of which is the BTC cost price, which is on average 3M/BTC.
So not really profitable yet, but the costs are offset by a slight reduction in heating costs and a huge increase in comfort. The house is heated through floor heating which is quit slow, the miner can quickly heat up the room when requested.

What do you want to use the heat for? With some modifications an old(er) S19J (Pro) can be turned into a quiet livingroom miner. My setup delivers around $0.08 / kWh.
With some more effort, you can embed it into a mobile sidetabel like this one: https://image.nostr.build/afa5b269277d0edab281bb2d489c4db18b7a41878883f7677fb3d1812616034b.jpg

Hey, thanks alot for this idea!
I made a rapid - rapid prototype of wood and carboard to test this and it works wonderfully.
I haven't measured the sound level yet, but it is now at a level that the high frequency noise from the power supply fans are getting more annoying, with chip temperature at around 90 deg Celcius.
Have you considered turning around one of the boards so that the heatsinks both face inwards? I see a 10% higher temperature on the board with the heatsink facing outwards.
