-PV-Mining Box Threadāļøāļø - Part #6:
I saved 16,87⬠by PV mining last month with old and inefficient S9 miners. How the fuck is that possible!?
Letās have a look at my mining rewards of the last month. February 2023. Numbers!

Februaryās weather was surprisingly nice. After all itās a winter month, one of the 4 worst months for PV power production in the northern hemisphere.
Averages numbers per month:
ā”ļø 3,3TH/s hashrate
ā”ļø 273W power consumption.
Averages numbers per day:
ā”ļø 6,5 kWh per day, which were used to heat my livingroom
ā”ļø1011 Sats per day (or 0,00001011 BTC)
Cost:
ā”ļø195 kWh Power consumption by 2xS9 miners
ā”ļø āpriceā of 1kWh of my own solar power is 0,067⬠(as I could sell it for that price to the grid) - thatās 13,13⬠total.
ā”ļø0,00030317 BTC earned in total. ~6,60⬠(at 22.000⬠per BTC)
ā”ļøThatās a loss of 13,13⬠- 6,60⬠= 6,53⬠right?
WRONG! Because I also had to buy 195 kWh of natural gas LESS to heat my living room!
ā”ļøgas price is 0,12⬠per kWh atm (german issuesā¦). So I saved 23,40⬠in heating cost while mining.
𧮠SO IN TOTAL, mining saved me 23,40⬠- 6,53⬠= 16,87⬠in February 2023.
And thatās so fucking cool⦠ā”ļøšš§”š„
And as a side effect I also:
š§” helped securing the finality of BTC transactions and
š§” stole some rewards from C02 emitting miners and
š§” raised the percentage of green mining. It's around 53% atm! Have a look at npub13lkyycj8s3da6fhndtj0wd6s3s2ahmq86s7wrruvzd4tnc66cgfqn4lpsy 's latest notesā¦

Was machen Miner wirklich?āļø

Nostr kann blogposts. Nutzt es!
Hey, why don't you simply publish your Blog article on nostr? Everything you need is there. Bitcoin Audience, Zapps, and Blogspace. Yes, no twitter threads. You can post Blogposts here! Nostrgram.co even offers a filter to only show long posts, aka blogposts...
I'd say private group chats. Or the integration of whitelist Relays in different tabs of your feed/browser?
Do they offer a way for the local citizens to engage in the mining operations? To specify my question: could locals buy miners, place and operate them in the power plants mining room for a small fee?

-PV-Mining Box Threadāļøāļø - Part #4:
Silent S9 Antminers with Noctua Fans? Hear, hear!
As you can hear, the S9 are damn quiet. Vistors barely notice the noise. They rather notice the heatā¦
The Noctua Fans are really making a huge difference here although they do not meet the official specifications for actual mining fans. Thatās the reason why I run each of the S9 on 800W max. Then the Fans run at ~75-80% speed inside of my box. The fans wouldnāt be able to cool the miners sufficiently at higher temperatures or higher wattages. They are too slow.
But thatās not really a downside as the S9 runs most efficiently around 700-900W anyway...
On the picture below you can see that Iāve also added two random case fans to let the air around the PSUs circulate:

If you want do these mods on your own I suggest contacting the community in this telegram channel:
https://t.me/BTC_solo_mining (german guys mostly, but speaking english there should work, too š ) BTW, nostr needs proper group channels so we can leave telegramā¦!
To sum up, at that point my Mining Box was perfectly suited for the use inside my living room. So how much have the miners been heating? Iāll talk about that in the next update!

-PV-Mining Box Threadāļøāļø - Part #5:
100% renewable mining with a private Photovoltaic System (PV) over 6 months from summer to winter?

Let's crunch some numbers! What did I earn? How high was my Hashrate?
Earnings: 0,00359495 BTC. Yeah, that sucks. And it got worse to the end, Bitcoinhashrate always goes up. Halving next yearā¦
Hashrate: something like 3,1 TH/s on average. SUCKS! Even if they only run @800W each, I should get 20TH/s out of them! Why is my Hashrate so low!?
Hereās why. Miners were only running for roughly 6 hours a day.
Many reasons. Wall-o-text incoming!
I've got 46 solarpanels Ć 370Wp, so 17kWp. We don't have a power battery š, as they are fucking expensive! Primarily I bought the PV system to power my families' house, an EV and later on also a heat pump. Last year it produced ~18.000 kWh. Seems to be more than enough to fire up two S9 miners, right? Let's find out...
šÆ šš means: The miners will only be active during daytime. To get as close to 100% renewable mining as possible, Home Assistant is trained to only activate the S9s if there's enough excess power, as we don't want to run the miners with power from the grid (which is not šÆ renewable...).
š¤ļøOn a day in February with a mix of clouds AND sunshine the activity graph can look like this, screenshot is from January:

So even with such a big PV it is not possible to maintain 100% uptime of your miners during winterdays, if you want them to run on 100% renewables...
But there are good days in winter, too, right? Yeah, of course. But those days look like this, and now I expose myself as a blatant liar! 25th February:

You can see it. Itās not 100% green mining. There are peaks of power imports that I donāt care about, when they take less than a minute. Deal with it, Greta!
Key-Lesson of this whole Note?
For all of you dreaming of S9 miners powered by 2*300Wp panels: it will only work with direct sunlight āļø and good angles. Cloudy weather š¦ļøāļø means downtime or grid import...

If you're able to gather this data in a way that the user doesn't notice it, I've got another idea:
Would it be possible to compare your own follower list to the follower list of another user in the moment you have to decide wheter a boost is helpful at all?
Background:
Sometimes I see the same note boostet again and again and get the feeling that half of these boosts are sent to >90% of the same followers.
Clients could prevent showing the same note boosted again and again within maybe 10 minutes, but that would be just another first aid kit...
