As for the range problems, I just did an actual range test using the built-in #meshtastic module. I get intermittant coverage on my property (~1/10 acre) and spotty coverage about 30 feet beyond that. Everywhere else is a dead zone.

It's as if the antenna isn't even connected. So when it stops raining and the roof dries off, I'm going to swap out the antenna and do some re-testing to see if I can determine where the problem lies.

I added mounting tabs and tabs to bolt the lid closed for the #meshtastic #solar box.

That makes so much more sense! After re-reading the quote, I think you are right.

It's ambiguous, but after finding some English descriptions about the data dormat for WEEE, that's the only interpretation that makes sense.

RIP 🪦 BitRefill's pre-paid MasterCards. #BitRefill no longer has any digital credit cards that can be used to pay in person. The only option is to have a physical card mailed to you, which is better than nothing, but far inferior to what they used to have.

"According to the WEEE Directive, the EU member states are obliged to collect data on waste electrical and electronic equipment and to transmit this data to the European Commission."

WTF, Europe? Why would you require this extra effort just to invade people's #privacy?

One thing that stuck out was "Fossil fuel power plants generated 85% of the increased electricity demand from Bitcoin mines, including 138 coal-fired and 497 natural gas-fired plants."

Remember back when people used passwords? Yeah that was tedious!

Reminder: The Dead Milkmen

I will not be taking any questions at this time.

In 2022, the Federal Reserve Bank of St Louis started tracking the cost of eggs in bitcoin and USD.

At the time, it showed 18 months of data and illustrated that bitcoin is much more volatile than the USD. Now we have 4 years worth of data.

USD: 1.466 ➡️ 5.897 (+302%)

sats: 4217 ➡️ 6223(+48%)

In just 4 years, using only data from the federal reserve, we see that:

1.) the value of eggs is volatile, and

2.) #bitcoin has lost far less value than the #USD, at least measured in eggs

And even though it has a URL in it, you should never take a screenshot like this at face value! Check to make sure I'm not pulling a hoax on you. I'll even save you from having to type in the URL. https://fredblog.stlouisfed.org/2022/06/buying-eggs-with-bitcoins/

#ProofOfWork. Mixing in rice hulls. Probably have about 4 more houts of work left 'til it's done.

HB1373. And hearing more about HB3632 & HB3566.

Nothing urgent right now, but I like to stay informed about what's on the docket and do my part to keep my rep informed about how people want them to vote.

Oh yes. I have a copy of the designs that they released.

This project is hardcore! #OpenSource, #hardware, #firmware and #software. You can buy pre-flashed hardware.

The catch? It's not clear what components to buy or why, and the setup process is so difficult, it's effectively your new hobby.

I expect it'll get better as out gets more popular and more people contribute to the documentation.

GM. Time to set aside the cross #compiler for a while and switch to #house and #garden projects.

I should be working on mixing rice hulls into the soil of our raised garden beds, but I worked on the open source energy monitoring project. Made progress, but it's not tracking our usage yet.

Tomorrow I hope I can get some rice hulls in between working for the #Artisans #cooperative, meeting with my local elected representative, and helping cook meals for this week. Because it's calling for rain the day after tomorrow.

I managed to get botan (the cryptography toolkit) cross compiled for Win x86-64 (from Linux x86-64). It took all day, but I got it, including even running the test suite under wine to verify it's all correct.

Patch submitted to libbotan to make it easier for others in the future.

Now I'm trying to figure out why the cmake files in keepassxc aren't able to find my newly created botan-2.pc file that defines how to link to the library, what library and header paths should be included

Do people not know about 555-1212?

Apparently that doesn't exist anymore, but the modern day equilivant is (303) 499-7111
