@ZEUS came through for me again at Steak & Shake. 40K sats in value, 21 sats in fees. Nice.

Remember, the American independence day is celebrating the declaration that we were free from of British rule. The country wasn't actually formed until May 29, 1790, when the constitution was signed. These states were not united until that point. This means the county won't really turn 250 until the year 2040. Sorry to bring facts into this emotional topic, but if you care to celebrate these historical events, you really should know what it is you are celebrating.

My mission today is to plan out an automatic, off grid watering system for our garden. - โœ… 305 gallon rain barrel - ๐Ÿ‘€ 12V water pump - โœ… Solar panel - โœ… Charge controller - ๐Ÿ‘€ 12V deep cell battery - ๐Ÿ‘€ Drip irrigation system - โœ… Water valve timers - ๐Ÿ”จ Box to contain it the electronics The plan is to have it work perpetually without relying on grid power or municipal water. It will also be repairable and maintainable. Powered by #solar and #rainwater. #SelfReliant #homestead

How do I use @kidwarp's vanilla bean paste? Today I used it in cream cheese clouds. image 1 lb butter, softened 1 lb cream cheese, softened 1/2 cup powdered swerve 4 tsp vanilla bean paste or extract Wisk them together with the stand mixer, starting slow and working up to max speed for 1 minute. Plop onto a cookie sheet in 1 Tbsp chunks, and freeze for an hour. They're done. Box 'em and put them in the fridge or freezer.

I think "Videoรผberwachung" might be my favorite German word. Even if you don't know the language, you can probably still figure out what it means. View quoted note โ†’ Related: I'm also enjoying attempting to read posts in German even though my vocabulary is like a hundred words. After I read it and form a hypothesis on what it might say, I'll use some tool to translate it and see how far off I was and fill in the words I didn't know. It's a fun way to try to learn a new language. ๐Ÿ˜Ž

If you want to introduce someone to the ideals that: - technology should benefit people, rather than to exploit them - information should be free instead of being controlled by gatekeepers and - privacy is better than mass surveillance Buy them a copy of the novella "Connection Timeout". The author (Rek2) is the real deal. While the story is fiction, it's setting it not. The tools he talks about are real. They exist now. He got the tech and the ethos exactly right. From LoRa based mesh networks to the intrusion tools, the tactics and techniques, the mentality... it's all spot on. It's a great way to introduce friends and family to the ideas of freedom tech. It's not a lecture about what they should or should not be doing. It's a fun story about a hacker who is dismayed with the state of the world in 2030. Cameras don't just use facial recognition and gait; it got much more invasive. Boost this note to spread the message. #freedom #tech #FreedomTech #hackers

To anyone who followed me because I post about home made electronics and are now seeing me post about off-topic things like black raspberries, real economics, and lightning payments... That's what you get when you follow me. I am not a brand. If you don't want to see some of these things, feel free to mute whatever words make sense. You should get what you want in your feed, and I'm going to keep posting about what I do. โค๏ธ

Proof of work: 1.25 lbs of black raspberries. Homegrown and hand picked. image Fun fact: strawberries are apparently way more dense than black raspberries, which I was extremely surprised to learn!

The only good review is an honest review. I tried to use @ZEUS wallet to pay at Steak 'n' Shake today. It did not go smoothly, but that may be my fault, at least in part. First, it failed. I manually bumped up the fee and retried. It failed again. A third time, this time also selecting the first hop. It acted like it was going to work, but just hung at the sending screen. The cash register timed out, then Zeus timed out. I tried again from the register, scanned the new QR code, selected the first hop, cranked the fee way up, and it sailed through exactly as I'd have liked to have seen the first time. In the end, I believe the core issue was the default fee being too low. I just checked my settings and it was set to 0 sats, 0%, so it looks like these failures may have been my fault. I've adjusted these to reasonable numbers and will continue to report back as I use the wallet with real world transactions. Shout out to @EVAN KALOUDIS for putting in the work and helping people on social media when they have issues. ๐Ÿค™

Side note: this particular board is not a @Signet. It's a board to convert between a USB keyboard and a computer's PS/2 port. Why? Security. Having a PS/2 keyboard allows blocking all USB keyboards from using dom0 in Xen (in my case, on QubesOS). That means if I plug in a malicious USB device that acts as a keyboard, it can't send keystrokes to take over the entire computer. It's a very specific use case and I've sold exactly one of these boards, vut to the people who want them, they're very valuable, and much cheaper than the closed source alternatives, too! It turns out, once people pick up the skill of making custom PCBs, they rarely stop after just one board. ๐Ÿ˜… View quoted note โ†’

Not sure if any of my followers are interested in how stuff is made, but if so here's a pic of electronics assembly. More specifically printed circuit board (PCB) assembly. image The metal is a solder mask so the solder only goes onto the metal pads on the board. It's thickness determines how much solder is applied. Too much, you get a short circuit. Too little and the component falls off. Here's what it looks like after the solder is applied and after the component are placed. After that, just put it on a hot plate or an oven dedicated to electronics, heat until 180ยฐC and make sure all of the parts are properly aligned while the solder is still liquid. image And that's pretty much it for surface mount soldering. These boards also have through-hole components, but that's a more common skill, so I'll skip over that for now. If you found this interesting, give this not a boost so others can enjoy seeing how PCBs are populated. โค๏ธ
