Those things grow incredibly well here. You won't be sorry.

I have some ansible files that will set up Frigate for you. I'd love to help you with your setup in exchange for you taking notes that we can publish as a guide. Everybody wins.

Ypu don't find them visually confusing? That anyone would be able to tell at a glance which symbol that're looking at?

I've used 3 different models of Lulzbots and 3 models of Enders. Honestly, I'd recommend an Ender 3 v3. Unless you need an absurdly large build plate, in which case, the Ender 5+. They've been extremely reliable, easy to use, and they don't send your prints off to the manufacturer (like Bambu does). Now, if you are going to do extremely detailed, small things (like D&D minis), then my recoendation doesn't necessarially hold. I believe a resin printer is your best bet. I'm going to switch an ender 5 over to a 0.2mm head as soon as the heads arrive, and I'll probably post here about how well it prints with the smaller nozzle. Hopefully that'll let it do the tiny details.

Another day of training. Not cardio. Not strength. Modeling skills training. As in the 3D modeling sense. I've been working on some new cases for #meshtastic configurations where I haven't been able to find an existing case. For example, the RAK 13000 with a screen. I can find cases without the screen, but none with. It might be an indexing problem, or blame me for searching for the model number instead of something else. But it's good practice to make custom models. Sharpen those skills.

So lets price it out: Solar panel + charge controller $93 https://www.amazon.com/Traver-Monocrystalline-Renogy-Charge-Controller/dp/B0D59F4MJY Battery $123 https://www.autozone.com/p/totalpro-battery-24ms-t/1006724 Buck converters $23 https://www.amazon.com/DROK-Converter-Waterproof-8-35V-Adjustable/dp/B0DMP1KCWP?xpid=rdhR9EO5I3SuP Plus some wires and mounting gear which I'll boldly assume you have lying around the house. About $250. Plus I think the miners go for about $100. All in all, $350 total but with no solar tracking and no graceful miner shutdown/resume. You could probably rig up a relay between the battery and the miner that would be held shut by the battery, then when the battery voltage drops too low, it'd open the circuit. Oh snaps. I just realized the solarbit €600 solar bit doesn't include the solar panels, battery, metal frame or miner! Now I understand why you called it expensive! Well shit man, want to go into business making kits that are less exppensive and include all the parts except batteries (b/c it simply doesn't make sense to ship big heavy batteries)? We could open source the design and let people choose to DIY or buy something from is that is ready to rock.

OK, so that's 30W constant draw, which means 720Wh per day. If we assume we get 8 hours of full sun per day, which is reasonable if you have a fixed angle on your panels and not a sun-tracking system, that means you need to have 3x that power to go 24/7. That's too much power for lithium batteries to make sense, go with a deep cell lead acid. You'll want the following: Solar panels (2160 W minumum) Charge controller Battery (60Ah @ 12V minimum) Voltage regulator (12V -> 5V @ 6A) You can get a pair of 3A buck converters for voltage regulation and run them in parallel if necessary. If you want to be able to tolerate cloudy days you'll need more battery capacity. If you want to tolerate winters, you'll need more solar generation capacity. If you don't want to completely run your battery into the ground every day, you should get at least 20% more than the minimum. I tbink that about sums it up. Deep cell marine batteries are available at your local auto store. Everything else will probably come from the internet. I'll let you do the lrice shopping.

I'm not sure what the current draw is on those, but if you LMK I can help with the calculations. And are they 5V or 12V? Oh, and are you cool with it being down if there are a few cloudy days in a row?

Side note: this particular board is not a . 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. 😅

I'll try to remember to check back again later. I'm following you now, so you'll show up in my timeline and I'll beore likely to remember.

Apparently you can only rent Hummingbird in USD and only pay-per-second with lightning. Heaven forbid anyone want to rent it using lightning, or (gasp) actually buy a copy so they can watch it offline. I like the idea of IndeeHub, but I'm unimpressed by the implementation.

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. 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 180°C and make sure all of the parts are properly aligned while the solder is still liquid. 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. ❤️

It's kinda funny that we're down to 2 browsers again and neither are Netscape nor IE. The more things change the more things stay the same.

What was that bookstore on here that took lightning payments? Their big advertising thing was that books got less expensive (in sats) over time.

Not a bad idea. I'm not sure saving $27 (if I wait for a sale) is worth the time and effort to do that. I decided to try to take a quick peek though From some random website: "On Tuesday, arabica coffee fell to a 19-month nearest-futures low, and robusta slid to a 2-month low, amid an outlook for a bumper coffee crop this year in Brazil." From that same website: "Coffee prices settled sharply higher on Wednesday as short covering emerged after the Japan Meteorological Agency confirmed an El Niño weather pattern had formed across the equatorial Pacific. This sets the stage for months of floods, droughts, and temperature fluctuations later this year that could hinder coffee production in Asia and South America." It seems there's some skill involves to determine which of those (completely opposite signals) is relevant/accurate. Also, these seem to be for July prices, which is very near term.

I decided to wait to place my order. We probably have about a five month supply left, and they run 10-15% off sales from time to time. Time will tell if this was a sage decision or a foolish one.

I've been making and using open hardware for years. Happy to have people join the lifestyle. 😎 One thing to watch out for is whether eveything is published. There are some great projects oit there, and then some who try to get the credit without being true to the spirit. Examples: - Publish STL files, but not the model they were exported from - Publish the grebers, but not the eCAD that generated them - Publish the code, but not the build scripts Seeing only one vendor of an open source hardware project is a warning sign. Why isn't there multiple manufacturers in competition? Maybe it's a lack of demand, or maybe it's because there are barriers to entry (intentional or otherwise). In general, I'm not a fan of certifications, but I gotta say, the Open Source Hardware Association holds the line. If they say it's legit, I'll believe it without feeling the need to dig into the details myself. And certification doesn't cost any money. It's not that racket. They have a value for value model, where they do the work and hope that people will join as members ($25/year). Ultimately, doing it yourself, at least once, just to prove to yourself that you can, is the ultimate test. Then you know you can deal with the project going away. But that takes a lot of time and effort.

Understandable. Sad. I wish I had an alternative solution to suggest, but by the looks of the thread you've already considered it all (paid uploads, PoW, automated detection, etc.)
