OK, the angle wasn't sharp enough on my first attempt, so I re-did it. I also added the screw hole in the bolt so I don't have to drill any plastic. I have a specific plan on how to use these and if it works, it's going to be glorious! Stay tuned. Remixed from: #3DPrinting #manufacturing #art

How do I keep my RAK #meshtastic from going into sleep mode? It's configured as a router and power saving is off. I don't know what more I can do here... It's supposed to be a router. I wasn't it listening at all times and I don't give a hoot how much power it uses. No packets left behind!

image The bolt is going to get screwed to the ceiling (or wall) and then the tentacle can be reaching out of the ceiling (or wall) with no visible attachment points. It can also be more load bearing than if it was just taped onto the ceiling/wall. The large bolt is about as thick as my pinky finger. I forgot to put something in frame for scale. #3DPrinting #FreeCAD

I'm not exactly sure what the capacity of my 26700 batteries are, but it's likely around 5Ah. I was planning on putting 8 of them in my #meshtastic #solar node (two banks of 4 batteries). So in the ballpark of 40Ah. I just saw someone post that their RAK4631 and they say it lasts for 18 days on a single charge of a 3Ah battery. ๐Ÿ˜ณ Maybe I should make that two pairs of batteries instead of 2 4-packs. Because a theoritical battery capacity of 240 days (~8 months) is probably not the most effective use of my batteries. Heck, one 5Ah battery would probably suffice! The good news is that I can leave the case design alone and just rock two pairs.

Crowdhealth folks: what's the URL that let's me check the discounted prescription prices? I emailed the company asking buy they won't respond to me

I have a tenticle which can barely accept an M6 screw and it's 284MB. What am I even doing? #3DPrinting

I have a #3DModel of the #LoRa #radio #solar node that I've been working on for months. image At the top are the mounts for the DFRobot MPPT board with the RAK 19010 board just below it. The big empty space is for a battery pack (4x 26700s). Of course now that I'm posting this I realized that I want a second battery pack, and I should probably have holes for the solar to come in and antenna to go out. Oh and a short divider so the battery pack doesn't ram into the RAK in transit would be nice. But am I going to delete this draft and make it look like I did it perfectly the first time? Nope. Post your failures. Own it. Keep it real.

Just modified my canning jar holder #3dmodel - about 10% less material - 1h17m faster (now at 7h0m) - reduced number of supports required #FreeCAD #3DPrinting

#bitcoin folks, shill me a solution here. I want: 1. Ability to make a batch of payments easily (e.g. I give it a CSV of addresses & amounts, it makes all the payments) 2. Capital gains tracking (don't give me a hard about this, it's a requirement here. Full stop) 3. Easy for traditional accountants to use Self-custody preferred, not strictly required Lightning support is optional, but it'd be nice to have

I'm trying to be cool even though my favorite wallet may have just lost ~700K of my sats. Even if I can get the money, my confidence in the software has been shaken. ๐Ÿซค I'm going to sign off for a little while and chill out.

I connected a second #battery to my #solar node (one in the #RAK, one in the #MPPT board). I thought the second RAK would drain first, but that's completely backwards! From the RAK's perspective, it's always going to draw from the solar side, so it'll never use its own battery until the other one ia dead and it's dark out. The other interesting fact is the RAK battery went from almost no charge to 70% in a single day. Why? It's draining the other battery. Why? Again, as far as it is concerned, that isn't a second battery, it's a solar panel. All this means that of I ever see #meshtastic report a low battery, I know we are in real dangerous territory. That'd mean it drained one battery completely, which is not trending in the right direction! Experiments are fun ๐Ÿค“
