I get that it isn’t the same but when all you have is a garbage version of a memory, I’m not sure or really matters whether the representation is the original garbage or something that makes you feel less regret over not having something better.

In my experience, the worse the photograph the better my memory of it. Probably because my mind is already used to filling in the blanks in the garbage version, so it’s constantly refreshing the memory in my mind to keep it vivid. YMMV obviously. I’m also not much of a shutterbug and prefer to commit moments to memory than try to fight with my phone to snap a photo I’ll probably never look at.

This appears to be part of the “Parents Decide Act”

Sure would be nice if parents would decide to parent their own kids instead of making it everyone else’s problem.

Looks promising, thanks. Gonna download and play around with it now.

You’d think the standard PDF viewers in Linux (Okular, etc) would at least show you alt text but nope. Seems like a huge omission.

Unfortunately, that seems to only work when exporting from a LibreOffice doc. What I’m having to deal with are PDFs generated by various staff already in PDF format.

I don’t use MQTT currently, but there’s several things you can do with it:

• Pass some messages as plaintext for use in, say, HomeAssistant
• Bridge meshes over the internet
• Send/receive ProtoBuf messages from an MQTT client to the Meshtastic node and the mesh
• Plugging in some of the mesh mapping programs to visualize the mesh

I tried setting up MQTT with HomeAssistant but couldn’t get messages to come in correctly. Most likely my own fault but I just never got back to it as I didn’t have a specific need in mind when I was setting it up.

Most of what I’ve dealt with were ESP32-based devices like the Heltec V3 (now V4) that have integrated LoRa radios. It should be possible to add on a SX1262 LoRa radio via SPI and flash Meshtastic firmware, but most people just start with a pre-built kit since they’re pretty inexpensive and have battery charging circuitry and everything already onboard (which you’d otherwise have to handle yourself with a vanilla ESP32).

I started with the Heltec V3, and the V4 improves several gripes I had with it. They’re easy to get started with, lots of case designs available, and generally good entry points.

SeeedStudio has a lot of pre-built options as well. My new daily driver is the SenseCap T1000e which is about the size of a few credit cards stacked together. Posted about it here: https://startrek.website/post/34105873

There’s two main flavors of Meshtastic devices: ESP32-based and nRF-based. The former are generally a little less expensive and have WiFi but are a lot more power hungry.

The nRF-based ones are more power efficient and can run longer from smaller batteries. The tradeoff is those only have Bluetooth and lack WiFi. I don’t really use WiFi with these, but it can be useful if you want to connect a node to MQTT.

Definitely one of the “throw it on the pile” projects for me, too, but I’m for sure throwing it on the top of the pile. Have had quite a few severe storm warnings this year already and this could be pretty useful. I was originally just looking for a way to forward NWS/EAS alerts to Meshtastic from the internet, but getting them direct over-the-air is even better.

Only complicating factor is I have to fashion or buy an antenna for ~150 Mhz since I don’t have any adapters that will fit the RTL-SDR (I’ve just used the little stock UHF TV antenna that came with it for ADS-B and other playing around).

AFAIK, yes, memory. There are a lot more packets than just text messages. Telemetry, node info, positions/waypoints, etc.

This is from memory and anecdotal, so take it with a grain of salt.

On firmwares below 2.7, I think it only stored the last-received message on the node itself. 2.7+ may store the latest message from up to a few different contacts, but not more than that (if even that). Either way, it’s not really meant to operate as a “mailbox” where you can retrieve the messages later; they basically need to go somewhere as they’re received.

There’s a store-and-forward mode that can be enabled, but it stores all messages for everyone and is more of an infrastructure node role. It also requires hardware that has PSRAM which the Heltec V3’s don’t have.

True, but I’ve had two grid-tie inverters, and both have had anti islanding protection and would not function when there is no utility power. Pretty much all grie-tie inverters have that protection.

I’m specifically referring to the interconnect agreement, though, which is where you have to jump through a bunch of hoops, fill out a bunch of forms, pay a fee, wait for the power company to come and inspect it, and get the utility provider’s blessing before you can hook in a grie-tie inverter and export even a fraction of a watt.

And you have to go through that process every time there’s a change to your system. e.g. If I start out with a 400 watt balcony solar kit, get that approved, and want to add another 400w kit, I would have to file new paperwork, pay another fee, wait for inspection, etc.

I’m all for reasonable safety measures, but the power company in my area is clearly doing all it can to pay lip service to “yes, we support balcony solar” while also making it as painful as possible for homeowners to actually implement it.

I’ve had to plan on a PV+battery+load sharing solution because my utility provider will fine the absolute crap out of you if you export any power without an interconnect agreement in place. I used to be able to stealth grid-tie with the old analog meters (I never produced more in a month than I used), but these new digital tattle-tale meters will rat you out instantly.

No thanks. Only the worst people / least deserving to live forever would be able to afford this.

No idea, just thought it was interesting and looked like an easy thing for a first time homebrewer. The guys in the video operate a honey farm, so I’m inclined to think they know what they’re doing (or at the very least don’t blink at wasting honey lol).

Did they train the model on YPTB or something? That’s so on brand it’s actually quite funny.

It is but it doesn’t federate.

Only if the USB Implementation Forum doesn’t get a chance to name it. Otherwise, it’d be something like DNA 3 2.0 Super Speed

Truth.

I just see those devices as mesh extenders waiting to happen lol.

I don’t even remember how I learned about Meshtastic. It was just one day I’d never heard of it and the next day I was obsessed and had multiple radios to play with. How I got there? Total mystery.
