    At this point, I’ve found a carrier that does 10GB for $17 a SIM (and I could probably get away with less data for cheaper), and I’d be fine with that. I have several rPis that act as hubs taking in LoRa data from things like solar pumps, water bowls and bins, but backhauling to the central server over LoRa is a pain, and we don’t have LoS to all of them so using radio bridges is spotty. Some sites are 10km away over hills. And moving everything to MQTT would make my life easier than my custom BS programming that has devices talking to each other directly.

    We don’t generally have issues with phones and where I do, I can probably put up an antenna if the dongle has an external port, or I’m willing to spend extra $$ for an uplink with external. I currently have a Microhard LTE-CAT4 that I use on one remote site that seems to get good reception, but that unit is pretty pricy and I have to fart around with network cables and power when I could just be plugging in a USB dongle.

    I see a lot of cheap ones on Amazon, but I was hoping someone had a common Linux specific model they know works, because most of those look pretty janky.


















  • I’ve built several printers from the original RepRap to a Wilson II and a Deltabot. Some of those plans are probably getting on in age. There was a time you couldn’t buy a printer for the cost of building a reprap; those days are long gone. An Ender or similiar are so cheap and good now, it’s hard to build one of similiar quality. But if you’re just looking for a project, fill your boots.
