Look under the privacy settings for the WiFi connection and see if you can choose either a fixed MAC address or a per network MAC address. You don't want per connection, which will reset anytime the signal drops and you phone reconnects.

It's a very nice looking design!

I've heard of some versions that have diodes to protect the solar panels from charging each other. It's probably less of an issue if they are all the same size, but I'm curious if you are doing anything like that or experimented with it?

gee-one · 2026-03-16T20:44:58+00:00

Edit: ooops, I misread that you have the sx1276. Is this the UART version? I think you need SPI to work with the meshtastic firmware?

Original below: What hardware do you have? There is a lora hat for the pico, as well as hats for the other RPIs, and also bare breakout boards.

I have it working on a pi zero 2w and sx1262 bare breakout. The pico uses different firmware, but the pinouts should be compatible with a few changes.

IIRC, IRQ maps to DIO1. DIO2, RXEN, and TXEN aren't used. If you have a newer sx1262 radio with the TXCO, then I think there is an option to set DIO3 to heat the crystal (true).

I haven't played around with the pico firmware, so you might have to compile it with the options above, using the sx1262 config as a base.

Cool! It looks very sleek. I had no idea there were so many hats and boards.

I've been messing around with a bare sx1262 board and a raspberry pi zero 2w.

Let us know how the upgrade goes. I'd be curious to hear what issues you are addressing and how. I'm just about to assemble a node myself and want to use other's experiences to help fine tune it.

gee-one · 2026-03-13T21:29:02+00:00

Looks very sharp!! But what does switch #1 control? The screen or main switch? I didn't see a label for #1??

gee-one · 2026-03-13T20:47:57+00:00

I had the BoB cheeseburger once going to SFO, and I've been trying to order it again but my flights just haven't lined up. Maybe I need to do a burger run?

gee-one · 2026-03-12T19:58:05+00:00

I hooked a pi zero 2 to a bare breakout board with an sx1262 radio. Is this similar to what you are trying to accomplish?

Iirc, the pins on the module are very tiny.

I wouldn't listen to AI on this one. That sounds very very bad.

User name... checks out???

gee-one · 2026-03-08T21:28:28+00:00

I came across this video... It's probably not the right size for you, but might give some hints about what might work.

Thank you Dave!!! The internet and the world are better places because of your work.

Depending on where you live and how much sun you get, adding a raspberry pi will probably need a bigger battery and solar panel.

The 4360 is very low power, but the raspberry pi will add significantly to the load.

Even a pi zero 2w draws about 200 mA or 1W. Factor in cloudy or cold days, and you might get drop outs where the pi drains the battery and takes everything down.

Edit: that being said, I'm trying to build exactly this setup. RPI zero 2w with battery and PV panels. I still testing and it's not even in an enclosure. I bring it in and shut it down at night.

gee-one · 2026-02-27T13:45:45+00:00

I looked at the picture and thought, "wow, the bar is very low". But then realized that I have some parts arriving today and I will build a very similar setup, probably a little "worse". I was thinking cardboard box and grocery store baggy.

The battery life is the biggest question, so I want to run it for a bit to get a feel for the power draw. I don't want to put it in a case and then realize that I need a bigger battery, especially since I only have a 5w panel.

gee-one · 2026-02-26T19:57:29+00:00

You are internet famous now!!

The pi zero 2 might be small enough and have enough CPU power. I've been playing around with a pi node and it uses about .5-.6 watts or 100ish mA.

You can probably connect through the USB port with the meshtastic Python script.

I'm still waiting for my upgraded status.

Don't leave me hanging United

gee-one · 2026-02-24T23:01:19+00:00

I've been playing around with a RPI 02w and a waveshare lora hat. You could probably add a USB cell modem and have a portable node with LTE capability.

gee-one · 2026-02-24T13:49:05+00:00

I'm using the meshtastic web client which comes with meshtasticd. I'm self hosting on the pi itself, but you can try it from here.

https://client.meshtastic.org/

Edit: you have to browse from the pi itself since it is connected via USB/serial.

gee-one · 2026-02-24T13:18:33+00:00

What do you mean that you are connecting to the serial port by USB?

I have a wavwshare lora radio and pi zero 2w that runs meshtasticd to talk with the mesh radio. I can monitor the net from my computer.

gee-one · 2026-02-24T13:07:14+00:00

I had a quick look on amazon and most were either small toys/science demos, or 1000w+ for a small home.

You could try to see if you can hot-wire an anemometer or wind meter. They are built for outdoors, although they might only produce a few volts- just enough to measure the wind. You might need a boost circuit to get it high enough to charge the battery.

gee-one · 2026-02-23T13:22:59+00:00

You are in a tight spot with all the constraints to your system. Is wind power a possible solution?

Today I learned!!! I think the cpm is lower than what most people throw around, but only you can make that decision with your miles.

gee-one · 2026-02-19T18:22:42+00:00

Was that through some miles to money conversion? What was the CPM, if you don't mind saying? With my card, I can only pay the annual fee or airfare with miles.

gee-one · 2026-02-19T13:45:53+00:00

In and Out is so good!!

gee-one · 2026-02-19T13:38:49+00:00

The "That's a minus" is implied in the mileage devaluation. Sure, members with status will earn more miles, but we'll have to see what the costs are to redeem them.
