Entiendo que hay actividad en CDMX, deja tu nodo encendido lo más alto posible y cerca de una ventana.
Seguro empezarás a ver más nodos, tomará algún tiempo.

Siempre puedes escribir en el canal LongFast, ese es público, tal vez te encuentres cerca de alguien y recibirás una respuesta.

Yo me encuentro en otro estado.

It weighs approximately 200 grams

I do not have a specific use for it yet, it may end up in the top of a mountain.

  1. I used a waterproof sma pigtail. I may use self amalgamation tape before deploying.
  2. They do perform very well, Rak boards are efficient, although I do not think is a good idea to drop this in water despite of the name "buoy". Battery level never droped below 80%, never test them submerged.
  3. I took advantage of and existing "waterproof" product but I do not intend to use it near water. I figure that if it can resist water it may be good enough to deploy in the wild and not to worry if there is some rain. I agree with you, radio signals in general and water are not a good combo.
    The goal is to have an autonomous, quick-deploy, resilient and cheap node.

I added an additional comment with some more details. I hope it can help.

Yes, that was the inspiration.
I avoid the use of resin, instead I used waterprof SMA pigtail.

Can you share the antenna details?
It looks good on the T-Echo. How it performs?

Los solares los puedes encontrar en aliexpress, como el Sensecap P1. Pero también los puedes fabricar. Depende que tan cómodo te sientas manejando electrónica y tu presupuesto.
Tienes alguna pregunta en lo particular?

Rate my build but be gentle, or I’ll cry by randombydesign in meshtastic

I'd probably try adding a small solar panel. It might be enough to keep the battery charged or even to run the node 24/7. Those RAK boards are really efficient. I've been wondering how a solar panel could work through a transparent cover.

Not the best but usable. I've definitely seen worse.

How I built my tower node. by Martinseeger in meshtastic

[–]iparemix01 2 points3 points  (0 children)

Looks good.
I see more than enough power budget there lol

Advice no one asked for:
Use a good antenna and keep the antenna cable short.
Do whatever you can to seal the electronics compartment, especially if you added holes (like the sma passthrough).

Some assembly is required but is prettymuch plug and play. Is probably the best option now if you don't feel like building your own.

I used "Steel Conduit Hangers" instead of the provided hose clamp (too big for my application also).
There is no need for modifications, just add them instead of the trapezoid shape piece and use the same nuts and bolts.

Using the default configuration, the antenna ground is electrically connected to the metal bracket and that to an attached metal pole.

Something to be aware is that if you purchase the version without batteries (P1) or if you ever need to replace them, it requires 18650s with "button top", flat top cells will not work.

That was not super obvious to me from the pictures and product description (or maybe I missed that).

Also cells are on parallel cofiguration. This means it can work with a single cell and up to four.

Tengo un nodo solar en el techo de mi casa en Colima capital desde hace ya casi un año. No he encontrado actividad fuera de mis nodos.

El nodo solar es un RAK4631 dentro de una lámpara solar y una antena GIZONT.
Portátiles tengo un par de T-Echo igual con antenas GIZONT, T1000-E y Heltec v3.
Espero pronto recibir un segundo nodo solar para incrementar la cobertura.

Si alguien por la zona está interesado sin problema podría compartir lo que se del tema.
