Update: my Heltec experiments are still a major failure despite the endless patience and expert guidance of @stereo (my mesh guru)... BUT! My family is maybe starting to take me seriously?!?

Major pivot from yesterday... looking at me like: "what are you doing weirdo?"

to today:

Them: "Is anybody else around here using it?"

Me: "Yes, let me show you on the map!"

Them: "Wow, impressive!"

Step by step 😅

Update no.3: my #MeshCore Bluetooth companion is picking up my Meshcore Repeater - YAY 🥳

We had to leave Paris in a hurry last month because of the brutal heatwave so I forgot the cases there. But here in Italy I have an endless supply of LEGO, so I built a custom housing for my Heltec v3 repeater, its battery and antenna. I really like it 🥰

that would lovely with a green or red antenna, and then some Star Wars Lego....

I still think, at some point, I need to get into the meshcore stuff....

Ask your little one 😁 !

I suspect she was involved in the design of the first one.

wihihi, got a bit simpler setup (first iteration using a tire to fix LoRA antenna in position and second one... just a cube with some fixtures for bigger antenna).

Btw, also Heltec V3. Made into easily backpackable contraption.

that is an awesome case!

One of the best things I did was to get an antenna that's tuned well for the frequency (I think you're on 868MHz there?) The stub antennas sometimes don't do very well.

Improving your repeater antenna would give you a better range, but there's nothing better than height!

#MeshCore update no.4: I'm now receiving messages from my Fedi friend @stereo who is 380km away across the Alps 🗻

I'd like to think my #LEGO stand proved to be a great good luck charm.

Ralf recommended I upgrade my antennas, so hopefully I'll be able to send out messages too... stay tuned!

@stereo does it exist a world wide map of those (to see if it's even interesting to look about it)

but congrat either way :)

📻 Adventures in #MeshCore communications - part 6 📡

My teacher @stereo recommended I get more powerful antennas - price: 9 Euros for 2.

They are slightly longer than my hand… and miraculously I went from receiving signals in Lombardy (my region) to reaching repeaters as far away as Sardinia and Rome!!!

How? It feels like magic 🤯

@stereo yes, antenna size matters......

Fun fact, in the math describing Synthetic Aperture Radar imaging, the formula that shows how fine a resolution you can resolve, the distance to target cancels itself out. No matter how far you are from the target, the resolution is determined solely by the antenna size.

Spy satellites in ultra high orbits get pictures just as sharp as spy planes only a couple thousand feet aloft.

@stereo sadly in my case the most close other one is 120 KM (~74 miles) from me.

So unless i build many of them i trow outside xD
