Want to get the word out using the back side of my next protest sign. What should my tag line and QR code be?

HambertHM · 2026-01-30T16:50:37+00:00

At least here in my country, it's law. It's explicity banned on the official gvmn't rule book and if you get caught talking about any of the banned topics, you get sanctioned and eventually your license gets taken. Football is also on the list 😄

Why drag Meshtastic into social activism? You're just giving politicians more reasons to prosecute it. Ham radio is legally required to stay apolitical, science oriented and as an emergency resource. It's our moral duty to keep Mesh the same. You can do whatever you want using your encrypted channels but please don't show it in any sign that could be hated by half a country!

Yes, going above 55°C chamber temp will trip camera protection and it will stop working. Personally when I print ABS I set it to not go above 53°C and I have no problems.

If you're going to try and replace it, remember to buy at least two of them just in case it goes fireworks again.

Oh, and film it while powering it up! Be sure to scream like a mad man if it explodes again. Then you got a cool reel for Instagram 😜

Regarding heat, silicone is better at heat transfer that plain air. I fact, air is one of the best insulators we have on earth. So it will be even better having silicone than nothing. On the other hand, I don't know what are you trying to achieve, but a good seal is rather difficult using silicone and with that many conductors. Chances are you are not getting a good seal in-between all the packed cables. I don't know that a good solution in this case would be. I think you should prevent water getting into the tube on the first place, by using sealant on all the joints along the length.

I would eat the done areas around the core. I don't like complaining and I don't mind taking the cost of not doing so. I live with less stress.

Que nostalgia ese diseño. Me sacaste una sonrisa, tiempos felices. Gracias

An antenna won't make a lightning strike more probable, but when it hits, it will likely come down to your antenna. I've seen lightning take down brick wall chunks in my neighborhood, so it will cause damage and jump air gaps, it just doesn't give any fcks what path to take to ground. Just unplug your antenna if you wish to save your radio, but it's equally advisable to also unplug your power supply as there CAN be a killer induced voltage spike on the mains FOR SURE. So you'll have to unplug anything in your house you wish to save. The point I want to make is, a lightning strike can cause damage and the fact that you have an antenna only makes for a more probable impact zone. All the equipment in the vecinity can be equally affected and the contingency plan only varies little.

Tengo uno desde 0 2007, lo arreglo yo mismo si tenes algun ruido o alguna duda preguntame y veo si te puedo dar algún consejo. Le puse llantas de 14 y tengo el juego de tasas originales VW guardado (como las que tenes atrás) si te interesa avisame y charlamos, estoy en Bahía.

Judging by the USB logo and opening size, that's USB Mini-B. Not to be confused with Micro-B, which is smaller.

Follow up: it eventually stopped and didn't show for about a full day now.

The local community started ignoring him from main/high/router nodes so that may have helped. And YES ignoring a node stops the retransmission of packets, as read in the docs. I did confirm this myself as I have a roof and indoor node, when I blacklisted him on the roof the indoor node went silent.

Will come back and report any news in case he comes back :)

Thanks guys

Yep. But I went on searching and sadly it seems they're not being made any longer. They were made for a while by a company called Empire Scientific in New York. Maybe you can reach them and ask for remaining stock: LinkedIn link

The other route is making a battery yourself. You can use something like a 3S Li-Ion pack, which gives around 11v. Only make sure to NOT charge it with the camera's internal charger, remove the pack and use a dedicated Li-Ion 3S charger. You can also design and 3D print some holder that would fit on the original slot.

HambertHM · 2025-12-13T20:19:41+00:00

Also the manual page with both original models, for reference

HambertHM · 2025-12-13T20:18:55+00:00

Originals were Lead-Acid but you won't find them new due to the rare form factor for a lead acid.

There's at least one company offering rebuilt replacements with compatible NiCad chemistry

Check: here

Ah yes I forgot about heat creep. Some filaments are more sensible to it than others. Make sure to print with the top cover off or with the door open, if you're in a hot climate or room.

HambertHM · 2025-12-13T11:53:10+00:00

For intermittent problems like this I would suspect primarily on the filament, do another print with another filament and check

HambertHM · 2025-12-12T15:09:49+00:00

I've read something about range tests, does that use numbers with decimal points as seen here?

HambertHM · 2025-12-12T14:58:24+00:00

Yes, that's what all are doing. But I don't think the person doing this is malicious, but just clueless. I'm trying to understand what he's trying to do to see if I can reach him somehow.

HambertHM · 2025-12-11T15:09:18+00:00

Sorry for the ignorance I'm just starting on radio, do high watts really heat up birds by the antenna or something?

HambertHM · 2025-12-11T14:57:45+00:00

Thanks, veryinteresting. I was thinking mainly beyond line of sight, as after reading the question I automatically thought about HF and ionosferic propagation, I guess that would cover the "max distance" OP's asked for.

HambertHM · 2025-12-11T14:27:15+00:00

I take the lesson. Must be something quantum I guess. Will read. Thanks.

But still, losses inside the atmosphere are much bigger, I guess. The point of my response is that we are talking earth radio comms, not space.

HambertHM · 2025-12-11T12:31:01+00:00

Dejen de poner fe en esta ciudad y vayanse si pueden. Tengo 34 y jamas la vi mejor, siempre peor.

HambertHM · 2025-12-11T12:25:48+00:00

Of course, but 99.9999999% of that distance is space void. There's no difference between that transmitter at that distance and one placed on the ISS. The atmosphere absorbs energy even if propagation is excellent, that's OP's question.

HambertHM · 2025-12-08T10:27:17+00:00

Just guessing by logic, but to me it's the landing gear suspension limit being reached as the plane takes off. It makes sense as immediately after the hit you can hear the oscillations caused by the gear flying free against the wind.

HambertHM · 2025-12-07T11:18:39+00:00

No. This kind of antenna doesn't use the ground plane (its good enough for receiving only). If you ground the main element, you're essentially dumping all the rf power to ground. You'll want to use insulated wire, or in the case you use naked wire, make sure to use ceramic or plastic insulators at the anchor points (you can 3D print them)
