Welp. Looks like I know the next thing I need to buy.

[utopicwork]

A big part of the drive for PierMesh is that I think based on Meshtastics ability to run on low power low cost boards that can be managed via a cellphone would make them helpful in disaster situations and particularly what Palestinians are going through right now. I've been trying to reach out to anyone in tech who is Palestinian/helping Palestinians who could spare some time to let me know if the efficacy of using LoRa (long range low power radio networking that can connect over kilometers) is worth trying to get some boards in that are preconfigured and encrypted. I have a lot more details I can provide and if you want to do some preliminary research yourself Meshtastics website is a good place to start:

What PierMesh would provide on top of this in its current state is multilingual support and currently I'm working on end to end encryption but even without that I think this technology could be very useful.

Thank your for your time

heyo! can you offer any recommendations for an ai image generator that can generate some pretty whacky geometrical stuff? I made this image as a sort of mockup, where it was generated using different patterns from different ai, and I cleaned them up and overlaid some that looked good on top of each other before some minute cleanup work and mesh manipulation, but it doesn't exactly mimic the sorta vibe for a "mesh-holding-organs-but-initially-all-you-see-is-beautiful-colors-before-the-horror-sets-in" that I was hoping for (also my computer bricked and I only have a low quality backup of it that I posted to discord :( , so any options that might work on my mom's work laptop would be doubly appreciated but totally can wait until I get enough money to get a new pc)

(also, thank you for fighting hard on the ableism with ai art. it makes me sad since this sorta stuff can be really cool and open up allowing people to make more aspects and larger projects of their visions without having to override anybody else's by focusing on their vision, on top of making it generally more approachable! it's sad since I totally get the fear that people have about this stuff being used to replace artists, but I just wish folks would realize that the problem is capitalism, not disabled people or people who dream but don't have time/money to practice every form of art "the correct way." but I can't blame them, because they are artisans, and artisan class interests are always in opposing the penetration of larger capital within their trades, since it usually means a devaluation of their labor, but whatever this was supposed to just be a thank you but I can never stop writing smh)

generally speaking i would recommend midjourney for most things nowadays if you're comfortable spending money just because --sref (style reference) is Just That Good. if you have enough examples of the thing you want to feed in its almost like making your own LORA but way less labor intensive.

What is the difference between the LoRaWAN wireless module and LoRa gateway wireless transmission technology?

Many individuals find it challenging to differentiate between the LoRaWAN wireless module and LoRa gateway wireless transmission technology, as well as their applications within the realm of IoT.

LoRaWAN specifically pertains to the networking protocol found within the MAC (Media Access Control) layer. In contrast, LoRa serves as a protocol within the physical layer. Although current LoRaWAN networking implementations utilize LoRa as the physical layer, it's worth noting that the LoRaWAN protocol also allows for the use of GFSK (Gaussian Frequency-Shift Keying) as the physical layer in specific frequency bands. From a network layering perspective, LoRaWAN can adopt various physical layer protocols, just as LoRa can serve as the physical layer for other networking technologies.

LoRa, as a technology, falls under the category of LPWAN (Low-Power Wide-Area Network) communication technologies. It represents an ultra-long-distance wireless transmission method based on spread spectrum technology, pioneered and promoted by Semtech in the United States. This approach revolutionizes the previous trade-off between transmission distance and power consumption, offering users a straightforward system capable of achieving extended range, prolonged battery life, and increased capacity. Consequently, it expands the capabilities of sensor networks. Currently, LoRa predominantly operates within free frequency bands globally, including 433/868/915MHz, among others.

On the other hand, LoRaWAN wireless communication stands as an open standard defining the communication protocol for LPWAN technology based on LoRa chips. LoRaWAN defines the Media Access Control (MAC) layer at the data link level and is overseen by the LoRa Alliance. It's crucial to distinguish between LoRa and LoRaWAN because companies like Link Labs utilize a proprietary MAC layer in conjunction with LoRa chips to create more advanced hybrid designs, such as Link Labs' Symphony Link.

LoRaWAN typically employs a star or star-to-star topology, which is generally considered superior to mesh networks due to advantages such as conserving battery power and extending communication range. In a star topology, messages are relayed to a central server through gateways, and each end node can transmit data to multiple gateways. These gateways then forward the data to the web server, where tasks like redundancy detection, security checks, and message scheduling are executed.

In summary, LoRa encompasses solely the link layer protocol, making it suitable for point-to-point (P2P) communication between nodes. In contrast, LoRaWAN includes the network layer, allowing data to be sent to any base station connected to a cloud platform. By connecting the appropriate antenna to its socket, the LoRaWAN module can operate at different frequencies, offering versatility in its applications.
