Should use PJON as a transport: https://github.com/gioblu/PJON

1) What happens to the waste? 2) How much energy is required to make the paste?

The PJON protocol: https://github.com/gioblu/PJON

You should try to run gemini over PJON https://github.com/gioblu/PJON that could really change the game.

I totally agree with the OP, check out the protocol I am working on since 2010: https://github.com/gioblu/PJON

PJON could help: https://github.com/gioblu/PJON/

Isn't the coherer https://en.wikipedia.org/wiki/Coherer the first memristor? If so it was invented in 1890.

> We need a decentralized web. For us, one option would be IPFS, which is starting to catch on. For the binaries themselves there’s already the option of downloading through torrents.

I agree with the OP Bitcoin should run over a network protocol like PJON https://github.com/gioblu/PJON and a private network infrastructure made by people.

The point is, if you switch just the protocol, and keep the same infrastructure nothing will change.

The Arduino Team may not be happy about this.

I have experimented a lot with memories, for now the most interesting path is to use just LEDs as 1 bit of dynamic memory.

1. Cover the LED so it cannot be hit by light 2. Charge it in reverse bias to write a 1 or do nothing to write a 0

inverting the polarity and reading the + you detect a voltage for up to 3-5 seconds depending on the diode if a 1 was written in earlier :)

You are right! So just misspelled :)

The word medium identifies a mean of communication. The commenter uses it to identify a mean of exchanging value. IMHO the word was both misused and misspelled.

Here in Italy (that is where the word was invented in the first place) that is considered a bad common mistake. Forgetting about the etymology or misusing a word is not what I would define as "evolution". We say multi-media, mass-media ecc. for a reason, for the same reason we don't say multi-mediums or mass-mediums.

The word medium comes from latin, its plural is "media", not "mediums".

Wood is a very good heat shield and was used by China at the start of their space program when composite material was beyond their manufacture abilities. What they will likely achieve is to preserve what is inside the wooden box during re-entry and rise the chances of hitting something and cause damage.

IMHO the privileged point of view is yours, we are not the only inhabitants of earth looking up to the sky in the night, many animals rely on it to navigate/migrate. Many humans still don't know what is the internet and enjoy to look at the sky for pleasure and necessity. For sure when someone thinks it is ok to change the earth's night sky, just to be able to work from home, avoid to go to the bank, to see cat videos, memes and fake news, is by definition a privileged lazy guy.

Incredible the most interesting find did not make it on the news media. A writing was found on top of the dog figure "Nicia cineade cacator" that translated means "Nicia (name) homosexual shitter", archaeologist presume that is a joke written by a client to underline the sexual orientation of the seller. Apparently, looks like in Rome was normal for people to joke about the sexual orientation of others.

I also see the deployment of those massive fleets of satellites in LEO to be suicidal. It makes access to space more complex and expensive. If for some reason few collide they could start a chain reaction that could destroy most LEO satellites now operational and preclude access to space https://en.wikipedia.org/wiki/Kessler_syndrome

>Aggressive space activities without adequate safeguards could significantly shorten the time between collisions and produce an intolerable hazard to future spacecraft. Some of the most environmentally dangerous activities in space include large constellations such as those initially proposed by the Strategic Defense Initiative in the mid-1980s, large structures such as those considered in the late-1970s for building solar power stations in Earth orbit, and anti-satellite warfare using systems tested by the USSR, the US, and China over the past 30 years. Such aggressive activities could set up a situation where a single satellite failure could lead to cascading failures of many satellites in a period much shorter than years.

Really cool thanks for the link. I have experimented a lot with the OOK modulation and open-air laser wireless communication. It can be done just using visible light LEDs as detectors and small laser diodes, they just need to be of the same color. A free-space optical link can be built in minutes, see https://github.com/gioblu/PJON/tree/master/src/strategies/An...

It should use PJON for communication: https://github.com/gioblu/PJON

In my opinion your comment is clearly out of place.

This post was in the first page thanks to dang, who decided to let me make a repost, after this comment generated a lot of interest: https://news.ycombinator.com/item?id=23589798 now 6 months ago

and this post I created immediately after got huge interest although being only visible in the "show" first page because it was "flagged": https://news.ycombinator.com/item?id=23591953

and that is just the standard policy of HN.

But you could have just discovered most by yourself just checking my account info, instead it looks you are prone to see conspiracy behind everything.

Many of you accused some users of our community to be fake and guilty of trying to influence the narrative, they did everything to prove their feedback was sincere, you gave them the benefit of the doubt.

Another user postulated the same could have happened in the opposite direction (trolls trying to discredit this submission), I told him he might have a point, you label me as a conspiracy theorist.

That's for sure fair.

>It's almost as if "somebody" doesn't want projects like this one to succeed. Who would benefit if PJON and others like it didn't exist? Who would benefit if users instead had no other option but to pay a for-profit company for the hardware, software, and (of course!) the recurring monthly subscription fee instead of just doing it themselves? Hmm... (see how easy that is)?

jlgaddis, probably there could not have been a better way to describe the situation.

Thank you for your feedback, happy to know it helps :)

No worries, for sure the SoftwareBitBang implementation is not designed to stream digital audio or video at high speed but it is handy for many to move few bytes from sensors in a local network that can be built very quickly and at a low cost.

Have a nice Christmas :)

Here you can find the implementation of PJDL used by Jack Anderson to determine the maximum range:

https://github.com/gioblu/PJON/tree/master/src/strategies/So...

All devices listed in the compatibility section are able to communicate over a twisted pair with no additional hardware, as Fred well noted, you just need one wire and connect directly the IO pins. And up to 255 devices can share the same twisted pair.

As you can read in Video Camera Control Jack just used two arduinos, 2km of wiring within his university's network and a couple of pull-down resistors. The protocol works even when the human body is used as a conductor as shows the gif present in the article.

On social compare someone made this: https://socialcompare.com/en/comparison/comparison-of-networ...

I think the comparison between PJON and LIN there is revealing. As you can see LIN handles up to 16 devices, it is master-slave and has a range of 40, with a complex front-end at a relatively high voltage.

PJON is free for use, it is all open-source. We do sell products to fund the development of the project.

Yes Jack is right, another massive advantage is that with PJDL devices can arbitrarily transmit data safely, enabling new ways of building things, for example sensors and actuators can communicate directly with each other without a master in the middle.

Ciao jlgaddis Jack in Video Camera Control used PJON over PJDL which is a wired data link that needs only ground and a data cable to connect up to 255 devices, cables can be up to 2km long at the slowest baudrate (1.97kB/s - 15808Bd). PJDL in few words is a sort of open 1-Wire with a longer range, support for more devices and a stronger immunity to noise. See: https://github.com/gioblu/PJON/blob/master/src/strategies/So...

The core of the community uses PJON over PJDL in home automation systems, irrigation systems, feeding systems ecc. Soon Mysensors will include PJON over PJDL in their list of supported transports. PJON works also over TCP, UDP, MQTT, ESPNOW, LoRa ecc. so generally a router is built and programmed to run 2 instances of PJON for example PJDL and MQTT, to then route data to and from a process running on a real-time operative system

See: https://github.com/gioblu/PJON/blob/master/examples/routing/...

which can also run PJON thanks to the wide support of the implementation.

See: https://github.com/gioblu/PJON/wiki

Looks to be handy for many to connect devices, even on different media.

Although many also use PJON to implement mesh or peer-to-peer networks, there is a group in Australia building such a network using PJON over LoRa.

I must say I hope we will be able to start building a private network infrastructure with it, that would be awesome.

Companies and institutions are also implementing PJON within their products and services. AD24, a Czech company, recently created a mesh network over PJON to connect advertising monitors around the city of Prague. It looks there are also few companies in Germany which use PJON to create real world automation systems.

Recently contacted by the Universitat Politècnica de València (UPV) to support the development of a PJON network of temperature and humidity sensors to monitor the vault of the Cathedral of Valencia and avoid its decay, I hope this will end up done, it would be really rewarding.
