Meshtastic – An open source, off-grid, decentralized, mesh network built to run on affordable, low-power devices.

Meshtastic is a project that enables you to use inexpensive LoRa radios as a long range off-grid communication platform in areas without existing or reliable communications infrastructure. This project is 100% community driven and open source!

Do you know The Things Network?

For a grassroots free network on open (ISM) frequencies, coordination and documentation is a bit more challenging - we are only just starting to map the new generation of gateways.
@dasyaITU is hosting and testing a number of gateways, reaching sweden, germany and a lot of the (baltic) sea.
Get in touch if you are interested or like to contribute.

Do you know The Things Network?
The idea is to build a free non-commercial low power network for ,
for communities, people and businesses to use.
Currently, it is made up out of approximately 20,000 volunteer gateways -
with the highest density around the project's origin, the Netherlands.

The low energy aspect is interesting - we dont need power-hungry to collect environmental data.

"Plants produce organic matter through photosynthesis, but only part of this matter is used for plant growth. The rest is excreted into the soil through the plant’s roots.

In the soil, bacteria around the roots break down this organic matter, releasing electrons as a waste product.

The technology developed by Plant-e harvests these electrons to power small electrical devices."

So let's talk about #lowpower computers?

I have several computers in my home right now that are always on. They are also pretty OP for the tasks they perform.

That's fine while I live in an area with abundant and cheap electricity, but if we are producing and storing our own power that becomes less of an okay thing.
