Ronja - D.I.Y. wireless communications

AI Thread Summary
Ronja is a free technology initiative focused on creating reliable optical data links, achieving a communication range of 1.4 km and a speed of 10 Mbps full duplex. The project offers detailed plans for various wireless network devices, including parts lists, instructions, and diagrams, all licensed under the GNU Free Documentation License. Key limitations include the necessity for a direct line-of-sight for operation and reduced functionality in dense fog. Despite these challenges, the project is viewed positively, with suggestions for enhancing reliability through multiple optical links for redundancy and incorporating backup WiFi and wired networks to mitigate potential issues like obstruction and interference.

Ronja is a free technology project for reliable optical data links with a current range of 1.4km and a communication speed of 10Mbps full duplex.

On their website, they provide plans for a few different models of a wireless network device. The plans include parts list, instructions, pictures/diagrams etc., and are licensed under the GNU Free Documentaton License.

Limitations of the device are that it requires a direct line-of-sight to operate, and it's functionality will be severely impaired in dense fog.

Nonetheless, I think the project is excellent, and I really agree with a lot of their philosophy (but maybe we shouldn't go into that).

What do you think?

It's pretty interesting. It has some obvious flaws but these can be compensated. For example there could be multiple optical links, for redundancy. There could also be some available WiFi and wired networks to serve as backups.

Thread 'Urgent: Physically repair - or bypass - power button on Asus laptop'

Asus Vivobook S14 flip. The power button is wrecked. Unable to turn it on AT ALL. We can get into how and why it got wrecked later, but suffice to say a kitchen knife was involved: These buttons do want to NOT come off, not like other lappies, where they can snap in and out. And they sure don't go back on. So, in the absence of a longer-term solution that might involve a replacement, is there any way I can activate the power button, like with a paperclip or wire or something? It looks...
