RE: OrderUp - Turning a Spoken Order Into a Signal the Kitchen Can Hear

Nice project. You are using the fact that reSpeaker can detect the direction the voice is coming from and using that for seat-1 or seat-2. That is very impressive. Any chance for wrong detection?

If you use a No IR filter camera, you can send the messages in infrared, so they remain undetectable to casual observers.

Very cool.

I have spent decades trying to eliminate EM for avionics systems.

If you want to have some additional fun, you can add some ferrite beads to the circuit and observe their effect.

Nice idea. Is the data rate to high to decode data perfectly? You are using an optical link. What about bends in the wire. Does it still reflect the light?

Nice project

Nice build with the Seeed studio reSpeaker.

Very nice post.

It looks like you had a lot of fun putting it all together and running the tests.

Nice overview for getting up and running with Meshtastic and nice use of the solar powered hat.

( If we spot you wearing a sombrero, we will know that you are scaling up [emoticon:c4563cd7d5574777a71c318021cbbcc8] )

Interesting that the d5a4 node is showing up as being 22 miles away but isn't showing any hops.

Is that because it just isn't being reported for that client or perhaps it is leveraging 'Zero-Cost Hops' via preferred relays ? Or perhaps on an airborne drone, so actually has line-of-sight.

It would be interesting to know how many nodes were being relied upon in typical deployment scenarios. Do you see the number of hops back to base logged when you are out for a stroll ?

One thing the system will likely be reliant upon in emergencies is for static relays to have back-up power in case of a local power outage.

Very detailed Project! Nice test of the Wio Tracker L1 as well.

Nice project Ralf.!

I think that Mechtastic is good for urban places where there are other nodes that can relay the traffic. Not for rurals.

Very nice! Cool application as well.
I have two Meshtastic nodes. One is powered all the time but I never think to look at my phone to see if anyone is chatting.

Hi [mention:a79c895a0bcf4008bedf3324d37dd0f5:e9ed411860ed4f2ba0265705b8793d05] , please remove and re-upload the images in your blog, some of them are broken. Looking forward to being able to see the full thing! Try using the insert > image, option rather than copying and pasting images, that's usually what causes the problem.

You can also insert videos in this way.

Thanks! It's definitely satisfying to bring these devices back to life rather than letting them turn into e-waste.

Kudos for keeping a nice device going beyond its manufacturer's enshittification.

But now for something completely different: the blue cabinet to the left of the weather station, is that a rack of little drawers to keep small components organized? If yes, please drop the manufacturer's name and model. I could use something like that.
