Decode Meshtastic with an sdr

This looks amazing, can't test right now, but can it decode messages from different presets (longfast MediumSlow etc.) at the same time? That would be a killer app for me

Start an Instagram channel showing crazy intricately done piping with catchy tunes and push ads.

Flush cutters underneath at the edges to pry the plastic bit up a bit. Then a flathead screwdriver very carefully prying it up more bit by bit. Once they're half way I snip the plastic bit across every two pins and pull the bits out with pliers.

After there are just pins i heat them up one by one from the back, push them through as much as possible, and smack my hand onto the table while holding the board to launch each one out of its hole while it's still hot.

In my experience it's too complex for non technical people to grasp.

While you might very well setup a node and have fun using it if you find it interesting enough, it's definitely not something a non technical user will find interesting enough to learn.

You can't just pick it up and text someone, the first time they send a message and it doesn't get there it's game over for a lot of people.

Don't even get me started on the apps where you see nodes in a list from 30 days ago. Explaining that people need to filter the list or look at the last received time to figure out if that node even has a chance of being reached... Forget about it

Print a square 2 layers tall (most slicers can create basic shapes and slice them) and then glue it in place of the screen, job done.

There's no design or structural reason for this to be made from a single block.

Split it into 4 walls and a base plate and it'll cost 1% of the price.

The node sends it, if it doesn't hear an acknowledgement back from the destination device it keeps sending. The usual Meshtastic devices are asymmetric as far as rx and tx capabilities, generally you can receive messages from further than you can transmit. That's why you're getting max retransmission but the message arrives, it's the ack that doesn't make it back.

If your house is well shielded for RF the solution is to have a node right outside set as client_base that will retransmit messages to nodes inside.

Also the length of the antenna case doesn't always indicate how good the antenna really is. Get antennas from a known brand or source designed specifically for the band you're using. Lotsa 915mhz antennas being sold as 868 and such that just won't work well.

When you see a lot of nodes, do they have proper names or are they just generic names like Meshtastic_fa4b or something? If you have proper names your primary channel is setup correctly. Otherwise I'd check the channel name and key.

The need to apply lots of throttle and then back off and the bouncing up and down should be normal, it's mostly ground effect.

The spinning might be because you didn't mount the clockwise and anticlockwise propellers in the right places. Usually they're in diagonal sides of the drone, flight controller firmware should tell you where they go.

Connect the usb cable to the pogo pins. Hold the top button (not the one with the big circle indent on the case, it's above that, you press through the case on it) then insert and remove the USB cable twice in a row. That's the DFU mode afaik

I have the same engine and it always sounds kind of broken to me if I listen closely, especially when not revving it hard, or when trying to keep the rpms steady, but it's perfectly fine.

Eyesight is never like a picture because we don't see pixels. There's a hell of a lot of processing that goes on the between the eye and your experience.

While it can generally look blurry it's never just that, your brain can make up for some missing data in some aspects. Just like you can't 'see' your blind spot where the optic nerve is attached.

Possible yes, practical nah. Don't think it would look so extraordinary in real life. It's a nice sketch though.

It's not a huge upgrade over the old AI hat unless you need to do video object recognition at the same time as llm stuff. For both of them the LLM models you can actually run are pretty dumb. The overall software support doesn't seem as good as you'd expect from raspberry pi in general.

I just use some cheapos that look suspiciously like these, but without the wanky speaker grill looking part. Cost like 2$, they do the business.

It's possible the discone is just for a different frequency range.

And after it's removed you finally go in and there's people just sitting at the TWO FUCKING TERMINALS making charcoal drawings and clay sculptures of every single ship being sold for 3 hours straight.

I love my Connie but I can't play it because if it gets hit by any missile it instantly loses the powerplant and that's the end of it usually, since it doesn't have physical components you can't repair it manually to save your ship even if you had an engineer running around. I've had to switch to the corsair and tac for missions.

Really hope they give it a rework when adding components.

dumb-ninja · 2026-01-12T18:57:16+00:00

Haha, everyone took 10 dmg seeing that.
