#LoRA is a popular technique for fine-tuning Large Language Models (#LLMs) on the cheap. But there has been an explosion of new parameter-efficient fine-tuning techniques, Martin Görner dives into LoRA alternatives.

An interesting aspect of Swarm is, that their modems use #LORA for communication with the satellites. So it was no surprise to find a Semtech SX1278 radio SoC in this teardown.

Jag svepte en stark kopp kaffe.
Slog till på två LilyGO T-Echo.
En till mig, en till min granne.
Nu är jag otroligt förväntansfull.
För frågan är: bor vi just på gränsen till att kunna kommunicera med de andra noderna i Göteborg. Eller är vi den förfärliga radioskuggan jag förfarar!?
I updated my #LoRa #APRS logging blog post. Thanks for @mike_k for reminding me about the https://lora.ham-radio-op.net/ site!
Nu har jag lagt hela kvällem till att läsa på om #LoRa och #meshtastic
Om någon har tips på var jag kan köpa ett bra starter-kit som inte är för dyrt och som gärna finns inom EU skulle jag bli otroligt glad!
In my adventures with Meshtastic, I acquired a Sensecap Tracker (T1000-E) that I carry with me.
In the DIY loop community of diabetes, many people use an old Medtronic insulin pump that communicates over the 915MHz band, similar to LoRa. This requires using a bridge device such as RileyLink, OrangeLink, EmmaLink, and maybe others.
I think these are all closed source though. Someone made an open source firmware called GNARL which runs on earlier LoRa hardware, though, proving this could work.
It made me realize, among all the devices these diabetics have access to for their bridge, none of them are well designed nor well suited for carrying.
But the Sensecap Tracker is.
I just wish I had the knowledge to build up a firmware for it. The core platform isn’t the same as what GNARL is built for.
Es hat ja “ein wenig gedauert”, aber nun konnte ich alles in einem Gehäuse unterbringen.
Der Umzug von einem “Raspberry Pi 5” zu einem “Raspberry 2 Zero W” war, bis auf das Übertragen des Encryption Keys, auch nicht zu schwer.
Aber da konnte mir Mark den richtigen Hinweis geben.
(Bildbeschreibung: Ein Montagegehäuse mit einem darin verbauten "Raspberry Pi Zero 2 WH", einem "Heletc V3" und einem "SparkFun QwiicBus - EndPoint" für die Übertragung der "BME280" Sensordaten über ein LAN-Kabel.)
Ich habe soeben meine Sideband Installationen auf die Release 1.5.0, auf allen Geräten (Linux, Raspberry, Android), ohne Probleme aktualisiert 
Again, news about my #meshtastic #lora #cavityfilter builds
Last time there was the unwanted resonance a bit below the target frequency.
I got the thing back to my bench, hooked up the vna again, and opened the housing, and got two additional wires inside, and this cured the problem.
To see if a can replicate this, i made a second filter, all the same like this one.
With the additional wires at the same places too.
To make it more easy for me to calibrate this thing, i added setscrews to all 3 elements this time.
To my surprise 
this time the unwanted second resonance effect was there again, but this time on the higher side of the target frequency. This time i cant get it off.
I see now, cant replicate the working one reliable.
I assume the long cavity comes to close to 1/4 weavelength and get unstable.
I dont know for sure. RF is pure voodoo.
So lets see to get further, new folded cavity design, get the resonator elements count 1 level up to 4.
Entrenar mi propio #lora no funciono muy bien :( #dreambooth
corre en la terminal, pero no tiene efecto dentro de #krita
Idea for this PR is to add a network bridge mode for repeaters.
This will let you take multiple LoRa radios, setup meshcore repeater firmware and listen on any number of channels or with different antenna setups and bridge the routing across those different channels with a shared Wifi link(the two dotted white boxes).
I've tested it for a few days and it's pretty amazing to see meshcore automatically finding bridged routes.
Writing my first meshcore PR 
It's still a work-in progress, but having a lot of fun learning this code base!
Big News! #Semtech announced their 4th gen #LoRa chip, and they specifically mentioned #meshtastic! 
It’s truly exciting to be recognized at this level! We can’t wait to get hardware that supports this chip.

@tomjennings @Mark @phanuel @goldfishlaser Using #reticulum in #lora only #mesh using #meshchat application. It is beyond fantastic. No issues. Excellent delivery confirmation. Sends #images & #sound. When on the move with #rnode it resends messages, that failed due to no radio contact being available at the time of send, & sends them automatically later when in lora radio contact. Even re-sends chunks of images in batches as & when in lora contact again. Fab! Info: https://loramesh.org
We know we’re biased, but this video is phenomenal! 
Oh, and the good news? It’s no longer just a pre-alpha preview. We’ve elevated it to Alpha and it’s available in the flasher with no code needed.
Watch now
