tnx… I’m a selfdescribed ‘ADHD electronic junk’ … but with a reason.
first I don’t have a day job and second I have had a stroke in 2002… a serious one, that damaged something.
so now I hear 24/7 ‘noise’ in my head… tweaking and electronics was my job when I was young so I picked that up again and discovered that when I.m programming/soldering I pay less attention to that noise.
I understand that for someone with little freetime, I must look like I am day and night at my workbench
Also I really hope that other TTN’ers show what they are doing here… see it as a kind of ‘electronic’ pub, this is not my ‘private’ topic
And the reason that I always post pictures is that I like that myself on other forums … makes topic more interesting imho.
You should be on the TTN payroll!
Bouts of mild tinitis myself but intermittent and not a life changer. How coincidental I have a deep vein clot and some embolism in my lungs. No stroke, just a big scare!. No reason as I am a competitive swimmer and (for fun) triathlete, a mystery.
Hopefully not related to 60:40 solder and flux fumes!

just now we have 30.000 lorawan frames transmitted on a single AA battery without missing one.
that says something about the quality of the TTN backend (and the rocketscream node ) and off course
the stability of MyDevices Cayenne.
big thank you factorylab for transporting the bulk of these packets.
Hi @BoRRoZ, no need for any kind of excuses from you! The viewing numbers for “your” workbench topic prove that.
Like @GryKyo, I also suffer from tinnitus. 40 years ago army training and exercising as artillery gun-crew has left me with continuous screeching that blots out all hearing from about 900Hz to about 1.3kHz. Most of the gun-crew men were completely deaf.
Like @BoRRoZ I use immersive engineering work to distract me from the noise.
Please continue with the good work on the workbench topic!
a few weeks ago I stumbled on eBay on these ’ range extenders ’
They are used to extend the range when controlling a drone. basically just a reflector…
So I thought, when I mount one on a circulair little platform that can rotate with the help of a little stepper motor, and in the middle stationairy a ‘normal’ rubberduck on 868 mhz, I can influence the 'beam / direction a bit by rotating the platform by controlling the stepper.
Imagine this antenna is following your lorawan tracker (it calculates the direction from the coordinates it receives and its own coordinates)
on a little screen you see direction, distance and …
maybe its not working at all, but I’ll give it a try… expect the 'range extenders ’ next week
@BoRRoZ fall in love with wires when he was young, he’s always prototyping with wires soldered everywhere even when using ESP32, for me, you know, it’s LED, everyone has to live with own daemon
Dustcollector: “Gathering dust” is an English saying which means that you are going to put it on a shelve and not use it, so it will only collect dust.
While your comparison will probably not be far off, a true comparison can only be made under identical conditions. You are currently using two different versions of the BSFrance LoRa32U4 board, the new one using an IPEX connector on the bottom, while the older one with a cable soldered directly to the RFM95 module.
Also, the exact same antenna (and position) should be used for both modules.
The best comparison i.m.o. would be with adapter boards like the HopeRF RFM95W adapter with SMA connector where the antennas can be mounted directly to the board.
It would also be nice to use a proper 868MHz dipole antenna (like those 19,5cm whips) for the comparison as it will be less dependant on a proper groundplane. (Note: this is a remark, not a request. )
