I have no way to test my RAK fiberglass antenna, I don’t have equipment but have not found it to be much different to a small sma type antenna when out trying TTN Mapper. Not willing to point the finger however as I really have no way to know which is “betterer” or which is “worser” than the other!!!
Does anybody know where can I find this antenna connector footprint (SMA and U.FL) for Eagle (or any other library)?
_thinking ’ if I use an 8x8 led matrix I can easily visualize a gateways activity on all channels receiving TTN’s meta data on a RPI zero – LoRaVU™
So 8 ‘lightbeams’ , reflecting the channels and the signal strength. ( a color led matrix could show green led’s for TTN traffic and red for KPN’s 
)
Portable (wifi) and small and maybe useless So worth building.

The single mini blue led matrix I had in stock is not very interesting to watch, So I ordered a bigger 8x8 Bicolor LED matrix (red / green / yellow)
* think I made a stupid mistake - you can’t subscribe to everything that a GW under my control received, So I can’t filter hence not control the matrix leds 
sure it works for an specific application or a specific sensor but that’s not what I wanted in the first place
difficult to capture

Some tiles due here any day now for an other Micropython project but decent size and one pin/wire and all colours has to be a win!

Do you have problems with BME280 sensors in outdoor use? I have one and it stuck on 52% of humidity. Also have some problems before with BME280.
Do you have advice for positioning, enclosure and things like that? Thanks!
hardware stored for a rainy day 
did you try a hairdryer… maybe there is moisture inside

powerunit (16000 mA / 2x 7565121 lipo) for the 'senior citizen assistant.
I always ‘pack’ lipo’s in handheld and outdoor projects, in extra Kapton tape.
They can handle high temps and give some extra protection
some extra shielding for possible body interference from the hands
going to mount this BIG round diffused dual color LED as feedback indicator.
did google understand your question ? is the device on ? need the battery charged ? do we have internetconnection ?
test while waiting for 'soft on/off parts
Finished hardware build for the RAK5205 Tracker with Qi Wireless Charging, had to expand case slightly as charge coil/circuit bigger than planned! The USB charged version is some 0.5cm smaller. Shown here next to RAK tracker housings for comparison
In use on charging pad here (when charging the translucent plastic allows the internal red charging led to shine though 
)
Have also received (yesterday) the new Onethinx module/Kit
Only problem now is do I finish the Tracker PoC work and s/w dev, finish the RAK DIY/Enterprise GW Build/test deployment/review write up or look at the new toy from Onethinx 
… or get on with rest of the day job!?

nice… wireless charging !
Using a 3.7v 1200mAh LiPo with 20 min GPS updates and 10-12 min mems updates (T/H/Pressure/x-y-z acel) + battery status I get just under ~2 full days operation with charging from flat to ~80% capacity taking 2-3 hrs and 100% 4-5Hrs. Fits nicely with the clients planned 1-2 working day use with end of shift charging potential (end of day/overnight)…if forgotten/missed one day enough capacity for 2nd day before charging. Need to spend time improving lower power modes and optimising update rates based on client feedback from use over next month or 2…

I might have to invest in something like this for Qi charging in the field! (8000mAh - not 50000mAh - a bit optimistic me thinks!
BoRROz:did you try a hairdryer… maybe there is moisture inside
I tried, but when I take it out, same happens.
stuck on exactly 52% ?
Few percentage difference, but stuck again… Temperature and pressure are measured ok. I had before one BME280 sensor which was stuck od 100% when outside even when was hot and dry air. I use it inside now and works great. Probably it is problem with water inside.

Yes I need something like that, but I want it to switch on/off the Pi + AMP with 3.7v.
Then feed it into the DC-DC to get 5v, So a soft switch for a battery operated Pi.
