I use one of those for RC car bodies. It’s called a body reamer.

@@dadsrcworkbench1322 Great thanks for letting me know.

Yes, much more power efficient (and no screen helps too)

Thanks. Here the link where I bought the RAKWireless board (it is their official store) : store.rakwireless.com/products/wisblock-starter-kit?m=5&h=new-starter-kit&variant=41786684965062 I'm not sure if they have a US-based distributor but you could ask them

@@PoweredMeshtasticEurope Thanks!

I would like to paste links in the description but youtube forbids it under 1000 subscribers...

You will find them in the description of part 2

That's what I've also heard elsewhere but without any real life experience.

@@PoweredMeshtasticEurope my experience with them is in a solar weather station. I've had it for a few years and have seen temperatures as low as about -12c where it was still charging. So far there has been no appreciable loss in battery life. There is a period every winter where I don't have enough sun to charge the battery, and this year I had to charge it twice, which is the same number of times as the last few winters. I don't have any longer term data unfortunately, and I don't have any good way to measure capacity as it is integrated into the unit.

I got it from hobbyking years ago. It is a "turnigy" hand tool. Not sure it is still for sale but similar tools must certainly exist

@@PoweredMeshtasticEurope thank you!

I use one for RC bodies. In the rc world it’s called a body reamer.

Great feedback. What capacity battery do you have with this node ?

@@PoweredMeshtasticEurope 4x 18650 but these are used so ~10000mAh i used a parametric rugged case from printables as base and than added holes for the antenna, charging and a mount for solar panel. To access the USB-C Port you have to open the Case but the RAK can stay mounted. Sry, can't post a picture here. Also i used an additional tp4056 to charge the Battery from the Pannel as the RAK is known to be sensitive to overvoltage. The chip for charging in the RAK is also a TP40** and not a MPPT module. If you look at the schematics the 3.3V chip can only take 5.5V and this is the choking point (TP4056 could take more) I still want to test MPPT vs TP4056 to see the difference, but that will be for me heltec node where the 5W Panel is not enough.

@@JoergGebhard thanks for your experience. I will have to test the output voltage of the panel (should be 5V theoritically). If not, I'll use a TP4056 (have plenty laying around from a previous powerwall project) or a boost/buck converter.

That may work if there is enough sunshine. In what region and latitude do you achieve this? In Switzerland there are lengthy winter periods without almost any sunshine at all (depending on the location).

Austria, around Vienna, i planned measure currents from the panel and the Rak but this is an future project. location is Austria near Vienna ​@@frankfehlmann2083

It is the brand "Lemnoi" 6watts, on amazon.

@@PoweredMeshtasticEurope Thank you. 👍

To answer to this question I will simply put it to the test and see the results.
