We’ve got them from Temu (or Shein) as my wife wants to grow mushrooms (the legal ones…) and chilis – I know from weed growing times (was never illegal in Austria, only flowering) the UV lamps use a LOT of power so we will see how LED holds up.

I found some time to adapt my old file upload script created on macOS 10.12 to work on more modern versions, in my case 10.15.

Install and use are very similar to the old version, encryption etc. of course stays as feature.

New GitHub as i lost the 2FA for my old one….

I had some time and went to Trsat (an upper area of Rijeka) to the church park to try out my setup – overall i am pretty happy what one can get between Temu, AliExpress and eBay. Total cost with the Powerbanks probably 250€. Not too heavy in backpack either.

For now i carry 2 20000Mah (..at 3.7V, at 5V 15k, 12V 6Ah – ca. 75Wh) Powerbanks which i use with 5V to 12V USB dongles (9V for the white lights) and 12V PD trigger modules. As backup i have a heavy 12V lead acid 9Ah, 6Ah usable – (60%~, also 75Wh) that i could carry also around (and a solar controller and a 40W panel, but that all needs a car then).

Below a video of a first trial.
