Plumeria Timelapse


#21

I didn’t go into the calculations, just have been constantly scaling up until it starts working :slight_smile:

The tomo didn’t arrive. I’ll get both the 2x and 4x version however in the meantime I’ve just received my new Xiaomi 20000mah Power Bank:

Took 7 hours to charge but now ready for some experiments. It also accepts pass-trough however when a power source is detected there is a little interruption which causes the Xiaomi camera to restart itself.

As for solar panel, yes they are probably also underscaled.

I have 2x 21W (anyway cannot connect both at the same time or do a serial mount, there is again probably an adapter or something which allows to connect 2 usb power source to have 1 output with more power but didn’t look at that yet).

This is what i’m using:

By themselves one of them is enough to power the Xiaomi cam (of course when they are on sun :))

But I have enough material to start playing a bit. I’m still waiting for my usb power multimeter:

To be able to monitor the “real” consumption and output at different stages.

YZX models are very good (but expensive) I have two models of USB meter much cheaper not as full featured but enought for my usage but I plan to buy a YZX

The Anker solar charger is nearly same as the one from Raven https://www.amazon.fr/dp/B01F71K574?ref_=ams_ad_dp_asin_2

But for the price you may want to go for this 42W model https://www.amazon.fr/dp/B01KVDOL7I?psc=1 that will ensure you to get better charging with bad weather condition

Yes but before going for a bigger version of the solar panel I first need to find the proper place for it :slight_smile:

It’s really not optimal right now since it’s never on full sun. It’s still charging but it’s why I really need a usb multimeter to be able to make some measures at this stage.

sure the panel’s location is definitly the wrong place :wink: but the bigger solar panel you’ll have to more “loss” you can afford not being full sun optimal exposure.
