Not in Berlin. I see them sometimes, but not often enough. I want one now ^^
Ok I figured out that I maybe can't charge NIMH batteries, but by connecting them to the 5V pin I can run the board off of them :) I'll try it and then report back!
Thank you very much
https://resource.heltec.cn/download/WiFi_Kit_32_V3/HTIT-WiFi%20kit32_V3(Rev1.1).pdf Lithium battery(≥250mA) min: 3.3 typical: 3.7 max: 4.2
So I guess I could try to run it on three AAA batteries. Worst thing to happen is I fry the board, which was only 10€. I'll wait for a reply here though
Edit: I meant AA batteries
Onboard SH1.25-2 battery interface, integrated lithium battery management system (charge and discharge management, overcharge protection, battery power detection, USB / battery power automatic switching).
Seems like this is only for lithium batteries. Maybe it can run off NIMH batteries but not charge them?
Which antennas do you have? How far does it reach?
Ok so I got myself a heltec v3 xD
If you want to use multiple internet connections and combine their speed, that's possible. Dunno how though and I guess to work best it would need a server somewhere else like a VPN to manage the packets coming from different ips
Because it's not useful. Two routers still share the same frequencies and thus can't send more data over the same air. A single router can already use multiple frequencies to increase throughput. You don't need two to do that. https://en.m.wikipedia.org/wiki/MIMO
Wow that's lucky
They are, refined fats and sugars are bad. Unrefined both are good.
Oh that's a good idea, I think supermarkets also collect batteries in general to recycle, maybe there I can find empty vapes.
