Re: loboris MicroPython_ESP32_psRAM_LoBo fork

None of that has ever been challenged in court and I don't really care how many opinions about it have been posted online. Code that had appeared in a repository at some point doesn't poison all the rest of the code there forever. If that were the case no commercial product that was successfully scr...

Re: loboris MicroPython_ESP32_psRAM_LoBo fork

If you've followed discussions in the industry on the GPL, the received wisdom is that even if a developer has seen GPL code before writing his own version, his solution (and hence the entire codebase) could be challenged. Strict "clean room" conditions are required when re-implementing GPL code. T...

Re: loboris MicroPython_ESP32_psRAM_LoBo fork

Loboris apparently went through his code and cleaned out what little GPL there was back in 2018. But the remark by dpgeorge about it was made on Jul 25, 2019 so it looks like he still considers the repository tainted. Seems unjustified to me.

Re: loboris MicroPython_ESP32_psRAM_LoBo fork

"hard to know if such code was/wasn't influenced by GPL code", that's silly. You could say that about any code anywhere. I think it's just a weak excuse for NIH.

Re: powering ESP32 with a battery

It sounds like most LiMnO2 aren't suitable for outdoor use? Also the ones I am seeing have a very low discharge current rating. Where are you getting LiSOCl2 batteries with a good current output? Here's one that is under 200mA, may not work for ESP32. https://www.amazon.com/dp/B07K8G2QBM/ref=sspa_dk...

Re: powering ESP32 with a battery

Ah, got it. Not rechargeable but not really necessary to recharge them for quite some time for many IoT applications. And inexpensive enough to just replace eventually.

Re: powering ESP32 with a battery

Interesting! LiSOCl2 batteries I am seeing deliver 3.6V, which is the very top of the ESP32 range but should work. LiMNO2 batteries make 3V. Long shelf life is great.

How much do they cost? I am seeing these batteries online but no prices. Do they require special chargers?

Re: powering ESP32 with a battery

Thanks for sharing that info. Expensive battery! I am looking at some other alternatives like this; https://www.batteryspace.com/lifepo4-18650-rechargeable-cell-3-2v-1500-mah-4-5a-rate-4-8wh-with-iec-62133---un38-3-passed.aspx with similar capacity and a lot cheaper. Very possible that the charger I...

Re: powering ESP32 with a battery

Nice project!

I see that you are using a 18650 battery. What brand is the battery and where do you get them? Also curious to know how you are charging them. It's possible that the charger I am using damages the batteries.
