content: Dave said in his podcast that there is no plant to work on / finish the uSupply.It's sad.To solve this problem, i took one of this cheap Power supply modules which are available at E-Bay, Amazon, Aliexpress,... put them in a box and connect it to my model plane 24V battery.There are USB-C modules available which are handling the USB communication to get full voltage output from USB-C power banks / charging adapter.Perhaps this would be an solution for you?But be carefull.There are multiple USB-C power standards.Not every charger / power bank understands every standard and refuses to deliver full voltage.

content: # Skip to 5 mins if coins ain’t your thing.# Dave, what’s going on with your audio quality recently? It sounds SO low quality, compressed and has that ghastly audio “shimmer” effect; is it YouTube compressing it? I’m no audio snob, but this sounds almost as if you’re lispiing!# Re the “Marauder” torch (what a silly name, replete with all the hard edged “macho” styling) - I don’t quite think a professional search and rescue team would be buying cheap Chinese consumer grade tat like that!

content: The Hoymiles HM-xxxx series uses a proprietary 2.4RF protocol based on the Nordic NRF24L01+ chip.Some hackers on the German microcontoller.net forum have reverse engineered the 2.4GHz protocol and there are two open source projects for the ESP8266/ESP32 that can read the HM-xxx's datahttps://github.com/tbnobody/OpenDTUhttps://github.com/lumapu/ahoyI tried to post this information three times in the video comments. But youtube always deleted it.regards,Chris

content: Actually the Blueair does produce ozone, how could it not, it has ionizers on the side/bottom air intakes.https://smartairfilters.com/en/blog/how-blueair-purifiers-create-dangerous-ozone/Quote(I don't know how reliable those measurements are)But anyway, I have a Blueair 500 also, and I'm satisfied with it too.
