19:42 <DocScrutinizer05> Dyson vacuum, battery care instructions: "Do not store the device at <3°C after charging the battery. Do not charge the battery immediately after complete discharge, let the battery cool down first. The device normal operation and the charging process will shut down at temperatures <3°C, to protect motor(!?) and battery"

19:42 <DocScrutinizer05> LiIon battery

20:15 <atk> Dyson vacuums have batteries?

20:16 <atk> (handheld?)

20:16 <DocScrutinizer51> yes

20:16 <DocScrutinizer51> yes

20:16 <atk> Who knows

20:16 <DocScrutinizer51> hm?

20:16 <atk> 3°C is an odd temperature

20:17 <DocScrutinizer51> yes

20:17 <DocScrutinizer51> perticularly interesting is the rule to not charge and thrn store below 3C

20:20 <DocScrutinizer51> a recent article in c't mag claims there are 50 different LTE bands in use worldwide

20:21 <DocScrutinizer51> fifty

20:23 <DocScrutinizer51> in Germany the plan seems to be to keep GSM for telephony fallback and go for LTE for data and VoLTE calls

20:28 <atk> Why does everyone pick different bands?

21:05 <DocScrutinizer51> a very good questiom

21:07 <DocScrutinizer51> why did USA pick 850/1900 for GSM?

21:08 <DocScrutinizer51> iirc *allegedly* their military claimed demand for one of the internationally used 900/1800

21:09 <DocScrutinizer51> why has japan different FM broadcast than Eutope, Eastern Europe yet slightly different, and Japan totally different

21:10 <DocScrutinizer51> s€why has japan/why has USA/

21:11 <DocScrutinizer51> It prolly started with Marconi :)

21:14 <atk> It sounds like a total mess.

21:14 <atk> A total irreversible mess.

21:14 <atk> Although...

21:15 <DocScrutinizer51> well, yes, LTE seems more mess than even UMTS

22:15 <DocScrutinizer05> atk: https://www.dyson.com.au/vacuum-cleaners/handhelds/dc43h.aspx great appliance

22:36 <DocScrutinizer05> (battery <3°C) http://www.dyson.com.au/medialibrary/Files/Dyson/Support/downloads/ANZ/Floorcare/User guides/DC34_GENE_ANZ_220812.pdf p.8 >> CHARGING AND STORING THE DYSON APPLIANCE<<

22:43 <DocScrutinizer05> ((great appliance)) thanks to the 'pistol' trigger (instead a regular power switch) the usage pattern is more like for a drill or battery screwdriver, which is *very* convenient since you can stop vacuum instantly when you suck a paper or whatever

23:44 <ShadowJK> As someone who recently welcomed a puppy into the house, I find myself disappointed in vaccuum cleaner performance

23:48 <arossdotme> :)

23:48 <arossdotme> i know what you mean
