what esphome presence detection sensor? - Lemmy.World
So I am looking to get precense detection in my living room. I think I want
mmwave as I do want to detect people that are sitting on the couch for example.
And I saw most don’t have a large distance and angle as my living room/kitchen
is 8m by 12m(in an L shape) so most with a 4-6m detection distance are not
enough. Also regarding the price I am looking at esphome with a hi-link sensor.
But I would like to get some recommendations if I should get a LD2420 or LD2410.
Some say the 2420 can’t detect a stationary target but the 2410 has less
range(6m vs 8m). So I thought place 2 LD2420’s for 120 degree 8m coverage in the
corner of the L with a esp8266. Would this work for stationary targets? (it
doesn’t have to be able to differentiate between the two just not be like a
infrared motion sensor). Also if you have done this and have found problems or
something to share please do so. Thanks for your sharing experience with one or
both of the sensors and your knowledge about this topic.
looking to solve some minor problems i have with my new honor magic 5 pro

looking to solve some minor problems i have with my new honor magic 5 pro - Lemmy.World
So i have since a few months a new phone the honor magic 5 pro and have some
things i am looking for and hope you guys might be able to help me solve the
problems i have i will list them from most likely you can solve them to least
likely. 1. i have loads of saved wifi passwords/names on my old huawei p20 pro
that i want to migrate to my new phone how do i do that (i currently don’t have
root on both phone’s but am willing to get it if it doesn’t void my warranty on
the new phone and doesn’t require me to do a new system install/wipe my phone
and doesn’t cost a crap ton of money (time is no issue)) 2. how do i optimize my
battery usage regarding refresh rate and resolution? put it on low or smart?
(both 60hz and low res is more than enough for me) also i have a app (track work
time) that checks my location often can i maybe limit its frequency in settings?
3. how do i teach the power management system to without me disabling it
(putting it off auto) in the settings not kill my mail apps and some other apps?
4. where is my wifi scanning frequency toggle in developers settings on my old
phone it only ran a wifi scan every 30 seconds or so but in dev settings there
was a disable rate limit switch. 5. do you know somewhere in the Netherlands
that has public wifi 7 so i can test if it works on my phone? 6. how do i map my
volume up and down buttons in the camera to something like manual focus or zoom?
7. in my camera app where is my megapixel setting or is there non and just high
res or normal? 8. can i in software (again i dont have root see question 1)
control my charging speed to limit it to something like 500ma instead of the max
a charger can supply? 9. is there a way to get an lower brightness than the
minimum on the slider? or will my display look just always display white at max
brightness(or what feels like it when its dark around me)? 10. is there a way to
get my 960fps 720p slowmo back from my 5 year old huawei p20 pro on my honor
magic 5 pro? Thanks for your help solving this issues for me or letting me know
if it can not be done.
Mining motherboard+ 10g network cards= cheap network switch?

Mining motherboard+ 10g network cards= cheap network switch? - Lemmy.world
So with Crypto mining being less profitable and miners selling their rigs for
cheap I thought how can I get my self a cheap managed network switch. I saw
mining motherboards with 12 PCIe 2.0 1x slots(4gbit bandwidth) and tought hey if
I plug in some cheap 10g 2port network adapters I can make my own network switch
with exactly the ports I need(SFP+ rj45). Put opensence on it and boom Managed
network switch with multigig(2gbit per port). Is there something I am missing or
have I found a way to get cheap multigig? Also can anyone who has a 10g only
network switch tell me what kind of power it is using per port so I can compare?
Thanks for debunking my idea and saving me a few bucks.
how to optimize battery life? - Lemmy.world
So I recently bought a new honor magic 5 pro. My last phone the Huawei p20 pro
was around 5 years old and started to show significantly less battery life. So I
want to use this phone again for 5 years. But now I wonder should I keep the
battery around 50% (65-35) and charge twice as often or should I 80-20 and
charge once every two days? Is there any science that proves one is better than
the other? Thank you for your information and sources.

looking for Hardboard decorating ideas - Lemmy.world
So i am building a 3d printer enclosure that is a 1.2m(4ft) square box. The
outside is made out of hardboard with 8 toggle latches to close/open 2 sides but
i don’t really like the brown look the hardboard has so i am looking to make it
nicer. So i would like some ideas to make it less brown and plain and more
modern/futuristic. All ideas are welcome image, drawing or just in text form i
need some inspiration. Thanks for all your ideas.
dust proof/waterproof switches vs not specified?

dust proof/waterproof switches vs not specified? - Lemmy.world
so i bought my first case+pcb+keycaps only needing some nice switches i have a
switch tester and decided i want to go with some nice red/linear switches. As i
am on a budget i am looking at some kailh and gateron and OUTEMU switches. I
noticed that kailh has box switches that they claim are dust proof/resistant and
OUTEMU has water/dustproof ip56 switches. I cant find gaterons dust/water
resistant switches. Now my question is: does this matter? like are normal
switches likely to fail due to dust and is going with water proof switches going
to mean i can spill my drinks on my keyboard? If not is there some gasket or so
that does make this last thing possible? Thanks for making this clear to me.
How does one come up with a name for a company?

How does one come up with a name for a company? - Lemmy.world
So i am in the middle of starting my own company in computer support(focusing on
teaching people how to use email, printer etc and solving problems that might be
standing in their way). But i need a name, website, Email and phone number. The
last one i have figured out as that is just a if it is kind of easy to remember
its okay. But figuring out an E-mail and website requires a name for the
company. I have heard some people that named company’s with their name in it and
regret it later. So how would one properly name a company? I am based in the EU
if it matters but i don’t think this is something that is different in different
cultures. Things i currently think about are (my name) tech service and (my
location(city)) tech service but i don’t know if that is a good idea and if i
might get regrets in the future(for example when expanding to more locations or
getting employees). Thanks for your vision on this.
what iso's are a must for ultimate ventoy disk(and what size is recomended)?

what iso's are a must for ultimate ventoy disk(and what size is recomended)? - Lemmy.world
hello guys i am wondering what are some must have iso’s for a ventoy drive? and
what size ventoy drive would you recomend (i am considering buying a 512gb, 1tb
or 2tb tranced 220s nvme) Back story: So i recently started my own “business” in
computer support and i need a drive to put ventoy on (its currently on a 32gb
micro sd card) so i can easily have memtest, ultimatebootcd and some linux
distro’s/windows install media and i am wondering if there would be any reason
not to go with the cheapest per gb drive(2tb) as i could then also use it for
some nice snappy file transfers. I am also looking to compile a list of iso’s to
put on it. As i mentioned before i already have a few things but you guys
probably have more suggestions for iso’s to put on a drive for
repair\troubleshooting. Thanks in advance for your advice on drive size and ISO
recommendations.
k80, 3060 or p40 for performance

k80, 3060 or p40 for performance - Lemmy.world
so i am looking to get me a gpu in my “beast”(a 24core 128gb tower with to much
pci-e) i thought i might buy a used 3090 but then it hit me most applications
can work with multiple gpu’s so i decided i was going to go with €600 to ebay
and using techpowerup [www.techpowerup.com/gpu-specs/] i figured out there
performance by looking at the memory bandwidth and fp32 performance. So this
brought me to the following cards for my own LLaMa, stable-difusion and Blender:
5 Tesla K80’s, 3 Tesla P40’s or 2 3060’s but i cant figure out what would be
better for performance and future proofing. the main difference i found is in
cuda version but i cant really figure out why that matters. the other thing i
found is that 5 k80’s are way more power intensive than 3 p40’s and that if
memory size is really important the p40’s are the way to go but then i couldn’t
figure out real performance numbers as i cant find benchmarks like this one for
blender [https://opendata.blender.org/benchmarks/query/?group_by=device_name].
