those steps might be only thing saving you...

2019-06-22 09:15:41 UTC  

but if you really have 24 cans just get one of mini compressor camping fridges/coolers/freezers

2019-06-22 09:16:50 UTC  

this type is still inefficient? if I ran tubes from it to the cans, liquid inside tubes, wouldn't cool can down 40F or whatever in minutes?

just fucking no

2019-06-22 09:17:36 UTC  

also that block for sure as heck aint foodsafe

2019-06-22 09:17:56 UTC  

``` Peltiers only have 10-15% Carnot efficiency, using 50 watts you can move a net ~3 watts of heat, less your design inefficiencies.```

to quote my notepad

2019-06-22 09:18:19 UTC  

oh, god, they're that bad?

2019-06-22 09:18:28 UTC  

YES THEY ARE FUCKING BAD

2019-06-22 09:20:47 UTC  

i dont mean to sound mean or agressive over this but "usable peltier usecases" as book is shorter than french war victories

2019-06-22 09:21:29 UTC  

and shitty compressor coolers/fridges cost 100~ish dollars these days

2019-06-22 09:21:40 UTC  

and can provide tons of more value

2019-06-22 09:22:50 UTC  

and if you look at the bottom of the can the peltiers main cooling wont even reach anything else but the really really small surface area there

2019-06-22 09:23:18 UTC  

thus the holder is needed part for it.. and even then it kills the efficiency to sub 1 watt most likely what eventualy reaches the can

2019-06-22 09:26:15 UTC  

even getting party cooler and dry-ice for the cans is more valid option

2019-06-22 09:26:20 UTC  

than those

2019-06-22 09:26:22 UTC  

:D

2019-06-22 09:28:16 UTC  

my second pair of VE monks are failing. I like their sound better than other brands, so I'm buying the cheapest braided cable earphones on aliexpress to replace the wires

2019-06-22 09:29:08 UTC  

@uuuu <#365921969004216320> might have proper cables only option for you too (dunno how much more expensive its compared to cheapest earphones)

2019-06-22 09:30:47 UTC  

@ikillu Peltier cooler is one of those things what is every studying engineers "magic bullet to everything" until they got more and more education they learn how shitty they are.... and some dont believe it or smell money on it still and try to launch shitty products just to cash people

2019-06-22 09:31:21 UTC  

yea, there was a kickstarter project, guy backs it gets product, uses it, and it just dropped temp of can not even 20F lol

2019-06-22 09:31:32 UTC  

just read that now, thanks for opening my eyes

2019-06-22 09:33:28 UTC  

it'll probably sit on there 24hrs, 50w lol to make it cool, not even cold

2019-06-22 09:33:45 UTC  

50*24 W

2019-06-22 09:33:51 UTC  

to not properly cool a can

2019-06-22 09:34:01 UTC  

yep sounds about right

2019-06-22 09:34:03 UTC  

yea, .20 or so in electricity LOL

2019-06-22 09:34:08 UTC  

cents

2019-06-22 09:35:02 UTC  

peltiers need darn good cooling on themselves and they need giant walls of insulation and door what is well insulated to keep things cool

2019-06-22 09:35:55 UTC  

yea, if you fit the can in an enclosed area, maybe then, and insulated it too

2019-06-22 09:36:00 UTC  

and at that point its not marketable anymore and you are speaking large enough thing that small compressor engine is way better option

2019-06-22 09:37:16 UTC  

unless you have specialy designed peltier coolers what have piping laid into the ceramic what can cool anything that moves tru those pipes

2019-06-22 09:38:02 UTC  

then waterspray-loop for cooling cans but even then its just cheaper to pay that 100 for proper fridge

2019-06-22 09:38:32 UTC  

(and nobody does those custom peltiers for price what would be profitable nor sane just cause they are not worth it)

2019-06-22 09:54:11 UTC  

a small mini fridge that can do a 2l bottle or a few cans would be cool

2019-06-22 10:26:55 UTC  

just make sure its compressor one :P

2019-06-22 10:35:57 UTC  

@ikillu what if I'm gaming for 36hrs and have like 24 cans of coke on standby for my vidya marathon, I don't want to leave my bedroom to head to the kitchen, that's what I need this for badly

2019-06-22 10:36:08 UTC  

I hope every word in this run on sentence is a lie

2019-06-22 11:38:52 UTC  

i mean such lan-gaming events are not unheard off nor that uncommon among streamers who do it for sake of charity etc

2019-06-22 11:39:15 UTC  

but i do agree that taking that much toll to ones health is ridiculous

2019-06-22 11:39:41 UTC  

where as the walking is probly the livesaving part
