02:14:35 <Kuschelpony> goodevening
02:22:51 <arch> hi
02:24:04 <Kuschelpony> hello arch
02:28:34 <MrMobodies> I have a question,
02:29:02 <MrMobodies> with NVME ssd's where labels are placed ontop
02:29:13 <MrMobodies> in the enclosures with the thermal tape
02:29:41 <MrMobodies> if I remove the sticker, can that help improve heat transfer to the thermal tape onto the metal casing?
02:31:20 <Kuschelpony> most likely yes...
02:31:48 <MrMobodies> https://i.imgur.com/eJ5NPRu.png
02:32:34 <MrMobodies> I see, so if they were to put them on the back and some laptop motherboards designs dissipate heat on the back
02:33:00 <MrMobodies> I suppose I could just peel the label off and put it on the back or wherever
02:34:47 <MrMobodies> what I could also do in time if they wear out
02:34:54 <MrMobodies> is try the copper shims
02:35:10 <MrMobodies> but it seems to manage well
02:37:48 <MrMobodies> Was very upset yesterday to find this return after 6 months
02:37:49 <MrMobodies> https://i.imgur.com/LDkNHRh.png
02:39:06 <MrMobodies> my mum ran out of the usual stuff, Sainsbury's didn't have any so she settled with ths
02:39:14 <MrMobodies> https://i.imgur.com/Wo4XQHa.png
02:40:02 <MrMobodies> blob:https://imgur.com/a9052526-60c5-4c88-a56a-e898194adeed
02:40:08 <MrMobodies> oops, https://i.imgur.com/B8p9av0.png
02:40:13 <MrMobodies> it has perfume in it
02:40:38 <MrMobodies> fortunately I have a half a box left she got me
02:41:25 <MrMobodies> https://i.imgur.com/z2yWxAc.png
02:41:27 <MrMobodies> No itching
02:41:47 <MrMobodies> no powder remains, no bubbles after washing to that extent
02:42:49 <MrMobodies> When I read this bit:
02:43:06 <MrMobodies> on that thing she got: https://i.imgur.com/UQNuioC.png
02:43:36 <MrMobodies> I then realize the people making this stuff has no intentions of cleaning my clothes properly
02:44:58 <MrMobodies> "To respect the environment use... the lowest recommended temperatures 30c AND DO FULL LOADS in order to minimize energy and water consumption..."
02:45:29 <MrMobodies> This is where my clothes don't get clean... they have no respect for the job at hand. Form over function.
02:45:37 <MrMobodies> What do you think of that?
02:46:27 <MrMobodies> Oh to kill the germs I read the NHS suggests at least 60c... maybe they add the perfume to hide the smell that would otherwise be there at such a low temperature wash.
02:48:17 <Kuschelpony> i absolutely suggest to use occassionally 60°C espically for underwear, that actually helps for a longer life of the washing machine as it kills the germs that might also degrade the rubber parts
02:49:32 <MrMobodies> that's a point, maybe that's why ours lasted over 6 years.
02:49:51 <MrMobodies> because I had been filling it up manually with hot water from the tap through jugs
02:50:54 <MrMobodies> when I discovered in 2020 one night why my clothes wern't being cleaned properly where I sat there and observed it for 3 hours.
02:51:32 <MrMobodies> 10 years of this problem which first started out in 2011
02:51:49 <MrMobodies> I didn't know the new washing machine then didn't come with a hot water inlet at the time.
02:52:40 <MrMobodies> I kept on washing again and again from 2011 and then my dad told me years later that this one didn't come with a hot water inlet
02:52:52 <MrMobodies> and that it is costing him a lot everytime I use it
02:53:12 <MrMobodies> solution: fill it up with hot water so it doesn't have to heat the water up all the time.
02:53:24 <Kuschelpony> yep!
03:11:48 <arch> Kuschelpony, i bought a cheap china amplifier. supposedly "200W". obviously i know that is a load of baloney. it's 100% using a chipamp that can maybe do 20W. anyway, it has a bit of hiss. any tips on quick fixes? maybe a R+C filter across output?
03:12:26 <arch> the hiss is not noticeable when i have music playing
03:12:35 <Kuschelpony> oh, modern Class-D chipamps can do 30 to 50W without heatsink and 200W with heatsink totally well
03:13:02 <arch> this is the model i bought: https://www.amazon.com/dp/B0B9R3N9L2
03:13:02 <EEVBot> [url] Amazon.com: Daakro AK35 200W Dual Channel Bluetooth 5.0 Stereo Audio Amplifier Receiver, with USB, SD Card Input, Bass & Treble Control, Wide Compatibility : Electronics | www.amazon.com
03:13:21 <Kuschelpony> the hiss is likely a mix of too high gain (most builders do this from a fear that people would complain about "not loud enough" from sources with too low voltage)
03:13:24 <arch> it's actually a good deal for the price. has bluetooth and aux, can run from either mains or 12v power adapter
03:13:45 <Kuschelpony> and crap input capacitors, microphonic ceramics, also often missing and RF ingress filtering
03:14:16 <Kuschelpony> i do have a couple of TPA3116 amplifiers that run absolutely fine after a number of modifications
03:14:43 <Kuschelpony> your module looks like it needs a lot more reverse engineering, that i cant do just from photos
03:15:12 <Kuschelpony> but perhaps it would just need a few different resistors and probably somecapacitor change to run a lot better
03:16:04 <coppice> There used to be lots of cheap simple TPA3116 amps from Chinese companies like SMSL, but the makers seem to have gone up market and abandoned that space
03:17:21 <arch> i am going to open it up in a few
03:18:08 <coppice> Its really unusual to see something like that with the PSU built in these days
03:18:28 <arch> it's probably using some nonsense SMPS without any filtering
03:18:33 <arch> i dont use the mains. i use adapter
03:19:29 <arch> my mom's rv has a cheapass chinese tv without adequate emi filtering. any time the tv is on, the radio gets a crapton of static
03:20:06 <arch> same for some of the LED lights i bought for the rv; any time i turn on a particular LED light, the radio craps out
03:20:24 <coppice> You don't need to look to China for poorly filtered products. They are a global phenomenon
03:20:42 <arch> i can only imagine the headaches ham radio operators have to deal with on a daily basis, dealing with cheap chinese junk
03:21:17 <arch> we need T3sl4 to be head of EMI department. maybe i'll ask Trump to put him in charge
03:21:19 <coppice> globally there are plenty of expensive products causing just as much trouble
03:22:00 <T3sl4> my reign will be more terrible than that reeses coffee mug fuck
03:23:06 <arch> T3sl4 be like: "you fail EMI test? believe it or not, jail. you over cook capacitor? you right to jail. we have the best EMI compliant electronics in the world...because of jail"
03:23:34 <T3sl4> corporation? jail
03:23:43 <T3sl4> (or kickbacks, because trump would have it no other way)
03:27:30 <arch> (in case anyone didn't get my jail reference above: https://www.youtube.com/watch?v=eiyfwZVAzGw

05:02:18 <Kuschelpony> i asked Stablehorde how to wire a schuko plug to VDE standards, but i still dont understand this https://cdn.masto.host/sigmoidsocial/media_attachments/files/113/476/924/959/666/631/original/dacf7486774cbf5b.jpg
05:07:51 <coppice> Is this some kind of power socket with an aerial socket in the middle?
05:09:21 <Kuschelpony> whatever happens in the digital brain-emulator
05:11:11 <coppice> Interesting how it find a crumbling border to be a key feature
05:12:53 <arch> so i did open up that amplifier Kuschelpony. its got no input filtering on the mains. it's using a "topswitch" or similar chip for a flyback topology power supply. here's a picture: https://i.imgur.com/VC7E1sw.jpeg
05:13:29 <Kuschelpony> i dont even try imgur anymore... but i do know enough of such stuff
05:13:46 <Kuschelpony> that said, its likely an interesting reverse engineering project :)
05:13:53 <arch> what's wrong with imgur
05:14:08 <Kuschelpony> flyback witcher ans no input filtering is asure way to noise problems btw
05:14:24 <Kuschelpony> arch, it does not work for me anymore, even with javascript enabled
05:15:00 <Kuschelpony> never gives me a link to the actual image, only redirects to a page rendered blank
05:15:25 <arch> they must have enabled hotlinking prevention
05:18:45 <coppice> flyback switchers ARE noise sources. Generating stable DC is just a byproduct of that.
05:29:18 * flyback bites arch Kuschelpony and coppice
05:59:04 * electrohead inserts fire
