24:59 <arch> yesterday i learned something new while flashing my DIY controleo2 reflow oven with updated defines. when i changed up the relay mapping and reran the setup, the LCD screen would bug out and display gibberish and freeze the system. so to fix it, i had to first zero out the eeprom and reupload the firmware
25:53 <T3sl4> pins stored in eeprom wtf
28:01 <K> looks like someone changed config layout in eeprom and did not bother to check backwards compatibility

30:57 <Ampera> Ysjoelfriend!
31:00 <Ysjoelfir> my cheek pain is very much gone, almost
31:02 <Ampera> did you end up getting to the music?
31:05 <Ampera> this is good
31:17 <Ysjoelfir> not yet sadly. but I will within this week
31:41 <Ampera> I flash modded my 3rd gen iPod. Went from 10GB to 128GB
31:43 <Ampera> now listening to music on it
31:49 <arch> to clarify: the program has defines in a header file which is used to get or set reflow/presoak/soak/whatever settings: https://github.com/engineertype/ControLeo2/blob/master/ControLeo2/examples/ReflowWizard/ReflowWizard.h#L53

32:04 <Ysjoelfir> right now my ADHD kicks in and makes me listen to Hindarfjäll - Laerads Limum in an endless loop.
32:41 <Ysjoelfir> oh, arch is building a reflow oven?
32:43 <arch> and because i remapped some of the pins, while NOT clearing the eeprom, it loaded the old eeprom settings, which i am guessing pulled down/up some LCD pin, causing it to bug out
32:50 <arch> Ysjoelfir, i already have TWO :D
32:57 <arch> a cuuuutey Dash Oven
33:07 <arch> and a Black and Decker 1200W one

33:29 <arch> and both use Controleo2 (DIY copperclads)
33:35 * T3sl4 pinches arch's scrumptious cheeks
34:19 <arch> kyaa, ecchi! *me squeals in an annoying anime girl voice and slaps T3sl4, leaving a hand print on his face*
35:29 <Ysjoelfir> damn arch, that thing is absolutely cute :O now I want one. but we have one of these LPKF thingies at work, so I don't really need one
36:22 <arch> it is cute...also was pretty challenging to stuff so much stuff in there. namely the PSU board, that thing was just ~2mm away from the hot wall, which is why i used reflective tape underneath
36:58 <coppice> Ysjoelfir: if you have an LPKF surely you need something?
37:00 <Ysjoelfir> I assumed it might be a tad tight in there. but it looks very nicely made
37:13 <Ysjoelfir> coppice - yes, money.
37:54 <coppice> How do you describe an LPKF machine without a thick layer of dust on it?
37:56 <coppice> New
39:42 <Ysjoelfir> This one has had like... 2 meters of dust on it before I took it out of storage
40:01 <Ysjoelfir> and I actually wonder if I should convert that to a controleo thing, as the firmware on it is shitty as fuck
41:25 <arch> go for it. if you need the files, i can provide them
46:39 <arch> oh man, i really need to add a manual fan controller for this firewall. it's fucking loud
46:54 <arch> whiney ass fan. that's the problem with small firewalls
47:27 <arch> tempted to just dremel out the case and strap on a 3 pound aluminium heatsink and remove the fan\
48:42 <Ysjoelfir> I don't think I have the time for the conversion though.... and regarding noisy fans: Soon we will swap out 3 switches in house here to put mikrotik ones in place. 48 ports PoE on one. I am not thrilled to have that in the office right across the floor.

39:45 <okhsunrog> can I ask a question about designing a dc-dc boost converter here?
39:57 <Kuschelpony> yes
40:04 <Kuschelpony> maybe we even have answeers#
40:10 <Kuschelpony> maybe we even have answers
40:22 <Ampera> some of us just have farts and bad smells
40:44 <Ampera> like arch
41:21 <okhsunrog> so I want to make a syncronous converter, input voltage is 12v to 28v, output is 30v to 42v. max 5 amps. I can't find a correct way to calculate how large my input capacitor should be
41:38 <okhsunrog> i bought a hybrid polymer for 1400 uF
42:08 <okhsunrog> is that okay or too much?
43:20 <arch> okhsunrog, the capacitance depends on things like how much your ripple will be. sounds like you are making a synch boost conv
43:21 <coppice> What frequency is it running at? What impulse response do you need? What is the impulse response of the upstream power supply?
43:27 <arch> boost converters have continuous ripple current
43:41 <okhsunrog> 75 khz is the freq
44:07 <arch> are you living in the 90s? there's modern day synch boost controllers that do a few hundred khz...
44:08 <okhsunrog> @arch yeah, sync boost conv
44:17 <arch> you;re going to need an extremely beefy inductor at 75khz
44:35 <okhsunrog> yeah, already made a beefy one haha
44:44 <arch> ah ok, so this is for learning, not production?
44:57 <okhsunrog> just my esp32 can't do high freq pwm with good accuracy
46:07 <okhsunrog> i'm designing a charger for my electric skateboard. the dc-dc take 28v 5a from my pd3.1 power supply and uses cc/cv algo to charge the battery
46:24 <arch> i dont have a clue how to make a microcontroller behave as a pwm controller, but this is the website you can use to calculate things like ripple and inductance: http://schmidt-walter-schaltnetzteile.de/smps_e/aww_smps_e.html
46:25 <EEVBot> [url] Boost Converter | schmidt-walter-schaltnetzteile.de
46:49 <okhsunrog> thanks for the link
47:02 <arch> i would not trust using an esp32 for doing something critical like charging a lipo battery
47:11 <arch> you're playing with fire (literally)
47:25 <okhsunrog> I'm going to draw about 5a from my type c charger and I don't want it to turn off because of current limit
47:41 <okhsunrog> why? esp32-c3 + freertos
48:03 <okhsunrog> is it dangerous? I'm going to monitor current + voltage + temp
48:36 <okhsunrog> I have a good BMS, nothing dangerous could happen
49:44 <okhsunrog> also my battery is 42v 15 a/h. 5 amps of charging current is nothing for the battery
50:18 <okhsunrog> and the power supply that feeds dc-dc converter just can't provide more than 28v 5a
50:49 <okhsunrog> what's the worst thing that can happen?

52:29 <arch> looks like 7A ripple current on input, you can use 4 aluminium polymer caps (each should handle 2A min)
53:53 <okhsunrog> https://ibb.co/y6qdWCr
53:53 <EEVBot> [url] PXL-20230222-195217089 hosted at ImgBB — ImgBB | ibb.co
53:56 <arch> don't need crazy high capacitance on boost reg input. you're not doing something like off-line converter where you need to have hold-up times for brownouts
54:42 <arch> that's a lot of jizz. damn man. that inductor did not deserve that
55:03 <okhsunrog> I just don't want the current ripple to mess with usb type c charger. it's a pd3.1 140w charger from baseus
55:41 <arch> how will it mess with the usb c charger? it should have short circuit and overload protection unless you got the lowest priced crap off alibaba or aliexpress
56:07 <arch> anyway i will be back later in like 1 hour
56:09 <okhsunrog> i mead I don't want to overload the charger
56:13 <okhsunrog> okk
56:15 <okhsunrog> thanks
57:44 <arch> in order not to overload the charger, you need to limit the power drawn. you need soft start as well as current limiting on the low side as well as high side
58:09 <arch> i feel like you're gonna have a tough time going this route. modern day synch boost controllers do all this for you
58:17 <arch> and much safely
58:36 <arch> psa as posted by T3sl4. you should read it: https://imgur.com/a/M1S0DbI
58:36 <EEVBot> [url] PSA for EEs and Students - Meme on Imgur | imgur.com
03:01 <okhsunrog> I know, I have one INA237 at the input and one INA237 at the output, I'm going to limit the input current in my algorithm
04:13 <okhsunrog> I know about the soft start too
05:26 <irc> haha arch I did not know that chip
07:42 <okhsunrog> arch, about that like you gave me... yeah, I know what my inductor current ripple is going to be, I already calculated that. what about the input current ripple? how to calculate the input capacitor. i guess I went the wrong way and chose too beefy capacitor + pre-charge circuit for it to prevent sparks haha
07:48 <okhsunrog> *link
07:51 <okhsunrog> not like
10:07 <okhsunrog> that's what I bought https://product.tdk.com/en/search/capacitor/aluminum-electrolytic/hybrid-polymer/info?part_no=B40600A7148M011
10:14 <okhsunrog> now I regret it

14:09 Quit: Kuschelpony ([email protected]) Connection closed
15:54 <okhsunrog> so my inductor ripple current is about 0.6a
17:16 <okhsunrog> i need my input ripple to be about 0.1a of better. what capacitor do I need?
29:30 <arch> why are you making your input ripple so low?
29:38 <arch> there is no reason for it
30:20 <arch> your output ripple will be large because it being a boost converter. when the boost converter mosfet snaps off, you will get a pulse of current thru the synch mosfet
31:21 <arch> likewise your peak current will be large in a boost converter. 21A from that calculation: https://i.imgur.com/gi1igGC.png
39:09 <arch> input current ripple, to respond to your previous question, is dependent on the inductor. higher inductance = less input cap ripple. but the higher the inductance, the worse the losses due to winding resistance, and worse transient load characteristics. as to how to calculate input capacitance, you need to decide on a tolerable input ripple voltage (say 2% of the V_in_max, so 0.56V). and then you can do: C=I*(dt/dV) --> C=(21A)*(9.6us/0.56V) -->
39:09 <arch> C=360uF
39:53 <arch> someone lmk if i got that wrong
41:25 <okhsunrog> it's for 16 uH on your picture
41:26 <arch> sorry, it wouldn't be the peak current. that's a mistake. you want to use the inductor ripple current as your "I" and D-off time as the dt
41:35 <okhsunrog> my inductor is 220 uH
42:55 <arch> iirc, such low ripple fractions will cause problems in the control loop
44:34 <okhsunrog> what problem with control loop? I just measure the current and voltage 200 times per second and increase/decrease the pwm duty cycle based on that. I don't need a really fast control loop
44:47 <okhsunrog> it's a battery, not a cpu
48:39 <arch> yea, let's wait for T3sl4 to drop by. he probably has something more knowledgeable to say
49:03 <okhsunrog> okay
49:30 <okhsunrog> any advice for a good irc client for linux?
50:03 <arch> hexchat, irssi (cli), pidgin
50:23 <okhsunrog> do you use archlinux?
51:16 <arch> nah, that's just a remnant of when i used to
51:29 <arch> tahts when i registered the nick lol
51:38 <okhsunrog> lol
51:44 <okhsunrog> what distro now?
51:48 <arch> fedora
52:03 <okhsunrog> cool. I used to use it
52:07 <okhsunrog> now I use archlinux
53:36 <okhsunrog> oh damn. so 100 uF is fine for me
53:40 <okhsunrog> what a relief
55:19 <okhsunrog> another question. I also have a few buck converters in my circuit. like for 5v, 3.3v, not powerful, less than 0.5a of output. can I use one input capacitor for all of them?
55:38 <okhsunrog> i don't see any reasons to put a few parallel ones

05:19 <arch> that's right, just 1 is fine for those. use a small ceramic for those
05:52 <arch> 4.7uF, 10uF, more than enough, since you already have bulk decoupling nearby
08:05 <okhsunrog> okay, hybrid polymer electrolytic for 120 uF (I already have this one, is it okay for that purpose? https://product.tdk.com/en/search/capacitor/aluminum-electrolytic/smd_capacitor/info?part_no=B40940A8127M000). and a few ceramic for 4.7 uF

18:11 <MrMobodies> I just discovered that the adaptor does not fit the Xbox controller
18:25 <MrMobodies> same round shape but different fitting insde

21:06 <MrMobodies> first no game
21:12 <MrMobodies> second wrong controller

23:15 <MrMobodies> no wonder why it was in filthy condition with the rubbery bits were very sticky
23:33 <MrMobodies> I cleaned it all up with some alcohol
24:03 <MrMobodies> I thought these things came with two controllers
24:48 <MrMobodies> but I find it strange how that ended up in it's original box with a controller for a really old model
25:03 <MrMobodies> that don't fit
33:14 <arch> do you have a scope? you can always measure the ripple waveform
33:53 <MrMobodies> no I don't have a scope
34:05 <MrMobodies> the adaptor is on it's way

47:24 <rust6> well, you just have to put it back in the box. Maybe ask if he has a controller that fits, because the one you got is wrong.

35:28 <MrMobodies> Hello
35:40 * Ampera flings chunks of duck at electrohead 
35:47 <Ampera> I dismantled a duck.
35:57 <electrohead> <3
36:01 <Ampera> took all the bones out, cut it into cubes, it will be curry tomorrow
36:04 <electrohead> duck is amazing, when cooked correctly
36:28 <Ampera> In the past I've smoked it whole. I think that's the greatest mistake.
36:37 <MrMobodies> did you buy the duck dead?
36:45 <MrMobodies> or did you kill it fresh?
36:54 <Ampera> I need to try it in the future, but breaking it down and deboning most of it feels like it might end up with a better result
37:05 <Ampera> (you know, if you aren't making curry)
37:14 <Ampera> MrMobodies, I bought it frozen and hard as a rock from Aldi
37:21 <MrMobodies> smoked duck, reminds me of the spring rolls I once had very noice with hoisin sauce
37:35 <MrMobodies> Aldi. I didn't know they operated oversees
37:44 <Ampera> they operate in most of the civilized world
37:57 <MrMobodies> I think they are building one in Eastree, just under a mile down the road from me.
37:58 <Ampera> Of course, originally a german store
38:13 <MrMobodies> I like ther chocolate filled donates

41:31 <Ampera> MrMobodies: exactly 2.7VAC +/- .0005 @ 27.3khz
41:49 <Ampera> for all currents and resistances
42:19 <Ampera> a tan wave, with spikes going to +/- infinity
44:43 <MrMobodies> so if I produce that back through the probles
44:53 <MrMobodies> I could reprogram his brain

15:47 <arch> i flashed my old Black & Decker reflow oven as well with the new changes (i removed the artificial duty cycle limitations on the top and boost elements. doesn't make sense.
17:10 <arch> maybe i should sell a few of these Dash reflow ovens
17:19 <arch> market's not here tho
17:23 <arch> !shrug
17:23 <EEVBot> ¯\_(ツ)_/¯
19:56 <arch> i stuck my finger thru the thermostat hole during the reflow process to see if the pcb would get hot or not, and it did not get noticeable warm inside the control chamber
20:23 <T3sl4> giggity
20:24 <arch> so no worries on the longevity even with the tight fit. should be fine so long as you don't do back to back reflows

56:01 <T3sl4> hey orange chicken
05:21 <K> hello third socks
09:26 <Halcyon> T3sl4, did you watch that video by Brian Lagerstrom as well?
09:39 <T3sl4> lol, i did
09:49 <Halcyon> I definitely want to try it this weekend
09:53 <Halcyon> It looks fucking amazing
10:10 <Halcyon> I love his crissss chicken
10:25 <T3sl4> will have to try the wet-the-drys dry-the-wets breading method, looks awfully effective for not using egg
11:32 <Halcyon> I've mad "craggy bits" before using his "buttermilk in the breading" method. Works well. Also, letting it rest, particularly bigger bits before frying until the white turns moist looking helps ensure maximum stickage
12:06 <T3sl4> the other problem i have is not sticking, say when i use frozen fish fillets
12:13 <T3sl4> but, that's frozen, what do you expect
12:34 <Halcyon> Maybe thaw and pat dry?
12:47 <T3sl4> i had a lovely crust on the last perch i did, but it mostly separated because the bastards curl up so much on cooking
13:49 <Halcyon> Also, if you like green curry, I tried his recipe last week (albeit with chicken thighs) and it was amazing. Soooo much flavour. Probably one of the most surprising ones.
13:59 <Halcyon> I definitely want to try it with fish next time.
14:24 <Halcyon> I'd also double the jalapenos, but that's just me. You can always add chilli flakes/dust after the fact.

28:41 <Halcyon> Agreed
29:55 <jaymax> The "Rage Against the War Machine" event two days ago looked reasonable, but probably only because the news didn't report on it.
30:57 <jaymax> The antiwar appetite is rare, at least in the way for it to be publicly displayed.
31:47 <jaymax> In reality, I think a lot of people are ready to shut politics out of their life if poltics keeps deciding for more war.

44:58 <Ampera> Halcyon, I have a whole duck that's been outstaying its welcome in my freezer. I was going to make it whole, but now I'm gonna chop it up and use it for curry
45:22 <Ampera> I'm using Golden Curry, which is japanese cubes of condensed curry in a box
45:26 <Ampera> idk if they have that there
45:58 <Halcyon> Yeh they do, I love them for a quick curry
46:06 <Halcyon> Or even a dipping sauce for chips/fries
46:09 <Ampera> I think I will do potatoes and mushrooms in it too
46:22 <Ampera> Halcyon, maybe I should make some poutine with them.
46:28 <Ampera> curry poutine
46:31 <Halcyon> With lots of onion
46:46 <Ampera> jaymax is gonna come and eliminate me for liking poutine in a few minutes here
46:55 <Ampera> I blame it on my tainted quebecois blood

47:57 <jaymax> Canadians like to ridicule instead, you soggy fry fuck.

56:16 <Halcyon> That's neat
56:24 <Ampera> it will probably be my regular use iPod after that, because I like the 3rd gen better than the 4th gen pods

57:07 <Halcyon> Aww they gunked down the main IC, boo

58:35 <T3sl4> the last-last apples i got were very sweet and crunchy and tasty, but the sweetness i think was due to sorbitol or etc, they always gave me the runs if i ate more than half of one esp between meals lol
