I built a couple of 60% and one split (redox), though I messed up the redox somewhere and only one side of it works
<ocb>
jaeger: oh, so im not very demential after all
<ocb>
sorry for the hl
<ocb>
spilled my keyboard today after 7 years of using it, appears to be burned
<ocb>
never built my keyboard, but might take a chance now due to situation
<ocb>
wanted to ask you, what place do you order parts from, do you recommend giving alibaba a try?
<ocb>
looking to build a 65% :)
<jaeger>
Sorry, got distracted for a bit with my work laptop crashing repeatedly :(
<jaeger>
I have used parts from aliexpress, banggood, drop, and amazon. I didn't have any problems with the parts from aliexpress or banggood, just had to wait a while to receive them in the US
<ocb>
no worries, hope your laptop will get better and heal himself :)
<jaeger>
I've requested a replacement just now... because this is an old problem but before today I could just ignore it :/
<ocb>
thanks for the information, found some good deals on aliexpress will probably go with them.
<ocb>
^^ what's the issue?
<jaeger>
It used to crash and reboot a few times on login, then once I got past that it would work fine... today, it has crashed 6 times already (not even kidding) while doing normal work
<jaeger>
Just hear the fan ramp up to 100%, screen goes blank, then reboot
<jaeger>
No problem, I look forward to hearing what you think of the keyboard build. I'm not familiar with the available options for 65% but I'm still using both my 60% keyboards regularly
<ocb>
huh, could not ignore such issues with the laptop at all. it must work as designed. what brand is it?
<jaeger>
It's an apple macbook pro... though all the work I do could be done on any kind of laptop
<jaeger>
Most of it is remote via SSH or similar
<jaeger>
Any local tasks I need (coding, VM, etc.) are not OS-specific
<ocb>
will keep in mind to let you know once built :)
<jaeger>
cool
<ocb>
hopefully they'll replace it without issue. never owned an apple device, but heard phones can have some weird quirks. first time i hear about laptop issues that are hardware.
<ocb>
owned a 80% until now, a filco majestouch 80% quite happy but its time to move to something smaller and easier to modify (no soldering)
<ocb>
thanks for the help
<jaeger>
I think this one stems from USB and power delivery somehow because I can exacerbate it by plugging/unplugging USB devices sometimes
<jaeger>
No problem :)
<jaeger>
I have a problem with one of my 60% keyboards I'm not sure how to diagnose... it has LEDs on each key and a hotkey (QMK firmware) to turn them on/off and change brightness
<jaeger>
That used to work fine but now they cannot be adjusted or turned off, always on at full brightness
<ocb>
i have no experience , but anything to do with firmware maybe?
<jaeger>
Not sure how to diagnose that. I'm comfortable with a multimeter but I don't know what would cause it... a short, a resistance issue, etc.?
<jaeger>
Nah, not firmware, reflashing it doesn't help and all other functions work fine
<ocb>
not competent enough, will see when the time comes how all of it works :)
<jaeger>
:)
<ocb>
neigbours came back home, killing the internet .. slow as hell. will go for a walk.
<ocb>
neigbours are 240m away, catching their wlan with mikrotik sxt lite 2
<ocb>
so when they come back from work, and turn on their phones.. AP likes them more :(
<ocb>
have fun and enjoy the day, good luck with apple.. uhmm laptop :)
<jaeger>
Thanks. Take care

jaeger: when you have weird issues like that it's a good idea to check how the electrical signals behave. that's beyond what a multimeter can do typically.
<braewoods>
jaeger: you can check how voltage behaves but may be better to use an oscilloscope
<jaeger>
makes sense
<braewoods>
oscilloscope can visualize the signals to get a better idea of what's going on.
<jaeger>
I don't have one, though I'm sure I know someone around who does
<braewoods>
there's some rather affordable ones but they have a limit. can't handle signals beyond 1 or 2 megahertz i believe.
<braewoods>
dso150 from jyetech but probably better options
<braewoods>
i have one, mostly it's a beginner's oscilloscope. but might be good enough for a keyboard.
<jaeger>
I'll give it a look, thanks
<braewoods>
but uh for LED backlights, voltage checking might be good enough since it should use a regular DC signal.
<braewoods>
LEDs can be controlled by manipulating voltage and/or current
<jaeger>
I think that the voltage is ok because all the LEDs are on... I'm guessing the controller itself or maybe some path between the controller and the LEDs is an issue... because I can't adjust their brightness or turn them off, but they all do light
<braewoods>
that could mean the power control circuitry that causes the brightness to vary is not working properly
<jaeger>
yeah
<braewoods>
perhaps a bad chip
<ocb>
never used an oscilloscope
<ocb>
when you see how a signal behaves, according to what specification do you look how it should behave?
<braewoods>
it's a necessary tool if you're investigating low level electronic problems.
<ocb>
i mean how do you compare how it is behaving to how it should behave, shouldn't all keys send different signals?
<braewoods>
depends. one use is to visualize AC waveforms to check how pure of a sine wave it is.
<ocb>
aham
<braewoods>
ocb: erm, from what i understand of keyboards, keyboard signals are extremely simple. just shorting pins.
<braewoods>
which is a constant high or low signal. a flat line.
<braewoods>
or mostly flat line. there may be some noise.
<ocb>
i see, thanks for explanation. will visit a friend on friday and play with an oscilloscope there with my broken keyboard :)
<braewoods>
it varies heavily. an oscilloscope just visualizes the electric signal.
<braewoods>
if it isn't behaving as expected, it helps narrow down what to try.
<braewoods>
but most electric signals are flat, maybe with ups and downs where the signal is flipping states.
<braewoods>
you should watch repair videos where these are used if you want to get a better idea of what you can encoutner
<ocb>
thanks for the recommendation
<braewoods>
but i usually just use them for checking AC waveforms.
<ocb>
will visit this friend, he fixes hardware and think he'll explain it easier for me in my language and plain terms :)
