finding notes inside your electronics explaining various errata and providing usage info and warnings?

we can't overstate how much this rules?
this rules

probably our most radical elecronics take tbh:
comment your hecking code

Show thread

how to absolutely whip ass:
put a little pocket inside the device's outer cover, and put a little leaflet in there with various important servicing notes. explain what the LEDs mean. say what the headers are for, and what the switches do. all of that, right in the actual device.

Show thread

hecko bonus round: indicate potential failure modes. helpfully indicate which parts might fail first due to wear, or reversed power supply polarity, or a voltage spike, or any other likely accident, so that diagnosis and repair can be considerably expedited.
(also, test points!)

@diodelass my god, it’s like the good bit of 1960s electronics

@diodelass I appreciate their use of will in "will cause damage" as opposed to the more wishy-washy "may cause damage" we often see

@diodelass extra bonus: include schematic, block diagram and test point reference value table.

@sophistoche yes, absolutely 100%

our father has a little line amp with his sound equipment that has a block diagram printed on the outside of the case, and that also extremely rules

that diagram was how we learned how phantom power works!

@diodelass phantom power is super cool and magic. Until someone enables it on something not expecting it and you get to hear the death throes of the electronics through the line

@djsundog @diodelass not yet, that would include spares of the most likely components to fail as well, surely

@diodelass that's amazing but now I'm scared to touch the battery or red/black cables and I guess I need better reading comprehension

@wilbr don't worry, we are too. this device is delightfully chaotic.


the vendor was -expecting- you to open it up? @.@ *boggle*

@banjofox yep! that's pine64 for you. we suspect the number of people who have one of these (so far, only the first ~1000 have shipped) and have not opened it up is rather slim. they even published instructions on how to do it properly on the forum.


I will be getting one when my laptop finally dies.

its... an 11 year old Toshiba, and being held together wiht packing tape.

Pretty sure it is unkillable at this point LOL

@diodelass A lot of electronic devices have so little space to put a piece of note inside. I'm currently fixing a Mac that needs to have a signal shorted out and I'd like to note that. But there's no space for note.

What should I do? Microfilms? 🤣

@diodelass That's a bit how electronics used to be decades ago :_)
Esp. with high end equipment. You *owned* your device, and therefore had all you needed to service or modify it.

@diodelass I hope that note was sticked down. I'd hate a loose piece of paper slide over the SoC and make it overheat or even catch fire. 😜

@diodelass oh that is wild! Mine arrived today and I should have a look inside.

@diodelass great they put the notice in, unhappy about the design...

@saper is what it is. power supplies are hard.
folks had to sit there and solder these wires onto every single unit in this batch to make this possible.

@diodelass oh that was manufactured by hand? ouch. I did try to reverse engineer firmware of an embedded controller of my laptop and I couldn't wrap my head around those issues (I'm bad at electronics)

@saper much of the process was by machines, but at least the attachment of the battery bypass cables (which we assumed you were referring to? that's what the sticker is explaining) was clearly done by a hand.
and... we're suspicious of how shiny the solder is. hope it's not lead...

@diodelass I bought an EkoSynth P15 in 1984, for £150 .. all my savings at the time

When I took it to pieces it had a full circuit diagram inside.

Best that.
