<awygle> It falls into a long long list of things that I discovered after having an idea and then googling to see if someone else had already done it
<awygle> I must have found it before I started hanging around here, or even the rust community, or I'd have recognized "whitequark"
<whitequark> huh nice
<whitequark> wanna work on it with me and others?
<awygle> I would like to but probably don't have time

<pie_> well this isnt encouraging for us reversy types lol https://hackaday.com/2017/09/11/the-components-are-inside-the-circuit-board/
<pie_> :|
<pie_> azonenberg? ^
<lain> haha
<pie_> i mean heck whats to stop you from just sticking a tiny wafer in the path of a couple sunk traces
<pie_> or whatever
<lain> that's still horrendously expensive
<pie_> (i havent actualyl finished the article lol)
<lain> this has been a thing for many years
<lain> but nobody does it :3
<pie_> ah
<rqou> yeah, you need to assemble it _before_ laminating the PCB
<rqou> too much work :P
* pie_ mumbles something about implants :D
<lain> :D
<rqou> hmm, now i wonder just how much work laminating a PCB really is
<pie_> might be less practical than alternatives i guess
<rqou> i assume you can't just take sheets of prepreg and feed it into one of those "make your wallet card fancy" laminators
<cr1901_modern> pie_: I could've gone without seeing that link and be much happier
<pie_> lol im sorry D:
<pie_> (though even i found the part about using traces for components as not new)
<rqou> wow, somebody made Nautilus (the file browser) astronomically slower recently
<pie_> ..
<pie_> :|
* pie_ ponders running explorer.exe with wine
<pie_> something something the linux desktop is going to shit?
<rqou> wow gimp is shit

<sn00n> hm, a ice40hx1k has a thick passivation layer, or? the esp32 i decapped for reference has nicer details (esp-ecially the RF section)
<rqou> oh yeah, what's the recommended ghetto nitride etch?
<sn00n> oxygen plasma?
<rqou> that's not exactly trivial to set up, is it?
<sn00n> dunno
<sn00n> didn't tried yet :)
<sn00n> but i mean ... anisotropically should be easy?
pie_ has joined ##openfpga
<sn00n> vakuum pump, reaction vessel, flask of oxygen, RF source?
<sn00n> maybe air is enough?
<sn00n> i mean isotropically, sry
<sn00n> RF source could be magnetron of a microwave oven or an amateur radio transmitter?
<sn00n> to get it cheap and robust .... i mean without the need to build a source from scratch
m_t has joined ##openfpga
<rqou> if you think this is trivial, please help contribute to homecmos at some point
<sn00n> but wet you can use phosphoric acid
<rqou> so i personally think wet etches are easier to ghetto-prepare, but azonenberg hates wet etches
<sn00n> ok, how to contribute? (if it work)
<rqou> i'll get back to you later, it's 3am and i'm rushing to finish a ppt for school
<sn00n> according to "Halbleiterelektronik" (Ruge et al.) cooking in H_3PO_4 (ortho phosphoric acid) will do the job
<sn00n> bye
<rqou> yes, i know phosphoric is the industry standard etch
<sn00n> i would prefer plasma too, it's fancy & shiny :)
<sn00n> ok
<rqou> but that's not super easy to come by

<sn00n> but maybe it's polyimide than oxygene plasma comes handy again
<sn00n> polyimide residues which survived the HNO3

<pakesson> awygle: start by figuring out where you want to go, and then find a conference there
<pakesson> (the answer is ShakaCon)

<pointfree> yea
<digshadow> hmm think I had at least one person, but can't remember if that was you
<digshadow> anyway thanks for heads up
