awygle: No, I've never tried PCB design. I have tried soldering, though, and the results are ... rarely anything to be proud of

ah. well pcb design is fun! i recommend trying it :)
<awygle>
or alternately, hire me

PCB design is a lot more fun than soldering
<SolraBizna>
One of those things has undo
<Bob_Dole>
soldering?
<SolraBizna>
if you cook an IC, you can't undo that >_>
<awygle>
one of them requires steady hands :/
<SolraBizna>
unsteady hands buddies!

highfives awygle

's hand shakes, causes highfive to miss
<Bob_Dole>
I don't have steady hands which is why I want to oven BGAs and not touch big QFN/QFPs
<Bob_Dole>
and have stencils
<Bob_Dole>
and try to do 0805 caps and MAYBE the next step down if necessary but NOT the step under that.
<SolraBizna>
then why the devil did you sell me on a QFP SRAM!?
<SolraBizna>
you've got me putting six of these on the board
<Bob_Dole>
they're a wide pin one right?
<SolraBizna>
0.65mm lead pitch
<SolraBizna>
the other QFPs I've seen were 0.5mm
<Bob_Dole>
I think I've done .5 successfully so with a stencil I can tolerate that
<Bob_Dole>
.5 with drag-solder*
<Bob_Dole>
also: because of cost. the bgas were a little worse dollar/bit for some reason
<gruetzkopf>
soldering has undo
<gruetzkopf>
0.65 is fine
<awygle>
i honestly don't find QFPs that difficult
<gruetzkopf>
flux.
<gruetzkopf>
use more flux
<awygle>
flux+drag
<Bob_Dole>
with this much SRAM I am interested in mining performance on cryptonight, if an ice40hx8k and a couple MB of sram on it, since a single thread only needs 2MB of memory. >>>
<awygle>
just don't put them on the bottom of the board is all
<gruetzkopf>
i it were feasible to submerge boards in flux during manual soldering i'd do it
<reportingsjr>
hahaha
<awygle>
isn't that just vapor phase soldering
<SolraBizna>
all the copper in my apartment corroded just from thinking about that
<Bob_Dole>
particularly, if a "complete" rv32 core without custom bitstream for the algo can do it
<gruetzkopf>
then again i do 0402 smd for fun
<gruetzkopf>
it's simple, and kinda relaxing
<awygle>
i mean
<awygle>
no kinkshaming
<awygle>
but that's definitely not my jam
<SolraBizna>
...so I was stressing out about how to implement writing to the counter registers
<SolraBizna>
and it inflated my core by 50%
<SolraBizna>
turns out they're supposed to be read only
<Bob_Dole>
though, if the best dollar/bit ratio was in QFN, I would go for the worse dollar/bit package that wasn't QFN
* SolraBizna
headdesks
<awygle>
agreed that QFN is the worst

bad ideas: lisp-type system running directly from flash memory, leveraging immutability and copying garbage collection

sounds similar to the ROM-resident resource maps in old Macs
