The parts remain, but how I got here is undefined, because the code has been lost to time

Back in the system for a SMART re-check and rescrub.. and everything works again, oof

Cleaned things off, and did a dirty re-tinning of a few pads

This stuff and the read errors in multiple spots couldn't possibly be related.. could it?

acetone is magic against cyanoacrylate

..but its a little tricky to apply when your fingers are stuck together

tfw brain interpolates words and fails to send them to your hands. suddenly goes missing

All of this for a simple keyswitch tray (not sure how it should be advertised): https://www.thingiverse.com/thing:3579343

Thingiverse's Customizer doesn't allow outside import of dxf files, so the alternative is to directly embed them in the .scad somehow...

F360 sketch -> DXF export -> Inkscape -> OpenSCAD bezier plugin -> Note size in mm and re-scale 1:1 in px (for reasons) -> Export to OpenSCAD Bezier .scad -> Quickly edit and add linear extrude + variables for customization

in other news, i finally went through 500mL of isopropanol that smelled like vinegar after it was used

oddest thing: transferring a portion of isopropanol with a printed PLA funnel makes it retain a post-evaporation smell similar to vinegar

it seems silly, but this never met the quality bar until recently, when i had to use a J-Link reflash the bootloader on some IoT devices

in other uses of test equipment, giving an AAA NiMH battery constant current so that it shows up in a smart battery charger is new (1.2v at around 0.07A for a minute)

Dream: This extra desk/monitor will let me do all the things!
Reality, months later: Where does all the space go?

i don't know how i made the leap to 'bga reflow is scary' awhile back? the motivation to do my first was a dead phone, and it wasn't bad at all~

globalscale released their espressobin v7 networking oriented SBC with an enclosure option, awhile back http://espressobin.net/announcing-espressobin-v7-revision/

the injection molded case should be a world apart from the printed ones (never got around to designing a SATA cable lid, oops)

finished a printable design for the particle debugger a few days ago: https://www.thingiverse.com/thing:3324087

seeing these at $20 USD is nice; low enough to be accessible to more people
