Glitchy 7-segment 

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

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

Expertise in constructing odd workflows 

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

I really should find the time to learn and use pcbmode ^_^

Consistently amazed at both the quality and design of Boldport's boards. This one is the Capaci-meter.

releasing a J-Link breakout board from 2014 

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~

espressobin, networking, single-board computers 

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

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

particle debugger case, 3d printing 

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

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