Finally got my single-board-computer working as a USB device!

Now to get the host side working.

And here's a shoutout to the Linux kernel for letting me do almost all of this in user-space!

I'm going to try writing my first IntelliJ IDEA plugin. Wish me luck! 🎉

Oi... it took me all day today (and a chunk of time a few days ago) to narrow down a bug in an app at work to a library we're using.

This was one of the most difficult issues to isolate that I have ever encountered in my admittedly only mid-length career.

I'm kind of proud of it though. Feels like a victory. 🤩

EDIT: wow, somehow I posted entirely the wrong link. Fixed!

Whoa! Imagine you could enhance your print debugging experience with time-saving tools? What if someone made a debugger for your favorite language, but it was based on the print technique instead of stepping? That would totally change my life. =D

“Software you can love”

What an interesting concept for a new brand of free/open software.

Also, I need to look into getting a macro lens. It’s so hard to keep these pictures from coming out blurry.

And maybe clean up my flux too. 😋

It worked! Looks like I can solder 0603 passives without too much trouble. And now I can breadboard with those damn tiny bits too. This little breakout board was half utility and half test/practice. 😃

Oh, and thanks to @AskChip for tips on prepping the boards for soldering. Those green scrubbies are awesome at removing the oxide layer, but not the copper!

I finally got the isolation routing to come out clean! 😃

I just had to measure the imperfections in the tool and adjust the isolation job to compensate. Oi, what a pain, but at least it worked.

Btw, this is a test board for a bunch of 0603 passives I just ordered. Should be good soldering practice too.

On a related note, anyone have a good source for quality CNC tools in the US? 😀

Apparently the ones I bought off the internet are garbage. If I'm lucky, 3 out of the 10 bits will actually be usable for isolation routing.

I bought a CNC mill recently to prototype PCBs with a turnaround time on the order of hours instead of weeks. But I've been having a hell of a time getting the isolation routing to come out clean.

After a long story, it turns out the V-bits I've been using are just poorly machined! Inspection under a microscope shows all kinds of issues. It's so bad I'm tempted to write a blog post about it, if anyone's interested.

Chuck Norris can hand solder a BGA.
With his eyes closed.
Using his feet.
In shoes.
Made of concrete.
Under water.
With a soldering iron heated only by his anger.

🤣

And who says comment threads are all bad?

Seasonal pranks and grammatical imperfections aside, I really like the sentiment of this slogan as a business philosophy.
