Trying to find my people on here. Please share and follow me if you:

-Believe the lava from lava lamps must be returned to volcanoes, where it rightfully belongs.

-Argue that marathon runners should shave their eyebrows to be a little faster.

-Will eat the rich on principle, but dread the taste.

Finally soldered and glued up @tomnardi 's Bus Pirate SAO this afternoon. LEDs are pretty, haven't tried the GPIO expander part yet. Thanks for handing me the kit at Supercon.

This is an experiment. Please boost.

Here's the idea: This post is going first to my followers, then, if they boost it, to other people. This domain has been registered for only this experiment. I should see in my web server's logs when mastodon instances start crawling the site for info. Then maybe also some curious humans.

I just want to play with my monitoring a bit :)

Let me share with you a narrative of a software bug I just fixed in an all-night session (while still fresh in my mind).

You can see the problem in this video demo, starting at 1:26.

A deep dive will take several messages, so buckle up...

Your irregular reminder that #Linux signal numbers are different on different architectures. So signal 10 is SIGUSR1 on ARM/x64 and SIGBUS on MIPS and you get mighty confused interpreting a core file when you pick the wrong one.

See https://man7.org/linux/man-pages/man7/signal.7.html for a handy table.

It was great to meet @mitten in the food line at #SuperCon on Saturday. Her hedgehog SAO was quite adorable in person, and she was so nice!
If you can't figure out why your #Arduino test code isn't working in a sane way, remember that any local variable declared in your loop() function will be reinitialized over and over, since the loop that calls loop() is at a higher level. I spent way too long earlier today debugging some touch button management code until I had that "duh!" realization.
I have been working on a felt SAO for the Hackaday contest, and I think I’m almost done. I’ve been posting project logs over there, and this is the latest one: https://hackaday.io/project/198398-fuzzy-sao/log/233889-much-closer
I’m pretty sure I can get the final one done in time to submit it - I hope, anyway!

<p>I've resewn and connected the 5 LEDs, moving them over to the right significantly.</p><figure><img data-src="https://cdn.hackaday.io/images/6897781729549516890.jpeg" class="lazy"></figure><p>I had to move the wires around to make this work better, and they're a little worse for the wear, but are still solid enough to light up the LEDs.</p><p>Much better placement...</p><figure><img data-src="https://cdn.hackaday.io/images/7188301729549595671.jpeg" class="lazy"></figure><p>This is without any diffusion, and the felt just sitting on top, but you get the idea.</p><p>And adding the diffusion fluff and sewing it together...</p><figure><img data-src="https://cdn.hackaday.io/images/2742041729549653920.jpeg" class="lazy"></figure><p>Kind of hard to see the glow on this sunny afternoon, but it's much closer to what I was thinking.</p><p>Now I just need to reformat the design a little bit. I need to take out some details - they're too small to render in felt. And my intent was to have the "spikes" on the front piece and the back piece offset each other to give it a little layering dimension - but that's going to take a bit more precision in my cutting than I applied to this version. And I just used a sharpie to make eyes, but I'll probably embroider them for the final piece.</p>

My latest project is something for prototyping something good. https://hackaday.io/project/198297-breadboard-sao #electronics #Hackaday
Breadboard SAO

This is a useful method for hacking out a quick Simple Add-on. Take a super cheap mini-breadboard, directly solder a surface-mount 2x3 SAO connector to the bus pins, cover in Kapton tape, and prototype away.

Here's my badge #SAO for this year's #HackadaySupercon
It has a few button selectable modes, but the default one follows the state of the characters in Pac-Man 's attract mode.

It's also commandable over I2C, so you can set the LEDs up yourself if you like.

Thanks to @simenzhor for the help around the obscure but cheap microcontroller.

I will have some at Supercon and may throw some up on Tindie.
