I silly-promised work I would dress “appropriately sciencey” for today’s awards ceremony. I forgot I had bought this blouse before the pandemic, but once I found it in the closet, I knew what had to be done. #BoldlyGo
I had discovered the magic of dialing "atdt *67," before my local BBS, which disabled Call Waiting, allowing me to send all my mother's random junk callers to a busy signal - much to her dismay. That was incentive enough for her to finally get me a "teen line" of my own and then I was UNSTOPPABLE!

I started at 2400 and I just remember how awesome it was to be on that first T1 line. Zoom!

Once in a while, my brain has a “record scratch” moment when I remember how crazy fast 1.544Mbps was… as I’m measuring my current network in literal *hundreds* of Tbps.
I then slowly reboot, with all the 5.25” drive clunking of an Apple ][

Illinois respects the sovereignty and borders of Ukraine — now and always.
Three years ago, Russia invaded Ukraine without warning or provocation. Peace and freedom requires resistance to tyranny and oppression.
Slava Ukraini!

My Electronics I professor, way back in 2000, once said (after his math came out wrong by a few volts): “In science, an order of magnitude is usually good enough.”

Sometimes, you just have to walk over to your supercomputer and rip a power cord out to remind it who’s the boss.
Take that, switch x6101c0r47b0! You will forward packets, and that’s an order!

We did a lot of labs that crossed into frequencies in the “longwave” region and I recall the lm358 because it was good for such a wide bandwidth right up to about a MHz. Been so long since I played with wibbly waves in their analog form though 😰

Gotta love the LM358 💕 I may have accidentally turned a couple of those into magic smoke in the lab back in school… 🤪

here's the schematic, it's exactly the same as the model 1's onboard design, just duplicates it for each channel instead of mixing them down to mono.
whole thing fits comfortably into a 23mm x 13mm (0.9in x 0.5in) board if you can do smt soldering.
i can't offer tech support, but have fun 💜

That teacher had been unfair before, and claiming I used foul language was pretty serious, so my parents demanded a private meeting with the principal…
My mother insists my father didn’t raise his voice, but suffice it to say, the school administrators were always kind to me after that incident.

In 5th grade, I told a kid who insulted me to “shut your big ugly mouth!” My teacher somehow heard “… big fucking mouth!” I was immediately suspended from school for a day and banned from performing in the choral show that week.
