EE, RF HW engineer doing what I can on the edge of the Milky Way. He/Him

"i'm watching my favorite leslie nielsen movie for his birthday"

"what's that?"

"it's the anniversary of a person's birth, but that's not important right now"

It’s a little know fact that Greyhounds are solar powered.

So, Java dummy here, running on Windows 11. I'm trying to get FidoCadJ up and running, and have downloaded/installed both FidoCadJ and the Java v8.471. When I try to run FidoCadJ on my desktop, I get "A Java Virtual Machine Launcher message "A Java Exception has occurred". What's the next step to get it working? #FidoCadJ
Good rework tip, odd location

my 90 year-old dad died last night after a very long life, a long decline, multiple hospitalisations, and the last couple of months spent in hospital & a repat facility

lots of complex feelings for me, but I’m glad he no longer needs to struggle in difficult circumstances (largely of his own creation, but still ❤️‍🩹)

when he was young, he travelled the world in the Merchant Navy in the loud, hot bellies of large cargo ships amongst the enormous engines with pistons several times taller than himself. he only spent a short time in each port – a tasting menu, you might say – but he felt that he had seen the entire world by the time he got married

he worked many jobs in his long career, most of them spent bending metal to his will, often shaping machines into new forms to perform tasks for which they were never originally designed. he worked long hours to provide financially for his family – which he saw as his main duty in life – but also because he loved working with machines & solving engineering problems born of metal. grease. electricity.

he was a fitter & turner, a boiler-maker, a repairer & maintainer, a “keeper-runnerer”, a tinkerer. he used tools to design & make other tools to make machines. I’m sure that some of my own interests & skills were influenced by growing up watching him execute his craft, hearing him talk about his work, & being dragged along to yet another industrial robot exhibition 😩😜

he was a life-long learner, and my own love of 🤔 – or at least facility with – computers & electronics & code (oh my!) were things he saw (and understood) and supported. in the late 1970s or very early 1980s he took a programming course (which was the spelling at the time 😜) at the local TAFE, and he took me along – a rare opportunity in that era. my first hands-on experience with code at 11 or 12 years old was in the form of mapping out & writing programmes down by hand on graph paper & then encoding them on a stack of mark sense cards with a B2 pencil to be fed into a card reader (and drawing that all-important diagonal line down the side of the stack with said pencil – #IYKYK 😆)

it wasn’t long until I had begged sufficiently & got my very first computer (that we absolutely couldn’t really afford), a #CoCo – the original #TRS80 #ColorComputer model in “battleship grey” with 16K RAM 😲, later upgraded to a whopping 64K 🤯 🤯

I still have that computer over 40 years later 😊

after he retired, he always had several ambitious plans on the boil (less charitable folks might call them “hare-brained schemes” 🙃), including a petrol-powered all-terrain tracked wheelchair for a friend who wanted to be able to travel off the beaten path under his own (metaphorical) steam. it would have ended up weighing about a tonne & absolutely would never have worked (safely), but he was determined to “help” a friend & excited to work on solving an interesting engineering challenge, once again bending metal and machinery to his purpose du jour

he was happiest noodling in his workshop, oil- & grease-stained hands deep inside a machine, wielding – or welding – a new tool of his own design. I always associated the smell of machines and ozone with his presence. until after he retired I never saw his hands unstained by years of ingrained, immovable grease

in his later years he discovered #3Dprinting and became a journeyman #maker of sorts. he was exceptionally proud (and a bit obnoxious) when he was able to “teach the professionals at #U3A a thing or two” about his new hobby. his idea of a conversation had always been (impatiently) waiting for you to take a breath so he could tell you the next thing he was interested in – usually unconnected to whatever you’d shared 💁‍♀️

he used a succession of smallish 3D printers to make many, many Japanese-inspired lanterns (into which he stuffed various strings of coloured flashing lights) and Chinese-inspired dragons, amazed & delighted that additive manufacturing was able to create interlocking objects right off the print bed – after having spent a lifetime creating sometimes-intricate interlocking components using tried-and-true subtractive manufacturing processes. he gave most of these prints away to others – whether they wanted them or not 😆

he was a fitter & turner, a boiler-maker, a repairer & maintainer, a “keeper-runnerer”, a tinkerer

and he was my father

It’s always a good day when a jetpens order arrives. Some Zebra Sarasa nano’s, Zebra Sarasa R’s, and some JuiceUp’s and a couple of Uni-Ones, along with a Jetstream light 😀
New blog post - Physics-Defying Marketing: Review of a Misleading Vendor Article, and a VNA Calibration Primer https://niconiconi.neocities.org/tech-notes/review-of-a-misleading-vendor-article-on-vna-calibration/ Beyond exposing misleading marketing claims, this article also serves as a primer of VNA calibration and the existing literature on coaxial parasitics calculations (I showed five methods in appendices). The screenshot is my favorite part. #electronics
Well, I just got laid off from my job. If anyone needs a talented embedded systems engineer or hardware engineer with strong experience in video hardware, send me a message with details of a job opening and I can provide a CV. Remote work preferred, but I can work anywhere in central Minnesota. Boosts welcome and encouraged.
