yeah look, if I hear of any, I'll tell them how good a coffee you make

NB: this simple form pulse output is limited to min 31 Hz. Prob have to re-write the Arduino library...

(sucks teeth) yeah, that's gonna cost coffee and lamingtons. As a brofessional firmware engineer, I gotta say: have you considered brass gears?

Oh, 4" CRT for your vector line drawing needs! https://vi.aliexpress.com/item/1005001892618952.html Someone (cough, @Roman) should totally do a period looking ECU display on one of these!

Alas, now me also, but only for the shares with passwords. The non-password public dir is a closed book to this crown-jewel of crapitalism.

Sooo, I'm now having related fun with my new Win11 install: https://techcommunity.microsoft.com/blog/filecab/accessing-a-third-party-nas-with-smb-in-windows-11-24h2-may-fail/4154300 TLDR: M$ turned off an old sharing thing, and broke many many systems shares. Steps 1 - 5 are: IT'S EVERYONE ELSE'S JOB TO FIX THE THING WE BROKE Steps 6 on are WELL OK, BUT IT'S NO CARE AND NO RESPONSIBILITY Naturally none of steps 5-6, nor 8. to 8.e have fixed it.

Installing new ram in new-old PC with tin-snips...

Oh, and i farted out an (crude) animation system for that LED. if only I could figure out how to make a 2.5MB video work in this page Indic3x3 test1 crop(1).mp4

Once upon a time, baby-engineer H4nd was at polytech, and we were making PCBs for flashing LED circuits (Tape and Donuts!). I said, errr: I've been playing with some Audio circuits, Can I make that instead: Add a few scraps from 200A soft starters, and presto: still in service. I refreshed the caps with new cheap low ESR, and it's bumped the bass response a bit, didn't expect that!

3:50, wide range in EGT

Is this the engine noise enablers thread?

Gah: there goes my plausible deniability for interfering with his data, should I ever wander past his for a cuppa!

I had some code that just wasn't playing well. It was interrupt code running in someone else's environment (Arduino), so that's just about par for the course. I spent all night and failed. Today, I had a fresh look and figured out it was problems interfering with each other that made it intermittent and really hard to diagnose: Arduino Due doesn't use the usual way to assign whatever interrupt # is assigned to a pin, like this: // BUG: BROKEN ISR ALLOCATION STYLE //attachInterrupt(digitalPinToInterrupt(63), ctIsr0, FALLING); nope, you just bang it in there, thusly: attachInterrupt(63, ctIsr1, FALLING); Ok, fine fine, there was random interrupts going off without service routines, no wonder it was jittery and crashing. and an obscure bug: on a Due, if you later on change the pinMode(), any attached interrupt detaches bug report here https://github.com/arduino/Arduino/issues/1693 which got closed and moved to here https://github.com/arduino/ArduinoCore-sam/issues/26 which is still open! Also, I'd had a problem with a Due board and terminal PCB, so I moved to the spare I bought for the job: The SPARE had broken pin 63 (NB above) and another broken pin I happened to be using as an output for testing timing. (!!) then, to add insult to injury, my main scope probe had come loose at the tip, resulting in intermittent connections. (!!!) Yeah, last night was doomed.

Maybe I don't treat windows very well, it seems a bit upset:

Also: YouTube malware/scam ads are getting pretty brazen Capitalism ruins everything

Another new windows enshittification: Ads on the lock screen, and you have to click one to get to the login text box (which then opens EDGE to that ad as you login). Middy is getting Linux.

I needed a 10% random signal at about 100Hz (average count about 10 per second) void setup() { } void loop() { digitalWrite(LED_BUILTIN , !random(9)); delay(10); } Job done.

..."Office 365 autosave only works to OneDrive shares now, not local storage" W T A F ??!?!!?

When I was last looking at some EFI manuals, they were at pains to point out not to share the battery cable for the ECU (because when starters, fuel pumps, fans pull current, and Alternator pushes current, the grounds change V a little because passing current through a connection with some resistance. All those are choppy and can have short but vicious V spikes that are tricky to measure without an oscilloscope, but can def cause issues). For some sensitive inputs, this can cause subtle and annoying problems. I seem to remember they recommended running the ECU wires separately to the battery, and that'll be even more important with the remote mounted battery. Best check your EFI manual! Hope daughter is doing better.

Not everything's a project? Really?

Much easier if we can see the housing, and measure the housing inter-pin pitch

I burped this out on Sunday 5th. USD$24 using a $6 first timer voucher! (NZD$41) fro 150 x 150mm. Oh! that hit Aucks on Thurs 8th using the cheap 11-15 days shipping, is in town today!

What's better than 1W dome LEDs? Why, arrays of them as status indicators. I'll be able to show daylight visible cross, square,circle, and spinning line animations etc.
