ok, pretty happy with this now. Added a lot more filtering caps to try to reduce the noise and flicker, improved grounding (at least as best as you can on a breadboard) and tweaked the magnetic and electric focus a bunch more. I'm very happy with the result now!
For those wondering about the setup:
DIY HV is supply supplying 700V which is divided down for all the different electrodes in the vidicon tube, 600V on G5, 300V on G4 and G2, 65V on G3 for focus, -35V on G1 for beam current. 15V on the target. Raster is generated by 2 555 timers set up as ramp generators and amplified/centered by two opamps. Output from the tube is amplified by a transimpedance amplifier, amplified again and then output straight to the Z input of the oscilloscope. There is no blanking during either vertical or horizontal retrace, neither on the vidicon nor output, which is less than ideal but works. Vertical frequency is around 40hz, horizontal around 10khz.
I get a fundraising email stating "We have only 3 days to raise $24,456 so we can have the funds to launch our campaign properly [...]"
Where do they get this oddly specific number? What are the odds of winning if you don't get it vs the odds if you do? Is there an inflection point?
If you go to donate: "Make it monthly?" (they ask this TWICE) "Leave a tip?" You're asking for money to cover processing, that is not a "tip". They "suggest" 16%: that's a big processing fee.

The bitter irony in the current GOP infighting over whether Americans are competent enough to become tech workers is that numerous LGBT tech people who are frantically emigrating over hate were committing time to train people to get those jobs, often for free. My best friend wrote a whole book.
Yo, music services*: if you won't let me BUY the track I want, I'll pirate it or do without. I am NOT paying for a subscription, FYVM.
* software publishers too
I've forgotten the term for the twisted splash of light effect made by bouncing off a flexible mirror (visible in the original Battlestar Galactica intro, and the "edge of the galaxy" effect in unremastered Star Trek:TOS)

Continuing on the MacOS diskimagesiod vs youtube battle, it occurred to me I could update the plist for diskimagesiod to say the ProcessType is "Background" - the launchd man page says these should not distrupt the user experience. This involved a few reboots and arcane commands to allow me to edit a system file. However, it didn't work.
It turns out that when ComCrap says "at no additional cost", it's like the "free" home security systems scammers sell: there's a monthly charge...
Updated to the latest Sequoia 15.2. Still has the bug where if you're backing up to a NAS, every so often diskimagesiod suddenly eats all the CPUs and causes youtube to stutter and freeze.

I've started feeling kinda bad for all my knobless old boat anchor equipment being reduced to a place to harvest cool metal knobs for projects. So I've taken matters into my own fingers.

I keep forgetting this isn't Twitter and external links won't effectively hide this post. So here's a @crowdsupply update where I talk about the rationale behind this.

@alpenglow As a matter of fact, it does say that.

I teach my law students that law’s most important purpose to address anger, where possible, in a socially functional way. The social media reaction to a cold blooded first degree murder suggests laws governing health care are not performing that task adequately.
I dreamed my sweetie was showing me a new basically pointless meme that was just pictures of puddles with the text: "WET: The Strong Stay Away". So when I woke up, I made one. Enjoy?
Filled out a survey and was offered a gift card or donation as a reward. When I tried to make a donation, it required an email address! I don't want more requests for money, I'm just trying to do a nice thing!
Saw an ad for a prostate cancer medication, that warned it could have effects on pregnancy. Um wat?
One of my tractor tires was leaking through the valve stem. I didn't have a core removal tool, and the only places that did were a fair drive away. So I just made one.
These advertisers really want me to open their mail. The die cut extension made to look like a post-it note is a little over the top.
I got a spam email claiming a payment problem with Disney. It had a link that redirected to an AWS site that redirected again. I tried to report it to Amazon, but their form has a box for "Complete email header and body", but then rejects it "We have identified that your submission may contain potentially malicious content." It's a waste of time anyway, as Amazon doesn't care if their money comes from scammers, as long as it keeps coming in.
