I discovered this strange character on Youtube. A brilliant pianist but something of a nutcase. It amused me.

How big is a neutrino?
Well, probably not what one would expect.

These came up in my search results while I was trying to figure out how to get my X-Arcade's trackball working in a RetroPie build... lots of horror-show content; grab a cup of coffee and relax, kill a few minutes. For the record, I don't give a flying fuck how much moo-sqweezins you may or may not have in there.

Add a soupcon of chlorine, and...
"[ClF3, chorine trifluoride] is apparently about the most vigorous fluorinating agent known, and is much more difficult to handle than fluorine gas."
"I’ll let the late John Clark describe the stuff, since he had first-hand experience in attempts to use it as rocket fuel. From his out-of-print classic Ignition! we have:
”It is, of course, extremely toxic, but that's the least of the problem. It is hypergolic with every known fuel, and so rapidly hypergolic that no ignition delay has ever been measured. It is also hypergolic with such things as cloth, wood, and test engineers, not to mention asbestos, sand, and water-with which it reacts explosively. It can be kept in some of the ordinary structural metals-steel, copper, aluminium, etc.-because of the formation of a thin film of insoluble metal fluoride which protects the bulk of the metal, just as the invisible coat of oxide on aluminium keeps it from burning up in the atmosphere. If, however, this coat is melted or scrubbed off, and has no chance to reform, the operator is confronted with the problem of coping with a metal-fluorine fire. For dealing with this situation, I have always recommended a good pair of running shoes.”

The story of Heathkit
A Youtube video 21:45 minutes long on the origins and end of Heathkit. I'm sure we've all built, or acquired at some stage, Heathkit gear.
10:30 to 16:40 is a quiz type presentation, which I found I could do without.

While bumbling around looking for a picture of a hand card punch, I came across

Short videos of what there is at TNMoC, plus other stuff. Looks like it is a KS2/3 teacher's resource.

There's a hand punch available at the CHM in Mountain View. I've operated it. The card I'd punched was then verified by running it through a Model 26 Printing Card Punch in copy mode.

From tekscopes, news of Sphere's HP and Tek inventory....

As many may remember, Walter Shawlee II passed away September of 2023. Since that time, his wife Susan, and children, have been busying themselves with the task of liquidating much of the electronic goodness that Sphere Research had accumulated. Susan intends to continue to make their collection of slide rules, nixie tubes and various other items available. Additionally, she is continuing in her effort to find homes for the remaining equipment. Please do visit Sphere’s site and help.
Sphere’s inventory of Tektronix and HP parts has found a new home with us. We have the beginnings of a website (tekandhpparts.com), with the intention of continuing to make these parts available to the Tek and HP enthusiast community.
A bit about us:
1) The goal of the website is to continue to make Sphere’s inventory available to the people like us that enjoy collecting, repairing and making use of these amazing examples of engineering and manufacturing.
2) A secondary goal is to “pay back” our retirement account of the funds used to buy the parts. It is truly secondary, and may never happen, but who knows?
3) We are retired, have three children, farm 20 acres of grass hay, tend to cows, sheep, horses and chickens, and have FAR too many hobbies and other responsibilities to have taken on another, but here we are….
4) Our website is an amateur work in progress. Please read the home page posts for information on the site and on our progress. Tek items will be posted first, followed by HP and then “other” semiconductors and who knows what else. There is much awaiting inventorying, so if you don’t see the part you are interested in, please contact us directly (tom@tekandhpparts.com) and we will let you know if we have it. Look for announcements on the homepage as we complete the inventorying and pricing of each group of parts. Please be patient as we get the website, inventory and pricing figured out. Feedback is, as they say, a gift, so please share any constructive advice or suggestions for the site that you may have. The suggestion "You should have your head examined" has already been given!
We can’t ever hope to duplicate the knowledge that Walter possessed, but will do our best to provide you with the right parts for your project. We look forward to getting to know our new customers, and will work hard to earn your trust.
Thank you,
Tom and Darla Norman
