The slides for the talk I gave at Teardown 2025 are posted here. I’ll post a link to the video once it’s posted online.

. @Icchan I agree. We need a vault for social media content so that it can be archived and made available independent of the originating platform.

I wish there was a good way to archive/transfer old conversation from defunct and abandoned social media sites to new platforms.

Regardless of the BS and filth these older platforms degraded into before decent people started to abandon them, there was really good, highly educational and informational content on them written by industry professionals and that content would be very relevant and useful even today.

One example is this imgurl post I did as a "response" to a topic about electrolytic capacitors in consumer electronics, how they have a shelf life and limited lifetime when assembled into a product, but they will take down the product when they ultimately expire...

This post refers to a twitter thread by @mightyohm but he's since removed his twitter account and all the threads and conversations went with it...

I support whole heartedly his decision, but with it. among with others that have done the same, tons of very good conversations and information is now gone...

It's a bit of a shame really and could be a springboard to a conversation about broader topic of "will internet die because information is constantly removed or lost from it and the linking that was supposed to make internet amazing will break?"

What's the role of the companies running these services and vaults of vast amounts of information?

Could be, maybe, get back to the era of personal websites and forums that are as numerous and spread around as they used to be?

Mastodon surely is part of this movement... but we still do not know what we've lost forever and what will spring up again in this vast sea of information and exchange that we call the internet.

This thought has same questions bound to it that Ghost in the Shell franchise asks about (I do NOT regard that Hollywood atrocity as part of the franchise)

If you haven't yet seen the Ghost in the Shell movie from the 90's or other media regarding it, I can recommend them as great works of art.

Anyway, I'll stop rambling now :D

Now he made it too tempting not to. https://mightyohm.com/blog/2023/10/spooky-sale-geiger-counter-kits-are-on-sale-for-just-99-95-at-amazon-com/ Will mention this in Zero Retries this week.

@osterwood trigger light is probably a self cal issue. Don’t know about the other one. I wouldn’t worry too much until you run through the quick cal steps. Recap the PSU as soon as possible. It’s a confusing instrument to use so you’ll have to spend some time reading the manual.
@osterwood definitely recap the PSU. There’s info on eevblog. Guaranteed that there are leaking caps, they all fail. Both of mine needed a lot of work. These often fail self test until you perform the gain/offset cal (easy to do but you need a precision 5v ref).
@nanographs I didn't realize they were special. I have three of them, all working to some extent. 😀
@nanographs Does your 603 storage function work? It's wonky on mine. I'm not sure if it's an adjustment issue or a fault of some kind. The manual warns of ions being trapped in the CRT affecting CRT life which has me nervous.
