Teardown 2025: Useful Tools for Your Electronics Workshop

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.

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

@mightyohm finally made me an offer I couldn’t refuse. I’ve known of W6OHM’s Geiger counter kits for years but for various reasons, never actually bought one. 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.

This would be easier if I had the special machine for installing these tab coil bindings.
I was curious about this 5G LTE filter, so I found a set of min loss pads to measure 75 ohm devices. I haven’t done any work at 75 ohms since I designed CATV amplifiers back in the early 2000s. I don’t have an F type cal kit so I did a response cal (thru).
Still new here, what is the deal with Mastodon rate limiting when I try to follow more than a couple people at a time? Super annoying. Is this a consequence of using .social?
