I've received a lot of questions about my various open source projects, status of them, etc. Made a public google doc with everything: docs.google.com/spreadsheets…

I've mostly migrated over to Mastodon and am not posting here much anymore, so if you're not already following me there you probably should be! Here's a recent screenshot of ngscopeclient as a sneak peek of what I've been up to.

If @XylaFoxlin puts a bunch of her favorite epoxy in a plastic tote bin... Does that make it a Botal Tote?

Before Twitter, there was IRC. When Twitter is gone, IRC will still be here to dance on its smoldering remains. When humanity has gone extinct, cockroaches will still be using IRC.

Starting to transition things over there as an experiment. Will be posting about a bunch of AKL-AV1 bringup etc. Not abandoning this account yet, but we'll see how things go.

Set up a Mastodon at @azonenberg@ioc.exchange. Not much there yet but feel free to give me a follow!

Well, I'm still here (for now). Made accounts on three different Mastodon instances; two are awaiting admin review and one is having trouble sending me email verifications. Probably all overloaded with rats fleeing the sinking ship.

(Side note: How long until tweets containing "mastodon" are flagged as violating twitter rules? Freenode tried that with channels that moved to Libera...)

Making good progress on the protocol analyzer in ngscopeclient! You can now select packet contents to be displayed as ASCII, hex, or ascii+hex dump. I might want to make the data field collapsible? Not yet sure how best to handle large packets.

This is still a WIP: most notably, the very nice integration glscopeclient had between the protocol analyzer, waveform views, and cursors (click a packet to jump to it, packet under cursor is highlighted in analyzer) is not yet implemented here.

Calling all internet aerospace historians: When I was a kid, my dad had a set of vinyl records (pretty sure 33RPM LP) containing a narrated history of the US space program. It included discussion and radio clips of the Apollo 11 moon landing so was 1969 or later.

I think it may have been produced in collaboration with some major media studio, radio/TV network, etc but can't recall specifics. The main narrator was pretty well known, perhaps Cronkite? Anybody able to find more details on what this might have been?

(He probably still has these sitting on a shelf in deep storage somewhere, but it's likely inaccessible and not something they'll be able to find quickly to satisfy my curiosity.)

There's election signs all over the place here saying "VOTE YES FOR FIRE". I mean, I guess after this many years of plague a change might be a good idea. Kinda wish locusts or a rain of blood were on the ballot though.

Random thought: Do companies getting pentests ever explicitly avoid large publicly traded firms in order to avoid the findings / sensitive IP used during the test becoming subject to SOX data retention requirements?

Related: the more I learn about the hoops publicly traded companies have to go through, the less I'd ever want to work for, own, etc. one. I can't understand why anyone would deliberately invite all of that pain and liability just for a potential cash-out.

(The same goes for VC - the minute you accept VC funding for a company it's not really yours anymore. But at least you're not risking jail time or company-ending data breaches dealing with them, compared to dealing with the SEC)

EEs of Twitter: What's the most work you've put into an apparently trivial board? I think the AKL-PT5 is my record. 5 years of R&D, ten PCB spins on the probe (plus more on failed prior designs). For an 11.15 x 5.6mm PCB w/ one connector and two passives.

Thinking of adding a UV peelable maskant to the mounting feet on my probes. Exposed components on the underside will be conformal coated, but I can't coat the foot or it will be impossible for the user to desolder to repair/customize it.

Replying to @azonenberg @bikerglen
Here's an example of @dymax E-MAX 906-B on an AKL-PT5. First application (a bit more than I actually needed), after peeling, and second application because I actually want to keep this on there for a bit.

A peelable mask will stay firmly in place during normal usage, protect the probe from shorting to anything on the DUT, but can be easily removed by the end user if needed. They can then use kapton tape or more peelable mask to re-coat after soldering the new foot.
