Well, That’s Not as Annoying

After a bit of research, I realized I was most certainly using the wrong revision of instructions. Whoops.

I have a Rev 4 kit, but the instructions I’ve been using are Rev 3.

Well, that also explains why I have

  • four 10uF capacitors instead of six
  • a few extra 1uF ceramic capacitors and
  • why I have two extra resistors laying about

The good news is that I won’t have to remove or rework anything, yet I won’t know for sure until I’m done assembling and testing.

Note to self: make sure the schematics match the PCB… and vice versa.

The story so far:


Still several more things to do yet:

  • toroids to wind,
  • a few potentiometers to install,
  • jacks for headphones and an external key,
  • a few pushbuttons,
  • and of course a display

Will it work? No idea. But I’m eager to find out.

Alerts = Interruption + 1

I had yet another audible alert trying to get my attention.

Because I use several virtual desktops, and don’t have everything avilable on screen all the time, and because developers don’t have a consistent/meaningful method (the Apple Notifications concept is really useful, but isn’t well-adopted), that alert could have come from anywhere.

I can’t see everything all the time, so there was no way to see whether the alert came from any particular app.

I spent like 10 minutes trying to figure it out. I clicked through every open app to see if they each had their own, recently-added component or feature, or additional alerting/notification panels.

No idea what it was.

Then, another alert chimed away. Exactly the same sound. Definitely an alert. But from where?

Then it dawned on me: I’d heard that same alert maybe a month or two ago.

It was just my AirPods giving me the polite notification that a pod’s battery had 10% remaining.

So, I’m not complaining about Apple. Not at all. I’m not even complaining about getting this kind of alert: it was saying, effectively, “headphone batteries are getting low”. In fact, an improvement might also be an additional ability for the AirPods to invoke the connected device’s Notifications panel.

What I’m really more annoyed about is the proliferation of notifications in general. However trivial they might be perceived, are still interruptions to your workflow.

The regular frequency of SMS/text messages? Interruptions. Paging alerts? Interruptions. Getting FaceBook/Youtube/Twitter/etc alerts? Interruptions.¬†Alerts about truly trivial tasks? Interruptions. An inconsequential outage of something that’s unused? Interruptions.

Oh, and if you insist on having so much involvment in all of that assorted tech that you want to get endless interruptions, fine.

But if you insist on also having audible-alerts that can be heard by anyone else within earshot: not fine.


Yes, buy a holster. At worst, it’ll put you out a few bucks — I have holsters from $10 (Uncle Mike’s) to $140 (Galco shoulder rig) and many in between. My pistols never go anywhere without being stowed or secured in them.

A holster will keep your pistol safe and prevent you from killing yourself.


Normally, when the primer is struck by the firing pin, the primer detonates and ignites the powder in the case, propelling the projectile down the barrel.

There are times, though, when the primer is struck, but it doesn’t detonate. Instead, is smolders ever so slightly until a short time later — up to a minute! — the powder ignites.

It’s called a hangfire.

The right way to handle it, of course, is to always keep the firearm pointed in a safe direction. Never point the muzzle at anything you don’t want to destroy.

Linked here is a good example of the timing of a hangfire… and an even better example of how NEVER to handle one.

Honestly, I don’t know what line of reasoning could ever possess somebody to look down the barrel of a firearm after they suspect something is wrong with it. Maybe that’s how they saw it in those old Bugs Bunny cartoons.
