Who’d’a thunk it?
A discussion of random numbers at Squidwrench brought those gamma ray detectors to the top of the heap, with the observation I probably needed a few more Darlington transistors:
Sorting two lots of 50 transistors by gain kept me out of trouble for a while:
Those are MPSA14 NPN and MPSA64 PNP transistors, with DC gains ranging from around the spec’s minimum 10 k spec all the way up to well over 100 k.
Page views for 2018:
At this late date, the RepRap site has a much better G-Code reference, at least for the weird and wonderful assortment of 3D printer commands.
Given that I’m at best a secondary reference for Toyota Sienna ABS trouble codes, things must be getting grim out there in the minivan crowd.
And, as always, houses (and especially plumbing) are trouble!
As for everything else, well, it’s just me and my shop notes …
WordPress reports 101 k ad impressions per month for 24.6 k “page views”, suggesting most folks see four ads per page. If you’re not using an ad blocker, start now!
Those seem to be the most aggressive (and thus highly desirable to advertisers) video ads, because WordPress pays me a whopping 8¢ per kilo-impression; a few percent of the Youtube rate. The numbers are dropping, though, suggesting ads will never push me into the ranks of the thousandaires.
Now you know.
You can find anything on eBay (clicky for more dots):
The key information:
For that price, I’d expect in-person hand delivery.
Stipulated: ZVNL110A MOSFETs aren’t in production and we’re buying from diminishing inventory, but (as of late December 2018) they’re still available for under a buck apiece in small quantities.
It could be a pricing algorithm corner case, a money laundering scheme, or just a typo that could happen to anyone. As the news sites put it, the seller did not respond in time for this posting …
Perhaps they should just saw off the bollard in the middle of the entrance and be done with it:
Some backstory may be of interest.
I spotted a defunct paper wasp (or, more likely, a hornet) nest on a lawn under a tree:
Call it basketball sized, large enough to raise plenty of wasps:
I vastly prefer encountering those critters after their season is over …
We spotted a pile of room safes in one of the motel stairwells:
Judging from what we found in the room, it’s out with the old and in with the new:
Too bad about the mounting pedestal, though: same size, different orientation.
Something unexpected always lurks in the datasheet …
One day, long ago, this tree grew in a certain bedroom:
And then a flower appeared in the laundry room:
Much to our delight, she asked for forgiveness, not permission … which was, of course, granted immediately.
