Monday morning trail run had an unexpected "private land" sign half mile down one of the trails. Never fear, I've been practicing bushwhacking for years!

First there’s a bear track, and then there’s this guy!

Throwing out all the old stuff. 709 and 741 opamps bought before they knew about static electricity. But in ceramic and metal cases! You just don't see that kind of thing any more. Not for a really, really long time.

#electronics #opamp

709 family op-amps. Chips are marked 709, 2709, and 2809. The 2809 is stuck in ordinary white foam in an ordinary plastic bag. Not just no static protection, this is the worst thing you could possibly do.

@ericphelps Static, I remember it well. We'd spray fabric softener on the radio station carpet back in the 70’s, because touching automation equipment with any kind of static buildup would cause it to reboot, jump, freeze, or some other calamity.
That and "massaging the chips" because they were all in sockets (re: static) and their legs/contact got corroded due to the giant furnace of a power supply under the CPU boards.

Dropped my nephew at the airport last night, good visit. Up and over Pacifico mountain today to Fountainhead spring and back.

Saw over 30 thru hikers, the peak of the bubble is passing now.

Today’s quick 3d print of a “pill placer" for our old dog. Big enough for the capsules he has to take 3x a day and hopefully more accurate and less intrusive than my fingers, with less chance of a munched finger.

And it works!

It worked so well that we aren’t sure if it really happened nor is the dog, "it’s over already??”

Wife wanted the ability to take unit apart for cleaning, which first design wasn't well suited for. This one is just two parts, super easy to print and assemble. I need to make the ring a bit bigger and then I'll post it to Printables.

A thorough examination of of how to visualize part cooling flow and then testing a new attachment for Bambu Lab X1.

Found this model, but haven't tried it yet. It also breaks up the airflow differently than stock one.

I found a 3d printable version, but after a quick reality check it became obvious they made it for a totally different sized pill. Also needs to be at least 2x that long for our dog if we are going to stand any chance. I’m whipping something up in Fusion 360. Lots of chamfers on the edges and sturdy enough to survive the molars of doom.
The pill is a soft capsule that falls apart after the 3rd failed try of getting it to the back of his throat just using fingers, which barely reach.

All of which totally reminds me of this:

@teotwaki I figured it would also act like a tongue depressor, since his tongue seals the back of his throat the moment we open his mouth a little ways. I can't imagine being able to shoot anything in, although that would be fantastic. “;^)
You're right on the length, just did a quick test with something about 100mm and there's ample room coming from the back side.

Question for any woodworkers: how resilient are electric planars to screws and does it even make sense to plane old deck boards to reuse? I was thinking of flipping them over.

@smellsofbikes I’d like to think that I would find, remove them all, but have to be realistic. Remember years ago trying to tighten any heads sticking up and some just broke off.

Wife and I went for a ride on rail trail and then by Goose Pond. I’d recently discovered it was almost empty, some kind of improvement project to the dam.
There's water closer to the dam, but as you get further upstream it gets shallow and the remains of tree stumps appear. I wonder if that area was submerged after they built the small dam in 1899? Having driven and biked by there over the years it’s quite striking to see it devoid of water in so many places.
