Yeah about that

Pay no attention the fact that this STL transmitter antenna installation looks like something generated by Shiv Integer ….

Not seen here– there’s a second pole with one more on it…. And no means of preventing the pole from turning….

Then at the other end, months ago, the vertical and horizontal got mixed up… Surprise, after fixing that, some meters now move farther to the right…

You poor STL, show us on this Smith chart where the confused engineers hurt you….

thanks i hate it

hi there, i need a combiner care package from Microwave Filter Company, thanks

Sadly, we DO actually need antennas pointed three different directions, but that’d let me eliminate one of the dishes (not seen in the picture here) that’s mounted all janky and was able to be spun around by the wind.

YEET!!!

Well, so much for that PEI print bed!

I was getting progressively weirder leveling on the last couple of prints I ran on my Monoprice Select Mini V2…

The original BuildTak clone sticker on the build plate failed, and actually managed to kill a nozzle when it did by snagging on it, so it was subsequently YEETed into the nearest trash receptacle and replaced with a PEI sheet. Now, that PEI sheet I got came with a big sheet of 3M 468MP adhesive transfer film which I used to apply it to the bed after cleaning it up and scraping off some stubborn bits of the stock sticker… You can see the PEI sheet here after it’d been sanded a few times to improve adhesion with some regrettable no name eBay PLA filament.

The blower and fan duct are the result of the stock fan proving inadequate.

It worked great until I found a print I ran today twisted up like a funhouse mirror, the adhesive under the build plate all bubbled and torn, and the PEI raised up and warped on one side as if it tried to rise like dough.

And suddenly it dawned on me, like every time I see someone’s photos of their printer on the Facebook group, they have binder clips on the edge of the glass or PEI bed. Oh gee, I wonder why, could it be that this method of fastening it Just Works without any complications whatsoever (as long as you don’t place them where they obstruct moving parts and, thus, find themselves YOTE into space?)

Yeah. Worked perfectly, though I think I might do it with four clips next time to avoid the PEI sheet lifting and warping the print (not sure if it’s actually doing this — the first layer showed no signs of leveling issues, so it may just be perfectly fine).

Speaking of Monoprice printers…. My Mini Delta decided to inexplicably spring back to life when given a very old SD card with the Marlin firmware build! I was about to rewire the whole thing to a RAMPS board, but now the stock controller came back. Flippin’ weird.

I now have an Anycubic Kossel Linear Plus that’s waiting for me to figure out how the heck to set the delta parameters on as well.

What craziness is all this??!!

Addendum: it takes a lot of clips. A LOT.

Oh that’ll wake you up

The RMT for this month came through just GRRRRRRRRRRR-EAT!!!

Warning: Replaying these files on any broadcast station or cable TV system is a violation of FCC rules. Yes, there are people who would be ignorant enough to try it otherwise (oh hi Bobby Bones show).

This is the end result with Billy and Patrick being very very confused…

The actual audio received by the SAGE Endec:

Had this been an actual emergency, uhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh.

FNORD!

AaaaaaaaaaaaAAAAAAAAAAAA

there are no words. Someday I will try to come up with words in the process of writing a notice of retirement, but that day is not today.

The really fucked up one is an Armstrong tube transmitter from the mid 1990s.

The tape wadded splices are in the ~8000 volt plate supply. Also in this collection, a Nautel that ate a BNC lead that then ate several expensive RF transistors.

or not because this is just perfectly me

Nautel nightlights.

Weird old Italian STL receiver I put in service after a nice new Armstrong XLink went deaf

Additional folderol. The crazy manifold is a concoction by Steve Wilde. The voltage reading on the service panel at exactly half voltage is from the days that PG&E lied to us and said the power was fine while wires sizzled away downed in the snow
