Bleeuuuggggghhh

I’ve been working a couple of insane days for the end of this week so the company has me staying in a nearby hotel they have trade with. As not to piss anyone off I won’t name it, but it’s in a beautiful place outside the city, on the bank of the river. They make a big deal about being a LEED certified facility.

Last night I got there, checked in, and went to my room. I picked up one of the coffee mugs and it had a waxy feeling mess on the outside and smelled like hibiscus blossoms. There were bits of the same inside the mug.

I figured it hadn’t been washed properly so I looked underneath. The “made in China” paper sticker was still fully intact. I sanitized it by boiling water in it in the microwave, let it cool, and used paper towels and isopropyl alcohol I had in my car to clean it out.

The next evening, the mug I had used was back under a paper dust cover and this time both of them had a thick coating of the waxy junk.

On the bathroom counter are two pump top bottles… One’s a hand soap that smells like lavender. One’s a lotion.. ….

Which smells like hibiscus.

You didn’t– really? Seriously???

Sonicwall, schmonicwall

How to forward ports on a SonicWall:

Okay, it’s easy, just start steeping some hemlock into the blood of a virgin in a quartz flask upon an altar of old single sided floppies and get to work—-

you will not know this horror unless you experience it for yourself and i recommend you not.

sonicwall was clearly developed by someone who had a raging databases-where-databases-are-not-due fetish.

you do not just specify addresses. you do not just specify ports.

No.

You create address objects.
You create service objects to define ports.

Then you define NAT rules.

HOWEVER…. if you manually enter or edit anything about a NAT rule, for arcane and horrible reasons that have apparently never been addressed in over a decade worth of firmware versions, they break. The only reliable way to create these rules is to go into Quick Configuration and use the Public Server Wizard. There, you can create your objects (or select them if they’re existing already) and bake them into a NAT rule.

Then maybe 40% of the time it works and the rest of the time you’re frantically SSH’ing into a remote shell somewhere else and crying into your coffee over the output of nmap.

FUCK SONICWALL.

Blue tape (everything old is new again!)

I was getting so annoyed with my printer repeatedly losing its build plate surface… This Malyan M200 / Monoprice Select Mini V2 originally came with a black sticker on the build plate which I replaced with a piece of PEI sheet held down with 3M 468MP adhesive.

Two spectacular failures later, I decided to try covering the aluminum plate with painter’s tape. This was a common technique dating back to very early experiments with 3D printing, and I figured it’d probably just fallen out of favor because PEI sheets or BuildTak or whatever were just better.

Several completely successful prints later….

I’m convinced this is the way to go.

The only odd part I guess is that the tape doesn’t appear to last for more than one print, but that’s fine. The print sticks to it well but pops off when it’s done. Now I just need to adjust my slicer settings a little (see the gaps where the infill didn’t hit the perimeter?)

Guess I’ll be keeping blue tape around from now on!

My brother, who runs a fabrication lab at FIU, reports that it’s specifically 3M blue painter’s tape – other brands don’t have a top surface that adheres to the melted plastic and the printer will just pull a “drag spaghetti around in circles” dance.

Cassie approves because now, instead of me wasting time scraping little bits of plastic off the PEI sheet, I just pop the print off, replace the bed with three new strips of tape, then go back to petting her.

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.
