We had a "Glown Away Soiree" last night at Glass School. Organized by a bunch of us teachers assistants. Lots of neon on frames around the fire pit- a bar, snacks and music.
I forgot to get photos of the neon frames and the nice glow they casted everywhere, but I DID get photos of my overserve prevention light- a pair of articulating- to scale diamond shears that I made two or so years ago here.

We are Soiree ing responsibly by setting the high voltage diamond shears in a puddle of water :). That bartender better see those tequila shot pours.

I keep making these party lights here thinking they will break on their first use- but most of them actually end up sticking around campus forever. Someone even dropped these on the concrete ground last night and they STILL didn't break!

A little clip of our opening night "finale" after the MIT glass band played their horns. I bent "charms" for each of the class's instructors and got them done in half a day- in time for the opening night demo. 5 classes and neon red light with a high voltage animator- so naturally we went with a pentagram. A glassy high voltage pentagram of knowledge!

Also, the wifi is now "better" on campus thanks to some fiber ran into the woods. A few months ago I set up a Nextcloud server running at home that my photos back up to from my phone. I just realized that I can upload videos from Pilchuck to Mastodon straight from my home server! No need to clog the limited Pilchuck bandwidth

Another day, another #CRT #television fixed! This is the Sylvania 6420FF that I saved from the dump last weekend. Did some diagnostic work and figured it must be the flyback transformer, and I was correct! The replacement came in today and I spent about 45 minutes swapping it in.

I'm pleasantly surprised by how decent the picture quality is, these aren't super high end screens but I snagged it because it was the only smaller screen with something besides composite (S-Video in this case). I was able to get it up into the loft to test with the #snes and was also pleased to see the screen geometry is spot on.

I was a bit nervous because the replacement transformer wasn't the same model, but it works fine. As usual, I failed to document things as thoroughly as I should have, but enjoy the few pictures I did take!

Also, I will likely end up selling this set. If anyone in the Boulder/Denver area is interested, let me know!

Closeup of a circuit board inside a CRT television. The flyback transformer has been removed from this board, and the mounting holes are clearly visible along with the diagram on the board showing the transformer. Numerous other connectors and components are visible, if slightly out of focus. There's also a mixture of soot and dust on the board around the area the transformer was mounted.
ALT
The side of a CRT picture tube, with the anode cap removed. This is the single most dangerous area of a CRT, as voltages can build up here in the 20-30kV range (assuming the TV is fully functional, this one wasn't). The area under the anode cap is just a small divot formed into the glass, with a layer of clean glass exposed.
ALT
The old flyback transformer, with the anode cap still connected. This transformer looks okay, but it has a short somewhere (probably an internal short) which prevented it from working properly.

132,000 volt breaker connections - removed live in an indoor substation. Fun starts around 3:30.

I believe the arcing is from stray capacitance combined with the high voltages - a very small amount of current flow.

This live work is performed by trained experts with specific equipment.
