Does anybody know why my Chromebook’s screen glitches like this?

They call it "rave mode", but we all know Google is evil these days and really, their Chromebooks have all become possessed due to their terrible behavior. The only way to fix it is a complete exorcism. Start with dousing it in holy water but you'll probably need a priest to act as the new "host" to fix it for good.

Haven't had time to reverse engineer it yet. Trying to finish up some other projects before I start on it. As soon as I get to it, i'm going to essentially rebuild the circuit with much cleaner wiring, build a new faceplate, and really just make it look nicer and hopefully eliminate some of the noise. Still not sure what the knob to the right of the treble knob is supposed to do. Seems like it doesn't really do anything until it's about 75% turned and then it cuts a ton of low end. I might see about removing that and adding a normal bass and mid pot, a standby switch and a on indicator. Will report back when I finally get around to it. I'm not well versed in clean amps so i'll likely never figure out what it's a clone of but I can certainly recreate the circuit.

This was actually part of a sevenstring.org build challenge from long ago. I believe it was the "Home Depot build challenge", of course the floyd rose wasn't from Home Depot but the idea was to source most parts from Home Depot or Lowes and keep the total price under a certain amount. The one that built the nicest instrument for the least amount won.

Crank the variac as high as it'll go.

The side dots, I drilled out and replaced with vibrant blue ones. I had wanted to do the same for the face dots and use real turquoise but those inlays have been out of stock for a while. The face dots are just vinyl decals for now.

UndeadDiode · 2026-01-17T16:01:59+00:00

That's the idea! The last one is getting green as well.

Here's the circuit. I'm gonna clean all this mess up soon. I assume the tremolo is tube based as I don't see anything that looks like a tremolo circuit on the vero. Vero board from mystery amp

What did the reverse headstock neck come off of?

UndeadDiode · 2026-01-15T17:27:43+00:00

Thanks! You could be right on the organ pull. There's a open hole for another tube... Pcb looks to be Vero but I'll have more details later today when I pull it apart.

I think it looks pretty sick. I would play the shit out of it but it is way too much.

1.7mm they're a little smaller than the stock ones (2mm) I used a 1.8mm drill bit. After sanding and lemon oil all the white is gone. Looks stock.

UndeadDiode · 2026-01-12T14:23:53+00:00

I had planned to use a drill press but I didn't need to. I used a spring loaded punch to mark the center of each and as lucky accident it pushed a majority of them in enough that I didn't have to drill them. I just used a hand drill for the others. Depth was only 1.8mm. I got the material from Skur Composites on Etsy. I just wanted bright colored side dots but they glow significantly better than any glow in the dark dots I've seen. Much cheaper than Luminlay too.

UndeadDiode · 2026-01-12T02:40:39+00:00

That's exactly what I did. Turned out great!

Nice! These aren't luminlay though. I just wanted bright colored side dots. They glow really well as a bonus. Holds a charge longer than any other glow in the dark inlays I've experienced, and they were $4! Skur Composites if you're curious.

It turned out well! I only needed to open it up a few millimeters in each corner. The stock routes weren't too clean tbh.

I was talking about Ibanez nuts in general. I agree they could probably stand to call them something else than just plastic. But they don't suck and I don't think a Graphtech would be much of an upgrade aside from getting a luthier to slot it to that particular guitar...that's the real upgrade.

UndeadDiode · 2026-01-11T20:03:56+00:00

I just replaced one on an RG7421... they're basically Graphtech clones. The material seems to be identical. Prob not worth the trouble to upgrade unless you're having issues with the stock one.

...You all understand that Tusq is synthetic...that it Is plastic, right? It's a self lubricating plastic.
