bad idea for an experiment:
take a betamax tape, and a vhs tape. open both casettes, remove the actual tape, and put the beta tape into the VHS cassette.
First of all, it won't play. obviously.
but then see if we can record to it and play it back.

dooo dooo doo dooo....
I'm in. (to the Beta tape)
and I'm into the VHS tape
@skaverat it's the mini-series, prior to going to a show
@foone okay, but the important question: what episode of galactica is it?
cross-winding the tape
where's a VHS rewinder when you need one?
why VHS beat Beta in one, oversimplified example:
The reel on the right is beta. the reel on the left is VHS. A bigger reel meets it holds more tape. More tape means it can record for more minutes.
Beta tape is now wound onto the the VHS reel.
Now I need to unwind the other reel of the VHS tape and splice it back together
@mkgraham me too. But sadly I don't trust my beta players to play beta tapes, let alone horrible mismatch VHS tapes
@foone I'd like to see it the other way around as well
@thomasfuchs I guess that means, given the history of home media, that the final version was Blu-ray
@foone tbf it was in beta
how do you unspool half a kilometer of tape?
a power drill, obviously!
@foone ...on my desk, waiting for me to convert it into a VHS tape cleaner!
okay, tape is back together. Now I'm going to manually rewind it, because I don't want to risk my VCR slamming into the end of the tape at high speed.
I should 3D print a VHS-reel-to-drill adapter
PRINT IT
still printing but I finished rewindng it by hand
and it's back together. time to go see what the VCR does.
I am currently recording a video onto the Beta-VHS tape. You can probably guess what video.
and it gave a signal! it's gibberish, of course, but I'm amazed. I thought the VCR would just stop or show nothing.
So this is what happens if you play a Beta tape on a VHS VCR: gibberish lines.
Here's a GIF of what it looks like in action
And here we go! So the answer is: YES.
You can absolutely record VHS signals onto Beta tape.
(The pause at the beginning is just me not starting the blu-ray player at the same time as I hit record on my VCR)
There's no audio, but I'm not sure if that's a problem with my setup or a technical issue with the tape. I'll have to play around with it
okay yep: I hadn't connected one of the cables to my PVM correctly.
The audio is fine on the VHS-recorded segment. There's no audio on the beta-recorded segment.
also I've ejected the tape three times now with no snags. It definitely isn't exploding my VCR that I can detect.
@ruthan oh no. That was just the obvious video to test with.
@foone did you seriously do all this work just to set up a rickroll
@foone Cursed
@mwichary cursed is how I roll
@foone Was someone insisting that video tapes were like Coleco Adam tapes and they had to be formatted at the factory before a consumer could use them?
@fozztexx not that I've seen. but I was wondering if it'd work. I expected it would, but expecting isn't the same as knowing.
@74k08 Not really. A few horizontal lines but that may just be a speed issue because my tape isn't properly wound tight
@foone Nice! Were you able to spot a difference in quality compared to VHS?
@foone Dammit “hellical” was right there and I missed it
@mwichary that's a good name, yeah!
@foone Foone finding increasingly cursed ways to rickroll people, where will this end?
@Yuki end? this is where I STARTED

My 3D printed drill-to-vhs adapter looks good.
I wound it the wrong way, it hit the end of the tape, and snapped.
I probably should have used a higher infill, but fundamentally this is a kinda bad idea.
@jbaggs that would have been a smart idea, but no, I didn't
@foone I'm sure you plan on using some sort of limit on the drive motor, but this also just feels like the sort of "very bad idea" I am entirely here for.
@ChuckMcManis yeah that's what I'm doing for my second print: I changed the diameter of the bit so I can put it in my variable torque screwdriver
@foone Also if you are using a variable torque driver (like most battery operated drills are these days) set the torque level to the minimum needed to wind from zero. That should be much less than the torque that would break the spindle you are using.
@foone I've found that applications like this get more strength from increasing "shells" than they do from increasing "infill". I'd try it again with 4 or 5 shells and see if it still breaks.
I redesigned it: Instead of having a bit, I just put a hole in it, and then jammed a double-ended hex bit into it.
Now I can use it on my variable-torch screwdriver, and it works just fine!
@RueNahcMohr the screwdriver will stall if it exceeds the torque limit, so it shouldn't be too risky for the tape
@foone no safety tho, it could break the tape
@ChuckMcManis yeah. I set it as low as I could and still have it turn the reels
@foone But you have to set the torch very low though right?
@gewt suggested I repeat the experiment with some u-matic tapes, but unfortunately they're a different width: 3/4 inch (1.9cm) instead of 1/2 inch (1.3cm) like VHS and Beta.
