Hi, it's repair time. No, it's not a death star or a Droid. it's a a Sega toys uh, planetarium. It's actually a really awesome planetarium.

I think it's like one of, if not one of the best on the uh market. And what it does of course is it projects just like it is. Now I'll show you a bit more in a minute, actually projects the stars onto your um. ceiling.

It's really very cool and it's got, um, these removable discs and I'll try and put one up to the camera. I'll try and put a light behind there, but anyway, you can get all these different discs with it and it gives you a very, uh, realistic view of the night sky. In fact, this one's uh, particularly notable in that apparently like they are like proper star fields and things like that so they're actually accurate. um, star fields and they project them onto your roof and you know you sleep at night and you get this star field.

And the thing about this is that um, you can actually have it slowly rotate. um either north or south. It just changes direction for here in Australia and it's got a shooting star mode as well. if you turn that on, then every once in a while a little star shoots across your ceiling at night and it is really kind of cool.

Um, I really like this thing and it's got an adjustable uh lens on top which is really multi-turn fine adjustments. Got multiple glass lenses and stuff like that apparently which focuses uh, the image on your ceiling anyway. Um, it is busted. While it does actually project, you can probably see the light shooting out of there now.

but anyway. um, it doesn't rotate anymore and the shooting star mode doesn't work. It doesn't shoot across occasionally like it'll like. Come on, and they're just the shooting star trail is there.

But it doesn't like shoot across and well, it has been, uh, knocked off the edge of the bed. um, many, many times by the kids. Yeah, it's seen better days. So maybe one of those, uh, you know, hard knocks or something did a damage to the rotational thing in there.

If i, um, turn it on, I can actually hear the motor going inside. So here's the disc that's in it. We do have, uh, several others. I just put it on top of a light source and it's very cool.

This one actually has, uh, some constellations as well as um, the Milky Way is Starfield, so it's yeah, it just. I can't Words can't express how good this is. At night, everything's like super sharp. It's beautifully formed and the optics in it are just beautiful.

If you buy one of the, uh, like a cheap ass brand planetarium, I don't think they're anywhere close as good to this. um, Sega Toys one this is, I think one of the ducks guts ones on the market. Oh wow, I'm sticking that right on the lens of my camera. right on the front.

That's really funky. So anyway, here's the uh tray mechanism. and it just sits in here like this. so I assume that there's like rubber wheels in there.

In fact, I think I can kind of sort of. yeah, you can kind of sort of see down in there how that work. Little rollers on the side, um, that attached to this, so assume that they're not making contact. It could be.

I don't know. They're not. um, the spring is gone in them or something. Maybe don't know.

Well, those side uh, handles. they didn't uh do or allow me to access anything. So it just reminded me like, uh, looks like the thermal detonator from Star Wars? Does it Not like it's a little bit bigger, but I just got the look through the camcorder here looks like he's holding a thermal detonator. I've got to assume that it's all plastic, catch based.

maybe? Well, that's a step forward. Ah, there we go. There's a screw. so is that it? Oh yeah, yeah, that's it.

That's just one screw. There we go. We're in. like Flynn.

Check that out. It's a little bit dusty, but uh yeah, we can get access to the do. They spring back first. Yep, yep, they spring back so the springs seem intact.

Let me plug this sucker in and see what's what. All right. So we're projecting and if we hit that looks like we've got a reduction gear down in there, which is supposed to turn this. I mean, it's going to be incredibly slow.

It's fascinating. I might have to take the thing off. It's got four screws in there. I'm not seeing or feeling that rotate.

So yeah, maybe something. Yeah, the motor. I can hear it. This is the shooting star thing because there's a lead in the bottom of there.

It's just got two wires going over. I reckon there's lead in the bottom of that and that wheel under there. You can't see it. But ah, you can see a slit down in that.

So I think that is how the shooting star works. Yeah, this is obvious how it works once you. uh, put the disc in um, and put in your thinking cap for two seconds. Um, yeah.

What I thought might be another. um, a belt down there is not. That's the. That's how it turns the edge of the disc.

You can see the disc in there, just makes contact with the bottom part of that rubber. And that is. I can see it moving, so there's definitely engage in that. So that's not loosey-goosey So I think the fact I think that's down in the gear mechanism down there is our problem.

And as far as the lens assembly, well, there is actually an end stop on that and this is actually multi-turn It is actually going up. Geez, that is. and it will eventually come out. I think.

surely. Yep, there we go. So there's the lens assembly. Beautiful.

So apparently it's multi. uh, like it's a multi-glass lens in there. So pretty decent quality. and that's inside the death star.

Check it out there. You go all on one Pcb. That's just going to be a little micro down in there. Which one is it? Let's take the little Qc sticker off there.

Get your bets ready. I'm betting a microchip. I reckon it's a microchip jobby. Am I right? Can't damn see it? Hold onto your hat.

Look what I found inside just fell out. Um, yeah. I I suspect that's needed for something, so we'll find out shortly. But anyway, can't read the damn chip and well, yep, there's your problem.

Um, there's our motor. there's our drive. anyway. that's where that came from so I need a replacement for that.

Unfortunately, I don't have like a replacement built kit. Um, because I'm not into like, you know you would have these if you were servicing. uh, tape decks and stuff like that. None of that Cd rubbish.

Um, although you know, no, I don't think any Cds do. Any Cd players actually use a drive belt in them. Usually they're a direct drive. I, I don't know.

Anyway, leave it in the comments. uh 27 28 millimeters diameter, something like that and well you know you could try and glue that back together. But uh, it's like pretty how you're doing. Um, I don't like my chances and That is about 0.8 millimeters or so.

So like 28 millimeters by 0.8 millimeters. You're not going to typically get that in an o-ring set, which I was, uh, looking at recently. Actually, I can't remember like it was only like a month or two ago. I thought, oh nice to have like an o-ring kit or something.

like because I don't actually have one. Um, but you wouldn't typically get. I don't think that sort of, uh, thin diameter, like sub 1 millimeter diameter in like a 30 millimeter, uh, odd diameter. Uh, o-ring like that.

They typically come, um, thicker. so you would usually get these in little uh watch, um kits. These would be like o-rings in watch kits and I checked on ebay and you can't actually buy um watch kits in like 0.7 millimeter diameter. One I found, um, somebody does a little pack here with all different diameters.

Um, that might suit and I think well, I'm a bit of a watch aficionado. Um, I've actually got watches and I've actually got two of these Casio Fx91ws. In fact, I did a second channel video. Um, just doing this watch like rotating like this for like continuously for like 10 minutes or something.

I'll link it in up here and down below. Um, it was. Yeah, I was gonna do a video on the uh on how this has been, like, well, the whole history of the Fx 91w, how it's been manufactured for. I don't know what is it 30 years now or something.

It's just absolutely crazy. Um, and it's You know it's the watch of choice for terrorists of course. Um, it's the watch Osama Bin Laden? Uh, War One. Um, as did uh.

Clinton I think um, Warren Fx? um 91w. So make that of what you will. Um, but anyway, yes I was going to do like a video on that and then I've had this sitting here for ages. So anyway, um, I thought maybe just as a fix that looks like it might actually match because the o-rings gonna be.

I I think I believe it has an o-ring Um, it is water resistant. Um, so yeah, that might work. I'm gonna crack that open and there it is. Um, it looks like it's not round.

Is that going to pop out of there? Anyway, this is the world's best-selling watch. Casio Fx 91w An absolute classic. Can I get that out? Ah no no, it's like ah, what a bummer. doesn't use a regular nut.

I thought that might have been a round o-ring inside. I haven't looked inside one of these for decades. So yeah, nah, I didn't know that's not gonna work. It's got like fixed sections and thin sections and stuff.

No scrap that idea. Anyway, that was worth a shot. So I looked at a few old uh watches I had lying around. Unfortunately, they were all too big.

So there's the uh original and no, it's going to be loosey-goosey in there so they're no good at all. There's nothing you can do so. uh, the only thing I could do at this stage. Um, I've ordered and like a um o-ring uh kit.

um so hopefully I can fix it uh, properly later. These are a number 10 rubber band. and yes, rubber bands do actually have a like size chart index thing. Here it is, um and hopefully that will, uh, that is smaller than that but it should then just expand.

I mean, you can. Obviously you know it's a rubber band. You can expand them out. uh, quite large, but that should probably just have enough tension on it.

I think. um, the only other one I could get was a number eight. um and that came in a huge like half kilo bag of the things. So I think this one will do the trick.

So it looks like I've got to take this top plate off here. Um, interestingly, there's the motor in there. It's got a nice little uh, die cast alloy, um thing surrounding the motor. This got a nice big chunky um thing that holds the motor in place.

I like that. um that's I guess to stop any movement, uh, vibration or whatever to dampen it. Whatever that's doing. Um, it's a very nice touch.

I like it. Now the thing is, I don't really understand why they use, uh, the rubber bands at all. Why couldn't you have just like a cog come out there? A small cog on there driving this cog. Then they got another the o-ringy uh belt thing uh, built as the correct um term under there to drive that which then drives that like why? I I don't understand.

And then of course they've got another one on the bottom. which then, um, dries the shooting star. uh, wheel here. Um, so I I don't know why you'd bother.

Hopefully that lifts off like that. Aha, there you go. Win a win. A chicken dinner.

That's nice design so then we can get the belt on and then that. Just the cutout in here just goes over the belt. So this is a little bit bigger than, uh, the 0.8 millimeters we had before, but no workers. Let's see if it works.

All right There we go. Yeah, yep, that's just got enough tension on it. I think that's going to be a winner. Yep, number 10 rubber band back on that rubber band is very close to the plastic there.

So yeah, it's a bit how you're doing, but no wackers. We'll give it a go. so let's turn it on. Whoa.

Whoa. No, No something's getting stuck. Oh look at that. I don't think it's supposed to do that.

Like the motor is. kind of like it's like losing torque there. It's a rubber band. I mean, it could be touching.

Yeah, it doesn't take much to to stop it. unfortunately. Damn, that rubber band is not perfect. I'm afraid.

No. There we go. It's come good. Now There we go.

Yeah, that's the angle of the rubber band. I think on there because it's not round. It's like these are like square rubber bands. so it's actually on an angle.

It's actually, um, not flat. Of course because it goes into, uh, the curved, um. friction wheel. So it bends.

It wants to bend 45 degrees to put the corner in there, so there's a corner sticking out. But there you go. it's actually running. Um, fantastic.

I'll put it back together and see if we can project winner winner chicken dinner down in the dungeon. Catch you next time you.
