 Well, great search brought you by digikey and a free user power of engineering help you find the things on digikey.com sometimes seem to look for things that she's looking for. Yeah, I'm usually I mean, I look I use it a lot. So this is what I this is what I did actually today. This is what I was looking for. Alright, so just talking about how I'm going to make a interface into an Apple disk to drive and the Apple disk to drive was a low cost version of the sugar five and a quarter disk interface and to make it low cost was not Amanda was who's friend of the fruit but Steve was the echo. We started Apple. What he did is he removed a lot of the drive interface that would add cost and one of the things that he removed with the index sensor and the index sensor tells you when you've rotated around one point. So as I was just showing off because this video is cut, you cover quickly, you can fake an index sensor by having some black plastic on the spindle, the motor that goes around and using a optical sensor as shown here you bolt it on and then you look for that gap you have to have something that it looks for. And as long as it only happens once per evolution, it counts as an index sensor. And then you can tell when your data begins and you have a marker for the beginning or end of the set of the flux data coming from the floppy drive. Because otherwise the thing is that the rotation isn't consistent, it can vary and so there's no way for you to know where to stitch the data unless you know exactly where the index is. And so like having that like, I did one rotation is really, really valuable. Otherwise, you're like, did I, it's like, you don't know, did I do one rotation or one and a half? Very hard to tell. And also you want to have, you might want to also read the data consistently, you know, indexed to the index pulse track to track, which is a security system that was used in Apple to floppies to prevent piracy. So one thing I was looking at today is, you know, I wanted to have a breakout board that would make this easier to mount than the setup because there's like a little bit of like this kind of free wire soldering and then like, oh, there's like a wire here and a wire there and like three wires and then, you know, maybe you have a switch as well. And so I wanted to make it easier. I wanted to have an easier to mount version of this sensor, which I love the sensor and everything, but it's it's not easy to use. So what I want is an optical sensor, I'm going to use optical because I find that it's a lot easier than magnetic sensors. It's like, it's kind of risky, you have to put a magnet and then let's say it's off and then it erases your floppy drive, your floppy disks. And so I want to be able to integrate all this onto one disk drive as onto one breakout board for the disk drive. And so what I want is a light sensor like this one with a transmitter, there's an emitter and then a receiver. And then it bounces light off and then it gives me an analog or digital signal back and ideally, it would be surface mount and ideally it would be right angle because I want to have the PCB and then I want to have the sensor coming out like this for easy mounting, right? I would, I would bolt the sensor PCB. Let me find like this. And then the sensor would be pointing out like, you know, in the plane of the PCB. Sure, that this is actually a little bit more difficult than I thought, but let's go to the vintage key and see what we can find. So I want optical sensor, optical sensor, lot of options. So there's photore interruptor slot type. That's not what I want. A slot type is well, I'll show you it's it's the same idea, but it has the emitter and detector on opposite sides of a slot, which is great if you have a disk that's going through but I don't have a disk I'm trying to reflect off of the drum. So while this has the right idea, it's not quite right. There's also a couple, there's two kinds of images, the reflective, there's photodetectors, but I think that these, yeah, this doesn't have the emitter part. So this is just the detector. And so I don't want that I want something that's integrated that has both because this assumes that you have some other emitter elsewhere and I want to have like an all in one thing. So that's a different thing. So what I want is again, not the slot type, but reflective and analog output because that's basically the sensor I was using before, except that version was like panel mount or was like solder type. So I want to look for active. So let's look for active. And you know, a lot of the other settings I don't really care about like the current or the DC four or the voltage because again, this is all going to be at low voltages anyways. So everything is within reason and I can always add an op amp if I need better signaling, leveling, whatever, potentiometer. What I really want is surface mount, if possible. So let's look at surface mount, not a lot of options, which could be good or could be bad. And then let's look. So this is, you know, this is very cute. You can see the emitter and detector, but this is pointing up. You can see it's meant to be soldered and it points up, ditto points up, ditto points up, ditto points up, points up, up, up, up. I mean, this one's like super cute, right? It's got the two little LEDs, but again, pointing up, pointing up, pointing up. So, you know, I looked through all of these because there wasn't a filter for right angle and that turned out I actually couldn't I mean, this one is not actually surface mount. I mean, it's axial surface mount. But of other versions that were available, I did not see any that were right angle. It was kind of a bummer. So, you know, sometimes you don't find exactly what you want. So let's get rid of the mounting type. I turned that not to work out. And let's do, if you can do surface mount, at least do through a hole. Because I don't want to chassis your panel mount because that's what I had before. And that's like, even more impossible to connect to the PCB, at least with through hole. It's like I can, you can solder it somehow. And let's just get rid of marketplace for now. Just so only looking at stuff that stopped. And then actually, like what's funny is like, okay, like this one, I actually seen this one, this one's cute, you know, through hole clips in but again, vertical style. And then this is also vertical style. You see the two LEDs pointing up, pointing up the two black bars or the emitter and reflector. This is the one that I'm trying to replace. Ditto, ditto, ditto. But you know, what's funny is like I looked around. And actually, the best option was the first one, I kind of like flip through these because again, there was no real filter for right angle style. It was like, you know, you're expected to mount these however you want. But turns out this one, the TCRT, sorry, still getting over this cold, was like the best option. So if you look at the data sheet, it's available in two kinds, but this one will actually do the job quite nicely. It's it's through all but like, you know, we'll solder it and have the legs come out and clip them. And it's very simple, just has the LED on so we'll have a, you know, resistor and then the photo transistor that we can have as the signal input. And it's pretty easy to use. And it's perfect for bouncing stuff off. And looks like, let's see the distance it works at this is the ratio collector emitter distance, you know, it works best at one millimeter, like very close, but it'll work up to like three or four millimeters looks like, even up to six millimeters, there's actually quite nice. Like it's exactly, you know, that means I have a little bit of space for the mounting me show the the mounting now this is one second. You can see the math is actually pretty close. It's a couple, a couple millimeters. So we should be like, totally good on the distance. And the otherwise usage looks good. So I like this looks like they have a they have a version that's like bent, if you want to have it like pointing that out, you know, after all, but just make sure that you I'll get I'll make sure I get the version that's vertical style. The good news is that there's lots in stock. Sorry, this is the footprint of the Vichy TCRT 1000 40,000 in stock and they're like super cheap 50 cents a piece. This is the sensor I'm going to use and I'm going to now design a PCB that will be able to mount on a standard five and a quarter drive or an apple drive and give me that reflective pulse for the index sensor. That's the great search.
