ZDL CTD-105 cassette tape-delay 'project' - working
Posted: Tue Mar 15, 2005 2:23 am
Hi guys, <BR>so I actually have got my hands on this idea...if you remember while ago, I had that idea to try to build tape-delay based on cheap parts of used cassette deck(s). <BR>Well, the idea is(was) maybe a sort of primitive, but practicly isn't so simple. But at least I have found some free time to start working on it. I wish I had more time to play with toys..hah hah <BR>OK, so ... so far I'm on , let's say, experimental stage... And, man, this was actually a tough thing from 'craftmenship' point, but I've managed to make the damn thing running. <BR>Here's a small thumb: <BR><IMG SRC="http://www.interruptor.ch/cgi-bin/discu ... 99/913.jpg" ALT="zdl CTD-105 test"> <BR>Here are links to larger images: <BR><A HREF="http://www.mzentertainment.com/pics/pro ... test_1.jpg" TARGET="_blank">ZDL CTD-105 tape drive test</A> <BR><A HREF="http://www.mzentertainment.com/pics/pro ... test_2.jpg" TARGET="_blank">ZDL CTD-105 two cassettes tape</A> <BR> <BR>As you can see the idea is about running the tape from tape-drive 1 (cassette 1) to tape drive 2 (cassette 2), where the drive 1 is recording and drive 2 is reading (playback). This is the base. <BR>Again, it took me some sweat to make the thing actually running through. So the cassette 2 (where the reading head is) is actually the driving 'tray', the cassette 1 (writing head) is mechanicly passive (I took the pinch roller out), the tape is going through it - from left reel of cassette 1 to cassette 2 then through writing head, then to cassette 1 through reading head to right reel. I can fast forward and rewind the tape as well. <BR>I was thinking making loop instead, but the tape is so freaking thin and soft, it's not like reel-to-reel...very hard to deal with. <BR>I also placed another play-head in the position of erase head in the cassette 2 mechanism, but I am thinking now that it's not may be a good idea, 'cos it is really hard to place it well in that location. I may try later to place another head maybe in between the cassettes , but this all will depends on how I will be designing the whole thing later. For now it mast pass all basic tastes first... <BR>Alright , guys, you've got the picture , I guess. <BR>What this may be good for??? hah hah ha... so far, I have no answer, untill I get to actually puting together electronics. But the good news is that I can widely control the tape speed by changing viltage for the motor... The motors are 12VDC, so I could run it from about 4V through 12V ...and speed goes from full stop through something like double speed of normal cassette deck playback speed. <BR>ok, I'll drop update, when I next time get back to this ... I'm not sure when...when ever I get free time to play with it. <BR>Any crazy idea or comments welcome <IMG SRC="http://www.interruptor.ch/cgi-bin/discu ... /happy.gif" ALT=":)"> <BR>/respects, <BR>/Mike Zee aka Dr. ZEE <BR><A HREF="http://www.mzentertainment.com/dub_lab2.html" TARGET="_blank">ZEE DUB LAB</A>
