content: Hi!I just finished off an analogue delay pedal I've been building! All of the electronics were done from scratch and I've learnt a lot. It's definitely not the most polished project ever but I'm pretty pleased with it. If anyone is interested, here is a videoThe sound isn't exactly pure, but I think it creates an interesting effect.

content: Really nice! That sounds amazing!Could be interesting to try this with an analog synth..- How much of the original cassette recorder is left in there? Can the tape be flipped when it runs out?Great work!--Christoffer

content: ThanksI did all of the electronics myself (I chose to do it the hard way so I can learn as much as possible), and all that is taken from the cassette player is the cassette mechanics, tape heads and motor (although slightly modified).

content: Oh, and the tape isn't particularly easy to access. At the moment, when the tape runs out, you will need to disassemble it a bit to rewind it. (You couldn't flip it because it's a modified tape) but maybe I'll get around to making an infinite loop tape at some point.

content: its not too hard to make it a continuous loop.*take a look at cassette tape drum machines.

content: I gave it a shot but I couldn't get it to not jump, but I think I will give it a better shot when I'm back from uni and have more resources at my disposal

content: If you are talking about a loop, try an angled splice, you may not be able to stop it completely but you can reduce it allot.eddit, or even find an auto-reversing transport

content: audio tape has allot of artifacts, I would imagine that slowing the tape further could even be considered an "effect."

content: I wonder if this could be done with a floppy drive... no need to flip it as the tape doesn't run out.

content: I remember waaaaaaaay back when in the late 80's I use to have a toy that was a pull string but you can record sounds onto it.essentially i was a a small 3" floppy disc with a tape head on a guide.. Wish I could remember what it was so I could show n tell'..yes the aforementioned toy did also use batteries.
