    Changing the speed of a walkman motor with motion

    Hi KrisBLueNZ, A huge thank you. What you have done is here is fantastic. I'm massively grateful. Sorry i couldn't post sooner, i was called away to work on a project over the weekend. I need to read over all of this properly, but i think i should be able to build it. I haven't done anything...

    Changing the speed of a walkman motor with motion

    Thanks a lot for this KrisBlueNZ. Really appreciate your input. You are right, what you've described is exactly what i'm hoping to achieve. Whilst getting any kind of change would be nice, what i would really like is for it to play at normal speed when illuminated, and when the light is...

    Changing the speed of a walkman motor with motion

    Thanks a lot for your help there KrisBlueNZ. I've picked up one LDR, and i will get another lower resistance one tomorrow too, so i will begin to do a little experimenting then, and we can see what happens...i do have an idea about the light and how to control it, but need to see if i can...

    Changing the speed of a walkman motor with motion

    Great stuff Steve, thanks a lot for this. I'm going to head out into town now to get a selection of CdS cells, but i notice there are many different types. Is there a specific type that you would recommend i get? Or should i try a selection? The place i'm going to is here...

    Changing the speed of a walkman motor with motion

    KrisBlueNZ - thanks so much for these, really kind of you to do that. From looking at these, does it seem possible that the circuit will work, and the speed of the motor can be controlled with an equivalent light dependent resistor?

    Changing the speed of a walkman motor with motion

    Hi Steve, My camera wasn't so effective at very close range, so i scanned the boards instead. I got quite clear results on one of them (the FX443), but not so much on the FX423. I can try re-shooting if it's still not possible to view the necessary details, however i have also included the...

    Changing the speed of a walkman motor with motion

    Thanks a lot (*steve*), really appreciate that. I will get on the case straight away. I have a reasonably good camera so should be possible to get some accurate shots i hope.

    Changing the speed of a walkman motor with motion

    Hi again, Today i had some success with the Walkmen. I was able to dissasemble 2 that i have and locate the potentiometers in each case that control the speed. I have decided that in the first instance i would like to try swapping these potentiometers out for light dependent resistors. It's...

    Changing the speed of a walkman motor with motion

    Thanks a lot for your response Steve. From what you mention, it does sound quite complex for my skillset! Fundamentally, all i want to do is have the sound change based on some kind of proximity interaction...it would be great if this was gradual, as opposed to on off...other than that it...

    Changing the speed of a walkman motor with motion

    Hello again everybody, Thanks so much for your responses. I'm sorry i didn't get back sooner, i had to rush off to Europe for a few days and my laptop managed to die on me. I've managed to find out how to alter the pitch of the motor. Reading this article gave me some insight into the...

    Changing the speed of a walkman motor with motion

    Hi there, I'm new here. I'm not very experienced working in electronics, although i love to experiment. I was hoping someone may be able to shed some light on a problem i'm having. I'm currently working on an interactive art installation. My idea is to alter a series of old walkman...
