Alarm Clock IC

[Grogberries]

I was dissecting an alarm clock I used to use and found a LM8560 IC. It looks like it's for controlling the alarm clock functions (makes sense right) but can this be used for something audio?

looks like it is the alarm clock

Yus yus, but can I use this for an effect? Or do IC's not work that way. I don't know too much about them.

that should have said " IS the clock"

well being as how its a clock you can possibly use it to "clock" something else, maybe add a pot somewhere and make it adjustable, but a 555 would be easier to work with. it might be that the timing is actually based on the power coming from the wall and not very adjustable.

if you are looking for madness i'd say grab an audio probe

and start probing around for some audio and then start bending it to get different oscillations or whatever.


don't leave it plugged into the wall, or you could die.

and i’m pretty sure you can also bend the display. i’ve done it myself. and then you could use Mike Ford style as a sequencer for a photo cell controlling a bend or another device

ah neat. what exactly does the capacitor do in the probe?

ah neat. what exactly does the capacitor do in the probe?

It blocks the DC offset of the signal.  If a signal within a device is offset to a certain voltage (very common, say +4.5V as is often the case in circuits that use op amps on a 9V supply) then the capacitor blocks that offset, so that you won't damage what you're plugging it in to.
