any ideas for this?

just found this in my stuffs. Scavenged from an old photocopier years ago,

any use to it? like using it for a sort of battery indicator displaying in percentageX10^-2

Picture of any ideas for this?

Well the IC is serial in parallel out driver nice pic by the way.

You can get the datasheet for the BA823 IC here:


You can find the pin outs of the circuit board by following this Instructable:


And then you can make any thing that uses a 7 segment display.

There are lots of them here at Instructables.




It can be used for any kind of 8 segment display you may have need for. Just a matter of connecting it to a micro controller to run it. Just look up the spec sheet for the IC there.
