I played around with my TI 83+  and some other hardware i got from somewhere. this is what i made:



I connectet my calc to some divices which are able to play sound (my sister's cd-player, a digital projektor of my school and some hardware pices of mine) and it worked. (my class mates are taking me for crazy)

In generall, the output is to quiet, so i need an amp or a louder speaker. I prefer an amp and tomorrow i get an old, non-working laptop. i think i could use some hardware of it but i need help. so if anyone here could help me build or get (from the laptop) an easy and hany amp, this would be very great.

EDIT Sorunome: resized image

i know:P
but also there are some other elements which ate interesting like the inputs. or generally to open a laptop is inzeresting

haha lol yes this would be nice. i just need to connect them......

niiiice!
