First of all:
Hi my name is aron and i found out about your forum something like two weeks ago..since then i got myself a couple of books about basic electronics and i think i make good progress.
BUT: reading about you guys building so much nice stuff i just cant keep my hands off of it.. :
my first project:
a passive preamp to control the level of my monitors (as i wanted to buy one anyhow)
what i´ve learned so far is that i wont go with any potientiometers as my stereo image might differ i also found out how high the impedance for the attenuator has to be (10k) (please excuse my possible misspellings its hard for me to learn electronics in english but i do because of the bigger support)
also i already found out about
http://www.goldpt.com/r_series.html to show me the resistor values needed
BUT! i just cant seem to find a part like this to build the attenuator
http://diyparadise.com/stepped_atten.html
he talks about some kit but the links are dead..i dont mind finding all the resistors myself but i just cant find something to mount the stuff on
am i right that this blue part would be called encoder? or is that only something thats sends out a singel once
..
what i found so far is nothing more than this
http://www.reichelt.de/Rotary-Pulse-Encoder/STEC12E08/3/index.html?;ACTION=3;LA=2;ARTICLE=73923;GROUPID=3714;artnr=STEC12E08
but how can this be 24 steps if it only has 5 pins?!
i want the preamp to:
-be passive
-have 2 unbalance in and outputs
-use an attenuator (be controlled by 1 attenuator)
-use highquality resistors (thats why i want to build the attenuator myself)
can anyone recommend a starting point for the attenuator?
