Hi everyone,
I wish to replace the analog Pots in my distortion pedal with digital
equivalents so as to control it in real-time from a computer. To
achieve this, I have purchased 1-wire Maxim Digital POTs -

The package I have purchased is a 6-pin TSOC.
The pedal I'm modifying is called a Turbo RAT -

I have built a few amplifier circuits before, designing and
constructing PCBs for them in the Electronics department in my college.
If I remember correctly, the package type of the amplifiers I used was
called DIP. When building these circuits, I used a socket for my
amplifiers so that I didn't have to solder on the opamps directly. This
way handy if the opamp was damaged later on.

I'd like to do the same again with the TSOC chip but I cant find any
sockets on Farnell for this package. What would you suggest? Also, do
people actually solder these devices onto pcb boards by hand? The 6
pins are so small...
Also, my plan for the digital POTs is to build a little PCB for each of
them. I can then suspend each little PCB above the pedal PCB in place
of the analog POTs. This will give me flexibilty so that I can easily
remove a POT and attack it to a different pedal - or whatever. The
1-wire master communicates with the POTs via a RJ-11connection, so I
will also place RJ-11sockets on each POT PCB. In addition, I will need
2 terminals on my POT PCB for power and I will also need to include
drilled holes so that I can wire the 3 POT pins to Pedal PCB. In other
words, the POT chip will sit in the center of its little PCB board and
the tracks will run out to the edges as required. How does that sound?
Is it a good approach?
Thanks for your help,
Barry.
