External Pot Control Console

Here's the control console I've just built:

http://inactivex.bp6.com/080-c64-&-controller.jpg

It's connected to the C64 using a 2-in-1 plug that I fashioned from two individual connectors. The plastic sleeves were cut to fit and reassembled in one case, using some extra plastic:

The connection, a tight and stable fit:

The pots are linear 100K, used with 4700pF capacitors.

The connections between the C64 and the control console are fully wired to all 9 pins on both connectors. This is in case I decide to add more functionality to the console at a later date.

Re: External Pot Control Console

What did you build the pot box out of?

Re: External Pot Control Console

It is a general purpose console box from Maplin UK. They do a few sizes, and you cut the holes you need and install everything as you'd like.

The boxes come with a plastic sheet attached to the top which is handy for marking where the holes are to go before drilling. This is then peeled off prior to attaching the pots, giving the shiny metal finish.

I've got a little 8-channel mixer (nothing flash, just loudness level controls) in a similar box next to it.

Re: External Pot Control Console

Here's a diagram of the circuitry:

Numbers correspond with pins on the joystick port. This circuit was constructed twice for using with both C64 controller ports, and all four potentiometers.

Re: External Pot Control Console

You are using 100k pots... how is the pots response compared to the 500k pots AlphA suggests ??

And if i may ask, what are the 4700pF (caps?) for ?

Re: External Pot Control Console

Actually, i did smile but only found external articles with theoretical discussions of how to make the pots more responsive - like this one http://sound.westhost.com/pots.htm (see fig.9) and all i ever heard from forum-users was '500k' wink even when i played around with feedback the answer was '500k - only works for the last 1/3 of the way... live with it' .... hehe, Alpha suggests 500k also, so i thought this was some groundbreaking discovery - like that guy who removed R8 from his S2S earlier today *LOL* now what was his name wink

Thx for the link ron smile

Re: External Pot Control Console

thanks worked for me perfectly as well, 100k pots with 4700pf capacitors work so much better than 500k.
shame your console looks so much nicer than mine!

Re: External Pot Control Console

The console's surface soon looked a bit grubby with fingerprints, so I enamel-painted it a nice "Breadbin BrownŽ" colour. Also shortened the pot shafts.

Still looking and working great!
