If you have Cynthcart, you may not know that a `paddle` enables you to control filter cutoff and assign another control on two knobs. There are a number of tutorials on this, but most of them are very convoluted with errors. So, here we go:
You Need:
First identify the wires that are connected to the female connector. You can do this using a multimeter and a wire placed in the relevent holes. The holes you need to hook up are: Pot1, Pot2 and +5v.
This site explains the pinouts http://old.pinouts.ru/Inputs/ControlPortC64_pinout.shtml
Now, solder the wires to the potentiometers making sure there with be enough slack to fit them into the enclosure. Both get Pot1/2 and the +5v.
Once they`re soldered, get the enclosure drilled with two holes. I used an old joystick base for my enclosure (It looks like a robots face!)
Attach the pots to the enclosure, close it and put the caps on. Test it, then you`re done!
*with 480k I found they only have an effect for 50% of rotation.
**make sure you have a connector that features the correct pins - the one in the picture is from a C64 joystick and doesn`t have pins for the paddle controls.
You Need:
- 2 x 240k LOGARHYTHMIC potentiometers*
- 9-Pin cable (female connector)**
- Enclosure
- Wires
- Soldering Iron/Solder
- Multimeter

Thank you for the description. I'm not so familiar with wiring diagrams. Am I right in assuming that the potentiometers are seen from below in your drawing?
ReplyDeleteThe diagram shows the knobs so it looks like they're from above but if you wire them this way as I did the controls will turn backwards (at least in my use case) so I recommend testing for your application. You can actually put 5v on either 1 or 3. It's reversible depending which way you want to turn the knob. You can test the results using a multimeter or a paddle test program in BASIC. It's about 4 lines to type in and available on Google. Good luck!

DeleteWhat happen if i use 250k logarythmic potentiometers?
ReplyDeleteHello fellow YouTuber, thanks for this info. I've built a fun device for an upcoming video (I'll be crediting you) but the 250k logarithmic pots (you can't get 240k) only bring the MSSIAH test bars up quarter of the way. Is that normal or am I missing out on ¾ of the filtering capabilities? Thanks in advance! Photos: https://photos.app.goo.gl/6nQ7R4tCxRImsseW2

DeleteIs there any reason you say logarithmic when the pinout you link to states "linear"?
