Yeah, that is suggested. Check this out:

Yes I think that is the one that I ordered! I only want to piggyback it. could that still work?

Did you see this?

The switch can just connect and disconnect the output from the LTC module to the clock pin in your gameboy. There can be glitches but it works for the most part if your switch is fast and clean.

A step up converter? Are you just using one of those LTC PCB kits or what are you using?

So I got a really small 300k pot and a step up converter. Please feed me some ideas. How would I wire up the interrupt switch? Does a trim resistor necessarily have to be small, or can I make it up using a 100k? I have lots of random value resistors from scaving when I used to circuit bend stuff. Do I have to join some kind of secret society to unlock hidden answers? Come on guys.

It was years ago, but it was this size:

These are smaller yet and I use them  quite often in other projects:

That one can be bought with metal, plastic, smooth or knurled shafts. The values linked are obviously not correct for your project tho.

@ Jazzmarazz What size pot?
@ Analylogiq What size pots, What size resistor? Please explain this "theramin mode" it sounds cool.

I've done it with two pots and a light resistor
one pot with an interrupt to switch between normal or vari clock
second pot for fine tuning
plus a light resistor enterlaced in a switch to turn on light theremin mode

all this is fitting on the right side of the batteries when you face the gb

find small pots
taaake your time
and fit them anywhere you can

I did a couple with a pot in place of the internal speaker.

Has anyone had experience installing this mod? I was thinking of using the same point for the +5v on my backlight. Is this possible? I don't suppose there is room enough in the case for a potentiometer? If anyone has input about this, it would be appreciated!
