Variable Clock v4

The most advanced version on the "Variable Clock" family!

This is a variable clock output device.
You can manipulate the speed of the Game Boy processor on the fly with a potentiometer.
The pitch of the sound will become lower as you slow it down and it will become higher when you speed it up.
You can make some incredible sounds with this kit as well as adding a whole new way to play games!

Built in features:
-On/off push button switch:
No need to get a separate switch for this kit. It is built right into the PCB!

-Panel mounting:
This kit should be mounted directly the Game Boy case with the provided screws and spacer.

-High limiter:
This will limit how fast it will go. Many devices will crash if pushed too far.
A 10K SMD resistor is pre-soldered for installation into an Original Game Boy(DMG) or Game Boy Pocket(MGB).
It can easily be removed with a razor blade and you may install a different through hole resistor(an 8K resistor is ideal for the Game Boy Color(CGB).

-Low Limiter: With a 100k-500K pot(higher resistance = lower speed and pitch) this kit will go so slow and low that the LCD will not be visible and the notes will sound like a droning "growl"(this can actually be a very awesome effect for music). The VCv4.5 comes with a 200K trim pot pre-installed. This will allow you to set the low limit before you install the kit or you can install it at the top or side of an Original Game Boy(DMG) and the low limiter can be accessed through a small hole with a screw driver so that it can be adjusted on the fly. Check out this video for a demonstration of how this feature works:

You can purchase this as:
