Project overview
Tremolo Factory Rhythmic has all its well-oiled machinery ready to produce a ton of tremolos effects with complex patterns.
Introduction
Are you up to this new industrial revolution? The purpose of this factory-board is to maximize the assembly of as many complex tremolos as possible. Now join us on this factory tour to observe the line production processes at work:
Via toggle, you can choose if either 4,6 or 8 potentiometers send an impulse to a decade counter that hits an optocoupler (or white clear LED and LDR – Easier to source) and then goes its way back to the Tremolo circuit. This awesomely unique and straightforward take allows you to manufacture your own patterns with a minimal amount of easy-to-source parts. The second momentary footswitch resets the pattern, so you’re not starting in the middle of it when engaging.
For a circuit test, the LEDs need to be placed in the PCB, or you will not get any Tremolo going on. We recommend using at least one metal shaft 9mm pot for the speed control, or the PCB will be held in place only by the toggle. We tried using 3 metal shaft 9mm potentiometers in our build. Another thing to keep in mind is that these 9mm plastic shaft pots require precise drilling and should be soldered with everything in the enclosure to allow a smooth rotation.
Now that you have seen how the making process works is your time to build this industrial setup. Are you ready to have a workshop of unlimited tremolos mass production in your own house?
