Wave Runner

Wave Runner is a multi-waveform sync-able LFO based on the Electric Druid TAPLFO2D family of

code, but with some significant additions and improvements. The TAPLFO2D-FC PIC is not

compatible with similar modules, and was developed specifically for the Wave Runner.

Please note that the Wave Runner PCB incudes pads for either 9mm pots or 16mm pots. If you're

using my 4HP panel you'll need to use 9mm pots. Be sure to install them into the correct pads,

indicated by boxes on the PCB.

Oh yeah, you'll see on my build (below) that I used B10K pots, just because I have a metric shitload

of them – Wave Runner is not fussy, you can use B10K, B50K, B100K etc. I mention this because in

the past I've found that a few stores seem to be regularly out of stock of B100K.

Do you have a question about the Wave Runner and is the answer not in the manual?

Page 3  Mount the two highest sockets (LEVEL, SYNC) onto the panel with the ground tabs pointing upwards.  Use a resistor leg to connect the two socket grounds to the bent leg of the LED, allowing the resistor leg to extend out from the panel by 15mm or so (see photo below) ...
Page 4 LFO socket is spot-on at 0V when the Level CV input sees 0V. This is particularly important when using Wave Runner as a pitch vibrato source into a VCO with a mod wheel controlling LFO depth via the Level CV.
