555 Oscillator mod

I added a couple of mods to my 555 oscillator:

1. a volume knob
2. a switch that jumps from "standard" astable mode (see previous video) to "pseudo trigger" mode, in which pins 2 and 6 on the 555 are connected via a momentary switch-- pressing the switch completes the circuit.

The layout (according to the orientation in the photo above):

The jack on the top right is the power (up is on)

The pot to the left of that controls the frequency

The jack below the on/off switch is a control voltage input

The button below the CV input is the pseudo trigger

The switch to the left of that selects between astable and triggered astable modes

The pot below the switch is the volume control

The jack next to that is the output

Here's a video demonstrating the mods in action (w/ a Frostwave Resonator):
