Tiny Vintage Reverb Tanks

One thing I noticed when looking at spring tanks is most of the small units are plastic. I happened to find three of these all metal vintage 1970 ones. Not shown; I refoamed the center dampener and freshened the glue attaching the transformer cores/coils. Here is also a 1970 IC amplifier magazine clipping making reference to these tanks.

On a side note have you ever looked up the history and science behind the spring reverb?

UPDATE: I did fond a Local source of magnets with the correct polar pattern for DIY spring reverbs. (SM Magnetics)

Grass Click-Tone Control Audio Stimuli Module.

I recently picked up two of these Grass Instrument Co. Click-Tone Control modules. These units have 1994 date codes and still work. From my understanding these would be used to provide test subjects audio stimuli for studies involving things like rhythmic auditory–motor entrainment, but I want to try to get it to make some music. The port on the back of the unit allows you to remotely control the output. I am hoping I can make some sort of sequencer for it and experiment with some of the internals. After briefly looking at the board it appears to be based on a pair of XR 2206 IC Waveform generators.

Step Seq. anyone?

Complex Subjectivity

I love making art that has multiple views to it. This complexity allows for a wider range of interpretations. A prime example is some of my reactive resin artworks that look different in regular light, UV light and in the dark.

Reused burl for the base, resin, glow pigments, florescent paints
marble chunk base, coated in glow pigment/base then feathered strokes to make holes.

Please take care of each other.
