Hex Box V3 Video

Short demo of the Hex Box V3 in action!!

Hex Box V3

I could not resist the urge to transform this vintage volt/amp meter into a unique one of a kind instrument.  Based on my previous circuits, this Hex Box is the latest version.  I was able to use all of the existing construction of this meter without many physical changes, most notable is the power input and audio output jacks.  Circuit is based around the CD40106 IC, running with 4 oscillators configured into two pairs.

I decided not to repaint this and keep the original patina.  The meter is connected to the power side of the circuit and reads the current draw.  However, due to the range of the analog meter, the readings are not accurate, but it gives a nice effect.  Unit is complete with power LED, on/off switch and volume control.

Videos to be posted soon.

Video showing with working 40106 based synthesizer unit.

Pictures of the latest creation.  Runs with 4 oscillators (wired as two pairs), volume control, 1/4" output jack, standard 2.1mm 9VDC supply power (low mA draw). Delay is outfitted with a delay time control and also a repeat control.

Together, both circuits complement each other and endless drones and textures are created.  I will post a video later.

The industrial finish makes for a nice clean look, I will change the hardware soon.

Well, it's finally finished.  I combined my hex drone circuit with the delay circuit of a PT2399 IC.  I will post videos and pictures shortly.

4 oscillators, delay and repeat controls too.  Amazing sound from this hand held/table top device.

Stay tuned!!

New Project Drone/Delay

I have a circuit made that uses the Hex Drone Box sound base running through a delay circuit based on the PT2399 IC.  Makes some amazing drones.  Sound (square wave based) section is set, made some adjustments to the Separation portion and changed the frequency range.  Delay side is still in the works, but nearly complete.  I looked at a lot of different arrangements of the circuit, but ended up basing the design around the original schematic found in the specification sheet.  Of course I added a few changes :-)

I will post a video soon of the initial work.
