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.
