Olegtron 4060 mk2

OVERVIEW Olegtron 4060, originally released in 2013, has been updated to a MK2-version. The semi-decennial celebratory release, altough wearing a new colorful plumage, is pretty much the same machine inside. This means that the tutorials and demos will serve to the users of the 500+ original units, as well as users of the new one. Many improvements have been made, though - thanks to feedback from users of the original version

UPDATES new features:

Four 3,5mm TRS stereo connectors for a maximum of 8 signals in/out

Large color coded patchboard

Changeable patchboard elements: if the patchboard becomes loose, you can change the connector elements to fresh ones

Integrated 7-bit saw generator: buffered saw and ramp outputs

Power input socket: a standard 2,5mm center positive barrel type power jack.

Power LED to make sure you will not leave power on accidentally - the LED also starts to flicker when battery is weak

Buffered virtual ground

”Link sleeve”-jumper in the front panel for setting the working range:

Link to – (battery minus) for unipolar 0-9v range

Link to G (virtual ground) for bipolar +/- 4,5v range

Trimmer for setting the working range of FREQ-potentiometer in the front panel

A socket in the front panel for adding a frequency capacitor

Bigger knobs for better precision and comfort

OSCILLATORS It's a compact oscillator / frequency divider box capable of creating signals and sequences throughprogramming method: sticking electronic components to it’s patchboard! The device can be used as a standalone sound generator or as a control voltage (CV) signal generator to a wide variety of machines, such as modular synthesizers. The name of the device comes from CD4060, which is an integrated circuit, a "chip". It belongs to a series of CMOS logic chips called 4000B and interfaces with other chips of the series seamlessly. The series dates back to the sixties, but is still relevant in sound electronics and DIY. The CD4060 contains an oscillator with adjustable frequency and a frequency divider, that outputs 10 different subfrequencies.

Olegtron 4060 is based on an RC-oscillator example from the CD4060 datasheet, with the addition of a current limiting potentiometer that kind of simulates a weak battery. The rest is mostly user interface design, highlighting of course the innovative patchboard that makes a good playground for experimenting.

USES

Stand alone sound generator: plug into your amp or headphones (start with low volume!)

Synth control: send CV, clock and gate signals to your synth and from the synth to 4060!

Circuit bending: trigger toy buttons, modulate pitch and more...

DIYer's test signal generator

Sound manipulation: feed amplified signals to 4060 and output them with a no-fi flavor!

Light sequencing: connect single- or multicolored LEDs straight or via a driver

Combine above uses and keep everything in the same fluctuating sync
