Green Dungeon Alchemist Laboratories


Hella legit guys, got this from Green Dungeon Alchemist Laboratories:

This is an exclusive video for Bands Play Synth, demonstrating the Obtruta MK1; an unusual analogue synthesizer and sound machine, filmed from the operators point of veiw by a camera strapped to my head (which is why it is a bit wobbly and out of frame sometimes).

This sound machine & synthesizer is now for sale on ebay!

Buy it with money and it could be yours today!

As quick as that, it is for sale! Place your bids now chaps and this device could be yours!

This is one of my sound machines, built a few months ago now but the idea behind it is so adaptable that I’m constantly developing it … do I even have shcematics for this!?

Just checked my files and yes I do! In the form of hastily scribbled incoherant notes :D

Technical details:

The core of this device is a 4089 frequency “multiplier” chip, which acctually divides the frequency weirdly- as I’m quite aware, that is just code for: Brilliant sound manipulator!

This archaic chip outputs anywhere between 0 and 15 pulses every 16 clock cycles, the number of pulses determined by 4bit binary numbers between 0 (0000) and 15 (1111).

Use the strobe input to control both the output and output-bar, and the cascade input is OR’ed with the output-bar.

Want one of your own? Then roll up ladies and gents and bid on the auction!
