KORG Octotron Auction Ending Today!

(Source: lofifuture.com)

Here is my first sketch of what i want to make of A Casio SA20

Proposed features: 2 555 LFOs (patchable)
Delay section. 
MOD section (just the circuit bends)
Small patch bay
and a built in 5” oscilloscope (from a bent portable TV I’ve had laying around for too long)

Sorry about the crappy pic, need to get me a scanner!

Today’s repair

Going to be busy today guys, got 3 projects to work on. First of all I just got this Hiwatt cab in for repair, depending on how interesting/repairable the problem is I may make a video on this one. 

On top of that I’ve got the Akai samplers breakout cable to finish soldering and the KORG Octotron sequencer needs some pots replacing before its final assembly. 

I’ve got 2 weeks off college now to expect a lot of posts!

Korg Monotron paired with an 8 step sequencer: The Octotron

I decided to put the External HDD enclosure to the side for a while and use this wooden box instead. I’m making a top panel for the Monotrons controls and all the CV patching out of clear acrylic. The 8 step controls will be on the front of the box. The battery packs will be mounted on the underside of the box witch will be raised by four feet made out of circular cut offs. Since the only battery pack i had for AAA batteries was a 4 cell, i modified it to act as 2 dual batteries. I’m adding a switching circuit so you can select witch bay the monotron is powered off. great feature for live situations. The sequencer circuit is hidden in the box on its PCB risers. Expect a lot more progress tomorow, im working through this build quite quick.

I removed the old wall mounted TV signal isolator for our old NTL box. Seemed a shame to waste the old enclosure so i built a Voltage controled oscillator into it. Pitch and volume controls with CV in and audio out.
