Yeah, one regulator’s tab is connected to ground and the other to 12V. They have to be on two separate heatsinks, not touching, or smoke will come out.

@analogoutput @zorch don’t worry guys I knew it! I took care of isolating properly the two regulators with isolating thing on the heatsink and put plastic nuts on the screws so both are fully isolated! Look closely on the pic

But that means you don’t have very good thermal contact with the heatsink. Plastic, like most things that don’t conduct electricity, also doesn’t conduct heat very well.

I don’t know, I grabbed that thing from a switch mode power supply so I guess the thermal dissipation should be okay 
If it gets too hot I’ll buy some new heatsink

Just do what I did and cut it in half! I have a jigsaw, but a hack saw will work fine too.

Wait if I use that kind of tool I will definitely cut my hand haha I’m too clumsy 
Don’t be scared to try it! What’s the worst that could happen? You have another hand, right?

Hahahaha yeah I know well I’ll try it out later if I am able to use my dad’s tool

Today i’ve finished a triple vactrol “VCA”
my last module for this case : the @analogoutput quantizer, i’m a little affraid by the code party but i’ll start to solder it tomorrow

JFDI and move on to the next case. How many now? (Photo op)

Might just drop this here… got to make some boop.beeps with the beatstep this evening… no VCA or ADAR… literally just an LFO controlling the cutoff on a MS20 filter

Side note, I don’t think my ms20 filter is working properly. It seems no matter what one LED is always on.
i’ve just soon all my module (not tested !!!) for case 4 … but no case 4 at all for the moment, i have to wait for free wood
i find that’s take so much time but it’s free, so i wait …

Even with the Resonance potentiometer at zero ?
Yeah… its a weird one

I still can’t figure out how the filter works or if it is working right and its been months and months

It seems to work, like I can hear an audible change when I adjust the resonance and the cutoff point clearly adjusts the frequencies that are audible.
I’m hoping that I can pick up my scope tomorrow and see whats actually going on

@GhostBassist the led are used like clipping diode, so they should shine only when the resonance is increased, there is indeed a small problem somewhere
have you put the 2 leds on opposit polarity ?
maybe we can continu this topic here ?
The isolating material used in power supplies has a low thermal resistance and a high electric resistance, so they are ideally suitable for this task. In fact they were made for that purpose. As a matter of fact you will find them a lot in power supplies and audio amplifier power stages.
