My build progress

@fredrik Interesting, their US headquarters is 45 minutes from me. Looks pricy! So many colors!

THX for adding the link! It was late yesterday.
And I was too lazy to open the translator :). It is really a cool program. Many of my well-known build their panels in Inkscape, but use the Eurorack guidelines from the front panel designer program. If you e.g. you have created your scales, you simply save them as macro elements and you do not have to make them again and again, very practical.

Another VCF (5th) but this one with Hi pass / Low pass switch

a patch with it, sorry itā€™s a little long just for 1 patern, but when weā€™re in it time flies :grin:

A few parts arrived so I could finish up a second buffered multiple and some LFOs. I ran out of knobs againā€¦

No more holes in my first case thanks to some great looking blanks. Pretty stoked about it.



I put together a couple more FCUK buses and am starting in on a second case shortly.

looks like great progress . it is amazing how many knobs and jacks you can use up in no time at all .

@Dud whenever I see pictures of you and your stuff it makes me wish I lived closer to you because I want to be friends in the real world and not just the interwebs. I canā€™t travel though and itā€™s starting to look like IRL friendships are a thing of the past though so Iā€™ll take what I can get. :grinning: :sob: :metal: :stuck_out_tongue_winking_eye: :sob:

Yep. Two multiples use 20 jacks. Those things disappear quickly!

If you donā€™t want to buy the PSU from FC every time, here is a stripboard version that works wonderfully, I have it too. In this case AC IN is the 12v AC from the Wallwart. is super easy and saves a few more ā‚¬.

I made a small busboard from a piece of stripboard for it, super simple. And works.

Oh nice! I might just do that. After the next case, Iā€™m planning on a single row this could be perfect for.

I almost made my own PCB for the last two PSUā€™s but decided to go with the FC onesā€¦ May just do it for fun anyway adapting that with the extra two CAPS.

I want to do it with an integral encapsulated transformer too.

Looks nice, but no demo?

Awesome! I have a ton of questions. (I donā€™t work with AC a lot and most of my understanding comes from watching Mehdi Sadaghdar zap himself.) Is that a 240v AC only circuit? Are the 7x12s doing the heavy lifting in this circuit? My limited understanding is that itā€™s pretty much a full bridge rectifier with a lot of smoothing caps. In a 120v country, would I need fewer of the big guys? Also, does it matter which AC in is hot and which is neutral?

No, and it is not a 240VAC circuit either. You need to connect a transformer to it. So no mains is connected to this board in a direct way !!!

The board diagram should say 12VAC in. Using mains electricity with that circuit could be lethal.

So the ā€œAC INā€ labels are bollocks? I mean I could see using a step-down transformer to take it to a more manageable level, but Iā€™ve never heard that a regular primary to secondary transformer is going to change whether the current is alternating or direct-so does it?

Right, thatā€™s what I was thinking. Or at least, very uncomfortable.

Itā€™s basically just the Frequency Central design but laid out on a stripboard. Use it with a 12VAC wall wart or equivalent.

IĀ“ve updated the Picture in my post, should be clear now .

Jason are you North American? I think the term AC is often used unqualified in North America to refer to what I would call mains power. I can see why the diagram would confuse you if so.
