My build progress

My first PSU was also from Frequency Central, then I needed another one for the workbench and built it on a stripboard, as Sam always says, Cheap as Chips! Here is my layout, easy and works great! When I get the chance, I also draw in a few LEDs.

Konversion of an NLC Sloth Chaos. I actually soldered this up weeks ago but it didnā€™t work and I put it aside to work on other things. Today I finally took another look at it and found Iā€™d completely skipped soldering one of the IC socket pins. It works now. Definitely chaotic, I think itā€™ll be fun to play with. This is the regular (1 cycle every 15 seconds) version. Maybe Iā€™ll do slower versions at some point.

More 25mm modules! Nice!

That moment ā€¦ when you see your own modules in your own rack for the first time and you can be damn proud that everything is self-made!


Before it was nice too, no question about it, the green box will never be dismantled either, it was the beginning.

And without Sam I wouldnā€™t be at this point now, so THANK YOU Mister Battle :heart:

Itā€™s a damn small PCB! The Eurorack version is 4HP.

DANG! Looking really nice!

For a moment I thought you had combined a few elcoā€™s (the black ones) by connecting them in an alternating polarity fashion (pos to neg and vv.), but that is not the case, or is it?

As a finished module it should cost $ 85 !!! What did he solder it to? With gold ?!?!?

Special Australian solder?

The PCB was $8. Parts, well, one TL074, two jacks, a pot, a knob, an LED, some resistors and capacitors. Maybe four or five bucks? Front panel I made from an aluminum blank, $2. Plus postage. Say $20 altogether. I didnā€™t time myself but Iā€™d guess the PCB took me 20 to 30 minutes to assemble, jack wiring another 15 minutes. The real time went into laying out the panel but if I make others I wonā€™t have to redo that. Drilling the panel holes,10 minutes? Applying the paper and transparent plastic to the panel and cutting the holes, 10 minutes? Omitting the panel design and allowing some extra letā€™s say it was 90 minutes work. $40 an hour, about.

Please let me know if you have spares!!!
I breadboarded Torpor a while back and it only sorta workedā€¦ lol

that it is not - they are each separate!

I bought the PCB from NLC, the panelā€™s a one-off.

ohhh gotcha!!
NLC makes super cool stuff - I really want to grab some of their 1u tiles - that little itty bitty sloths is what i actually want haha

I was tempted to do my own PCB about a month into the COVID-enhanced delivery time from Australia but my patience was finally rewarded. (And delivery time should be much faster these days.)

One Cheap, Hacky Audio/Visual Synth!

I know some of you have heard of it but for those unfamiliar itā€™s basically a CD40106 based oscillator bank with a few extra patchable goodies like LDRs/vactrols, a couple pots and some external ins botched onto a cheap VGA test kit to make a rudimentary semi-modular video synth thing.

Hereā€™s my first wiggly pic:

I have absolutely no idea what Iā€™m doing but Iā€™m having a good time!

Iā€™ve been wondering about that. It looks pretty fun. Iā€™ve been low-key curious about video synthesis and this seems like a good intro, but Iā€™d love to be able to build an actual module or something out of it to translate signals from other modules into video.

Give it a go! itā€™s an easy build and is fun so far. It does have 3 ins/outs so it can interface with other modules, though I havenā€™t tried it because my kosmo is in pieces ready for some case surgery tomorrow.

I thought about trying to make this into a module too - itā€™d be pretty cool and runs on +12 so would be easy in that sense, but the difficulty would be getting all the patch points onto a panel. Thinking about it now, thereā€™s a few little things you could do to get an easy panel on it - mount the VGA tester on the back and replace the slide switches with normal toggles and you could stick a panel straight on the front. Youā€™d just be left with having to wire up about 60 patch points to jacks which I donā€™t fancy, though you could easily be selective about which you need.

Yeah. Iā€™d even consider just mounting the whole thing to the front of a panel. Itā€™s on my list. Gotta get a few more projects done first and pick up a couple CRTs. (one to make a bad oscilloscope out of)
