20 char of i second this lolol
oh all right you win , your stuff always looks cool !
Iām wondering how you fastened the tube holder and the āmirrorsā. Could you maybe upload a picture taken from the side so that we can see the modules inner parts?
Yeah, finished my GRR yesterday and itās Funky
Today I finished my first Kosmo stripboard module: the Twin T Kick Dum from @Dud. It was also the first time I made a front panel from aluminium and Iām quite happy with it. At first I wanted to paint the panel black, but the aluminium panels have a brushed look, so I decided to leave it that way and just stick some white labels on it.
Looks great! Can we hear it?
Hereās a very small demo. I had to trigger it by hand and hold my phone to film it, but at least you can hear how it sounds.
I will also try to make a little drum machine of an esp8266 board I have lying around. And when my Keystep Pro arrives, I will make a new demo.
Hi @Jos, I wanted to keep things simple and tidy but it turned into a nightmare on the inside
The 2 large stand-offs and the valve consume a lot of space. I struggled to fit everything inside and had no pot that could be mounted directly to the 5mm thick front plate. If I make a 2nd Iāll do things differently.
Another not so clever idea was to use the 2nd half of the op-amp to make the led flicker. The strobe effect is quite audible which cannot stay like that.
One year in
I still need to work out what is up with my first megadrone(not shown) and the 1113 has never seemed right.
But happy with where I have got to in a year.
Did you end up building that MFOS log/lin vca?
Iāve got the Electric Druid āVintage VCAā on the breadboard about to test, wondering if I should try the MFOS as well. Trying to build with non-specialty ICs whenever possible.
Iāll be doing mine fairly soonā¦ going to finish the VCO and do the LFO first though.
I kinda feel the same about specialty chips. Iām sure theyāre good but the old school builds are rewarding in their own way.
I had used a flickering led its internal so no omp amp needed . havenāt noticed any noise.
Yuup, its done!
This is the temporary panel layout so that I can screw it into the rack until the right one is ready.
It works wonderfully. I didnāt build it on a stripboard, but on a printed PCB that a friend gave me as a gift. It worked immediately without adjusting anything, really very well and normal components TL074, 2n3904, linear potentiometers and resistors, nothing unusual.
I started my module-building journey shortly after UK lockdown started last year - this after a long break from doing circuit building and electronics, and it was great to get back into itā¦
ā¦ however I found myself building module after module and without a case to put them it, the only way I could do anythign with them was to jerry rig something up on the workbench each time I wanted to try something out!
Having got bored/frustrated with that, I (perhaps a little later than I should have) decided to build a case and put the modules in place.
Results in the pics - first modules, first case. Power supplies are built and will be installed next, once I get some round-head screws instead of the flat heads Iāve used for now.
Very excited about having this ready to go at any time - I should have build it sooner!
It makes me so happy to see all these monstruous KOSMO machines popping up in the world!
I just spent some time squaring things off with the new top piece and checked the rails would fitā¦ one might need a little sanding down but ill do that later.
It was nice to check everything and have my first āIt feels like a thingā moment.
Progress is slow, but rewarding =)
Modular synths and woodwork are ace =D
Your ā1 year inā looks WAY better than my Kosmo 1 year in!
Everything sitting on the top, minus the AO module doesnāt work properly and/OR I am too afraid to plug it in to find out. I think thereās something like 7 or 8 modules that need diagnosed. The module with the mess of wires on top was one of the first ones I made but Iām too afraid to plug it in. Itās the BMC User Writeable Quantizer in Kosmo format.
Sitting there itās uselessā¦
Plugging it in will give one of two results :
- it works, yay !
- it doesnātā¦ well it isnāt more useless than just sitting in that boxā¦
Since I finally gave in and got an automatic wire stripper figured I need to catch up on āfinishedā modules that were waiting on wiring:
So both of my homemade 3340ās are now working!
Also pictured the 3 k25ās that are done.
Still need to finish wiring my Yusynth ARP4072 and see if it worksā¦maybe tonight.
