Yes, you can distribute the 5V over several busboards.
Just keep track of the overall current draw, but with 1 amp of 5V available it is unlikely that you need to add another NoDrain adapter.

Hi,
Nothing like a word from the man himself to confirm things!
Cheers.

You’re doing good things, I love the dual waves!
The idea of the no drain, obvious but nobody else as far as I know does it that way......hopefully I’ll have it by Tuesday.

Isn’t she a thing of beauty!
Free case made from off cuts laying around......
Made a pair of wings onto which I fixed the original box.
Couple more rails, from the doepfer diy kit.
Just needs a back and top panel.
Pleased as punch, even though it’s a rough hand saw job!

Tried to get this in my sig, computer says no.
Link to my YouTube.....so far 3 recordings from my rack at various stages of completion.

Later tonight a fourth video will be put up.

Hopefully somebody else will enjoy my shenanigans!

So I read the wiki link for this dude.....
I’ve literally just heard of Pere ubu!
(Although I didn’t actually hear a thing, strange turn of events that is!)

Listening to variation on a theme album....turns out you tube was my guide.
It’s a bit like the syd Barrett (solo or with pink floyd)
Meets the jimi Hendrix experience with guest appearance of David Bowie.

Yes I’ll give pere ubu a whirl in a bit........
Cheers cptnal.....

Now it looks like this!

My first eurorack module diy build, complete with 1 SMD component.
Fitted tested working!
(Maybe beginners luck :hmm:)

But happy... :guinness:

Way to go :-) - it's fun getting to know the other side of the modular.

Building the zlob MIN-EQ

Image


Image

This went together quite well.
Easy enough, but I had to look some parts up.
Some stuff was by a process of elimination, the rest was straightforward.
I did have to think about some parts but overall nice and simple.
Which took a couple of hours for me (but I’m fairly new to this).

Really great little module!
Works exactly as described.
Improvement to my rack.

Thanks!
Yes it is......
I started out with an Atari punk on a breadboard!
So be careful.......this could happen to anyone :hihi:

Inspiring posts, thanks, JAR.

I'm just beginning DIY - it's the only way for me, as I'm down to 0 cash for now.

- check chip orientation
- check height of components before adding front plate
- don't melt the black plastic

have learnt from all mistakes above

Wow!
Glad I inspired someone.....
Was not expecting that (what with being bottom of the stack and all).

Tonight is noise2 build night!
Hopefully this build goes as well.
Fingers crossed and all that.

Moving on;
My plans for the future.
Erica synths adsr and expander. Killer envelope.
In the post!

Not 100% certain with two modules, but I like the look of the Felix buffered attenuated mult. (Planning on using it as an lfo adjuster.) basically buttoned to the doepfer a147-2 to give some control over the outputs. Sine and square in particular.

Also omsonic dual vca. Cos you know the mantra around here!


Image

What do you think? Have I done anything stupid!
Two or three modules of interest;
King slender. Harvestman.
Pluck. 2HP.
Xaoc Tirana II

Might need a third rail!

Building Bastl N2

Post by Just another rookie » Sat Jul 28, 2018 1:10 am

Started this on Friday at 19:05, including a couple beers, a couple smokes and a dinner break. The second board started at about 22:20, the module was running in the rack by 23:40. If I had got my head into it no mucking about, I probably could have built it in half the time.

Lovely kit to build! At first look I was a bit daunted by the parts count but, each section was individually bagged, top board, bottom board, assembly.
Most parts can be fitted by process of elimination, there are just a few resistors and capacitors that are 1offs, I had to look these up.
The build doc was useful.

Image

Image

Great stuff! But now what.....I didn’t think I’d have these built quite so fast.
:hmm:

Just under £35 for the tools required. Bargain!
(Solder station & pcb holder £25)
(Flush cutters £6)
(Smd tweezers £3)
The tweezers turned out to be very handy! Used/Ill used these way more than I thought I would.

Happy days.

This arrived yesterday!

Only had a five minute fiddle, it works! Is basically all I can say at present.

Oh dear.....or is it!
Couple of nice things in a box!
More diy;

Music thing, spring.
I think (digital only) as I have a block in a box.....why not have a go?

bastl propust, simple drum filter. That’s the plan anyway.

Befaco attenuverter

Little bipolar jack light.

Image

Future plan, changed again! Nothing like the original.

Bursting at the seams!

Erica synths diy delay in the post!
Stupid move.
10hp left, decide I love the idea of a 14hp module.

I really need some kind of dedicated simple envelope/vca for drums.
Doepfer envelope controlled vca seems like the current choice,
but I’m considering bastl skis or patching panda punch.

And perhaps a new case! :deadbanana:

Catching up with the baglog of uploads.......
To keep it chronologically correct;

I built the analogue solutions business card.
Few quid in parts. Hardest thing to source was the Motorola LM1496.
The 4558IC has a temporary op amp dropped in (meant to order but forgot)
I guess that’s why diy gets expensive! Postage costs!!!!

Image

Not sure exactly how to calibrate this (modulator balance and signal balance)
Had to make a lead, broke a pull restraint. Need a better technique!
A vice was too brutal. Hour to build including picking parts!

Still need a panel. It appears to work? Need to read up on ring mods!
What I’ve learnt so far....transformer circuits. Not this circuit.
Luck needed I think.

Moving on, 27th November
Bastl propust! Nice quick little circuit. Hour to build.
Built this to quench the thirst! Had to solder something......
Strange urge. Dealt with!

Built tested used loved. Great thing. Simple passive device.
Building.....
Image

How it works.....
Image

Used this to shelve my drums.
Hats top filter (hi pass)
Snare middle filter (band pass)
Kick bottom filter (low pass)
Yes I’m pleased with the results.

These outputs I feed into the Tritone, hats hi, snare notch.
Here I break the normal (middle switch on Tritone) and send this through the chronoblob. The kick goes through the lo filter of Tritone.

Cheap and effective with only one caveat. Signal loss.
However in use;
The signal loss of the bastl is useful in that no attenuators are needed before the Tritone (nice bonus, it’s easy to overdrive the Tritone!).
It can really scream! So in my use case this is a non issue.

Video of this idea will eventually end up in my usual place.
Crispy drums! (Or better than before I think!).

Whatever next?
