DIY Synth and Electronics Pseudo Silkscreening using "Lazertran"--How To Do This!

Image
I am still trying to figure out how to make low-cost, low quantity front panel silk screen art but can't solve that one out.

And: I have tried etching/fabrication services like Front Panel Express but find their CAD tools difficult to use and their services expensive for one-offs.

The good news: I have been using a water slide decal process to get me close to silk screen type front panel finishes using something called "Lazertran".

That's what this post is about. No, I don't work for these guys. This isn't an ad but it is the best way to do this I have found to date however.

So if you already have your metal work done and want to get close to professional looking, one-off front panel art,  for about $1-$2 USD per panel, please read on.

Still with me?

First, go out and get this stuff: "Lazertran."  You can find it online direct, also at Blick Art, Amazon, and several other online suppliers.  Your local art store may also have it, or maybe can order it…

QUICK ONE: Super Microvcf--8 components?

Quick one--

I am on a quest not sure why to find a VCF with the lowest parts count.  I could get one of those one Curtis chip clone solutions but that's cheating?

I created a long time ago a Vactrol VCF that's pretty low but I may have beaten it here....

I found this on the web.  8 parts!! It's from an old PAIA stompbox design.

I can sort of understand how it works I think, we are robbing current from the Op amp's feedback path, which changes the cutoff frequency.....but I was curious how it sounded, so I perf'd it.

I tried different cap values--anything from .01 to about .2 is worth a listen. The NPN can be whatever I figure, I used a 3904.  I used a 741 for the opamp since that seems appropriate for the era.

The 1MB values must be to not suck too much current out of whatever is feeding this filter I am guessing.  I didn't mess with those values, but overall, parts values are not critical; from messing with this micro circuit the caps can be different values f…

Creating Custom GUI Elements in Reaktor 6

Putting down the soldering iron this week to focus on software that lets you DIY your own FX plug ins--Native Instruments Reaktor.

With Reaktor 6 you can whip up synths and what not, I feel Reaktor synths usually sound a bit thin, but for recording projects, Reaktor is VST duct tape, used to solve simple and maybe not simple problems.

Need to flip L and R channels in a WAV file?  Reaktor can do that (it's easy).  Need to make a stereo WAV into a mono file and control overall volume of the result?  Easy.  Need to rerecord a stereo file as mono, add EQ and a tape delay, then use the whole Mishpucha as a VST in Ableton, and then loop it?  You can do this with different software, but Reaktor makes it really easy.  Those are some damn clever guys at NI. Audio duct tape!  Yeh!!!!

For instance: I did a session the other day where the DJ dude wanted a drum roll that started at normal speed and slowed down in a controlled manner. There are probably 100 ways to do this, but to see if I coul…
