Stripboard Layouts for the LMNC PCB Projects

Hello All!

I hope this is OK to post on here (please do delete it if it’s not appropriate) but basically I’ve made a few of the LMNC PCB projects into stripboard layouts for people on a tighter budget.

I’ve been following Sams vids for a couple of years now, and love his stuff. I started my DIY modular journey with his simple VCO/VCF… The rest is history.

I’d planned to buy some of his PCB projects he’s been releasing, but I stupidly chose a smaller format that doesn’t adhere to any standard whatsoever (apart from +/- 12v) so I won’t be able to get any of those for my modular until I build a new case… :frowning:

This made me make the decision to convert a few of them into a stripboard project so I could fit them into my smaller case. I started with a VCA, as I was already planning to make a VCA of my own with the AS3360 chips - but Sams schematics made this much easier. There are a few more projects too, like an ADSR, drum sequencer etc… I’m planning a few more in the near future too.

I’ve posted all of my stripboard layouts for these up on my website; duskwork.net

Let me know what you think

I don’t think there are any objections. Most of Sam’s projects were available as strip board before he started doing the PCB versions anyway. If you want to share with us (and you’re not really trying to funnel traffic to your own website) you can feel free to post the stripboard layout images right here in the thread (like this for your VCA):

That’s great; thanks for uploading it here. First time on this site so I missed the photo uploader!

If anyone has any suggestions of other projects to put into a stripboard layout, feel free to let me know

(ps - I’ve just tried to upload the mixer layout here, but it says new users are limited to 1 photo per post. I’ll upload it here as soon as I can)

I think it’s a very good idea, I built all my modules on stripboard, even some new (VCLFO, Mini ADSR), but I did not compose stripboard (no software and no experience with that), I do it as and when the schem, but it would have helped me if I had this before, so surely very useful for others who begin
thank you :slight_smile:

I will definitely be building the Dual VCA, just need one more 3360 and I’m on it! Thanks for sharing! :smiley:

I hope I’m not speaking out of turn, but I find it very frustrating that some people seem scared to post a new implementation of a good design in case they upset the person who published the original.

Good ideas are worth copying.

I second that wholeheartedly. If someone thinks he/she found a flaw in a design, this should not hold anyone back to publish a remedy. It happens too frequently that only after a while a flaw is discovered or a design is published before any rigorous testing has been done.

I am all with you here, especially with stripboard! Though, I find it a little bit difficult when people invested a lot of time in designing a circuit/module and are selling pcbs and then you take their design, just copy it and then give it away or sell it yourself. I mean, I am pretty much anti copyright (and anti-captialist btw xD) in general, but it still feels a bit… sour?.. I don’t now, it’s hard to draw a line here, and I am not good with words… just what I feel, feel free to argue :slight_smile:

What about simplifying the layout? Pin 3,5,10,12 of TL074 are connected to ground. Remove the track cuts between 3+12 // 5+10 to save some green wires.

Hmm, that color scheme is a bit unusual…

And I thought it was just me. Trying to follow that layout map would drive me insane.

What would you use? …

Black is circuit ground (0V), not “most negative voltage I have in my circuit”. That’s not negotiable :slight_smile:

Beyond that, conventions vary slightly, but a very common one (looking at lab supplies, etc) is blue for the negative version of red, and green for actual earth, as in mains ground.

Whatever colour comes to hand if the length is right.
Most of my solid core is salvage and is usually "sorted " into one large carrier bag looking like the spilled guts of an 80’s robot buddy. Never quite bored enough to sort it out.
Probably just end up with a King Rat!

Now of course in US 110V electrical wiring, black is hot, white is neutral, and ground is either green or bare.

Yikes! That’s a very frightening clash with electronics conventions.

Interesting metaphor.

Some form of this turns up in Pratchett. The Amazing Maurice, I think. And of course in what passes for real life.
