Simple LFO Kit
![](/l/uploads/medium/4a67133d905a866742b5ce877a2cad21.jpg)
A small kit is available for purchase! Check the “shop” page.
In the Kit, you will find the following:
Resistors, 16mm potentiometer, connectors, capacitors, IC and its socket.
Currently, no faceplate available. You want one? Tell me!
I made a double front panel for 2 LFO modules. It’s available for purchase. Contact me.
This is an outdated version, an update is available!
What shall we do with the Unused Op-Amp?
I was testing one of my projects and was annoyed by a lot of noise at the output on the last stage Op-Amp. What was wrong?

What’s on TV? “Everything you wanted to know about soldering and desoldering but were afraid to ask”
An excellent video on soldering techniques. SMD soldering is simple! Even if you don’t own a hot air station, the techniques demonstrated here are very helpful to anyone interested in SMD soldering.
Circuit simulator in JavaScript
Falstad’s Circuit Simulator applet has been recently translated to JavaScript. This port, even if a bit slower than its Java based big brother, will allow simple iframe inclusions on all web pages.
Here’s an example of this great tool:

What’s on TV? “Electrical Transformer Tutorial”
An other great Youtube video by Afrotechmods.
The basics of how transformers work, where to shop for step down mains transformers, and how to wire one up to mains voltages.

New modules coming, fresh panels from FPE
While I’m still designing my DS8 drum clone, I’m preparing some new modules. In fact, they are designed as build bricks for the drum module.
I made a simple square and triangle LFO, a simple AR Envelope Generator and a 3 way mono mixer.
In the meanwhile, I tried for the very first time the Front Panel Express service (Schaeffer AG actually here in Europe), and I just received my first panels yesterday.
I have to say 2 things: first, their service is not cheap at all. But, wow! I’m really happy with the result! What a nice and professional result! Check it out:

It’s absolutely brilliant! If it wasn’t the price, I would definitely recommend their service!
They are 2mm thick black anodised aluminium panels. Texts and drawings are raw cuts with no white infills. Still, the result is very good: it’s perfectly readable.
Edges can be a bit rough though. Anodised aluminium doesn’t catch finger prints. (PMA glass does it a lot!) At 2mm thick, the panels are really stiff. Surface is pretty hard to scratch.
All in all, I’m very pleased.
If everything goes nicely, I will build several of these and sell ’em as separate simple modules. Keep in touch!
Next to come are an impact gen (actually a clone of a 606 bass drum), and probably the noise generator.
