About

Keep It Simple, Stupid!

I've been a musician for a while now - up until quite recently my weapon of choice was a bass guitar, but having fallen down the rabbit hole that is modular synthesis I have a new way to make noise ...

I started out the usual way: buy a rack and a bunch of modules (ADSR, VCA, VCO, that kind of thing) and start making noises. Then I discovered the DIY scene and it all snowballed from there - sequencers, filters, logic modules ... four racks full of noisemakers later and I'm still not done.

My modules are Eurorack-friendly by default (3U high) - although I have 'proper' PCBs made for them, all of the soldering and testing is done by hand ... that includes all the surface-mount stuff in the newer modules.

I'm a big believer in the KISS principle - Keep It Simple, Stupid! If you want all-singing, all-dancing multifunction modules then this really isn't the place for you - similarly, if you're after ultra high fidelity then you may well be in the wrong place; I like my sounds to be lo-fi, dirty and more than a little bit strange.

Finally, yes, my modules are pretty cheap - the reasons for this are simple: I sell this stuff to supplement my existing income and to fund a hobby I enjoy - board runs are kept small (usually 10 at most) and I try to keep costs down where practical; this was one of the drivers behind switching to surface mount - that, and I enjoy the challenge of soldering SMD.

For the really curious, despite working as a software developer I do have a PhD in theoretical physics, specifically the numerical simulation of explosions. It isn't nearly as interesting as you might imagine :-p

Now, go forth and make an unholy racket!

Frequently asked questions

Custom and personalised orders

Quite a lot of stuff is made to order, and as such turnaround time will vary.

As a rule of thumb:

- If I have an item in stock and already built: it'll be dispatched within a couple of days. Items are generally shipped out on Wednesdays and Saturdays.

- If I have the bits in stock but not yet built: figure on a day or so for build time and then dispatch as above.

Where a module is listed as in stock I endeavour to keep at least one fully assembled unit handy for fast(er) dispatch.

Whilst I would love to be able to do large runs to order, the sad fact is that I lack both the time and resources to do so. However, if you're after multiple PCBs then maybe we can talk ...

Regarding perspex panels

Eagle-eyed viewers will have noted that the modules now come with 3mm perspex panels - these are far nicer (IMO) than the old wooden panels were.

The panels are laser-cut, 3mm clear acrylic with laser engraving - the base colour of the material is a translucent grey. The rear side of the panels is coated with dark enamel paint to highlight the engraving. For modules with LEDs, this gives a nice, diffuse effect.

It goes without saying that you should keep them away from solvents (isopropyl alcohol, acetone etc.) - you can clean the panels with a damp (not soaking wet!) soapy cloth.

By default, I will supply M3x10 screws for mounting the panel - if you use M2.5 or something else you'll need to source your own mounting hardware.

Do you offer bare PCBs?

Yes, for the through-hole module kits.

If you want the bare PCB for another module then submit a custom order and we'll sort something out.

Regarding shipping ...

For non-UK orders I use Royal Mail "International Tracked and Signed" - you'll receive a tracking number with your dispatch email. For countries where this service isn't available (eg. Australia) I will use "International Signed For" instead - in most cases, you'll get your swag within 5-7 working days. You can get full tracking info via the Royal Mail's website.

UK orders will be sent First Class Signed For - Special Delivery is available on request (at additional cost) and will be used for particularly valuable shipments.

Customs declarations will *always* show the true value of the contents (ie. what you paid me, less shipping)

What mounting hardware is provided?

All modules, including tiles, are provided with an appropriate number of M3x10 machine screws for mounting in a case - these should be long enough to accomodate the increased thickness of the panels in 99% of cases - much will depend on the rails you use as well.

However, you should be prepared to use shorter or longer screws depending on your exact setup. Most people have these lying around and they're cheap to buy from electronics supply houses (the screws I supply cost about £2 per 100)

If you're one of the outliers who is using M2.5 or 4-40 screws then, unfortunately, you'll need to provide your own mounting hardware. If the supplied screws don't fit, then it's a good chance that you're one of these people.

I want to make my own panels - can you provide the files for that?

I certainly can - just ask.

I can supply files suitable for use with Schaeffer's Front Panel Designer software and/or AutoCAD DXF files. SVG files are also available on request.

If you just want to cut your own panels out of a different material then DXF is probably what you want - just send it to someone with a laser cutter and you're good. If you wish to customise the panel then the FPD files will be your best bet.

Unfortunately, I am not able to supply modules without panels.

Can you supply a power supply for the 'desktop' modules?

Unfortunately, no.

Because different countries have different mains plug standards it isn't viable for me to keep the different types in stock. If you need to purchase one then I'm quite happy to point you in the right direction.

What sort of power supply should I use for 'desktop' modules?

A standard 'wall-wart' will do, as long as it has a centre-positive connector - the power jacks I use have a barrel diameter of 5.5mm and a pin diameter of 2.1mm, which is about as close to a standard as you can get for such things. Note that guitar pedals often use centre-negative supplies - these will not work.

Most of the desktop modules have a 9V regulator on board, meaning your power supply should supply at least 12V DC in order for the regulator, and hence the module, to work.

In terms of current, a 100mA supply should be more than adequate - most wall-warts that people have lying around will be rated at a couple of hundred milliamps.

Can the desktop modules run off batteries?

There's no technical reason why not, providing you supply at least 12V to the module or are prepared to replace the on-board voltage regulator.

If you're DIYing, you could always use a 7805 voltage regulator and run things off a 9V PP3 battery. Your mileage will vary (considerably!) as regards battery life.
