Range-switchable clock module that varies from ~1 Hz to ~12 Hz (actually down to 1/4 Hz thanks to the integral clock divider)
It has 4 outs of the main clock, plus 1 each of 1/2 and 1/4 clock division, designed to make it easy to do simple beats (or anything else requiring clock division) without needing a separate clock divider.
The pushbutton to change the range has a blinkenlight inside it.
This is a KIT which includes everything necessary to build one of these. Note that this is nearly entirely surface mount. I used to be scared of it but nowadays I prefer it to through-hole because you don’t wind up with all those little metal legs that fall on the floor & then get tracked into a room with carpeting where they stick up and stab you in the foot.
The six things you need for successful surface mount soldering at the scale of my kits (0805 size components):
- A decent soldering station
- A lighted magnifier
- Decent tweezers
- A flux pen
- .020″ solder
- If your iron is a Weller, an ETA tip, or the equivalent for your iron
A lot of my percussion modules are expecting well-formed triggers, but clocks and other things typically put out gates. This is a dual gate-to-trigger conditioner — it will narrow just about any gate down to proper trigger width, but its output is also fully adjustable from 0ms up to the full width of the original gate. So you can use it if, for example, you’re using a clock divider that puts out double-length gates that you want to shape back down to the same width as the rest of the gates you’re using. Or anything else along those lines.
The trigger/gate width is fully CV controllable across the same range that the knob gives you.
The input of the top half is normalled to the input of the bottom half, in case you want 2 different lengths from the same gate input.

A simple stereo mixer — it has 1 plain-mono input, a second mono input that becomes a hard-panned left-channel when the third input, a dedicated right channel, is patched into. No pan pots, sorry, it’s 2HP. I actually designed it to go with a combination 4-way low-pass gate and stereo panning mixer that I haven’t gotten around to uploading here yet.
It has a reasonably decent headphone amplifier IC as its output stage, set to provide enough gain to drive my Sennheisers.

Seems like everyone has to design one of these sooner or later.
The jumper-able 5v/ground on one side is borrowed directly from Transient Modules.
My biggest peeve with Eurorack breadboarding is jacks — with pots, the Song Huei tall trimmers are easy to come by, cheap, and their legs fit breadboard holes pretty well. But jacks are a pain, so I went ahead & put three on here. The cutout on the board is to give you access to the rows where the jacks’ tip contacts come out. Sleeve & switch are both tied to ground for simplicity’s sake.
Updated VGA adapter designed for mounting in a 3U (e.g. Eurorack) enclosure. Also features buffered individual outputs for RGB coming in from your VGA input, for patching/processing in the ec500.
