Dotty: Prototype 3 it’s become a trigger sequencer

This weekend the boards version 3 came in the mail. I did some work on the clock input and added a clock output. The output still has to be written in code but the pcb now supports this. The boards only had two minor mistake so a four revision is probably needed, but it’s a full working sequencer now and it’s starting to look like a finalized product.

Building: Haraldswerks Buffered Multiple

This weekend I build some Buffered Multiples. The designs where made by Haraldswerks and the panel Gerbers by me as you could have read before. These little modules are really nice. Not just to build but also there function. Haven’t played a lot with them yet but running multiple oscillators from this module was quite fun this weekend. And building it only took about 45 minutes.

Dotty update…3 or 4 or…

Well I have been doing some work on Dotty the last few days. Fixed a few bug a found some new ones. Fixed those to and now I have a beta version of a working Trigger Sequencer.

It takes a internal or external clock. This part had a bug so I have to breadboard/redesign it. Volume drops don’t appear any more. Most function are written in code, but not all. Still want to make a menu for clock settings and general settings. So still a lot of coding to do and a little PCB redesign but I’m getting there.

Making panels in Kicad from DXF

Some people seem to have some difficulty making panels in Kicad. This can be a art on it’s own. I’m just starting to make panel in Kicad, so I don’t know it all but here are my tricks.

I came to this by the Haraldwerks designs. These where made with Front panel express, great tool for designing panels. But the price of these panels where a bit to much for me so I went the cheap route and made them from PCB’s

Building: Haraldswerk.de Quad LFO and Panels

The last parts came in and the panel I made from the FPD file Harald was kindly enough to put in the documentation zip. So the LFO is finished and working. I have to say this was a very nice build to do. Minor smd part (only a few caps) and good documentation. If you done a bit of soldering before but not a real pro give these a go.
