Dotty: New panels came in

The new panels for Dotty came in the mail today. I just could not wait to fit them on the module. It seems a very good fit just a tent of milometers off. The buttons jacks and led matrix fits a lot better this time. This was a small run of five panels. Beta testers will receive a new one in the mail.

Now it’s back to testing the code and the module. My number 5 and 6 buttons don’t seem to work anymore so lets see what causing that.

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.

Dotty: Progress on proto v2

Last weekend I have been playing with Dotty. Did a one hour session for friends and Dotty came thru. I didn’t even finished all the soldering. Left off the last three buttons, might be these will be lock version where all other buttons are non locked. Still thinking about that and the function I want to code for Dotty. Button caps didn’t arrive before the weekend, but I had to play with Dotty. Dotty does have a few bugs but certainly playable.

Dotty: Still working on it, prototype 2 on it’s way

I have been working with my first prototype of Dotty. Learned a lot and this weekend ordered new pcb boards. I dropped the TL074 from the design. These where there to drive led’s on output triggers and possibility to add some extra punch to the triggers.

The new prototype made with 2 pcb’s, a controll and a brains. I made the controls a little bit bigger for the buttoncaps to fit. I’m planning on using some big cap, the space between the buttons on prototype one wasn’t large enough. Let’s hope these new boards didn’t introduce new errors. Will have to wait and see.

Meanwhile the code is coming along, still a lot of work to do.
