Dotty: 1.4 Overview, Features, BOM

With version 1.4 I have a working prototype with a panel. These make mounting it in a case possible. There are still some minor issues I want to fix before releasing it to the public. I build Dotty so I know what to expect. But I would be nice to have some feedback.

This topic is mainly for those whom received or are going to receive a 1.4 prototype version. I hope It helps with the build and explain some of the features. If you haven’t received a Dotty but curious on what it can do, keep on reading.

Dotty: Building v0.04 are we done ?

This weekend finally the new backboard and panel arrived. Been waiting for these whole week. Could not wait to start building it in the hope I finalized all mistakes. I didn’t make a new front pcb cause I think everything is correct on that one.

(I can reveal that Dotty is working and in a phase where I’m looking for Beta Testers. Got 3 PCB’s left so if you are interested, contact me.)

Dotty: A new back pcb and first panel

Yesterday I finished the designing of the first panel. Today it got excepted by JLC. So I’m hoping to have new back pcb’s and panel in the next two weeks. The panels are the first version for dotty and I did some moving of headers. So I hope all will line up and it will fit. But will have to see when the pcb’s arrive

Bigger picture after the read more

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.

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.

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.
