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.
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.
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.
The code for Dotty is beginning to take form. There is still a lot of work to do. The PCB has some errors that need to be solved. But that didn’t keep me from starting on the code with the first prototype. I started documenting a few.
Well this week the Dotty prototype boards where in the mailbox. I was quite happy to see the boards, at first glance it all look fine. But will the boards fit together, did I make any mistakes. Let’s start soldering.
I’m waiting for the Dotty boards to arrive. Meanwhile I ordered some other boards and these came in quite fast. Haraldswerk.de has some great modules online. You can download gerbers and information on his site.
After building the NanoGrids I was still looking for a nice drum trigger sequencer. I want to have a bit more control over the drum’s then the Grids is giving. And stuck in my room with Covid I started designing something. There are a few modules out there that you can buy/build. Some really nice one’s also.
Lately I’ve been get more questions about this module. The github repro has some basic information but not the whole story. Here is the background on the module, some insights and some help to make you build one yourself.
