Percussa SSP Layout #3 and Software GUI update #1

Percussa SSP GUI Layout #1 Kickstarter update

Published on Oct 8, 2017

Update: video above added.

"A short video of the first GUI code for the Percussa SSP. It shows the parameter values in large font when starting to turn an encoder. When you no longer turn the encoders, after about 2 seconds the parameter values become smaller again. We will continue working on the GUI in the next weeks and we’ll be sharing more updates along the way."


via the Percussa Kickstarter site:

"Last week I finished routing the first revision of the PCB layout. After that I built a list of all the remaining things I need to check in the design, which includes (non exhaustive list) checking trace lengths, spacing, width, checking footprints, checking which traces are potentially too close together, checking all the mechanical aspects of the design, …

This reviewing phase is just as important as doing the layout itself, because it’s easy to overlook a small mistake, which could imply the prototypes we’re manufacturing have to be redone.

To check everything mechanically I export my PCB layout into my 3D solid modeling software, to verify the placement of all the components, how everything is mounted together, double checking whether there is enough space between the buttons and encoders, enough space in between the front panel and the PCB, how the display will be mounted onto the front panel, etc. I think I have another 1-2 weeks of reviewing to do before we’re ready to send the PCB Layout out for manufacturing. As you may have noticed, we are currently ahead of schedule with our work.

Besides that, Celine has been working on the GUI code for the SSP and would like to share her progress:

To build the GUI for the SSP on top of our existing code base quite a bit of architectural work is necessary. The software currently runs on the functional prototype we’re using for our demos (the Percussa Engine). I’ve decided to start with this while Bert is focusing on the hardware design, as it’s closely related to his work. Below you can see a short video of the first GUI code I’ve worked on, to support showing the parameter values in large font when starting to turn an encoder. When you no longer turn the encoders, after about 2 seconds the parameter values become smaller again. I will continue working on the GUI in the next weeks and we’ll be sharing more updates along the way."
