The fields are identified by a numeric code known as the "OBIS" code. The issue in parsing this is that there can be multiple values in parentheses added after every OBIS area. Then there's values added in parenthesis after it. This all glued together signifies that the DSMR module will get the info from the P1 port and then sent it out over WiFi to my MQTT server with a separate matter for every discipline. Adding a community port for the audio mixer would imply it needs more swap ports within the field and since the community swap ports are on the outside it would wish an ugly cable popping out to the front of the field to attach it up. The need for instances has annoyed me several times already when designing PCBs. If I'm lucky I don't need many exterior holes to fit buttons or connectors and if I'm actually fortunate the mounting holes for the board are even in smart places.

Initially my code was running on an off-the-shelf Teensy 4.1 and utilizing only the digital enter and output I could use immediately with an exterior ADC/DAC. The define of the case drawn using the graphic components in KiCad. I did a few iterations on the footprint library and did a collection of check prints of the case to ensure every little thing is right and that i can fortunately report that all the pieces simply matches up completely. This turns out to have a few apparent flaws, for example the ESP32 module that I've hanging over the edge of the PCB. I have ordered the Teensy audio shield which offers an unbalanced stereo enter and output but while that's delivery via Europe I wish to get some more growth in. This creates a fundamental audio mixer with 6 inputs and 4 outputs. KiCad PCB file and the field(wall, bottom, height) module creates the actual fundamental case. A case outline from a user layer.

I picked the User.6 layer because the case define layer since it has a neat blue coloration in this KiCad theme. Information about connectors to make holes in the case and to have placeholders in the ultimate OpenSCAD file for simpler modifications. I guess the UX for designing things is just quite a bit easier when you only have 2 dimensions to worry about. There's a whole lot of neat issues that could be added to this. Since writing the weblog post about the main points on how TurboCase works I've added assist for TurboCase-particular footprints. Since writing my earlier publish concerning the digital audio mixing I've made some important progress. Local printed press taught me to pay attention to details, whereas Srajan’s witty storytelling proved me that professional audio publications may be correctly informational, utmost interesting and entertaining at the same time. So after I acquired USB alerts working as a proof of idea I wished to get some more audio channels to make it an truly useful audio mixer. Luckily I acquired to make use of one of many features I gained by switching to PlatformIO: Unit testing.

The system may be prolonged by producing a footprint library particularly for turbocase to signify the place to add particular options to the case. I now have a worldwide KiCad library that holds footprints that are designed to go on the User.6 layer to add prefab options to the final OpenSCAD file like screw holes in the case and the opening for by USB-C connectors. The RJ12 connectors already cross the border of the case in KiCad so there will probably be holes generated for them routinely in the case based mostly on the connector outline on the fabrication layer. After enjoying making a PCB in KiCad the annoying for me is all the time getting a case designed to suit the board. The extra annoying part of the whole process was dealing with the software program. The whole thing is little endian. I decided to export the instances as OpenSCAD information. This is mostly as a result of these are simple text files I can generate and that i already have some experience with OpenSCAD design. The options are either grabbing an off the shelf challenge box which is normally costly and never suits exactly with the design or simply 3D printing a case which includes me angrily staring at CAD software program to figure out how you can make issues match and match up to my PCB.
