Digging thru your code is going to make this process so much easier, and for that I am very appreciative.

Well, I've developed a custom power/data board for the M5Stack platform. This is the board that was developed for the OnSpeed energy/aoa display, and it works with all of the custom bezels/mounts that Rob Prior developed. I will be developing a number of new boards like this in the future, for various applications (engine sensors, CAN bus, trim motor control, etc.) All will use the M5Stack display.



I'm still organizing getting these boards into inventory at OnSpeed. My first batch is 18 boards.

I also have a link to the Shapeways 3D print library for Rob's stuff. Email me or Rob FMI.

24 VDC???
 
Hey Vern - Any chance your power supply board is 24VDC compatible for us industrial controls types? If you are looking for thoughts on future boards... How about a POE version? Let me know if I am getting carried away ;)

Cheers, Sean

Right now, I am only focusing on aircraft/automotive/marine at 12V. It will easily withstand much higher voltage pulses, but not continuously. M5Stack has a PLC base for 24V, but it isn't protected. It also has a bizarre form of RS485 that is not 485, Not CAN, but somewhwere in between (uncanny). Most of the components on my pcb are for protection. It cost more for me to make this board than the M5Stack cost.

I'm avoiding mission creap here because I don't have enough real time for all of my projects as it is (arduino graphics libraries, OnSpeed design work, hardware design, fixing my boat, marketing the blueheronaeropark.com development, building another airplane and working on a military helicopter simulator program). They call it 'retirement'.

Retirement???
 
It only means you don't have too work! I hope to join you some day.:)

Retirement means you don?t have to drive to work but sometimes I think I should go get a job so I can rest !!!

Another teaser of the OnSpeed energy display:

I just finished building my OnSpeed harness and that rolled up wire close to the DB15 connector is wired for "future use" AKA your display when ready. Zoom into the picture and you'll see a tape that says Vern's Display !!




I connected it and no smoke, that's always good, and WiFi connects and communicates quickly !

Sorry if I didn't properly response to this suggestion previously. If you go all the way back in this thread, you will see the original Arduino (ATMega or Teensy) design that I have release as open source. It was tuned for aircraft applications and I fly behind one programmed as an auto-trim and flaps controller. It fits into a standard off-the-shelf Hammond case. It uses all through-hole devices so it can easily be built or modified.

Then I developed a surface mount version and switched to the awesome ESP-32 controller. Again it fits into a standard Hammond case.

Finally, I used the off-the-shelf M5Stack display module, which contains the ESP-32, common interfaces, an optional IMU and a bright 320x240 TFT Color display in a compact package.... with a retail price less than my cost to build my other boards. My focus now is to develop custom 'shields' (such as the power/data board).

For those monitoring this thread, the next shield will be for 24 volt applications. Design is done, waiting to gauge demand.

We've finalized the M5Stack panel mounts, and in my next aircraft I will be mounting six or eight of them on the panel as programmable instruments and copilot displays running my graphical widgets library.

In the meantime, I will be installing my OnSpeed brain box in my Harmon Rocket and tweaking my back-seat EFIS display, building my RV-15 clone, and getting ready to move to my new hangar at www.blueheronaeropark.com.

I'm always looking for new applications to code or for hardware development, so I welcome suggestions. I am doing this entirely for non-commercial (translation: I do whatever I want, whenever I have time) purposes to further the advancement of our industry. Everything will be released as open source, and posted at www.huvver.tech, but only after complete flight testing.

Finally, I want to give a shout-out to Rob Prior for the 3d printed parts and has contributed his time and expenses to this project. As we electrical folks say, “the electrical design is easy, it's the mechanical stuff that's hard’”. Funny, though I've never heard the opposite said by an ME (mechanical engineer).

Cheers

The ME part is mystical sorcery to me...

Funny, that's how I feel about the EE side... :)

Thanks for the kind words, Vern! I guess whether it's EE or ME, when you've spent 25 years (or more) doing it, it becomes second nature.
