I finally got my new test HW in and partly assembled.



Everything is working great. I have a few new parts on order and am building the adapter harness to plug it in my car for final testing. I made some changes on this rev to better support the development of the Bluetooth interface since many have commented that they would desire that feature (the BT module can now be updated and interfaces with directly over the USB!). Once I am satisfied that everything is working well and stable, I can pursue getting fully assembled boards ordered! Exciting

I plan on setting up a wiki page in the Gihub with information on how to email me for an assembled board. It seems like the best way to organize this kind of request.

We're getting close to v1.0.

I think this is an awesome project and would be interested in a board in the distant future but I have WAY too many other home projects to pursue at the moment

Things are progressing. I decided to make a change to the power supply design by adding a buck converter. The linear regulators were getting a bit too warm for my liking dropping the 14.5V down to 5V and 3.3V that the system uses. I figured that since this project could find its way into a car that bakes in the sun, I needed to minimize the heat generation from the parts that get warm as much heat as possible. The change should efficiently lower the 14.5V to ~6V and the linear regulators will condition the power down from there. Thermal tests resulted in them running about 5x cooler at the cost of only a few extra $$ in parts. Well worth it in my book from a reliability point of view! I have the parts on order to test this change and have already rolled it into the design:


I think this is the last thing that I will need to test before releasing V1.0!

Badass!! I can only assume you do this kind of thing for a living. I think I need to start looking at sourcing the A/C knobs and parts soon.

I have an extra set! I bought a non Nismo one, didnít realize the 2016 Nismo had darker knobs. Got the cubby too!

Its funny, I am currently working from home and my wife says she can never tell if I'm working on work stuff or personal projects because it's mostly the same activities.

I also just got a confirmation that the test PCB's for the Buck converter will be delivered Monday, so I should have some built for testing next weekend.

I'd buy one too, but bluetooth is a must so that USB port is open for charging

I am putting a lot of focus on BT at the moment to make sure that works as needed. I have run several tests that show robust data connectivity in the car environment. I also chatted with the developer of the Android app and he is interested in working with me in adding BT as a communication option. This once "optional" and "development needed" interface is getting more and more attention. I suspect that the HW will be ready soon with the updated Android app soon to follow.
