heinzboehmer's 2002 Topaz 6MT Coupe

[heinzboehmer]

Milestone!



And of course something had to break. Fortunately it was just the clock adjuster. Instead of doing the sensible thing and fixing the cluster, I decided to write a bit of code and have the car's time auto sync to GPS.

I've configured Gauge.S to send the GPS time out as part of its D/I Bus relay packet. On (electrical) cold start, the BlueBus will wait until it sees a valid time (in reality waiting for the GPS to lock), then set it. Works great!

Setting the timezone and DST is kinda clunky with the CD53, but it works just fine. If I'm bored one day, I might add latitude, longitude and date to the D/I Bus relay packet, then spend (probably an unnecessary amount of) time coming up with an algorithm that can efficiently do a lookup on a world timezone map and set everything automatically.

Repos (1, 2) updated with the config and code.

Slick!! I love it - that's a great QoL improvement!

It really is! Feels nice to never have to worry about setting the clock again.

... but how will you reset the trip?

Trip is push on the LH button, clock is turn on the RH button

[Obioban]

Ha. Damn it.

Shows how often I use the trip :P

Back in the day, I'm pretty sure my Intravee's set the clock based on GPS time.

Thanks for the link! Was gonna design my own, but glad I don't have to now.

Weirdly, only the "forward" adjustment broke. Turning the knob CCW and pushing it in still works. But yes, I need to actually fix this at some point, the auto time was just me being lazy. Writing some code on the couch was more appealing than taking the cluster apart at that moment for some reason.

Finally caught back up on this thread and holy moly it delivers. You all are amazing engineers and truly my people

But then you have you have a lookup to account for DST !

You can always make an assumption about the TZ given the currently set time, if one exists. This is how the BlueBus does it on cars with Nav, where the GPS date and time are broadcast.

If you own an iPhone, the (v1) BlueBus can sync time off that via AT command.

BUT If you really wanted to get frisky you could use BLE and an App to just grab that data off your phone instead of via the Gauge.S

Yeah, it gets complicated FAST, ha.

I saw that part in your code. Dug around (for an admittedly short amount of time) and wasn't able to query the set time over I Bus. It looks like only the Nav sends this data out?

Definitely the easier (and likely cleaner) route. I'm a terrible app developer though, so decided to stick to what I know instead of having the robots build me some slop app that only works half the time

Hello Heinzboehmer,

I was wondering if you are sharing this repair file for people to print themselves and use?

Quick side project.

A bit more involved than just gluing the piece on, but it results in a super solid mechanical interface.

Here's an impact driver hanging from the replacement tab. Note that there is no adhesive present here:



In hindsight, running the above test was kinda dumb. If it failed, I would have had to source another pillar cover. It survived though, so we're good

For the final install, I did add a bit of epoxy in between the replacement tab and the pillar cover, for max strength. Seems to have worked out great!
