Thank you!
How did you?ā¦. I didnāt think I entered that anywhere.
Because itās mine too!!! Everyone who shares a both day just knows. Thatās what all these dang chips are for. Tracking each other - didnāt you get the buzz for mine??? you might wanna checkā¦

Any rough guesses at wattage I would need for a trickle charger to make up for a XACv2?
Interior of glass will likely take half off the top,
Then you have a 24 draw, and maybe 8 hours of available sunlight
Itās what? 200 milliamps? Call it 5 amps/day. 5 amps * 12v = 60 watts/day. 60/8 hours = 7.5 watts/hour. Iād oversize it to a 20 watt panel because youāre never really gonna get peak power.
I thought 100ma
Edit
Meh, solar is not a prospect I like,
Seems like a bandaid fix, why add a system to charge the battery back upā¦ instead of just limiting its depletion
I need to figure out a way to turn it on and off from outside the carā¦ thereās a small trim window forward of my side mirror, I could maybe drill a hole, and put a small momentary switch perhaps

Oh, yeah. My bad. Well, another thing to consider is that your car is already bleeding power on its ownā¦ So youāre solving more than one problem. If youāre the sort of person that plans on leaving your car unattended for a week or more, itās a great solution. If notā¦ Well, you might not need to worry about the power loss after all.
Thatās fair,
Just seems like the ability to turn the reader on for 60 second cycle when you need it would be a more elegant concept
Iāve had previous cars that if you pulled the handle on a locked door, the interior would illuminate for 1-3 minutesā¦ that would be perfect, but my fiesta has cut that corner sadly
Totally. That was my plan with a PIR sensor but then you have to seal the holeā¦ Think about car washes. They tend to use pressure washers. Nothing you seal it with will hold it up to thousands of PSI. That was the big nail in the coffin for me. (Read: Iām too lazy to hand wash my car).
The door handle thing is an interesting ideaā¦ You could potentially use a momentary switch in thereā¦ But youād need to use a delay off timer, I think, because holding the handle while trying to use the XAC will prevent the lock from actuating.
has anyone actually tried a PIR sensor positioned directly up to the back of the glass in a car? itās not like it has to work at 15 feet or anythingā¦ just a few cm is all that is really necessary.
YouTube test video. YMMV.
Edit: I would happily do a proper test but I wonāt be home for a couple months.
Edit 2: I suppose it would work if you rested your hand on the window long enough because it could heat it up enough to be detected.
The xAC V2= 60mA Idle 100mA Operating
Even better
The problem here is that the āscienceā being done in the video is nothing like what is being proposedā¦ āglassā does not reflect IRā¦ only certain types do. The āglassā used was super thick and obviously not UV filter car glass (which I think passes IR just fine to help avoid turning the car into a solar oven). The sensor is fully encased in its own plastic casing with its own index of refraction etc. and Iām not proposing such a module simply be placed inside the carā¦ what Iām saying is you silicone glue the actual sensor right up to the back of the glass;
That thingā¦ put that right up against the back of the glass and test for motion detection at 2cm - 10cm away with a human handā¦ my bet is it should workā¦ but we wonāt know until someone tests.

100% agree with more testing testing. My intention with the link wasnāt āthis wonāt work.ā It just seems to jive with IR not wanting to pass through insulatorsālike glass. Sorry for the confusion.
Edit : a contactless thermometer might be a good way to test this without assembling something.

Totally understand. I can get spicy sometimes when it comes to multitaskingā¦
