Obioban's 2005 IR/IR Coupe

[Arclitgold]

Hey nice work! Glad the hole wasn’t cut for nothing!

[Obioban]

Well, did another boring project.... but also kind of a legit upgrade.

I did my CSL trunk 19 years ago (vorsteiner). Since then, I've had no trunk opening button on the lid.

I noticed the other day that xtrons sells a trunk opening button/camera unit. When I made the wiring harness for my car, I had already run an RCA cable to the trunk, in case I needed it in the future.

So, I 3D printed a cutting template, sacked up, and cut a rectangle in my trunk for the button...

... only to immediately realize that it actually wasn't going to fit. The button spring mechanism wanted to go up into a space that doesn't exist.



Said a bunch of bad words, then cut off the button mechanism so I could install it and have a camera, and not have a hole in my trunk.



But, then I thought about it some more, and decided I could probably fit a touch pad switch in there. So, ordered this:

And printed a little bracket in ASA to locate it and indent the rest, so I can easy feel it through the rubber cover



Installed:


And done, with rubber cover back on:



Feels wild to be able to open the trunk by button again, after 19 years of CSL trunk.

Annnnnnd now they're saying they can't do it in glass. Guess I'm stuck with film.

[Obioban]

Speaking of karter16 , also went a different way than him on the center mounting tab modification

[Obioban]

Karter said that the glass screen protector might be too thick and recommended this version - https://screenshield.com.au/products...LSXH4mF.WHCYV2

Yeah, it may not fit. Going to try it and find out— I want glass.

If it doesn't fit without modification, may also try printing some spacers and using longer screws before I give up on the glass idea.

I do already have some matte plastic film on hand, if I’m defeated.

This post is really as much as note for future me as it is for anyone else.

The Xtrons Screen without bezel measures 96.5mm by 228mm.

I ordered a matte tempered glass screen cover from here, which goes beyond the visible area of the xtrons screen (so the edges won't be visible with the bezel on) in 225mm x 94mm.

I think this should really up the feel of the thing. I can't stand glossy screen in cars, and glass feels better to the finger than plastic (and shouldn't ever get scratched).

Also printed out Bry5on's chrome free, more OE looking knobs.

Are you sure?

I feel like we need a video to be sure.

Will make a track video for an entire session, aimed at the AirPods case 🤣

Still should hold up to a full G force left turn, as the bottom of the case is still braced.

I just updated the ashtray with a bunch of improvements, so if anyone downloaded... download again.

Update is really just a sport for a finger so they can be grabbed. They were tricky to get out before.

lol, sure, but they're not really... designed to be customer facing. :P

I'm probably going to revise it to have a finger cutout to make removing the airpods easier.

Hole cutting template:
https://www.dropbox.com/scl/fi/pvmwg...tf5&st=hnam13v b&dl=0
This inserts into the induktiv phone cavity and gives you a template to dremel the hole for the magsafe puck.

Magsafe trim:
https://www.dropbox.com/scl/fi/8ouzo...cxas&st=u7eicf jw&dl=0
Goes around the magsafe puck to hide the edge of the cuts.

2: https://www.dropbox.com/scl/fi/y9anx...x66iokjl&st=77 bjjecr&dl=0
These support the MagSafe puck from below (epoxy in). I'm not sure if they'll directly apply to all Induktiv chargers, as mine looks like it had milling as part of production. I'd have to imagine that was because it was an early unit, and that wasn't the long term solution...

These use zip ties to make it so the plug can't vibrate apart behind the dash, without obstructing the charger's cooling

That's awesome! I've also been disappointed with the charging on the inductiv unit. Any chance you are willing to share the 3D print files for the different pieces you used?

Did some quality of life upgrades. I've had the Induktiv qi charger for a couple of years, and I like the concept but the actual charging execution sucks a bit. Decided to improve my general charging situation while I was at it.

Generally, I'm tried chargers that are running near capacity overheating in use and stopping working for periods/forever. Sooo...

Bought this 167W GaN charger and connected it behind the dash:

https://www.amazon.com/dp/B0CZ7BL16W

Replaced the cigarette lighter tube with this, and ran it to the 100W port on the charger:

https://www.amazon.com/dp/B0DSCVHQ14?th=1

cut out the qi (1) charger on my induktiv charger and replaced it with a 2nd gen MagSafe puck (and printed it a little trip piece to hide the cut):

https://www.amazon.com/dp/B0DGJ4QQ5W?th=1

3D printed a new ash tray and installed a (USB A) Apple watch/airpods magsafe puck in that:

https://www.amazon.com/%F0%9D%9F%90%F0%9D%9F%8E%F0%9D%9F%90%F0%9D%9F%90-%F0%9D%90%94%F0%9D%90%A9%F0%9D%90%A0%F0%9D%90%AB%F0%9D%90%9A%F0%9D%90%9D%F0%9D%90%9E%F0%9D%90%9D-Magnetic-Charging-Compatible/dp/B0B2R7G9ML?crid=3CDO32UM41PNW&dib=eyJ2IjoiMSJ9.V4_lM2euDGiFr-_WE1ZJVCVGUlUa2hyHyjUAbjal3QyT6rK1qvknKuAB513TKnoamz9UI7U53ZN3jpTcpR8UyNQqjh6HgMcap5e1DoSVrSEJF2sbI3R7noBR-JOSyGV-sK3_VrNit4h3dRb3lK6LJ0948jKi3FyldYv5nfp92XxI-7Ys6J-CPzCpvgOmDgZhVltOiGmahE1Xw7Db4NtVrgwxg8BfZAp07CXS04QWogY.-XLLrUamI7IvNthSA0R6Bk_orEiBp5bNWF0YJzb3P1Q&dib_tag=se&keywords=apple%2Bwatch%2Bcharger&qid=1776859894&sprefix=apple%2Bwatch%2Bcharger%2Caps%2C148&sr=8-4&th=1

Result:





I'm pretty pleased with the result. Everything is close at hand, but disappears when the armrest is down and ash tray is closed.

The iPhone MagSafe plug is rated for 45w and will max out at 30W pulled, so should have plenty of thermal head room.
The Apple Watch charger plug is rated for 22W, and pulls 5W at max, so should have even more thermal headroom.
And, the bonus 100W USB C port might be occasionally useful, and it's pretty unlikely I'll ever be pulling 100W out of it.

Thats awesome. I went with the rennline mount and then added the magsafe charger to that.

The USB extension 12v plug replacement feels like it was made for purpose-- press fit in, and it's secure, with no modification required.
