Infotainment System for Porsche Car [from CAD, prototyping to finish]

MOTY ; Most Obsolete Talented Yawny!

To bore you all more... here goes a Quick Update and more funny pics

Was struggling with the little four USB dip thingies I previously sourced online (seen in previous screen grabs; little independent pcb holding a single usb port). Wiggly stuff, and it needed a pretty complex system just to hold that stack-of-stuff together. Too many screws also and sure it would have needed bubble gum to patch things up loll

So I just tossed away that old stuff and went custom, again. Why making a fuss ab it and where does this leaves us?! Nowhere, just a week behind/late as we now need to wait for the parts to show up and test out okay :/

All better stuff tough… TE Connectivity /AMP only, a whooping $0.8cents/connectorX4 onto a $0.25 PCB. We’re so awll ruined

I’ll update nx week when things are working again.


^ Talking about this little 4 ports connector pack. Present itself on the ‘back’ panel (not the front, no worries loll)


^ Goes here, there, somewhere in that lower back corner.




^ As shown above, even the most advanced circuit board known to human (and other races) can take up to 5hrs to measure and put together in a CAD assembly. Thankfully, FREE software like Circuit Maker does it so well. So easy you could ask your sister to do those PCB for you



^ Once you've toasted this in C.Maker, aligned everything and made the current traces thick enough to cope with 500ma, you then shoot this over a PCB Printing Co in Gerber format and they'll do the rest for you. Example of this same PCB loaded onto OSH Park's backend.

And that is how its done, basically! Lucky for me, the pcb printing companies here does it in 24hrs (+1 day shipping). Hehhehheh

And $4 dollars later LOL (all very important Quick Updates fellas)

Yayyy we have USB x4!!!

Hrrr.. that was hard for some freakin weird reason, for me anyway. Partly because I wasted so many hours trying to fit in those previous pcb/usb parts I got at a dollar each. Glad those are in my Royal Rubbish Bin now. See... trying to cut corners to get things done quick and dirty just never works :/ Oh well, at least I've tried lolll

Anyway, happy with below CAD fitment and look & feel. Solid kit; TE Conn/genuine connectors, all fun stuff!

Thank you very much for listening(reading), almost feeling better now

Amazing stuff Fred! First thing I look at when I open my computer in the morning!

Oh man, that is so cool to hear. I'll try my best to detail the steps the best I can and update as often as I can. Unfortunately I have to leave a lot of stuff out as it would just bury the whole "car related" thing under a ton of technical rumble. I'd get bored myself loll I'll try my best to entertain more! Thanks for the encouragement bud

Cheques are for important stuff my friend! Trying to built this kit in a way that we can pay them off with our spare change Already reached the $250 mark. Goes fast :/ (sukx, this world needs rebooting man)

The whole system is rated at 5AMP. Runs both 12VDC and 5VDC independently and managed/filtered by a uninterrupted power supply (UPS) over a MODBUS logic. (Spanish for good stuff)

5AMP = 0.4amp for the whole system itself. Very energy/efficient. Intel Corp… pffff. That means it leaves you with little over 4 amps for your USB hub. Unseen yet in the screen grabs is a Hub Controller (pic below) which is rated at 1 amp per channel (has 4Ch).

Unless your GF decide to retrofit her hair dryer to USB one day or you plan on powering your HID lighting off the back of a Car PC, then we need to talk man loll As of most of today’s commercially available USB devices, we should have more than enough overhead with that 4amp Man that’s a lots of webcams lollll

USB 2.0 of course! Compatible to literally everything. If really you need the 3.0 digital signals (or xfer rate), something tells me this is something that normally doesn’t happen in a Car. Regardless, the mainboard already has 1 (one) built-in 3.0 port, few ways for you to access it if really (really really) you need that

Hope that answers your Qs bud. Feel free to ask any other questions (other than USB related LOLLL… man almost hate the thing now)




^ Spanish for S.M.A.R.T lolll

*Quick Update*

The Great (great) f n USB Hub! Completed, routed and space reservation allocated.

/End of update. Don't want to have to do this ever again lol






PS: just joking... I actually love this thing. Micro stuff... about the size of your thumb.
