... nothing else (except Reverend Sam who didn't opt for the ELM327),
unless a software update comes out, you'll need a micro-USB cable to a computer.
Shipping I think will be late September
Every single unit will be tested before shipping out, so not all will be shipped at the same time.
I'll follow the list order from 1 to 14.

Thanks Bob. I'll take the standard, tracked shipping, same as MarkyUK. Looking forward to this! I already PM'd you my PP address as you know - just tell me when you want payment and I will transfer the funds.

I saw your PM, but since I get those a lot these days I don't answer all of them.

1) A working lighter socket*
* Ask as my lighter fuse kept blowing when used for phone charging...so will have to get that sorted prior to delivery.
Forgot to reply about the working lighter socket, yes it will have to work.
Unless you go with a hard-wiring solution
As I have to, since I already have something else in place of the socket.
And then a 12 to 5V converter is needed.
P.s. I checked my spreadsheet, it has 1048576 rows, of which 15 are occupied.
I assume this gadget will work seamlessly without the need to turn it on or connect it via bluetooth every time one starts the car. I also assume the user can select what to monitor for the upper and lower gauge (dependent on what is available for the year). I would prefer to have volts and coolant to check. Although I would like to be able to switch to gear box which is available for 2014. I currently use the torque app connected to an ELM327 and it's a PITA. I'd rather pay a bit extra for quality parts and a factory look so there is no messing around. This is a a very useful and clever gadget. Kudos for the design and location selection. We're all going to be rocking a Cabrio Bob gadget soon in our Jag's soon.
An update,
Today the "cheap" ELM327 was delivered. I tested this one with the ESP32, and it is working OK.
However, this one doesn't seem to go to "sleep" if no activity takes place, so I'll opt for the more expensive one
which is confirmed to go to sleep after 30 minutes, saving our car battery.
I found out that the ESP32 doesn't want to connect to another ELM327 if connected before to a different one,
more to be read about that here (post #19). Once I have done this ESP32 "reset", I was able to connect to the ELM327
using it's advertising name or the MAC address. Using the name is preferred,
since this enables me to write universal firmware (*4, one for each unit combination).
For this I have to make sure every ELM327 I order has the same advertising name. (for a Vgate iCar Pro 4.0 this is "Android-Vlink").
There are still some parts to be delivered from China, one of them seems to be stuck at customs for a week already
Updated list, see below.
I removed Reverend Sam, he didn't respond here, and also not to a private message.
On Thursday August 27 at 08:00 AM CEST I will close the possibility to sign up, and start ordering the amounts of needed ELM327 and 3D prints.
The sign up also closes when the amount of 14 people is reached.
oops! OK I changed that.
btw, if it is delivered with the wrong units, it can be changed easily afterwards.
I received a private question:
Just one double check, this will work on a 2011 right? I see that you have a 2007, and I don't know if any of the back end coding changed.
The device will support the following OBD protocols:
SAE_J1850_PWM_41_KBAUD
SAE_J1850_PWM_10_KBAUD
ISO_9141_5_BAUD_INIT
ISO_14230_5_BAUD_INIT
ISO_14230_FAST_INIT
ISO_15765_11_BIT_500_KBAUD
ISO_15765_29_BIT_500_KBAUD
ISO_15765_11_BIT_250_KBAUD
ISO_15765_29_BIT_250_KBAUD
SAE_J1939_29_BIT_250_KBAUD
The 4.2 models make use of the 6. ISO_15765_11_BIT_500_KBAUD
I don't know and can't check what protocol the 5.0 models use, but if it's not on the above list, there's room to enter a custom protocol.
Today some parts were delivered,
below a photo of it. The OBD2 dongles I was restricted to 8 pieces on Amazon, so I ordered later some more which are still on their way.
Also I started the 3D print order, they will be printed as the 2nd image below.
Firmware upload for the future is also improved,
it now auto-detects the correct COM port, and a selection menu for the units is made. See YouTube video below (There is a typo, can you find it?).
Great to see the parts arriving.
Unfortunately this means a load of work for Cabrio Bob.
Hope all of us being fortunate enough to have Bob make these for us are generous with the payment

Which is why I shall be dropping CB a few extra shekel's for his effort..I hope everyone else does too when we have the final price?
I'll give some immediate feedback (as doubtless Barnsie will too) as we are probably going to be the first to receive.
I'm not sure yet if there will be a 2nd run,
I do know that at some stage I will release everything so anyone can create one by themselves.
In some earlier posts I mentioned problems with the photo resistor,
turns out that the ESP32 can't operate all pins which are called "ADC2" as analog input when Bluetooth is activated.
The photo resistor is connected to one of these pins (GPIO2).
Since the PCB's are already delivered, I'm going to make a bypass with a wire to GPIO36, which will fix this problem.
In below picture this wire is just visible.
One other thing I found out, is that some ESP32 boards sometimes are having problems being programmed when the display is attached.
In the end it manages it, but only after 5 or 6 tries. When the ESP32 is detached from the PCB it is being programmed in one try.
Probably a power issue. (or I'm using a bad USB cable)
