Comma AI self driver assistant

[rootusrootus]

So I ordered a Comma Four, and I'm about to pull the trigger on the coupler. Is there anything else I should get to make this a better experience? I've heard occasional mentions of longer cables, but I'm having trouble finding an authoritative answer. I want to make sure I have everything I need when the Comma finally ships.

It should ship with the correct cable if you order an F150 kit. If you just order a Q4 development kit you will need the long cable.

You may have to get your own cable but I'd try the stock cable first, if you absolutely want to do it first go, you could buy another ?thunderbolt? cable, and return it if you don't need it. Took quite a bit of plugging and unplugging and turning but the stock cable eventually worked fine for me.

I chose the f150 when ordering, says it comes with the q4 harness, and the comma four comes with a 2ft OBD-C in the box. Thats all we need? Dont we need a longer usb c to go from under the dash to above the mirror, or am I mistaken?

I was planning to buy this Cable Matters 8ft USB 3.2 TB4 cable.

A thunderbolt cable is not guaranteed to work. Like USB C there are different generations of cables. Look for a USB- 3.2 gen2 cable.

it Should come with a long cable. You can buy one to be safe but the one you linked is not a gen2 cable

yeah, i was unsure hence surrounding it by ??

How many people would be interested in a quick release dock for the C4? Comma claims it's more robust and can be left on the windshield 24/7.

I would buy one. I'll be buying Comma 4 as some guinea pigs have tested it first.

Would you ever consider selling any of your 3d print files rather than the printed object itself? I only ask because I have a 3d printer myself so it wouldn’t make sense for me to buy a 3d printed item.

I have no interest in taking anyone’s design to sell it myself, but I understand why you wouldn’t be open to sharing the print files.

I make all of my designs free after I recoup my cost to do the design. But as an example, I spent 100+ hours, wasted $75 worth of filament on prototypes that didn't make the cut, and spent over $150 on dozens of different USB cables from amazon, ebay, and AliExpress to develop the Gen2 Comma3x Dock. I have to sell some before I give the design away.

There is a chance the comma 4 dock will need a custom PCB to work, in which case the STL files will do you no good without buying the custom PCB from me. I try to avoid custom PCBs so the dock can be repaired easily, but the way comma did the design for the C4, it is going to be hard to do with off the shelf components.

In my Thingiverse profie you can see all of m files including the Gen1 Comma3x Dock and the Expedition Shifter files I have made public. The Gen2 Comma3x Dock was always going to be posted in January, even before the Comma4 was announced.

Understood that all makes perfect sense! I will check out your design page too.
