How about a little bit of Titanium?

Now that's pretty cool! How much movement does it take to make it shift?

Less than zero. :-)

It can pick up a finger from 5-10 mm away. Even through gloves.

You post the most interesting and thought-provoking things!

I think I understand the paddle design pretty well. (Fixed paddle position is so much simpler than having them move with the steering wheel. Apparently that decision drove you to make each paddle cover a wide angle.) However, I don't understand what you've posted about an LED window. Are you saying there's a display to tell the driver which gear they're in? Or to advise that a gearchange is recommended? Or...?

5-10 mm away. Neato! But will sensitivity be easy to adjust? If it detects your hand when you reach for the turn signal stalk...

The stalks are well outside of the paddles (which have a 9-1/4" outer diameter). Each paddle is connected to one sensor circuit. (Two circuits on one card.) Each sensor circuit outputs a grounding pulse when a touch is sensed. Each output has a board mounted LED that lights during the grounding pulse and the window allows you to see that the board is generating an output. Won't be very visible when driving unless you intentionally look at it but useful for troubleshooting if needed. Since the LEDs were there I installed a window for them made out of smoked plexiglass. The same stuff I'll have over the gear position readout.

Speaking of which, I have a 7 segment LED numerical readout and driver chip which I am embedding in the stock (modified) brake warning light and switch. The bezel isn't quite deep enough but the fit is good otherwise. It's an old bezel though and like most of them the silver is gone. I may paint it black. Anyway the indicator light is now an LED and is hooked to my WB-O2 sensor. I installed a micro tactile switch to replace the old contacts and have the button between the red lens and the 7 segment display. That is the calibration switch for the O2. Then the display sits on the right end of the bezel and I cut off the black rocker and squared it up to match nicely with the smoked window. Still some work to do to finish it up and connect the lead-out wires. I got an AMP CPC series 9 pin connector for it which should fit through the cutout with just a smidgen of dressing down of the back shell.

So yes, I will have a digital gear readout, 1 through 8, blue, with 0 for neutral and park and flashing for reverse. Maybe a flashing 9 or else zero, I haven't decided yet. Maybe a flashing 8. The display also has a separate lead for the decimal point, so I have another built-in LED indicator I can use for something else if I want to.

Jim, neat. Are you going to have false shifts when you get your fingers to close ? I would be forever shifting up and down because I am forever flexing my fingers.
You going to bring the car to Indy ? I think a lot of us would like to see/hear it.

Can you turn the paddle shifter off if you want to be lazy, or let someone clumsy like me drive? Also, using the 8 for reverse might be good... it has the elements there to make an R.. Is that possible? An 8 kinda looks like a B, for Backup

My LE steering wheel is 14-1/4" diameter so that puts the paddle 2-1/2" inside the steering wheel and it's also set back about 2". It's a short reach for sure, but unless I have fingers flying off the back side of the wheel I'm not going to hit it and maybe not then. Right now I'm a little more concerned about the possibility of flashing the headlights getting the stalk close enough to trigger a downshift. But it might not be a problem as the stalk is not grounded.

I'm expecting to have the car back on the street shortly after the weather breaks but whether or not it's ready for Indy depends on more than just me so I can't make any guarantees yet. Still have a few issues to deal with but we'll see. It'll be there if possible.

Jim

The car should run in standard Auto mode unless you touch the paddles. Then I think there is a time interval that can be set for manual mode that will time out whenever I set it to. There is also an input to select Auto or Manual mode but I haven't done anything with that yet. Might be handy for stop and go traffic. Maybe I should hook that up.

Jim

Installed and tested:



Jim

Cool! No problem with the dimmer switch?

Nope. None at all.

Jim

Jim. That is amazing!

I just want to play with them!

Dan , I am sure you are thinking about plying with the shifter while under power.

people who play Tesla coils are normally more into heavy metal.

Got a U-tube link for the tesla coil players?

Jim

Or Southern Rock. ;)
