Brought the PRNDL indicator and reverse lights online.

Working on making the vehicle street legal.

It's an Arduino microcontroller with a potentiometer reporting shifter position. When the shifter is in R position, it also triggers a Mosfet relay that turns on and off the reverse lights as needed.

The display is an I2C 1 inch screen amplified with a lens and packaged in a 3D printed housing. It gives a unique look that I feel adds to the cyberpunk aesthetic.

Would you mind sharing more info on the potentiometer setup? What style, how it’s mounted, etc?

I have a b&m shifter that I’d really like to add an indicator.

I think you need also a Split-Flap Display somewhere in the dash

You're unhinged in the literal best way. I love this.

Yup. Bentley CRT used to display speedometer data.

Might add rpm if it feels right.

Is there any way to assign different layouts and different gauge readouts to different channels on the TV?

[-]

Vengeful-Wraith@reddit (OP)

Huh. Interesting idea. I see no reason why not. I'm not sure how you would. Maybe dedicated hardware for the data and then that reports to different RF frequencies?

It might be a lot easier to cycle through presets on the hardware that's exporting to the RF modulator.

Easier, most likely. As satisfying as Click! Click! Clicking! through the channels? Highly doubtful.

[-]

Vengeful-Wraith@reddit (OP)

With that said, you could use a click position potentiometer, or a rotary encoder that replaces the stock click dial. Similar feel, easier coding.

You should cross post to the crt subreddit. We love that shit.

[-]

Vengeful-Wraith@reddit (OP)

I should. Someone recommended cassette futurism as well.

Crazy idea to amplify the OLED screen with a lens but I love it!

FortuneHeart@reddit

Shift selector gauge details? That looks incredible with the CRT

r/lego - we can make anything look like the Millenium Falcon

r/projectcar - hold my soldering iron

There's a Facebook AI bot called, "An improbable future," that does stuff like this. Here you are doing it IRL

No one? Okay ill bite.

Whats up with the rear pushrod suspension on a 3000gt? Where can I go to learn more about this build.

Looks sick man! Keep up the good work!

[-]

Vengeful-Wraith@reddit (OP)

The pushrod suspension was simply a fun challenge to design. I've also made it very adaptable to aftermarket coilovers.

It's managing a Ford 9in solid axle underneath.

I don't really post anywhere else. Just this community mainly.

I just watched your walk around video... there was not a single moment in that where I was able to anticipate what was comming next. Rad dude, keep it up! Thats real Hot Rodding!

[-]

Vengeful-Wraith@reddit (OP)

Thanks! Gotta keep em guessing!

I invent as a hobby, hence the cacophony of random challenges in this build.

[-]

Absolutely loving this! What’s the suspension in the back for?

[-]

The rear has a solid axle which won't work in my case for coilovers. I also wanted extreme adaptability for different coil and shock products. So, I designed a bell crank, inboard suspension. Two thick rods push up and the bell crank redirects the force backwards into the coils.

If you mean the use case, than purely for a fun engineering challenge. I've only really seen my setup on off road vehicles and showy vehicles.
