Hi everyone, here's a quick dev thread with extra screenshots from the project

Today, I modeled up a little battery meter and implemented it into the dash. I tried to calibrate it as well as possible, it's reasonably accurate. I think it looks pretty good!

Other changes for today include: decreasing the window tint on the interior glass, and increasing the battery pack size to 90kW.

Cool vehicle name choice!

Can you please upload the images as attachments instead of using a 3rd party service (Imgur)? Then they will be stored here forever and won't be removed if the Imgur goes down.

All set

How does it work?

It works by using an oversized mapping of the fuel (battery) needle, positioned, sized, and rotated just right with a lot of trial and error to test calibration. The mapping is placed on some mesh inside the white outer border.

There was a comment about downforce being incorrect. This did need some adjusting and I should have ran these calculations the first time. This corrected downforce will be coming in an update very soon. Here are the new downforce numbers - if you like some light algebra, you will enjoy

Downforce Formula (informed by: https://www.engineeringtoolbox.com/drag-coefficient-d_627.html)

Fd = Cd * 1/2(p * v^2 * A)

Fd = Downforce (Newtons) (all of the below multiplied together.)
Cd = 0.23 (known drag coefficient value for the reference car)
p = 1.2 (kg/m^3) (air at standard pressure & temperature)
-- we can plug in any speed value we want. Will calculate these four
Scawen does rounding, so I will look for whole numbers --

v = 55 (m/s) - this is 198kmh
v = 25 (m/s) - this is 90kmh
v = 15 (m/s) - this is 54kmh
v = 1 (m/s) - this is 3.6kmh

Frontal Area (A) = 2.22 (m/s^2) (informed by: https://teslamotorsclub.com/tmc/posts/2217684/)

Downforce (198kmh) = 0.23 * (1/2 ( 1.2 * 55^2 * 2.22))
Downforce (99kmh) = 0.23 * (1/2 ( 1.2 * 25^2 * 2.22))
Downforce (54kmh) = 0.23 * (1/2 ( 1.2 * 15^2 * 2.22))
Downforce (1kmh) = 0.23 * (1/2 ( 1.2 * 1^2 * 2.22))

Calculated:
Downforce (55 m/s || 198kmh) = 926.739N
Downforce (25 m/s || 99kmh) = 191.475N
Downforce (15 m/s || 54kmh) = 68.931N
Downforce ( 1 m/s || 3.6kmh) = 0.30636N
