Default Glowing disc brakes - How To.

1a) The wiring is tapped from the motor with a 210ohm resistor.
1b) Brake disc glows only when motor running.
1c) i would suggest doing 2 discs extra. eg: require 4, do 6. require 8, do 10... unless you're confident tt there's not gonna be any screw ups.
1d) the leds are fitted onto the hubs. use yr imagination for the location. just remember to leave play for steering and suspension travel. i encased my wires in heat shrink.

Steps taken:


1) the discs are stuck on the wheels. Will make another set to be fitted on the hubs nut so disc can be left on the chassis. only consideration is that the chassis has to be elevated wen maintaining. plus point is that you can take alignment for camber, caster, toe-in, toe-out settings from the disc themselves. the discs were drawn on the computer on a 1:1 scale. to make them fit on my mini, the external diameter was reduced to 35mm. full sized touring rims can accomodate up to 40+mm.


2) the drawing was then printed out. i decided to do slotted. they don't succumb to structrual or thermal fatigue under race conditions. to cut the styrene/plastic sheets, i use olfa's circular and a perspex cutter.


3) the drawing was taped to the styrene/plastic sheet.


4) slots were scored on first. don't score too deep if you are using brittle plastic. it was be hard to break the tabs off later.


5) run a few rounds with the circular cutter. again, you are scoring. score deeper. it does not mean press harder, it just means go round as many times as you can until: a) your patience runs out. b) you have cut through. you don't need to score through, you will GENTLY bend and break the unwanted bits off. remember, yr patience need to stretch for 10 holes.


6) wet sand to matt the surface. u want it smooth and translucent.


7) this is wat mine looked like after. or rather, how i imagined it to look like.


8) glued onto the wheels.


9) fitted onto the car with leds on.


10) running.


11) running without ambient light.


12) stationery. i used orange leds to more accurately depict the col of glowing discs.

important to note: disc are glowing due to heat build up. try not to work on them until thy are cool to the touch. becareful not to burn yourself.

there. done.

Very nice[sm=thumbs_up.gif]Nice pics and guide.
How about a making a reflector behind the leds.You could make something simple out of tin foil to test the difference.

since it's mounted to the hub, there really isn't a whole lot of space. not for me anyways, considering tt i'm running a mini chassis with wheelbase 208mm. my tire is 53mm in diameter. so there. what would the purpose of the reflector be for? you could use a silver countersunk shim in you want. i'll get a pic up to show u what i mean....

That is way cool! How did you come up with the idea? I may have to make a set. Even if I dont lite them up, it would still be cool.

Ah didn't realise it was that small.Hope i didn't offend you,was looking at the last couple of pics and was thinking if you had some sort of reflector behind the leds then you would not get the shadowing of the suspension showingThe disc would be an even colour.
Have done a rough mock up below,can you see what i mean?

no offence! not at all. i was just curious abt the idea of the reflector. ok. i catch yr drift... but even if there was a reflector, it wouldn't help much. been there, done that. because it glow would still be ard the leds. that's the reason i used clear styrene and then matted it down, i know the light is not evenly distributed, but it's obvious enough when it's running. anything else tt i have tred, was too complicated.

Ah yes i'm saying use the reflector idea and the sanded disc together.
Lol i tried to shape the tin foil in my pic to the size of your matted disc,the black dots would be where the led's are mounted.

getit. but you'd still get 'hotspots' cuz the leds have a fixed angle of light throw. and it's quite narrow.

I'm thinking if you angle the leds and shape the reflector accordingly you could create a more even spread of light(but then you'll need to add calipers to make it even more realistic)
Lol you know it only took 2 mins to make my mock up?Please try it,even if only to shut me up!
