Le Poupe Active Air Brake Spoiler Concept

[BigMike]

I was thinking about the toilet seat brake activated air brake/spoiler last night and I think I have a good idea.

The simplest way would be to have a direct cable-linkage system connected to the brake pedal itself, but this is a safety issues in the event the spoiler system jams and prevents the brake pedal from moving.

So the next idea would be to use a servo or some other electric motor and use a trigger system with our brake pedal. But this would be complicated and we'd have to account for how much a setup like this would cost against our $500 budget.

So then I had this great idea! Let's use some large vacuum diaphragms!!!! Think about it, this is the perfect solution: When you need to brake, you shut the throttle which maximizes the intake manifold vacuum! I bet if we ran 2 or even 4 diaphragms we could power 2 toilet seat air brakes without any trouble, and vacuum diaphragms are a dime-a-dozen at the wrecking yard

Here are some examples on YouTube of an air brake spoiler:

Insted of vacuum diaphrams, use pop up headlight actuators. We have a few sitting around here.

[BigMike]

ahhhhhh that is a great idea! Those actuators are pretty powerful, right? The good thing is that the car came with them, so it's no cost at all!

[BigMike]

Hey, I didn't notice this earlier (I posted in a hurry), but the 2nd video posted above (yellow car) has a split spoiler that is used also to help with cornering. We could apply this concept to our dual toilet seat idea also.

Differentiating spoiler!! SAWEET!!

I want to build a prototype for the LeMons car and a final version for my own car. I think it would be awesome to have an active spoiler on my own car

[Sirdeuce]

Two toilet seats opening separately in turning, and simultanious on braking?

[BigMike]

Yes Sir!

We can hook up an accelerometer to my BASIC Stamp microprocessor and program it accordingly.

[BigMike]

I'd like to build a first basic prototype for the March event which is just an air brake only, not a turning spoiler.

Once we prove the concept works and can make it an entire weekend, we'll try the split seat idea
