You're almost there... just 2 end-stop-like switches and bob is your uncle. :-)

Pity you wouldn't be able to regulate the push/pull forces of the springs.
If you'd consider using some threaded rod (M16?) instead of steel tube, you'll be able then adjust the tensions with extra nuts and washers.

After 2 years ago of my first own pedals, I'm making the new version... "pedals v2" :p
I used the first one from january of 2015 and now it's time for this new model.
I took this proyect from internet but only images like this:

So here I'll post some images Smile

Each pedal is independent and is mounted on a base, I started with the clutch

I used an square pipe (50 x 30 mm)

this piece form a sort of hinge with the one already welded in the pipe

the small hose will be used as a guide

parts with corresponding screws

assembled parts

pedal

each pedal use a spring like this one

this rod center the spring and gives the possibility to adjust its hardness

and there's the clutch!

I did the same for the throttle

The brake is a bit different (60 x 30 mm)

Hardness increases gradually (like real brakes)

these parts duplicate the rod travel

Pedals are done, now the base...

Strong as hell Big Grin

and all parts assembled

These screws are to adjust the position of each pedal side by side

and comparing the old v1 with the new v2... (weight -> v1 +-5 kg, v2 15 kg Big Grin

)

and a short video Smile

Now I need to add the electronic parts. I wanted to use hall sensors but in my small city I can't found, so I guess I'll use potentiometers...

Next week if I add this I'll upload some pics and yes, after it gets finished, some black and yellow paint will be great Big Grin

Nice one!
Could use some sound dampening though. Some felt cloth or rubber padding under the washers and dab of oil here and there :-)

How about opto-coupler as a hall sensor replacement?
You just put a LED on the one side, photo transistor/diode/resistor on the other and the gap (elongated triangle shaped) between them, moving with the pedal.

How much does this thing weigh? Looks hefty Big Grin

Energy, you done it again!

Yes! the throttle pedal need some oil and I'll add something on the hose, maybe vaseline Big Grin

That's interesting, I'll read a more about because I'm a bit tired of the potentiometers...

I guess that's your answer Big Grin

Hehe thanks man! now I want finish and use it Smile

RE: Energy inventions oO - Seven - 01-25-2016

Rather than oil or vaseline, try silicone lubricant. Silicone lubricant dries as a thin layer of low-friction silicone (would you guess?!) rather than just drying up, it's the same stuff you'd use to keep window runners on your car nice and smooth for example. About the same price as a bottle of WD40 really from any auto/DIY store.

Righto... Text got swamped with pictures (said trying to make an excuse for his blindness).

RE: Energy inventions oO - Vim Fuego - 01-25-2016

Energy, you are an engineering genius - that's brilliant. They look like they'll last at least 50 years or more Big Grin

As an alternative to Silicon or other types of grease, you could try graphite dust as a lubricant. It's completely dry, so it doesn't collect dust and dirt. Use a fine sandpaper to grind the lead of a pencil down and sprinkle the dust wherever needed.

RE: Energy inventions oO - Energy - 01-26-2016

thanks for the nice comments and suggestions guys! I appreciate them Smile

lol next time I should use another fount (?

RE: Energy inventions oO - Energy - 03-04-2016

Annnnnnd... finally I got the time to finish the new pedals Big Grin

I used potentiometers to get it working... and some black and red paint because I haven't yellow e.e
Some pics of what I did Smile

Plastic of an old pc speaker let me hide electronic parts... (that black thing)

Now I should get the time to use it Big Grin
