Small analogue sim pedals for:
This was the initial 3D concept from Blender:
right-click and drag to rotate the model, left-click and drag to move it around,
and middle-click and drag to zoom.
i switched the potentiometer for the brake around the other way to save some space
between the pedals and make the offset for each piece less. heres a 3D model and below that,
the first working prototype.
"working" is a bit of an exaggeration - at first i couldn't even get it calibrated, and it all all very
uncomfortable and fragile. but for a few minutes at least, i had pedals!
stage 1 refinements:
first i improved the springs.
the clutch spring was way too heavy, so i made a new leaf-type spring from a P.E.T drink bottle.
the brake foam was getting crushed, so i got some better foam and fitted a leaf spring over the top of it.
the throttle was getting stuck down by errant bits of Blu-Tak, so i cut two tiny squares of awesome art-grade
double-sided tape and anchored the spring with them.
when i reached forward to hit my look keys in LFS [q, w and e] i had to lift / slide my wrist a bit.
without that weight holding it down, the base would tip up and the aluminium plate would fall onto
the keyboard, usually pressing keys like a marauding cat.
so i added a 'roll-bar' [hacksaw blade] that would stabilise it, at least for throttle-pressure,
and still slip under the keyboard.
the metal pedals were cold and a bit slippery, especially for fingernails when reaching for the
most distant keyboard binds while whizzing down a straight. and metallic fingertips taste worse than they smell.
i used awesome double-sided tape to attach little pads of different materials to the ends of the pedals -
paper for the brake, cloth for the throttle and pure linoleum ore for the clutch.
this feels much better, and can be replaced at whim.
the wristpad was an extension of this luxurising, but probably made the biggest ergonomic difference of all.
its a big thick chunk of that regularly-undulating packing foam, attached with a strip
of the same double-sided tape.
it is soft, warm and non-slip, and most importantly raises my wrist and improves the
ergonomics massively - everything is much easier to reach, fatigue is BALEETED, and
the wiring drops down out of the way.
finally i rewired it with extra super heavy duty stuff. i like heavy wiring.
also important to do is cover the potentiometer pins in some tape so you
cant touch them. it makes the signal go haywire and pulsate / peak.
this is a demonstration. i shot it with my webcam and fraps, the later absolutely butchered LFS's sound.
i would never do such a thing to my XR GTR =(.
you can hear the duck-whistle dumpvalve though XD..
thats about it for now.
some cool doods have expressed interest
in this experimental hardware, and a few have enquired about purchasing a set of thier own.
i'm cautiously enthusiastic about this, as i have no experience in selling things and dealing
with "customers", but theres only one way to find out if it'll work or not...
if you've read this far, thanks. and if you want [god forbid] more information,
you can email me at firstname.lastname@example.org, subject: 'pedals' so i dont assume its Pre5scr1p7i0n p1lLz.
BACK TO THE LAB!
Martin, from lands distant and exotic, designed and built his own fully
custom set of pedals, with some electronic help from his friend I believe. It uses hall-effect sensors
instead of pots, and little hole punches for the pedals. A lot of work and lateral thinking has gone
into this very polished and impressive device :)
hall sensors from a computer drive...
the neodynium magnets run vertically on these pins
"they are made from "sim card" cutters... ...things on the end of red/white cables are halls sensors
(dismounted from old cd drive)...
...hall sensors are attached right under neodymium magnets... ...they grab magnetic field, which is converted by LM358.
Nowdays, pedals are fully working, no shielding needed... ...i have only two pedals - gas/brake. maybe next step will be
clutch axis assigned to microswitch. dunno yet :)"
