Hard Drivin' brake pedal

(1/4) > >>

Shrapnel:
Hi everyone! =)
I'm working on an original Hard Drivin' upright cabinet, but I found the brake pedal to be 'empty'. =(
In other words, there's nothing apart from the pedal itself and, from what I understood, there's a 'load cell' missing that should handle the analogue braking.

Since I haven't found any spare parts around, I was wondering if thins thingie:
http://www.robot-italy.com/it/force-sensing-resistor-0-2-circle.html
could do, but I'm not sure at all and I'd like further opinions. It's an Italian website (I'm from Italy, so...), but the item description is in English. =)

Can anybody help, please?
Thanks in advance!

Hard drivin' upright (compact) brake is a simple microswitch, not a resistor. Take a look at the online manual. The sitdown (cockpit) version is different and uses a potentiometer. The piece you linked is likely to work on a Atari badlands cab.
If i remember well when you press the pedal the switch goes open (it's more than a year that i fixed mine).

Post a picture of the back side of your brake pedal.

 Im not sure about the standup...  however, the sitdown isnt a pot.  It has an actual pressure sensor on it.  I believe the brake sensor has far greater a range and accuracy, that a pot has.

 The gas is a pot.. and I think the Clutch is also a pot.

Well if that's true it's even more of an indication that the designers of the game had a screw loose.  If you want one pedal to have greater accuracy than the others, you want that to be the gas pedal.  It wouldn't surprise me at all though, because the Drivin' games are weird.

 Not really.

 Gas is fairly relative to the way that the engine limits acceleration.   This is why a lot of games can use digital gas, and get away with it.


 The brake however, is a completely different story.   The brake isnt limited by anything... so theres no delayed responses.
Much like the brake on your bicycle... you can press it a hair, giving a tiny amount of friction,  or really crunch it, for max stopping power.    Mechanically with cars.. you can press the pedal nearly to the floor.. and keep pressing really hard to exert massive amounts of hydraulic pressure.

 In many racing games that were in the arcade.. you barely ever used the brake.   The reason for this, was due to the games design.. which allowed for near full speed on turns... and low level of traffic.  Often an unrealistic drop in speed when simply letting off the gas.. with no real momentum factored in.

 In RD, you have to consider not only the g-forces, but also the weight and vector of that weight.   Even if you let off the gas... going 150 mph,  your not going to slow down like 50 mph in a seconds timeframe.. unlike a game like Outrun.

 Race Drivin uses a microswitch and a Strain Gauge.   The strain gauge is specially bonded to the pedal itself.
I believe it used the microswitch to start the process of checking the strain gauge.  Keeping any issues of de-calibration from accidentally slowing down your car... by ignoring any sensor readings until the pedal is pressed past the microswitch engagement.

 - Furthermore... its hard to take your sharp words as nothing more than a troll..  or simply pure arrogant ignorance.
I dont believe you can hold a candle to developer  Jed Margolin’s  intellectual abilities, and actual accomplishments... let alone the others involved in HDs creation.
