The tools alone will take up too much of the budget. Then where are you getting this material? From a dumpster? Okay, so you got to buy wood, and wiring, little servo motors, soldering tools. Where are you building this? In your garage? What if you live in an apartment building? Most of those places don't have outside power, so I guess you are building this in your living room? Sounds messy with all the sawdust. Not to mention how much time you are wasting tinkering around trying to make this contraption work and have moderately accurate inputs? You would spend less time and money going on to craigslist and buying someone selling their $150 cheap sim-rig and wheel and you just plug it in and go.
Yeah, certain parts of the world do not have easy access to all the components for a sim rig like we have in the US. In my area, I can pick up someone's used sim rig pretty darn cheaply, plug it in and be playing in minutes. This guy's solution is likely out of necessity because buying a wheel and pedal setup in his area would be equivalent to a month's pay.
