Building a Magnectic actuating, force feedback yoke, need held writing the software

I have plans to build a magnetic actuating yoke that will not cost $1200 and have up to around 10 pounds of resistance and my goal is to price it around $200 U.S. But need help writing the software. I'm sick of the yoke makers building yokes, promising consumers prices and then selling them at nearly untouchable prices. Those of us who's wives would kill us if we spent anymore money on our passion/hobby or $1200 for a single item for our hobby kinda guys. Uhhh... it makes irritated just thinking about the prices of these yokes that do not cost even a eighth of the price to manufacture.

I'm a real world pilot and I still fly my sim because it keeps me proficient and I feel like I never take time off from flying a real plane. Most of flying anyway is habits that are ingrained to the point of being a reflex, I'm a checklist n4zi and they are you're best friend in a plane, but having the realism of accurate yoke inputs and forces just adds to the OH YEA!!! of flying.

So your on approach at night with trees surrounding the runway (literally looks like someone cut a rectangle out of the trees and dropped a runway) and you see the threshold coming into view under the glow of the landing light. As you dip below the green tops you start flat descending and at a scary rate. That upwind flow that let you make a nice, slow approach abruptly dissipates. You pull back only to hear the stall horn, you FEEL a lot less resistance on the yoke than before. Then you slam the throttle through the firewall and that control resistance comes back just in time to blacken up those stripes a little more.

True story, my scariest experience yet. If you can use the plane again, it was a good flight. Anyhow, thats the experience I want to achieve with a yoke but at a wallet friendly price.
