    Hey everyone,

    I've been building/testing a seat mover for the past week or so. At first it wasn't much to look at: had a simple 9v battery powering my motoMonster to output some current to a simple motor I salvaged from an old xbox controller for vibration.

    [​IMG]

    I had weird issues with the motomonster not outputting the right voltage, I believed it was my battery's fault so I upgraded to a pc power supply, jumping the 24 pin to allow current to flow and splicing an old molex connector. I also took a dive in buying more appropriate hardware to solidify the wires connection as I was mostly just letting the wires hang from the motoMonster port before..

    [​IMG]

    But then again, the weird output problem came back so I inquired about it on the forum and noorbeast was very helpful giving me link to test my motor controller wich was the issue. I ordered a new one and I'm going to test it as soon as I get it. I figured out, since I'm so far out in the project, I would need a beefier power supply so I opted for a 600w one from amazon. Using the spare time, I went to the junkyard and found 2 wiper motor and a universal joint. I'm aware the motors might not be powerful enough but it's a start and it was cheap.

    I've ground isolated them and found the appropriate wires for high speed function. Got my new motoMonster and power supply. The controller works as expected at 12v on both outputs. I'm glad it works well, if it had been a faulty one I would buy a real one instead of a cheap knock off, but I'll wait and see if it last.

    Everything is now wired and seems to be working well. I'm looking foward to building the seat. The wiring and programming had me the most worried, the rest should be going smoothly.

    Here's a video of the working wiper motor on the 600w power supply.

    That is a great start :thumbs

    Do add heatsinks and fan to the MM ASAP, or otherwise your risk burning it out.

    I'm awaiting a set of tie-rods that should come in this week. I should be building up the mechanical part of the seat mover later this month as the whole corona stuff as been slowing things down for me. As for the heatsink, it as been added and the arduino/MM board have been hot glued to a power supply box. The old power supply switch will actually be used to power up the remote 600w power supply, I think it's a pretty clean setup.

    Received my tie-rods today, greased them up and tried out what I think is gonna be the arm on the wiper motor. The motor arms are spare bracket clamp for hydraulic hose I had lying around my toolbox at work, they seem to fit perfectly, have 3/8 NC threaded holes and they even are taper for the motor shaft!

    Can't wait to start building the universal joint bracket and motor brackets. I want to weld the joint onto a small 4x4 1/8 plate, bolt it to a MDF base wich will be bolted on my GT Omega Art and same goes for the other side of the joint that goes toward the seat. I still need to plan a bit more about balancing it out or maybe just eyeball it all and fine tune later (famous last words).

    Good build! As noorbeast already mentioned heatsinks on MM is a must, I would even suggest adding active fan + if you are planing to give motors more amps and wire MM in bridge config it will be needed. my solution bellow and link for wiring

    So I've been working a lot on the motion sim lately, sadly the wiper motors won't be strong enough. The weight transfer is too much for them to handle and they reverse when weight is applied to them. Also the base plate constrict the travel of the motor rod-end and I simply don't like my welding of the u-joint.

    I've got the sim working with LFS though which is nice. I have to make it sturdier and invest in better motors. I'm thinking of mixing some 80/20 as a new base and making the setup look more professional as it looks very flimsy at the moment.

    Here's a photo of the setup before I tear it down for upgrades.

    I bought 2 new motors. I'm still thinking of a good way to secure an arm to the motor shaft, if anyone has done it before with a motor from pgsaw and has some input that would be nice.
