Starting a classical 2DOF Arduino/Sabertooth/24V DC

Humm. Good spot. Looks like the chicken and egg problem. it should go through a charger instead of directly the battery maybe. Better idea: switch to sabertooh 2*32
Any hints on the resistor to use to sink the current ? ohm/watt ?
Thanks.

After having spent some weeks on the arduino stuff, I'm back on the motion rig topic. I made a first draft using sketchup based on @RacingMat rig , using 40x20 metal. Something like that:


I then realized I needed something adjustable for the kids
Making the seat asjustable would be too much complicated for the gravity center, so it is the steering wheel that will need to move. So I found out the pieces must go ont into the other. I'm thinking of going for a 30x30 2mm thick with a 25*25 going into it and secured with welded nuts and bolts. This leaves 1mm to slide them one into the other. This will require the structure to be absolutely parallel. Any good advice to make sure it is parallel when ssembling ?
I'll post more pictures soon, once I have converted the current structure to 30x30 and 25x25

Thanks. I was thinking of using the seat rails I have on my static rig as they will become useless as the seat will be on fixed mounts. Same idea for the pedals in addition to the global adjustement using the profiles

here is an attempt:


I was wondering on the angle which I set to 60° on this design. Does it sound reasonsable ? more ? less ?

Here is the final "draft"


Should be enough adjustable.
Will get the metal tomorrow at FIC (french shop for metal). 6m long pieces (luckily, they can cut it on site)

it looks good!

you can find some dimensions here : http://www.xsimulator.net/community/threads/sharing-cockpits-dimensions.6789/

Wonderfull. Thanks. I'll make sure I'm in line with those models.

I'm still alive, just a bit busy with other projects (my wife broke entirely the bathroom.....no comment)

So I was finally able to get the metal bits:

18 meters total (for 30 euros): 6m of 30x30 , 6m of 25x25, 6m of 20x40
I'll cut them this week-end and check with my friend for a welding teaching day
Oh ! I also ordered some hall effect sensors, like the ones thanos is using on his AMC board. I like the contact-less thing with this approach.

Here is the final design for the moving part:


As I has exhausted the 6m of 30x30, I will use some 40x20 for the seat mount. Should be enough ?
The 500mm sliding into 450mm should provide enough range for steering wheel height. If needed I will shorten the 500mm after trying, in case I can't get low enough.
I'll adjust the 560mm depending on my seat mountand the seat angle of the back, but I should be pretty close with 560mm.
I attach the current sketchup file. If you have comments to make, make them now : it will be too late tomorrow

Keep doing first what your wife wants!
When I see your bathroom, I prefer not to fancy what she could do when she's upset!

Still alive, and bathroom has not moved an inch.....
But I started to weld the rig

At least I see now something starting. I jumped on it and it looks solid but I'm not very happy with my soldering skills, so I'll try again with my "teacher" when he comes back from his holidays
I'll put all pieces together, then he will review/correct the suspicious solders. Just to make sure and double-sure it doesn't break under rough tracks

learning by doing - I cannot say it better. When the rig is finished, your skill level has grown up for sure (in some cases too late ).

@vthinsel : are you using an inverter? or older welding machine?

inverter makes welding really much more easier!

and automatic helmet also

Yep, an inverter. Together with an automatic helmet. I plan to use this for house work as well.
This long week end I hope I Will weld a bit the sliding parts. Parallelism Will ne my moto...

Really good design, i love it, metal tubes and the way youre going to adjust pedals,

Wow prices for welding are very attractive !
It makes me want to invest

Some welding today, under a heavy sun

Max/min should accomodate adults & kids with no problems, even wih very long legs
I also found a cheap gimbal nearby (the garge guy has dozens..... for future projects I guess)
I hope I will have some time this week-end to weld the two mounts. Parallelism will be the key here.

In fact I'm using @RacingMat tutorial http://www.xsimulator.net/community/threads/from-atoz-2dof-arduino-wiper-playseat.4616/ as my starting point
Cross braces are needed ? Any picture so I can see what it should/could look like ? Thanks for your comments.
