Hello there,
as already announced, I updated my CSR Elite wheel base with a real size wheel and a 3d print button box, magnetic shifters and wheel/base adapter.
To do so, I had to "extract" my old wheel pcb to an extern box (the old pcb is necessary for the wheel base setup, calibrating etc.).
When I did this, I took the chance to give a little maintenance to my wheel like cleaning (the plastic cover on the back was sticky), lubricating, fixing loosened things etc. as it was not opened for almost a decade!
As the air which is pumped into my Buhler motors is clean/dust free, the motors look like new from the inside while the rest of the base has a patina of dust.
I searched in THINGIVERSE (.com) after a CSR elite wheel adaptor and a button box with shifters. A friend just printed the parts and then I took an Arduino sketch for a button box with rotary encoders from XSIMULATOR (.net).
After cleaning all parts, attaching all button switches, rotary encoders and wiring everything together I´ve put the wheels on a scale.
the original wheel was 1.097 kilogram and the new one was 1.564 kilogram.
I have a 3 ribbed belt as spare part, but I left the original 2 ribbed in the wheel base as it looks still ok and the change would have been a lot of work. The 2 ribbed belt seems to get along with the additional weight and is more "agile" or smooth than the stiffer 3 ribbed belt.
You can source all needed parts like switches, encoders, neodymium magnets, spiral USB cord, Arduino nano etc. cheaply online (China makes it possible!). I gave my friend for 3d printing 20 Euro and spent 30 Euro for the steering wheel, the electrical parts, screws and magnets were another 40 Euro so I finished the wheel for around 100 Euro plus working hours. The pcb housing was made out of remaining material from my workshop.
The new wheel is a bit ... let´s say softer in reaction compared to the old, lighter wheel which was just a playball for the Buhler motors resulting in a bit "nervous" behavior but the precision of steering feels enhanced (due to the bigger diameter?).
Steering details like understeering, track surface, dirt or curbs feel now more realistic, imho.
On top it´s more solid/robust and feels not longer like a toy.
In terms of building I can say that it was relative simple with no traps or hooks - I left the shifting paddles in "testing shape" and will exchange them with better ones by time.
If you want to build it and you do not find the files, I can support you - please contact me.
@rokkon: you should consider building this wheel instead of repairing the old one as it gives you enhanced gaming pleasure!
Keep on racing
