The Servo Controler
Servo’s are a good way to visualise what are you doin in the game. Doesn’d matter if it’s a little motion Base or a Dash with Speed, RPM, Temps, Fuel etc…
An easy way to control up to 16 hobby Servos are the Pololu Interfaces. There are different Type’s they work with USB or RS232, but you can easy connect an USB Converter to the RS232 it.
In this sample we work with an 8 Channel version without SUB D Connector onboard. You see the conection at the Image below:
Take care that the VCC is not too high if you connect the VCC Bridge!
Profiler 2.0 Setup
Now you just have to set the USO String at the Profiler 2.0. It works like this: ~255~~"Servo Adress"~~"Axle"~
The Servo Adresses from 0 – 7 will result in an 90 degree Action, Adresses from 8 – 15 gives an 180 degree Action – but it depends of your servo’s, so you have to try wich is best.
So if you have 4 Axis with 4 different Servo’s the String can look like this: ~255~~0~~a01~~255~~9~~a02~~255~~10~~a03~~255~~3~~a04~
At the Math setup you should use 1:1 GForce output’s with a maximum Calibration offset.
Some Pictures of the finished Servo Dash (without Cover)
The complete Dash
- -The red Gear is just to hold the Axis for the smaller Gear. The needle is just pluged into the Gear
- -For the Gear Parts i used a Vario Gear from Conrad, it has all you need (Gear and Axle Parts): 240788 - 62 / 7.10 Euro
- -To connect the needle, just cut a Servo Arm and glue it to the needle
