Here is an action shot of version 1.0 of the "final" mechanics design of singe pointer gauge.

If you watch carefully, you can say there is about 0.5mm free play in gears...
Movement of the pointer is smooth in real life, my videocameraphonethingamajig makes it look choppy in video.

I think next gauge will be more accurate and I will also add functions to correct slack in software.



Let's see. The current status of project is:

CAN-bus

• Signaling/message sending ok
• Messages need to be defined, 50% done
  

Servo control

• One servo control ok
• Multiple servo control 80% coded
• Continuous rotation modifications for servos studied and tested to be working
  

Rotary encoder

• Reading encoder ok

Continuous rotation sensor (for continuous rotation servo position detection)

• Reading value through AD-conversion coded
• Sensor has about 60degrees where the value is random, needs to figure out how to use two sensors in one axle to get accurate readings.

To Do

• Count how many servos need to be modified for continuous rotation
• Modify servos
• Build mechanics for the rest of gauges
• Draw schematics and layout for gauge control board
• Integrate tcp-stack to master control board sw
• Start designing radio stack
• etc.
