Would you want to own a sensor, which can measure the rotation of the motor or even control it so that it goes to the position you want it to be? Well, is time for develop your own magnetic rotary encoder, where you can use it to measure the speed of motor and let it rotate in the speed you want, regardless of the load on the motor! Cool, isn’t it?

Those components you might need are:

  • A magnetic rotary encorder v1.0 PCB
  • A 100nF ceramic capacitor 1206
  • Four 1uF electrolytic capacitor D55
  • A 10nF ceramic capacitor 1206
  • A AS5040 IC1
  • Six Green LED 1206
  • Six 560 ohm resistor 1206
  • Three 4.7k ohm resistor 1206
  • A 10 pin IDC header
  • A 10 pin IDC connector
  • Thirty-six 10 pin ribbon cable
  • A AS5040 magnet

For the soldering part, just followed the below instructions:

  1. The 10nF and 100nF capacitors have to be marked with blue marker, and then solder all the capacitors.
  2. You need to mark the 560 Ohm resistor with ‘561′ and solder it.
  3. The 4.7K ohm resistors will be marked as ‘472′ and solder them besides the 560 ohm resistors.
  4. Since the LEDs are polarized, you have to solder them in the correct places, where they will have green dots towards one side of the package.
  5. This is the hardest part, and you need to be careful when you’re soldering it. Make sure that they match up before you started the soldering process!
  6. These small guys are the tin-can shape things. Since they have polarity, so you have to double check before you’re soldering them to the board.
  7. Plug the IDC header to the board, and then solder it at the center tab.
  8. Lastly, do make an IDC cable and insert it into the header.

Hooray, you have just soldered a quite difficult board here, go and reward yourself with some cold icy beer! [source]
