An Advanced Hardware Hack
If you plan to attach a servo to your ELEV-8 v3 and use it in flight, it is a good idea to give it its own power supply. With a few components and a little soldering, it is easy to build a power supply for your additional servos.
DO NOT PROCEED unless the propellers and battery have been removed from your ELEV-8 v3!
- Gather your materials.
- Carefully study this diagram:
- To begin building the power supply shown, cut a red and a black jumper wire in half.
- Take one half of a red wire and one half of a black wire and cut them in half again - be sure to save all of the pieces.
- Strip the cut ends of all of the wires so they can be soldered.
- Solder the wires to the components as shown in the diagram above.
- Use electrical tape or heat shrink tubing to wrap up exposed connections and keep them from touching each other and shorting out.
- Connect the power supply you just built to a 3-pin header on the ELEV-8 Power Distribution Board. You may need to remove the flight stack from the ELEV-8 v3 to reach the connections:
- Connect a white (signal) jumper wire to the top pin on the header your servo was originally plugged into on the ELEV-8 Flight Controller:
- Connect the white (signal) wire and power supply to your servo as shown in the drawing above.
- Turn on your transmitter.
- Connect your ELEV-8 v3's battery and veryify that everything is working correctly.
If you hear any popping or hissing, or smell something hot or smoke, immediately disconnect the battery!
DO NOT FLY Your ELEV-8 v3 after modifying the hardware or firmware until you have completed the safety testing on the last page of this tutorial!
