Hey guys! Since I've got my servos, I've had two that I set aside for hacking. So, coming to my favorite website for help, I was sorely disappointed when I couldn't seem to find any instructables on how to mod a micro servo. After viewing a few, I went to my workbench and got to work. I was very surprised when I opened up my micro servo and found it to be slightly different then the bigger servos. So, I decided I would make a guide on how to hack into your servo! So what are we waiting for? Lets get started.
But then you ask, doesn't this defeat the whole purpose of a servo? Well, no. We just utilize the gearbox, so that we can use this motor as a drive motor for a robot. So now, let's really get started!
Step 1: Ingredients:
Ingredients needed: (no, not food ingredients unfortunately)
- Rotary tool or a utility knife
- Very small screwdriver (phillips)
- Soldering pencil* and solder
- Wire snips
- Needle noes pliers
- 2x 2.2k resistors
- Helping Hands (AKA 3rd hand) BTW check out this awesome instructable on making helping hands. Thanks rstraugh!
- 10 minutes
Step 2: Disassembly
First remove any servo arms, legs, and limbs from the servo.
Then, using a very small screwdriver, unscrew the four screws on the bottom of the servo. Be very careful not to lose these.
Watch the video for the disassembly of the gears. The top main gear my be hard in coming off. You can see I had a little trouble getting it off in the video.
