Introduction: Simple Continuous Servo Modification
So I got through two Instructables only to find that it didn't really do what I wanted it to do.
What I mistakenly followed was actually, "how to change a servo into a dc motor" (whoopy!) I mean really?
and then "how to put some resistors in a servo" but then have to use a particular Arduino script to use it.
When all I wanted was to have the same servo do the same thing but just go one way or the other continuously.
Because then all the other project's I have on the go that use my servo's will work just the same but different.
Ya know ? same same but different !
So this is what has worked for me in this particular situation.
Tower Pro MG995 Servo motor. ( I don't know if it would work with any other type )
G.T.POWER LED SERVO TESTER.
and the tools
Small Philips screw driver.
Flathead screw driver.
A useless Dremel Micro with a steel cutting disk and later a 408 sanding bit.
If you don't have that, what right do you have being on this site ?
Just kidding, jeez your sensitive, you could use a hacksaw blade and a small file.
Step 1: Step 1.
Unscrew the bottom of the servo like so.
Then pull the bottom plastic cap carefully off.
Step 2: Step 2.
Take the motor out and the circuit board but be very careful doing this, only touch the edges of the board and carefully pull it a wee bit out to expose the little pot thing with the tiny philips head screw holding it in there.
And while holding the top half of the servo together with your other hand, unscrew and take out the screw.
After that you can use a small flathead screwdriver to carefully pry the pot thing out like so...
Step 3: Step 3.
Now I know some of you will be geeking over this with things like (shorting the board) and this and that.
But this has worked for me.
So there !
Now make sure the little pot thing is in the center like so and then while holding the top part of servo together carefully stuff the little maggit back in there like so.
I had to put it in on a angle so the circuit board would be in the same place (at the end where the colored wires come out end) but it was on a slight tilt as well.
Then put the bottom plastic part back on but don't screw it back together yet and place it up like so.
Step 4: Step 4.
Pull the top off while holding the base and middle parts down to expose the cogs.
Now with some tweezers take these two cogs of, only because the lube on the cogs is probably some really bad chemical that you don't want to touch. (I know, cause I did and it started burning a bit) Hmmmmm.
Now the only thing you want to do now is cut that nob thing off the biggest cog with the cutting bit on the dremal
or use a hacksaw blade, and finally sand it flush, or use a file to make it level with the rest of the cogs surface.
After that put the cogs back on and the top plastic cover and screw it back together and test it with the servo tester like so.
We have a be nice policy.
Please be positive and constructive.
