Superglue for servo $50 robot

[Novice1]

Does liquid nail glue work as well as super glue on the servo  pot head for the $50 robot??

[sonictj]

It should just don't use so much that the glue gets in the way of the gears.  liquid nail is very thick.  I use white glue so that the bond is not permanent.

[Novice1]

wait, so I can use regular elmers glue??

[sonictj]

yah there is no stress on the pot so the bond does not need to be strong.

How do I remove the slot for my pot head, because I can't just pull it of cuz they made cheaper than the one Admin has, hteres no metal ring on it, it is attached to the gear.

[sonictj]

I won't be able to tel without a pic at least.

[Novice1]

Here it is, as best as I could draw it

What I do is I careflly drill out the slot, so there is no more slot anymore, just a hole.

Or just snip off the top of the potentiometer. That's what I did.

is this for hacking the servos? if so and you want to make it perminant you should try using regular resistors. i'd imagine it would be more acurate

it is for modifying them for continuous rotation.
regular resistors can be more accurate... but then you have to buy resistors and desolder/solder things...
this way is just easier...

I find this way to be more accurate, this way you can actually send a true 1.5ms pulse, adjust the pot so the motor stops moving, and glue the pot in. The resistor method usually requires you to diverge slightly from the 1.5ms pulse due to the inconsistencies between the resistors.

[SmAsH]

having the pot still in is a good thing, no soldering and the ability to adjust the hardware to accept proper 1.5ms pulses.

removing the pot is totally unecissary.  Its also not more accurate, because with a pot you can make adjustments while the servo is plugged in.  You just need to remove the gears.  I send the centering pulse to the servo while I turn the pot.  When the motor shaft stops Turing I glue the pot in place.  Its a piece of cake.  If you use a pair of resistors, and say they are off by a bit you can't adjust anything.  Plus its more effort.

I drilled it out, now they both turn. The problem is that they both turn counterclockwise!!! How do you make one of them turn clockwise, and the other stay the same?

[SmAsH]

both servos? if so, just flip one over... or change the code...
