| - | HiTEC HS-645MG servo before modification | + | |
| - | + | ||
| - | {{::servo-modify-000.jpg?nolink&500|}} | + | |
| - | + | ||
| - | no soldering, no cutting, no part replacements..... | + | |
| - | + | ||
| - | !!! the modification is **reversible** (if you keep all the parts and don't damage anything, of course) | + | |
| - | + | ||
| - | ==== step 1: remove the screw which holds the arm ==== | + | |
| - | + | ||
| - | + | ||
| - | {{::servo-modify-001.jpg?nolink&500|}} | + | |
| - | + | ||
| - | ==== step 2: remove the arm ==== | + | |
| - | + | ||
| - | {{::servo-modify-002.jpg?nolink&500|}} | + | |
| - | + | ||
| - | ==== step 3: remove the 4 bottom screws ==== | + | |
| - | + | ||
| - | {{::servo-modify-003.jpg?nolink&500|}} | + | |
| - | + | ||
| - | ==== step 4: take the top and bottom part of the casing off ==== | + | |
| - | + | ||
| - | {{::servo-modify-004.jpg?nolink&500|}} | + | |
| - | + | ||
| - | ==== step 5: remove the screw which holds the potentiometer in place ==== | + | |
| - | + | ||
| - | {{::servo-modify-005.jpg?nolink&500|}} | + | |
| - | + | ||
| - | ==== step 6: remove the metal gear ==== | + | |
| - | + | ||
| - | * the gear with the pin will come off together with the second gear shown on the piece of paper. | + | |
| - | + | ||
| - | {{:servo-modify-006.jpg?nolink&500|}} | + | |
| - | + | ||
| - | ==== step 7: pull the potentiometer out ==== | + | |
| - | + | ||
| - | * it should come out very easily, no force needed | + | |
| - | + | ||
| - | {{::servo-modify-007.jpg?nolink&500|}} | + | |
| - | + | ||
| - | ==== step 8: make a hole in the casing ==== | + | |
| - | + | ||
| - | * the hole should be big enough for the three potentiometer wires to pass comfortably when you close back the casing. | + | |
| - | + | ||
| - | {{::servo-modify-008.jpg?nolink&500|}} | + | |
| - | + | ||
| - | ==== step 9: remove the metal pin from the gear ==== | + | |
| - | + | ||
| - | * hold the pin with a pair of locking pliers. gently hit the top of the gear with a hammer to push the pin out. be careful not to damage the gear. | + | |
| - | + | ||
| - | * you can save the pin, in case you want to modify the servo back to normal | + | |
| - | + | ||

| - | + | ||
| - | {{::servo-modify-009b.jpg?nolink&500|}} | + | |
| - | + | ||
| - | ==== step 10: put the gears back in place ==== | + | |
| - | + | ||
| - | * make sure to put them back all the way so they can move | + | |
| - | + | ||
| - | {{::servo-modify-010.jpg?nolink&500|}} | + | |
| - | + | ||
| - | ==== step 11: put the bottom back leaving the potentiometer outside ==== | + | |
| - | + | ||
| - | {{:servo-modify-011.jpg?nolink&500|}} | + | |
| - | + | ||
| - | ==== step 12: put the top and the bottom of the casing back ==== | + | |
| - | + | ||
| - | * make sure the potentiometer's wires are not caught or pressed | + | |
| - | + | ||
| - | {{::servo-modify-012.jpg?nolink&500|}} | + | |
| - | + | ||
| - | ==== step 13: test the servo! ==== | + | |
| - | + | ||
| - | * connect the servo to a microcontroller and turn the potentiometer until you find a position where the servo doesn't turn. this will be you 90degrees. | + | |
| - | + | ||
| - | * any value bigger than 90 (but smaller than 180) will make the servo spin clockwise. accordingly, values between 0 and 89 will make it spin counterclockwise. the bigger the difference between 90 and the given value, the faster it will turn. | + | |
