Frequency Counter

Picture 1. Frequency Counter by Bp. Budi Kencana/ PT. PACK

Sebenarnya PIC programmer tersebut saya gunakan untuk hobi saja, saya sedang membuat aplikasi frequncy counter dimana dengan menggunakan PIC rangkaian FC menjadi lebih simpel dibanding dengan IC TTL.

Sumber applikasi FC saya dapat dari.

DC Motor Shaft Offset Modification

The following instructions detail how to modify DC Motor Shaft Offset
(Item No. # MT020210) from a torquey slow 120:1 ratio to a speedy 14:1 ratio.
A similar modification can also work with the DC Motor Shaft (Item No. # MT020210)
but it’s a bit more involved due to the crown gear used.

1. Take out the two screws and open up the gear casing, you may need to use a flat head screwdriver to pry apart the two half’s.
2. Remove the gear with the slip clutch (the output gear) as well as
the gear driving the output gear.
3. Remove all of the remaining gears except the one on the motor output.
4. Of the two smaller white gears you want to save the one with the bigger center gear, this one meshes better with the output gear (the one with the slip clutch).
5. The problem with simply removing gears is that the output shaft will be countersunk in the gear casing. To fix this problem you will need a spacer of some sort; one of
the unused gears works well. I use the green gear, but the other spare white gear could also be used. Be sure to clip away some of the edge of this spacer gear so that it doesn’t interfere with the gear works.

6. Slide the spacer onto the middle shaft.
7. Place the white gear we saved earlier (the one with the larger center gear) on
top of the spacer. You will most likely have to slide the small pinion gear on the motor shaft up a bit to get the pinion to mesh with the white gear. Slide the pinion so that the two gears are level. If you go too far he gear on the motor output won’t have enough grip.
8. Almost done, just add the final output gear (again the one with the slip clutch), snap on the motor casing and put in the two screws, that’s it. Done!

Modification Servo to Continious Rotation

If you need servo for continious rotation, you must un-assembly the case first,
cut the pin stopper at main gear and de-soldering motor connection behind PCB Board,
and the last, desoldering potentiometer, replace existing potentiometer with
2 pcs Resistor (about 2.2K Ohm) as paralel connection.
Assembly again your servo motor, servo ready to continious moving now.
