My cats are just plain old fashioned farm cats who only need a common
mouse to keep them entertained. The mice dont contain any motors,
transistors, capacitors, or batteries. Low tech, and much better for the
environment.
But these modern city cats have gone high tech. Some even have
smartphones, and have their own facebook pages. Thats the problem, They
expect their owners to provide electronic gadgets to entertain them,
then they dont even earn their "pay" to cover the cost of the batteries
for these gadgets, because they dont kill any mice.
I say, the solution is to just toss all the electronics and buy your cat
a plain old mouse. If the cat refuses to play with the mouse, trade that
citified cat for a plain old fashioned farm cat. Farm cats earn their
living, and they still have the balls to tackle the biggest mouse or
even a rat. Most of these modern citified cats dont even come with balls
anymore.
Geez, I just could not resist posting this reply! :)
On a serious note, I cant see the need for any transistors to operate a
small battery operated DC motor, unless it has some sort of speed
control, or reverses or something like that. I guess you will have to
determine what this toy does, besides just rotate. Like most cheap
modern stuff, they no longer label components. That fact alone, combined
with the small size of these parts, is one reason I prefer working on
old tube gear. Maybe someone else on here can point you in the right
direction regarding that transistor. I cant....
