Tag Archives: Always-On Laser Pointer

Mythos and Rini are very demanding when playing with laser pointer, we play with them almost every other night. For some odd reasons, we can’t find any “Always-On” laser pointer from pets or stationery stores. To conclude, we have the following issues with our existing laser pointer:

• AG13/LR44/357 watch batteries are way too expensive
• Watch battery does not last long enough
• Momentary switch makes my fingers become very tired and painful

Here is the mod.  This is extremely simple, anyone can do it in several hours. All you have to do is to carefully open the laser pointer by cutting on the right place with a hacksaw. Then, get rid of the momentary switch and replace it with a regular one.  You can use a  “project box”  (like the one I am using) which is ideal for this application.  Instead of using watch battery,  use 3 x 1.5v  AA battery with the battery holder. Solder and hot glue everything together, done!  It is bigger in size, but most importantly it solves the problems.

Mine is a low tech solution, but it works. If you have money and wanna go for high tech, you can consider buying an iPad and turn into a cat toy. Well, I think that’s one of the most expensive cat toy I have ever seen. Watch this video: iggy investigates an ipad on YouTube. One draw back though, the benefits of cardio exercises on chasing and running cannot be done on iPad. Love that video, the cat is so cute… wondering if I can do the same with my iPhone.
