Introduction: Digital Tachometer Modification

Adding a *constant on* feature.

I have wanted one of these for some time now but I need one that will stay on without holding down a button.  The ability to set the tool, leave it and say start or rev something then come back to it and know the max/min speeds is very useful for someone who works alone.  This was EASY, anyone can do it and in my opinion it makes for a much more useful tool.

I had to do a similar thing with a laser pointer. I used a clothespin. One could also wind a rubber band around the unit and place a small bit of plastic or other hard material over the switch to depress it. Not as sexy as adding another switch, but hey... It works as well.

Yes it would, a friend of mine bought the same unit after me and did just that.
