From my experience &amp; from forum surfing, I can confidently say that your pinky finger will always be weaker than the others.  I have tried the following techniques and think that they can be used to help bridge the gap for you (aside from unfocused tapping):


Tap softer with the other fingers and tap harder with the pinky finger, slowly and cleanly.  Build up speed keeping the sound clean.
Use hand / finger grips to exercise the fingers, focusing on the pinky.  (Gripmaster, Planet Waves, Xtensor, etc.)
Use finger weights.


Place weights on pinky to make it work harder, which will in turn build strength.  Start off light, slow, and clean -- gradually increasing speed.  After a week or so, increase weight and start back slow.  You can alternate between increasing speed and or increasing weight, depending on what you want to train.


If I were you, I would invest in the finger weights.  I have found them very helpful.  You actually feel faster and stronger after playing with them on and then removing them and playing normally.

Note: I do not consider myself to be an expert guitar player.

Building hand strength for when tapping on the guitar
I need to connect my Samsung s1 cellphone to my home's lights when I am away. I realised that I can use my cellphones' vibrator signal when I call my "Home" cellphone number. I know that the mentioned signal is less than 2 volts (I don't know exactly!) and to operate such a method, I need a relay to convert this low voltage into regular home electricity voltage (240V).
I tried to find a proper relay, but all what I find is that 5VDC relay from sparkfun:

Would you advise me if that would work fine with my requirement or not?
Is there any easiest way to do that?
What is your advice please?

NOTE: I have a slight knowledge in electronics!
