....this doesn't look a mechanically simple project with the chaotic
movement of the pendulum.....perhaps there is some way to give the 
pendulum a jolt whenever the maximum deflection has been 'too low'
for 'a while', but complicated by need to be 'in phase and at right time'
......would very much like to hear of any success.....
