Fidgety Fingers Etc

Guess who’s been at it again?
 
Actually Mrs W has been playing  experimenting with motors for a little while now, starting with her “Pull Back Buggy” with a home made pull-back motor, then a Lego pull-back motor, and then electric motors.  I won’t let her take the crane to pieces to use the motor in that, so the postman (and bank manager) has been busy.
 
From left to right is a six legged walker with remote control motor;  in the middle her second pull-back buggy complete with cannon and motor that gets ejected from the buggy if (when) it hits something;  and her latest creation some ‘Fidgety Fingers’ which can been seen fidgeting on YouTube.
 
Mrs W has made a video of all three in motion, and if I can get her to upload it to YouTube I will put a link in.
