Hi all.
Now I may be about to ask what might turn out to be a complected if not a somewhat stupid question as I have found when trying to work it out.
I am looking at creating a pendulum the ones used in clock's,one with a round bob and a long rod.The thing is I would like the pendulum to be made from LED's that would fixed to a pannel lighting up showing a pendulums swing.
The rod length would be around 900mm width around 20mm the bob around 100mm in diameter all made in 3mm LED's.
The hard bit is the pendulums motion.I don't want the pendulum to travel far in each direction maybe no more that 50mm from center each way.I am looking for a smooth transition from left to right passing the center bottom as though the pendulum is swinging smoothly.
I drew this up in Corel draw and used a facility that allowed me to move the pendulum on screen with the center of rotation at the very top of the rod as it would be in real life.What I found was it is very difficult to come up with the LED position that would make the pendulum motion look smooth as the LED'S light up, I had a stepping effect and not linier or too big of a gap between the LED's.
I may have over complicated the explanation but can anyone give any thought whether this task is possible and if so what IC's would be useful.I realize that the amount of LED's that may be required will be quite a lot.
At the moment it's just a project for a bit of fun but if it's doable then I will use it.
Regards Mark
