As some of you may know, some time ago I built Amati's model of a Greek bireme. Although it's a 'Static' model, I opted to make the oars actually operate. I used a couple of radio control servos to raise and lower them ant to sweep them back and forwards.
I built a simple electronics circuit to drive the servos. Operation is limited to a simple straight ahead rowing action. However, that set me thinking about ways to have full control over the oars. I had no thoughts of actually building an RC oar powered model, but I did consider various ways in which it could be done.
Some time later Jim (bensid54 on the ModelShipBuider site) contacted me to say he was thinking of building an RC version of the bireme. That started me off again thinking of how to control the oars. I'd recently fitted a microprocessor in my model of Vanguard to flicker the lights so I decided to try using one to drive the oars.
Jim recently posted a Video of his system on YouTube which I thought was a great idea.
He's used some advanced feature of his radio system to control two modified servos so he has variable speed control of each set of oars.
I had to make do with my son's basic 2 channel radio which is specifically designed for use with a model car, (trigger for throttle, steering wheel on the side) but the microprocessor does allow me to get round those limitations.
Anyway, I've copied Jims's idea and posted a video on YouTube:
As you can see, I've raided the Technics Lego drawer again. It's great for working mechanisms, but all the Technics parts have holes in them so I don't think there's much chance of it actually floating!
came across your post with the video today first time....
well made technique for actuating the oars, congrats, it really works !!
