[...] One trick that I put together (on paper) requires that the lid of a wooden box open by its self (remote control)
The lid of the box is made of thin ply wood and is only 12"x12" inches.
My problem is opening the box. Should I use a solenoid (push) or a servo motor? I have room in the box to put either along with up to 8 D cell batteries to operate it. The lid will not be held open any longer then 5 to 10 seconds at any given time.
Something you'll have to define:
- How fast should the lid open?
- How high should it open?
- Should it close again by remote control?
- What about the noise/sound coming from the mechanism?
Answering the above will help us help you. I have several ideas, but finding the best solution really needs all the parameters to be known.
A wireless doorbell could possibly be a problem, unless it's digitally coded, as noise signals might set it off.
If this is for something that you want to manufacture for sale, you should have a keen eye on possible error modes, to avoid getting angry customers
