Once I knew that I could knock the target over with my little Airsoft gun I had to find out if I could pop it back up. I sent off for five of these little 12V solenoids. (Link to allelectronics.com).
They arrived and I attached one to my prototype target, that had now lost some metal of the bottom and gained some weights instead, This helped me balance the target better.
Here is a video of the solenoid test.
At this point I was just connecting the solenoid terminals to a 12V battery pack I had.
The bracket for the Solenoid was quite complicated as I had to add an extra flap to stop the solenoid core from falling out as it was not retained by the solenoid itself:
This would turn into a much more simple design by the end of the target creation so I won't talk about creating the bracket now.
It was also time to redesign the target as it was quite over worked, but that's how you learn lessons I guess.
I changed the core of the target from the 'U' shaped assembly to a single block of wood:
With a hole in the corner to hold the hinge pin:
And sanded so as to clear the target as it moves:
The targets are cut from the aluminum sheeting I had:
And the hinge holes Drilled in the hinge flaps:
The target is attached to the holder with a short length of wire coat hanger wire:
(Bend one side of the wire before you put it through the hinge holes and the other end once it's through).
Lastly for weight and as a handy way of balancing the target I put a small bolt through the bottom corner and used washers and nuts to get the balance just right (Sorry this picture isn't the best I hope you get the idea).
Next Time, the new solenoid design...
