In the past few weeks i have been experimenting with my solenoid: http://www.electromechanicsonline.com/product.asp?pid=24
12v (10% duty cycle)
I need this solenoid to kick a roughly ~250gram 75mm radius ball for 2 meters (without the ball slowing down)
Because it was rated to be 12v i first used it with a 12v ni-hm battery and activated the solenoid with a relay , with which i could shoot the ball 50cm (barely).
After a while i got tired of only getting a small kick like that, so i got busy experimenting,
first i tried it with 18 volt (one 12v and one 6v battery pack) i got bit better kick (60cm) with 24v(2 x 12v battery packs) i got ~70cm and with
36 volt (2 x 12v and 2 x 6v battery packs) got almost 1 meter,
i could go on and on adding battery cells but due to the weight issue i couldn't really make that work, so i am now thinking of a way to build
a step-up circiut to charge a capacitor and then use that to give the solenoid 300+ volts.
as i figure that voltage should be sufficient, so after i did some research i fount this circuit:http://www.flickr.com/photos/58860084@N03/5395710031/
(ac-to dc converter)
The 230v output (inverter) would go to the IN (ac to dc converter) and hopefully i will get enough power to charge the capacitor and then get
a better kick from the solenoid.
Does anyone know if this circuit would work? or are there any other alternatives to get a better kick from a solenoid?
Any advise is appreciated .
