Topic: Making my own solenoid (Read 1 time) previous topic - next topic


Thanks for the replies!

@ MonkeyKnight: That might work well! I'm going to give that a try during the day and let you know how well it works.

@ PeterH: The drops have to be fairly large, I already have a system for single drops. I have an Arduino set up with light, sound and vibration senors. Depending on the light generated from the action I am trying to capture the shutter is either left open in a dark room and the flashes are triggered via the sensors. If there is a lot of light I have an IR LED which triggers the shutter. In this particular case I am trying to get easy collisions. Here is a link:


@ Chagrin: Great idea but I would need the ball to go back almost instantly?

Thanks for the help! I am going to try out all these ideas during the course of the day and let you know how it goes!

Solenoids usually are electromagnets that are optimised for long travel distance.

If you can get a reasonably-sized relay you may be able to use it's mechanical movement.

Every automobile has several small plug-in relays, "headlight relays" etc.  They run on 12 VDC. Find a scrap yard. I would not recommend *Midnight Auto unless you are under the age of 12...

EDIT: * Sorry, dumb wise*** comment. "Midnight Auto", back in the 50's was stealing needed car parts from some other car, around Midnight. If you were caught but were underage, you didn't go to jail...   Sigh...

Thanks for the help! Luckily I managed to find a far larger syringe for the top, one that is used to medicate livestock, my device now works pretty well and using the Arduino I can now control drop collisions with less trouble! And avoided ordering a solenoid  ;)

@ terryking228: Thanks! I will defiantly have a look into that next time. I am not sure I understand what you mean about the age thing?

Thanks again!
