Codyhtml Posted June 8, 2005 Report Share Posted June 8, 2005 I want to make a target for my pellet Gun that will light a led to show what area of the targer was hit. I thought i could just use lke a 555 or 558 as monstablemultivibrators but i don't know what kind of switch i could use to tigger it. i would need a some kind of materal that could have the pellet penetrate it but just barely. then that shock could be used to push a push button? I can't use metal because of recoshey and stuff and like partical board or wafer wood or ply wood is to hard.so i can do the electrical part i think mabe this should have been posted in mechanical constructins?oh well it also needs to be a common material ps it dosent have to stop the bullet but it might be nice if it would because it would be safer it wouldent have a posibility of flying off somewhere Quote Link to comment Share on other sites More sharing options...
ante Posted June 8, 2005 Report Share Posted June 8, 2005 Hi Cody,Maybe you could make some sheet metal rings inside each other mounted on hinges, below the hinges a small switch connected to a timed latch. The contraption mounted inside a tube to catch the ricochets and fragments. Way out, isn’t it? 8) Quote Link to comment Share on other sites More sharing options...
Guest Alun Posted June 8, 2005 Report Share Posted June 8, 2005 An array of piezo transducers placed under the target might work. Quote Link to comment Share on other sites More sharing options...

ante Posted June 9, 2005 Report Share Posted June 9, 2005 Hi Cody,Any questions on this? ;D ;D ;D Quote Link to comment Share on other sites More sharing options...
Codyhtml Posted June 10, 2005 Author Report Share Posted June 10, 2005 so like the areas in black circles are they the places where you shoot at? and the area in red circle it the the LEDs and stuff? Quote Link to comment Share on other sites More sharing options...
ante Posted June 10, 2005 Report Share Posted June 10, 2005 Hi Cody,Ok, the only”CAD” program I have installed at the moment is paint! The left part of the picture is a front view of the target and the right is a side view. The black things that you have circled are supposed to be returning springs and the green below are small switches. The black dots symbolises the hinges! Does this help any or just make it worse? ;D Quote Link to comment Share on other sites More sharing options...
Codyhtml Posted June 11, 2005 Author Report Share Posted June 11, 2005 thanks it helps me i get it now so you shoot at the top part and it makes the part hit the push button switches and trigger the monostable ok i get it now that helps (it didn't make it worse ;D) Quote Link to comment Share on other sites More sharing options...
Codyhtml Posted June 11, 2005 Author Report Share Posted June 11, 2005 or wait do you shoot at the bottom part any way it helps Quote Link to comment Share on other sites More sharing options...
Sukhbinder Posted December 5, 2005 Report Share Posted December 5, 2005 Hi guys, i have an idea which me seema bit off to u. the concentric ring design is very good. What if the rings can be printed on a plastic film like PET. I got this idea from the way the contacts are made these days in membrane type keyboards. they use two printed plastic sheets with a spacer sheet in between. I have an vacuum deposition unit at my university, where i deposit aluminium contacts for my devices. A better alternate to this is to use commercially available ITO (indium tin oxide) coated PET sheets. can easily pattern the using PVC tape as mask and common chemicals. the PET is quite strong and the ITO coating is conductive in nature. i hope i'm not being to scientific. :D Quote Link to comment Share on other sites More sharing options...
ZomBiE Posted January 12, 2006 Report Share Posted January 12, 2006 We gone crazy and used a 21" sony trinitron monitor with touchscreen and my friend wrote the software ;D Quote Link to comment Share on other sites More sharing options...
eurobuskers Posted May 2, 2006 Report Share Posted May 2, 2006 maybe 3 metal detector ccts with the coils behind each ring? ;D Quote Link to comment Share on other sites More sharing options...
