Step 9: Blast Away!

If all went well, you can begin felling stormtroopers.

Here is a video of the blaster operating in a well lit room.

<p>So, did you use just 4 AAA batteries = 6v supply or one 9v and 2 AA's with two seperate power supplies? Do the schematics reflect actual resistors and caps used on Your build? The directions show several so I am confused how it actually works. Please clarify. </p>
I've been staring at these pictures for a couple days trying to make sense of it, but I've got no experience with electronics and timers, so I'm probably going to have to avoid circuits entirely and stick to push-button activation. Pulling the trigger would push the switch that completes the circuit, and it would remain on for as long as the trigger is held.
can someone tell me how much this is or i will eat a cat
how much did it cost to make this ?
My husband fell in love with this as soon as he saw it! Wonderful work! <br> <br>Too bad neither of us have an electronic know how. Anyone willing to make 2 for us? I can do everything after step 7, just need the lights and sound.
This is a sick star wars gun. I wish I could make one. <br>
Hey, <br> <br>Nice cirquit, but i need 2 of these and one 5 led chaser, can this be powered by one or 2 USB Ports? <br>And if so, how do i do it?
wow it looks just like the original prop:D
I AM THE HAPPIEST GUY IN ZEEEEEE WORLD!!!!!! yeaaaaaaaaaaa@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@!!!! =^-^=MEW MEW? fuck yea man i LOVE THIS WEBSITE!^0^ gREETINgS 4RM THE PLANET eARtH
cool project
Can I please have a parts list?
It would also be a nice idea to use the blue LEDs, instead of a chaser, to use them as a &quot;round counter&quot; to then just press a button to &quot;reset&quot; it. It's just something that came into mind while seeing how it works. Although it's really cool.
Thank you so much for the info on how you did your lighting effect -- I've been tinkering with a very similar idea (also tired of prop guns that make a wimpy sound and blink a single LED.) Nice to see the idea of combining a super-bright and a laser works so well. Can you share some info on the laser module and why you chose that particular one?<br><br>Oh, and there's enough on this page -- the assembly of the housing -- to warrant a full instructable on its own. You &quot;expoxied aluminum skin to the cone?&quot; Finding out more about how you did that, alone, would be worth the price of admission.<br><br>(I know...whine whine whine, more more more! :) )
how could i adjust this so that it worked like an republic blaster rifle?
cooool i want one
Very nice, but one thing I can't figure out is how you get the sound effect to play whenever you trigger it. I have the radio shack recordable module, but I can't figure out how to set it up so it will trigger when the power is switched on by the switch/trigger.
well, I honestly don't remember. But pin 3 is the output of the 555, so that should be wired to the base of the transistor. The collector is the positive, and the emitter is the negative side of the transistor, which you will wire up as the &quot;switch&quot; to activate the sound module. Sorry, I dont remember more specifics.<br><br>As far as making the sound play, mine just worked when triggered by the transistor. Maybe try removing the diode. Someone told me that I didnt realy need to use them. Although mine didn't work without them. And double-check the diode polarity.
Thanks to that help, I was able to get the 555timer chip circuit and the sound module to work perfectly. Again amazing job on the blaster.
the 555 one-shot triggers a transistor, which it wired to the &quot;play button&quot; on the sound module. pulling the trigger sets offf the 555 which turns on the transistors fro the various effects, one of which is the sound.
thank you for your reply, but how are the npn transistors (and the diodes) wired with the 555 one-shot? I'm having trouble looking at the images you have of the npn sequence to make out details on how it's wired. Is there a schematic you made?
About how much did it cost?
could you post a video of you using
Is there a way to create it without the sound?
Dont add the speaker... Remove it
Instead of using LEDs(light emitting diodes) Use a 5mW red Laser(light amplification by stimulating emission of radiation). It will go way farther<br />
If you look closely, you will see that I used both LED's and a laser.<br />
Pretty cool
wow great build 10/10! An other idea is if u used a 20-50mw green laser diode to see the actual laser beam <br />
Goodworkkeepitup.<br />
10 outta 10, good job dude, totally awesome.
&nbsp;I agree. totally awesome
Great project!!! I'd like to see about doing it myself, so I'm trying to lay out the entire circuit for all 3 functional blocks. I'm curious as to the final portion of the circuit, specifically the 3 chained NPNs. Can you post the outputs? Thanks.
I'm going to (well, at least try to) make the "clip" a battery pack with 2 contacts inside the gun so if "Luke" gets out of ammo (flat battery) he can reload, or just reload for the fun of it :)
does it actually shoot a laser ball sort of thing or is it a beam? that is really cool though.
iMac! W00t!!!
Very nice idea, well done, great clear instructable !
Awesome! I will try to make one!
Very nice!<br/><br/>I have a suggestion (I do not know the technical feasibility) you could put something that throws up a powder (flour, talcum powder) or smoke.<br/><br/>When it was launched the laser would appear as if the air like the films (because the light can only be seen when enter into contact with something). <br/><br/>What you think about it?<br/>=D<br/>
Awesome project! Congratulations on a well made blaster! What's up with the blue chaser though? Sometimes it seems to trigger much more chaotically than just the chase, then it's back to the regular dandy chase. Could it be if you trigger it again within the 1 second period?
Thanks, Yeah, I don't really know what's going on there. I think that the 4017 chip is really sensitive to "noise" or something. I couldn't solve it. Cheers, steve
Yupp, I have noticed it myself a few times. Have you found it to be related to multiple "shots" within a second, or does it happen if you wait a second or two between each shots? It would perhaps be an idea to bake it all onto one Arduino or PIC. :-)
No, its not multiple shots with a second, the thing is just skittish. Yes, this level of complexity would definitely be easier with a microcontroller. But the whole thing was an ongoing electronics learning experience for me.
And it worked out beautifully. Well done!!
AWESOME,question though: can u make it without the sound or without the chaser leds?
To answer Renagade, yes. The sound and chaser LEDS are an added effect for more fun and entertainment. If you don't have the parts, are to lazy to do it (like me), or feel those effects will cost to much on your budget, you can successfully build the gun with out the chaser LEDS and the sound, but you may need to take note of how to steer around those parts in the intractable without getting confused. If you wish to make the gun and use the chaser LEDS and sound, the parts are easily found at local electronic stores and online. Hope this helped! :)
what are all the parts for this instructable? (like i asked before) i want to get everything at once
Renegade, I don't really have a parts list put together, sorry. You just sort of have to figure it out as you go. Not Ideal, I know.
