E11 Blaster pipe build with lights and sound

Recommended Posts

Next are the speakers. I'm using the 'kitsound mini portable speaker', it's a great small but very punchy little speaker. First if all I unscrewed the housing and removed the 'guts', this consisted of a audio Jack, circuit board and lithium rechargable battery. 
To get the speaker out involved a bit of hacking and cutting with a dremel, checked the fitment and the speaker is around a millimetre to big to fit, took it to the bench grinder to shave a bit off, hopefully the heat hasn't damaged the magnets inside, will find out in due course when I re-test the circuited823594e3466e7a919924a9fede334e.jpg49b60190af19f8946c3f929682dd4104.jpg3f9fe96b7aa3a3ccf9a615981d1269d6.jpge519d85a04fb9fdde239733b64e3a3d8.jpg80d18160ded4ee8eb4afc2d8624ffdde.jpg4c94da7c5ea1e31443d0ea1e932ce99a.jpgce252312cc00bfe83611af69326f8853.jpg67f4a050ae8d563b71e202016e321a93.jpg

Working on the grip and trigger assembly.
Drilled and carved out the retraining pins from both sides for a micro switch.d8d53108b0745421577b504236fbca33.jpgc40890473741ce4091b5d37da3742973.jpg82ad72f8e8e3ef02db10002e6c926b04.jpg2582623203c947cda88c4607f23abf64.jpg4046bb5b4342e7173afaac2b3a47933b.jpgf7575eea85bb8af8824c28818e905380.jpgfb9ee813bacc42f220bc3f06da1fe353.jpgdf8e4186a2c4fe1eaf348f7e17705974.jpg

More carving out for the trigger, fabricated a trigger from 6mm acrylic, pivots on a steel pin and tension created using a spring from a pen, engages with a micro switch (used on microwave doors), very happy with the result, the trigger makes a satisfying 'click' when it engages with the switchb14d5707f1b3826fa2d943bc248f8a25.jpgc94f019300888a9973a3ad56624dec9d.jpge4f0f5ece661af91ea0b9552df7c0b93.jpg12af1fe5383fd68c46bc7a8fee285670.jpg8c5a624d4902724857e4b6ec2896a128.jpgd902922851fe3ee5c69f7f16ca771c90.jpg

Cut out slots in the barrels for trigger mechanisms and wires to pass through and got grips fitted to the barrels, slowly starting to look more like 'space guns'102d9fe4593b8a93fb131a83cafae3b1.jpge650a192a0195191afefff7c53094b68.jpg

Hollowing out the magazine well for a battery compartment but disaster struck and it broke up

Thought to myself that the mag well is not that complicated a shape so went to work on fabricating one out of plasticard, also means I don't have to do more resin carving, whatever resin doopydoos use creates an ungodly amount of dust!

I am running the circuit off a 7.4v camera battery, they are ideal for this, also the chargers can be got at a reasonable price from eBay, got extra chargers as I chopped up some to use as 'carrier's' for the batteries 
I cut off the greeblies from the old mag wells to keep for the new ones9d28c64a6a315b013514fc003f3bdfff.jpg37efcc2b3159e7bbee736020bb443124.jpg6a19b11704bbfcef8db824f9b9c88c9d.jpg175cf64ca2e727d45654dfa58a81831c.jpg0a8682d013edc78bd136bd2fccf617de.jpg9f2c87cb73a50e321dddfffab4630ea2.jpg538ed38a65cf56b01148c41b2bf56314.jpgec2de48086275821ec4c4c290e8cfd38.jpg31fcd32a3c8726b28c5f37bc723afa4a.jpg

Reshaped the magazine to make it more accurate, drilled a divet in the end and glued a small plastic bead in to simulate a missing detail, engraved the 'off' sign and arrow.
Glued magazine to the barrel.a513fa08d6581db4f0e233dea20a5303.jpg1867680100efada20a60583c50b21811.jpg

Wired the RGB Led then arranged the three led regulators into a pyramid shape, superglue them together using the capacitors as anchor points and soldered all the connecting led and control cables, also arranged the speaker into this assembly using a strip of plasticard for the wires to pass through.
Immediately after the speaker I wired the micro controller (can't find pics)872cee5b672abe8d14b35bc9d5585c58.jpg9b29bd358affb8ed186e904e22ba52fb.jpgbcfb056a12f4ed0c341fbedd1324acba.jpg6966e9effbb9e32497ef5e58b946b055.jpg59acde327536b555f1b1bbb2b28988eb.jpg373c8341b23b1f067271d0da49cf020f.jpgde4e5b8f6da1cfc73499ec2aebab9ad9.jpg92a7c081f006bd126329ea62f47724bc.jpg9cb3dfad48bb9a9cd531019d718829ee.jpg

Fed all the cables from the scope, couter and switches through the body and out of the ejection port, also connected up the led and speaker cables to the micro controller and everthing from the controller also out of the ejection port, here the corresponding cables were soldered and heat shrunk to their counterparts.
I uploaded the micro controller with the code to 'run' everything.
All the joined cables are pushed into the body of the blaster and the bolt and spring slid back to hide them.
Next was inserting the 7.4v camera battery and turning on the circuit to make sure it worked, everything worked great!, happy daysf19536b70c646b974ddc7d0d779f4bae.jpg7826b15e18cb5de0ace3453ae513ff63.jpg71748dddc4b76a0a471f733614e12438.jpg6389f1095acd55ea6bdfd53c70aa0a90.jpg

t-track from 'Marv the Martian' fitted by cutting one end into a tapper, slowly heating the end with a heat gun and pushing it into the 11mm hole and holding it their until it goes hard again, then marking the other end with a pencil trimming and repeating.

ll the electronics are complete, the blaster has four controls/switches.

The first is located in the magazine release button, this turns everything on

The second is the trigger, this activates the super bright RGB led at the front and also sends a message to the mp3 player to activate the blaster sound. The ammo counter goes down as shots are fired until empty which activates 'out if ammo' sound file.

The third trigger located under the ammo counter reloads the blaster and activates reload sound and fills up the ammo counter.

Forth button located in the handle/grip retaining pin changes weapon between 3 modes, single fire, rapid fire and 'set for stun', the stun setting activates the blue led at the nozzle and corresponding sound file in the mp3 player.

Also the 3 settingss will make the scope light behave differently to indicate what mode your in, led on is single fire, flashing fast is rapid fire and flashing slow is set for stun

Weathering has been completed on all three blasters

Here are some of the acrylic colours I like to use for weathering blasters

Raven black, burnt umber, bonfire Orange, boltgun metal and silver, they are very tight quality modelling acrylics and contain a high percentage of pigment.

The writing on the m38 scope is an easy one, regular white crayon rubbed into the indentations and the excces cleared away rubbing a finger over ite5f514b0d1c8fc6f2174a665b0ae4baa.jpgb378383a5bb1c0e2408b35fb19e14801.jpg703dab65c84f48b41dd46adb26ba2616.jpg

Took a few pictures earlier of the weathering, used the deac sterling for reference but slightly toned down.
The paint shows up more on camera, it's actually more subtle than shown.81ab48404641a7d0b8d7eee6badc0943.jpg17217a5b9cea5404dc6f1ab867a22817.jpg79728bf7876920a8f52fae53ce6cc469.jpgd94127bb23889b0edbac350e7c9e3ea0.jpgb790670d30a82e12d3dd0e8f5046f6a7.jpga5035091d524a68af0fb2714ba23314e.jpgd75b6a13a4604f461d36fe9b0c1b2b13.jpgfa3cb2e487a0ca94c8657e3d5897936e.jpgbb36245dee35ffa04985d960bb2270a8.jpgc4c44078f87abfa3b52875960877ba2a.jpg96e964491f313b01b44a1493b9afaf38.jpg43e9d6a69f49b8d49d3f8bb5280dfa6d.jpge363f34eb84e68dc5ab7d6853184b828.jpgb994ec4ddfb62f026c51309b666af95f.jpgf1128a696d7253c62231948012e6bc89.jpg80caef642b9e14e606990a9649daf00d.jpgb9ec105ed828fcb8068552941dcaa423.jpg41df5d67b9afbaefc7ea2075599fc515.jpgdee44a02a68e44a3efa55787baf65169.jpg5ba14632919c1dba40f034be0082e001.jpg3c01610679d86835cdbbadd24465ff92.jpg889fa6423c213c09526979311ca8433f.jpg

Wow. Nice work. I’m only viewing on my phone at the moment but, from what I can see, you’ve finished them really nicely. :-)
Impressive amount of electronics squeezed in there, too.
Great job. :-)
