Cylon Rifle with Lights and Sound

[welshchris77]

Finally made a start on the Cylon rifle kit I have had lying in a box for the last year!
Big thanks to Brian for the kit

First thing was to trim the parts to get them to meet up a little better.
Masking tape and a pencil is good to use as a guide on dark plastic.

Test fitting parts with tape and glued the stock together

[welshchris77]

Using a Arduino nano, mp3 player, amplifier chip, 1w LED's and drivers for the circuit run off a 7.4v camera battery.
Prototyped the circuit on breadboards and have the code working.
Have since increased the LED's to x6 blue for the barrel (one for each slot) with a white LED for the muzzle.
When the trigger is pressed the LED's will flash blue in sequence along the barrel ending in a white flash at the muzzle and Cylon rifle sound!

Rather than wrapping the acrylic tube in electrical tape I decided to go for a more 'sanitized look' so I went about making a barrel shroud that would emulate the 'look' of the original but also be easier to remove for maintenance if need be.

To fabricate this piece I cut up a black storage container, heated it and shaped it around a piece of pipe then then cut slots. I glued some Velcro to hold it onto the main body of the rifle using E6000.

I build an internal structure from abs and plasticard, I used Velcro to hold the two pieces of the main body together.

The LED's will fit inside a smaller acrylic tube, I bored a hole using a spade bit in the cast resin muzzle piece to accept the tube then fabricated two clear acrylic washers to keep both tubes in place

[welshchris77]

Cut a section out of the larger tube to accommodate and access electronics, I also fabricated some abs brackets to hold the tubes in place

[welshchris77]

Mounted the LED's and drivers onto a aluminium rod and soldered the wires

[welshchris77]

Using jst connectors for the LED sub assembly for future servicing.
I trimmed the clips on the connectors to make them slightly easier to separate.
These are great little plugs!

[welshchris77]

Cut a recess and added support structures for the speakers, wired speakers to the amplification chip, added jst plugs and installed speaker assembly

[welshchris77]

Internal support structure for the stock made from plasticard with supports for the battery.
The stock can slide out of the main body to access the battery

[welshchris77]

Battery contacts made from copper wire, contact ends flattened out with a hammer and holes drilled to allow for soldering.
Wires soldered, heat shrunk and jst connector added

[welshchris77]

Mp3 player soldered and installed

Arduino nano soldered and installed, code uploaded, love this little microprocessor, very compact and easy to use.

Trigger button also fitted and on/off micro switch
