1/1000 アンドロメダ ムービーエフェクトVer. プラモデ 1/1000 ANDROMEDA 2202 (SPACE BATTLESHIP YAMATO 2202)








Modelled by TOMO

LEDs are added in the beam cannon with rotation to emulate the firing of the beam cannons. I am not sure if the extra firing sound effects are incorporated into the LED unit , or TOMO has designed a circuit to play the new sound, or just play the sound effects with a music player in the background , not shown from the video.

As for the rotation of the cannons and the extra LEDs at the display stand base, I don't know if an extra power supply (batteries) are needed, I am not sure if the extra power can be drawn from the existing batteries in the display stand base.

How did TOMO run the wires to the LEDs at the end of those antennae??

Excellent work!



Another modeller (DOROBOU HIGE) did the same thing : LEDs at antennae and , rotating cannons.



































These is the circuit diagram for motor control.

TA7291P is a motor drive IC chip made by Toshiba

datasheet:

PIC 12F675 is a CMOS Flash-based 8-bit microcontroller  made by MIcrochips


This is the datasheet for the microcontroller for those who are interested :

http://ww1.microchip.com/downloads/en/DeviceDoc/41190G.pdf



This circuit is for controlling the movements of the beam cannons and other added LEDs (navigation lights , ship command tower , etc)


The brain for this is another Flash-based Microcontroller PIC16F88 made by Microships.

This is the datasheet:

http://ww1.microchip.com/downloads/en/DeviceDoc/30487D.pdf

TPs603 is a photo-transistor receiver, basically , it detects infra-red signal from remote , the microcontroler receive the signal and controls various LEDs and motor movements.

RB0 - RB3 from PIC16F88 drive the LEDs ( the triangle-with-a-bar symbols with arrows)/





This circuit controls the LEDs at the display base.

Again, using the TPS603 opto-transistor receiver , when it receives infrared, it turns on another transistor (NPN type) 2SC2120 which provide a high current to activate the relay through a diode/coil IS1588 (a relay is a an electical operated switch, opening/closing controlled by the presence / absence of electrical current through the diode/coil , the IS1588 in this case).

When the relay is closed , it closes the circuit  and  electrical current flows  , and the LED turns on.....but why used a relay to turn on the LED? A simpler circuit can do!?

This is how you add LEDs to those antennae.
As I suspected, you have to make grooves in the plastic to run the wire to the LEDs, then you seal the grooves and cover the wire with putty.



















DOROBOHIGE replaced the wings at the top of the command tower with clear plastic so that LEDs can shine through giving a better lighting effect.















This is the motor control circuit with microcontrollers PIC12F765 and motor driver TA7291P.











Surface mount LEDs, usually red /green ones are cheaper.







This is one of the ways to spray paint panel lines.

Spray the body with black , then  spray the black with gray lightly, the gray doesn't cover the black in the panel lines , so the black panel lines show.






















































This controls various LEDs on the ship.













Excellent work!



One thing about this model, Bandai somehow decided that the ship should NOT be detached from the base, the wire ribbon runs from the control unit (inside the base to the ship's bottom (near the opening for the fighter planes) through the shaft of the stand to the LED unit inside the ship. The ship can not be removed from the stand unless you cut the ribbon cable and add miniature connectors to re-connect the wire ribbon. This is a dumb move from Bandai since the old 1/700 version of Andromeda, the model ship can be detached  from the base even with lights inside the ship (there are electrical contacts at where the ship make connection to the display stand).
