Now the Greensavers are implanted, and receiver, sound module (USM-RC2), sound module extension (EXM-2) are in place and provisionally wired (I love wire entanglement
). Together with the power compartment on the other side (relays, amplifier and dc-dc-converter 24/5 volts) and the esc in the middle all electrical components are in place. The speakers are also provisionally and will be replaced by an individual made loudspeaker box with a dual coil speaker to fit both channels in one chassis. To control the gun elevation I didn't choose an expensive esc, because an electronic switch combined with 2 simple relays gives a fine double-throw switch to alter the direction of rotation by RC:
At the moment there are the following sounds implanted:
running (two gears)
motor turn off
gunshot with falling cartouche
linear track link squealing (is this the correct expression?)
curve track link squealing (depending on driving turns)
some commands as "Feindflugzeug gesichtet!" (enemy plane sighted); selectable by RC
30 songs and streams in the built-in player; selectable by RC, overall about 2 hours of music
5 occasional sounds, repeating in sections from 30 to 999 seconds
and one noise each for side moving and elevating the gun. I know this is not correct, and I consider if this may be nice or not.
In this state the tank is even ready to run (for testing), but there is still some more wiring to do: machine gun LED, convoy light and -last but not least- the Pololu! It will act 2 figures (commander, loader) with moving upper body, head and arm by servo.
By cessation of the voluminous 250 watts car hifi output stage (exchanged for Thomas Benedinis small 2 x 60 watts amplifier), the 12 volts auxiliary voltage and the powerful dc-dc-converter 24/12 volts together with the small Greensavers there is unfamiliarly large space in this tank!
