Kit: Zimo MS490; SugarCube6 speaker; LifeLink + 5x 470uF Tall Tantalums
Time for a revamped guide for the OO Steam Sentinel, using one of the latest MS490 decoders. It still needs to be hard-wired to
make the best use of space, so we disassemble and connect orange/grey decoder wires direct to the motor, and replace the pickup
wires with some nicer red and black wires.
With unwanted lighting wires removed, we wire up the MS490, SugarCube6 speaker and an array of 5x 470uF Tall Tantalums for
stay-alive via a LifeLink. On the MS490 we could connect up to 1000uF for stay-alive directly, but if we want to go higher,
then the LifeLink is required. This little model needs all the help it can get!
The Tantlaums are connected in parallel, then covered in black electrical tape to insulate and disguise, and the speaker
enclosure it painted black to hide it too.
Using BlackTack, the Tantalums are stuck into the roof first, the decoder on top, and speaker forward of that, all rear of the
open windows so you cannot easily see any of the kit.
