Heljan OO 128 Parcels DPU - MS

Heljan OO DPU 128 Parcels with Zimo MS Sound

Kit: MS440D/C; IceCube28X18X08

A nice simple approach on Heljan's OO DPU here, using an MS sound decoder, decent speaker, and the standard 1000uF capacitor that comes with the MS440 for stay-alive.

Example 1

Example 1

There are no pads for a speaker on the model's PCB - just a little 2pin socket but no plug provided to go into it! So, we wire up 2 purple wires direct to the decoder for the speaker instead.

Example 1

Simply plug the decoder in and we can test motion and lighting.

Example 1 Example 1

A perfect space for an 8mm dual IceCube speaker is behind one of the cab walls, and our 1000uF capacitor fits easily at the opposite end. Secure with some BlackTack.

Example 1 Example 1

Tidy up the wiring and we're all done!
