Example 1 - Smaller Decoder approach

Kit: MX648; IceCube18X13X09-1W; LifeLink with SuperCap17000uF

Most Hornby Q1 models have an 8pin DCC socket in the loco, like this example. The approach in this example is relatively simple, with a great stay-alive.

Remove the 8pin DCC socket, as we want to place the IceCube speaker there instead.

The 17000uF SuperCap sits on one side, with the case protected with Kapton tape, and teh MX648 sound decoder sits on the opposite wall.

In this one we have also added a firebox glow LED and a cab light (SMD). The body just slides on after this, thouh it is quite tight on the width around the motor.

Example 2 - bigger decoder and speaker

Kit: MX645; Rail Exclusives Boomer 18x13x13-1W speaker; SuperCap17000uF

This approach is tighter than the above, but it can be made to go in - just! Unusually, the Q1 has its' retaining screw down the chimney.

In order to get the slightly bigger speaker in, we have to grind the screw mounts on the base where the 8pin DCC socket was attached.

Shown here are the eventual positions of the speaker and the SuperCap.

We begin the wiring up process, protecting items using Kapton tape as we go.

The MX645 hangs off the side, and (hopefully!) the body should just slide back on afterwards.
