Hello All, So I've finally got my act together and started building my layout however due to space the Lego 12v points are my only option as the 9V/PF switches take to much room. However an electronic pair will set you back around £90-£110 with all the switch boxes etc. So my challenge was can I do it cheaper? The answer was Yes. My first design (first image) was to use the Lego servo motor as it turns 90 degrees however these are around £20, then you'd need a Sbrick or another way to control it. It works but it looks bulky. So as I use Ncontrol from 4D Brix, I like the interface, click options and Tom is really helpful. So after a quick chat he wrote some code for me to limit the movement to 90 degrees and I purchased a Monorail Switch. It is very simple, looks neat and above all works. You have to purchase the quad motor control module but the beauty is that this will do four switches. So if you have 4 switches you save £30 on the second pair. So your first pair will cost you £80 but the next pair will only cost £50. This is the cost Lego 12 Volt Points Pair @ £100 My Second Design @ £80 Lego 12volt points not motor > £20 2x 4D Brix Motors > £25 4x 1 Meter Cables > £5 4D Brix Quad Control > £30 The only downside is you lose the turning symbol but I can see that in the software so it doesn't bother me.
