( How The Idea Was Born - Micropolis Links - Adding an Arduino - Power Connections )
This is a collaborative workspace! We've developed an update to the TwinLUG Micropolis building plate standard, which will allow easy routing of a power drop cable under the roads and modules, so we can easily power lights in the buildings on the modules.
We aren't suggesting that everyone retrofit their existing bases, because we could cluster the electrified modules adjacent to each other. But, having a few extra buildings that can pass power below would let we Micropolis2 folks spread the light out, to light other nearby modules in their glow. The more folks how adapt their MoC bases to Micropolis2, the better our chances of lighting many MoCs when we get to a conference!
My 2023 project is building a Dag Diamond, with a couple adapted quarter-blocks.
I'd like to see a couple new pages, for Micropolis trains, and for Micropolis water modules (rivers and coasts).
Bill Ward has made a beautiful Metro Train MOC, using the 1x2 grill tiles for the track.
I started thinking about making freight trains, but didn't do much with it, because I didn't have minifig skate wheels...
At Bricks by the Bay 2018, I finally got a chance to try my ideas. I hacked with grill tiles as tracks.
Spring of 2019, I bought 120 minifig skate wheels, and started making freight cars in earnest!
At Bricks Cascade 2020, Patrick (PortLUG member) had a microscale train display with the larger train layouts!
- I was inspired by his piggy-back flatcars, his yard tracks, and the nearby "industry" buildings.
Spring of 2020, I've really dived in, and am getting ready for my next big Bricklink order!
- I'm working on a 2-track Main Line border for Micropolis layouts
- I've built a 2-track curve, to be the corner on that Micropolis layout
- This turned into 6 more Bricklink orders, 16 modules covering 10+ feet of table edge, and 23 feet of rolling stock!
There is now a page for Microscale Trains, to put a railroad edge around your Micropolis city!

By adding eight 1x4 arch bricks (blue in the left-side image above), this provides the power cable routing path for any plan. (I considered a 1x3 arch, but that would make it tougher to get a model to settle above the power cable. 1x4 gives more latitude!)
The open-bottom arches makes it easy to move modules around, and drop them anywhere, and allow power to pass easily.
Each corner uses a 1x3 plate (light blue), a 2x2 "L" (pink), and a 2x2 brick (red) to secure them (one 2x2 is shifted, to see the plates). Under each 1x4 technic beam (red), there is a 1x6 plate (yellow). The arches have anchors on each side, for a sturdy base. The colors used here are only to help the parts stand out for identification in this discussion. Feel free to pick your own colors, because these will be UNDER your MoC, and will rarely be seen. I just kept consistent colors in order to describe the parts and illustrate their location. :-)
** Note: It's easier to use two 1x1 bricks and a 1x2 Technic brick at the center of each side, rather than a 1x4 Technic brick. One peg is enough to join the modules. But, at the few Micropolis layouts, the tables were flat enough that we didn't peg many of the modules.
2020-07-17 Someone suggested that we add a MILS-like ID Code (in the Micropolis Panel at Bricks by the Bay 2020) to the Micropolis2 train modules, so I propose replacing the 2x2 brick on the corner with a 2x2 "L" brick so you can add your three-color 1x1 (square-or-round) plates. Bill Ward pointed out that we all probably know who built most models, so maybe you only need to mark two opposite corners of your block modules.
You will probably need some "cribbing" brick+plate combinations under the plates where they join, to give them stability while you are building your model. But, after your smaller models are built, I think you will be able to remove the extra bricks underneath. Some larger models may want to keep some bracing piers. (What do you think?)
Using larger plates on top of the base above will reduce the amount of extra bricks needed for support under the top plates. (Again, colors are picked just to make it easy to spot the plates and tiles for this discussion.) Leave a hole in the baseplates to drop your power cable. I'm suggesting a 2x2 opening.
(I'm still looking for a stable, polarized, easy-to-plug connector pair to use for power distribution, but I am leaning towards Molex parts 03-06-1022 and -2024.)
Of course, extra border roads will also need to have arch bricks. And any medians, waterways, etc. will need arches as well. These connections are where you will find Technic pegs to be useful. A sturdy border will half keep the city together.
Power for the models will come from a distribution cable, laid out on the table, and then the modules would be connected, and sit on top of the cable. The distribution cable will have connectors for between 4 to 16 modules.
Power will come from a USB-based battery pack for small displays. For larger planned layout, and multi-day events, a USB power pack could be used.
The image to the right shows a battery pack and power cable in red, with eight modules shown in blue.
A power module will be built into a double module, capable of driving 4 power cables. |
