This is how the six displays will fit inside the pillars: To be continued...

The plan is to replace Kato's 23-437 OIOI building 😢 because at that location I need two corners and Kato's large buildings are too ... large. I googled around and decided to model two buildings after 1. MODI in Shibuya 渋谷モディ(because I like the modern design and the giant screen) and 2. Takashimaya Nihombashi Store 高島屋日本橋店 (because of the red awnings). At the end of last year, I took dozen of photos on location and built rough paper mockups to check if I was getting used to these two buildings on the layout. I am happy with the result, and a couple of weeks ago I started the 3D design of the MODI building. As usual, I am using Autodesk Fusion 360 as I have a free non-commercial license. I plan to 3D print it in several parts. That's the lobby: And the top floors: I am also experimenting with the giant screen. I can fit a 2.2" TFT LCD panel connected to a Raspberry Pi Zero W. The prototype display is curved, though, and I am also looking for an AMOLED display that I could bend. Unfortunately so far I have not found any of the right size.
To be continued... The spectacle shop, step by step construction Lighting the staircase Making of the signboard I have used a new process for the signboards of the Japan Post building. The case has been 3D-printed. The light comes from a new type of COB LED light strip. It is very narrow (2.7mm), can be cut every four LEDs, and the LED density is very high (480 LEDs per meter). It can be purchased from AliExpress here: www.aliexpress.com/item/1005003193200776.html Photos of the detailing process of the JPost building. The window blinds and shutters have been 3D-printed. The second floor of the JPost building is a kindergarten. The top floor windows are made of a sheet of clear/light blue acrylic. The window frames have been painted, then pasted on a sheet or mirror-like tape. Next up: the rooftop details. The electrical cabinets are from Matsuri Models (matsuriyamodel.booth.pm). On the layout, I use an LED control system described here: https://shin-yukari.weebly.com/led-controller.html. It is based on Adafruit 12-Channel 16-bit PWM LED Driver modules spread all over the layout. They allow a central computer (a Raspberry Pi in my case) to control the hundreds of LEDs fitting the various buildings. In addition, I needed a similar control box on my workbench. This is a description of the system I have designed. It uses the same Adafruit module and exposes the 12 LED outputs on terminal blocks with push-in connection, suitable for temporary connection (no soldering required, no screw). Here we see a building "under construction", with its wires attached to the control box. I have designed the PCB in Autodesk Fusion 360. The system is based on an ESP32 microcontroller connected to the Adafruit module and to the various connectors and terminal blocks. The ESP32 exposes a web page used to individually set the brightness of each LED.
The roof is fitted with accessories that have been 3D-printed. I built simple light boxes to simplify the lighting of the building. The front signboard backlight is made of a piece of polyester scored at precisely spaced intervals to spread the light evenly. After googling a bit, I learned that the intensity of the light in the backlight panel decreases exponentially. I then created a small python script that generates lines spaced exponentially, and used the resulting document to score the transparent polyester (or acrylic) sheet. The result is a uniform light distribution, even if there are only two LEDs at both ends of the signboard. Next to the school dance building is the Softbank building. It is based on the very popular Tomix 4051 Square building set (brown). https://www.tomytec.co.jp/tomix/products/n/4051.html Complete with 3D-printed figurines... ... and a nice wooden bench. The top floor is the music studio, with a nice glass roof. Each storey is lighted individually, using small light boxes.
The building next to the construction site will be a Dance School, inspired by the Tokyo Dance Haiyu & Butaigeijutsusenmon School building in Shibuya.
Part of the first photo-etching project, I built a tower crane, which will be the focus point of the new construction area. The tower crane is largely inspired by a real crane, the JCL008II. |
