Story

Abraham bought this model kit in Japan 2 years ago in ドン・キホーテ thrift shop. It's been stored ever since but during Sep 7 and 8 a modelling contest was held in GDL,. This is the first model I try to assemble I think I spent over 20 hours, it is not so hard but I am just not skilled cutting, aligning, painting and gluing.

The kit is a Billy doll house kit you can also acquire it on amazon US it will ship to Mexico too or can get it on ebay.

Ramen Kit

The instructions are on Japanese but they have good visual aids and kit comes with everything you need: wood pieces, plastic, carton, tint, glue, etc, etc.

1 / 2

I was stuck figuring out how to do the bench because none of the listed pieces matched the illustration, thank you google translate! I had to use chopsticks, we order a lot of sushi so we had plenty of them.

Fortunately Abraham has amazing tools (he is INDEED a hobbyist) so cutting wood pieces with this weird cutter made my life easier.

Stain stain stain

Bought fairy lights on a local store and made the wire shorter so I could fit behind the ramen banner. I thought of adding some sound effects so I used circuit playground express.

And the lights!

Testing lights with 3V coin battery

I also had some cute fabric I bought in Japan and used for the placemats instead of the little pieces of paper.

Blue placemats

The kit has cute items like the ramen bowls and spoons ^^ the chopsticks are left overs of other pieces of wood used to make the windows. Notice at this point all the stains in the banner, nabe and menu I wanted to give it an old-fashioned ramen shop look with grease hehe.

1 / 2 • Placement n_n

Back to CPX I used the following tutorials to play wav files and use touch pins.

This is the audio tests:

いらっしゃいませー！(Irasshaimase!) Is a greeting used at almost every retail establishment in Japan.

Playing wav files on CPX

I used a piece of stripboard to place a transistor and control the banner lights with CPX, I wanted to have an independent circuit for the lamp, so I just connected to a different pin in CPX and added a 220 Ohm resistor. A rechargeable battery and the TP4056 charging module.

Testing lights with CPX

Not the greatest assembly, but also used screws and bolts to attach the CPX.

Circuit on bottom

Added a piece of fabric to cover the capacitive touch (screws).
