Scrapeboard Builder's Manual
|
||||
============================
|
||||
|
||||
Scrapeboard is an alternative controller game that uses a skateboard deck and metal floor pads for input. The goal is to do combinations of moves in series as quickly as possible. This manual covers how to build a full Scrapeboard system. It includes how to install and test the software, how to build the electronics, and how to fabricate a controller using a skateboard deck, metal pads and plywood.

|
||||
|
||||
Scrapeboard is an alternative controller game that uses a skateboard deck and metal floor pads for input. In the game, the player is a lizard who is given a skatedeck by Tony Hawk and challenged to swords matches with a series of goons. The object of each match is to perform combinations of moves displayed on screen as quickly as possible.
|
||||
|
||||
The game is available to play at select game conventions and festivals, but it is also a D.I.Y. project that is not difficult to reproduce. This manual covers how to build a full Scrapeboard system. It includes how to install and test the software, how to build the electronics, and how to fabricate a controller using a skateboard deck, metal pads, and plywood.
|
||||
|
||||
Audience
|
||||
--------
|
||||
|
||||
It is intended for a general audience. No coding, electronics, or fabrication experience is required.
|
||||
It is intended for a general audience. There are steps that involve beginner level electronics and wood working. The instructions assume a bit of understanding about how to connect components when using the Arduino. There are steps that require the use of a drill.
|
||||
|
||||
Purpose
|
||||
-------
|
||||
|
||||
The builder's manual was created so more Scrapeboard systems can be built, whether by the core team or other members of the community. With their own Scrapeboard system, players can challenge themselves and their friends outside of events and host their own events. It is released with open licensing so that the finished system is free to be used in any context, including being modified or used commercially in an arcade or bar.

The builder's manual was created so players could build Scrapeboard on their own and challenge themselves and friends outside of events and host their own events. It is released with open licensing, so the finished system can be used for personal use, for example in a player's garage or basement, or commercial, like in an arcade or bar. It is also licensed to be modified, so the controller can be used for other games, including custom ones. With more Scrapeboard systems, whether built by the core team or other members of the community, access to Scrapeboard outside of occasional events can be made possible.

Introduction
|
||||
------------
|
||||
History
|
||||
-------
|
||||
|
||||
Scrapeboard started in 2017 as a side project of the exhibition STORE 2 at Babycastles, which Frank, Blake, and Clement, the creators of Scrapeboard, worked together on, along with curator Mushbuh and a team of volunteers. The team received a donation of a signed skatedeck from Tony Hawk to be added to the exhibition. After the exhibition, in preparation for MAGFest 2018, Frank and Blake decided, in the tradition of Babycastles, to turn the skatedeck into a game controller with the basic concept of making something similar to Dance Dance Revolution but using a skatedeck instead of the player's feet for input.

Scrapeboard started in 2017 as a side project of the STORE 2 exhibition at [Babycastles](https://babycastles.com), which Frank, Blake, and Clement, the creators of Scrapeboard, worked on, along with curator Mushbuh and a team of volunteers. The team received a donation of a signed skatedeck from Tony Hawk to be added to the exhibition. After the exhibition, in preparation for [MAGFest](https://super.magfest.org) 2018, Frank and Blake turned the skatedeck into a game controller with the idea of making something similar to Dance Dance Revolution, using a skatedeck instead of the player's feet for input.
|
||||
|
||||
The original prototype was created using the skatedeck, cardboard, aluminum foil, copper tape, and a Makey Makey. The skatedeck was turned into a conductive device by applying copper tape to the bottom of the deck and placing it on a platform made of cardboard and layered aluminum foil. In the center of the platform was a cross section of aluminum foil, separated from four other sections of aluminum foil outside the cross section. The four outside sections and cross section were connected to the Makey Makey with alligator clips. This served as a proof of concept for the game and even lasted through multiple events.

The skatedeck was turned into a conductive device by applying copper tape to the bottom of the deck and placing it on a platform made of cardboard and layered aluminum foil. In the center of the platform was a cross section of aluminum foil, separated by bare cardboard and painter's tape from four other sections of aluminum foil outside the cross section. The four outside sections and cross section were connected to the Makey Makey with alligator clips. This served as a proof of concept for the game and even was able to be used for a few events.
|
||||
|
||||
The next version of Scrapeboard used four aluminum street signs, a rug, an aluminum sheet, and an Arduino. Four rectangles were cut into the rug to frame the aluminum signs, which were taped to the bottom of the rug with carpet tape. The aluminum sheet was drilled into the bottom of the signed skatedeck. The Arduino circuit was designed using pull-up resistors and a program loop which turned each input low each loop so that it didn't require a ground connection anymore. This version was used for a few years for many events but required a lot of repair and maintenance before and after each event.

This version was used for many events but required a lot of repair and maintenance before and after each event.
|
||||
|
||||
A newer model was made in preparation for GDC 2022, using wood, aluminum street signs, steel anchor rings, and the same Arudino circuit. The aluminum street signs were drilled into four pieces of wood which were bracketed together on the underside. The steel anchor rings were fastened to the underside of the skatedeck using machine screws. By the end of 2022, this version had been refined to the point where it could last multiple events without needing repair, a significant milestone for the project because it opened up the possibility of the game being able to run without constant supervision.

|
||||
Although there are still improvements being worked on, the 2022 model is what this manual is based on and what the instructions will create if the optional sections are skipped. Since that model has proven to be relatively durable, we can recommend the steps to reproduce it as a simple method for Scrapeboard players to construct a system of their own. Further improvements are covered by optional steps and more will likely be added in the future.

The standard scrapeboard is a skatedeck with two round metal pads drilled into either end of the bottom. The pads are connected by a flat metal strip, creating a conductive contact across the length of the underside of the board. The recommended metal pads to use are actually anchor rings, ordinarily used to hook cargo to a tow cable. They are used because their unique disk shape and slightly raised edges allow for the best motion with the board. The board is subject to a lot of friction and pressure, so it's recommended to follow this manual unless intending to build a heavily modified version of the controller.
