The principles here should guide the development of a Swadge’s hardware and firmware. Most of the principles here are guidelines, not hard requirements. When in doubt, talk out ideas in our Slack channel, #super-circuitboards.
General Design Principles
Swadges should not largely rely on at-event infrastructure and should be fully usable after Magfest.
This principle may be broken if the feature that requires infrastructure is really cool. Talk it out in the Slack channel first before requiring infrastructure.
At least one Swadge mode should have wireless connectivity features, like a PvP game
Wireless connectivity between Swadges may be less useful after Magfest.
If a Swadge is turned on and left idle, it should display cool flashing LEDS.
This idle mode should be as power-efficient as possible
Swadges should have at least one secret or easter egg
Swadge Mode Design Principles
Modes should try to fit the current theme of the event by:
Using themed sprites
Using a themed font
Using the theme’s colors
Modes should use as much available hardware as possible, including, but not limited to:
LED effects
Sound effects
Accelerometer input
Touchpad input
Modes should be polished, which means:
No bugs
Looks pretty
Has intuitive UI
Modes should be simple. Overly complex modes are hard to explain and understand, and users will engage with them less.
Guided tutorials are good. If there is one, force users to do it once. Tutorials should also be easily accessible to do again.
Learning through gameplay by gradually introducing mechanics is great. This is how Nintendo gamifies learning.
Modes should be designed with a playtime of 1-5 minutes per session.
Larger games should have a way to save progress at this interval.
Modes should save options between sessions.
Modes should have an incentive to play and should celebrate🎉 when progress is made. Incentives can be:
Unlockable assets (pictures, songs)
Unlockable gameplay (new characters, new levels)
A story that progresses
Getting a high score (this is kind of boring alone, make sure there’s flair🎊)
Hardware Design Principles
The Swadge shape must be designed to the fit the theme of the event
A distinctive theme-specific silhouette is preferable
The shape should consider ergonomics
The Swadge must be designed to be worn on a lanyard.
There must be two Swadge variants, one for pre-order and one for purchase at Magfest
The two Swadge variants should have a sufficiently distinct color scheme.
Think of the pre-order Swadge like a Shiny Pokemon
The Swadge should be physically durable. Use cases include:
Dangling on a lanyard when dancing at a concert
Being shoved in a tight bag during transit
If the Swadge uses new or delicate parts, destructively test them until we’re confident the failure rate is near zero.
The Swadge should only include hardware if it is used by modes.
For example, do not include an accelerometer if it is used by very few modes.
If applicable, have a way to calibrate analog inputs.
Battery life should last the duration of the event with standard use.
Physical user interface should be intuitive.
D-Pad input is common and well understood.
A dedicated mode select button is better than a button combo or menu option.
Buttons should have silkscreen labels.
The Swadge may have 3D printable accessories
If we sell accessories, they must be budgeted ahead of time and ordered at the same time as the Swadges themselves.
If being sold, print files for accessories should be made publicly available two weeks before Magfest.
If not being sold, print files can be made available as early as desired.
Manual Design Principles
The manual should fit on an 8.5x11” sheet of paper, double sided
The sheet of paper may be folded
A high-polish manual is hard to make and even harder to sell
