1. Scores should not go negative
|
||||
2. Konami Code position doesn't reset on non-sequence button
|

5. Make setup mode less confusing
|
||||
6. Allow jam clock adjustments in setup
|
||||
7. Unified build with multiple firmware targets
|
||||
8. Debounce buttons
|
||||
9. Pull-up NES data to prevent going apeshit when you unplug the controller

LED Roller Derby Scoreboard
|
||||
===========================
|
||||
|
||||
A do-it-yourself LED Roller Derby scoreboard.
|
||||
It's visible in full sunlight,
|
||||
doesn't use a computer at all,
|
||||
and can be easily operated by an 8-year-old.
|
||||
|
||||
If you're looking for a software scoreboard (using a projector)
|
||||
this [list of free derby scoreboard software](http://woozle.org/scoreboard/others.html) will help.
|
||||
|
||||
This scoreboard is operated with a Nintendo controller,
|
||||
and runs on an XBox 360 power supply.
|
||||
The rest of the parts need to be ordered from various sources online.
|
||||
The total should come out to around $200,
|
||||
with plenty of options for upgrades.
|
||||
|
||||
It will take about 6 weeks of work,
|
||||
and requires basic electronics understanding and
|
||||
elementary soldering skills.
|
||||
I provide updated firmware,
|
||||
so unless you feel like modifying the MIT-licensed source code,
|
||||
you don't need to do any programming.
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
Resources
|
||||
---------
|
||||
|
||||
* [Discussion Group](https://groups.google.com/forum/#!forum/scoreboard-builders) for help from others who've built or are building one.
|
||||
* [Google Drive Folder](https://drive.google.com/folderview?id=0BzovkpI6mzWQNFc4eGN0aGoyTGM&usp=sharing) with
|
||||

About Me
|

|

|
||||
I'm Neale Pickett,
|
||||
also known as "Q" in the Derby world.
|
||||
Feel free to [email me](mailto:neale@woozle.org),
|
||||
but the group would be more appropriate for email relating to this scoreboard.
|
||||
|
||||
I've done a lot of [other derby stuff](/derby/)
|
||||
that you may be interested in.
