How to - Hack the Net and have it Tweet?

The most interesting thing with The Internet of Things is not when we connect "smart" stuff but fully basic and dead technologies.

This post will roughly describe on how to hack a Floorball goal. One of our first post on this blog - years ago was on the similar subject - self indicating nets that through a basic bell would have a basic audible ring to it when the net started to move = someone scored. We still think this is a splendid idea as playing Floorball with small nets and maybe with kids...

Here a basic and fairly low-tech net - Image via the IFF's flicker stream
Here is the recipe for the big league as we need something better:
1 Standard net
6 Light detectors (see image below)
1 Small solid state memory
1 Little card and some software to run as a controller and a small power supply (battery)
1 regular smartphone

This is how you can do this - we hope ;-D
First take the 6 light detectors you have

Maybe you have six i phones laying around and can take the cameras out?
Mount two on each side - inside of the posts of the net facing each other. Mount two on the top facing down.

Then you must connect it all together and have a way to run your software and the streaming images so maybe a raspberry pi board module for $30 bucks would do the trick?

OK ok we know you also probably must consult with a nerdy tech uncle on how to do this.
But if you have software that is optimized to see the ball and knows when the ball of the very specific color (no, you do not calibrate the cameras with a white balance -but with a ball color balance). Then the software must also know when a ball of this color passes the very specific goal line (if not the light color changes). And as long as the cameras are fast enough and can work together..and then have the goal line calibrated too.

Well a connected smart phone should easily be able to automatically tweet to the internet - not just only that there was a score recorded - but maybe also what the score is if both goals are connected - and include live footage from goal line cameras...too? Wow that nerdy uncle has a few things to fix...

Cost? Not too bloody. Time? Well ask the uncle again...

So who works with Floorball goals developments?
A kickstarter anyone?

And if this will not work you tell us why - OK!

OH, one more thing. In the Ice Hockey world we recently saw goal posts, designed like organ pipes or something - so when the puck sailed into em' - it chimes galore. Why? To make practice more fun we think... So there you go - 2 net hacks in one post at Floorballcentral. ;-D

Research suggest that eye-injuries are more common in Floorball as compared to Tennis, but less common as compared to Squash (similar to Racquetball).
To minimize this risk of injury Floorballcentral recommend: Use certified protective eye-wear (mandated in many European areas for the youth). Do not lay down on the court. Follow the rules strict on stick height.

Also if you get addicted to this sport - do not blame us!
