This is GENIOUS! A very clever idea instead for legit macro pokemon. The only hack here is to the DS itself. Would love to get my hands the schematics for this!

In case you’re not up to speed with the world of Pokemon, nearly every species of this game’s titular creatures have a ‘shiny’ variety – a differently colored sprite for each pokemon. As far as gameplay goes, they’re exactly the same as their non-shiny brethren, but the shiny varieties are so impossibly rare not many players have seen them. [dekuNukem] over on Youtube has come up with a great way to find these shiny Pokemon automatically with the Hackaday reader’s favorite tools – an Arduino and a few parts from Sparkfun.
The build hinges on the fact that all shiny pokemon have a short animation whenever the player encounters them in the wild. This setup uses a fishing rod, so an Arduino Micro first presses the Y button to cast the rod, while the ‘duinos ADC listens to the audio signal until a bite is indicated.
