When [Anton] picked up an old translucent purple Game Boy Color, he noticed a nearly complete lack of sound coming from the speaker. This simply would not do, so [Anton]replaced the speaker and soldered in a 2 Watt amp (http://blog.avrnoob.com/2012/10/game-boy-color-loud-sound-mod.html), making his Game Boy very loud indeed.
After cracking open his Game Boy, [Anton] noticed the speaker was rusted. He replaced it by soldering in a speaker from a Motorola cell phone, fixing the most immediate problem. After plugging in a few batteries, he still noticed a nearly complete lack of sound.
Turning to his electronics junk drawer, [Anton] pulled out a TI TPA2000D1 Class D amplifier (http://www.ti.com/product/tpa2000d1). This tiny amplifier is able to provide 2 Watts to a speaker and is very power efficient given it’s Class D pedigree.
After making a PCB and wiring up his amp to the Game Boy’s circuit board, [Anton] spent a little time tracking down the source of some high-frequency hissing. As it turns out, the power regulators and converters on a 15-year old Game Boy aren’t of the highest quality, but after adding a few capacitors [Anton] got everything under control.
Now [Anton]‘s Game Boy has very loud, crystal-clear sound. Considering the lengths chiptune artists take modifying old ‘brick’ style game boys for use with Little Sound DJ (http://littlesounddj.com/lsd/) or nanoloop (http://www.nanoloop.com/), [Anton]‘s build could become a worthwhile modification for musicians looking for a little more oomph to their performance.
