Hardware 3ds c stick mod

[Sonyeoneon]

Some idea about how this can be possible? In the description he says that use a costume circuit board to use it as a circle pad pro without the infrared module, so, someone know or have an idea about how it works?

Probably removed ir receiver and ir blaster (in cicrcle pad pro) and instead soldered it together

So theoretically if i were to solder the ir sensor and the ir blasters together from a 2ds and a circle pad pro, I could recreate this? or am i missing something
