Daily Xpress' Parinyaporn Pajee recently profiled Prachya and his love for all kinds of gizmos, including the Mini Sounder (turns any hard surface into a speaker) and his Bluetooth mobile phone speaker, which is actually an old classic Bell-style handset. There's also the wireless Sony Location Free LCD TV, which works great on movie sets.

For the set [he] uses modified Sony Glastron TV glasses as a mobile monitor when he wants to look at the footage he’s just shot.
“My crew laughed at me at first but they soon realised that it was useful.”
Of course, he's also a proud user of the iPhone -- seems like every article I read about every celebrity in Thailand mentions the iPhone, and it's not even officially for sale in Thailand yet.
