Please note that the LPC series is available as OTP versions only. Your development phase alone might use more chips than the final project.
Not so, the LPC932 is out as the first ISP LPC

I built my own LPC programmer several years ago and since that it works fine.
Please doucument that, the fact that it has programmed some chips is absolutely no proof of anything

DO NOT claim that because something 'works' it is correct.
