He probably used a capture card because that's probably what he had laying around. I've been sensing an increasing case of raw panic in the shenanigans since the first "prototype" video. Everything makes sense once you imagine a solo non-tech savvy guy putting together whatever he can hours before his homework is due.
On the bright side, while he pissed off a lot of people by lying to them and wasting their time he hasn't actually swindled anyone. If he ends the charade now and doesn't move forward with the Kickstarter at the very least he can bow out without ever having taken a dime.
I'll give the first Indiegogo the benefit of the doubt as a big dream gone sour without any ill intent, meaning he can at least maintain the dignity that would come from cancelling his new Kickstarter plans and not try to take money from people while now knowing for sure that he can't deliver. At this point a Kickstarter would certainly fail but given the recent events it would be a failed swindle. I hope he has the integrity to at least stop at the point of engaging in a bald-faced scam.
