There were lots of hands in the kitchen, and Mike's was one of them.Someone else designed the physical mounting, someone else designed the overall size and layout pattern, etc. Someone else actually CAME UP with the project in the first place.Mike's part was large, but Mike was not the only player, here.If Mike is anything like me, kudos are not his motivation, anyway.

content: I'd rather get paid than credited. Mike looks to be a sub-contractor here, enlisted to bring someone's vision to life. He's not really the star of the show. They didn't credit the guys that hung the panels either.(Edit: It also looks like the video is a portfolio piece for the design team. Mike probably has his own marketing material, which is going to be focused more heavily on his work than the designer's.)Anyway, he got his credit on the site. Anyone who cares knows where to look. And those whoreallycare get the cool reverse-engineering videos too, which would bore the hipster fans somewhere between "Hi" and "today we'll be reverse engineering an iPod Nano LCD screen".

I've looked and looked, and I'll be damned if I can find any of those ipod screens he said were dirt cheap. He must buy in real quantity through a supplier that doesn't advertise or list their parts on the web anywhere. or maybe I just forgot how to use Google ... definitely a possibility.

I snagged that sucker and it works perfectly, but only goes to 3000fps. It must not be the same model... Anyway, if I hadn't viewed your video previously I would have skipped right over it.thank you.edit: oh yeah i should learn how to process and output video on an FPGA before I order. *cancels order of 1000 displays*

Sad in a way but whoever it was did a good job and I am pleased with them.Engineering (in general) is a particularly unusual profession, rarely remembered. Even so, it touches everyone daily and is amazing to see what is and has been built over the years.

I find these kinds of projects super super interesting, and have a curiosity question about the process: Do you end up needing to do any kind of testing/compliance certification? I'm thinking things like FCC, UL, etc. I've done some reading, and there seems to be a lot of conflicting information out there.

content: I found another use for a smartphone display today. Looked at this a few times from afar, but today looked up close. They used a high resolution colour TFT smartphone display for a lift indicator. You cannot see any jaggies, so it really is overkill using a high resolution display when a much simpler unit would have done the job. Kone lift in the hospital,I am spending way too much time in there unfortunately recently.

content: I was asking Mike, but I'm kind of curious how the sellers are able to supply these quantities. I was under the impression they were perhaps from factory rejects or damaged iPods, but these seem like new items, so perhaps direct from the manufacturer.Interesting aside: the Nest thermostat has a custom LCD - it's circular... Oddly, only the pixel array is, the actual display glass is square.http://d3nevzfk7ii3be.cloudfront.net/igi/xMQM5UAtkAbVdFZL.hugehttp://d3nevzfk7ii3be.cloudfront.net/igi/oYnUQSyTWUSvrFXW.hugeI don't know why they went to expense of doing that.

Cab drops us off at 69th & York, my dad and I walk around the campus for at least 2 solid blocks, still not seeing it. So I open up the Vimeo video to try to make sense of my surroundings.. Then....
