They were pulled somewhere between 4 and 5 minutes I suspect closer to 4 - within 4:05-4:15, the first hint of smoke made me act.
I definitely have to do something to the popper to slow it down as its far too efficient at getting heat into the roasting chamber.
If you look above you can see some of the earlier roasts were quite light. They seem to go from that to what you see in the Mysore in a 20-40 second window.
I stuck the tin on mainly to reduce loss through high bouncing, was previously losing 10-30 beans, now lost between 2 and 5 beans to bouncing and maybe 5 more in hurried pouring and vigourous sift cooling.
I have uploaded the video of my roast #2 http://www.youtube.com/watch?v=IxXKWT0qD3c its a four minute video - any comments feel free. Many mistakes Im sure for myself and others to learn from.
Forgive the cinematography I was roasting coffee and somewhat preoccupied. ;D

Does this all sound a bit quick?
Yes.

Any tips on stretching these times out or slowing if down a little?
There are plenty of threads with tips; do a search.
However, personally I prefer to avoid trying to modify anything electrical and recommend introducing more cool air and allowing more trapped hot air out.

Great video - has a Blair Witch Project feel to it!
You pulled the roast mid first crack. Try waiting untill it falls silent again, then wait anything up to 30 seconds before stopping it I recon. Should be just before second crack then.
You may like to try a really dark roast for experimentation just to see what happens when you go into second crack. It would taste rubbish and pull it when it starts to smoke like hell (thats all the oils burning off), but it is a great way of learning the different stages of roasting. Try not to burn your house down...
I often wait for the very first bean to go into second crack which has a very distinctive sound, then halt it - got to be quick with the popper though!
Those later roasts follow the above nicely - have you had more goes since?
I have done a few roasts post the youtube one. One that started to smoke just as I pulled it, tasted too much like Vittoria for my liking so I wont go there again, was post 1st crack, but did not make cracks again.
Currently waiting for some
a) time
b) cool weather
c) no rain
d) less roasted beans to use - got 500gm roasted to use up
before roasting some more for ourselves. I have made some minor mods to the popper and am tempted to repurpose an old cpu fan and some flexible tubing to introduce cool air into the roasting chamber to push out the times further. Have managed to get at least an extra 60-90 seconds depending on ambient temp.
I just got to get it right so I dont make oily beans (which I assume is a bad thing) more playing about to do. Currently hanging out for the next greenbay and will grab a stack more of whats available today and whatever is available then
