There are plenty of UHD monitors around. I've got a £600 32" IPS (BENQ BL3201PT) which I can't praise enough. It is a fantastic display. There are many more at 28" with prices £250 upwards.

I used to have a dual monitor setup but there is no way I'm going back to that now. It is that much better.

Ha, ha. I think you missed the bit where I said I paid £550 for the system (new).

The focal length is approx 60mm. I see the advantage in increasing this but due to the bed depth, my options are limited. Something to look at anyway.

My air pressure is 0.02MP (3 psi) and does a good job of keeping smoke away from the lens but probably not a lot else. Increasing the airflow is an option but I think the air exit nozzle needs improving as well.

I have air assist cutting which is why it can get through 6mm acrylic though I don't think it is very well designed. The kerf is wider at the top than the bottom and is noticeable on 3mm which implies the set up is poor. I suspect a poor beam shape but haven't confirmed it. Any suggestions on what to check are very welcome.

I have a £550 Ebay 50W laser which can cut 6mm acrylic well (though with bevelled edges currently - I'm hoping to be able to do something about this though with some better set up). I've done 6mm ply but it all came out rather burnt. Again, I'm hoping to do better once I find the ideal settings. Overall I've been impressed with what it can do for the price.

Submission + - SpaceX Landing - Picture and Video from Barge

Maddog Batty writes: Last months Falcon 9 1st stage barge landing attempt was unfortunately a failure but it was very close. An official photo taken from the barge has now been released showing the rocket just before landing. There is also an unofficial video from the barge, which shows just how close they got. In particular, the "hover slam" method of landing where the rocket engine produces thrust to weight ratio significantly above 1 to rapidly reduce velocity just before landing seems to work well. This method compared to a gentle landing uses less fuel but the throttle up needs to be performed at exactly the right point so as to bring the velocity down to zero as it hits the deck.

Why would anyone get a projector when 60"+ TVs are much cheaper than good projector + nice screen + extra bulbs?

Because we don't want a 60" screen in the living room where as we do have the ability to hide a projector screen in the ceiling. Currently we don't have a TV at all and want to keep it that way.

Go and ask any timber merchant for a bit of 2 by 4 and they will know what you are talking about but then ask them for what the actual size is. They will give you two answers, one for sawn timber and one for plained timber. The answers they give will be in millimetres and neither will be anything close to 50.8mm x 101.6mm. The length will also be given in metres.

Comment In other news: Are 4K displays worth getting yet? (Score 1) 204

I was thinking about getting a Asus PB287Q 28" 4K 60Hz as it has good reviews but was unsure as to whether I can stick with icons and stuff being small. I love the idea of the additional pixels as I always seem to not have enough but I here some programs aren't a good match as they don't scale well.

Anybody use a 4K display for programming / development work? Good or bad idea?

Submission + - SpaceX Landing Video Making Progress

Maddog Batty writes: The fine people at the Nasa Space Flight Forum are making good progress on restoring the corrupted landing video reported earlier. It worth looking at the original video to see how bad it was and then at the latest restored video. It is now possible to see the legs being deployed, the sea coming closer and a big flame ball as the rocket plume hits the water. An impressive improvement so far and it is still being actively worked on so further refinements are likely.

The trouble with money is it costs too much!
