    Program to model heat flow

    I use Lisa. Not what I would call "user friendly" but if you have a decent grasp of heat transfer it does a good job of FEA and the price is right. http://lisafea.com/

    Quick led polarity question (SST-90)

    With some drivers the LED positive and negative are NOT the same as power positive and negitive. If you connect the heat pipe to one of the power pads then you have to realize it is now part of the circuit and may have to be isolated from anything that is grounded.

    Try alloy 145 and you will never cuss copper again.

    Need help designing custom copper MCPCB for an XML

    For those of you that aren't afraid of "heavy lifting" there is a finite element analysis program with a thermal modeling component at a price that is way below the "pro" programs. It is from Canada and called LISA. It is NOT user friendly but great for the price. ($50 CDN) Just don't come to...

    New LED website from Newark

    Thanks for the links PW. Digi-Key also published a good design guide for LED's. These are a "must read" for anyone that builds a high powered LED light.

    Soldering SST90 to Copper Disk with Indium

    As those who have worked with the SST/R90's know getting 20+ watts out of a contact area of ~46 mm^2 is a challenge. The Luminus Devices star and other metal circuit board designs are a good answer if you can incorporate the form factor. For my helmet light design I decided to use a copper...

    Good aluminum for flashlights and/or parts?

    Yes Fred, I suppose I could call it artistic and double my price. :whistle: Have any of you used 6020 alloy. It has much better specs than 6061, is rated higher for machinability and anodizes great; just hard to find. McMaster has it for 3 arms, 2 legs and all your kids. I emailed Alcoa and...

    Good aluminum for flashlights and/or parts?

    Speedy Metals 7075 S*** for aluminum streaks horribly when anodized due to poorly homogenized alloying. The crap comes from Russia. It took me four weeks to pry the country of origin out of Speedy Metals. See for yourself: :thumbsdow

    Optical comparator light modification

    I think your heading in the right direction. A SST90 would give you a nice flat field source. You had trouble with posting links because you need a minimum number of posts. This discourages spam. I would be willing to help you with this but would prefer to do so via email. I will PM you...

    Optical comparator light modification

    I think a Luminus Devices SST/R 50 or 90 would work better in you application as the SSC P7 is composed of 4 separate dies and there is a gap between them. This would mean you would need a diffuser to eliminate the dead cross created by the 4 die gap and diffusers are very inefficient, like 10%...
