MR16 Parts Coop...is there an interest?

[ponddude]

I had contacted RJ  few weeks back about doing a COOP for the parts on the new MR16 boards.  Than I went on vacation and it kind of got pushed to the side.  With the boards probably arriving pretty soon I was just looking to see if there was enough interest in people getting the parts still.  If so I would gladly do it.

I don't need to know how many kits you want (yet) but rather just want to check to see if there is an interest.

Let me know.

Greg,

Put me on the "interested" list.

I am interested also

[trekster]

Greg, are you going to do the COOP?  You can count me in.  I have pcb's.  A parts only kit would be great.

You can add me in on that one. 

[Ron]

I'd be interested.  Any thoughts on having two options, one for the high current build and one for low constant current?

Ron

[lortiz]

I'm interested as well...

I would go for some too.

John

Interested.

Wish  this opportunity and the dongle enclosure coop materialized earlier. I bought MR16 parts and dongle enclosures while waiting for my LE Express & MR16 kits to arrive. Live and learn....

Yes, that was the plan.

Now in order to make this work from the quotes I got back from Mouser, we are going to need at least 50 kits.  The constant current option is fairly cheap simply because the MOSFETs are the most expensive part of the unit.

I will get all the info together and post a coop some time tomorrow.  However, unless it is very cost effective we may end up not going through with it.  We shall see.....

The Mosfets are the problem, I looked all over the place, and can't find anyone that has them, unless someone has a stash......

[occhristmas]

I would be in for 4 kits - however I was not able to find the mosfets anywhere either!

[Rainlover]

I am confused by the term "Constant current". Does that mean it is constantly on?
Sorry to be so dense.

Constant current is a term you will hear when people are talking about lighting LEDs.  LEDs do not like fluctuations in current and will work much better and longer if they receive a constant value of current.  You'll also get consistent brightness.   Basically constant current smooths out the fluctuations on the input voltage and provides constant current out.

In this case you can build the Lynx DC board without the mosfets and use each channel as a constant current device delivering 100mA.  Then you can build your LED circuits with the 100mA value in mind.

Hope that helps.
