Will - Yes, post more pics.

I just sent you a PM. Kirk

A few more photos:

That new glass looks pretty invisible, doesn't?

If you change the angle just right, you can see that all those 4 heads had the UCL glass in them

With help from some aluminum parts from Mirage_Man and some time in my lathe, I am working on a new variation of the heatsink for these 4 custom lights. Once I get the drivers from George, I will be able to do the final fitting:

Hang in there guys - these lights are coming together just fine

Another update!

George just finished the first batch of drivers and I was able to get enough from George for this build. Once I get them (probably no later than next week) I will be able to complete each light, one at a time. I will post here again as they get ready

Thanks much for your patience

Will

Drivers did not arrive today, but I was able to work on one of the custom bodies today. You can see additional details/photos here.

Great work Will! I like the looks of the FM 1C. I may do that to mine too.

Thanks dude

The drivers have arrived :naughty: :naughty: :naughty:

OK folks, lights are starting to come together now that I have the drivers!!!

I finished fitting all 4 reflectors to their new heads:

Today I started the fitting of the HS and the plastic washer that prevents the head from crushing the LED:

Will - Great pics. Kirk

OK, more pictures from today!

Today I worked in turning the switches from ON-OFF to momentary on, which is what is needed for the drivers from George which need a momentary switch to go to ground to be activated.

In the photos below you can see that the botton contact on the switch is now negative (ground in our system) so when the button is pressed, it provides a ground to activate the switch. The switch input to the converter will now come from the old positive contact at the top of the switch. There are probably other ways to do this, but this is the one I picked

Routing for the wires:

Eliminating the ON-OFF, by going from this:

to this:

Epoxying the new positive contact - note that solder blob is higher in the middle, so even flat top cells will work properly here - no magnets needed!:

I got two switches done today:

Almost there - thanks again for your patience guys

OK guys, I think that this is "the" weekend to finish the lights

I have a few minor steps before soldering the drivers, dry-testing all connections, secure the drivers, and do final assembly

The only light that will take longer to finish is the 2xC since this uses the bFlex (round nFlex) and it will take some additional fitting due to the board being bigger than the MaxiFlex. But no worries, we are almost there folks !!!

Will - thanks for the update. Keep those pics coming! Kirk

Come to papa you little X bin

Great progress today. More pictures :naughty:

Starting to wire drivers:

Calculated power to see if I needed additional heatsinking on the MaxFlex. Although my design goal has been for 1.0Amps, these drivers can deliver up to 1.4Amps, so it looks like I will be making these 1xC McG45's a little bit more robust just in case you crazy owners decide to want "more"

So I found out how to get a metal "spring" with thermal AA on both sides to attach to the thermal pad George provided on the MaxFlex:

Before I glued the converter to the HS, I tested it, of course!. As expected, the light came up at its default value of 350mA, which at its lowest level draws 50mA from a 4V supply:

Then glue the converter:

and then glue the HS to the switch:

ta-daaa:

and a quick test using an actual 18650 cell, on its actual host (this LED was for the finned FM 1xC body):

same photo with overhead light off to appretiate the LED being ON:

Then I did the other two 1xC HS/Driver combinations (leaving the 2xC for last due to being quite different):

And that is all for today. More photos tomorrow
