MR16 LED controller

[RJ]

This Project is for a 16 channel controller designed with the sole purpose of dimming the MR16 spot lights. It is being optimized for the current MR16 leds that Wirekat sells which have 32 leds on them.

It is really a finished design with afew beta  boards being ordered this weekend. It uses mosfets to provide current enough to handle 12 MR16 as a target per channel and it has 16 channels.

This provides control for either 4 Red/Green/Blue light cannons with up to 36 MR16 each. Or 3 Red/Green/Blue/White Cannons with 48 MR16 each.

The Parts cost will be in the $20 - $25 range and it is a small pcb of just 4" x 3.5"

It is powered by a seperate computer type 12 volt power supply with enough current to handle the lights attached. Each Mr16 is about  .17 amp to drive.

All connections to the board are made by 1/4 spade connectors.

This works on the Lynx drive circuit and the Firmware is special firmware for MR16 that I created for the lynx to dim them.

Looks great.

I have something that may be of interest to some who build these and that is a small PCB that has the motherboard style molex connectors and switch wiring so you can just plug in an ATX Power Supply, it has normal screw connections out.
It is a home etch board that i'm happy to post the pdf file if anyone wants to make one.

I made it for my own use but could be useful for anyone wanting to use computer PSU's.

the attached image is the first build - i have made a couple of small changes but it is essentially the same
The board measures 3"x2" - a 20pin or 24 pin atx socket can be installed along with the 4 pin aux socket

This is really cool!!  Thanks RJ.

If you want any beta testers on this project, I have my hand raised. 

I have 40 of the MR16s from Wirekats most recent group buy that I can play with.  I'd be happy to help out.

I have 235 MR16s that I need a controller for.

My had is up for a beta tester as well.

Thanks

Looks great Phil!

Got the case in for the MR16 / LED controller today. Heres a pic of what the case looks like with a print of the pcb in it.

Nice find RJ. Looks like it'll fit well!

RJ,

I'd love to be able to beta test the new controller.  I'd really like to find something to replace the D-Light Boards I'm currently using.

Any chance you could release the project as a board only?  I was looking at the PCB and I already have the components in house.

Nice ATX adaptor Phil

Not sure yet how it will be done.

Well,... I'd be willing to Beta test and be his new best friend.  So there ...You are not allowed to view links. Register or Login

I have finished the MR16 Controller Design and will now order a few PCB's if the pcb's come out well there will be a coop for them.

Here is a video of the test on it.

RJ,

Once again you've outdone yourself. I don't think I have to tell you "I can't wait!"

Well done.

Curious RJ,

I went back and looked carefully but did'nt hear you mention, in your testing did you use an AC or DC 12 volt supply for the MR16s? I remember that these could be run with either per Kevin (Wirekat) I really liked the results and would just like to know which provided the great results.

Thanks

Leon
