Auxilliary LED controller demo video
« on: August 13, 2012, 03:55:00 pm »
I bought my LED lights from ADV Monster and am happy with them.  They looks like lights you could buy anywhere else and save $10-20, but the guy provides support and I don't begrudge him a couple $ since he provides support, unlike some faceless guy on Ebay in China.

That being said, he has an item he calls the ST Dimmer on his site.  It allows you to dim LEDs and add flashing sequences.  He is asking $30 for this controller.  It is a commodity item that can be purchased anywhere for $6.  THAT is too much of a markup, so I bought it elsewhere.

I purchased 2 of these dimmers and glad I did, because I burnt out the first one with faulty logic.  I created a grounding fault that melted it.  My logic flaw, nothing wrong with the controller.

The dimmer allows you to control dimming down from 100% down to 10% brightness on the LEDs and saves the last setting.

There are also a series of flashing sequences and the speed of each is individually set and controlled.  Pretty cool considering the brains of the devices are about the size of a dime.

Using a 5 pole relay, the LEDs are set to go full bright when using my high beam.

The one problem I can see is the buttons are very small.  The positive side of me killing the one dimmer is I opened it up to see how it works.  Pulling the buttons off, I see that I will be able to wire momentary switches of reasonable size to the chip.  The only thing left to do is to look for a good mounting location and come up with a design.  Right now, I am leaning towards putting the switches, and the brains into one box and mounting box on top of left fairing, near the lock pocket.  Not sure yet though.

So, without further ado, here is a video of the lights and controller in action.  Shot on a camera phone, so not great, but you will get the idea.

I like it - really visible!

So where is this "anywhere" that I can buy one for $6?  I'm planning to get some LED's here soon, and probably mount a set under the mirrors.

I just bought a couple more on Ebay.

I am putting together a demo on how to wire the whole thing together, including putting useable buttons in the circuit.  Of course I shorted out the test unit because "I am just gonna hook it up for a second"

Will put up pics and such in a bit.

In the meantime:
if not against the rules:

this is NOT me nor do I have any affiliation, just happens to be where I bought mine.

OK, so here we go.

The controller is cool.  It is not made for Bikes though, as the buttons are very small membrane type buttons.  The entire PC board, buttons and all is about 1.25" long and 3/8" wide and 1/8" thick.

I removed the white but, which is just heavy heat shrink.

The buttons came off with my thumbnail.  Just held in place with a little glue.

This revealed the area of the PC board I attached some momentary switches to to replace the membrane pads.

The second picture is the prototype stage.  Board is exposed and I soldered wires to each button area on PCB and then to momentary switches.

Third pic is the solder points on the PCB.  This was fun.  Glad I had a third hand and magnifying glass for this.  Those wires are tiny.

Fourth pic is heat shrink added.

I then hot glued the hell out of the solder points.  Figure this would give me some level of waterproofing and vibration damping.

Three holes drilled for the buttons.

One hole drilled for the leads.  The male leads go to the low beam circuit on my bike.  The female leads go out to the LEDs.  I have triple pig tails for each right now.  Each LED under my mirrors has a + and -, the two on the fork legs share a + and -, so that is why I have 3 leads of each type.

I also wired the relay, but forgot to pick up a diode.  SO can't put it in place and test just yet.  Will post pics and diagrams when successful.

The great news is I hooked this up and it all worked very well.  Using the large buttons gave me full functionality.  Up until I grounded out the + output.  Fried the board.  I have 3 more coming.  By the time I get those 3, I will have the diode in place and be able to test the whole system and ride with it to see how it functions in the real world.
