Hi all. Would appreciate review & suggestions. Bill Marsden recommended I start a new thread. So this is really a spin-off of this thread: http://forum.allaboutcircuits.com/showthread.php?t=18613
Attachment 1 is a re-draw of Ron H's & Bill's design in the aforementioned thread, since I want to use it on my motorcycle. I've substituted the parts I have on hand, changed the supply to 12V, & included the LED string connection terminals (closest match I could find in Eagle). Please see attachment 1.
Only thing not shown is a miniature H
O proof switch (appropriately rated) mounted in the cockpit. I use a fused, ignition activated, busbar to run all my farkles, so the power will come off that to the switch to the board.
Bill did ask about the voltage range/fluctuations. I've measured the volts between 11V to 13.8V, but I have seen it go below 11V (at idle w/ several accessories on, primarily High Power Aux Driving Lamps, ECM & heaters, which I've learned to power down at such times) & up to 14.1V (at start-up with power hungry accessories off). But typically it's between 12.1V & 13.5V at cruise & idle.
Background: I use a lot of LEDs on my bike(s). While not the greatest, I like the T1 3/4 (5mm) Superbrights. The typical Vf is 2.1V, but sometimes it is higher when I use blue, UV (yes, UV, but that's another story ), etc.. Naturally, the number of LEDs in a string are adjusted appropriately. I have yet to run any of the LEDs at their max amps, 18mA is nominal. A good example is the license frame. These are typically at 5mA in the run mode, & boost to 18mA when the brake is activated. I use 3000mcd Reds in this application & they are attention getters. I have a major supplier near where I live & the price is right. I typically make my own housings/mounts. Sgt Wookie (especially) & many others on this forum, have assisted me in the past with the two methods shown in attachments 2 & 3, & they work very well (but they have drawbacks which have been discussed in other posts).
Attch 2 is used to activate combination running/brake LEDs mentioned above. Usually these are on the license plate frame & bags/trunk. Attch 3 is for constant running lights. Sometimes I also use Atch 3 following relays to twinkle running-lights with my turn-signals.
Anyway, if a look-see can be had for my re-draw of the design, I'd appreciate it. Thanks for your invaluable assistance & time.
OT: I did learn how to print-screen into MS Paint. Now if I could just learn how to insert it into the darn text.
