Re: Low buck projects- Let's see 'em!

I bought this LED flashlight at the dollar store for $3.00



Here is the circuit board inside:


I cut it into two sets of 9 and a set of 6:



It took 5 minutes to modify the circuit to optimize it for 12 V:



Test it out. Perfect:



The original fixture is forty years old, and the guts were all corroded. The reason for the project. I glued the circuit board into the old fixture with some silicone:



Beauty. Excuse the rain:



It draws 45 mA. The original 6W bulb draws 500 mA. It's now brighter, although the LEDs are somewhat uni directional. The original lens diffuses the light enough that it is easily seen from any forward angle. I did both sides. I might use the 6 LED section for the stern light.

Re: Low buck projects- Let's see 'em!

Did you put the resistor and jumper in there? What value resistor did you use?

Re: Low buck projects- Let's see 'em!

Yes. I used 68 ohms. I also had to file away the traces on the circuit board in 4 places. This value resistor was calculated based on the voltage drop of the LED's and the current of the LED's. I would be happy to explain how that value is calculated if there is interest.

5 years ago, for $35 you could chose one of the above items for that price.

Anyone know of small stand alone LCD screens that could combine with one of these puppies (without the need for a computer) for an engine room camera?

If an engine room camera and remote monitor is what you want, I would think one of the "backup cameras" you can find on line for much less than $100 would do the trick. It is all 12 VDC with no need for any converters.

Check this one out:
Amazon.com: 7 inch TFT LCD Digital Car Rear View Monitor with Waterproof Car Rear View Camera combo: Automotive Amazon.com: 7 inch TFT LCD Digital Car Rear View Monitor with Waterproof Car Rear View Camera combo: Automotive



The trick would be finding one with a weather resistant monitor. All of them have weather resistant cameras but the monitor is intended to be mounted inside the car/truck.

After School was launched yesterday. Slip 6-51 buddy. Pretty lonely on the dock so far.

Re: Low buck projects- Let's see 'em!

Dock bumpers... Cost $27 total for 3.

90 degree brackets... 2x4, noodle float (replaceable) and outdoor carpet...



Ok, there are no cleats on TOP of our docks, only rings on the vertical of the fingers. My boat fits tightly in the slip (there is 9 feet between fingers boat is 9'2" wide at the deck). With large fenders, they rubbed harshly against the dock, I needed something wider, and thinner that was removable. My wife came up with this idea, and I think it was pretty genius.

$24 for a 5'x26" piece of outdoor carpet backed with rubber.
$2 for 2 noodles.
I had the 2x4s.

There are (2) 5' ones for port/starboard, and I created one that is 4' wide for the bow.
Bene505 and katsailor like this.

Re: Low buck projects- Let's see 'em!

It is generally not advisable to put white LEDs into nav light fixtures that were designed for incandescent lights. LEDs emit light over a very narrow range of wavelengths, and when put through traditional incandescent color filters the color fails to meet USCG requirements because. For instance, the green nav light on the starboard side of your boat tends to be blue colored.

I'd suggest checking this out carefully before you all get too excited about this mod.
