Modest Improvement to a Harbor Freight Led Flashlight
Intro: Modest Improvement to a Harbor Freight Led Flashlight
I picked up a sweet little 9 led light from HF for $5 and it was kinda flaky, shake it and the light went out, so I'd thought I'd post my improvement.
STEP 1: What's the Problem
The positive connection is a spring loaded pin pushing against a blob of solder. High resistance and just poor contact.
STEP 2: I Had Thought to Just Use a Mini Connector
But had none on hand. So I grabbed a 4-40 nut and tinned it up.
STEP 3: Disassemble the Flashlight.
Unscrewing the ring with the hex opening let's you remove the led module. Now just solder the hex nut to the central solder pad.
STEP 4: Okay
The nut makes a tight socket for the pin on the battery compartment, it also compresses the pin farther, so now no matter how hard I shake or drop it the light doesn't flake out anymore.

Not sure if you get notified of this but see above to get the LED bd off when the front won't unscrew.

No respective but why not just get a Cree or PX module and through it in there? I use HB for Free Shears and tape Measures. The torches would be just for housings. Just saying.
