DIY ALS Mini Flashlight Mods

Recently popular ALS mini flashlight, the thing is pretty good, but there's always a hiccup when using it. Almost every time I use it, it's out of battery. However, it scores full marks for portability, and it's still pretty good to keep in the bag.

The problem lies with the switch being prone to accidental touches. How should this problem be solved? Maybe a double switch could solve this problem. So let's take a look at the modification below.

Cut the red wire there, fly the wire to the tail and connect another small switch in series.

The small switch on the tail is taken from a CD drive, the type that automatically springs back. As long as it's the right size, it can fit in. One end of the cut wire connects to ground, which must be nearby, conveniently connected to this through-hole; the other end connects to the switch, which requires a flying wire.

The original use of the black soft wire always caused problems when installed. Perhaps the wire insulation was pressed by the battery, punctured by the right angle of the circuit's drilling, causing a short circuit, hence the subsequent switch malfunctioned. Enlarge the edge of the hole a bit more, make it not a right angle, and replace the wire with thinner enamel-coated wire to solve the problem.

After enlarging the hole on the back, apply some tape for simple insulation

If brightness isn't a major concern, these two resistors can be connected in series, extending battery life to about 3 hours.

Here also requires a corresponding modification, depending on the specific shape of the switch.

And finally, the finished product picture.

Of course, one of the screws definitely can't be reused.

When using it, press the original button with your thumb and touch the new switch with your index finger.

Of course, the light can only face oneself; otherwise, it would require two-handed operation, or a rather difficult single-handed operation.

This way, the probability of accidental touches is greatly reduced. Of course, wrapping a rigid strip around the switch button area is also feasible.
