Mte Projection

“Confidence is knowledge of yourself.”

Here’s my definition of confidence, which leads to how you can build your confidence: “Confidence is knowledge of yourself”. When you have done something well a hundred times you have built knowledge in your ability and therefore you won’t think twice about doing it again. This lack of contemplating how to perform a skill is because you know your ability and are confident. Building confidence, then, is to have knowledge of doing something well.

Building confidence can be done in a number of ways. The traditional way is to try, fail, try, learn, try, succeed… in other words, keep trying until you perfect it. Most confidence is built by doing something repetitiously. Another way is to borrow confidence from the future. Try this exercise to see what I mean.

1. Choose something you’re not confident in doing today (e.g. public speaking, a new sport, etc)

2. Project ahead in your mind to a future point in time when you’ve mastered this task (e.g. a month, a year, etc)

3. In your projection think about the knowledge you’d have about that skill and try to sense the confidence you’ll feel in the future when performing it.

4. Now borrow that future sense of confidence and approach learning this new skill with the knowledge of having mastered the skill in the future.

If you practice this projection technique you’ll find that you can borrow some or all of your future confidence and accelerate your growth and mastery of your new skill today. Of course there is no substitute for actual practice but a little extra confidence will greatly boost your acquisition of confidence and knowledge of yourself.

LED fault causes

I've been introduced to the world of LED lighting. During the past two weeks I received two lights in a undisclosed (but very popular) distributor in Hong Kong .

These lights are called budget of high value but both have been "tics." The first (Romisen RC-F4) had a problem with the switch to be informal. The second (MTE "P7-D, 5-way) had a flicker problem. I am sure that others have problems with the lights of the budget, and therefore I made this little guide to solve problems. Feel free to comment that I am a noob about LED flashlights (with the exception of a Luxeon I bikelight I designed and built for an engineering project in college a few years ago).

OK! Here goes!

my lights

These are the lights I use today (I have a DX Pig-light, but I've never had any problem with it, and rebuild these are maintenance-free, ha, ha), the Romisen RC-F4 and the MTE "P7-D" (5 – Mode).

DIM OUT

1) Check the batteries!
If the output is tenuous, but there is no question of blinking, the battery is a likely culprit. Some voltage regulation circuits may also flash when falls voltage, but this is rare. Remember: If your light uses more than one battery has to be extremely careful not to mix and match batteries of different capacities or voltage. If you suspect that one of the batteries are dead (sometimes even brand new ones are dead) remove and get checked. This goes for all base Lithium batteries, primary and rechargeable batteries. Consider buying also protected cells.

2) Verify that the LED

Visually inspect the LED to see if it shows any sign of being "burned" (discoloration, dark spots). This should be visible through of the lens.

3) Check the solder points and the contact-points

Visually inspect the weld by removing parts of the head. If this is not possible to remove the bezel and remove the glass and mirror if possible. Some heads are attached (such as MTE "P7-D") but can still be possible to access the LED / pad to remove the bezel / lens / reflector. Be very carful touch the reflector. And polished aluminum is soft. If you do not know what you are doing the cleaning, is likely to ruin! Clean the lens when you reassemble. If everything looks good, continue troubleshooting using the action on with blinking / switch issues.

FLASH / SWITCH ISSUES

1) Clean the internal light
Use compressed air or "the key and blow" to ensure no metal shavings or debris from the manufacture of parts detected metal inside the tube.

2) Check the contact between the body and tail cap switch-assembly

Remove the back cover and the use of a clip or a piece of metal otherwise proper and contact between the battery negative and the body. Be sure to contact a part of body that is not anodized. If it stops flashing, which may indicate a "bad" switch or bad connection between the cap and the body. Use tweezers fine-tip (or a sturdy pair of pliers) to tighten the switch and the assembly (turn clockwise). If the switch and the assembly is difficult in the back cover, remove (Combating clocwise) inspect.

Some switches are "open" (MTE "P7-D"), while others are "closed" (Romisen RC-F4). If your switch "closed" type, will be held on the switch a container that is inserted into the back cover. If it is "open" the back cover the actual shape of the container.

For "closed" switches, press the inner seal (see photo), reassemble and test. If there is no improvement, continue with the procedure of "open" switches.
To "open" switches, remove items and check the contact. Use a fine grit paper (400 grit or higher) to clean the contact surfaces of the solder flux and other impurities.

Reassemble.

3) Check the contact between the body and the pill.
Try paper-clip as described above. Vary the pressure on the battery. If blinking is reduced or stopped when pressure is applied, indicating a problem of contact between the pad and the body.
Get access to the pill by removing the head, or by removing the bezel / lens / reflector. Remember to touch the "bright" parts of the mirror with your hands (or anything fat)

Check if the pill is adjusted using a pair of tweezers / needle nose pliers and turn right. If it is tight can be a problem with wiring, which requires a repair (perhaps to be covered in another thread).
Reassemble and you're done.

I hope this is helpful. I searched these forums for help on my MTE "P7-D" as it was almost useless when I got it (flash heavy) and had not Easy Check-list to solve these lights. Here it is! Feel free to comment!
