I like to share with RC airplane fan that facing with rudder problem . Often it happen after the RC airplane got crashed.
Here the example of RC Airplane Mustang with rudder problem.
The Rudder "piece holder" strip off and nearly to tear. You have no " piece holder" to replace it.
Take the unused Floppy disk.
1) break the cover.
2) remove the magnetic film media,& cut it to get a small square piece, equivalent size with spoil rudder
"piece holder"
3) rub both magnetic film surface using pen eraser.
4) Apply the foam glue to that magnetic film and insert it properly into rudder "piece holder" position.
Now ,you had fixed the RC Airplane rudder problem.
Have Fun...
Sometime you need to keep your mobile phone in silent mode. Unfortunately the vibrator not work
Here are the tips that you can do to the vibrator function again, but you need to dismantle the mobile phone
Here are my friend mobile phone Sony Ericsson K530i for use in routine job. It 's not vibrate, only ringing.
Firstly,before you dismantle the mobile phone,you must ensure that all setting for vibrate are 'ON'.
Actually the basic function for vibrator are same for all mobile phone.
Using the multimeter , set value to X1 , set the positive (+) and negative (-) probe to the vibrator pin.
if the vibrator start to rotate, it's mean the vibrator are not spoil. try to clean the contact pin.
if the vibrator rotate in intermittent , give a little bit ointment to the vibrator, one drop of eg.WD-40.
or replace with new vibrator. You can buy it at nearest mobile phone repairing shop. Just pay for the part
cost. Save the Labour repairing cost. All the Best. Good Luck
Sometime the mouse that we just bought spoil, usually the wire cut.
If you still 'love' the mouse , you can replace the spoil wire with 'unbreakable' wire.
Prepare the USB connector wire ,hard or soft , it's depend to you. Cut the Female connector.
Remove the wire sleeve.
Open the Mouse hosing.
Refer to the original wire with connector.There are :
1) Green wire
2) White wire
3) Red wire
4) Black wire
5) grounding wire ( just ignore it )
Remove the spoil original mouse wire with the connector.
Keep the board upside down then soldering the new USB connector wire follow the wire color position.
Take note that some USB connector wire have no red color wire. It equal to Brown color wire.
Assemble back all thing and your mouse will run again
This problem happen due to a virus.
Do not format your removable storage, you will regret it.All data will lost
What you should do is.
1. Go to Start Menu > Tolls > Folder Options > View > Show hidden files and folders.
You will see the original folders are hidden
2. Click Start then go to Run
3. type CMD then click OK
4. Command prompt will appear . type > attrib -h -r -s /s /d j:\*.* ( j: is the removeable media name )
then press "Enter"
5. Wait until the command prompt appear one more time. Its mean that the task is completed.
attrib defination:
There are 4 attributes in Windows files:
* (h) Hidden file attribute
* (r) Read-only file attribute
* (s) System file attribute
* (a) Archive file attribute
The general attrib command syntax is:
attrib [+r|-r] [+a|-a] [+h|-h] [+s|-s] [d:][path]filename [/s] [/d] [/l]
Create your own DC voltage tester by using a damage AC Test Pen.
Here, I am using a small size of test pen. Sorry, I am forget to snap a photo at the beginning of project.
The above figure, show how I do the connection.
1. 1K ohm resistor are to avoid L.E.D burn out.( soldering to Fuse cap )
2. 2 pieces of L.E.D ( soldering to fuse cap ,tip to tip )
3. Soldering 1 wire to negative ( - ) point ( through small hole at the test pen Holder )
How to Check the L.E.D polarity before soldering it ?
1. Using the Multimeter , set the value to X1 as shown above.
2. Check the L.E.D, connect the positive (+) and negative (-) multimeter probe to L.E.D lead.
3. During the checking,if you found that L.E.D is light on, it's mean the probe (-) is L.E.D positive (+) point
and the probe (+) is L.E.D negative (-) point
Here are the Completed negative wire connected as negative (-) point
Now, this DC test pen are ready to use for any dc12 volt checking wiring such as for vehicle repairing,etc.
Don't throw away your expensive flash light if it can't
switch on, it could be happen after the Flash light drop on the floor or after
heavy usage ( on/off )
If the problem remain unchanged after replacing new battery, you need to
dismantle the switch compartment
What you need is a tweezer , put it into the two hole of switch compartment
then turn counter clockwise
Finally ,you will get all thing come out
Take the main on/off switch and spray it using WD-40 or Perfume , DO NOT spray
it using CONTACT Cleaner , you will regret it. Some chemical will harm a
plastic.
Assemble back the switch compartment and batteries, your flash light will
work again.

Identify - The System
Errors & Symptoms
This is some functionality
symptoms that your system will display if your PC capacitors are spoil. Please take
note that these symptoms can occur even if your PC capacitors are not spoil.
System Faulty:
Often or Permanently Blue
screen
Memory Test Failed even had replace the RAM card
Fail to Booting even had repair the OS
Stucked at half way during reinstalling OS
System randomly and frequently Hang up.
I like to share with you how to fix the PC problem regarding bad capacitor.
This step only can apply, after
you had check all OS and other device then finally you found that some of capacitor
are swelling.
Refer the red arrow, you will realize the capacitor swelling.
Actually ,this is a basic repairing of capacitor replacement, no matter what
is the MOBO type, if you are lucky. The MOBO will function back as normal
condition.
You need the Tools:
1) Soldering Iron & Solder Lead
2) Soldering Sucker or Solder Wick
3) Desoldering machine
I am very sure that you know the Soldering Iron, but its better if you using
the Desoldering machine to avoid
the MOBO copper track strip out.
This is the Desoldering machine to suck the remain solder Lead & to
Soldering the replacement capacitor
This is the view after remove the bad capacitor .Firstly you need to ensure
the capacitor pole , (+)positive & (-) Negative. Refer the red arrow.
The capacitor have
only 2 pole , you can see the (-) by one side line with - mark, and don't
solder it at wrong pole. it will not function or will become a fire cracker
once you switch on the PC.
And you must replace
with same voltage and value for the capacitor, eg: as above 6.3v 1500uF
