Remove “Password to Unlock Screen” on Android 2.1 Phone


You must have noticed that after you’ve set-up your your phone for Exchange email synchronization, the phone starts asking for a password every time you need to unlock the screen. You must have also noticed that the unlock pattern menu has stopped showing up in the Settings>Security menu. This is because, your phone enforces the Exchange server policy of your company. It’s the exchange server that tells your phone to enforce this security policy. It is indeed reasonable to enforce such policy because you are accessing work/company owned information but most of the time, it is very annoying having to type a password on a QWERTY on screen keypad just to unlock the screen. So I decided to look for a solution.

After Goggling around, i found this very interesting thread about developers trying to disable this annoying “feature”. So I gave it a try and it works perfectly fine on my HTC Wildfire.

I’m pretty sure you want to try it too. You may get the app from the Android market. It’s free. Thanks to the developer.

Got this from

Just search for Market > Applications > Tools > LockPicker

After installing this, you can now disable the exchange password in a few taps. Your phone now has no screen locks in place. The screen is unlocked just right after “Drag down to Unlock”. Now I wanted to re-enable to original Unlock Pattern just to have a little something to secure the data in your phone. Because you cannot find the lock pattern menu in your phone, you’ll a little help from somewhere else.  After another Google search, I found an app called “LockPattern OnOff” by curvefish. You can find this at the market. Here’s the link this is actually just a widget that will enable or disable the lock pattern

Just install the app then add the widget anywhere on the screen. Tap the widget, it will prompt you to setup a lock pattern if you have not done it prior to setting up the exchange email. Then you’re done. Try locking and unlocking your phone.


Just a few hours ago, I was wondering “how can I change the lock pattern?”. There is no menu item that you could select to change the lock pattern. The quick answer is “Pretend you forgot your lock pattern”. :) Sounds funny but it works. Just try entering wrong patterns several times until the “Forgot pattern” button shows up. Then just tap this button then enter your Gmail ID and Password, then you’re good to go. Enjoy!



DIY Airsoft Chrono [PC-based]

Chrono or Chronograph, the term used by Airsofter and Paintball players to refer to the device that measures the muzzle velocity of firearms. This is also called MVMD, short for Muzzle Velocity Measuring Device by the British Army. Muzzle Velocity is the velocity of the bullet as it exits the barrel of the firearm.

A year ago I was an active Airsofter in Iligan who's more interested in modifying and improvising AEGs (Automatic Electric Gun) rather than playing airsoft. I have made my AEG susceptible to high current burns by using locally available MOSFETs. I have improved velocity by replacing cylinder gaskets and spring. I have increased the rounds per minute by altering the armature windings of the drive motor. And most of all, I have made my own cheap alternative PC-based Chrono.

I have posted an artivle before that details the development of my chrono but unfortunately the online forum was hacked/deleted by webmaster of due to some violation in the contents. So, …

Disable PrintScreen on C# without Keyboard Hooks

Yes, there is a simple solution to prevent grabbing information on your C# application screen with the keyboard's printscreen key without using keyboard hooks or calling COM interops. The solution makes use of Windows Forms Message Filter to trap keyboard events on your application window.

To trap keyboard events with Windows Message Filter, you need to implement the IMessageFilter interface and override the member PreFilterMessage(ref Message WM) method. This is the method called whenever a Form receives a keyboard or mouse event. You may want to read more about IMessageFilter.

The problem is that even though you have trapped the PrintScreen keypress event, the captured image will still persist to the clipboard. Therefore the simplest solution is to clear up the clipboard right after the PrintScreen is pressed on the keyboard.

This is how the overridden method will look like this:

publicbool PreFilterMessage(refMessage WM)
Keys kCode = (Keys)…

DIY Mic Shock Mount

For the past couple of weeks I was looking for a cheap microphone shock mount and the cheapest I saw that was available in my country was around US$160 so I decided to build a cheap one. I only spent less than $6 and a 2 hours of my not very precious time.Before I left office today, bought materials and tools to for my DIY shock mount which are a piece of 4”-diameter PVC pipe coupling ($0.50), a set of hair ties($0.40), set of stove bolts ($0.50), a set of coping saw frame and blades ($2.5).First, I decided to cut the PVC coupling so it would look like Rode SM3 shock mount’s frame.Then I used the section of the PVC coupling that was removed to be a attachment brace to the original mic holders base and bolted it to the base of the frame. I had to heat that part so could bend it to a desired angle.And then cut slots on the edges for the rubber suspensions (hair ties). Right after positioning the suspensions, i found a problem. The rubber bands slip every time i attempted to position the…
