Cool, here’s my friend Jason from Hackszine posting about how to disable Lexus and Prius navigation systems. I don’t own a Lexus or a Prius, just a gas-guzzlin’ Chevy, but this might come in handy when I do get one.

Here’s a short video showing you how to do it:

I’ve found that the best way to appreciate the navigation lockout feature is to disable it and see what driving without it is like. The navigation system contains a hidden service menu with a big Override button that lets you do just that.

There’s a secret combination to get to the service menu. The code you use depends on which version of the navigation system you have. They are all roughly the same, so just try them out and find the one that works with your vehicle.

I’ve summed up all the tech blog on Entrecard on SiteHoppin so you can use the following link to “site hop” tech blogs:

We will be doing a special, “Site Hoppin’” through all Entrecard tech blogs and (hopefully) get an interesting post per each one.

Check out this AVR Oscilloscope. Nice hack…

This is one of great project based on AVR microcontroller. It use ATmega 32 as processor and LCD 128×64 pixels for display. If you need to measure low frequency i thought this project, AVR oscilloscope, will be usefull. Maksimum frequency for AVR oscilloscope is 5 kHz (square signal), other signals (sine or triangle) the frequency is lower ( almost 1 kHz) for having clear view of the signal. Voltage input range is 24V AC / 30V DC.

Wow, this has to be the loudest and best solution for you doozers.

Ever sleep-in because your alarm clock wasn’t loud enough? With this design that is guaranteed not to happen! This hack takes a standard cheap alarm clock, some interface components and a fire alarm bell to get the job done right. Normally these small alarm clocks use a piezo buzzer to attempt to wake you up. The alarm signal is hijacked from the clock circuit board and used as an input to the interface board

Tight, here’s some cool hacks on adding bluetooth to your iPod!

1st Ever Bluetooth-Enabled iPod!

If you’re like me, you’ve often asked yourself why Apple has not added native Bluetooth capability to their iPod line up. Even the iPhone only supports mono Bluetooth!

Sure, there are numerous adapters that plug into the iPod’s dock connector to give you wireless music, but they are clunky, they come off easily, can’t use them with your case and you have to charge them separately!

So, here is my way to add “native” internal Bluetooth support to your 4G iPod. The same method may be used with other iPod versions, I leave that up to you.

This is a great idea for people who forget their keys or remote controls, because with this system you are able to open the door up with just the press of a finger onto the sensor which is placed onto the wall.

The Master Lock Smart Touch GDO (Garage Door Opener) is ideal for both residential and business premises which use many vehicles as the system can be used by up to twenty different people.

To open the garage door, all that is needed is a registered finger print to be presses onto it and the door opens, the sensor is waterproof and can work in adverse weather conditions which are from -30 f to 122 f.

Wow, it’s been almost a year since we’ve made some Christmas DIYs. To bring them back to life, we are featuring it here again and well tell you to go make yourself one by following our directions here.

BTW, we are going to go buy a real Christmas tree this year. (Well it’s plastic but not LEDs…)

As you know, the team of moonlighters at Zedomax.Net has been working on new paid wikis. We belive this concept of paid wikis will blow up soon and we have just started diggin’.

We first made Five Dollar Wiki, One Buck Wiki, then EntreWiki.

Now, we introduce you to the new younger brother, The Quarter Wiki where you can buy a page for just a quarter!

That’s right, our motto for this new site is, “In Wiki We Trust”.

We are still working on some functionalities of the site, so don’t blame us if you find a page under construction. We just wanted to let you know heads up on the new website so you can go reserve your pages before all the good ones get taken.

The Quarter Wiki is a new paid online encyclopedia where you can buy your own page for just a quarter.

Unlike Wikipedia, you can add videos, RSS Feeds, advertisements, and GoogleMaps to a page on the QuarterWiki.

More simply, QuarterWiki filters spam by charging a small fee for each page so you don’t have to deal with it.

To get started with QuarterWiki, sign up for an account and search for your desired words you’d like to purchase.

Check out the Part 3 of “HOWTO make sounds with Ardunio” and learn to play melody.

Bit-Banging Sound
To bit-bang sound we toggle an output pin at the desired frequency. To play a musical note, we need to use specific frequencies and play the sound for a specific amount of time.

Generating the desired frequency big-bang style means figuring out what the period or cycle time of the desired frequency is. This is easy to calculate, it’s the reciprocal (1/F) of the frequency. As we found in part 2, 1KHz is 1000 cycles per second. So, one cycle takes 1 one-thousandth (1/1000) of a second or 0.001 seconds (1 millisecond). We need to toggle the pin at this rate so we want to keep it low for 1/2 the time then high for 1/2 the time. Therefore we want to set the I/O pin low for 500uS, then high for 500uS and do this over and over for as long as the duration requires.

Part I and Part II

Here’s a cool audio and video controller DIY using Arduino.

This is the future for all of those unwanted typewriters, yes that is right all those old typewriters that have been abandoned by their owners and left in cupboards and basements are evolving into terminators.

Or maybe it is just a piece of artwork which just happens to use all of the old components from a typewriter that was left lying around, it looks pretty cool and is an excellent use of an old piece of equipment.

I still prefer the first explanation!
