They say that if you are on a desert island for so long, you will be able to make almost anything out of coconuts and here is the proof.

This is a really cool coconut amp, and in fact if you can make this then you are on your way to building up a civilisation.

Check out the Atmel AVR temperature controller hack, although I made a better one last year that can be controlled via ethernet, the case looks awesome!

Wine doesn’t like subzero temperatures, and during wintertime, my “winecellar” got pretty cold.
There was an electric heating element, but the thermostat was broken, so it was either full burn or nothing.

That’s how the temperature monitor/controller came to be.
It was an obvious task for a small processor and I’ve always wanted to test the Dallas temperature sensors.

So, I designed this little device which could monitor the temperature and control the heater.

Researchers at the Oklahoma State University and DARPA have developed something that can only described as a mini jet engine, it can vary in from being smaller than a cigarette to longer than a foot, but can provide power to a UVA or other un-manned craft, which can take video or other images of the enemy.

This is a great time for this type of technology as there are many other items coming out such as the un-manned UVA that can stay in the air for up five years!

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…)
