Most of the electronic projects need to use many electronic components to assemble it up and it finally turning into a mess in the very end.

Like the old saying, “Simple is the best!” Due to this old adage, you’ll have the chance to develop a handy yet portable Pin Visualizer. Well, this project is considering as a simple project, as it requires only two main parts here, which are Arduino and TouchShield Stealth!

The Arduino that you’re going to use in this project is an AVR microcontroller board based on the ATmega168. It has 14 digital I/O pins, 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header and a reset button.

Meanwhile, the TouchShield would be a 128×128 pixel OLED screen on a PCB shield. It is an Arduino-ready and can be used to bring advanced I/O capabilities to the Arduino platform. The new version of Stealth Edition has an all-blacked out board, where it looks very slick on top of the dark blue Arduino.

Furthermore, the TouchShield will only use pins 2 & 3, which means it will leave 6 analog pins and 12 digital pins free for other purposes. All of the signals are followed in real-time simultaneously.

After you’ve done with it, it’s time to use it to check your programming work and debug your code easily!

If you’re one of those gameboy lovers and you always have passion want to try something new here, then you’ve come to the right place!

For your information, today’s main theme is how to make an open source gameboy. You must be wondered, “Why should I waste $250 for develop an open source gameboy, instead I can buy 10 used gameboy on eBay easily?” Well, it sounds non-sense to you here, but once you’ve learned how to DIY a gameboy, you’ll be pleased of what you’ve done here!

This Open source Gameboy is an Arduino-based, DIY GamePack is sort of like the Mignon Game Kit, but it is definitely looks much better and cooler. With only $249.93, you can have all these parts: CPU, “inputshield” customizable, vibrating controller, button component, “TouchShield Stealth” OLED display unit, and “MeCap” lithium battery pack.

All you have to do here is try your best to assemble all the parts together and you start the game adventure right away! The only problem is this is still a blank slate with little more than code for a color-changing dot to start with. IF you want to play any games on this new Gameboy, then you’re going to write your very own game codes!

Do you love to watch television programmes when you have free time? Are you a vivid fan of some of the famous television shows or series? Well, no matter you did or did not, as today you will have a closer look on this incredible Super TV-B-Gone gadget!

Some of you here might have seemed this stuff before at other place, but for those that haven’t heard of it before, you should pay attention on this project, because it will need some high concentration here!

With this Super TV-B-Gone, you can turn off TV from a very great distance. First and foremost, you will have to standby 48 IR LEDs and an Atmega8, as you’re going to apply these electronic components into this project! Also, please make sure that you’re buying the 860nm IR LED, as it will have 100 mW/sr, which it’s 70 mW/sr more than the 940nm IR LED at 50mA.

Beside that, you have to arrange the LEDs in 4 rows of 12 pieces and the resistors fit quite nicely between the LEDs. You might also need to use four BD139 NPN transistors to drive the rows. You got to be patient here, as it will take you hours to drill and then solder the board. Let’s do the calculation, 48 LEDs and 48 resistors mean there are total 192 hole plus the other parts!

Even small LED based embedded project can be interesting and worth attention. Check out this nicely made LED menorah that is powered by AVR tiny13 microcontroller.

It is made of nine white LEDs placed on Menorah shaped PCB. Circuit is running from 3V (2AA batteries). Software is written for AVR GCC which basically enables sleep mode after some time. This can be a great gift with some religious pattern.

Well, when you’re being told about this Wave Bubble, what would you think about this stuff? Sorry, you must be wondering that it’s some sort of Bubble maker, but it’s not what you’re thinking here!

Wave Bubble is a self-turning, wide-bandwidth portable RF jammer, which it has a small size, lightweight and easy to be configured feature. This Wave Bubble is having the size of a pack of cigarettes! You can just put in inside your pocket and bring it to anywhere, everywhere you want.

By using an internal lithium-ion battery, it can provide up to 2 hours of 2 bands jamming or 4 hours of single band jamming. The battery is the rechargeable type via a mini-USB connector or 4mm DC jack. Or, you might also be able to use three AAA batteries too!

The output power is .1W (high bands) and .3W (low bands), while the effective range is approximately 20′ radius with well-tuned antennas. Self-turning is being provided via dual PLL, which means spectrum analyzer is no need to build this jammer and a single Wave Bubble can jam many different frequency bands in the same time!

If you want to reconfigure the RF bands, then all you have to do here is plug it into the USB port of your PC and type in the new frequencies when prompted.
