Do you always have the dream to build up your very own games, but you don’t have the natural born talent to do so? Well, with some little help from this Meggy Jr RGB, your dream will come true in just a second!

This Meggy Jr RGB is a new kit, where it allows you to design as a platform to develop pixel games. It is based around a fully addressable 8×8 RGB LED matrix display. Beside that, it features six fat red buttons for the retro feel game play!

The kit is fully driven by an ATmega168 microcontroller, which it enables you to write your very own games or you can control it through the Arduino development environment.

One of the unique features of Meggy Jr RGB is that it is designed to be mounted inside a “handle set,” where it can be a wooden or plastic case. This feature is definitely safer and more pleasant to hold than a bare circuit board!

Furthermore, you can also make, modify and customize your own handle sets to suit your own taste if you want. These are life faceplates in that you can switch whenever you want.

In overall, Meggy Jr RGB is fast, programmable, open source and hackable stuff that is fun to develop!

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.

Most of you here have at least involved yourself with the frequency counter. However, how well do you know about this electronic component?

The frequency counter is an electronic component that is used for measuring frequency and it’s usually measure the number of oscillations or pulse per second in a repetitive electronic signal.

Most of the frequency counters work by simply using a counter that accumulates the number of events occurring within a specific period of time. After a present period, the value in the counter is transferred to a display and the counter is reset to zero. If the event being measured repeats itself with sufficient stability of frequency and this frequency is considerably lower than the clock oscillator being used, then the resolution of the measurement can be greatly improved by measuring the time required for an entire number of cycles!

Furthermore, the accuracy of a frequency counter is strongly dependent on the stability of its timebase. A highly accurate circuit will be used to generate this for instrumentation purposes, and it’s usually using a quartz crystal oscillator within a sealed temperature-controlled chamber, which it is known as crystal oven or oven controlled crystal oscillator (OCXO).
