Its a cardboard box that goes through different chord progressions and plays random notes from them. There is also a servo that thumps the side of the box with the beat.

Video demo of a homebuilt launch controller that's a bit more spiffy than the devices sold on the market. Building howto and blog on www.playspoon****
Dave and Pat break down the basics of RFID technology and how you can use it everywhere.
This is the 3rd test of my RGB LED Matrix. I now have all 3 sets of coloured LED's (Red, Green and Blue) connected and therefore all 192 LED's connected up to my micro controller (An Arduino). The only thing between the Arduino and the Matrix are 4 x 74HC595N 8-bit serial-parallel Shift Registers. Each register controls a seperate bank of colours with the final register multiplexing the common anode rows. The use of the shift registers plus the technique of multiplexing means I only need 3 digital outputs from my micro controller instead of 192.
Code on the micro controller is scrolling my test message demonstrating each of the 7 colours (blue, green, light blue, red, purple, yellow & white) in turn.
Next step is to tidy up the appearance of the font and to write functions to set individual dots, draw lines, boxes, cycle through preset animations, etc. I've also order some 64k EEPROM's to store the font array and animations in.
I have purposely decreased the exposure in the video to bring out the colours.

Model No: 192 With the impending scarcity of many valuable resources, people are now starting to consider other means or sources of energy. While there have been many studies on the viability of wind or water energy, when it comes to an easy transportable energy solution, solar energy is now the major contender since it is the easiest to collect energy from. All you will ever need is a trusty solar panel.
At this point in humankind's existence, most of the energy that many households consume is gathered from the numerous power plants that are then powered by fossil fuels. Fossil fuels unfortunately are nearing their extinction and becoming more and more expensive to source and this is why we're faced with rising electric bills each month. Not only is it an expensive resource, but it also contributes negatively to the environment. The gas that are emitted by the major power plants cause such a harmful effect on our environment that we are now facing a much bigger problem called global warming.
So with all these problems, it is about time to capitalize more on developing energy from the sun. Solar energy is free as the sun is a free resource that anyone can take advantage of. And it is readily available since anyone can have access to it.
The main objective of this project is to track the sun and rotate the solar panel accordingly, to receive sunlight to the fullest extent always during the day time. This movement is achieved by interfacing a stepper motor to the solar panel( a dummy solar panel is given in the project) that changes its direction according to the positioning of the sun. This is achieved using time reference that controls the movement time for 12 hours by a program written in such a way that for every given time the solar panel faces to the sun to generate maximum power which is stored in batteries and future use. This procedure is better than light sensing, as it malfunctions in cloudy and rainy seasons. For more details visit www.efxkits**** or www.facebook****/edgefx
Model No: 193 Using this project we can jam the emerging TV Remote signals on reaching the IR Receiver at the TV end. We send higher strength modulated 38 KHz signal that a normal TV Remote delivers, generated through a 555 Timer in astable mode so that we can jam or stop the TV Remote signals reaching the TV Receiver.

Model No: 204 This project is implemented in such a way that the lights glow according the music. This music operated running lights circuit uses IC’s. The music (sound) signals are sensed by a condenser microphone which is then amplified by an IC. The outputs of the IC are fed to the transistors to drive bulbs LED’s those dance as per the music played. One variable resistor is required for microphone sensitivity and another for maximum performance. The circuit works off 9V to 12V power supply. It is assembled on a general-purpose / dedicated PCB and connecting bulbs for the load the action can be seen live. For more details visit www.efxkits**** or www.facebook****/edgefx
Model No: 209 The aim of the project is to make a low voltage and high voltage indicator. This system will save costly electrical and electronic appliances from the adverse effects of very high and very low mains voltages. The circuit features auto reset and utilizes easily available components. It makes use of the comparators available inside 555 timer ICs. Supply is tapped from different points of the power supply circuit for the display and control circuit operation to achieve reliability.
The power supply consists of a step down transformer 230/12V, which steps down the voltage to 12V AC. This is converted to DC using a Bridge rectifier. The ripples are removed using a capacitive filter and it is then regulated to +9V using a voltage regulator 7809 which is required for the operation 555 timer.

Model No: 213 This is a Precise Charge Controller for Solar Photo Voltaic Panel. The main scope of project is the photovoltaic cells while converting the sunlight in to electricity a charge controller circuit is used. Photovoltaic cells come in many sizes, but most are 10 cm by 10 cm or round and generate about half a volt (0.6 being the PN junction voltage of a silicon diode) of electricity. PV cells are bundled together in modules or panels to produce higher voltages and increased power. A 12-volt module, depending on its power output, could have 30 to 40 PV cells. As the sunlight varies in intensity the electricity so generated usually charges through the charge a set of batteries for storing the energy. Charge controllers comprising of MOSFET are used as power semiconductor switches to ensure cutoff at fully battery charged condition. It also has the provision of overload, deep discharge and under volt of battery protection and the load. For more details visit www.efxkits**** or www.facebook****/edgefx
Model No: 214 The operation of the circuit depends on the astable mode of the 555 timer, which is driven by the emitter current coming from BC109C/ BC548 transistor, since this transistor has high gain. Being in astable mode the IC 555 functions as an oscillator or as a free running mode. To power the 555 oscillator in full operation of the series transistor, it needs to be enabled by a larger current that flows in the collector circuit. This is made possible when the transistor is switched ON by the small current that flows between the base and emitter because of the loop/moisture or wetness sensed by the probes at contact points. On the other hand, the transistor will remain OFF and without any bias during dry conditions.
To control the conduction of the circuit, a switch for ON/OFF state is supplied. The probe contacts should be made of non-reactive metal so that there will be no capacitance or impedance present. It can be achieved by salvaging silver or gold plated contacts from old relays. A cheaper alternative is wiring alternate copper wires. Since the transistor is in emitter follower mode, the impedance at the emitter or the oscillator circuit acts as the current limit so placing a base resistor is no longer required.
