OPERATION: CONNECT THE TELEPHONE LINE TO TEL IN CONNECTOR
THERE SHOULD BE 50V TO 54 VOLTS AT THE TEL CONNECTOR, CONFIRMS THE PROPER TELEPHONE CONNECTION. NOW PLUG IN THE POWER CONNECTOR TO 250V MAINS. ALL LEDS WILL BLINK.INDICATES STANDBY MODE. PRESS ON /OFF SWITCH (SW3) BLINKING WILL STOP AND PLANT ON RELAY WILL BE ON AND PLANT ON INDICATION WILL BE ON.2. PRESS SW1, OFF-HOOK RELAY WILL BECOME ON. THIS IS EQUILVALENT TO LIFTING THE HANDSET OF THE TELEPHONE. AND NOW YOU CAN STORE THE TELEPHONE NUMBER THROUGH THE DIALER KEY PAD. DIAL ANY NUMBER OTHER THAN THE LINE CONNECTED TO THIS DEVICE.IT CAN BE YOUR MOBILE NUMBER. YOU WILL RECEIVE THE BELL ON THE CALLED NUMBER. AFTER HEARING TWO THREE BELLS.PRESS SW1 AGAIN. THIS WILL STOP REINING.EQUIVALENT TO PUTTING THE RECEIVER BACK.NOW THE DEVICE IS READY TO MONITOR THE FIRE SENSORS. ONLY TWO SENSORS ARE PROVIDED WITH THE PROJECT. OUT PUT CAN BE CONNECTED TO ANY CHANNEL TO SHOW THE DEMONSTRATION. YOU CAN BLOW BLACK SMOKE THROUGH THE SENSORS USING AGGARBATTI OR CIGERATE BLOWING. SENSITIVITY OF THE SENSORS CAN BE ADJUSTED BY TURNING THE SCREW TO SLIGHTLY CLOCKWISE . FITTED INSIDE THE SMOKE SENSOR BOTTOM SIDE YOU WILL HAVE TO OPEN THE BOTTOM PLATE OF THE SENSOR TO DO THIS SAME WAY OVERSENSIVITY WILL CAUSE FALSE ALARM ,SO TURN IT SLIGHTLY ANTICLOCKWISE. HOWEVER WE ADJUST EVERY THING BEFORE SHIPMENT. SUPPOSE YOU BLOW SMOKE THROUGH THE SMOKE SENSOR AND IT GET TRIGGERD YOU WILL HEAR SIRON SOUND AND THE RESPECTIVE LED GLOWING AND EMERGENCY LED BLINKING. IF THE RESET SW2 IS NOT PRESSED WITHIN THIRTY SECON.

Intelligent spy robo project has been desighed for the spying purpose .it is radio controlled and can be operated at a radial distance of 50 yards. Many time our army jawan need to venture into the enemy area just to track their activities. Which is often a very risky job, it may cost precious life. Such dangerous job could be done using small spy robo all the developed and advance nations are in the process of making combat robo design, a robo who can fight against enemy. Our robo us just a step towards similar activity. This robo is radio operated , self powered , and has all the controls like a normal car. A laser gun has been installed on it so that it can fire on enemy remotely when required, this is not possible until a wireless camera is installed. Wireless camera will send real time video and audio signals which could be seen on a remote monitor and action can be taken accordingly. Being in size small, will not be tracked by enemy on his radar. It can silently enter into enemy canopy or tent and send us all the information through its’ tiny camera eyes. It can also be used for suicide attack, if required

Wireless Electronic Parrot Doorbell

We can only hope that, should the world ever explode, the only thing left floating in the cold vacuum of space to serve as testimony to our being and all that we have achieved is not the likes of this insanely tacky electronic parrot doorbell that greets visitors with either bird song or up to a six seconds of a recorded user definable message or sample.
Coming complete with up to 20 meters of ‘strong anti-interference’ wireless range and its own integral two watt speaker the Wireless Electronic Parrot Doorbell is battery operated so can be fixed with ease outside your front door or – a somewhat better idea – outside your grumpy neighbours front door in the dead of night.
And if you are desperate to have a tacky, plastic bird hark the appearance of visitors to your humble abode but have a parrot phobia (and, let’s face it, after seeing this who wouldn’t have?) you’ll no doubt be thrilled to know that you can also buy a ‘bird shaped’ (translate as ‘not a parrot’) version – oh joy.
The Wireless Electronic Parrot Doorbell – devised by the same species that conceived of the Theory of Relativity, the Principles of Flight and who gave the Nobel Peace Prize to Al Gore (Mmm) – retails for a mere $21.96 with discounts being offered on bulk purchases.

Electronic Baby Nanny Child Timetable Gadget

Who does not hanker for the bygone joys of extreme youth. After all it’s probably the only time in our lives where we can be truly selfish and do what we want, when we want knowing that everyone around us can either put up with us or we’ll just wait till 3am and then shout the house down. Yes, that’ll teach them.
But wait. What’s this strange gadget that looks like a 70’s themed pocket calculator with not enough buttons?
The answer is that’s an electronic nanny that offers push button timetabling for your young child. Yes, at the push of a button you can program in when its toilet time, feeding time, sleeping time, and so on - and woe betide the child that dribbles before the allotted hour.
Okay, if we drop the flippancy for a moment or two we can see that perhaps the device has its uses, especially if you’re the forgetful sort who not only forgets to feed your child, give him/her their potty-time and so on but is wholly immune to their wailing (or are just too stupid to realise that baby’s crying because its half starving / smelling because its….). But really, any parent who needs to rely on such an electronic nanny to prompt their attention to this degree really ought to spend some time bonding with their child, or reading a book about basic common sense.

1203hrs - Due to a programming mishap baby climbs stairs for no apparent reason whatsoever.

Technology and gadgets that assist with parenting are all well and good – night lights, baby monitors, and so on – but this particular parenting gadget strikes us as verging on complete absurdity.
At least they could have thought of a better name – something along the lines of “The Electronic Anti Neglect Absent Parent Prompter” perhaps?
We would link to the product, but according to our TFTS Post Nanny we’re not scheduled to insert the link at this time.

DIY Electronic LCD

As far as self assembly projects go this DIY Electronic LCD Post-It Note is a frankly brilliant idea and serves to beg the question why a company hasn’t come up with a similar device that can be wall mounted in (say) kitchens allowing you to leave quick notes for your husband, wife or kids – such as ‘We need milk’, ‘Do your Homework’ or ‘I’ve left and I’m not coming back - expect divorce papers in the post’.
The device itself is hardly a project for those uninitiated with home build electronic devices but, with a little patience and the ability to follow rather concise instructions you too could have an Electronic LCD Post-It Note in your home complete with trackpad to assist with posting the aforementioned memos (simply write out your memo with a finger on the trackpad and then, when no longer required, press a button to clear).

Wimshurst Machine

This easy-to-use device consists of two high resistance plastic discs 25 cm in diameter with equally spaced metal sections. The discs are supported with two upright posts and rotate in opposite directions with a hand crank, producing substantial opposite charges which are deposited in the capacitors and on the metal electrodes. You can collect induced charge with the brushes and adjust the electrodes and Leyden jar capacitors for higher potential, thus generating sparks by lowering the system's capacitance. It is mounted on an attractive wooden base. Instructions include theory and background.

Volta's Hailstorm

When near an active Van de Graaff Generator, the tiny conductive balls inside begin to bounce up and down. It looks as if the pieces are "hailing" as they skitter and rebound. The explanation lies in the fact that the floor and ceiling of the cage become electrically charged. The Van de Graaff builds up a charge by induction as electrons are transferred from the ceiling to the floor. Since the balls lying on the floor are now negatively charged, they are attracted by the positively charged ceiling. But when the balls hit the ceiling, their negative charge is neutralized and they become positively charged instead. Down they fall to the negatively charged floor where they become positively charged upon impact. Back and forth, upwards and down - a veritable "hailstorm in a teapot." This flurry of activity will last as long as the Van de Graaff generator is running.
Volta's Hailstorm includes:
Transparent cage mounted on sturdy metal base (9" in diameter)
Ball terminal to attract electric charge
12" high, can be seen from a distance
Tiny polystyrene balls
