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

High Power Vacuum Tube Tesla Coil

These spectacular display devices produce arcs and sparks quite unlike the damped spark gap driven Tesla coils. Operation does not require a noisy spark gap that produces copious amounts of RFI radio frequency interference but operates efficiently at the quarter wave frequency of the secondary coil.
Vacuum tubes while large and requiring filament power do offer robust and forgiving operation and are intended as a good starter approach to solid state Tesla coils. This approach is far less temperamental than the solid state MOSFET or IGBT drivers. However once these devices are debugged and tweaked one can obtain some excellent results. Our lab FET coil generates over 6 foot sparks using only 3 kilowatts. Output frequency tracks within 5% of the resonant point using one our proprietary circuits.
The circuit of the vacuum tube device is nothing more than a high powered Hartley radio frequency oscillator tuned to the resonant frequency of the secondary coil. The circuit uses a medium powered 833A triode transmitting tube that inherently has a high grid to plate capacitance and is readily available. The plate section of the coil is wound with 1/4 inch copper tubing. The grid feed back coil is wound with #16 litz wire. The secondary is wound with #24 litz wire on a properly prepped plastic form.

The output of the oscillator is relatively closely coupled to the secondary coil designed for high Q performance and self resonant to the 1/4 wave of the oscillator frequency. The voltage distribution is now that of a quarter section with a current node at these base and voltage node at the top. Input power to the coil is raw unrectified AC at 3000 volts rms with a current of .5 amps. Peak voltage is over 4000 volts and is supplied by a conventional plate transformer being fed by a voltage adjustable variac for power output control.
