AUTOMATIC SPEED-CONTROLLER FOR FANS AND COOLERS

The first two outputs of IC3 (Q0 and Q1) are
connected (ORed) via diodes D1 and D2 to the
base of transistor T1. Initially output Q0 is high
and therefore relay RL1 is energised. It remains
energised when Q1 becomes high. The method of
connecting the gadget to the fan/cooler is given
in Figs 3 and 4.
It can be seen that initially the fan shall get AC
supply directly, and so it shall run at top speed.
When output Q2 becomes high and Q1 becomes
low, relay RL1 is turned ‘off’ and relay RL2 is
switched ‘on’. The fan gets AC through a
resistance and its speed drops to medium value.
This continues until output Q4 is high. When Q4
goes low and Q5 goes high, relay RL2 is switched
‘off’ and relay RL3 is activated. The fan now runs
at low speed.

Automatic Speed Controller For Fans andCoolers

D uring summer nights, the temperature is
initially quite high. As time passes, the
temperature starts dropping. Also, after a person
falls asleep, the metabolic rate of one’s body
decreases. Thus, initially the fan/cooler needs to
be run at full speed. As time passes, one has to
get up again and again to adjust the speed of the
fan or the cooler.
The device presented here makes the fan run at
full speed for a predetermined time. The speed is
decreased to medium after some time, and to
slow later on. After a period of about eight hours,
the fan/cooler is switched off.
Fig. 1 shows the circuit diagram of the system.
IC1 (555) is used as an astable multivibrator to
generate clock pulses. The pulses are fed to
decade dividers/counters formed by IC2 and IC3.
These ICs act as divide- by-10 and divide-by-9
counters, respectively. The values of capacitor C1
and resistors R1 and R2 are so adjusted that the
final output of IC3 goes high after about eight
hours.

across Mars, conspiracy theorists believe they’ve struck gold: an ‘alien thigh bone’ ha


'Alien thigh bone' on Mars: Excitement
from alien hunters at 'evidence' of
extraterrestrial life
'Normally, I see rocks as rocks,'
said one commenter, 'This can't be a
thigh bone, can it?'
By JAMES VINCENT
Friday 22 August 2014
More than two years into the Curiosity
rover’s lonely trek across Mars,
conspiracy theorists believe they’ve
struck gold: an ‘alien thigh bone’ has
been spotted on the surface of the red
planet.
For keen alien hunters, the image above
- taken by the rover’s MastCam on
August 14 – is proof that large animals
once roamed Mars, possibly even
dinosaurs.
“Simply put this shows that there were
some living things on the Mars (sic),”
asserts an anonymous editorial writer at
Northern Voices Online , while the
popular site UFO Blogger compares the
find to previous images of a “ fossilized,
reptilian spine” and a “ human finger”.
The regularity of these ‘finds’ is of course
testament not to the once-flourishing
wildlife of Mars, but to the human
brain’s remarkable capacity to spot
patterns in random noise.
This was a handy trait for our ancestors
when identifying a potential predator
among the primeval foliage, but in
modern times it’s more likely to lead
only to those little ‘huh’ moments when
we spot a face in some inanimate object .
Of course, there is some truth to
conspiracy theorists’ hopes of life on
Mars, with scientists pointing out last
year that the asteroid impact that killed
of the dinosaurs could have flung rocks
carrying organic matter to the red planet
some 66 million years ago.
Unfortunately, at this point (and for
roughly 3 billion years prior) Mars was a
barren place with no flowing water.
However, if the microorganisms from
Earth had hitched a ride to somewhere a
little more hospitable, like Europa then it
could be a different matter altogether .
