for this project I’ll need pennies my
for this project I’ll need pennies my neighbor Trevor gave me these and I’ll
neighbor Trevor gave me these and I’ll
neighbor Trevor gave me these and I’ll begin sorting them by date I want
begin sorting them by date I want
begin sorting them by date I want pennies newer than 1982 because they’re
pennies newer than 1982 because they’re
pennies newer than 1982 because they’re nearly 98% zinc
nearly 98% zinc
nearly 98% zinc okay I’ve picked out 10 pennies that I
okay I’ve picked out 10 pennies that I
okay I’ve picked out 10 pennies that I think will work so I’ll use this 100
think will work so I’ll use this 100
think will work so I’ll use this 100 grit sandpaper and start sanding one
grit sandpaper and start sanding one
grit sandpaper and start sanding one side of the penny actually this may be
side of the penny actually this may be
side of the penny actually this may be too much work so I’ll try some
too much work so I’ll try some
too much work so I’ll try some double-sided sticky tape and an orbital
double-sided sticky tape and an orbital
double-sided sticky tape and an orbital sander this is working much better to
sander this is working much better to
sander this is working much better to expose the zinc but the adhesive is
expose the zinc but the adhesive is
expose the zinc but the adhesive is melted from the friction and left these
melted from the friction and left these
melted from the friction and left these pennies in a sticky mess no problem I’ll
pennies in a sticky mess no problem I’ll
pennies in a sticky mess no problem I’ll just use some adhesive remover to clean
just use some adhesive remover to clean
just use some adhesive remover to clean them up and now they’re looking great
them up and now they’re looking great
them up and now they’re looking great it’s time to build a battery I’ll cut
it’s time to build a battery I’ll cut
it’s time to build a battery I’ll cut some thin cardboard into pieces just
some thin cardboard into pieces just
some thin cardboard into pieces just bigger than the penny and throw them in
bigger than the penny and throw them in
bigger than the penny and throw them in some vinegar while those are soaking
some vinegar while those are soaking
some vinegar while those are soaking I’ll start my battery cell by placing
I’ll start my battery cell by placing
I’ll start my battery cell by placing one of the pennies with the copper side
one of the pennies with the copper side
one of the pennies with the copper side down on a piece of aluminum foil as you
down on a piece of aluminum foil as you
down on a piece of aluminum foil as you can see nothing is happening yet so I’ll
can see nothing is happening yet so I’ll
can see nothing is happening yet so I’ll blot dry one of my cardboard pieces and
blot dry one of my cardboard pieces and
blot dry one of my cardboard pieces and place it on top this time when I measure
place it on top this time when I measure
place it on top this time when I measure the voltage I’m excited to see over half
the voltage I’m excited to see over half
the voltage I’m excited to see over half a volt from this one cell I’ll add
a volt from this one cell I’ll add
a volt from this one cell I’ll add another penny in cardboard and repeat
another penny in cardboard and repeat
another penny in cardboard and repeat the process until I’ve stacked up all my
the process until I’ve stacked up all my
the process until I’ve stacked up all my pennies now the cells are connected in
pennies now the cells are connected in
pennies now the cells are connected in series and the electric potential has
series and the electric potential has
series and the electric potential has jumped to nearly 6 volts Wow this should
jumped to nearly 6 volts Wow this should
jumped to nearly 6 volts Wow this should be more than enough voltage to drive an
be more than enough voltage to drive an
be more than enough voltage to drive an LED so I’ll test it out with this one it
LED so I’ll test it out with this one it
LED so I’ll test it out with this one it works perfectly and I can’t believe how
works perfectly and I can’t believe how
works perfectly and I can’t believe how brilliantly this lights up just for fun
brilliantly this lights up just for fun
brilliantly this lights up just for fun I’m testing the current draw and it’s
I’m testing the current draw and it’s
I’m testing the current draw and it’s pulling about 170 micro amps I can even
pulling about 170 micro amps I can even
pulling about 170 micro amps I can even light up two at once okay so it works
light up two at once okay so it works
light up two at once okay so it works and it’s actually really impressive that
and it’s actually really impressive that
and it’s actually really impressive that I’m getting electricity from Penny’s but
I’m getting electricity from Penny’s but
I’m getting electricity from Penny’s but now I’m curious to know how long this
now I’m curious to know how long this
now I’m curious to know how long this can last I’ll use some electrical tape
can last I’ll use some electrical tape
can last I’ll use some electrical tape told everything in place and try to fix
told everything in place and try to fix
told everything in place and try to fix these cardboard edges because they
these cardboard edges because they
these cardboard edges because they shouldn’t be touching I’ll do my best to
shouldn’t be touching I’ll do my best to
shouldn’t be touching I’ll do my best to make it airtight to prevent the wet
make it airtight to prevent the wet
make it airtight to prevent the wet cardboard from drying out too quickly
cardboard from drying out too quickly
cardboard from drying out too quickly and then carry it with me for the next
and then carry it with me for the next
and then carry it with me for the next couple of hours to watch for when it
couple of hours to watch for when it
couple of hours to watch for when it dies out okay so now it’s more than two
dies out okay so now it’s more than two
dies out okay so now it’s more than two days later and I really can’t believe
days later and I really can’t believe
days later and I really can’t believe what I’m seeing
what I’m seeing
what I’m seeing the green light is still on which means
the green light is still on which means
the green light is still on which means these little pennies are still pumping
these little pennies are still pumping
these little pennies are still pumping out juice this is awesome so I want to
out juice this is awesome so I want to
out juice this is awesome so I want to try another idea I’ve picked up a

on the bottom is the negative I’m
on the bottom is the negative I’m getting just over 2 volts and 700 micro
getting just over 2 volts and 700 micro
getting just over 2 volts and 700 micro amps so I’ll add wires to the terminals
amps so I’ll add wires to the terminals
amps so I’ll add wires to the terminals and use some more electrical tape to
and use some more electrical tape to
and use some more electrical tape to hold it together time to test it on the
hold it together time to test it on the
hold it together time to test it on the calculator I’ll press the on button and
calculator I’ll press the on button and
calculator I’ll press the on button and it’s incredible the calculator fires
it’s incredible the calculator fires
it’s incredible the calculator fires right up I’m testing out a few functions
right up I’m testing out a few functions
right up I’m testing out a few functions and everything calculates correctly so
and everything calculates correctly so
and everything calculates correctly so now I just need to clean these wires up
now I just need to clean these wires up
now I just need to clean these wires up a bit I’ll chip holes in the casing and
a bit I’ll chip holes in the casing and
a bit I’ll chip holes in the casing and hardwire my pennies into the battery
hardwire my pennies into the battery
hardwire my pennies into the battery leads then tape the penny stack to the
leads then tape the penny stack to the
leads then tape the penny stack to the back a penny powered calculator I really
back a penny powered calculator I really
back a penny powered calculator I really am impressed to how well this worked out
am impressed to how well this worked out
am impressed to how well this worked out and still patiently waiting for this
and still patiently waiting for this
and still patiently waiting for this little green light to die out well
little green light to die out well
little green light to die out well there’s an idea that’s worth a few cents
there’s an idea that’s worth a few cents
