the population of Earth has risen
continuously since the Great Famine and
black death in 1350 with numbers like
these it's no wonder the Tooth Fairy is
getting behind I decided to take matters
into my own hands and figure out a
system that ease the burden on the tooth
man
if we can send our teeth directly to her
she won't have to spend the time
visiting each of our homes blocking the
budget to build an aerial delivery
system I settled upon a more traditional
method of material transport pneumatic
tubes with a shop vac and some PVC pipe
I designed an inexpensive system for the
conveyance of lost teeth to the tooth
fairy's treehouse using valves a t10 to
control the direction and remote
controlled vacuum in the Attic building
a two-way system is simple let's get
started since I'm not yet sure where the
Tooth Fairy lives I built the first
version of the system with a station in
each of my two sons rooms a pipe from
the vacuum runs to both stations and
manually operated valves determine where
it pulls I chose inch and a half pipe
because it was a good size to run
through 2x4 walls the pipe in which the
carrier travels runs alongside the
vacuum pipe but has smoother turns this
flexible PVC creates gentle curves that
won't snag the carrier
our carrier capsule is a one ounce
travel bottle that fits well in the pipe
with a single wrap of velcro it happens
to hold a lego mini think which the
Tooth Fairy may want to send in exchange
for a tooth for each of the sending and
receiving stations we need a way to load
the carrier bottle into the transport
pipe and reseal the pipe these are pair
sleeves will act as the door to admit
the carrier a chunk of PVC sheet will
act as a barrier between the vacuum
pipes and the transport pipes so the
carrier stops in the right place when
the vacuum runs this little vacuum will
live in the Attic and be controlled by a
Raspberry Pi in a power switch tail I
threw together a couple locking doors to
prevent unauthorized access to the
stations to operate the system we use
old iphone stockton each station
commanding the Raspberry Pi with a web
interface over Wi-Fi instead of buying
fancy docks I just glued a couple old
cases in place let's give it a test
can you tap on tooth fairy put the
bottle in there hit the bottom button
that's awesome high-five yeah I'm gonna
go check on I mentioned we don't yet
have the system connected to the Tooth
Fairy secret treehouse so the carrier
just goes from one station to the other
since the whole family gathers at the
sending station during events the boys
don't notice at some point during the
process one of the parents steps out
sneaks to the other station to swap the
contents of the carrier and prepare the
other station to send it back
is it ready to come back okay it says we
should set this pal here and the closes
can you close that there you go okay
engage pneumatic power
let's all help out the Tooth Fairy and
get started on your pneumatic transport
system today
