Taffy Pulling Machine
Taffy Pulling Machine
William Gurstelle | Make Vol. 14- 2008 | Pdf | 8 pgs | 3 mb
TWISTED, TUGGED, AND TASTYDownload...
Make a simple mechanism that pulls
delicious candy while it stretches the
limits of multidimensional math.
Sometimes the simplest things have richer histories and
more complex scientific connections than you ever
imagined. Such is the case for the taffy pulling machine.
Taffy pullers manipulate long strands of semisolid, sugary
dough into the delicious, chewy confection called salt water
taffy. After viewing myriad taffy machines in tourist traps
and internet videos, I sought to build one for myself.
Why? Well, when in operation, these devices display
a periodic, repetitive motion so mesmerizing that, when
placed in the front window of a candy shop. they invariably
attract large audiences and pull in customers.

While most civilians wait patiently for electricDownload...
vehicles (EVs) to arrive at their local showroom,
we makers take matters into our own hands. We've
created a dizzying array of street-legal electric
cars, scooters, and motorcycles, and there's even
a National Electric Drag Racing Association.
I wanted to go electric for my own day-to-day
transportation, but I didn't want to reinvent the
wheel. So I researched the existing art, and pur-
chased plans for the "El Chopper ET", a Honda Rebel
250 project that was developed by motorcycle EV
conversion guru John Bidwell.

TV PARTY TONIGHTDownload...
Re-create a mid-1970s video trip by
plugging this box into any TV and audio
source. Beneath the fake wood paneling,
a Propeller microcontroller simulates
Atari's classic music visualizer.
In 1976, Atari introduced Atari Video Music, a plugged-in
music visualizer designed by Pong creator Bob Brown that
bridged the yawning gap between consumers' stereos and
their TV sets. The quirky, psychedelic pixelation device never
caught on, but watching it in action today (search YouTube),
one is taken back to another time, long before iTunes and
Winamp visualizers. It was a time when vinyl, denim, Foghat,
mood rings, limited color palettes, and RadioShack's
business model all somehow made sense.

Evasive Beeping Thing
Evasive Beeping Thing
Brad Graham & kathy McGowan | Make Vol. 14- 2008 | Pdf | 3 pgs | 1 mb
The Evasive Beeping Thing is appropriately named,Download...
since it dutifully does exactly what its name implies:
it sends out a 5-second, high-pitched beep every
few minutes. The source is extremely difficult to
locate because of the way that high frequencies
can penetrate objects and trick our ears.
You've probably encountered something similar in
the real world, such as a failing appliance or a beep-
ing wristwatch buried deep in a couch. As you know,
high-pitched sounds seem like they are coming from
all directions, which makes tracking them to the
source a real chore. Add the fact that the sound only
happens once every several minutes, and it may drive
a person loopy as they spend all day looking for the
source of the sound. Well, that's our goal, anyhow!

Do you like radio-controlled (R/C) cars? Do you like the
desert, but hate the heat? Well, sit down and kick back as you
engage in the excitement of Living Room Baja Buggy Racing.
This off-road competition combines the fun of homemade
R/C cars with the air-conditioned convenience of a fake,
indoor desert landscape - without the big dollar price.
There are no rules, no expensive automotive racing equip-
ment, and a total disregard for public safety (because these
cars are only 6" long and 4" tall).

Here, I'll explain how I incorporated them into

how-to information, it's not a step-by-step guide
to building the complete system. Rather, it's an
introduction to a complex project that could

Perkiraan Nilai sebuah Blog
Anda para blogger, kalau ditanya berapa kira-kira nilai (ekonomis dalam satuan mata uang) blog anda? Bisakah Anda menjawabnya?
Bloggers semua pasti ingat, dalam salah satu butir kesepakatan antara blogger dengan penyedia layanan yang harus dipatuhi setiap blogger adalah blog tidak bisa diperjualbelikan. Namun begitu, mestinya seperti juga hasil karya lainnya, blog walaupun tidak boleh (bukan tidak bisa) diperjualbelikan seharusnya mempunyai nilai.
Masalahnya, siapa yang berhak memberi nilai dan kriteria-kriteria apa yang bisa dan pantas dijadikan ukuran nilai sebuah blog dan bisa diterima oleh setiap blogger di seluruh belahan dunia. Apakah umur blog, contents, nilai page rank, alexa, traffic, index, backlink bisa dijadikan ukuran dan diterima oleh semua blogger. Atau ada kriteria lain, baik secara teknis maupun non teknis yang bisa dijadikan ukuran. Jika memang bisa, apa cocok dikonversikan ke nilai mata uang, atau ada satuan lain yang lebih komprehensif dan representatif. Belum ada yang bisa memastikan apalagi memutuskan.
Jadi belum ada ukuran baku, penentu berapa nilai sebuah blog yang bisa diterima. Kalau ada situs yang menyatakan bisa memperkirakan nilai sebuah blog, pastinya, sangat-sangatlah bersifat subyektif. Seperti 2 buah link ini, http://www.smartpagerank.com dan http://bizinformation.org. Hasilnya seperti di bawah:
Bisa Anda simak dan simpulkan sendiri hasilnya. Sebelum menggunakan salah satu nilai hendaknya bloggers bersifat realistis, karena hanya para bloggers sendiri sesungguhnya yang tahu kemungkinan nilai yang masuk akal, salah-salah pilih bisa ditertawakan orang. Malu deh dong...!?
Mudah-mudahan ke depan ada satu kesepakatan yang bisa dijadikan ukuran nilai blog yang bisa diterima bloggers semua, who knows?.
Bagaimana pendapat sobat bloggers? Untuk menambah referensi kita bersama, para sobat bloggers silakan meng-comment pendapatnya, kalau ada, sekaligus link yang relevan lainnya, sebelumnya terimakasih.

ARTHUR C. CLARKE FAMOUSLY SAID, "ANY
sufficiently advanced technology is indistinguish-
able from magic." In response. modern conjurers
like to say. "Any sufficiently advanced magic is
indistinguishable from technology." At the inter-
section of both maxims sits John Gaughan.
For five decades, he's designed and built illusions
for everyone from Doug Henning to Siegfried and
Roy. Ever seen David Copperfield fly? Gaughan gave
him those invisible wings. Scratched your head
as David Blaine makes a person's watch disappear
and rematerialize behind a shop window across the
street? Gaughan's handiwork in action.

that we have not yet seen the Maker Golden Age. As the
Internet has connected like-minded individuals and the
availability of intormation has exploded, the real catalyst in
the maker movement is the staggering abundance of

Godshot. That's the elusive goal of espresso fanatics
everywhere. Thick with micro-bubble crema and a

the godshot is pulled too infrequently for my liking.
A perfect shot of espresso is the product of many
variables, so anything I can do to lock in one of
those variables is a good thing. Think scientific
method as applied to epresso.
As a home barista, the five factors I worry about
most are: beans, water, grind, dosing, and tamping.
