It runs on a Basic Stamp BS2px code.
Just for fun, it has a big red nose, and the code to drive
it uses pulse width modulation to establish the analog
voltage drop across the jumbo red LED. Only two
connections, Vss and Signal... It has a cute factor,
so how can you resist? It's futile... [noparse]:)[/noparse]

Humanoido:

You are the undisputed, tireless, enthusiastic and inspired champion of the Penguin.

My hero. Clearly, I need to get one ASAP. Where's that "Deal of the Day" button?

Humanoido,

You are one of really few people who can show their talent both in terms of technical knowledge and in terms of imagination.

Please go on with your excellent work.

SRLM

Now, all he needs are some BOE-BOT reindeer to pull his sleigh...

Humanoido

Thanks for the amazing comments. [noparse]:)[/noparse] You'd need nine reindeer BoeBots:
Dasher, Dancer, Prancer, Vixen, Comet, Cupid, Donner, Blitzen
and Rudolph. Penguin seems to have morphed between a Santa
and a Rudolph. Did you calculate the pulling force of nine BoeBots?
I think it's something like (2) * (9) * (49 oz/in) = 882 oz/in. or
about 55.125 pounds of pulling force. SRLM, were you thinking of
going airborne or was this a surface delivery of presents?

Perhaps the BOE-BOT could have an expansion pack: Ornithopter wings...

· Nice work, humanoido.· Will he be in issue #4?

Humanoido

He's in issue #4 on page 8. The Penguin Tech issue
is waiting for completion of another youtube video
and then goes into proofing.

The main key here is the included software. In the project,
Penguin has Aux 5 for a one pin expansion slot. I wanted
to plug in one jumbo LED without soldering in the dropping
resistor, yet needed to control the current and voltage to
keep everything safe. The answer was built into software
with PWM and the provided formula in the article. It's a
kind of virtual dropping resistor, existing only in software,
and a cool concept that can be applied to many other
applications.

If you wanted to apply Da Vinci's Ornithopter to BoeBot,
you'd need to create some rather large wing pairs and
may need to convert to a Super Carrier Board
Item code 27130, to hard wire in the components.
On second thought, convert the Boebot to a Penguin
board and remove the wheels, servos, and chassis to
make a featherweight construct. Let us know the results
of your project. Strictly speaking, you may have better
luck creating an ornithopter Penguin. [noparse]:)[/noparse]

Just updating with some information for Christmas 2010.

Quoting from here:

Rudolph the Red LED Penguin! Get into the holiday spirit with Erco’s
suggestion for a Red LED Penguin with a big red blinking nose. Just plug
a jumbo red LED, short leg to (-), long leg to (s). The idea to defeat use of
a current limiting resistor is by pulse width modulation in software. With
LED on pin 5, code will blink the LED by gradually going from off to an
increasing brightness, then repeat. Duty is a variable/constant/expression
(0 - 255) that specifies analog output level 0 to 5V. It's set to a range from
index 0 to 8, thus creating a voltage drop across the diode from 0 to .2
volt. The volt equation is: Average Voltage = (Duty
