Arduino Flush-Less (Version 1.0)
California is suffering from a debilitating drought.
When hasn't it, am I right?
Convert grass to gravel and ficus to cacti are all proposed options.
The absolute solution?
Desalinization pla--er, I mean, stop pissing away water!

Standard toilets use up to 6,500 mL (1.6 gal) of water to flush
a standard person's 400 mL of urine twice a standard day.

Hack most existing toilets with the Arduino Flush-Less
and reduce waste by up to half with out replacing a single toilet.

With just 1,825 AFL units installed, we could save 1,000,000 gallons a year, exclamation point.

Did we mention Arduino Flush-Less (Version 1.0) is BlueTooth enabled?!

Despite the plethora of HackADay logos ala our futile attempt for favoritism amidst our submission unto the HackADay Prize-contest, the Arduino Flush-Less and TV Miller are not affiliated with HackADay or their unscrupulous, dubious, down-right-under handed ways. Heathens.

All claimers about HackADay are untrue, unless other wise true, to which, see?!

Currently in development is our Project AFL, for submission in the HackADay Prize contest. There are two methods to follow along with all the lack of action. Follow @TVMiller for real time updates which will include the occasional lambasting of another culture or book mark on HackADay's project repository or what ever one might identify it as. Stay tuned to further updates on this project as we seek to automate for efficiency by hacking the naughty bits depository.
Formerly HLTBAL1 due to budgetary restraints, HLTSCT4X is a ground based rocket launch utilizing an experimental propulsion. It performed precisely as predicted.

FleshliPad Becomes Fleshlight LaunchPad
What was once a novelty engineering project, today has become what will certainly be an evolution of the medium of electronic interactive adult entertainment and subsequent gratification.

Three years ago, we pitched a product design to an executive at Fleshlight d.b.a. Interactive Life Forms. Less than a year later, it manifested in to a viral sensation, pun intended. The FleshliPad was chortled in discourse on programs like Playboy Radio and featured in gadget blogs to the likes of Gizmodo. It became a hypothetical global perv-nomenon.

The highly anticipated apex of this journey now cedes. Earlier today, Fleshlight released the following advertisement on YouTube which unveils their new product, the Fleshlight LaunchPad.

We here at TV Miller applaud it's finality and tip our hat with an affable watch yer top knot.
Resistance Theory (Pass 0.1 Sample)
Simplified for documentation, the upper diagram is a standard model theory of a photon transit via absorption and expulsion. The lower diagram is a two-dimensional spherical wave with oscillation disturbance transit and supplementary wave pattern representation under lay. The Resistance Model demonstrates wave field resistance nodes (particles) and subsequent containment prior to demanding frequency change, suspended in a three-dimensional compression mass.
