The Peripheral Tunnels Propeller

This is my current main project:

The Peripheral Tunnels Propeller

Peripheral Tunnel Propeller Cutaway

This is an Ultra Quiet propeller I invented, Its based on my disclosure of the principia that fluid inside barrels could be accelerated with the minimal turbulence due parasit flows.

This project is on PATENT PENDING.

The Following is a more formal Abstract of what is, and how it works:

Quiet Propeller Design Disclosure, which consists on a Barrel drilled with spirals Peripheral Tunnels..

It main feature is Quiet Operation, this is achieved thanks to the minimal turbulence induced by the tunnels while accelerates/decelerates the liquid or gas, also due the high strength of the device which near cancels torsional flexions, avoiding to generate noise.

Other design’s goodies are:

Allows build on exotic materials for a Propeller, as Ceramic, thermoplastic, Aluminium. Honey-Comb composite, and a combination of both, much more.

Easy mass-production with current well known techniques and modeling tools, at any size scale and any production volume.

Inherent Safe operation, the external barrel shape, doesn’t present edges that hooks or cuts surrounding objects, animals or people, also the inner’s propeller intakes may be easy protected with minimal performance degradation.

More reliable and durable, the inherent high strength and the circular shape minimizes the damage that impacting object can do, allowing easy survival to impacts that easy would to destroy a bladed propeller.

Here is in more Detail a PDF that contains the Non-Provisional Patent Application at USPTO:

Forgive / Detach

One who is sure of his power can forgive without fear, as one conscious of his transitoriness can understand detachment.

o

Aquel que esta seguro de su poder puede perdonar sin miedo,como aquel consciente de su transitoriedad es capaz de comprender el desapego.

Mini Linux Box as Media Center – TimeMachine – Wireless Router

Few Months Ago I owned a Zbox Nano as Media Center / TimeMachine Backup Server and Wireless AP.

What Does this little box for You ?

XBMC including features:
- Media Centre / Home theatre.
- AirPlay Server (display videos/audio from iOS devices).
- DLNA Client/Server.
Torrent (Transsmission Host / Remote).
TimeMachine Server: Allow Apple Devices to Backup and Share Files (also on plugged media).
Wireless AP: Allow to share Modem/Ethernet Internet Access and to Access the Server Wireless (with Strong WPA2 Protection).
Full PC Functionality (Ubuntu).
No Display Needed to access Server Features.
Stand Alone Access to Server Features (Airplay, DLNA, TimeMachine), no Network/Router Required.

Nice Features for a sub-300$ Box…

I Wrote some Shell Scripts, for the zBox (AMD-ATI version), not difficult to adapt for other platforms.

You will need an micro PC (Zotac Zbox, Acer Revo,Asus EeeBox,Foxconn, mini-ITX),512MB RAM 4GB USB Drive (empty, formatted), Strong Internet Connection.

First, Download Unetbootin http://unetbootin.sourceforge.net/ then Create an USB Key Installer for Ubuntu 12.04 LTS -this guide is for LTS version of ubuntu, to get Strong Stabillity and support).
Then Install Ubuntu using the USB Key.
Download the following Scrips and files to your ubuntu User /Home Directory (keep file/directory structure).
- https://docs.google.com/folder/d/0B9WBNyeUBu5oUmMxNEF1RTlDVDA/edit
Open Terminal and run every script (will ask your password for Super User Privilegies), like this: $> sh .iServers.sh
- those scrips are named on it purpose, most can be used independent to achieve it goal (as the iServers to install TimeMachine functionality). Prior Install XBMC, run Optimize APU, then iXBMC.sh then iRemote.sh .
Optional Debloat.sh will uninstall features I think are useless on a MediaCentre Box.
Resetwireless.sh will allow you to change SSID and Password on the Wireless AP feature.
APU optimization is Intended for Zotac zBox (AMD APU), among Optimized driver install, and other optimizations, it will repurpose the power button to use to safe unmount removable media, If you will use it on another hardware platform read carefully and do research on what to do on your platform to do the same.
iWireless.sh is intended for hardware compatible with HostAPD see: http://en.wikipedia.org/wiki/Hostapd of course it’s optimized for zBox hardware so you may (rare) need to optimize it, specially if you want to use 5ghz band.
