Crocodile Jakeman

I decided to take a break for awhile and went to hunt crocodiles.  This Puk Puk (pictured below) was used by a sorcerer to capture or should I say devour the child of a neighbor who allegedly had a confrontation of foul languages with the old sorcerer.

I call him “cradle snatcher” and he was found in the Wagol River that runs by Kerema Compound in Madang.

Kerema Compound in Madang was a piece of Land at Pain Damon Point on the other side of the bay from DCA compound and Admin compound on the other side.  It was in the Early 60’s when the piece of land was provided for the builders of Madang Town.  Mainly Kerema carpenters and builders.  A few settled in and liked Madang so much that they didn’t go back to their home in Kerema.   

After 40 years there is a new generation of Kerema blong Madang (Original Kerema born in Madang) wave of people.   The Elderly folks a slowly passing away and the youths are still thriving. 

  It is saddening to see the once peaceful Kerema Compound that provided safety and a haven for the builders of Madang Town, has become a hide away for notorious theives and unlawful youths who take advantage of the poor and neglected basic services to brew and consume Yawa or Steam (Home made alcohol) and then causing fear and terror to the homes and livelihood of the simple Kerema people of Madang.

Ave lea soso.

Below are some more pictures of the happy lives who live at Pain Damon Poing, Kerema Compound.

Cabling Wide Area Networking (WAN)

A wide area network (WAN) is a computer network that covers a wide or broad area.  It’s like communicating from Madang PMIZ location at Vidar to Tabubil in the Western Province.  D-Link ANT24-1400

Other computer networking that are complimented by WAN are PANs, LANs, CANs, or MANs. Did you get all that down?

These are also computer networks but are restricted to a room, building, an area or a city.   

WANs are used to connect LANs (Local Area Networks) and other types of networks together, so that users and computers in one location can communicate with users and computers in a different location.

Many WANs are implemented for one particular organizations or business and are normally private and others, built by ISPs or Internet Service Providers like Daltron, Datec, Pacific Mobile Communications or Digicel provide connections from an organization’s LAN to the Internet.

WANs are often built using leased lines.  A leased line is a symmetric telecommunications line linking two locations. At each end of the leased line, a router connects to the LAN on one side and a hub within the WAN on the other. It’ expensive but can reach speeds greater than 156 Mbps.

Leased lines can be used for telephone, data or Internet services. Typical communication links used in WANs are telephone lines, microwave links & satellite channels.

Instead of using leased lines, WANs can also be built using other methods that cost less like circuit switching or packet switching methods. Network protocols including TCP/IP deliver transport and addressing functions. Protocols including Packet over SONET/SDH, MPLS, ATM and Frame relay are often used by service providers to deliver the links that are used in WANs.

Transmission rate usually range from 1200 bps to 6 Mbps, except for ATM and Leased lines which can reach faster speeds.

I hope this will help you with the idea of WAN.  By the way….PAN stands for Personal Area Network, CAN for Campus Area Network and MAN for Metropolitan Area Network.

Diagnosis:

-Continuity check on fuse with multi-meter. OK

-Voltage trace from AC supply through fuse and across current sensor resistor. Discovered zero voltage after resistor.

-Ohms check on resistor. Opened. Continuity check. Open.

– All other major components like large filter caps, FET and transformer primary windings checked ok.

 

Fault:

Sensor Resistor 0.5Ω opened during high power surge caused by power black outs.
