The most important part of a school`s CATV-CCTV system, is the process of planning for its infrastructure and the actual plan itself. The schools planning ideally is best facilitated when it involves all the school`s role groups as well as the district and state telecommunication specialists. The following three diagrams Measuring, Backbone, and C

omplete Plan are part of the CATV-CCTV plans for Kailua Intermediate School that were designed by Harry Uchimura and approved by Ron Sodetani of Network Support Services Branch (NSSB). There are enough schools who have installed their system backbone that can give you recommendations for contractors to help you with your project. Ernie Lum of Ernie`s Cabling is one of the best licensed contractors for a fair price, reliability, honesty, accessible, and guarantees his work. Cabling can be purchased from Oceanic Cable, Hawaiian Tel/GTE and Mauka Cabling Co. Most schools have had good service from Oceanic Cable and from Mauka Cable. Hawaiian Tel/GTE are challenging to work with. This varies with the size of your project. Kailua Intermediate School spent approximately $7, 000 for cables and the materials needed to install the TV backbone system for the entire campus which has about 97 TV connections. Harry Uchimura from NSSB will terminate the cable and connect the purchased materials from the cable drop from the street to the school`s LAN, usually in the library or media center area. Schools may contract outside vendors such as Oceanic Cable which will not be serviced by NSSB if there are problems with the installed system. Harry may be contracted on the weekends. Assuming that the backbone is already in place, a school that has approximately 100 boxes to install and terminate plus install the materials on the ordered list, a...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
