The Age Old Question, should i go for a TV or fix an overhead projector and screen? Most people still prefer TVs as the memory they have of projectors is that of the grainy images and pull down screens. However, as of early 2020, the commonly available sizes of Large screen TVs in India are
- 75″ QLED/OLED 4k- Which range in the 2.7 Lac to 5 Lac price range depending on the brand and offers available
- 86″ QLED/OLED 4k- Which range in the 5.5 Lac to 9 Lac price range depending on the brand and offers available
- There are some 105″ models available, but priced over 20 Lac.
Where purchasing a projector (4k or otherwise) really makes sense is if you want your viewing screen to be larger than 92–100 Inches; and the difference is especially pronounced once you proceed to larger sizes of screen (135, 150, 165, 180 inches). Most projectors can display a fairly good image for sizes much larger (upto 300 inches).
A good 4k projector with a screen from the big brands (Epson/Sony/BenQ/Panasonic) will work out to be much cheaper than a 86″ Television.
And a good 2k Projector and screen can be sourced for as little as the price of a 65″ TV.

The Raspberry Pi is series of SBC (single board computer) which is designed primarily for educational purposes. Developed by the Raspberry Pi foundation in the US to promote the basic teaching of Computer science in schools. It is a small credit sized single board computer. It can be plugged into your TV and a keyboard that can be used for many of the functions that desktops perform like spread sheets, word-processing, games and it plays high definition video as well.
FEATURES:
- Ultra low cost.
- Ultra low power of 1V.
- Credit card sized, fan less, instant start up.
- It Simple to use.
- It can be called as Fun Computer, mainly used in schools for children to experiments, programming and robotics etc.
- It is inexpensive, simple, open and easy to maintain computers for schools.
- It provides fun environment for experimenting with programming and electronics.
TECHNOLOGIES USED: The Raspberry Pi is based on Broad Com BCM 2835 system on a chip (SoC), which includes an ARM1176JZF-S 700 MHz processor and a video core 4 GPU. RAM was originally with 256 MB and later upgraded to 512 MB. It does not include built in hard disk, but uses an SD card for booting and long-term storage.
OPERATING SYSTEM: To run Raspberry Pi, we an operating system. The Raspberry Pi foundation recommends the use of following OS,
- Raspbian
- A Debian based Linux OS
- RISC OS
- UBUNTU MATE
- Fedora- Unix like OS based on the Linux kernel and GNU programs. Etc..
PROGRAMMING : Python is used as default programming language. Any language which will compile ARMvC can be used with Raspberry Pi.
INTERACTING WITH R-PI: For network access we need a network cables to connect to router. Keyboard and mouse can be connected through USB. We can connect Raspberry Pi to TV or other PC with HTMI cables. If TV or monitor has HTMI cable, it is easy that we can connect by HTMI cable and if a monitor or a TV has only DIV, then we need an HTMI-DIV cable or an adapter. To play audio or video, connect RCA out to speaker or display.
FOLLOWING ARE THE ADVANTAGES OF ZIGBEE:
- Setting up the network is very simple and easy.
- It doesn’t have central controller and loads are distributed evenly across the network.
- It is easy to monitor and control home appliances from remote.
- It will take the place of existing infrared technology based devices. As ZigBee uses lithium battery which lasts long hence it will save cost of battery replacement.
- The network is scalable.
FOLLOWING ARE THE ADAVNTAGES OF Z-WAVE:
- The Z-Wave network installation is simple and easy. If Z-Wave device is once installed, it is also easy to add/remove z-wave devices.
- The Z-Wave devices saves great amount of cost in the battery use as these devices consume less power.
- The home appliances are controlled remotely and this will add to great amount of comfort to the users.
- The z-wave technology based devices are cheaper and affordable.
FOLLOWING ARE THE DISADVANTAGES OF ZIGBEE:
- It requires knowledge of the system for the owner to operate ZigBee compliant devices.
- It is not secure like wi-fi based secured system.
- Replacement cost will be high when any problem occurs in ZigBee complaint home appliances.
- The coverage is limited and hence can not be used as outdoor wireless communication system. It can be used in indoor wireless applications.-`
FOLLOWING ARE THE DISADVANTAGES OF Z-WAVE:
- The coverage is limited and hence requires more z-wave devices to cover larger region. This increases the overall cost if more z-wave repeaters or routers are employed.
- The technology requires knowledge to keep it secure from unauthorized people. This is due to the fact that it is wireless in nature which can be accessed from anywhere and z-wave works on RF.
- It supports limited number of nodes i.e. 232 which is less than 6500nodes as supported by ZigBee standard.
- It supports less data communication speed up to 100 kbps which is less compare to ZigBee.
CONCLUSION:
Mesh networks become more suitable as you add more devices to the network. One Z-Wave network with 30 devices will tend to be more reliable than one Z-Wave network of 15 devices and one ZigBee network of 15 devices. If I had to choose one among ZigBee and Z-Wave, I would choose Z-Wave because I believe that for someone just staring home automation, putting together a highly reliable Z-Wave network will be easier than ZigBee. The Z-Wave Alliance has made it easy to find products that will plug into your network.
This series focuses on which wireless home automation platform may make more sense for your requirement. In part 2, we tackle Z-Wave
Z-wave is wireless communication protocol used primarily for home automation. Z-Wave is mesh network topology. Z-wave automation can be controlled via internet from a wireless key fob, a wall mounted keypad or through smartphones, tablets or computers. Z-wave is considered as mesh topology. Mesh network covers greatest distance even around obstacles. This technology supports four hops between the controller and the destination device. A z-wave network is limited to 232 total devices. It operated at 908MHz frequency band. A z-wave signal can travel up to 330 feet between two nodes in an outdoor, unobstructed setting. However, it gets significantly reduce in the home. Walls and other obstructed combine with various sources of electrical interference to reduce the effective distance. A more accurate guideline for home installation is 100 feet for no obstruction and 50 feet with wall in between. Z-wave has more range hence it tends to be more reliable.
Z-WAVE INTEROPERABILITY:
Z-Wave is a proprietary technology. That means it is owned and maintained by a private organization. The Z-Wave technology is owned and licensed by Sigma Designs. It also runs the Z-Wave Alliance which controls the certification of all Z-Wave devices. The Z-Wave Alliance make sure that every Z-Wave device complies to strict set of standards. The Z-Wave certified controller will work with all Z-wave certified devices. Z-Wave certified products are produced by over 600 manufacture. Each one will be able to plug right into your existing Z-Wave network of devices. If the Door Locks, thermostat, lighting controls and security system are made by different manufactures and if they have Z-Wave inside, they are compatible with one another, it is as simple as that. Z-Wave devices not only communicate with the devices but also communicate with you.
