Virtual reality and 360-degree video are now very popular consumer-grade technologies. Therefore, everything that can be associated with VR looks very large.
Usually everyone will have nothing to do on the phone to shoot a video to commemorate the beautiful time, but most of the current mobile phone shooting is ordinary video, since you want and VR cheaper, then you must be able to shoot virtual reality or 360 degrees Video only, isn't it?
Then this requires a professional VR camera. For example, Tamaggo, which started on crowdfunding at Kickstarter, is a very useful tool.
From an appearance point of view, Tamaggo's design is like a large "goose egg", can directly shoot 360-degree virtual reality video and photos, but also directly shared to various social media. With Tamaggo, anyone can feel like we are in the same scene.
Tamaggo uses a special design, all the functions are cleverly stuffed into this "goose egg." Tamaggo's ergonomic design allows anyone to operate with one hand and shoot with one touch, providing a true virtual reality video experience.
In addition, Tamaggo also provides an interesting pedestal, so we don't always have to hold Tamaggo in our hands, we can put Tamaggo in the most suitable position, and the close-range vision can be taken into account at the same time.
Tamaggo's lenses feature a patented pixel distribution design that allows the images to be even and undistorted. No matter where the camera is located, it provides a stable viewing experience. Tamaggo's lens aperture is f 2.2. Familiarity with shooting friends knows what kind of shooting effect this aperture can bring.
Even in low light conditions, Tamaggo can still present a perfect picture without visible traces.
Now, Tamaggo VR cameras have begun crowdfunding on Kickstarter with a crowdfunding target of US$50,000. Earlier birds cost US$229 (about RMB1,556), and if all goes well, they are expected to be available in July 2017. goods.
Nowadays, all kinds of live broadcasts are so popular that you don't need to come to a virtual reality live broadcast with Tamaggo, maybe it will make you stand out in the tide of live broadcasting.

The 433MHz, 868MHz, and 915MHz antennas are essential components in wireless communication systems, particularly in the realm of low-power wide-area networks (LPWANs), Internet of Things (IoT) applications, remote monitoring systems, and wireless data transmission. These frequency bands offer unique advantages for various communication needs, making them popular choices among device manufacturers and network operators. Each of these antennas, tailored to their respective frequency bands, ensures reliable and efficient signal transmission over long distances, facilitating seamless connectivity in diverse environments.
Frequency Bands and Their Uses
433MHz: This frequency band is often used for short-to-medium range communication due to its good propagation characteristics in the environment. It's suitable for applications that require low data rates but reliable connectivity over relatively long distances, such as remote sensor networks and asset tracking.
868MHz: The 868MHz band is widely adopted in Europe for IoT and LPWAN technologies like LoRaWAN. It offers a good balance between transmission range and data throughput, making it ideal for smart city applications, agricultural monitoring, and industrial IoT solutions.
915MHz: Operating in the 915MHz band, antennas are commonly used in North America for similar IoT and LPWAN applications as 868MHz. This frequency range provides similar performance characteristics, allowing for efficient long-range communication with low power consumption.
Antenna Types and Characteristics
Antennas designed for these frequency bands can vary in type and construction, but they share several common characteristics:
Design: They can be implemented as dipole, monopole, helical, ceramic chip, or microstrip antennas, among others. The choice of antenna type depends on the specific application requirements, such as size, weight, gain, and directionality.
Gain: The gain of the antenna determines how efficiently it directs and concentrates the radio waves in a particular direction. Higher gain antennas can achieve longer transmission distances but may require more precise alignment.
Polarization: Typically, these antennas are vertically polarized, meaning the electric field vectors oscillate in a vertical plane. This is suitable for most terrestrial communication scenarios.
Material: The antenna elements are often made of conductive materials like copper or aluminum, while the housing or support structure may be made of plastic, fiberglass, or other non-conductive materials for durability and weather resistance.
