Arirang (Korean: 아리랑) is a line of North Korean Android smartphones. They were announced on 10 August 2013. The phone was distributed to local sales points operated by mobile operators such as Koryolink to be sold together with 3G SIM cards or as a stand-alone device. It is named after the "Arirang" Korean. . In 2013, toured a factory called the "May 11 Factory" that makes the "Arirang" . In the August of same year, first Arirang was released and was claimed to the first domestically produced smartphone. . • • • [pdf]
North Korea's government only allows its citizens to use smartphones it created to monitor and control them. While we can't get hold of them here, there's plenty of information available that gives us a fascinating look into the world of North Korean smartphones. Smartphones were introduced to North Korea in 2002, then banned from 2004 to 2008.
The new report catalogs 55 smartphones that have been sold in North Korea, with specifications and other information where available. View and download a copy of the full report at Lumen. In this new report, Martyn Williams examines smartphones, the smartphone market, and wireless networks in North Korea.
One trend noted in recent years is that North Korean smartphone brands appear to have begun offering several versions of a phone with differing specifications. This mirrors the strategy of companies like Apple and Samsung with their flagship products.
These smartphones from North Korea are more than just messaging devices; they act as systems for oversight. Two built-in applications called ‘Red Flag’ and ‘Trace Viewer’ guarantee that the state monitors all device activities. The program Red Flag observes the phone software to stop any illicit changes from happening.
Recent reports say digital payment apps have also been enthusiastically adopted despite their potential for additional surveillance of citizens. One trend noted in recent years is that North Korean smartphone brands appear to have begun offering several versions of a phone with differing specifications.
A glimpse of a North Korean phone with a built-in mosquito repellant. There's also a Google Drive icon that opens a screensaver app. It's hard to confirm these phones' details reliably. Some specifications here are sourced directly from the DPRK state media, so take those with a bucketload of salt.

The function of the diodes is to keep the power flow going in one direction, and prevent power from feeding back into the panels when. [pdf]
A PV junction box is attached to the back of the solar panel (TPT) with silicon adhesive. It wires the (usually) 4 connectors together and is the output interface of the solar panel. How to connect the solar panel junction box to the solar array? With the use of a junction box, it becomes easy to connect the solar panel to array.
Usually, this means orienting the solar panel toward the equator or the direction that gets the most sunshine all day. You then have to attach the internal wiring of the solar panel to the terminal blocks of the junction box. Once you have placed the internal connections, you can connect the junction box to other panels or the main power system.
With the use of a junction box, it becomes easy to connect the solar panel to array. Usually cables with MC4 / MC5 connectors at the end are used. A good junction box keeps corrosion at the terminals to a minimum, as it will exclude water coming in. When purchasing solar modules, always have a look at the IP rating of the PV junction box.
The connection box is a central hub. It joins the parts and makes electricity move freely. The solar panel has photovoltaic cells. They make direct current (DC) power when sunlight touches them. The internal wiring of the connection box then receives this DC. In the connection box, the busbars split the current.
A photovoltaic (PV) junction box is an important part of the solar panels. The junction box is an enclosure on the module where the PV strings are electrically connected. The majority of junction box manufacturers are nowadays based in China. How is the junction box connected to the solar panel?
To sum up, a box for solar panels is a crucial part of a solar panel system. It offers connection, protection, and optimization capabilities that are essential to the system’s efficient and secure functioning. To get the most out of your solar panel system and extend its lifespan, you must understand the significance, parts, and operation of a box.
