Modern smartphones have taken over a lot of functions of other devices: cameras, recording devices, music players etc. Now, however, there is a device that aims to take back the camera function from the smartphone. Basically, this device, known as FrontRow, was built to recover the simplicity of mobile technology. FrontRow is a tiny, coin-sized device with two cameras, an 8MP camera at the back and a 5MP camera in front. The device shoots video in 1080p, and it can also stream to Facebook or YouTube for up to two hours.
According to the creators, FrontRow should be worn around the neck like a medal, with the rear camera facing out. It also has a little touchscreen, where you can view your captured content. Also, apart from the photos and videos you can capture with the device, you can also capture photos and videos and stitch them together. This Story Mode also makes use of sensor data and some other info to cut out the poor parts of the captured content.
The creators of the FrontRow camera pendant, Ubiquiti, expect that people will want to wear the device all the time, so as to capture pictures and videos more easily. According to Joe Santucci, the product director of Ubiquiti Networks, all the constant distractions brought about by notifications tend to take attention away from the actual act of capturing photos and videos. Therefore, the company produced something really accessible that could document a whole day without any video edition, for example.
FrontRow does seem like a device that would catch on with a lot of people. However, Ubiquiti needs to find a niche where the idea of the pendant camera would work. For example, tourists might find this device useful. Also, people in places where camera phones are not convenient or not allowed might find a good use for it. Until the device becomes popular, however, most people will probably stick to their smartphones.

The exhaust gas recirculation valve, or the EGR valve, is a small component in your vehicle designed to allow the flow of exhaust gases into the intake manifold in small amounts. This is a simple valve that opens and closes when it needs to. This is either to let exhaust gases into the combustion chamber, or to close in order to prevent the gases from entering. Now, when the car engine comes on, the valve is turned on too, and it stays in a closed position.
Once the engine crosses a certain temperature threshold, the EGR valve opens and lets the exhaust gases combine with the air-fuel mixture in the combustion chamber. When the engine is turned off, the EGR valve closes too. Now, an EGR valve can fail in two ways. It could either fail to open, or it could fail to close. Here are the symptoms of a faulty EGR valve according to the manner of failure.
An EGR valve
IF THE EGR VALVE FAILS TO CLOSE
This will let in exhaust gases to the intake manifold continuously. The effects include the following:
- Increase in fuel consumption.
- There will be an odour of fuel in the air while operating the vehicle. This is due to the increase in hydrocarbons leaving the vehicle.
- When the engine dies, there could be stalling.
- The engine could be idling roughly when you start it, or when you are at low engine speeds.
IF THE EGR VALVE FAILS TO OPEN
This blocks the exhaust gases from reaching the intake manifold. Here are some effects of this symptom:
- After the normal ignition, there could be a second ignition, and both could combine to cause serious damage to the engine.
- There could also be tapping or pinging sounds coming from the engine at low revs-per-minute (RPM). This is the sound of early ignition of the fuel when it meets higher temperatures.
Note that in both cases, your Check Engine light will be on. In any case, the above symptoms may not necessarily be due to a faulty EGR valve. But it does not hurt to be sure. If you notice such symptoms in your car, it is best to take it to the mechanic to be checked out and repaired if necessary.
