Assembling a large battery of 18650 lithium ion battery. How it make in Chinese factory

Assembling a large battery of 18650 lithium-ion battery makes one operator. First, the worker connects the batteries in one block. Then, contacts are soldered to connect the batteries in one circuit. Further, the controller chip is connected to the battery pack.


Arduino – BLUETOOTH & ANDROID PIR ALARM with call and sms Functions!

Hello world! Today i made a android app that communicates with a arduino using the HC-06 Bluetooth module for a PIR Motion sensor GSM Alarm. You can set 1 phonenumber to the DATABASE that needs to be called when movement is detected. When movement is detected it will call you and you can listen what is happening in your home, If you missed the call you can send a SMS with the command “Call me” (it is case sensitive, so use capital C). You can also send a SMS command with “Disconnect” and the bluetooth module will disconnect. For the Schematic, Arduino Code, Android APP & Parts list follow the next link:

NOTE: You need to take a few steps for the APP to operate properly and you need to connect the Phone to a Charger.

Follow these next steps on your Android phone.
1: Settings, go to call, extra settings, turn off proximity sensor.
(Turns off screen during calls when on, and we want the screen to be on)

2: Settings, Location & security, setup screen lock to none.

3: Settings, Applications, development, turn on standby or might be named stay awake on your phone
(keeps screen on during Charging)

7 Raspberry Pi Alternative options Aside From Asus Tinker Board: Quicker, More cost-effective, Fantastic

Raspberry Pi, the payment card-sized computer and the pride of the English folks, has a robust rival originating from yet another sea-coast – the pride of the Taiwanese folks, Tinker Board. Whilst it has equivalent enhancements alongside Raspberry Pi, it’s going to be presented with even better technical specs but at a much more affordable price than Pi. On the other hand, the Tinker Board is not the only challenger for the best-loved mini computer amongst hobbyists; turns out, you’ll discover at least seven more.

More inexpensive Or Quicker Alternatives To Raspberry Pi

Raspberry Pi is the typical go-to single board computer for entertaining programming and practical projects. Nevertheless , just before purchasing one, it can be high-time to think about its rivals, which are speedier, greater, or maybe even better value, ZD Net reported.

VoCore 2. It is the new version of Linux and is open-source. It in addition costs only $15 and is beneficial to projects like building tailor-made wireless router or IoT.

VoCore2: $4 Coin-sized Linux Computer or A Tiny Router on Sterroids

C.H.I.P. it is additionally quite cost-effective at $9 an item. This is the verification of how low-priced computer is becoming. It consists of 1.0GHz CPU, 512MB RAM, 4GB Storage area, and has built in Bluetooth and Wireless internet.

$9 CHIP Computer Review:

Banana Pi M3. It has 2GB of RAM and offers Octa-core processor chip. It can uses a range of other OS just like Ubuntu, Android, Raspbian, plus more !.

Banana Pi M3 Review:

Parallella. It’s another mastercard-sized computer but is based on Adapteva’s Epiphany multiple-core chips. It could be used 3-ways: a standalone computer, a component in a parallel server cluster, or being a embedded device.

Parallella For Newcomers:

PixelPro. This has the Freescale i.MX6Q Soc Quad Core ARM Cortex-A9 that runs as high as 1GHz. It’s highly ideal for running multimedia applications of very rich quality on account of the 2GB 64-bit DDR3 RAM baked into it. It’s sold at $129.95 a piece but you will obtain a lot of power for what you’re covering.

4 Micro Single-Board Computers:

Udoo Quad. This $135 PCBA board can run both Android and Linux. Further, it features precisely the same quad-core as Pixel Pro but it’s really more and costs more too. Yet, it will be worth each and every cent on account of the power it has on the inside.

Arduino INDUSTRIAL 101. This is a $40 PCBA board which can be used either for industrial or commercial. It works with Atheros AR9331 CPU and has 64MB of RAM.

The Performance Of The Tinker Board

The Tinker Board has specifications that put it head to head against the reigning Raspberry Pi, The Verge reported. It provides a quad-core 1.8GHz ARM Cortex-A17 CPU and 2GB LPDDR3 RAM. Further, it includes 4 USB 2.0 ports and it offers support for gigabit LAN and also Bluetooth 4.0.

Also, the Tinker Board includes 3.5millimeter audio jack, microSD slot, and also a Micro USB for power. It can also be swapped with the 802.11 b/g/n Wi-Fi antennas and it offers an HDMI 2.0 port allowing for for 4K video.

Nevertheless , inspite of the 4K support, the Tinker Board is not able to support 4K Netflix streaming, therefore it is not great for the ones who’re planning to build up their own unique media center. In spite of this, it gives end users an improved 3D performance and has the ability to successfully work with H.264 or H.265 encoded file types.
