The Latest Water Quality Tester Pen of Xiaomi

The manufacturer of Chinese origin Xiaomi began manufacturing and selling high-end smartphones at a very low price, however, a time now has also produced other devices such as wearables, networking products such as routers or repeaters Wi-Fi, wireless speakers , televisions and has now launched a water quality meter.

The Xiaomi TDS Tester Pen is a small device that allows us to measure the quality of water quickly and easily. We can measure this quality water directly from tap water, boiled water, bottled water and even also of our tanks. The device can detect the three best known impurities water: soluble salts, including ionic organic compounds and heavy metals.

This device has two small factory built batteries to function and is well protected against water IP68 certified, which is obvious because we have to introduce the meter in the water and can not be damaged, as well as being waterproof, also has anti protection rust and corrosion. Incorporated batteries are long lasting because it enters standby mode quickly and consumption is minimal. 

This small device to measure water quality will be the ideal companion Xiaomi water purifier, known Xiaomi My Water Purifier. 

If you are interested upon this kinds of electrical measuring tools, you could purchase it from Banggood and it is now sold less than $14.99. Although it is small and cheap, it shows you the useful functions. Just have a try and you will not be regret! 

Arduino SCM DIY Kit And Component For Enthusiasts

As for the Arduino enthusiasts, they would be very please to find something useful and practical components to do the DIY. Yesterday, I happen to find two kinds of this type components, one is the module board, while the other is the solderless wire cable kit. Both of them are sold in low prices. Then, I will share you something detailed about them. I hope this text is benefit for you. 

Firstly, I wanna share you about the arduino mini pro module board. It takes a very small size but it is one kind of high quality component and soldering material. Besides, it is the new version one and features 5V 16MHz specifications, arduino compatible part. It can be do the updating and you just need to follow three steps as follows: 

First, prepare an Arduino Uno, Mega or similar to act as ISP as described at http://arduino.cc/en/Tutorial/ArduinoISP. Second, write it up as shown in flasbootloader_connected.png (Picture Reveiw of SKU099688). Third, use Arduino IDE to flash the bootloader of the corresponding Pro/Pro Mini (5V, 16MHz) to SKU099688 or SKU06. The detailed introduction you can see at Banggood website. This one only sold $2.73.

The second product I wanna share you is about the solderless breadboard jumper wire kit. This one made by high quality materials to provide you high quality and durable use. It is a good choice for construction or repair. Equipped with solid copper leads, it features wonderful stability and high frequency response. 

Actually, this breadboard is an invaluable tool, only allowing the electronic components to be interconnected in an almost endless number of ways to produce working circuits. However, this breadboard pattern is an useful combination, which  serves to distribute power and provide common ground points. If you need it, you can purchase it at Banggood, low price just costing you $2.9.
