Wi-Fi SD Card Adapter for micro SD Cards Sells for $15 and Up

Wi-Fi SD cards are mostly used with camera in order to wirelessly transfer photos or/and videos to your computer or mobile device without having to take out the card or transfer them via a micro USB cable. I first discovered this type of card with Toshiba FlashAir in 2011, but now EyeFi seems to be the most popular brand, and comes in different sizes with the 8GB Wi-FI SD card selling for $44 on Amazon US. There are cheaper alternatives with some Wi-Fi SD card adapters accepting micro SD card selling for about $15 and up on Aliexpress or Buyincoins, and DX calls it CY EP-027, but sells it for $23. It does not come with storage but since a 8GB class 10 SD card now costs about $8, it’s still nearly 50% cheaper compared to the 8GB EyeFi SD card. Some features of the card: Max micro SD card […]

$35 Bluetooth Blood Pressure Monitor Works with Android and iOS

People with hypertension or other heart conditions may want to monitor their blood pressure daily, and since I was asked recently, I studied blood pressure monitors available on the market from Chinese websites. The simplest ones that simply display the results on an LCD are quite inexpensive since they cost about $15 shipped, unless you buy brands like Omron. You’d then need to enter the data in a spreadsheet or on paper after each measurements, so you’d rather have the process more streamlined, you could consider a Bluetooth version that will automatically keep measurements stored in your Android or iOS smartphone, such as the model below that sells for around $35 on Aliexpress and Ebay. Key features for this unnamed digital blood pressure monitor Display – 70 x 55mm; 3x 3 Digits lines for systolic and diastolic pressures, and heart rate; Memory/Heartbeat/Low battery indication Measurements: Oscillometric method Pressure Range- 0 […]

GroBotz makes me think of Lego applied to robotics. The project consists of modules such as motors, sensors, buttons, switches, or cameras that snap together in order to create a robot on wheels, games, toys, a musical instrument, or whatever idea you may have, and the hardware is then programmed using a graphical user interface. A Raspberry Pi board is used for the brain of the robot, and Microchip PIC MCUs for the smart blocks.

Vidonn X6 Activity Tracker Promises Up to 15 days Battery Life

I reviewed Vidonn X5 fitness tracker last yet, and I found many issues or letdowns: battery life is too short (2 days), the digits are much smaller than advertized, the screen cannot be read under direct sunlight, a button must be pressed to check the time, the smartband is not as waterproof as advertized, and the Android app is a disaster.
