Raspberry Pi 3, ODROID-C2 and Pine A64+ Development Boards Comparison

Raspberry Pi 3 and hardkernel ODROID-C2 launched the same day, and together with Pine A64/A64+, are the only ultra low cost (<$40) 64-bit ARM development boards available or soon-to-be available, so I’ve decided to make a comparison of the three boards the same way I did with ~$10 boards with a Raspberry Pi Zero, C.H.I.P, and Orange Pi One comparison. I’ve used features of Pine A64+ instead of Pine A64 since features and price are closer to the other two boards. Text highlighted in green means a board is clearly better than the other two for a given features, while a red highlight means it’s the weakest of the three. Raspberry Pi 3 ODROID-C2 Pine A64 Plus Processor Broadcom BCM2837 quad core Cortex A53 processor @ 1.2 GHz(4x ~2760 DMIPS) Amlogic S905 quad core Cortex A53 processor @ 2.0 GHz(4x ~4600 DMIPS) Allwinner A64 quad core Cortex A53 processor @ […]

Makibes F69 IP68 Smartwatch & Fitness Tracker is Designed for Swimming

The market is flooded with wearables such as smartwatches and fitness trackers that all track activities (walking/running) with more or less accuracy, and while some offer good IP67 or IP68 ingress protection rating, or even better 5ATM rating, allowing them to be used in water, I have not found many that can actually track swimming patterns, especially among the cheaper ones. But that’s exactly what Makibes F69 sports smartwatch promises. Makibes F69 specifications: MCU/Memory/Storage – TBD Display – 1″ round capacity touchscreen display, 128×128 resolution, always on Connectivity – Bluetooth 4.0 LE Sensors – 3-axis accelerometer and gyroscope, heart rate monitor Battery – 180 mAh charged via magnetic dock good for 6 days in power saving mode, 4 days in “healthy” hear rate mode, and 30 hours using the HRM in sports mode. Dimensions – 38 x38 x 10 mm (stainless steel case, silicon band) Weight – 34 grams IP […]

F68 Smart Watch Review

After No.1 D3 and SMA-Q smartwatches, Makibes F68, or just F68, is my third attempt at reviewing a smartwatch, and on paper it matches all of my main requirements namely always-on display, fitness tracking with heart rate monitor, one week of battery life, and IP67 ingress protection rating to have some waterproofness. I’ve already taken pictures of the device, so today I’ll go through the user interface on the watch, and Android app, and report my experience after using the watch for over 10 days. The watch has an e-Paper display with decent viewing angles, and very good readability during the day, however at night, you’ll need to find the light switch or use a torchlight, as the watch does not have backlight at all, and it’s unreadable. There’s actually no buttons at all and everything is controlled via the touchscreen, and/or the app available for Android or iOS. The […]

Hexoskin Smart T-Shirt Keep Tracks of Your Activity with 42,000 Data Points per Minute (Crowdfunding)

There are now many smartwatches with electro-optic hear rate monitors, but based on my short experience so far, if you want something  accurate and reliable, you’d still better use a chest trap. Another potentially more comfortable option would be to use Hexoskin Smart T-shirt, and on top of the usual fitness data (step count, calorie burn, distance and heart rate), also measure your breathing rate and volume. The T-shirt also supports Bluetooth Smart to send back all the data to your smartphone or other devices such as bike computers or smart watches. The company already has Bluetooth Classic T-Shirt, but there latest versions will offer longer battery life and Bluetooth 4.2 LE connectivity. Hexoskin T-shirt 2016 specifications: Bluetooth Smart 4.1 connectivity via Cypress EZ-BLE PRoC module Heart rate, RR intervals, fatigue and stress indicator (Heart Rate Variability). Breathing rate and breathing volume. Activity intensity, peak acceleration, steps and cadence. Analog 256Hz […]
