In recent years, wearables such as fitness tracker have become popular to monitor the number of steps walked, calories burnt, and distance covered during your daily activities. These products are not always accurate however, and it get better data instead of having your wear a monitoring device, companies such as BodyCap are working on ingestibles, pills that some electronics, that the user swallows, and tranmit accurate data at a short range. One of the first product from the company is e-Celsius Performance that aims to measure body temperature of athletes, in order to optimize their performance. The pill has the following technical specifications: Data Storage – Up to one year, and up to 2000 samples Sampling – 30 seconds Accuracy – 0.2°C Connectivity – Wireless transmission (433 MHz); up to 1 meter range Battery – Not sure, but it can last 20 days Weight: 1.7g Dimensions – 17.7mm x 8.9 […]
Thunderboard Wear is a $75 Smartwatch Development Board by Silicon Labs
A few days ago I watched an ARMDevices.net’s video about an ARM’s smartwatch reference design running mbed OS 3.0, powered by a Silicon Labs EFM32 Giant Gecko Cortex M3 MCU, and promising up to 2 months battery life on a 160 mAh battery. While I could not find the full details about the reference design, I noticed Silicon Labs also launched a development board called Thunderboard Wear, based on the same platform, just quite bigger, and still wearable… (Sort of) Thunderboard Wear specifications: MCU – Silicon Labs EFM32GG995F1024 ARM Cortex-M3 MCU up to 48 MHz with 128 kB RAM,1 MB Flash External Memory – 256 kB external SRAM External Storage – micro SD card slot Display – 128×128 pixel Memory LCD from Sharp Connectivity – Bluetooth 4.1 smart module (Silicon Labs BGM111), upgradeable to Bluetooth 4.2 Sensors Ambient Light Sensing (ALS) and Proximity/Gesture via Silicon Labs Si1141. Optical hear-rate monitoring […]
ShiftWear Shoes Integrate a Flexible e-Paper Display, Energy Harvesting Capabilities (Crowdfunding)
ARM CTO, Mike Muller, showcase imprinted electronics, that is an integrated circuit printed on a plastic film, at ARM TechCon 2015, and several products are featured flexible displays, so in future flexible electronics could bring innovation applications from truly wearables electronics to traceable bank notes, and so on. A company has launched an Indiegogo campaign for a new product, that’s both cool and relatively useless, with ShiftWear sneakers that integrate a flexbile e-Paper display, a battery that recharges by harvesting energy from your steps, and some connectivity (likely Bluetooth LE) to update the display from your iOS, Android or Windows device. Three models are available: L1, M1 and H1 referring to low height, medium height and high height of the part around the ankle (heel tab?). But all three have basically the same features: Always-on HD color e-paper flexible display Up to 30 days of battery life Waterproof up to […]
No.1 D3 Smartwatch (Mediatek MT6261) Review
Since I’ve listed the specs and torn down No.1 D3 smartwatch, I’ve spent several days wearing the smartwatch / watchphone, and trying most of its features, so it’s time for a review. I’ll go through all screens of the user interface, include a video review, before providing a conclusion to this review Charging the watch take between 15 to 30 minutes, and you can turn it on by pressing the only button on the side of the watch for a few seconds. The first menu you are likely to see if the one with the phone functions including the Dialer, messaging, phonebook and call logs. You can use these in two ways: with a micro SIM card inserted into the watch, or/and via your smartphone connected over Bluetooth. I mostly used the watch connected to my smartphone, but both methods worked for me. When you receive a call, it’s not […]
NO.1 D3 Smartwatch Specs, Unboxing and Teardown
There are now many wearables, including fitness bands and smartwatches, on the market, but to me many fail on battery life, visibility, and price. The one that would match my requirements the best would be SMA-Q smartwatch, but in the meantime, I’m also interested in testing some more wearables at different price points. Tinydeal sent me NO.1 D3 smartwatch that sells for just $22.99 shipped. I’ll go first through the specifications, before checking of the watch more closely, and in a few days writing a review of the device. NO.1 D3 Smartwatch Specifications You should not expect much for this price, but the watch is surprisingly feature-packed (as taken from tinydeal website): SoC – Mediatek MT6261 processor with 32Mbit RAM, 32Mbit Flash Storage – Internal micro SD slot up to 16GB Display – 1.22″ capacitive touchscreen IPS display with 128×128 resolution Connectivity – Bluetooth 3.0 Cellular – 1x micro SIM […]
Ambiq Micro Apollo Low Power MCUs Promise Cortex M4F Performance at Cortex M0+ Energy Efficiency
Ambiq Micro is a US company founded in 2010 that focuses on “extremely low power” semiconductors leveraging their patented Subthreshold Power Optimized Technology (SPOT) platform. Earlier this year, they announced their first low power Cortex-M4F MCU Apollo family with claims of 5 to 10 times lower power consumption compared to other micro-controllers with the same performance. According to an EETimes article, they’ve at least partially backed their claims with a live demonstration at ARM TechCon 2015. Before checking out the test results, let’s have a look at the main features of Apollo MCU family: 32-bit ARM Cortex-M4F processor @ up to 24 MHz, with FPU, and wake-up interrupt controller with 12 interrupts Up to 512KB flash, 64-KB low-leakage RAM “Rich set of timing peripherals” Peripherals I2C/SPI master; I2C/SPI; UART; 10-bit, 13-channel, 1MS/s ADC Temperature sensor with ±2°C accuracy Voltage Range – 1.8 to 3.8V Power Consumption: active mode: 30µA/MHz (executing […]
SMA-Q Bluetooth Smartwatch Features a Color E-Paper Display, an Heart Rate Monitor… for $56 and Up
My Vidonn X5 activity tracker died on me a few weeks ago about over a year of service. While it was useful to keep me active thanks to its “steps” counter, I realized I was not a big fan of OLED displays as they aren’t turned on all the time in order to save power, and are hard to read when there’s a strong sunlight, the battery did not last that long (about 2 days), and using motion sensors to evaluate activity is not that accurate. So I’m interested in wearables with always-on displays, readable in sunlight, that don’t suck too much battery (e.g one charge per week), and with a strapless heart rate monitor. The first three are normally only achievable with E-Ink or E-Paper displays and the latter have become much more common thanks to electro-optical heart rate monitors. I’m also a budget conscious guy, so I’d like […]
Bluboo Xwatch is an Android Wear Smartwatch Powered by Mediatek MT2601 SoC
So far, we’ve only seen Android Wear devices by large companies such as Motorola, LG, or Huawei, simply because you have to sign an agreement with Google in order to be allowed to load Android Wear on your device. Last year, a startup launched their own “Android Wear” watch on Indiegogo, but when Google found out the campaign got pull out since it was not going to happen. But the situation may have changed since then, as I’ve been contacted by Bluboo, which should be brand from Shenzhen Huihua Exploit Technology Co., Ltd, about their upcoming Bluboo Xwatch sports smartwatch running Android Wear, and the company confirmed they were “working with a third-party company to help them get this agreement”. I’m guessing/hoping the third party company might be Mediatek themselves. Bluboo Xwatch preliminary specifications: SoC – Mediatek MT2601 dual core ARM Cortex A7 @ 1.2GHz with ARM Mali-400 MP GPU […]
