PowerStream Lithium Polymer Batteries are Bendable and Ultra Thin (0.5 to 2 mm)

Electronics components and boards are getting smaller and smaller, and for battery powered devices, the battery may take a big chunk of the volume, and in some cases like smart cards, typical battery are not suitable. PowerStream has designed ultra thin bendable LiPo batteries that aredesigned for smart cards and RFID tags that needs their own power, but I could envision that if battery capacity increases, and/or energy harvesting becomes a more common feature, they could be used for wearables, for example by placing them inside the wristband. The main features for the battery as listed by the company: Operating voltage – 3.6V High energy density No memory effect Self-discharge is less than 3% per month Charge/discharge cycle characteristics are excellent Safety characteristics are excellent Processing temperatures for these cells is 100°C for less than 60 seconds, 120°C for less than 20 seconds and 140°C for less than 5 seconds.

Designing a 3D Printed Jig to Flash Firmware to ESP8266 based Light Bulbs

Karl here. I have to say that my favorite part of 3D printing is designing things from scratch. Recently a reader was asking about a way to flash a lot of Ai Lights on a project he was working on. I suggested 3D printing a jig that pressure fits pins. He didn’t have a printer, and we exchanged contact information and he sent me one of the lights and some pogo pins from Amazon. Design in Fusion 360 I started by taking a picture of the light to get my pin placement. I set a scale by measuring a known distance then printed and tested. It took about 3 iterations to get them to line up in real life. Keep in mind camera lenses distort reality and knew It would take a couple times. I would just let a few layers print then stop and line everything up. I had […]

Review of Vobot Alarm Clock with Alexa

Karl here with a review of Vobot sent By Cafago. I had to Google it when I was asked to review it. Turned out it was an Echo type device with a pixel display and a battery. It started as an Indiegogo campaign. I had been wanting to try to do some sort of voice control with my home automation so I agreed to review it. Vobot Clock C1 Specifications These are pulled from Vobot’s website. No power supply is included but a long USB cable is. Vobot Setup I let my wife do the initial setup as I figured that she would use it the most. She followed the instructions, and it seemed straightforward from what she told me. She said she had to reboot it once during a step but it continued the setup with no problems. She tied to our Amazon Prime account, and she quickly was […]

Review of Koogeek BP2 Bluetooth Blood Pressure Monitor

Koogeek BP2 is an FDA approved smart blood pressure monitor that connects over Bluetooth to your Android or iOS smartphone, or WiFi to the cloud. The company sent me a sample for evaluation, so let’s get started right away. Koogeek BP2 Unboxing The device is sent in a cardboard package with Koogeek brand… and some more derails about the specifications on the bottom of the package. I asked the company to confirm about FDA approval, and they told me to look for K134029 on the FDA website, which lead me to this document testing Shenzhen Belter Health Management and Analysis ePA-46B, and comparing it to the results of Omron HEM-7200-Z (BP742) with the conclusion being that: The Belter Blood pressure meter (ePA-46B) is substantially equivalent to the predicate devices. Koogeek BP2 is the same as Belter ePA-46B, but just rebranded, and with a different mobile app. In the package will find […]

Intel unveiled the Compute Card at the very beginning of the this year, without that many details, except it would included a 7th Gen Intel Core, memory, storage and wireless connectivity, and connect compliant dock with a new standard connector featuring USB-C and extra I/Os. Later this year, we learned more details about some Apollo Lake and Kaby Lake Compute Cards including specifications and block diagram. However those cards won’t be of any use without docks, and while NexDock promised a laptop dock for the cards, I have not seen any other announcements, but we now have some info about Intel’s own Compute Card dock that looks like a mini PC as the company released technical specifications and user manuals for DK132EPJ dock, and three Compute Card SKUs.   Intel Compute Card Dock DK132EPJ specifications: CPU, Memory, Storage, Wireless – Via slot supporting certified Intel Compute Cards Video Output – HDMI and […]

WizziKit is a DASH7, LoRa and Sigfox Wireless Sensor & Actuator Network Kit

Over the last few years, I’ve written several article about LoRaWAN, Cellular IoT, and Sigfox based long range low power IoT solutions. DASH7 is another LPWAN (Low Power Wide Area Network) standard that operates on the same 868 and 915 MHz ISM bands as LoRa and Sigfox, but has much lower power consumption, and the cost of a shorter range up to 500 meters, instead of the 5+km associated with LoRa or SigFox. The DASH7 Alliance Protocol (D7A) is an Open Standard, and if you want more details you can download version 1.1 of the specifications on DASH7 Alliance website. I’m writing about DASH7 today thanks to an article on ST blog about Wizzilab’s Wizzikit, an evaluation kit and framework for DASH7 with a gateway, and several nodes that can also optionally support LoRaWAN and Sigfox protocols. The kit is comprised of the following items: WizziGate GW2120 Ethernet/Wifi/Dash7 gateway – based […]
