Geekbes BR30 WiFi RGB Light Bulb Delivers 900 Lumens

We’ve previously covered two smart RGB light bulbs with AI Light and Sonoff B1 models, and they are especially interesting since they can work with open source firmware like ESPurna or Sonoff-Tasmota. However, their brightness is limited, and in the case of Sonoff B1 it’s especially true when using colors other than white. A brighter WiFi RGB LED light bulb might be Geekbes BR30 which is said to be rated 9W and delivers 900 lumens against the 6W / 600 lumens for Sonoff B1, and does not cost more much at $19.99 on GeekBuying. Geekbes BR30 specifications: Color – White: 2700K-6500K + RGB (16 million colors) Brightness – 900 lm Light emitting angle – 120 degrees E26 plug Connectivity – WiFi Supply Voltage – AC100-240v 50-60HZ Rated Power – 9W Standby Power – <= 0.3 W Service life –  20000 hours Temperature Range – -20 to +40°C Ingress Protection Rating – IP20 Dimensions –  Ø95 x 116mm Weight – 142g …

Tail it is a Family of WiFi & Cellular GPS Trackers for Things, Pets, and Bicycles (Crowdfunding)

Tail It Cellular GPS Tracker

We’ve previously written about Ping, a tiny Cellular GPS tracker that promised to last 3 months on  a charge. The raising money part of the crowdfunding campaign itself was successfully with over one million dollars raised, but as with many such campaigns there have been delays, and some people still have to receive theirs, not to mention people complaining about poor battery life and other issues. But there seems to be another option now with Tail It Technologies now offering four different “Tail it” cellular GPS trackers (with WiFi too) for things, pets, and even one designed specifically for bicycles. The company has already sold their devices to thousands of customers in Norway, so they should be working, and on-time delivery should hopefully not be an issue. All four GPS trackers come with 2G, 3G, 4G, and WiFi connectivity,  a 5-meter accuracy, and share the same electronics and firmware. Here’s a list of the four models and their main features: …

Firewalla is a Tiny Firewall Appliance Based on NanoPi NEO Board

Firewalla NanoPi NEO Firewall

FriendlyELEC Nanopi NEO and NEO2 boards are really cool and inexpensive little Arm Linux boards suitable for all sort of headless application. I’ve reviewed one with their NAS Kit, and run one around the clock as a Domoticz/MQTT server. So it should come as no surprise that some people want to leverage the hardware in their own products, and Firewalla most likely relies on a NanoPi NEO board for their cute firewall/parental control/VPN appliance.Firewalla specifications: SoC – Unnamed quad-core Arm processor @ 1.0 GHz System Memory – 512 Megabyte DDR RAM Storage – 16GB MicroSD Storage Connectivity – 100 Mbit Software Packet Processing Power – 5V via micro USB port Dimensions – 2.8 cm thick The device ships with a flat Ethernet cable, a USB power cable and US type power adapter, and a one year limited manufacturer warranty. The company does not actually mentioned NanoPi NEO board anywhere, but the specifications and connector layout make it clear it should be based …

ASUS VivoWatch BP is a Fitness Tracker that Measures Blood Pressure

If you need to monitor your blood pressure regularly, you may have used one of those blood pressure monitors that you wraps around your upper arm, and display results on an LCD display, and in some cases, synchronize the data with your smartphone Bluetooth. Those devices do the job, but they may be inconvenient to use daily, and some people just forgo measurements. Omron first introduced a more user-friendly solution with their Project Zero BP6000 blood pressure monitor-in-a-watch in 2016, further refined with Project Zero 2.0 watch in 2017. That’s all good, except for the same details that neither versions of the watch – to be called Heartvue – are for sale, as the company is still working on FDA approval… ASUS has filled the void with VivoWatch BP watch, and IMHO has taken a more clever approach to launching their product, since the watch will be available in Asia this summer, and in the US after FDA approval, which …

Droplet Computing Aims to Run Apps on any Device (Regardless of the Operating System)

Droplet-Computing

The most popular apps are normally ported to all commonly used operating systems such Windows, Mac OS, Linux, Android and iOS, but apps will a lower user base or older apps may not to ported to all operating systems due to the development time / costs involved. In order to solve this issue, UK based Droplet Computing has introduced Droplet Universal, a patent-pending application container solution that decouples applications from the operating system, and enables applications to run on any device, on- or offline. The solution relies on WebAssembly, and allows you to run the app – placed in a low footprint universal container – from a web browser with Chrome v60 (v62 for Android), Firefox v52, Safari v11, and Edge v16 or greater currently supported. Arm and x86 platform are supported, although it’s not yet possible to run Arm apps on x86 with Droplet Universal. It’s hard to know how well this works without testing it, but we may …
