Newyes SyncPen Bluetooth Pen Digitizes Your Handwriting to the Cloud (Crowdfunding)

Neweyes SyncPen

When I first found out about SERVO K07 bluetooth pen last month, I initially hoped it would allow users to digitize their handwriting or drawing and synchronize it to their phone or cloud, but it was not to be the case and instead it was just a 6-in-1 phone/pen/audio player/audio recording/camera/flashlight. But Newyes SyncPen does exactly that: it allows you to write on paper or a writing pad while digitizing your creation on the fly, and storing the result in the cloud. It works thanks to a tiny camera embedded in the pen capturing data at 200 fps. Newyes SyncPen hardware specifications: Connectivity – Bluetooth 4.2 Memory – 32MB, enough to store 800 pages of A5 paper content Pressure levels – 1024 Tiny camera @ 200+ fps Audio – Microphone Battery – 3.4V / 260 mAh Lithium Polymer battery good for about 8 hours; 1.5 hours charging time Dimensions – 16.35 x 1.33 ∅ cm Weight – 22 grams For …

Allwinner MR133 Processor Targets Robot Vacuum Cleaners

Allwinner MR133

It’s been a while since I’ve seen a new processor from Allwinner, so today I got curious and visited the company website hoping to find maybe some news about the first Cortex-A7x processor from the company. But instead I found something else intriguing with the new Allwinner MR133 processor specifically designed for “SLAM/VSLAM intelligent robot sweeper solutions”. In other words, Allwinner has just launched a processor for robot vacuum cleaners… Allwinner MR133 key features and specifications: CPU – Quad-core Arm Cortex-A7 processor @ 1.8GHz with 32KB L1 I-cache + 32KB L1 D-cache per core, 512KB L2 cache, low-power CoolFlex power management architecture GPU – Arm Mali 400MP2 with support for OpenGL ES 2.0/1.1, Direct3D 11.1, OpenVG 1.1 Memory I/F – 32-bit DDR4/DDR3/DDR3L/LPDDR3/LPDDR4 Storage I/F – eMMC 5.0 flasj, compatible with eMMC 5.1, support Full Disk Encryption(FDE) 8-bit TLC/MLC/SLC/EF NAND flash, supports FDE LDPC/80-bit BCH/1024bytes Video Engine – H264 HP encoder 1080p @ 60fps, JPEG encoder up to 4096 x 4096 …

ESP8266 based ANAVI Light Controller can be Programmed with Home Assistant or the Arduino IDE (Crowdfunding)

ANAVI Technology previously launched a Light pHAT allowing for RGB Light strip connection to Raspberry Pi boards, and during my review of ANAVI Light pHAT with Raspberry Pi 2, it did the job, but if that’s all you want to do, the  Raspberry Pi board is clearly oversized & overpowered for the job. So Leon ANAVI got back to the drawing board and designed a similar open source hardware board – called ANAVI Light Controller – with an built-in ESP8266 module that removes the need for a fully fledged Linux board. ANAVI Light Controller specifications: Wireless Module – ESP8266MOD module based on ESP8266 Tensilica L106 32-bit processor Connectivity – WiFi 802.11 b/g/n Expansion Terminal block for 12 V RGB LED strip 3x I2C headers for sensors Debugging – UART header Misc – Button Power Supply – 12 V via power barrel jack Dimensions – 75 mm x 40 mm Certification – Open Source Hardware Association (OSHWA) BG000005 The board can …

Sonoff S26 WiFi Smart Plug Works in All/Most Countries, Sells for under $10

Sonoff-s26-wifi-smart-plug-europe-usa

One recurring issue with smart plugs / sockets is that they are often designed with a specific prong type, so if you want to use them in our country you may have to add an adapter, which may not be ideal, since the socket may fall off or have bad contact. Sonoff S26 WiFi smart plug solves that issue as ITEAD Studio made it available in six different versions for China, Australia, United Kingdom,  Europe type F, Europe type E, and the United States. Sonoff S26 specifications: Standard – US/ UK/ CN/AU/ EU(type F/E) Power supply – 90V~250V AC @ 50/60Hz Max.

FOSSASIA Summit 2018 Schedule – March 22-25

FOSDEM is the “Free & Open Source Software Developers’ European  Meeting” takes place the first week-end of February every year in Brussels, Belgium.  It turns out there’s an event in Asia called FOSSASIA Summit that’s about to take place in Singapore on March 22-25. There are some differences however, as while FOSDEM is entirely free to attend, FOSSASIA requires to pay an entry fee to attend talks, although there are free tickets to access the exhibition hall and career fair. There are also less sessions as in FOSDEM, but still twelve different tracks with: Artificial Intelligence Blockchain Cloud, Container, DevOps Cybersecurity Database Kernel & Platform Open Data, Internet Society, Community Open Design, IoT, Hardware, Imaging Open Event Solutions Open Source in Business Science Tech Web and Mobile Since the event is spread out over four days, it should be easier to attend the specific sessions you are interested in. I’ve created my own virtual schedule,  but since talks about IoT …

Synthetic Sensors Combine Multiple Sensors and Machine Learning for General-Purpose Sensing

Sensors can be used to get specific data for example temperature & humidity or light intensity, or you can combine an array of sensors and leverage sensor fusion to combines data from the sensors to improve accuracy of measurement or detect more complex situation. Gierad Laput, Ph.D. student at Carnegie Mellon University, went a little further with what he (and the others he worked with) call Synthetic Sensors. Their USB powered hardware board includes several sensors, whose data can then be used after training through machine learning algorithms to detect specific events in a room, car, workshop, etc… List of sensors in the above board (at frequency at which data is gathered): PANASONIC GridEye AMG8833 IR thermal camera  (10 Hz) TCS34725 color to digital converter (10 Hz) MAG3110F magnetometer (10 Hz) BME280 temperature & humidity sensor, barometer (10 Hz) MPU6500 accelerometer (4 kHz) RSSI data out of 2.4 GHz WiFi module (10 Hz) AMN21111 PIR Motion sensor (10 Hz) ADMP401 …
