Rocketbook Takes Your Written Notes to the Cloud, Erases in Your Microwave Oven (Crowdfunding)

Maybe I’m old style, but I still prefer taking notes with pen and paper rather than typing on a computer. That means I need to buy some notebooks (the ones made of paper) from time to time, and once they are full I store them away. But now you can combine the good old written notes with the cloud thanks to RocketBook, a standard looking notebook combined with a mobile app that will scan your notes and send them to various cloud services, and more amazingly it’s re-usable since you can erase by putting in 30 seconds your microwave. I was perplexed at first, as it looked like a scam to me. But finally, I’m pretty sure it’s not since it’s using existing technology, namely Pilot Frixion pens. They looks like standard ball-point pens, but they use a “thermo-sensitive gel ink formula” that can be erased with friction, and they […]

Sigrok and Pulseview in Ubuntu 14.04 with UNI-T UT61E Digital Multimeter

A couple of months ago, I received a new digital multimeter UNI-T UT61E that can send data to a computer via a serial cable, and allows you draw some nice charts. I’ve already done that in Windows 7 with the provided tools, and reported on the power consumption of some Chinese Android TV boxes. However, since I use Ubuntu 14.04 as my main operating system, Linux based tools would be more convenient, and open source sigrok-cli command line client and its graphical interface pulseview are supposed to support UT61E DMM, so I had to give it a try. A Quick Look at UNI-T UT61 Digital Multimeter Before going into Sigrok, I’ll quickly show what the multimeter received from DealExtreme . It took longer than expected to ship because of of  included 9V battery, and at the first shipping attempt it was returned to DX, but after 8 weeks or so, […]

How to Build a Single Kernel Module (Driver) in Ubuntu

When I bought UNI-T UT61E digital multimeter,  I planned to to use the open source tool Sigrok to capture voltage, current or resistance data with my Ubuntu 14.04 machine. Unfortunately, it was just not working for me and I kept getting some “Invalid function byte” error messages, so I asked on Sigrok mailing list, and since it worked for others, I was in big troubles. It turned out the RS-232 to USB dongle I used:

was most likely to culprit, so I decided to buy another random USB to serial dongle on eBay, and after a few weeks I received it only to find out it had the exact same VID:PID, so I was out of luck. Finally, I gave up on Sigrok on Linux, and tested the power consumption of some Rockchip RK3288 & Amlogic S802 devices in a Windows 7 virtual machine running in my Ubuntu 14.04 […]

DonglePi is a USB Dongle with a Raspberry Pi Header for your PC

While the newer Raspberry Pi A+, B+ and B2 boards feature the new 40-pin connector, the Raspberry Pi boards Model A and B have a 26-pin expansion header, but both are use to access GPIOs, UART, SPI, I2C and interface with external hardware, and many add-ons boards have been developed for the Raspberry Pi. But what if you’d like to use R-Pi add-ons board on your PC, or instead you are developing your own add-on board, but would like to do so directly on your PC for convenience? DonglePi is the answer. It’s a small USB dongle with Atmel SAMD21 MCU and a 26-pin Raspberry Pi compatible header, that you could use connect to your Android/Linux/Windows PC to play with GPIO, I2C, SPI, Serial, PWM just like on a Raspberry Pi, and using RPi/GPIO or smbus Python libraries for programming. The project is still in development, and so far most […]

iConsole Micro Intel Atom TV Stick To Run Android 5.0 based Console OS

Console Inc., previously Mobile Media Ventures, Inc.,  is the company developing Console OS operating system based on Android 4.4 / 5.0 for Intel platforms that includes customizations for a better desktop experience, and you can already try the preview version of Console OS Standard for free on some Intel hardware, with another paid version to become available at the time of the stable release. The company has now announced iConsole Micro a Console OS HDMI TV Stick based on a quad core Intel Atom processor that looks very much like MeegoPad T01, but it’s said to be based on Intel Compute Stick technology. iConsole Micro specifications have not been fully released, but here’s what we know so far: SoC – Unnamed Intel Atom 64-bit quad core processor System Memory – 2 GB RAM Storage – 32 GB eMMC + micro SD slot up to 128GB (160GB in total) Video & […]

ARM Cortex M0+ Based Arduino Zero Pro Board Gets Listed on Arduino.org

A new “Arduino Zero Pro” board has been listed on Arduino.org, which looks very similar to the Arduino Zero board announced last year, with Atmel ATSAMD21G18 ARM Cortex M0+ MCU, and that is still listed as “Coming Soon” on Arduino.cc website. So it feels a little odd Arduino would release a board with basically the same features. Arduino Zero Pro key specifications are indeed exactly the same: Microcontroller – Atmel ATSAMD21G18 32-bit ARM Cortex M0+ MCU @ 48 MHz with 32 KB SRAM, 256 KB flash, up to 16KB EEPROM (By emulation). 48-pin LQFP package. Digital I/O Pins – 14, with 12 PWM and UART Analog Input Pins – 6, including 5 12bits ADC channels and one 10 bits DAC DC Current per I/O Pin – 7 mA USB – 2x micro USB ports Debugging – USB via Atmel’s Embedded Debugger (EDBG) on-board debugger, and JTAG Misc – reset button, […]

Xilinx Introduces Zynq UltraScale+ MPSoC with Cortex A53 & R5 Cores, Ultrascale FPGA

Xilinx Zynq-7000 dual core Cortex A9 + FPGA SoC family was announced in 2012, and provides a wide range of SoC with features and price range, and led to low cost ARM + FPGA such as ZedBoard, and more recently Parallela and MYiR Z-Turn boards. The company unveiled its successor with Zynq UltraScale+ MPSoC providing five times more performance per watt, with four ARM Cortex A53 cores, two ARM Cortex R5 real-time MCU cores, a Mali-400MP GPU, an UltraScale FPGA fabric manufactured with 16nm FinFET+ process. There are two main sub-families in Zynq Ultrascale+ MPSoC for “smarter control & vision”, and “smarter network”. Both share the same processing systems (CPU, GPU, MCU, Peripherals, Security), but the networking family has beefier FPGAs,  and lacks the H.264/H.265 video processing unit found in the control & vision version: Processing Systems Processor – Quad ARM Cortex A53 MPCore up to 1.3GHz Real-time Processor – […]
