OpenDime is a Bitcoin USB Stick based on Microchip SAMD21 MCU, and ATECC508A Security Chip

The first time I heard about crypto currencies, specifically Bitcoin, was probably around 2011, and later in May 2012, I noticed a “micro-payments with Bitcoin digital currency” talk at a Barcamp. I did not think much of it at the time, but with hindsights, I should definitely have started to mine some Bitcoins considering the price was $5. Nevertheless, cryptocurrencies appear to be here to stay, and while most transactions occurs over the Internet, Opendime project has made a hardware USB dongle to store Bitcoins, and earlier this year, announced version 2 of their “Verified Bitcoin Credit Stick”. Hardware specifications of OpenDime v2.0 / v2.1 USB stick: MCU – Microchip / Atmel SAMD21 Cortex M0 MCU Security Chip – Microchip / Atmel ATECC508A Crypto chip with support for SHA-256, TRNG, and public key signing (ECDSA) USB 2.0 interface to connect to a computer Bitcoin seal The USB stick works like […]

Android Can Now Boot with a Full Open Source Graphics Stack on NXP i.MX6 Boards

While the Android operating systems is itself open source, it still relies on proprietary binary files to leverage GPU acceleration, VPU hardware decoding, wireless connectivity, and so on. It’s been possible to run Android with an open source software graphics stack, but it’s normally terribly slow and barely usable. But Collabora has announced it could now boot Android with a full-graphics stack on iMX6 platforms using no proprietary blobs at all. To do so, they leveraged the work done on Etnaviv open source drivers for Vivante GPUs, and adding the different formats used for graphical buffers in Android and Mesa library using modifiers representing different properties of buffers. They further explain: Support was added in two places; Mesa and gbm_gralloc. Mesa has had support added to many of the buffer allocation functions and to GBM (which is the API provided by Mesa, that gbm_gralloc uses). gbm_gralloc in turn had support […]

HiMedia Q30 (Hisilicon Hi3798MV200) Android TV Box Review – Part 1: Unboxing and Teardown

I’ve often read praises about HiMedia TV boxes in the comments section of this blog, but so far, I had never tested any of their products. This is about to change, since the company has sent me their latest HiMedia Q30 TV box running Android 7.0 on Hisilicon Hi3798MV200 processor, a cost-down version of Hi3798CV200 processor with the same CPU,a lower-end Mali-T450 GPU, about the same media capabilities, and less I/Os. I’ll start the review by checking out the TV box and accessories, as well as the PCBA, before reporting the experience with Android 7.0 firmware in several weeks. HiMedia Q30 TV Box Unboxing I received the device is a package that read “HIMEDIA Q30” and “Android TV Box”, and shows some of the key features like 4K @ 60 fps, 10-bit HEVC, HDR and Kodi support. The devices ships with an IR remote control with IR learning function for […]

Review of Wio Tracker with GPS, Bluetooth 3.0 and GSM Connectivity

Wio GPS – also called Wio Tracker – is an Arduino compatible board based on Microchip Atmel SAMD21 MCU with GPS, Bluetooth, GSM/GPRS connectivity, as well as several Grove connectors to connect sensors and modules for your IoT project. SeeedStudio sent me a sample for evaluation, so I’ve tested it, and reported my experience below by testing some of the Arduino sketches. Wio Tracker Unboxing All I got in the package was Wio GPS tracker v1.1 board. The top includes the Atmel MCU, an RGB LED, a microphone and 3.5mm AUX jack to make phone calls, a user and power button, a micro USB port for power and programming, a small 2-pin connector for a battery, and 6 Grove connectors for digital, serial, I2C and analog modules. The other side of the board comes with Quectel MC20 module that handles Bluetooth, GPS and GSM, a dual use micro SD card […]

Sunvell T95P Android Plug Computer mini Review

First of all, I have to say sorry for the delay for the review, but at the time I got this “beauty”, it would not power up, even though the blue light showed up out of the USB connector… I tried to recover a couple of times, no success at all… Getting a little upset, and tried after weeks of not thinking anymore… So I used an old trick, we all know, I guess. The freezer trick! I covered the Sunvell T95P in a soft linen towel, and put it in the freezer for around 3 hours. After that, it really worked like nothing happened before. There is also the old fascinating hairspray trick for “boards”… That could have been of help in some cases, but I couldn’t find a way to open this box without it being damaged for good. Here we go. Claimed Product details of T95P: 2G/8G […]
