Wintel W8 Review – Dual Boot Android & Windows TV Box

Wintel W8 (aka Kingnovel K8) is an Intel Atom Z3735F mini PC inspired from Sunchip Wintel CX-W8 (the hardware is a little different), but instead of just running Windows 8.1, the device can dual boot Android 4.4 and Windows 8.1 with Bing. I’ve already taken pictures or torn down Wintel W8, so today, I’ll focus on the software part of the review, first checking dual boot functionality and Windows 8.1 briefly since it should be very similar to MeLE PCG03, before spending more time on Android as it’s my first Android Intel platform. Dual boot in Wintel W8 When you boot the device, you can select Android or Windows icon, with a 10 second timeout that will boot your latest choice. There’s no menu within Windows to start Android, and vice versa, so to dual boot you need to reboot first, and select the operating systems right after UEFI. The […]

Improve Mediatek MT6752 GPS Accuracy by Turning WiFi Off?

Mediatek smartphones used to have a terribly slow GPS fix, and it would often take over 10 minutes to get a fix if any, and one workaround was to enable Mediatek EPO. However, in my Iocean M6752 review, I found out GPS fix was not super fast even without Internet connection, but accuracy is quite a disaster as Nike+ Running screenshot below clearly shows. I’m running around a stadium so the shape should be elliptic…, but data point are all over the place. Since the review, I’ve kept using the smartphone with Nike+ Running, and each time it’s a disaster, and once the app even reported a 81 km for an actual 10 km run… I’ve also used Google Maps once or twice, and found accuracy to be poor as well. However, I usually leave Wi-Fi on, and for some reasons today, I decided to turn Wi-Fi off before driving […]

UDOO Neo Combines Arduino, Raspberry Pi, Wi-Fi, Bluetooth and Sensors into a Single $49 Board (Crowdfunding)

UDOO Neo was unveiled last February as the first hobbyist board features Freecale i.MX6 Solox Cortex A9 + Cortex M4 processor. I was expecting UDOO to design support board since their earlier UDOO board combined Freescale i.MX6 processor with an Atmel MCU, and the new processor allowed for integrating the same functionality into a single chip. The board is now on Kickstarter where you can pick UDOO Neo Basic for $49 (Early bird is $35), or UDOO Neo for $59 (Early bird was $45) adding an Ethernet port, some sensors, and 1GB RAM, instead of 512 MB for the Basic version. But both versions of the board basically share the same specifications: SoC – Freescale i.MX 6SoloX ARM Cortex-A9 core @ 1GHz with 2D/3D GPU and ARM Cortex-M4 Core @ 166 MHz System Memory – 512MB (Basic) or 1GB DDR3 Storage – micro SD slot, 8-bit SDIO interface (on expansion headers) […]
