WellcoM WePad A800 Android 2.2 Tablet Video Review

More and more decent (e.g. with capacitive multi-touch screen, decent processor…) and cost-effective android tablets are hitting the market such as Archos Gen8 Series. It might be difficult to obtain Archos 70 in some countries in Asia. But not is all lost as product such as the WellcoM WePad A800 are available in Thailand (and probably other countries). This tablet based on Qualcomm MSM7227 @ 600 Mhz runs on Android 2.2. The device comes with 512 MB DDR RAM, 512 MB Rom, a 7″ multi-touch capacitive touch screen (800 x 480) , Wifi, Bluetooth, 2G/3G network support. I discovered this product in a shop in Chiang Mai yesterday. I tried it a bit, it was very smooth and responsive. It sells for 15900 Baht (530 USD / 383 Euros) with a free bluetooth headset. The following videos (In Thai only) reviews the device. The reviewers runs a lot of benchmark […]

Accurate Time Keeping in Embedded Systems

In many embedded systems, there is a need to keep accurate time/date. This is often performed using an RTC (Real-Time Clock). However,  uncalibrated RTC are not that accurate. For example, ST Microelectronics M41T94 RTC datasheet explains that: Uncalibrated clock accuracy will not exceed ±35 ppm (parts per million) oscillator frequency error at 25°C, which equates to about ±1.53 minutes per month. . In order to improve the accuracy, you’ll need to calibrate the crystal for each board at the factory using a frequency counter, that will greatly improve accuracy, for M41T94: When the Calibration circuit is properly employed, accuracy improves to better than ±2 ppm at 25°C. However, calibrating the crystal will further increase the manufacturing costs. Another way to have a very accurate time keeping, is to use the power supply frequency (50 Hz/60 Hz) which is extremely accurate due to interoperability requirements between electricity providers. In the diagram […]

Archos 101 Archos 70 with Android 2.2

In the previous blog post about Archos 70 Video Review, I mentioned the device was running on Android 2.2. This is not currently accurate, as the device now ships with Android 2.1, but will be upgradable to Android 2.2 soon after. [ad#Google Adsense – Wide Banner] In the meantime, here’s an another Charbax’s video about Archos Gen8 devices (i.e. Archos 28,Archos 32, Archos 43, Archos 70and Archos 101) running a beta version of Android 2.2 for this series of devices.

Archos 70 Internet Tablet Video Review

Archos as just released a new 7″ Android Tablet. This device costs around 275 USD (249 Euros), which is a pretty good price for a device based on an ARM Cortex A8 at 1 GHz running Android 2.2, a capacitive touch screen (800×480), HDMI output (Up to 720p), built-in wifi (802.11n) and bluetooth 2.1 as well as a front facing camera.

Netgem Set-top-box N5000 – Toshiba Places

Mid-september, Netgem showcased their new set-top box at IBC 2010: the Netbox N5000 Internet/TV Adaptor. A modified version of this Set-top box will be used by Toshiba (Toshiba places) and be available for purchase for 99 Euros starting in October 2010 in France and later in 2011 in some other Europeans countries.

Internet TVs at IFA Berlin

Even though Android tablets were widely hyped, IFA also had other interesting devices on display. Among them, internet TV is starting to take off. I would have expected some Android set-top box to be shown off, but some manufacturers may prefer to attend IBC 2010 10-14 September 2010. Interestingly the 2 videos below only provide integrated internet Tvs, i.e. without external set-top box. Philips demo’ed an improved version of Net TV, a standard for internet television. Here’s the LG’s Smart TV system for Web-TV and apps on High Definition Television. They have a really cool “magic” remote. (Wii-like remote). This is still a prototype but it looks promising.
