BenQ Joybee GP1 mini Projector review

Posted by Charbax – May 31, 2009

Review showing this very compact and light 3LED projector, one of the first in the world with built-in USB host functionality to playback DivX mpeg4 files from a USB flash memory or from a FAT32 formatted hard drive. It has great colors and performs great for its size. Having a built-in USB reader means you can play movies on it directly without the need to use a computer or a video player device to playback the video formats. Yet the BenQ Joybee GP1 mini projector does not yet support Mp3 audio nor AC3 audio in DivX/XviD Mpeg4 files, thus audio contents has to be re-encoded mostly thus far to the PCM or the AAC format. BenQ can update the firmware so I will update this description if I hear any confirmation by them that they are adding Mp3 audio support on it.

These type of super compact 3LED projectors are getting cheap enough, bright enough, sharp enough, with very nice colors and easy to use enough so I think that it may become a very popular product.

Archos 5 TV Snap-On review

Posted by Charbax – May 25, 2009

Review of the Archos 5 TV Snap-On accessory that let's you watch and record DVB-T (freeview) signals city-wide and country-wide for most European countries which already have good DVB-T coverage. It comes with a dual diversity antenna system that allows you to get the best reception for a mobile DVB-T receiver, it picks in real-time the best available signal while you walk around or move your device around when at the football match, at work, in school, on the bus, on the train, anywhere especially in densely populated areas which have good DVB-T coverage.

Archos 2 review

Posted by Charbax – May 25, 2009

Review of the Archos 2 mp3 player, the current cheapest mp3 player with 4GB ($39), 8GB ($59) and 16GB ($99) having such a nice color 1.8" LCD screen for videos and pictures. It's main selling point is that it's much cheaper than the competing devices by Sandisk, Dell, and Apple's ipod nano.

ARM and Android, the future of laptops

Posted by Charbax – April 1, 2009

The main goal of the OLPC, and thus, of the whole computer industry at this point, is to lower the cost of laptops by lowering the power consumption. The best way to achieve that, is to limit the way applications get full native access to the deep internals of the computer system. Intel’s X86 standard and Microsoft’s Windows OS were designed only for that multi-purpose backwards compatibility where the same unoptimized bloated software would work across thousands of hardware configurations with often full root access to the deepest internals of a computer system. For most of the applications that most people need, you do not need full native code support in third party applications. By limiting full native access for third party applications, you take care in one swoop of all the security problems that one has on Intel and Microsoft based PC and laptops. You basically make spyware, viruses, hacking and all of those problems impossible by design.

That is how Android is made. Android provides a totally sandboxed JAVA-based software layer, which only interacts with the hardware features through totally controllable software-to-hardware APIs. With Android on ARM, you have a complete shift in the way third party applications are run compared to X86 Windows XP/7, MacOSX and even most of those X86 Desktop Linux distributions that have been going around, including Ubuntu and Fedora.

The open source native Android Linux code hacking happens exclusively at the manufacturer stage. Which means, you want to have a manufacturer in control of everything, you want the manufacturer to customize Android for the very specific mass produced hardware in question, providing all the standard and non-standard software-to-hardware APIs for third party software developers to gain access to the all of the devices standard or special hardware features.

What you have backing Android is the worlds absolute best company in Google, comprised of the worlds largest concentration of PHDs and Engineers with the most experience in Web and computer technology. The role of Google with Android is to make sure that the native Android code works in the most optimal fashion with the most optimal hardware configurations that manufacturers are making for it. Google helps manufacturers prepare that Android native code customization for each different System On Chip, for each different variation on the ARM Cortex processor profiles by each of the industry leading ARM processor manufacturers among Texas Instruments, Qualcomm, Broadcom, Freescale, Samsung, Nvidia, Marvell and others.

If you want to change the default Android user interface layer and make it look more like the Sugar User Interface layer (which for XO-1 was built on top of an optimized X86 Fedora Linux installation), you definitely can do those changes and customizations. Those would come from the manufacturers, thus in the case of OLPC from the whole OLPC organization, in cooperation with Google or anyone else helping to create a more education-laptop friendly user interface. But Android applications remain the same, and appart from slight porting that can be required, all Android applications are designed to work in full screen mode, and management of multi-tasking, notifications, memory and processing power consumption, all those are managed the same way accros all implementations of the Android OS.

HP has just announced that they are working to support Android in future HP Laptops. Asus has also announced to be working on Android laptops. Look forward to Android ruling over all ARM Laptop implementations, at least for these where the lowest cost and the lowest power consumption levels have been achieved. Look forward to $100 Android ARM laptops. Look forward to the empire of Intel and Microsoft crumbling under the inevitable hardware and software revolution that comes with the XO-2 and with the whole industry’s shift to lower cost, lower power consumption using ARM and Android in all laptops.

Hanvon Touchscreen E-Book

Posted by Charbax – March 19, 2009

Hanvon shows a 5" touchscreen E-Ink E-Book reader device. The size of the screen I think could be perfect for the device to be pocketable, if they can just remove all the unecessary screen bezel before the release of this product. The touchscreen feature using the special stylus has also a huge potential in terms of building software features for it once the device is connected to the Internet using WiFi or HSDPA, to enable readers to collaborate online on editing texts, on commenting and building communities of handwritten annotations around texts. A USB or Bluetooth keyboard could then be connected to enter typed annotations as well.

ARM in OLPC XO-2

Posted by Charbax – January 29, 2009

OLPC is probably looking for a non X86 architecture for XO-2, probably ARM, where several providers can provide the processor. Using ARM Cortex, OLPC can use any of Texas Instruments, Mavell, Freescale, Samsung, Qualcomm, Nvidia and others, all interchangeably, independently of the deals that will be put in place. The idea being that having all these ARM Cortex providers being more or less compatible with each other, enabling minimal changes in motherboard designs to have them all be compatible, this enables competition in the processor market. This will more quickly drive the prices down much further. This is the only way you can optimize the interpretation of Moore’s law which says that you can cut the price and power consumption of laptops by half every 18 months.

There is a basic reason AMD is not too enthusiastic about this whole new low cost laptop market. The reason is written on the wall, everyones can see it coming, cheaper laptops means it will be much harder to find profits in the industry. AMD isn’t exactly having an easy time already as things are today, Intel’s profit margins and overall income have shrinked 90% in 2008 compared to 2007.

I believe OLPC should use Google Android with Sugar on top, and they should increasingly rely on cloud computing such as the recently rumored Google Web Drive service to store and share all the data on. With XO-2, you should much further synchronize the way the school servers synch storage, processing power and contents to and from the cloud. Basically what you get is an overly simplified Internet access terminal, one with a small ARM Cortex processor behind the next generation of even lower power and lower cost Pixel Qi screens. One that just relies on basic Google Gears for local content caching, and let most of the rest happen using the much cheaper cloud.

$100 laptops using ARM are possible today already. Chinese GPS manufacturers are making them already using uber simple Linux and last generation MIPS or ARM processors: http://techvideoblog.com/category/laptops/

This makes it obvious that OLPC can achieve a $75 price point on XO-2, consider also the advantage of using a dual touch-screen, is that ou can even more easilly mass manufacture exactly the same model for the whole world. Since all the different keyboard layouts and all of the local interfaces are simply going to be a software function of the touchscreens. Mary-Lou Jepsen has done it once already. She can do it again.

My next HD camcorder should have these features

Posted by Charbax – August 2, 2008

- WiFi and HSDPA built-in to upload my HD videos directly to an FTP server without needing to use a laptop. API to interact with online services to then publish that video to video-blogs and Youtube.

- Live streaming using WiFi or HSDPA of the camera feed in a low resolution and bitrate all the while the camcorder is recording the HD quality to the Internal storage.

- Built-in 2.5" hard drive (up to 500GB) as well as SDHC storage.

- Built-in bluetooth or VHF to use for cheap but high quality wireless microphones. Multiple microphones should work with one camera.

- USB keyboard support to enter filenames, description, tags for when publishing the HD videos directly from the camera to the Internet.

- Voice recognition service (could be online), can automatically transcribe title, description and tags from voice recordings made to be linked up with the main HD video file recording.

- On screen live chat from live video viewers in the same way as the Qik live chat works on the Nokia N95.

- Live video feed should be able to go to services such as Qik.com, Mogulus.com, Ustream.tv, Kyte.tv as well as live p2p streaming systems using live Bittorrent protocols, pplive or sopcast.
