Rikomagic R1 Android Projector Review – Part 1: Unboxing and Teardown

Rikomagic R1 Android mini projector runs Android 4.4 on Rockchip RK3128 quad core processor, and the company sent me a sample for review, so today I’ll first do an unboxing, and partial teardown, before testing the projector in more details in the second part of the review. Rikomagic R1 Projector Unboxing The projector comes with a white package marked RKM R1. The bottom of the package indicated its unsurprisingly based on Texas Instruments DLP technology with a LED light, and is equipped with a touch panel and a battery. More importantly, there’s a QR code that links to R1 Setup Guide, which for once will be useful, as this device has some unique features. The projector ships with a 5V/2.5A power supply, an IR remote control, a HDMI cable, a tripod, and an adapter to make the interface between the projector box and the tripod. The top of the device […]

Official Rockchip Github Account and Wiki Launched

Following the popularity of RK3066 and RK3188 processors in 2013, a community of developers for Rockchip Linux and Android development was created with corresponding linux-rockchip github account, mailing list and #linux-rockchip IRC channel, and now most of the information can be gathered from development board manufacturers like Firefly. However, I’ve just been pointed out to some VA-API driver for Rockchip RK32xx processor, on rockchip-linux (not linux-rockhip) github account, with the following tagline: An open source software for Rockchip SoCs, This site maintained by Rockchip The only person currently registered to this account, Jacob Chen (陈豪), is a software engineer working for Rockchip, so it does indeed look to be official. The github account also links to rockchip.wikidot.com with links to communication channels established by linux-rockchip community, and lots of entries about Linux, Android, U-boot, and so on, most of which are currently placeholders. So it still looks like work in […]

Eny EVR01 Android All-in-One Virtual Reality Headset Features Rockchip RK3126 Processor

I keep reading that in order to offer a pleasant user experience, virtual reality will require high resolution displays (4K or greater), and SoCs fast enough to handle all the extra data processing requirements, but some Chinese manufacturers are instead trying to enter the low end of the market with products such as Allwinner H8vr or HA544 which are way too weak to handle 3D graphics for VR applications in a satisfying manner, but could be good enough for watching 3D and VR video. Eny Technology has gone one step further (down) with EVR01 VR headset based on Rockchip RK3126 quad core Cortex A7 processor combined with a 5″ 1280×720 display. EVR01 AIO VR headset specifications: SoC – Rockchip RK3126 quad core Cortex A7 processor @ 1.3 GHz with Mali-400MP2 GPU System Memory – 1GB DDR3 (Optional 512 MB) Storage – 8GB flash (Optional: 16GB) + micro SD slot up […]

Rockchip RK3188-T TV Sticks with 2GB RAM Are Now Selling for About $30 Shipped

It’s fun to report about the latest gadgets, but sometimes it can be a good idea to look back at older devices to find if there are any good deals out there. TV boxes and sticks based Rockchip RK3188 quad core Cortex A9 processors were clearly the most popular in 2013 and early 2014, and in many respects their performance is still quite similar to the one of recent 64-bit platforms barring new features such as H.265 and 4K video capabilities. The good news is that you can now get RK3188-T TV sticks such as CX919 or MK809IV with 2 GB RAM for about $30 shipped.

Linux 4.3 Release – Main Changes, ARM and MIPS Architectures

Linus Torvalds released Linux Kernel 4.3 last week-end: So it *felt* like the last week of the rc series was busy, to the point where I got a bit worried about the release. But doing the actual numbers shows that that really was just my subjective feeling, probably due to the kernel summit and travel back home from Korea. It wasn’t actually a particularly busy week, it’s just that the pull requests were more noticeable in the last couple of days. We had a network update and a late fix for a x86 vm86 mode bug introduced by the vm86 cleanups, but other than that it’s just a collection of various small one-liners all over. Ok, the vm86 mode thing was a one-liner too, it was just slightly more nerve-wracking because it looked scarier than it was before people (Andy) figured out what was going on. The changes from rc7 […]
