Magicsee C300 is a $70 DVB-T2/C & DVB-S2 Android Set-Top Box Powered by Amlogic S905D SoC

Amlogic S905D processor is an evolution of Amlogic S905X with Gigabit Ethernet support, and TS interfaces for digital TV tuners. That explains why most devices launched with the processor come with tuners. So far, we’ve covered or reviewed a few including Sen5 STB (2x DVB-T2/C), Mecool KI Pro (T2/S2), and TX95D TV box with a single DVB-T2 tuner. Magicsee C300 is another Amlogic S905D Android STB that comes with DVB-T2/C (Terrestrial & Cable), and DVB-S2 (Satellite) tuners, and sells for just under $70 on Aliexpress, and can be found on other shops such as GearBest. Magicsee C300 specifications are quite similar to the ones for Mecool KI Pro: SoC – Amlogic S905D quad core ARM Cortex-A53 @ up to 1.5 GHz with penta core Mali-450MP GPU System Memory – 2 GB DDR3 Storage – 16GB eMMC flash + micro SD card slot up to 32GB Video Output – HDMI 2.0a […]

Tronxy X3S 3D Printer Review – Part 3: Upgrades to Fix Bed Leveling Issues (Permanently)

Karl here. I have had the Tronxy X3S 3D printer for a while now. It prints well but as I mentioned in previous articles I had to level for every print. Actually near the end I would just overpower the stepper motors while the skirt was printing and level. Leveling front to back was not affected. Only the z height. So this worked but it was frustrating. Before that I tried several different things to mitigate. I thought maybe the endstop for Z homing was inconsistent and replaced it. I tried heating the bed for extended period of time thinking that maybe some thermal expansion. Didn’t help. I finally did a major change to the X carriage with success. I even moved the printer to our local library and the bed stayed leveled for a demo. I call this a success, and will show how I did it. Inspiration for […]

First OpenCL Encounters on Cortex-A72: Some Benchmarking

This is a guest post by blu about his experience with OpenCL on MacchiatoBin board with a quad core Cortex A72 processor and an Intel based MacBook. He previously contributed several technical articles such as How ARM Nerfed NEON Permute Instructions in ARMv8 or OpenGL ES development on Ubuntu Touch. Qualcomm launched their long-awaited server ARM chip the other day, and we started getting the first benchmarks. Incidentally, I too managed to get some OpenCL ray-tracing code running on an ARM Cortex-A72 machine that same day (thanks to pocl – an LLVM-based open-source OCL multi-platform implementation), so my benchmarking curiosity got me. The code in question is an OCL (half-finished) port of a graphics demo from 2014. Some remarks of what it does: For each frame: a single thread builds a sparse voxel octree from a dynamic voxel scene; the octree, along with current camera settings are passed to an […]

Texas Instruments MSP430 Value Line Sensing MCUs Sell for 25 Cents and Up

Texas Instruments MSP430 16-bit mixed signal microcontroller has been around since at least 2004, and the last time I played with the MCU was with eZ430-Chronos wireless watch development kit in 2011. Over the years, the company has added more parts to its MSP430 MCU portfolio, and they recently added two new MSP430 Value Line Sensing MCUs that offer up to 25 functions (timers, I/Os, reset controller, EEPROM…) for as low as 25 cents, as well as a new MSP430FR2433 LaunchPad development kit . MSP430FR2000 and MSP430FR2100 MCUs have the same features set, except for the memory (512 vs 1024 bytes): 16-Bit RISC Architecture up to 16 MHz Memory / Storage MSP430FR2000 (new) – 0.5KB of Program Ferroelectric RAM (FRAM) + 512 Bytes of RAM MSP430FR2100 (new) – 1KB of Program FRAM + 512 Bytes of RAM MSP430FR2111 – 3.75KB of Program FRAM + 1KB of RAM MSP430FR2110 – 2KB of Program FRAM + 1KB of RAM Supply Voltage […]

Colorful C.J1900A-BTX Plus V20 Bay Trail Motherboard Takes 8 Graphics Cards for Cryptocurrency Mining

Intel Bay Trail processors are mostly found in tablets, 2-in-1 hybrid laptops, and mini PCs, and they’ve often give placed to Cherry Trail processors, and in some cases Apollo Lake ones. x86 compatibility, low cost and low power are the main selling points of the Bay Trail processor family. Colorful has found a different use case, as they designed a motherboard with 9 PCIe x16 slots, one for a card powered by an Intel Celeron J1900 processor, and 8 to add graphics card in order to mine cryptocurrencies. The blue PCI slot takes a PCI CPU card with an the following specifications: SoC – Intel BayTrail J1900 quad core processor @ up to 2.42 GHz with 2M Cache, integrated Intel HD graphics; 10W TDP Memory – 1×DDR3L SO-DIMM, DDR3L 1333MHz/1066MHz Storage – 1x mSATA slot, 1x SATA 3.0 connector, 1x 4-pin SATA connector Video Output – HDMI Connectivity – Dual […]

Linux 4.14 Release – Main Changes, ARM & MIPS Architecture

Linus Torvalds has announced the release of Linux 4.14: No surprises this week, although it is probably worth pointing out how the 0day robot has been getting even better (it was very useful before, but Fengguang has been working on making it even better, and reporting the problems it has found). Sure, some of the new reports turned out to be just 0day doing things that just don’t work (ie KASAN with old gcc versions, but also doing things like loading old ISA drivers in situations that just don’t make sense – remember when you couldn’t even ask if the hardware existed or not, and just had to know), but even then it’s been all good. The appended shortlog is obviously only for the (small) haul since rc8, and it really is tiny. Not very many commits, and they are small. The biggest thing that stands out in the diffstat […]

NanoPi Fire2A & Fire3 Boards Released with Samsung/Nexell Quad & Octa Core Processors

FriendlyElec previously launched NanoPi 2 Fire board powered by Samsung (Nexell) S5P4418 quad core Cortex A9 SoC, mostly interesting because of its small form factor, camera and LCD interfaces. The company has now launched two new boards based on S5Pxx18 processors, namely NanoPi Fire2A powered by S5P4418 SoC, and NanoPi Fire3 based on S5P6818 octa-core Cortex-A53 SoC. Both boards share the same form factor, which remains quite similar to the one of NanoPi 2 Fire, except the HDMI connector now makes place for a micro HDMI port, the USB 2.0 has moved into vertical position, and a few other tweaks have been made to positions of buttons and components. NanoPi Fire2A / Fire3 specifications: SoC Fire2A – Samsung S5P4418 quad core Cortex A9 processor @ up to 1.4GHz, Mali-400MP GPU Fire3 – Samsung S5P6818 octa core Cortex A53 processor @ up to 1.4 GHz, Mali-400MP GPU System Memory Fire2A – 512MB DDR3 […]
