LibreELEC (Kodi Linux) on Voyo V1 VMac Mini Apollo Lake Mini PC

I’ve just posted Voyo V1 VMac Mini review with Windows 10 this morning, and at the end I mentioned I quickly tried to run Ubuntu 16.04 without success. Reader Piotr who also happens to be a LibreELEC together with about 65 other team members, noticed it, provided me a link to a development version of LibreELEC 8.0 (mirror link) working with Apollo Lake processors, and explained Ubuntu was not working because Linux needs updated Mesa and Intel drivers. The image is based on Linux 4.10-rc5 with the necessary drivers and Kodi 17. The changes were mostly made by FernetMenta (Rainer Hochecker), and will be merged in Linux 4.10 and Mesa 17.0. He also implemented 10-bit HEVC support that will officially be available in Kodi 18 only and found in daily builds. So let’s try this out. After downloading LibreELEC-Intel.x86_64-8.0-devel-20170130110609-r25167-gd210441.img.gz, I tried to flash it (N.B.: no need to extract it) […]

NovaVGA Shield Adds VGA Output to Arduino Boards

Arduino boards are convenient to control I/Os, link LEDs, and display info on small LCD displays, but if you want to output data to a larger monitor, it’s a bit more complex. NovaVGA shield for Arduino simplify the task of outputting data to a VGA monitor over SPI. NovaVGA shield hardware specifications: CPLD – Xilinx XC9572XL CPLD, user programmable via JTAG interface. SRAM Framebuffer – 160×120 pixels @ 6-bit color (2^6 = 64 possible colors) VGA Output – 640×480 @ 60Hz physical resolution (25.175MHz pixel clock) Interface with MCU – SPI mode 1 interface (consumes only three Arduino pins) Header pins not included MicroNova provides an Arduino library with various examples such as color palette, Mandelbrot, Tetris and text console, as well as a user’s guide and PDF schematics that can all be downloaded directly on the product page. NovaVGA shield sells for $29 on Tindie or directly on MicroNova […]

Voyo (V1) VMac Mini Apollo Lake Mini PC Review – Part 2: Windows 10

Voyo VMac Mini, also sometimes referred to just Voyo V1, is an actively cooled mini PC powered by Intel Celeron N3450 or Pentium N4200 Apollo Lake processor. I’ve received samples for both, and already taken pictures of the device and motherboard. So in the second part I’ll review the mini PC checking out system info, running some benchmarks on both, and see how it performs as an entry-level desktop PC. Voyo VMac Mini Setup and System Information Setup is pretty straightforward, as you just need to connect mouse and keyboard, Ethernet, the mini HDMI to HDMI cable, optionally the included USB WiFi dongle, the power supply, and finally press the power button to get to Windows 10 desktop logged in as “admin” user in about 30 seconds. Some Apollo Lake mini PCs support HDMI 2.0 video output, but this requires a DisplayPort to HDMI 2.0 bridge chip, which not included […]

Satechi USB Type-C Power Meter Measures up to 65 Watts

CHARGER Doctor is a popular USB power meter for USB 2.0 ports that can help you check whether your charger delivers the promised amperage, and if you are dealing with USB powered device you can easily measure the power drawn by that device. But we are now in 2017, and USB type C has become more and more popular, and can deliver higher voltages higher than 5V, as well as higher currents. So if you are looking for USB type C power meter, Satechi has you covered. Satechi USB-C power meter key features and specifications: Voltage Range – 4V-20V Current Range – 50mA-10W Max readable Power – 65W Indicates power over time (mAh) and current direction (e.g. charger to laptop, or laptop to phone). USB 3.1 data pass-through supported Dimensions – 6.3 x 2 x 0.8 mm Weight – 8.6 g Beside just measuring power usage, several blogs report this USB-C […]

Lenovo Yoga Book 2-in-1 Hybrid Laptop Features a Drawing Pad instead of a Keyboard, Ships with Windows, Android or DOS

Lenovo has launched yet another 2-in-1 hybrid laptop, but the Yoga Book has some interesting new feature as it does not come with an actual keyboard, but instead a large “Create Pad” (Wacom digitizer) that allows you to draw sketches, take notes, and yes, it can also be converted into a virtual keyboard too when needed. Lenovo has a $499 version with Android 6.0, and another one with Windows 10 for $549, but I initially found it on GearBest, selling the device for $642.91 shipped with DOS operating system instead to give the user the option to install his/her own choice of operating system. Lenovo Yoga Book specifications: SoC – Up to Intel Atom x5-Z8550 quad core Cherry Trail processor System Memory – Up to 4 GB LPDDR3 Storage – Up to 64 GB internal storage, and micro SD slot supporting up to 128 GB Display – 10.1″ IPS LED […]

Add a 2.5″ Hard Drive to Voyo VMac Mini mini PC with a $20 Custom SATA Cable

When I tore down Voyo VMac Mini mini PC, I noticed a 2.5″ mounting mechanism, and some weird 9-pin SATA connector, but since the hard drive would be so close to the components I assumed this specific case was not designed for a drive, but the board would be compatible. However, it’s now possible to purchase a $20 custom SATA cable from “Voyo Official Store” on Aliexpress to do just that.All you have to do is to open the case, connect the cable to the motherboard, and the hard drive, and mounting the hard drive to the mechanism with four screws. I’m not sure whether you should also use some kind of insulation between the drive and motherboard, as it will be really close, but the company does not mention anything about that. Cooling might also be an issue even though there’s a fan in the mini PC. It’s not […]

Voyo VMac Mini mini PC Benchmarks with Intel Celeron N3450 Apollo Lake Processor

Following up yesterday’s post about Voyo VMac Mini mini PC benchmarks with Intel Pentium N4200 processor, I’ve switched to its cheaper little brother powered by Intel Celeron N3450 processor and performed the same benchmarks to compare the performance difference with the Pentium version, as well as older Braswell and Cherry Trail systems. I’ve run HWiNFO64 before running the benchmarks to get more details about computer, and especially the processor. Celeron N3450 is a quad core processor clocked at 400, 800, and 1,100 MHz, and up to 2.2 GHz in burst mode. It’s quite similar to Pentium N4200, except the later has a higher burst frequency (2.5 GHz), and a better GPU with 18 EU, instead of just 12 EU on the Celeron. My exact version of the processor is stepping B0/B1 with sSPEC SR2YA/SR2Z6. I forgot to comment about supported features compared to Cherry Trail and Braswell processors yesterday, and […]
