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 […]

YokaTV KB1 Android TV Box is Equipped with Two HDMI 2.0 Inputs

We’ve seen in the past some TV boxes with one HDMI input such as Zidoo X9 or EWEAT R9 Plus in order to record an external video source, and possibly use some other features like PiP or video UDP streaming. However, I’ve recently become informed that YokaTV KB1 Android TV boxes, powered by an Amlogic S905X, and not one, but two HDMI 2.0 input ports, on top of its HDMI 2.0a output port. YokaTV KB1 specifications: SoC – Amlogic S905X quad core ARM Cortex A53 processor @ up to 1.5 GHz with an ARM Mali-450MP GPU System Memory – 2GB DDR3 Storage – 16GB eMMC flash *4 to 32GB flash optional), micro SD slot up to 32GB Video Output – HDMI 2.0a up to 4K @ 60 Hz, 3.5mm AV jack (composite) Video Input – 2x HDMI 2.0 ports Audio Output – HDMI, AV (stereo audio), and optical S/PDIF Connectivity […]

Voyo VMac Mini mini PC (Intel Pentium N4200) Benchmarks

Since I’ve now received Intel Apollo Lake hardware with Voyo VMac Mini mini PCs, I’ve going to run some benchmarks with Pentium N4200 and Celeron N3450 processor to compare the performance against older generation low power mini PC based on Braswell and Cherry Trail processors. I’ll get started with the Pentium N4200 version that’s both more expensive and powerful. But before starting with the benchmarks, I’ve run HWiNFO64 to get a bit more info about the system, and the processor in particular. The processor is the quad core Pentium N4200 stepping B0/B1 with sSPEC SR2Y9/SR2Z5 clocked between 400 and 1,100 MHz, and up to 2,5 GHz in burst mode. It also comes with a 18 EU HD graphics Gen9-LP. IMHO, PCMark 8 Home Accelerated 3.0 is one of the best benchmark as it replicates typical use cases such as web browsing, video conference, light gaming, photo editing, and so on. […]

Checking Fan Noise and Other Sound Levels with Benetech GM1352 Sound Level Meter

I wrote about UNI-T UT353 Sound Level Meter a few months ago as I thought it could be a neat way to measure fan noise on some TV boxes and mini PCs in an objective way. I finally ended up buying Benetech GM1352 model instead for $13.9 on DX (now available for $12.83 on Aliexpress or around $18 on Amazon), but I did not really use it so far, since I did not get a new device with a fan. I’ve now had the chance to try it since the Voyo VMac Mini mini PC comes with a fan. Let’s just go through some of GM1352’s key features first: Noise Levels & Accuracy – 30 to 130 dB with +/- 1.5 dB accuracy (94dB @ 1 KHz) Frequency Range – 31.5 to 8 KHz Measurement features – MAX/MIN & Data hold Display – 1.7″ LCD display with backlight Buttons – […]

Ebox T8 V Octa-Core Android TV Box Review – Part 2: Android Firmware, EBMC, and Benchmarks

EBox T8 V (version 5) is the new EntertainmentBox.com TV box specially geared towards the UK market with its choice of apps and online shop based in the United Kingdom. It’s an upgrade to EBox T8-4 I reviewed last year, replacing Amlogic S905 quad core processor by Amlogic S912 octa-core processor, but keeping most of the same features including the SATA bay and EBox user interface. Since we’ve already checked out the hardware, likely based on Zoomtak U Plus, I’ll focus on the firmware in the second part. It will be a shorter reviewed than usual since I have already tested many Amlogic S912 TV boxes, and I’ll refer to T8-4 review when the user interface is identical, and instead focus on what has changed, and the usual suspects like audio pass-through, 4K video playback, DRM support, WiFi performance, etc… EBox T8 V Setup Wizard, Setup, OTA Firmware Update, and […]

Review of Voyo VMac Mini PC with Celeron N3450 / Pentium N4200 SoC – Part 1: Unboxing and Teardown

I received my first Apollo Lake device yesterday with CHUWI LapBook 14.1 laptop, and today I got two more with Voyo VMac Mini powered by Intel Celeron N3450 processor sent by GeekBuying, and the version powered by the more powerful Pentium N4200 processor sent by GearBest. I’ll start by checking out the hardware today, before reviewing one of the models, and comparing performance through benchmarks for both mini PCs a little later. Voyo VMac Mini Unboxing Both packages look identical, but the N3450 model has a sticker with basic specs, while the N4200 model did not have anything to indicate which model I received. However, GearBest left a paper inside the package confirming they sent the N4200 version. When I first read the markings on the package, I read “Mac Mini” instead of “VMac Mini”, so if you happen to live in a country where customs care about those things, […]
