$50 UNI-T UT61E Digital Multimeter Supports Data Logging to a Windows Computer

Since I don’t use a multimeter that often, and don’t need high precision, I bought an ultra cheap multimeter (Sunwa DT830B) locally a couple of a years ago. I normally use it for continuity testing (no beep though) for repair work / checking solder point, and some quick voltage measurement, and it works well for these simple tasks, although the lack of buzzer makes it a little inconvenient. But I discovered its limits when I tried to measure current. The 200 mA range works fine, but I started to encounter issues when switching to the 10A range, as device under tests would just start rebooting if the current draw was too high, and the manual indicates that you “cannot measure more than 15 seconds in the 10A range”. Since I did not want to spend $100+ on a Fluke multimeter, I did some research for a better multimeter, and finally […]

MT87 Digital Clamp Multimeter Hands On

When you want to measure power/current on electrical device, a kill-a-watt is the easiest method, but it’s not always possible for items like air conditioner, water pumps, etc… because they may simply be no plug to disconnect. Luckily, current clamps are made just for this purpose, where you simply place one of the two wires in a clamp / loop, and it magically measures the current. You can’t put both wires inside the loop or measurement will not work at all. The good news is that such devices are very inexpensive, and I bought MT87 digital clamp multimeter, which is also a multimeter adding voltage and resistance measurement capability, for just $11.33 on DealExtreme. MT87 comes with measurement leads (voltage/resistance only), and a user’s manual. The linked user’s manual is not exactly the same document, but very similar, and also refers to MT87C model which adds temperature measurement. There are […]

MXQ S85 Android TV Box (Amlogic S805) Review

MXQ S85 (aka MXQ OTT TV box) and EM6Q-MXQ are two main Full HD H.265 Android media players based on Amlogic S805 currently selling on Chinese online stores. I’m lucky enough to have received both, and I’ve already completed the review for EM6Q-MXQ, so today I’ll complete MXQ S85 review and compare both devices. I’ve already taken picture of the device, accessories, and checked out the board’s components in my unboxing post, so in this post, I’ll focus on the user interface, evaluate performance, and test most hardware features of this media player. First Boot, Settings and First Impressions I’ve started by a quick test of the IR remote control, and it works as expected after inserting two AAA batteries, before switching to Mele F10 Deluxe air mouse for convenience. I’ve connected all ports of the device except the S/PDIF output: Ethernet cable, HDMI and AV cables, micro SD card, […]

Can Rockchip RK3288 Android TV Boxes Play Videos at True 4K UHD / 2160p Resolution?

[Update 2: Now that I have a 4K TV, I’ve redone the test myself, and Rockchip RK3288 can play 4K videos properly. The mistake was to use Software decode in MX Player which renders to the framebuffer instead of the video buffer. Visit the post entitled 4K Output and Video Playback Capability Tested on 6 ARM based mini PCs and Boards for details.] [Update 1: The post has now been updated, after it was clear one of MX Player options was misunderstood. The conclusion remains the same] Over the last few years there have been complains about Android TV boxes decoding 1080p video, rendering them to a 720p frame buffer, and upscaling them back to 1080p resolution for video output, so you ended up playing 1080p videos at a real 720p resolution. I never investigated the issue in details, and thanks to new media players now coming with a 1080p […]

Unboxing of MXQ S85 Android Media Player Powered by Amlogic S805 Processor

Gearbest sent me MXQ S85 Android media player powered by Amlogic S805 quad core processor with 1GB RAM, 8GB internal storage, and Ethernet/Wi-Fi/Bluetooth connectivity. MXQ S85 looks very similar to EM6Q-MXQ, another Amlogic S805 based Android STB, which I reviewed last week, but these are two distinct hardware platforms. Today, I’ll take some pictures of the devices, and the board to see which components are used, and who made the board, and I’ll write a full review in a few days. MXQ S85 Pictures I’ve received the parcel via DHL in the nameless package below where they just indicate it’s and Android TV box with a quad core processor, quad core GPU, pre-loaded with XBMC, and supporting HEVC / H.265 The package contains the box, HDMI and AV cables, an OTG adapter, a 5V/2A power supply, an IR remote requiring two AAA batteries, and a user’s manual in English. The […]

Current Performance and Stability Issues on AllWinner A80 OptimusBoard Development Board

Sine A80 OptimusBoard is the first ARM hardware that supports both USB 3.0 and Gigabit that I’ve ever owned, so I though it might be interesting to see what performance I could get with a USB 3.0 hard drive through the USB 3.0 OTG port of the board. For testing purpose, I bought a USB 3.0 OTG adapter on Ebay, but I did not look closely enough as it turned out to be only a USB 3.0 OTG to USB 2.0 female adapter capable of USB 2.0 speeds… Kind of useless item since you can plug a standard USB 2.0 OTG adapter into a USB 3.0 OTG receptacle. But I tried my hard drive anyway, and quickly realized write performance was very poor at 3 MB/s on the NTFS partition, whereas most other devices can handle at least15 MB/s, and usually over 25 MB/s. So I contacted Allwinner with this […]

Review of Tronsmart Orion R28 Meta 4K/H.265 Android TV Box

It’s been a little while since I unboxed Tronsmart Orion R28 Meta Android TV box, but since the product was still consider “beta” by GeekBuying, I wanted to wait for a OTA firmware update (109k4), which was released at the beginning of the week. Since I’ve already listed the technical specifications, and showed pictures of the board and device, I’ll focus on feature tests and benchmarks results in the review. First Boot, Settings and First Impressions I quickly tried the basic infrared remote control, inserting two AAA batteries, and it does the job, but for Android, you really need a pointing device, so I switched to Mele F10 Deluxe air mouse during testing. I’ve connected a whole bunch of cable, and peripherals to the box including an HDMI cable, a USB hard drive, an Ethernet cable, a USB webcam, and a USB hub with RF dongles for my air mouse […]

Review of Nagrace HPH NT-V6 Android Mini PC Powered by RK3288 with 4GB RAM, 32GB Internal Storage

Last week-end, I finally received TP-Link TL-WDR7500 router (Chinese variant of Arched C7) router, so I could complete my review of Nagrace HPH NT-V6 including 802.11ac Wi-Fi. I’ve already listed the specifications, and taken a few pictures of the device and the board, and today I’ll focus on the test results. I’ll start by giving my first impressions, going through the user interface and settings, before testing video playback, as well as benchmarking networking, storage and overall system performance, playing some games, and testing most hardware features of this mini PC. First Boot, Settings and First Impressions A simple infrared remote control is provided with the device, and I’ve quickly tried it by inserting two AAA batteries, and it works fine, but for the rest of testing I switched to Mele F10 Deluxe air mouse to control the device, as it’s much more user friendly than any IR remote. Before […]
