4Duino-24 is an Arduino compatible 2.4″ Color IoT Display Module with Atmel MCU and ESP8266 Module

I played with ITEAD Studio NEXTION serial color displays for Arduino boards and the likes a few months ago, and while the hardware seems good and the company offer a large choice of 2.4″ to 7″ models at a very affordable price, I didn’t find the Windows software to create the user interface to be very user-friendly. 4D Systems, an Australian company specializing in “graphics solutions”, will soon launch a similar 2.4″ display, but integrated into an Arduino compatible board also featuring an ESP8266 module for WiFi connectivity. 4Duino-24 “LCD  IoT Display Module” specifications: MCU – Atmel ATmega32U4 micro-controller with 32KB flash, 2.5KB SRAM, 1KB EEPROM Storage – micro SD card slot (FAT16 support) for data and logging WiFi Module – ESP8266 based with 802.11 b/g/n connectivity, 1MB flash, support for Wi-Fi Direct (P2P), soft-AP Display – 2.4” LCD-TFT resistive touch display module with 240×320 resolution, 65K colors, and powered […]

How to Resolve Slow Boot Times in Ubuntu 16.04

I’ve recently upgraded my machine from Ubuntu 14.04.4 to Ubuntu 16.04.1, but while my computer used to boot in about 40 seconds, after the upgrade boot times increased considerably to 2 to 3 minutes. The first easy check was to look at dmesg:

There’s a bit 87 seconds gap between checking for the floppy, and VirtualBox drivers loading. So there’s definitely an issue here, but the log does not exactly give a clear queue. I’ve read you could use systemd-analyze to find which process(es) may be slowing down your computer at boot time:

Two processes are taking close to 8 seconds, but those 16 seconds still do not explain why it takes 2 minutes more to boot…Eventually, I realized systemd-analyze has a few more tricks up its sleeves:

The first command shows there’s no problem with the kernel itself, and something is slow in user space. The […]

Tanix TX5 Pro TV Box Review – Part 1: Unboxing, Teardown, and Hands-on

Karl here with Tanix TX5 Pro S905X review. This is my first s905x box. I am splitting this into 2 parts because software is not quite up to snuff yet. I ran into some issues with language reverting back to default which is Chinese. This happens so frequently it is unbearable. I can almost read Chinese now. Youtube only shows green square with audio, and finally most apps show incompatible in the Play Store. I have notified Gearbest who is going to contact the manufacturer. On the bright side I am very pleased with UI compared to the s905 boxes I have reviewed. Specs pulled from GearBest Website General Model: TX5 Pro Type: TV Box GPU: Mali-450 System: Android 6.0 CPU: Amlogic S905X Core: 2.0GHz,Quad Core RAM: 2G ROM: 16G Max.

Inside LG 4K TV, and My (Unsuccessful) Attempt at Repairing It

Long time readers of this blog may remember that I organized a crowdfunding event aiming at raising funds to buy equipment to test 4K TV boxes and mini PCs in early 2015, and one of the items I ended up purchasing was LG 42UB820T 4K television. It worked well for over a year, but I started to notice a single vertical appear on the TV in June, or about 18 months after purchase. A few more lines appeared in the following week, and it appears to have stabilized as shown in the picture below. While I understand that in Europe a 2-year warranty period is legally required, I’m based in Asia, and all I got was a one year warranty for the TV. So I had three choices: Ignore the problem Pay for the repairs Try to repair it myself So far, I’ve selected solution 1. because that’s the easiest […]

How to Customize Amlogic Android Firmware – A Tutorial with NEXBOX A95X (S905) TV Box

CNXSoft: Bear in mind that there are multiple versions of Nexbox A95X. Yesterday, I published the review of Nexbox A95X with Android 6.0, with the model based on Amlogic S905X processor. In this article, Karl had a look at Nexbox A95X with Amlogic S905 processor, which he purchased a couple of months ago, but since he was not happy with the Android 5.1 firmware, he decided to customize it. Karl here with a review of the Nexbox A95X S905 box. This took a while to even start. I received the box about 2 months ago and I dived right in and broke it. I didn’t have factory firmware, and wasn’t cautious enough and bricked it. I found some firmware that worked but it didn’t work very well for me. Email’s to Nexbox directly didn’t help and I was stuck with a bricked box… I later found someone who had factory […]

NEXBOX A95X (Amlogic S905X) TV Box Review – Part 2: Android 6.0 and Kodi 16.1

Last week I publish the first complete review of an Amlogic S905X device with MINI M8S II TV box review, and while the device work in a smooth and stable manner, some features did not work as expect such as HDMI audio pass-through. I’ve now had the change to compare  it to another S905X with NEXBOX A95X, not to confuse with its “homonym”: NEXBOX A95X with Amlogic S905 processor. I’ve already taken pictures of the device and accessories, and checked out the hardware in the first part of the review,  so today, I’ll report my finding playing with Android 6.0 firmware, Kodi video and audio capabilities, and check whether bugs and issues found on MINI M8S II are also present in the device. First Boot, Settings and First Impressions NEXBOX A95X is really a tiny device, so it’s no surprise that it only comes with two USB 2.0 ports, and […]

What’s the Cheapest MCU? My Try: Holtek HT48R002 8-bit MCU Selling for $0.085

Somebody asked what was the cheapest MCU (Microcontroller) available on Google+, so I thought it would be fun to find the cheapest one regardless of specifications. It turns out there an older thread with this very question on StackExchange, and at the time (2011) Microchip PIC10F200 8-bit MCU with 256B RAM in SOP-23 package was the cheapest one among the answer, and somehow the price has not changed as it’s still $0.32 per unit for 1k orders. Not a bad price, but back in the days when I wrote on CD and DVD players, we had some price pressure from customers, so we looked for a cheaper microcontroller, and ended up using Holtek because of the competitive pricing. We suffered a bit during development due to incomplete documentation but eventually did the job. Anyway, I went to the Holtek website and found a “cost-effective I/O MCU” category, and HT48R002 appears […]
