A Day at Chiang Mai Maker Party 4.0

December 6th, 2017 6 comments

The Chiang Mai Maker Party 4.0 is now taking place until December 9, and I went there today, as I was especially interested in the scheduled NB-IoT talk and workshop to find out what was the status about LPWA in Thailand. But there are many other activities planned, and if you happen to be in Chiang Main in the next few days, you may want to check out the schedule on the event page or Facebook.

I’m going to go though what I’ve done today to give you a better idea about the event, or even the maker movement in Thailand.

Booth and activity area should be the same over the 4 days, but the talks, open activity, and workshop will be different each day. Today, people could learn how to solder in the activity area.
The even was not really big with manufacturers/sellers like ThaiEasyElec, INEX, or Gravitech closer to the entrance…


… and slighter higher up in a different zone, companies and makers were showcasing their products or projects. I still managed to spent 5 interesting hours at the event attending to talks and checking out the various projects.

I started my day with a talk entitled “Maker Movement in South East Asia” presented by William Hooi, previously a teacher, who found One Maker Group and setup the first MakerSpace in Singapore, as well as helped introduce the Maker Faire in Singapore in 2012 onwards.


There was three parts to talk with an history of the Maker movement (worldwide), the maker movement in Singapore, and whether Making should be integrated into school curriculum.
He explained at first the government who not know about makers, so it was difficult to get funding, but eventually they jump on the bandwagon, and are now puring money on maker initiative. One thing that surprised me in the talk is that before makers were hidden their hobby, for fear of being mocked by other, for one for one person doing an LED jacket, and another working on an Iron Man suit. The people around them would not understand why they would waste their time on such endeavors, but the Maker Space and Faire helped finding like minded people. Some of the micro:bit boards apparently ended in Singapore, and when I say some, I mean 100,000 units. Another thing that I learned is the concept of “digital retreat for kids” where parents send kids to make things with their hands – for example soldering -, and not use smartphone or tablets at all, since they are already so accustomed to those devices.

One I was done with the talk, I walked around, so I’ll report about some of the interesting project I came across. I may write more detailed posts for some of the items lateron.

ASUS Tinker board to handle fall detection, and an NVIDIA Jetson board for artificial intelligence. If fall is detection an alert to send to the tablet, and the system also interfaces with Xiaomi Mi band 2.

Katunyou has also made a more compact product, still based on Tinker Board, for nursing home, or private home where an elderly may live alone. The person at the stand also organizes Raspberry Pi 3 workshops in Chiang Mai.

I found yet another product based on Raspberry Pi 3 board. SRAN is a network security device made by Global Tech that report threats from devices accessing your network using machine learning.

Nordic Technology House showcased a magic mirror based on Raspberry Pi 3, and a webcam to detect your dance move, but their actual product shown above is a real-time indoor air monitoring system that report temperature, humidity, CO2 level, and PM 2.5 levels, and come sent alerts via LINE if thresholds are exceeded.

One booth had some drones including the larger one above spraying insecticides for the agriculture market.

There was also a large about sewing machines, including some smarter one where you can design embroidery in a table before sewing.

There were also a few custom ESP8266 or ESP32 boards, but I forgot to take photos.

The Maker Party is also a good place to go with your want to buy some board or smart home devices.

Beside Raspberry Pi Zero W / 3, ESP8266 boards and Asus Tinker board seem to be popular items in Thailand. I could also spot Sonoff wireless switch, and an Amazon Dot, although I could confirm only English is supported, no Thai language.

BBC Micro:bit board and accessories can also be bought at the event.


M5Stack modules, and Raspberry Pi 3 Voice Kit were also for sale.

Books are also available for ESP32, Raspberry Pi 3, IoT, etc… in Thai language.

Click to Enlarge

But if you can’t read Thai there was also a choice of book in English about RPi, Arduino, Linux for Makers, IoT and so on. I then attended the second talk of the day: “NB-IoT” by AIS, one of the top telco company in Thailand. Speakers included Phuchong Charoensub, IoT Marketing Specialist, and Pornsak Hanvoravongchai, Device Innovation Manager, among others. They went through various part include a presentation of AIS current M2M business, what IoT will change (e.g. brings in statups and makers), some technical details about NB-IoT, and the company offering for makers.

I’ll go into more details in a separate post tomorrow, but if you want to get started the good news is that it’s now possible to pre-order a 1,990 THB Arduino Shield ($61) between December 6-9, and get it shipped on February 14, 2018. NB-IoT connectivity is free for one year, and will then cost 350 Baht (around $10) per year per device. However, there’s a cost to enable NB-IoT on LTE base stations, so AIS will only enable NB-IoT at some universities, and maker spaces, meaning for example, I would most certainly be able to use such kit from home. An AIS representative told me their no roadmap for deployment, it will depend on the business demand for such services.

If you are lucky you may even spot one or two dancing dinosaurs at the event.

Meet the First Windows 10 Arm “Always Connected PCs” – HP Envy x2 (2017) and ASUS NovaGo TP370

December 6th, 2017 28 comments

Qualcomm and Microsoft showcased some Snapdragon 835 based Windows 10 “Mobile PCs” at Computex 2017 last June, and while the press was allowed film the demo, the device could only be operated by a Qualcomm employee.

But both companies and their partners have made progress, and at the Snapdragon Technology Summit, Qualcomm announced “Always Connected PCs” which will run Windows 10, be always on and always connected at Gigabit LTE speeds, and support all-day battery life while keeping thin and fanless designs. all while incorporating Windows 10. HP and ASUS unveiled their very own “Always Connected PCs”, respectively Envy X2 and Novago TP370. What I used to call laptop or in this case 2-in-1 hybrid (laptop) is now apparently called “Always Connected PC”, but in any case let’s have a closer look at both devices.

HP Envy x2 (2017)

Specifications:

  • SoC – Qualcomm Snapdragon 835 Mobile Processor @ 2.6GHz with Adreno 540 GPU @ 710MHz
  • System memory – Up to 8GB RAM

The 2-in-1 laptop always connected PC will run Windows 10 S by default, but a recommended free upgrade to Windows 10 Pro will be offered. More details may be found on the product page. Windows 10 S only allows the installation of apps in Windows Store, and Microsoft own Edge browser (no Firefox, no Chrome), so most people will likely upgrade to Windows 10 Pro, especially if it is free, and this is probably a condition imposed by Microsoft.

ASUS NovaGo is expected to be available early next year, while the HP Envy x2 is planned for Spring 2018. I could not find pricing on the official page, but Liliputing reports an “entry-level model with 4GB of RAM and 64GB of storage should sell for about $599, while an 8GB/256GB model will run $799”.

You’ll find various hands-on video for the Envy x2 (2017) model online, including the one from Engadget embedded below.

Asus WA039T All-in-One PC is Powered by Intel Pentium J4205 Apollo Lake Processor

August 16th, 2017 No comments

Intel Pentium N4205 is the most powerful Apollo Lake processor launched by Intel with four cores up to 2.6GHz (turbo), and 18 EU HD graphics, but so far I have not seen many products with the processor, with only ASRock J4205-ITX motherboard and Beebox J4205 mini PC. So I went to Aliexpress, and nothing at all shows up for J4205, I had better luck on Alibaba with Unistorm / ACEPC AK1 mini PC apparently also having Pentium N4205 as an option (for OEM only), and several industrial computer and motherboards. But none of those products seem to be easily purchasable just yet. A final search on GearBest led me to their one and only J4205 based product: Asus WA039T AIO PC, so let’s have a look.

Asus WA039T AIO computer specifications:

  • SoC – Intel Pentium J4205 quad core “Apollo Lake” processor @ 1.50 / 2.60 GHz with a 18 EU Intel HD Graphics 505 @ 250/800 MHz (10W TDP)
  • System Memory – 4GB DDR3 (upgradeable to 8GB)
  • Storage – 1TB hard drive, SD card slot
  • Display – 21.5″ LED display with 1920×1080 resolution, 16:9 aspect ratio
  • Video Output – HDMI output
  • Audio – Via HDMI, 3.5mm headphone jack, built-in dual channel speaker, microphone
  • Webcam – Yes
  • Connectivity – Ethernet, 802.11b/g/n/ac WiFi
  • USB – 4x USB 3.1 ports
  • Power Supply  – TBD
  • Dimensions – 51.40 x 16.50 x 39.80 cm
  • Weight – 4.5 kg

The AIO PC runs Windows 10. I was unable to find any references to WA039T on asus.com.

Asus WA039T is sold on GearBest for $683.93 including free shipping. [Update: Use coupon GBTPC to bring the price down to $595.02]

Linux 4.12 Release – Main Changes, ARM & MIPS Architectures

July 3rd, 2017 6 comments

Linus Torvalds has just released Linux 4.12:

Things were quite calm this week, so I really didn’t have any real reason to delay the 4.12 release.

As mentioned over the various rc announcements, 4.12 is one of the bigger releases historically, and I think only 4.9 ends up having had more commits. And 4.9 was big at least partly because Greg announced it was an LTS kernel. But 4.12 is just plain big.

There’s also nothing particularly odd going on in the tree – it’s all just normal development, just more of it that usual. The shortlog below is obviously just the minor changes since rc7 – the whole 4.12 shortlog is much too large to post.

In the diff department, 4.12 is also very big, although the reason there isn’t just that there’s a lot of development, we have the added bulk of a lot of new  header files for the AMD Vega support. That’s almost exactly half the bulk of the patch, in fact, and partly as a result of that the driver side dominates  everything else at 85+% of the release patch (it’s not all the AMD Vega headers – the Intel IPU driver in staging is big too, for example).

But aside from just being large, and a blip in size around rc5, the rc’s stabilized pretty nicely, so I think we’re all good to go.

Go out and use it.

Oh, and obviously this means that the merge window for 4.13 is thus open. You know the drill.

Linus

Linux 4.11 provided various improvements for Intel Bay Trail and Cherry Trail targets, OPAL drive support, pluggable IO schedulers framework, and plenty of ARM and MIPS changes.

Some of the most notable changes in Linux 4.12 include:

  • Initial AMD Radeon RX Vega GPU support
  • BFQ (Budget Fair Queuing) and Kyber block I/O schedulers have been merged, meaning the kernel now has two multiqueue I/O schedulers suitable for various use cases that should improve the responsiveness of systems.
  • Added AnalyzeBoot tool to create a timeline of the kernel’s bootstrap process in HTML format.
  • Implemented “hybrid consistency model” for live kernel patching in order to enable the applications patchsets that change function or data semantics. See here for details.

MQMaker MiQi & ASUS Tinker Boards Get Linux 4.11 with 3D Graphics Acceleration

May 2nd, 2017 8 comments

One day after the release of Linux 4.11, developer Miouyouyou” has released Linux 4.11 for Rockchip RK3288 platforms such as MQMaker MiQi and ASUS Tinker boards with some patchsets for ARM Mali r16p0 kernel drivers, ARM fbdev, and to improve performance.

The kernel has been tested with the Mali User-space r12p0 drivers for fbdev and wayland written for Firefly-RK3288, and some OpenGL ES 3.1/3.2 samples could successfully run on the board. 3D graphics acceleration does not work in X11 however.

Miouyouyou also plans to add support for Rockchip VPU code, as well as ARM gator, and document how to use ARM DS-5 Streamline for OpenGL ES 2.x/3.x debugging.

If you have a MiQi or Tinker board running Debian, you can try the kernel by adding beta.armbian.com Debian repository to your apt source file, and installing the following packages:

ASUS Tinker Board’s Debian & Kodi Linux Images, Schematics and Documentation

January 24th, 2017 43 comments

We discovered ASUS Tinker Board powered by Rockchip RK3288 processor earlier this year via some slides hidden in a dark corner of the Internet… ASUS has been incredibly quiet about it, but as the board has finally started to sell in Europe on sites like CPC Farnell UK, Proshop (Denmark), or Jimm’s (Finland)  for the equivalent of $57.5 without VAT or $69 including VAT, and more technology sites have started to write about it.

So people have been buying the board, and one even uploaded an unboxing video. One interesting part is the the top comment from the uploader in that video:

Currently, a £55 paperweight as I can’t seem to find a link to the OS image anywhere.

And indeed, ASUS appears to have launched a board without any support website, firmware image and documentation. Maybe that’s why they are quiet about it. But after using some of my voodoo search skills, I finally found firmware images for the board, as well as the schematics, and some other documentations on Asus website. [Update: New official link with the same files as of today (27/01/2017)]

There are currently 10 documents & files for download on the site:

  • Operating System Images – TinkerOS DEBIAN & TinkerOS KODI images
  • Hardware Docs – Tinker Board Schematics (PDF only), 2D & 3D Drawings
  • Software Docs – GPIO API for Python & C,
  • Other documents
    • Qualified Vendors List for devices tested with the board include micro SD cards, USB drives, Bluetooth headsets (A2DP), headphone amplifiers, Bluetooth keyboards & mice, HDMI TVs & monitors, AC adapters, Ethernet dongles, flash disks, and WiFi routers
    • Tinker Board FAQ overview
    • CSI & DSI configuration explaining how to use an external display and/or camera.

Note that there may be a reason why ASUS has not officially published the images yet: they might consider them alpha or beta (TBC).

ASUS Tinker Board is a Raspberry Pi 3 Alternative based on Rockchip RK3288 Processor

January 5th, 2017 50 comments

Regular readers may remember MQMaker MiQi board, a $35 (and up) development board powered by Rockchip RK3388 quad core ARM Cortex A17 processor, based on Raspberry Pi 3 form factor, but much faster according to benchmarks. Sadly, the board’s crowdfunding campaign was not that successful, possibly because of the “its’ a 2-year old processor” syndrome. But now, Minimachines has found that ASUS has designed a very similar board, dubbed Tinker Board, with an extra WiFi and Bluetooth LE module, audio jack, MIPI DSI connector, and a few other modifications.

The company targets education, maker, and IoT markets for the board, with applications ranging from mini PC to portable game console and RC products like drones. The board supports Debian with Kodi.

asus-tinker-board-vs-raspberry-pi-3ASUS also provided a quick comparison table with Raspberry Pi 3 model B, that mostly shows the advantages over the Tinker board. The table is mostly fine, and I got some Phoronix benchmarks showing RK3288 can be about three times as fast as BCM2837 processor for FLAC audio encoding. The last row with officially supported OS appears to show both boards on the same footings, but Raspberry Pi 3 model B will have a clear advantage here, although I’m not sure why Asus did not list Android OS support for their board. The table does not include any price information either.

The only information I could find was from the Slideshare presentation above, and there does not appear to be any official website or page on Asus website.

[Update: ASUS Tinker board can now be purchased on Amazon or Aliexpress]

Thanks to Freire for the tip.
