Hanoi Hackerspace site is dead.
After few years of trying to build a hackerspace in Hanoi to promote make culture. We failed to secure a space to host the hackerspace and gather core group of makers. Later Eoin Kinsella and I have moved away out of Hanoi city.
Now it is up to other projects like FabLab Hanoi and Hackanoi to carry on the torch.
Do you want to develop add-on's for Firefox? Mozilla's Add-on SDK let's you create Firefox add-ons using standard Web technologies: JavaScript, HTML, and CSS. Recently I stumbled across Alexander Saladrigas's videos tutorials that teach Firefox add-ons development with Add-on SDK. The videos introduce you to the tools for creating, running, testing and packaging add-ons and working with buttons, panels and tabs.
Thank you Alexander for making these videos. Hope to see more from you in future.
"All the technology in the world can't help you see a good picture" - John Greengo
For many years I traveled without a camera. Looking at the world, observing the people and the events. Becoming more aware of my surroundings and training my eye to see a good picture. The lack of camera removed the need to look through the lens or worry about the technicalities of photography.
Michael Freeman's The Photographers Eye is great way to continuing my training. The book teaches the fundamentals of design, composition, light and process of photography. The book is written in a simple jargon free language with some beautiful pictures. If you want to become a good photographer, do read and assimilate this book. It is *must* read for every aspiring photographer.
Hong Kong and Shenzhen are mecca for hardware enthusiasts. In my previous blog post I shared about buying Arduino in Hong Kong. Let me share some more information about sourcing electronic components in Hong Kong and Shenzhen.
Dim Sum Labs Hong Kong's hacker space maintains a local guide to buy electronics on their Resources page.

Happy shopping!
It's my turn on stage. Smiling broadly I walk over to the stage with my computer. I worked hard on my slide-deck and pre-loaded all the webpages just in case the Internet connectivity failed. Connect my computer with a VGA cable to the projector and realize that I need to mirror my screen. So that the audience could see my computer screen on projector. That should be easy to do. So I open my computers display settings on Gnome control center and hunt for the 'mirror the screens' option. I can feel scores of eyes follow my every move. There is no option to mirror the display screens, I break into a cold sweat. I regret not saying a prayer to the demo gods.
Miracles happens, my fellow presenter Yang was my guardian angel. He had one trick up his shelve. He took the computer and typed this magic command into the terminal.
xrandr --output VGA1 --same-as LVDS1
That worked! I wipe the sweat and thank Yang profusely. Now it's show time.

Few people asked for information about the time-lapse photography in my last blog post about 3D printing hamster castle. In this blog post, I'll share how to do time-lapse photography with Sony RX100 II camera.
The Sony RX100 MKII doesn't have a built-in intervalometer. So we'll use an Android device with Timelapse app to take photographs at regular intervals. Also we'll power the the camera and the Android device with a wall charger so that they don't run out of battery during the long time-lapse recording. The Sony RX100 MKII can be charged directly using a standard mini-USB power adapter. That means I don't have to replace the batteries during the long time-lapse.
First, let's turn off the power saving mode on the camera. This prevents the camera from going into sleep mode. To control the camera using a Android device, navigate to your cameras 'Control with Smartphone' menu option. Once selected, the screen will display camera's Wi-Fi SSID and password (Read the Sony documentation about Wi-Fi Direct here). Now go the WiFi settings on your Android device and connect to 'Direct-XXXXX' WiFi access point with the password displayed on your camera. Once connected, Open 'Timelapse' app and select 'RX100 mk2' from the camera model drop down menu. Next you can select the interval for your time-lapse (I used 10 secs for this time-lapse) and start your recording. Please make sure that the Android device is near to the camera to avoid losing the WiFi connection. The camera takes the pictures and saves them to SDCard. What's next? You can now use a video program of your choice to turn this time-lapse photographs into a video on your computer.
Please don't forget to share your experiences doing time-lapse photography.
