I just built Android Cardboard DIY Virtual Reality Headset of which I mentioned in the blog two weeks ago. Here is my DIY version. I had to make some changed to lens holding part, because the lenses I had were a little lit larger than the ones the headset was designed to use (not too →
Today’s HTML5 tips are two simple but useful (for testing and small tasks) on-line tools. real-time HTML editor! is as simple as it can get HTML editor. The editor show two frames: Type HTML in the upper textarea above, and the resulting HTML page will magically appear in the frame below. real-time HTML editor! suits →
I have read more than year ago (2012) interesting articles about Digilent‘s Analog Discovery Kit. I even quickly tried the WaveForms Software the cames with it (freely available and testable without hardware). It looked interesting, but I decided that maybe I don’t at the moment need this and skipped it (I did not even write →
We need to talk about SPEAKERS: Soz, ‘audiophiles’, only IT will break the sound barrier article is interesting reading on audio design, DSPs and the debunking of traditional hi-fi. It says that today’s loudspeakers are nowhere near as good as they could be, due in no small measure to the presence of “traditional” audiophile products. →
When you have a great service like IFTTT that you can interface with many ready available cloud services or commercial hardware, the next idea is how to connect your own device (Arduino, Raspeberry Pi, etc..) to this service. Here are some pointers to ideas how to interface your own hardware to IFTTT: Pushbullet’s IFTTT Channel →
I have last year written about USB soldering irons starting with USB soldering iron posting that introduced the idea. I followed with DIY USB soldering iron posting that gave ideas how to make your own instead of buying a ready made product. Now it is time for an updateon this topic. Element 14 Ben Heck →
This is a very cool service I found when looking at news on Internet of Things (IoT): IFTTT (short for “If This Then That”) is a service that enables users to connect different web applications (e.g., Facebook, Evernote, Weather, Dropbox, etc.) together through simple conditional statements known as “Recipes”.

Want a virtual reality headset, but can’t afford the hefty pricetag on most existing models ? (Too expensive toy?). Google dropped an inexpensive solution following its I/O keynote: Google Cardboard, an app that lets Android users transform their phones into VR headsets with the help of a DIY cardboard viewer. This is interesting. The parts →
