This video is excellent, because it helps draw young girls’ attention to the possibilities of engineering. Maybe after seeing the video, they’ll ask their parents for a Goldie Blox kit or try to build a Rube Goldberg machine in their living room. Maybe they’ll learn, as all engineers do, that a successful project means educating yourself in math and physics; that you need to know exactly how far apart to place each domino to make sure your train falls down at an even, consistent rate.

If you are doing some data logging, sensor reading or other routine task with raspberry Pi, then you probably are thinking of using database. The list of database software choices is quite long, but in most cases you will end with single or few tables in database. First thought might be MySQL – well known database server in WWW. Anyway this is pretty heavy tool to have running on Raspberry Pi.
In my opinion SQLite is probably most suitable choice. Because it is serverless, lightweight, opensource and support most SQL code. Another handy thing is that SQLite stores data in single file which can be stored anywhere. Continue reading
Raspberry Pi Model B comes with Ethernet interface built in where you can plug cable and have internet access. In many cases this is enough, but what if you want it to be more portable and still be able to connect to it? One solution would be using Wi-Fi adapter.

You can get them in very compact size that aren’t that good at sensitivity and range or choose bigger ones with antenna. No matter what type you select – all of them works pretty same way.
For my experiment I am going to use cheap Wireless adapter EDUP model EP-N8508. It supports all necessary features and standards that are needed to have WiFi. Small form factor makes it attractive to use on many devices like Laptop and so on Raspberry Pi. You may need to use powered USB hub to get reliable performance. For now I am using it attached to one of USB ports directly. Continue reading
