Science

DIY science is the perfect way to use your creative skills and learn something new. With the right supplies, some determination, and a curious mind, you can create amazing experiments that open up a whole world of possibilities. At home-made laboratories or tech workshops, makers from all backgrounds can explore new ideas by finding ways to study their environment in novel ways – allowing them to make breathtaking discoveries!

Mr. Green: An Arduino robot

Mr. Green is an Arduino based robot built from a lot of scavenged parts, including old CD’s, a mint tin, and some cardboard. I really like the magnetic on/off switch and the custom wheels. Check out the link for a lot more detailed pictures of the robot. Mr.Green (aka Bean) Arduino based Robot – explore/avoid […]

Bee boxes explained

I remember, the first time I saw a bee box (or bee lining box), I was fascinated by all of its chambers (this one has two, others have three), lifts, sliding doors, windows, etc. It’s like something a magician might flourish onstage. But it’s not. It’s used for hunting and capturing wild bees and using […]

Magnetic levitation with Arduino

Magnetic levitation with Arduino

Mekonik used an Arduino board, solenoid coil, hall effect sensor, and some clever coding to hold a permanent magnet in mid-air – The device uses a small Hall effect sensor (SS19 from Honeywell, available for $0.50 from AllElectronics) to sense the field of the permanent magnet and uses that information to modulate the magnetic field […]

No-cost soil moisture sensor

No-cost soil moisture sensor

The Cheap Vegetable Gardner created this soil moisture sensor using nothing more than picture wall hanging hooks, a soda straw, hot glue, and some Plaster of Paris. After a little research there was the classic science class method of creating a homemade sensor by simply putting two galvanized nails in the soil and measuring the […]
