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!

Using snow to see heat transfer

In these photos, you can see the heat transfer happening through a number of roofs in my neighborhood. In a wintery time like we have now, the snow acts as an indicator of your insulation. If you have a full roof of snow, then you’re well insulated. If you have spots of bare roof surrounded by snow, then inside the house is an area where it’s uninsulated, or poorly insulated. If your roof doesn’t hold the snow at all, then it’s time to look at your attic insulation. Sunny, South facing roofs will naturally clear faster on clear days, due to the input of solar energy.

Spacewalkers take tinkering to new heights

Spacewalkers take tinkering to new heights

Astronaut Bob Behnken participates in a spacewalk during STS-123. Image courtesy of NASA. Imagine having your workshop traveling at 17,500 miles per hour more than 200 miles over the Earth as you work through grueling, painstakingly-planned out steps of a project with specialized gadgets like a massive Pistol Grip Tool. STS-130 mission specialists, Bob Behnken […]

Robots versus pirates!

Robots versus pirates!

A Russian firm is selling a system of ship-mountable auto-targeting water-pumping robots with the dual purpose of fighting fires and repelling pirates. BotJunkie’s Evan Ackerman explains:

The robotic water cannons (six on each side of the ship) are controlled by a central computer, using TV cameras to target pirates approaching the ship. The robots shoot streams of water at 40 liters per second out to a range of 70 meters, and can wash away potential boarders and even sink small boats. This is a defensive technique that is already used against pirates, but having robots do the shooting helps keep the people who would otherwise be wielding the fire hoses safe.

My biggest concern with this system would be that the pirates could use their Electro-Bolt plasmids to temporarily short out the automated turrets, then hack them to turn against their masters. I mean, just looking at them, it’s pretty clear these things are based on Rapture-style hydro-tube technology.

Trilo-femoral-mechnicus

There’s plenty of bad found-object and “junk” sculpture in the world. I know because I made most of it myself. But Jud Turner, whose skeletal “Bio-Cycle” made some waves when we posted about it last year, does it right. He’s recently posted a bunch of new work to his website, e.g. the awesome mecha-trilobite shown above.
