A visit to the HMS Beagle science store
While in town for the Kansas City Mini Maker Faire, we had the chance to visit the HMS Beagle, which is a gem of a science store located in Parkville, Missouri.
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!
19th century Terminator arm found in hydraulic press
Well, OK, it’s actually a prosthesis. And I stole the Terminator joke from Minnesotastan over at Neatorama. This object is one of literally thousands of remarkable items in the online Brought to Life exhibit at the UK’s Science Museum, where it is labeled, apparently incorrectly, as a “right” arm. What is it with surgeons confusing left and right appendages?
Garden trowel from hot-formed PVC pipe
A trowel is such an inexpensive tool, it’s hard for me to imagine making my own for anything besides the experience of making and having made it myself. Still, I can see why someone might want to make this one described by Instructables “PVC whisperer” Thinkenstein: It starts from ubiquitous scrap material, looks good, and is made using an unusual process that involves softening PVC pipe under heat (a delicate trick, safety wise) and forming it by hand.
MAKE 23: How to shoot mosquitoes with lasers
Huge problem: Malaria kills millions, but you can’t just spray DDT anymore to wipe out disease-carrying mosquitoes (DDT also wipes out, oh, majestic bald eagles). What do do? You could search for another toxin to spray. Or, if you’re 3ric Johanson at Intellectual Ventures Laboratory, you could invent a new gadget. A gadget that tracks […]
2000V washer launcher
Bob Davis, whom some of you may remember for his high-voltage can crusher, is back at it with this 2KV, 1600A, 1500 μF 10-capacitor discharge bank that can be used to crush cans and, most amusingly IMHO, launch washers high into the air with a sound that really has to be heard to be appreciated. Bob’s video might benefit from a bit of editing; clicking the embedded player above should take you right to the money shot around 4:35. There’s also a good can-crushing right around 5:50.
How-To: Liquid-Cooled Carseat
Instructables user kstruve writes: I currently live in the Phoenix, Arizona area, which gets mighty hot in the summer. This summer, we’ve had several days around or above 110 degrees. I have twin baby boys, and despite cracking the windows, using reflective seat covers and running the A/C full blast when driving them around, their […]
Math Monday: Mathematical needlepoint
By George Hart for the Museum of Mathematics Continuing our fiber arts theme of past weeks, today’s Math Monday offers an excellent example of mathematical needlepoint. This piece illustrates a Hilbert curve, taken to the sixth approximation. The continuously changing color of the thread makes it easy for your eye not to lose its place […]
