IBM has developed a biochip-based one-step point-of-care-diagnostic test that uses capillary forces to analyze samples of serum, or blood, for the presence of disease markers in rapid time. [...]
One of the best uses of electric double-layer capacitors (EDLCs), also known as ultracapacitors or supercapacitors, is in the design of hybrid power supplies. The primary supply can be a battery, an a[...]
This white paper examines the speed vs. accuracy trade-offs involved in making multi-channel measurements with a digital multimeter (DMM) and relay switching in addition to the practical consideration[...]
A big Keanu "Whoa" over these gorgeous 3D renderings of fractals. The article offers a fascinating back story about the 20-year quest to adequately display a Mandelbulb, such a 3D analog rende[...]
The Microbe Motel is the grossest, smelliest, nastiest science kit we've ever offered. Ever! Other than some common household items, the Microbe Motel includes everything you need to grow colorful, s[...]
For some of us trying to sharpen our PCB layout skills, the right way to handle digital/analog ground planes can be a bit of a confusing topic. Eric Archer points out this straightforward article o[...]
A couple of weeks ago, I wrote about Virgil England's life-size dragon skeleton installation in Alaska's Chugach National Forest. A lot of readers were curious about the elaborate back-story that[...]
