Maker Education is such a valuable role. These stories will bring you the latest information and tales of maker educators who area spreading the maker mindset. Help others learn how to make things or how to think like a maker at makerspaces, schools, universities, and local communities. The importance of maker education can not be understated. We appreciate our educators.
In this, the fourth installment of Engineer Guy Series #4, Bill, Patrick, and Nick show off the engineering that accounts for three key characteristics of laser light: single wavelengths, narrow beams, and high intensities. Highlights include laser retinal surgery, the difference between phosphorescence and fluorescence, and a rather more sophisticated treatment of laser physics than is common in popular science.
In this off-the-cuff video, MIT prof and MAKE pal Gregory Charvat shoots Nerf darts into the beam of an old X-band Doppler radar gun with its output hacked into a linear power supply, a preamp, and finally into Greg’s living room stereo system. The signal sounds like a cartoon sound effect!
At issue is free public access to scientific information gathered using tax dollars. Which, in the US, is about a third of it. If you’ve ever been hot on the trail of a technical lead and run up against a robot demanding $40 to download one four-page, thirty-year-old journal article, you know what I’m talking about.
I’m following along as Erin “RobotGrrl” Kennedy continues to build the vintage Heathkit voltmeter she unboxed earlier this month. Now she’s continuing the build! Last part we unboxed the Heathkit, looked at all the components, and started to build some of it. Now it’s time to finish off the build with the three main plates. […]
As much as I love Engineer Guy videos, I am especially partial to Series #4, because it is themed around the chemical elements—each installment features a different element and a remarkable bit of engineering based upon it. And this week my two personal favorite elements are in the spotlight. Though it is utterly common, today, […]
Here, with great fanfare, is the second installment of Engineer Guy Series #4: theMEMSaccelerometer. With typical flair, Bill and his production team take us from the basic concept of an accelerometer (using the familiar ball-on-a-spring model), through the analogous silicon device that lets your smartphone tell up from down, all the way to the anisotropic etching techniques used to It’s wonders all the way down, with Bill, as usual.
Bill Hammack is back! I am pleased beyond measure to present the first video in Engineer Guy Series #4, in which Bill Hammack and his Engineer Guy production team at the University of Illinois unravel the key technology of digital photography: the charge-coupled device.
