Superglue: AMA-Recognized Maker Ouch-Aid

Firefly Workshop’s Craig Smith described how he seals small wounds with the help of superglue: I read that the American Medical Association now recognizes superglue as a medical aid. For cuts that are deep, but not requiring stitches, or in an area where stitches are tricky, superglue is used. Funny thing was that I had [...]

Unusual Copper Oxide Thermopile

Nyle Steiner of SparkBangBuzz never fails to impress with his old-fashioned hand-on approach to electronics. Whether he's improvising memristors from bits of junk he picked up off the ground, building audio oscillators using blobs of...Show More Summary

Artificial Leaf Splits Water Molecules When Exposed to Light

This solar-cell device mimics the ability of a leaf to convert sunlight into usable energy. It’s the brainchild of a team led by MIT’s Daniel G. Nocera, working in conjunction with researchers at SunCatalytix, a company Nocera founded. The device is based on two water-splitting photocatalysts developed by Nocera’s group. Simply dropping the solar cell [...]

Secret Santa: John Edgar Park – All-Glass Steam Still

Back in 2009, my colleague John Park published his Florence Siphon coffee brewing apparatus in MAKE Volume 17. That's him, above, goggling up before disengaging the safety interlocks on his infernal machine. I have had the pleasure of...Show More Summary

Top 10: Tips for the Amateur Chemist

We have featured projects from teenage chemist Hayden Parker, who is this semester an entering freshman at Willamette University, several times since he first showed up on our radar at Bay Area Maker Faire 2011. We recently asked Hayden...Show More Summary

How-To: Green Lantern. Literally.

No power rings are involved, here, just boric acid, methanol, and a homemade spirit lamp. It's all nicely explained by Instructables user The Green Gentleman.

How-To: Homemade Memristor

Fascinating video from Nyle Steiner, who reports on his experiments with simple homemade memristors made from what are, probably, Al-CuS-Cu and Al-PbS-Pb junctions. He describes the observations that led him to experiment with theseShow More Summary

How-To: Supercheap Glycerin Fogger

YouTuber HouseholdHacker shows just how simple a glycerin-based fog machine really is, in principle, and how easy is it is to improvise a pretty fair substitute with some food-grade glycerin, a candle, and a couple other odds 'n' en...

Maintaining a laboratory notebook

Collin Purrington offers some great tips on the necessity of maintaining a laboratory notebook. While directed mainly at scientists, I could see it applying to anyone interested in Open Source Hardware development or simply working on difficult, long-term projects. [Via @cenmag] In the Maker Shed: Pick up The Maker’s Notebook ($19.99) for all your big [...]

How-To: Anodize Aluminum Without Strong Acid

If you've ever wanted to experiment with aluminum anodizing but were put off by the conventional requirement for concentrated sulfuric acid, you will be very interested to read of Ken's successes with an alternate process using the acidic sodium salt of sulfuric acid. Show More Summary

Drawing Circuits in Conductive Ink

Materials researchers at the University of Illinois, Urbana-Champaign have developed a highly conductive silver ink. In this video, Analisa Russo, a graduate student in the research group of Professor Jennifer Lewis shows exactly how to make this amazing ink, which could be used for a wide variety of hobby projects and in advanced electronics hardware. [...]

FDM Printing With Polycarbonate

Rich was curious about printing with polycarbonate (PC), but couldn't find any definitive answers to his questions online. So he bought a roll of 1.6mm PC filament and started experimenting, and his reports are fairly glowing. PC melts hotter than ABS or PLA, is more rigid, and comes out of the printer cloudy, which some have suggested may be due to atmospheric moisture.

DNA Makers: Dawei Lin (video)

Dawei Lin studies DNA at UC, but also started building Lego models of DNA as a teaching tool for his young daughter. At Maker Faire Bay Area 2011 he displays the various DNA models he's made, while explaining that the act of construction can often be the most valuable learning tool for many different topics.

What Carbonated Acrylic Plastic Looks Like

As I wrote about a month ago, one of the many unusual phenomena Ben Krasnow has produced in his garage is supercritical CO2. As you may recall, Ben machined a custom acrylic pressure vessel so he could get (and give) a good look at a state of matter that most of us have little experience of. Show More Summary

Backyard Chemistry at Maker Faire Bay Area

With over 200,000 views, Hayden Parker’s YouTube channel has become a popular spot for watching home chemistry demonstrations. Hayden took his show on the road to Maker Faire Bay Area 2011, where he set up a basic chemistry lab, teaching the science of chemistry and wowing passerby with seemingly magic color-changing chemical reactions.

Tips for Preserving Plastic Artifacts

Though "plastic" has now largely overcome its "The Graduate"-era connotation of “necessarily cheap, fake, and ephemeral,” it remains the case that plastic objects—especially those manufactured early in the history of plastics technology—present unusual challenges for long-term conservation.

Using Liquid Paint Stripper as Acrylic Cement

Unless your application is critical, cheap liquid paint stripper from the hardware store (not the gel, paste, or color-changing varieties) is a fine substitute for commercial acrylic solvent cement. Comparing one MSDS to another, weShow More Summary

How-To: Clear Glass Circuit Boards

Interesting homebrew process from Charles Lohr, who demonstrates it here with a multicolor-LED-controlling capacitive touch sensor that works from the reverse side of the glass, i.e. you can use it without actually touching the copper. No holes are drilled in the glass, so all components have to be SMT. Cool stuff.

What Supercritical Carbon Dioxide Looks Like

At extremes of temperature and pressure above a substance's so-called "critical point," the distinction between liquid and gas phases of that substance stops being meaningful, and the substance enters a homogeneous "supercritical" phase. Show More Summary

Compressed: Ferrofluid and Bubbles

Kim Pimmel of San Francisco, CA, created this “experimental art video of ferrofluid and bubbles.” I combined everyday soap bubbles with exotic ferrofluid liquid to create an eerie tale, using macro lenses and time lapse techniques. Black ferrofluid and dye race through bubble structures, drawn through by the invisible forces of capillary action and magnetism.
