Very clever trick from next month’s issue of The Family Handyman, submitted by reader Joseph Johnson.
If you have “helping hands,” clamping wire leads against a washer, as shown, stabilizes the whole setup dramatically by connecting the two arms with a rigid member, so you can bear down a bit more with the iron without pushing things out of alignment. But the hole in the middle of the washer still allows all-round access to the junction.
If you don’t have helping hands, you can just use a washer, as shown, with a pair of alligator clips (or even small binder clips) as a pretty effective improvised workholding jig for this kind of soldering.
I visited the Arduino factory a month ago and Massimo from the Arduino team explained this vision, congrats – this is very cool, Arduino as an incubator.
Over 45 makers from Iowa, Indiana, and Missouri are converging on the Lindale Mall tomorrow, Saturday, February 25th, for the inaugural Cedar Rapids Mini Maker Faire.
The fair is being organized by Jim Jacobmeyer and other members of Epicenter (a Cedar Rapids makerspace), and the Cedar Rapids Habitat for Humanity Restore. Epicenter was founded in 2011 as a resource for area do-it-yourselfers, creatives, entrepreneurs, inventors, and free-thinkers.
The Cedar Valley Habitat for Humanity ReStore is a store for recycled, re-used, and re-purposed materials. These two organizations share classroom space and tools, and have naturally become a gathering spot for makers in the larger Cedar Rapids area.
If you’re anywhere in the vicinity, get on out tomorrow to Lindale Mall between 10am and 4pm!

The emerging story of entrepreneurs using drones to provide marketable services is fascinating to me. Small businesses have been making money by making drones themselves for quite awhile, now, but I’m just now starting to see start-ups using drones to sell services.
Aerial photography is maybe the most obvious opportunity—surveying real estate, covering sporting or other events, stalking celebrities, assessing damage after fires or other catastrophes—but there are also all kinds of potentially lucrative (and annoying) advertising and/or promotional possibilities. And that’s just scratching the surface of the possibilities of airborne drone-based services, never mind those of land-, water-, and underwater-going
An interesting case in point is Australian Simon Jardine, whose bouncing baby drone business is called Eye in the Sky. Australia is prime country for private aerial imaging services, with its relatively low population density, ongoing development, and vast, open spaces. Jardine’s photography was recently featured in a (surprisingly upbeat) Atlantic article about drones and privacy issues, and he’s got a Flickr stream full of great drone photography.

I spotted this fancy ceiling illumination in the Children’s Museum of Pittsburgh while there for the Pittsburgh Mini Maker Faire. The LEDs are connected to ribbon cables that attach to an EMSL Peggy 2 board similar to the one we sell in the Maker Shed (we sell the smaller Peggy2 LE version.)
The Peggy 2 is capable of individually addressing 625 LEDs arranged in a 25 x 25 grid. That means there should be 25 – 50 conductor ribbon cables attached to this one. I don’t know who soldered this, how long it took, or how they kept their wires straight but I’m truly impressed. Great work whoever you are!
Here are a few neat projects that were recently added to our collaborative wiki, Make: Projects. If you’ve made something awesome that the world should know about, please share your build process with the MAKE community, via Make: Projects.
Rich Reynolds explains how to get over-the-air television with a homemade TV antenna. He made it so that his wife can watch the summer Olympics. Sounds like over-the-air TV is making something of a comeback – the Wall Street Journal just published an article on the trend of supplementing online-video programming with over-the-air TV signals, as an alternative to a costly cable subscription.
My sister and I could have used this when we threw a Kentucky Derby party a couple years ago, to watch the horse race! We weren’t paying for cable at the time, so we ended up borrowing our neighbor’s, via a really long coax cable.
Tired of the constant whir of your computer’s fan? Generate some aural relief in the form of gentle bird chirping sounds, using an Arduino and a Wave Shield. Tutorial shared by RobotGrrl.
South Carolina high school teacher Todd Stowe says, “The first step in a high-altitude balloon (HAB) project is creating a device that will let you track and recover your payload. To do this, build an automatic packet reporting system (APRS) tracker. It’s not the only way, but it works and it is reliable.”
He really made that Make Project Tin look handsome!
Eric Hansen shares a technique for painting QR codes on large surfaces.
Harvey Moon wrote in with an update to his Drawing Machine art bot:
I’m sure all puns about bugs in the code have been thoroughly explored, alas.
This is a wonderful collection of black-and-white newsreel footage, assembled by the company that invented the newsreel, showing a montage of early helicopter prototypes in all their wacky and frequently-terrifying glory. It’s a highlight reel, about two minutes long, and the various clips that went into it are indexed, annotated, and available for watching in their entirety at the link below, which is a level of background detail we don’t often see in online video. [Thanks, Laura!]
