3D LED POV Mirror

“We Are with You, Mirror” is a piece by Brady Marks from VIVO Media Arts Centre that was shown at the Vancouver Mini Maker Faire. It is a 3D persistence of vision volumetric display that acts as a mirror, using four spinning Peggy 2 boards to reflect visitors movements in low resolution 3D LED glory.

Thank you to Brady for sending in the video!

BAMF 2014: Open Source Sprinkler Controls

We can’t say how many times we’ve heard people ask questions about hacking or building their own sprinkler controllers, but apparently here are the ones that everyone has been looking for. These open source hardware sprinkler controllers from Ray’s Hobby —  designed so that you can hack and build your own — look well-made and genuinely useful. There are neat irrigation (and multipurpose relay) controls, including Arduino-flavored variants as well as versions for Raspberry Pi and BeagleBone lovers.

BAMF2014: BreadBoardManiac

Not that I’m normally one to get excited about electronic breadboards, but I’ve had to change my mind after seeing these at Maker Faire. These breadboards by BreadBoardManiac are some of the finest electronics accessories that I’ve ever seen.  Not only do they snap to Lego bricks (making one heck of a cool building set), but they are also super-thin and double-sided, so that you can insert components from both sides. They suggest that you can use that feature to make multi-layer breadboards with vertical interconnects, but perhaps that is a bit of a stretch.

Their handmade limited edition wooden breadboards are perhaps even cooler, and were made available as part of this kickstarter project earlier in the year. This is what I’d expect kids in school to learn electronics with, and it sure would be nice if a production version became available in the future. It looks like there’s also a flexible breadboard under development, amongst other types.  I can hardly wait to get my hands on all of these.

Let’s file this under “intro machines.” The Makesmith CNC, currently available on Kickstarter for just $195 including everything but the Dremel tool. It makes very clever use of appropriate technology: Three tiny hobby servo motors, modified for continuous rotation, turn gears that turn the lead screws (well, all-thread) to drive the XYZ stage. An magnetic encoder monitors the rotation, making a high-resolution, closed-loop control system.  No bushings, melamine-coated MDF parts, Arduino control.  Planned for future open source hardware+software release, too.

Perfect?  Nope, but the creators of the project seem to be keenly aware of its abilities and limitations (many discussed here), and oh does it have affordability on its side.

The 2014 Bay Area Maker Faire was an amazing, amazing event. We took hundreds of photos, which we have posted in a flickr set here. Here are just a few of the highlights— both technological and artistic, and we’ll be featuring several more over the course of the next week or so.

555 kit, version 2.0

555 Kit v 2.0

Today we’re introducing version 2.0 of our “Three Fives” Discrete 555 timer kit.  Version 2.0 has a number of little tweaks and improvements, with a cleaner design and — coolest of all — an all-new set of smooth anodized aluminum legs.

555 Kit v 2.0

The Three Fives kit is a faithful and functional transistor-scale replica of the famous 555 timer integrated circuit — one of the most popular and well-loved chips of all time. (An original NE555 IC is shown above for scale.)

We are also releasing the first version of our educational supplement for the Three Fives kit: A detailed description of how the 555 circuit actually works, with plenty of opportunities for further exploration.  You can find it on the downloads section of the product page or on our documentation wiki.

 

 

Stealth Fighter Guitar with Octolively Lighting Effects

Stealth plane guitar with octolively lighting

Herb wrote in to say:

When I saw your Octolively LED circuit, the first thing I wanted to do was incorporate it into our electric guitar project.

I teach a basic senior physics class for non-science majors and wanted to try something different; a year-long design project.

We made a guitar from scratch that resembles a stealth fighter. We even wound the humbucker coils in the guitar… Your circuit is used to drive the exhaust lights in response to playing motion…It works well and offers a unique visual effect based on the selected setting…you can even hear the circuit through the amplifier when it drives the blue LEDs…

The Octolively is wired up with the LEDs pointing down from the bottom of the guitar (back of the plane) and the sensors pointing toward the neck to respond the motion of the guitar player.

His student, David, added:

Thank you for making such a great educational product to learn about LED’s and simple circuits. Our class worked together to put all of the parts in the correct place and it was a wonderful collaborative learning project.
