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!

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.

LED Kitchen Timer

Dave wrote in to tell us about the kitchen timer he made:

I just wanted to say thank you for putting together such a great site and set of products. I’m a newbie and after about 4 months o studying your articles and using the Diavolino as my development board, was able to make a cool little kitchen timer for my parents this Christmas. I definitely could not have done it without your articles and products.

He documented the project with a series of videos (youtube playlist) showing his progression through building it. Shown above is the breadboarded prototype next to the finished timer.

Thanks for sharing your project photos and videos, Dave!

LED Pez Menorah 2013

Joyce sent us this picture of her 2013 Lord of the Rings Pez dispenser LED menorah.

I thought I’d share my new menorah hack with you all. Friends even started asking about “this year’s theme” so I guess it’s now an official tradition.

She incorporated our new multi-colored LED Menorah kit into this one. You can find our previous LED Pez dispenser menorah posts here and here.

LED Vertical Blinds


dinofizz posted in the forums about the LED display based on the Peggy 2 he installed on his vertical blinds:

I had custom PCBs made to help daisy chain the vertical blinds (they’re sitting on top of the horizontal beam from which the blinds hang). 300 ft spool of 16-way ribbon cable completely used up. Around ~4000 individual solder joints, and I’m still using breadboard to hold things together at the moment! Took me forever.

He linked to a few more build photos over in the forum post, and he even posted some video of it in action:

Surface Mount LEDs on a Through-hole PCB

Peggy 2le Surface Mount

Peter T. recently stopped by our shop with his Peggy 2LE and showed us his incredibly cool hack. He had noticed that the 0.1″ pin spacing for a standard through-hole LED is just about perfect to accommodate LEDs in a 1206 surface mount package.

Once he had finished populating all the LED locations, he brought it by again. He used an alignment jig he had made to keep everything in straight rows while soldering.

The surface mount LEDs look great on the grid designed for T-1 3/4!

We plugged it in so we could see his pretty orange LEDs in action. Thanks to Peter for bringing it by and letting us take pictures!
