In our annoucement article about the EggBot Electro-Kistka — the hot wax dispenser for the EggBot — we noted that it can be challenging to reposition an egg after taking it out to dye the egg between wax layers.
As an alternative suggestion, reader Dan commented:
Could you leave the egg in the EggBot and paint on the first layer(s) of dye with a brush? Then dip the egg for the last layer to get the ends covered.
Well, let’s try and see how it turns out!
We just stumbled across a post from last year by WidgetNinja about using our post about CNC halftones to make Tie Fighter ASCII art using his CNC router. He used two-tone plastic mounted on plywood and carved it with a 60 degree v-carving bit. It looks great!
“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!
Jens added a new tool option to his DIY Laser: a pen holder.
Due to safety concerns I couldn’t run the laser out in public, but to be able to show of the CNC capabilities I built a penholder.
The pen holder design was inspired by the WaterColorBot’s brush holder, with its parallel flexure hinges.
My Classic Lego Space flight jacket project appears starting on page 70 of the current issue of Make: Magazine, Volume 39. You can find the complete instructions on our blog, here.
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.

We built a evaporating-hand water clock using a WaterColorBot fitted with a Buddha Board. The Buddha Board is a black board with a gray ceramic coating that becomes transparent when wet, so you can paint on it with plain water to make black marks that disappear as the water evaporates. (And, it fits nicely in a WaterColorBot with the appropriate jig.)
As a clock, once a minute it draws the minute hand, then the hour hand, and finally the outline of the clock face.
As the water evaporates over the course of a few minutes, the old minute hands fade away. It’s a neat effect.
And of course, video:
With Maker Faire coming up next week, @techninja42 suggested that Maker Faire Bingo would be a great way to get ready! With the help of some friends, he put together a site where you can grab a bingo card to play during your visit to Maker Faire. We tried it out with the WaterColorBot, but you can use your preferred automated printing method to make your own, or maybe even find a robot at Maker Faire to draw it for the ultimate Maker Faire Bingo!
Send your maker bingo suggestions to @mfbingo for inclusion in the bingo card generator.

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.
Jens demonstrates using StippleGen2 with his low-power (300 mW!) DIY laser cutter and a classic image of Louis Armstrong.
After letting StippleGen2 crunch the numbers for a while I imported the resulting vector graphic file into inkscape and generated the G-code so that I could use my laser cutter to cut the image into a black paper. 2 hours and 23 minutes later I had a 20×20 cm piece of paper with about a 1000 holes in it and it looks awesome! Would be perfect for a lamp shade or just nice to put up in a window and let the sun shine through. I can highly recommend StippleGen2 it’s super easy and a lot of fun.
