LED Robot Sign

Krummrey shared an LED Robot Sign tutorial on Instructables using one of our original Peggy boards. (Peggy 2 would work for this, too.)

I don’t solder the LEDs in. That way I can just pull them back out and make a new sign when I get tired of the current one.

That big pile of LEDs looks like so much fun! He also posted some more sign designs at the end of the instructable.

Electro-Kistka: Alternate In-Place Egg Dyeing Technique

After seeing our recent post on dyeing in eggs in place with the Eggbot, Ragnar posted instructions in the forums for an alternative egg dyeing technique.

It involves pre-installing a plastic dyeing bag at the time of positioning the egg in the Eggbot. Full instructions (with more photos) are in the forum post. Thank you for demonstrating this technique, Ragnar!

Electro-Kistka: Dyeing an Egg in Place?

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!

Highlights of the 2014 Bay Area Maker Faire

BAMF 2014 77

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.

A WaterColorBot Water Clock

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:

Maker Faire Bingo

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.
