Arduino-powered Etch-a-Sketch clock

Dodgey99 built an Arduino-powered Etch-a-Sketch clock, in which a pair of stepper motors painstakingly draw out the current time. It's got a very low refresh rate, though: the limits of the motors and the Etch-a-Sketch means that it takes more than a minute to display the time, and it needs a couple of minutes' rest between each number. There's a plan to accelerate things with some beefier motors.

I use an Arduino driving two very cheap darlington stepper drivers with 64:1 internally reduced steppers for the drawing. For the rotation I'm using an Easy-Driver driving a Nema 17 stepper.

I also have a DS1307RTC real time clock installed so it always knows the time. Setting the time is a one-off via USB connected to a PC. Once done, you un-tether, and then the RTC keeps the time, for up to a year on the rechargeable battery, or so I'm told...

The code is actually very simple, it's just a pain drawing the numbers!

The G clamp on the back is for a counter balance until I find something more elegant!

The steppers are far too slow to write the time in under a minute so I delay it for a couple of mins between each draw. Mostly to give the very hot motors a while to cool off and to give the etch a sketch a break!

Post-scarcity hacker convention: !!Con

Sumana is helping put on a new kind of hacker conference in NYC, !!Con (pronounced "Bang bang con"). Unlike other hacker cons, !!Con has no ranking, no winners, and no dominance displays: "Whenever possible, Hacker School culture assumes abundance rather than scarcity; attempts to rank projects or people would defile our ecology."

Bay Area drone-fliers' meetup

Jeffrey writes, "Bay area flyers, come talk and fly drones over pizza and beer in our massive 17 foot tall ceiling warehouse! Amateur and professionals are welcome to come and talk drones and show off their airframes in action. We'll have plenty of charging stations, onsite repair workbench, tasty local beer, and food/snacks for flyers. Compete for fun prizes, fame, and whimsical trophies in our drone flying contests. Starts at noon on April 5, contests start at 2 PM. Plenty of parking and free for all." Cory 3

HOWTO make your own head-in-a-jar illusion

By photoshopping a pair of mirror-flipped profile-shots of your face onto either side of a full-on shot, you can make a gimmicked photo that, when curled and placed in a jar of water, creates a convincing illusion of your head in a jar. Mikeasaurus's Instructable has easy-to-follow instructions for making your own.

Burned paper fingernails


Here's a great fashion idea for the next Banned Books Week: burned paper fingernails from Glitterfingersss. Basically, you soak newspaper in alcohol, transfer the ink to your nails atop a light nude polish, paint in the burned marks, and add a topcoat.

Resume in the form of a custom Lego figure


Leah is looking for a job at a creative agency, so she created a Lego figure of herself and boxed it up as a resume in the form of a custom kit. She made two of them, and used the instructions for building the fig as a means of highlighting her creative credentials. It's a pretty lovely piece of work -- I hope she gets a job!

Jimmy DiResta makes paper letters

It's no fun watching glue dry, unless it's part of a Jimmy DiResta how-to video!

I make a lot of signage, often using bandsaws and CNC machines. But not everyone has access to such tools, which can make creating 3D letters complicated. In this video, to demonstrate the use of paper and paper board to make letters, I create the “Make:” logo in chip board (orange) and a thinner paper (green) using only razors and Jade glue. It makes the process simpler to use a stronger board for the face of the letter, and the thinner paper to create the side of the letter. Enjoy!

Open source soft robotic quadruped with many applications

Pt and Limor write, "The Glaucus, named after the Blue Sea Slug (Glaucus Atlanticus), is an open source soft robotic quadruped from Super-Releaser. It is a proof of concept for a method developed at Super-Releaser that can reproduce nearly any geometry modeled on the computer as a seamless silicone skin. The company hopes to apply these same techniques to practical problems in medicine and engineering as the technology develops. The quadruped has hollow interior chambers that interdigitate with one another. When either of these chambers is pressurized it deforms and bends the structure of the robot. This bending produces the walking motion. It is similar to how a salamander walks, by balancing itself on one pair of legs diagonal from one another while moving the opposite pair forward."

Building Boing Boing's Happy Mutant Mobile

This post is brought to you by Ford.

Photo 1a

Above, our lovely mascot Jackhammer Jill in 3D-printed ABS glory! This 9" model of Jill will get hand-painted and rigged with advanced bubble-blowing technology before being mounted in a place of honor on the hood of our Happy Mutant Mobile! As we've posted, our sponsors at Ford agreed to support the customization, modification, and transformation of a 2014 Ford Transit Connect Wagon into what we (and you) imagine for a Boing Boing vehicle. (Original announcement here and check out all the posts here!)

Theresa Contreras and her talented team of makers at L&G Enterprises in San Dimas, California are tirelessly tricking out the vehicle with a cabinet of curiosities behind the rear door, 'zine/comix library behind the side door, projection screen for viewing psychotronic films, a mobile video blogging studio, and numerous amenities like a 3D printer and cold drip coffee maker. Oh, and just wait until you see the mindbending exterior artwork from our hyper-talented friends at We Buy Your Kids. Below, rough blueprints and in-progress shots of the woodwork and the interior.

Desklamp comes alive with Arduino

Add a few servomotors and an Arduino to a desklamp to make an appliance that seems to be alive.

Pinokio is an exploration into the expressive and behavioural potentials of robotic computing. Customized computer code and electronic circuit design imbues Pinokio with the ability to be aware of its environment, especially people, and to expresses a dynamic range of behaviour. As it negotiates its world, we the human audience can see that Lamp shares many traits possessed by animals, generating a range of emotional sympathies. In the end we may ask: Is Pinokio only a lamp? – a useful machine? Perhaps we should put the book aside and meet a new friend.

HOWTO make your own chocolate chip cookie milk-cups

On Instructables, Klee67 has remade the chocolate chip cookie shot glass recipe in a home version that anyone can bake. Her tutorial starts with a modified version of the Serious Eats "Best Chocolate Chip Cookie" (increasing the flour and beating more), baked in a popover pan with molds made from corks, foil, paper towel rolls and baking parchment. She's still looking for a viable glaze to keep the seepage to a minimum. Do you have any ideas?

Here's a review of the Mark II cookie-cups that cronut inventor Dominique Ansel sells at his NYC bakery.
