Maker Faire Austin Pictures

lovely sign for the show barn

We had a wonderful time at Maker Faire Austin. I’ve put some pictures and videos up in this flickr set for your enjoyment.

Electrified Monopoly   Maker Faire Austin

Our neighbors at Maker Faire were Kris and Carly who were doing very fun things with LEDs, like making Monopoly more fun by lighting up when you land on certain squares. The no-solder wiring system was very clever, and the flashing blue and red lights in jail were perfect.

Maker Faire Austin   It's the gnomes that make it perfect

This cute little robotics platform stopped by for a visit, but in order to see most of the rest of the faire we had to pry ourselves away from our table, which was tough. There was a nice collection of art cars, including this Chia Car. Maker Faire is wonderfully overwhelming, and we didn’t take very many pictures. Luckily, many other people took pictures too, and you can check lots of them out on flickr.

 

Reminder: Microcontroller classes this week at TechShop

   ATtiny2313

Tomorrow (Monday 3/3/08) at TechShop in Menlo Park, CA, I’m giving another AVR intro class. These classes have been big, lively, engaging and interesting, with a lot of good questions– two sessions are scheduled this month:

Monday, 3/3/08, 6:30-8:30 PM, and

Saturday, 3/22/08, 1:00-3:00 PM

Seminar: Introduction to AVR Microcontrollers

AVR microcontrollers are powerful and versatile single-chip computers that cost only a few dollars each. You may have noticed that a number of our interesting projects are based around these, using them to make smart little toys and machines.

This class is aptly billed by TechShop as “How To Use AVR Microcontrollers in Your Projects.” Indeed. We’ll be bringing along a number of our cool AVR-based Evil Mad Scientist Laboratories projects from to show off some of the things that you can do with these little marvels, and how you might go about doing it.

Formal class description: “AVR microcontrollers are powerful, versatile and inexpensive single-chip computers that are remarkably easy to program in C, using entirely free and open-source tools that run on Macs, Windows, and Unix-like operating systems. In this practical introduction to AVR microcontrollers, we’ll take it from the beginning so that you can get started using them for your own cool projects. Some topics to be covered include: different types of AVRs and how to pick one for your application, getting a programmer, installing software tools, how to get started actually programming them, and how to download and run your code on the microcontroller. Class format is a one hour lecture followed by show-and-tell demonstrations and ample time for questions.”

Seats are still available in one other microcontroller project class:

Soldering Project: Build a Micro Readerboard

A fun little soldering class, where you can customize the phrases in and build your very own LED Micro-Readerboard. It’s a cute little toy that spells out a preprogrammed messages (e.g., your name– for an LED nametag!), one letter at a time, on its display. In the class, you get to choose what messages to put on your readerboard, solder it together and take it home. It’s a neat, self-contained project that’s a great example of what you can do with a little AVR microcontroller; a perfect “my first microcontroller” project for anyone who hasn’t played with one yet. This is an intermediate soldering class; some prior soldering experience is needed. Other than that, no prior knowledge is assumed, so this class is great for kids too.

Next Classes:

  • Saturday, 3/8/08, 1:00 PM
  • Saturday, 3/22/08, 4:00 PM

Weekend Projects with Bre Pettis: Make a Joule Thief

Weekend Projects Podcast!
In this week’s Weekend Projects video podcast, Make Magazine’s Bre Pettis and I show you how to make a Joule Thief. The PDF file that goes with the podcast is here (450 kB PDF file).

So whatsa Joule Thief? It’s a little wisp of a circuit that allows you to drive a blue or white LED from a low voltage. Normally, if you want to light up a blue or white LED you need to provide it with 3 – 3.5 V, like from a 3 V lithium coin cell. But a 1.5 V battery like a AA cell simply will not work. But using the Joule Thief, it works like a charm. Not only does it work with a brand new battery, but it works until the battery is nearly dead– down to 0.3 V. That’s well below the point where your other toys will tell you the battery is dead, so it can steal every last joule of energy from the battery (hence the name). To learn how to make one, watch the video, which is available in a variety of formats.

The original site where we learned about the Joule thief shows you how to make a miniature version of this circuit, such that you can fit it in a tiny flashlight. However, in the video we show you how to make it big, large enough (1) to make with clumsy hands and (2) that you can see what we’re doing.

After the jump, some detailed photos of how the coil is wound in case you need more detail than in the video.

CandyFab @ Dorkbot: 8/15/07 @ TechShop

symmetric view 2

On Wednesday, August 15 we’ll be giving a presentation about CandyFab at a meeting of Dorkbot SF, our local spinoff of
Dorkbot NYC.

Dorkbot chapters organize monthly talks and events for artists, scientists, and engineers centered around the theme of “the creative use of electricity.”

The meeting will be held at 7:30 PM at TechShop, a San Francisco Bay Area “open-access public workshop,” located just off of 101 in Menlo Park, where you can go use a wide range of tools and machines to make things. We’ll be bringing the CandyFab machine along, and– if everything goes right– demonstrating its use. So if you’re in the SF bay area, this is a great chance to come and take a close look at the CandyFab 4000, smell the caramel, and ask questions. Besides our talk and demo, there will be a couple of shorter presentations on other dorkbot-ish topics, and an introduction to TechShop. (Tours of Techshop will be available at the end of the meeting as well.)

Everyone is welcome to come to the meeting; there is a $5 suggested donation for the venue at the door.

UPDATE: The event was great! (Read more here.)

Circuitry Snacks

555 LED flasher 1

PCB with components   Joule thief 2

Here we present what is arguably the tastiest way to design and learn about electronic circuits: make circuitry snacks!

Two of our favorite things in the world are playing with electronics and playing with food, and so it is about time that someone finally got around to combining the two. We begin by gathering up appropriate snack-food building blocks and making food-based models of electronic components. From these components, you can assemble “circuitry snacks”– edible models of functioning electronic circuits. You can make these for fun, for dessert, for your geek friends, for kids, and for teaching and learning electronics.

Class Reminder: Choosing a Microcontroller (Sat 7/7 @ TechShop)

ATtiny2313MakeController

Tomorrow I’ll be again giving my seminar called “Choosing a Microcontroller” at TechShop. This class is a broad introduction to the capabilities and variety of single-chip computers, as well how to actually pick one for a given application. It’s easy to get overwhelmed looking at the variety of range of micros, from four-bit micros that have a 4-bit wide data path — and actually cost four bits— to AVRs and PICs, basic stamps and Arduinos, to 32-bit gorillas with names like ARM, Blackfin, and Coldfire. So, we’ll try and cut through the fog and help you figure out where to get started.

If you’ve heard people getting excited about or doing cool things with microcontrollers and want to learn more, this might be a great introduction to the field.

Sign up for the class here.

If you are interested in the topic but can’t make it, you might want to take a look at our
list of resources for choosing microcontrollers.

This is the last time that this particular class will be offered in the near future. Another intro AVR class will be forthcoming, probably in August. As always, if you have other ideas for classes that are within our expertise, please let us know.

Reminder: Upcoming classes at TechShop

led micro-readerboard   Blinkylights1

Build your own LED Micro-Readerboard this Satuday (6/30, 1:00 PM) at TechShop. It’s a single class where you choose phrases for and solder together your own LED Micro-Readerboard. As a new option: you can choose to make yours an AlphaPOV display! This class is a fun first introduction to what you can do with a microcontroller– where you make a neat toy that you get to take home. (Kids can take this class too, assuming that you’ve already taught them to solder.) Sign up here.

A week later, “Choosing a Microcontroller” (7/7 @ 1:00 PM) is a detailed seminar on the capabilities of microcontrollers and walks you through the process of finding one for your application. Sign up here.

Make a custom LED Micro-Readerboard

Next Saturday, June 9, I’ll be giving a fun little class, suitable for anyone with a bit of soldering experience (even youngsters), where you can customize the phrases in and assemble an LED Micro-Readerboard. It’s a cute little thing that spells out a preprogrammed messages (e.g., your name), one letter at a time, on a single-character alphanumeric display. These are much like the ones that we programmed to be holiday ornaments a few months ago, but these are actually extra-spiffy version 2.0 micro-readerboards with higher brightness and better battery life. And, if you take the class, you get to choose what messages to put on your readerboard and take it home. It’s a neat, self-contained project that’s a great example of what you can do with a little AVR microcontroller.

(UPDATE: Second class added on June 30, also at 1:00 PM.)

Introduction to AVR Microcontrollers

Saturday, June 16, 1:00 PM

You may have noticed that a number of our interesting projects are based around AVR microcontrollers. AVR microcontrollers are powerful and inexpensive single-chip computers that are available in a wide range of sizes. They also happen to be remarkably easy to program in C, using entirely free and open-source tools that run on Macs, Windows, and Unix-like operating systems. In this practical introduction to AVR microcontrollers, we’ll take it from the beginning so that you can go home and use AVRs for your own cool projects. Some topics to be covered include: different types of AVRs and how to pick one, what kinds of programmer you should get, how to install the software tools, how to get started actually programming them, and how to download and run your code on the microcontroller.

Choosing a microcontroller

Finally, on July 7, I’ll be giving a repeat of this introductory microcontroller class, called Choosing a Microcontroller. This large-format seminar is designed to be a broad introduction to the capabilities and variety of single-chip computers, as well how to actually pick one for a given application. It’s easy to get overwhelmed looking at the variety of range of micros, from four-bit micros that have a 4-bit wide data path — and actually cost four bits— to AVRs and PICs, basic stamps and Arduinos, to 32-bit gorillas with names like ARM, Blackfin, and Coldfire. So, we’ll try and cut through the fog and help you figure out where to get started.

(By the way, it’s hard to tell what types of things people want to learn about. So, if you have suggestions for other classes that you’d like to see taught by the Evil Mad Scientists, you can E-mail us or leave comments here or in the forums.)

Maker Faire Bay Area 2007 was fantastic!

Kill your television and make stuff!Maker Faire was a smashing success. The big message of the fair was summarized succinctly and stamped on the back of a card we were given: “Kill Your Television and Make Stuff!”

We had a great time in our little prototyping world off in the corner of the Expo hall by SRL. Near us Bathsheba Grossman had her beautiful sculptures, Fab@Home was printing with cheese and frosting, John Guy had his 3D CNC gantry next to his margarita machine, and Lee Krasnow had an entire workshop for his precision puzzle making. We were also by a couple of exhibitors (as opposed to makers): Epilog and Protopulsion, but I have to say, it seemed like the makers all got a lot more traffic than the corporate folks with their tradeshow-style setups. We were all off behind the Tesla coils, which stole our visitors’ attention hourly. Nobody could compete with the Tesla coils when they were running!

We can’t possibly list all of the cool things we saw, and we didn’t see half of the stuff there, but read on for some of the highlights for us.
