Maker Faire Detroit Pictures and Highlights

Maker Faire Detroit

Maker Faire Detroit was a blast! It was held at The Henry Ford, which is a museum worth visiting in its own right. It is an amazing place we didn’t get to see nearly enough of and would love to go back and visit again.

In addition to providing a history of American manufacturing and a showcase of amazing vehicles, they have Mold-A-Rama machines!

As usual, one of the most exciting things about Maker Faire for us was meeting and talking with other makers. We got to talk to the participants in an aluminum casting demonstration, who were using foam that was carved onsite with a CNC router.

We also really enjoyed our neighbors at the faire with the Note Grinder, a machine that read player piano rolls optically and used door lock actuators to press the keys on a synth keyboard. We were impressed with how pleasant it was to listen to (even for two days straight!) especially with the rhythm accompaniment provided by the actuator motors.

The fine folks at Context Furniture were passionate about the renaissance of craftsmanship in Detroit and had great stories of reclaimed buildings.

We were tickled to see several Evil Mad Science kits integrated into Maker Faire projects: a Peggy 2 being used as a readerboard, Wes and Don‘s 3D POV display with a Peggy 2LE, and Matt Mets’ Meggy Jr Sr.

Our Eggbots performed like champs, and we even tried out engraving on glass holiday ornaments during the faire. The engraver scratched away the paint on the surface, and as you can see in the top picture, they were beautiful when lit from within by an LED.

We didn’t come close to seeing everything, but we’ve put pictures of some of what we saw in a set on flickr.

We hope to see you at Maker Faire New York!

More cool electronics tools

Cable tie tool 1

What is it? Hint: your life depends on tools like these.

Some time ago we wrote about five relatively obscuretools for doing electronics. But, five tools barely scratches the surface of the stuff out there, and here are a few more of our favorites. In this roundup we’ve collected some handy–and even important –tools along that you might not have seen before, along with some best-of-breed versions of everyday electronics tools.

Diavolino

Diavolino-angle2

Say hell-o to Diavolino. Yes, it’s yet-another Arduino compatible board, but it’s cheap and kind of neat. Simplified design, rounded corners, and shiny. Open source kit. You can get one at our store here.

We designed this primarily in response to local need in our San Francisco hacker community for low-cost boards for teaching.

In many ways, this project is reminiscent of and complimentary to our ATmegaXX8 target boards, which are low-cost, simple design circuit boards for programming AVR microcontrollers through an ISP connection. And while you can add one, those boards don’t have a place to put a USB-TTL cable. And so here we are. Continue reading Diavolino

Tricks of the trade: Twisting wire bundles

Wire Twisting - 23

A common problem that you may come across when building “a box” to do something– whether a one-off gizmo or bona fide scientific instrument –is the rats nest of wires. A similar problem occurs when you need to run a bunch of basic wires out from your box to other devices. Unless there’s a standard cable lying around that does exactly what you need, you can end up with messy tangles of wires outside of your box as well.

There are many well-known solutions of course, as varied as elegantly laced wiring harnesses, cable tiesand teflon spaghetti sleeving, heat shrink tubing and cold shrink tape, and (possibly for the brave and/or insane) duct tape and paperclips.

Wire Twisting - 25

One of the other basic methods– well known to many people who build electronics –is to twist wire bundles with a hand drill and a friend. This is a quick and awesome trick that makes durable cables, short or long, exactly to your specifications, and shockingly fast.

DIY Fever: Heading to Maker Faire

It’s a busy week at the labs here. We’re getting ready for Maker Faire this weekend in San Mateo, CA– the biggest, baddest, and most awesomest DIY festival of the year.

We’ll be showcasing an updated version of our mechanical Pong game. We’ve added a curved playing field, new user-friendly knobs, and a host of other improvements that we’ll plan to write about at a later date. We hope you’ll come by and try it out–we’ll be on the west side of the Expo hall.

Tabletop Pong - 92
Some of the other projects that we’ve taken to Maker Faire in the last few years include our Interactive LED Dining Table, CandyFab, Bristlebots, Interactive LED Coffee Table, Peggy 2, and Meggy Jr RGB.

We’re also participating in the Open Source Hardware Panel, on Saturday at 1 pm at the Innovation Stage at the south end of the Expo Hall.

We’ll have much more to say about this later, but we’re thrilled to announce our new collaboration with Bruce Shapiro, Ben Trombley, and Brian Schmalz. While we’re demonstrating the Tabletop-Pong game, Bruce and friends will be giving a sneak peek at the results of our collaboration: a fantastic new version of the Eggbot kit, which we are preparing for release as an open source kit sometime this summer.

Eggbot kit - preview 2

You can sign up here for more info about the kit, and you can try out the Eggbots– or just see them in action –in the center of the Expo Hall.

Lastly, to help get everyone else in the DIY mood, we’re having a DIY Fever sale over at the store, with 20% off of Evil Mad Science open-source kit favorites such as the Larson Scanner, Meggy Jr RGB and the Bulbdial Clock, and 10% off of everything else!

Happy hacking, and we’ll hope to see you all at the Faire!

Upcoming events: RoboGames and Maker Faire

Hey Guys!

Neat-o stuff to do in the San Francisco bay area:

Next weekend, go to RoboGames, Fri-Sun, Apr 23-25, 2010 at the San Mateo Fairgrounds. It’s the worlds largest robot competition, featuring combat robots, humanoid robots, art bots, soccer bots, sumo bots, and more. We’ll be there as exhibitors, with kits from our web store and other goodies like pager motors for making BristleBots!


In May, we’ll be heading back to the San Mateo Fairgrounds for the Bay Area Maker Faire 2010— our favorite event of the year. It’s the world’s biggest DIY festival, and well, there’s just too much to describe. You have to see it for yourself. We’ll be there showing off one of this year’s Evil Mad Scientist Laboratories blog projects, the Playable game of Tabletop Pong— you can come by and try it out.

Hope to see you there!
