Arduino Powered Handheld Wall Printer

Print a programmable message on any wall.

Felix Vorreiter from Germay made the txtBOMBER, a Arduino-powered hand held device that controls seven markers to print a programmed message on any wall or other flat surface. The markers move up and down, drawing dashes that combine to form the letters. In his portfolio he says that it is intended to print political statements as part of a guerrilla art campaign.

We posted a printer made from LEGOs a little while back with a similar technical system but intended for desktop use.

Digi-Fabrics

3d Printed Fabrics – Super Strong and Flexible

There have been some interesting explorations happening over at Shapeways. Just in time for SIGGRAPH 2010, these 3d printed digi-fabrics are most probably unlike anything you’ve ever seen before.

Except maybe rubber. Apparently they behave just like a rubbery fabric – with strength under compression and a degree of flexibility when tension is applied. But they came out of a 3d printer! Amazing.

Check out the following video… I can’t wait to see how far people take this! Fancy-dress parties will never be the same again.

We found a few gems at SIGGRAPH last year; stay tuned for more goodies from the 2010 event.

Free Course on Processing and Arduino

No previous experience is needed for this free five-week online course.

Processing and Arduino come up pretty regularly on this blog. We can’t help it; there are just too many incredible things being done with them. Just look at this chair-generating software or this amazingly elaborate laser engraved artwork. These are two totally different projects, both accomplished with Processing. What Processing does with software, Arduino does with hardware, and the best thing is that they can be used together, like for these butterflies.

If these great projects have piqued your interest, read about a chance to try out Processing and Arduino for yourself after the jump.

Algebra Tiles & Robotic Brushes

recent Instructables from frenzy

Instructables intern and computer science major under the nickname frenzy recently posted a couple of projects — one tackling the teaching of algebra and another tackling a city sidewalk.

Algebra Tiles uses lasercut acrylic pieces to visually demonstrate perfect square trinomials. It’s an interesting to way to approach algebra in a more geometrically representative way.

If you’re one of those kids that naively complained “I want to learn something that’s going to help me in real life”, there’s a new Instructables for you, too.

Giant BristleBot is like a robotic broom made with “fast spinning objects and high torque motors.” The designer calls his robot a “death bringer” but it reminds me a lot of that scene in Sword in the Stone where Merlin cleans up a big mess with magic.

Laser Party

Well THAT was awesome!

Billed as a party from the future, the recent Laser Party hosted by Design Glut and NY Designs saw all manner of fun and games emerge from one action packed evening.

People were invited to submit ideas for laser cutting and laser etching to be produced for free as a part of the event.

The outcomes give a taste of the creativity and fun that ensued; and I mean that quite literally –  click through to see the laser cut ham sandwiches…

Make Prototypes for Laser Cutting at Home

Quickly and easily make paper prototypes with a CNC paper cutter.

Everyone who uses laser cutting for projects eventually encounters the same problem. You carefully double check your files, making sure that all the measurements are just right, send them to the cutter, get back the cut pieces, assemble the project . . . oops. Something isn’t right. Now you have to fix the files, send them back to the cutter, and wait.

Making prototypes can drastically reduce how often this sort of thing happens. For simple projects cutting out paper or cardboard with an X-ACTO works just fine, but this can be aggravating for more complicated project.

I came across a handy little device for automatically making paper prototypes while researching the Sketch Chair post. Unlike a laser cutter, these home-grade CNC paper cutters are affordable for someone in a home workshop with prices from only $250 up to around $1200. They use digital vector files like a laser cutter, but instead of a laser they use a small blade to cut the material. While they only cut materials like paper, card stock, or vinyl, they would still vastly simplify the process of making prototypes and models.

Read an overview of different types of CNC paper cutters after the jump.

Don’t Eat the Sprouts

Home-goods from New Yorker Pepper Sprout Designs

Current incarnation of Pepper Sprout Designs started with the discovery of Ponoko who, at the time, were sponsoring a contest with CRAFT magazine and Etsy.  It may have been some sort of Halloween contest and there was a small discount to try out their services.

How did you used to make products before Ponoko?

The things I made before Ponoko are actually completely different in terms of materials and ideas. I was actually selling a little bit on Etsy with some soft stuffed creatures, and prints. Needless to say I wouldn’t have my current product line without Ponoko.

What type of products do you make with Ponoko?

Right now I am currently making home-goods and personal accessories. My biggest sellers are my coasters, but I have also expanded into a few pendant designs, felt trivets… and a few new ideas that will be coming soon. (Let’s just say it involves cheese)

How would you describe your creative process?

Ideas seriously just pop into my head. I’ll either be driving around, or in a shop, or watching tv and I’ll have to grab a notepad and jot down an idea before I forget. I have a terrible short-term memory. I normally sketch out a rough idea and then go straight into the computer to draw everything out and make sure it’s going to be a viable product to produce. Occasionally I come up with something that is just too complex to be worth it financially, but most of the time we can make it work.

What material/s do you use/ have you used and why?

I’ve used acrylic, bamboo, cherry and walnut veneers, felt and even the stainless steel. Each material offers something a little different. I think it’s been really fun to experiment with them all and find the places they work and don’t work. Knowing the limitations of the materials allows me to know which will work best for a new idea, and having a rough idea of cut time and material price helps as well.

Have you been surprised by anything in the Ponoko process: positives/negatives?

I was actually surprised at the detail you can get. I mean I have seen things lasercut before but it was so cool to see the detail you can get. I recently did a mini version of my holiday snowflakes (they are normally about 3″ and i scaled them down to about an inch) they look amazing and they aren’t as fragile as I thought they might be. I also have been blown away with the customer service Ponoko provides. Everyone is super nice and happy to walk you through something if it isn’t quite making sense.

Do you have any tips for other users?

I’ve become kind of a fly-by-the-seat-of-my-pants Ponoko user. After i tested a few things on p1’s I actually stopped doing small test runs and just been going for it on a p3 right out of the gate. So far everything has worked great. But my tips would be….

Print your design on paper before you order, you might see something you didn’t before, or the size could be off. Also zoom in when you are creating, every once in a while you might find a line that doesn’t connect but needs to. Connect as many peaches as possible to keep your cutting time down. Sign up for PRIME, it has been so worth it!

Sourcing Hardwoods for Your Digital Making Projects

Material Monday: Possible wood suppliers for Ponoko Prime material requests.

As most of you know, Ponoko Prime members can make material requests — as long as the materials meet certain size requirements,  there’s no minimum order, and can be shipped to a Ponoko making hub.

Ponoko user O. Gunther recently asked if anyone knew where he could find wood materials that would meet Ponoko’s requirements. After a bit of research, I’ve come across a few possibilites. (But note that I have not confirmed any of them.)

First of all, the size requirements are:
• thickness must be 3/8″ or less
• sheets must be available in 7.5″ x 7.5″ / 15.5″ x 15.5″ / 15.5″ x 30.5″

One possibility is Birchwood Best, a Wisconsin based company that offers cut-to-size hardwood plywoods. They also make it a point to serve any customer, “Whether you are a large manufacturer or a small cabinet shop, we want to be able to help you.” And they offer every commercially available species of wood. You can contact Birchwood Best HERE.

Another possibility is Premium Wood Products. They do custom wood cabinetry out of Illinois. Their site doesn’t overtly claim to do cut-to-size wood sheeting, but they do claim to be a “quality source for precision wood parts…” You can contact Premium Wood Products HERE.

For those using the Ponoko NZ hub, Mister Ply&Wood could be a possibility. This Australian based company offers a cut-to-size service for any size job and variety of MDF veneers all available in a thickness of 4mm. They also have a variety of stores around Sydney, so you could take a look at the material before requesting it. Contact Mister Ply&Wood HERE.

If anyone else has a suggestion for sourcing hardwoods, please leave a comment.

Own your own laser-cutter? Two material leads for ya, after the jump.
