One type of mechanism that you might consider is a solid state relay, one is rated to handle 12 V DC at sufficient current as your motor draws. The input to control the solid state relay is usually (essentially) an LED, so if you can control the…
-
First off, as you know, setting a limit higher than 30 mA is not "officially supported," but we'll do our best to help you out. For maximum current, solder together the two connected (or all three) pins of VR1 and VR2. Then, put the selected resis…

>Funny enough, the onboard Pi computer, at $35, is even less expensive than the EiBot motor controller board. It never fails to amaze me how stark the differences are between the costs of things when you're making hundreds (or even thousands) at …

The instructions are in Part III of our essential documentation, the part about Making Your First Plot: http://wiki.evilmadscientist.com/Making_your_first_plot#Drawing_on_your_Egg

It's very neat that you can run Inkscape on the Pi, and I've added a link to your Instructable to our wiki. However, the Pi is indeed an external computer-- a full featured, tiny and cheap computer-- that communicates to the EBB through USB. It is…

The shaft collar (the metal piece) is glued into the wooden part with superglue, and needs to not slip. You can either get some super glue and add repair it yourself, or write to our shop using the contact form ( http://shop.evilmadscientist.com/co…

Wow-- great! That's a pretty strange bug, indeed....
-
The distribution includes the source code, and the image along with it. I would have guessed that the executable includes the actual "grace.jpg" image internally, and doesn't look at the version from the source code, but from the sizes of the files…
-
Hmm. Unfortunately, I don't immediately know how to fix that. Do I understand correctly that it still runs correctly on the "Grace" image?
-
The change on your computer could have been the Java version...?
-
Which version of processing are you using? I wonder if you need to downgrade....
-
Hmmm. That's very strange, and I'm not sure what the problem could be. You might try resizing your initial image to be smaller in number of pixels. The image window is only 800 x 600, so if you start with an image that size, you should reduce the…

Hi earvedson, There are two likely possibilities. Either the servo is not configured correctly, or your servo is bad and needs to be replaced. First, double check that the servo is plugged into the EBB correctly. Next, remove the servo from th…
-
Hmmm. Good suggestion!
-
Great-- glad to hear it!
-
You need to connect pin 20 to V+.
-
Also, double check that you have +V at pins 20 and 21.
-
What is your power supply voltage? And, are you sure that there's a good ground connection between the paddles and the AVR? If no buttons are pressed, what happens?
-
Do you have the 10k pull-up resistor in place? And, are you sure that your buttons are "normally-open" types? Check to be sure that the button input pins on the AVR show 5V until hou press the button.
-
This may have to do with the "paddle" inputs. If they are at the edge of the range, IIRC, they can serve backwards.
-
Hmmm-- this is getting interesting! The response that you got (Serial(port='/dev/ttyACM0', baudrate=9600, bytesize=8, parity='N', stopbits=1, timeout=None, xonxoff=False, rtscts=False, dsrdtr=False)) indicates that python *is* able to open the ser…

Hi Ugi,Yep, that's pretty neat. We've been working on our own "cylinder" adapter for some time, but the thought of making it large enough to work on coffee mugs is not bad at all.
-
Here are two more things to check: 1. At the terminal, please list the output of: ls -l /dev/ttyACM* -- just in case there is some other permissions error on your system. 2. Check to see if python can connect to the EBB directly: At the t…

Hi Ron,Our goal is that you can use the Eggbot on any of those systems. And, thank you for your kind words about the kit-- that really makes our day. I've tracked down the problem, which turns out to be that there are new permissions required to a…
-
OK, great thanks-- looks like your computer can see the EBB, but not communicate with it. (Edit: Obviously you were seeing it in a different way earlier-- the ACM* ports are how we try to address it.) And, checking here-- yikes-- we have the same s…

>Lbuntu "/dev/serial/by-id# ls usb-SchmalzHaus_EiBotBoard-if00" I'm not sure that I follow. First, is "Lbuntu" the same as Lubuntu, or is this a different distribution? Second, please try the following command, and let me know what output you ge…
-
First, which Linux distribution/version are you using? We developed the Eggbot under Ubuntu, and we've had scattered reports of success with other distributions as well. (And, one person reported having trouble with Gentoo last year, but we've bee…

Good news/bad news: It looks like this is a known bug in Inkscape, with a fix committed. However, the fix is committed for version 0.49, which is not yet released. Darn. https://bugs.launchpad.net/inkscape/+bug/166302
-
On second thought, looking at your picture, it looks like something has gone wrong here. The right portion of the uppermost straight line has disappeared, and it seems to do this on my computer as well. Yikes.
-
I've just tested this again, with the same example, and it seems to work fine. You do still have to click on each of those horizontal line segments, and delete them individually. If it's not working, perhaps the paths were not combined successfully.…
