The wiki does specify Arduino 1.0.3 as the required software, so that's only *almost* following wiki procedures. In any case, I've downloaded 1.0.5, and I am unable to reproduce your error (at least on a Mac). The error may have to do with the und…

I guess I'm not familiar with a "TTL level COM" port, but if it exists, then there should be some way to hook it up. The FTDI adapter is not strictly necessary, and there are a great many articles out there about programming an Arduino directly fro…

Hi Nadine,Interesting! One (longshot) thing that you might try is saving the file in the format "Inkscape SVG" and re-opening it, to see if that helps to fix any bad paths. Is there any chance you might be willing to post a link to the file so that…
-
Fantastic-- glad to hear it! (But, I wonder what kind of inputs can cause the program to fail like that?)
-
The current range is roughly up to 25 mA per LED, in the time that they are lit, so it should not be possible to damage the LEDs through code alone. That was a tricky design decision; it could be much brighter if it weren't so important to keep it …

Our technique is much like mlowe's, except that we just sight over the edge of the ornament to the edge of the Eggbot's frame. With motors off and pen up, I spin the ornament around one full turn by hand, and align it such that the highest point is…

In our experience what happens when you wash a board with alcohol is that it partly dissolves the remaining solder flux, and spreads it around in a thin, sticky, sometimes white and flaky, but all-around awful layer that remains when the alcohol eva…
-
For the record, we did update the extensions with the change suggested by jlauro, which was necessary to fix a change in Inkscape as of 0.48.4. This fix is included with extensions version 2.3.4 and higher.
-
What kinds of objects are you printing on? And, are you printing one-after-another of the same type of thing, or always changing between different types of things?
-
Hi Jim,I'm sorry to hear about the trouble. If the power is good, then you're right that the chips should be the next suspect. I'm not sure what could have happened-- could be power surge related, for example. The one other thing that you might …
-
Also, check the orientation of the phototransistors and the two diodes. Any of those backwards would cause this condition.
-
Running the LED display takes a certain amount of CPU time, as would running spectrum analyzer code, so while I am certain that it can be done, I am not certain *how fast* it would be. You might begin by looking at the Peggy2 library for Arduino an…
-
Essentially, you need to duplicate the functionality of the program to send the data to one Peggy to send it to the other as well. It may be easiest to generate two separate 25x25 arrays in the Processing sketch, and duplicate the existing code tha…

While there is an SPI hardware interface available, there is no software presently implemented to receive commands or codes over SPI-- the code would have to be written to do that.
-
Yes, the SPI interface is available. Also, the Octolively already has 8 sensors onboard-- to operate those IR sensors --and 5 additional digital I/O lines normally connected to the neighbors. That's up to 13 lines, 8 analog/digital, 5 digital. …

LED D2 is controlled by pin PD6/OC2B. LED D1 is controlled by pin PD7/OC2A. The definitions and functions of TCCR2A and TCCR2B are given in the ATmega644's datasheet. The default code to configure those two registers is as folows: TCCR2A = (_B…
-
They're custom machined out of Delrin. They slide directly on the wood, and the friction is generally negligible compared to the rest of the system. We verify this by turning it upside down, and seeing that it doesn't change much. There are some …
-
That definitely sounds like a problem with one channel of the EBB. Please contact our store directly about getting a replacement: http://shop.evilmadscientist.com/contact
-
I would second that!
-
The current design of the WaterColorBot frame does not permit vertical operation. The rods glide on sliders that are held down to the frame by gravity. It would be possible to design new rod-end sliders that would constrain the rods vertically, in…
-
I'm sorry to hear that you're still having trouble with it. However, it is likely that the kits are both recoverable, should you decide to look into it again.
-
Hi Glenn,You do not have to program the microcontroller at all-- it comes preprogrammed, and it *is* working correctly if you see one of the LEDs lighting up now and then. (If you do have a reason to reprogram it, you'll need an AVR ISP programmer.…
-
Sorry-- didn't see your message until you had already found the answer. The "canonical" guide is the Sanguino: http://sanguino.cc/hardware
-
So my best guess as to the root cause: You pressed the bent-over LEDs down to the board *really well,* enough so that the little barbs just below the lens plastic cut through the solder mask, and into the traces below, causing some sort of short cir…
-
We actually fabricate the target boards in quantities of 500 or more, so it's somewhere between low and high volume. I'd recommend OSH Park for small quantities-- their quality is impeccable, and the pricing is quite good.
-
Yes, these were 1-2 Hz kind of motion. It's visible to the eye if your gaze is fixed-- but (like with most POV devices) you won't see it if you follow the electronics with your eyes. If you make a shorter pendulum (so that it will have a shorter p…
-
Yes, that looks like the likely explanation; the standard Arduino ethernet shield can draw 150 mA on its own, so you probably need around 200 mA total capacity. I don't know of any device that can burn that much power and can fit in the TO-92 locat…
-
*At the moment* it is working perfectly, with a couple of asterisks. We'll be contacting you offline about it.
-
In the Finder, from the Go menu, select "Go to Folder..." and enter the following: /Applications/Inkscape.app/Contents/Resources/extensions
-
Well, it was worth asking. One way or the other, we'll get you taken care of-- I'm just hoping that we can understand the failure mode, too.
