Received clock today and found the problem: D12 had an apparent connection between the leads. Replaced it, everything seems to be OK now.
-
Perhaps you could try replacing your Time library and then restarting, in case something has gone wrong with it, or it's an older version. If you're getting the exact same error-- indicating that the Time library is not installed --there has to be …

The most likely cause of this kind of thing is if you have not yet adjusted the motor current. Please see this section of our documentation, for how to adjust it: http://wiki.evilmadscientist.com/Making_your_first_plot#Drawing_on_your_Egg

First, be sure that you're measuring this voltage at test point TP3. While I don't think that there's a design error, it sounds like you may have received a board with a bad pot or some other kind of fabrication error. You should probably con…

Okay, a suggestion. Open up the library file ( .../Documents/Arduino/libraries/alphafive/alphafive.cpp ) and on line 753, make the following change: From: Wire.write(0); // start at register 0 To: Wire.write((uint8_t) 0); // start at register…

Hmm. I just tested all of the sample code, and I don't get that error. Which version of Arduino are you using?

The Larson Scanner is designed to run off of 3 V DC, if you use the standard red LEDs. You can swap out and use larger resistors (say, 100 - 150 ohm), if you'd like to run it off of 5 V DC. As far as current goes, it's under 50 mA, max. Now, I don…

So, your two basic approaches at this point would be either (a) carefully document what the actual status is right now, or (b) send it back for us to take a look at it. Seeing as we're getting on several months now, I'd tend to advise option (b) at…

It sounds like you may have a broken servo motor. Please contact our store directly for a replacement.
-
There are a few things that you should check. First, check that all of the LEDs are facing the same way. There is a "collar" around the base of each LED, on which is one flat facet. Check that all of those facets are facing the same way. The …

The Larson scanner code is for use directly with avr-gcc and avrdude, not with Arduino.
-
I like both of the ideas-- about alternating the dots, or not flashing them. Another (more severe) idea would be to go into what we call "VCR mode," where the whole clock flashes as though it has lost power and does not know what time it is. Anot…

So yes, something is definitely wrong with either the plug, socket or board. Please contact our store directly to see about getting replacement parts: http://shop.evilmadscientist.com/contact

Nice! We have some of those GPS modules, and have considered adding this as a "standard" feature-- the one thing that we're really not sure about is how reliable it will be for people to get a good GPS fix indoors. We'll look forward to seeing it…
-
Yes, the power LED and direction LEDs will be lit if the board is receiving power from either the 9 V power supply or (if that is not connected) USB. If the steppers are humming or energized (resisting motion), then the 9V power is indeed reaching t…
-
If Inkscape is not giving you any errors, it sounds like a connection problem, as though the 9 V power supply is not connected. I'd suggest *unplugging* the 9 V power supply, plugging it back in, and trying again. Also, make sure that the EBB ligh…

The FTDI friend (a) will work, but the simpler USB/TTL adapter (b) will not work. As it says there, "This cable is not good for Arduino re-programming."
-
It sounds like you may have a bum EBB; please contact our store directly so that we can set up an exchange for you: http://shop.evilmadscientist.com/contact

Unfortunately, the plastic on *some* of these LEDs is backwards, and we didn't catch it before they shipped. I apologize for this; we probably should have noticed and included an erratum with the kit about it. The correct solution is to install …

You might start here, with one of our "Basics" articles about using LEDs: http://www.evilmadscientist.com/2012/resistors-for-leds/

It looks like the problem is that Windows 8 requires a new type of "signature" on the driver installer. Here is a possible workaround found on another site: 1. Windows Key + R 2. Enter shutdown.exe /r /o /f /t 00 3. Click the "OK" button 4. System…
-
I *think* that you are referring to the LEDs located above D21, D31, D32, D42, D43, D53, D54, D64, D65, and D16. These LEDs are all connected to signal line LED7. Check that resistor R7 is installed and is soldered correctly. Check that vertical ju…

The USB driver is not actually related to Inkscape, but to communication between your computer and the EBB driver board. I am in contact with the author of that driver about this issue, and I will keep you up to date.

StippleGen was tested under 2.0b6; I have not tested it under 2.0b7, and we do know that there are changes that affect the compatibility with some of our other sketches. For very large numbers of points, StippleGen is very slow. Depending on your …

It's better for everyone if you can get it fixed on your own, but if you do get really stuck, we're here to help.
-
Hooray! And, *thank you* for pointing out that the directions were not clear. (Hopefully, it will be a better experience for the next person to come this way.)
-
Hi John,You're on the right track. Yes, use the difference menu option to create your cutout shape. To fill a "funny shaped" path with lines, you may have better luck with the Hatch Fill extension, rather than the squiggly hatch; it handles a wide…
-
Yes, 690 ohms sounds very low. It definitely sounds like there is something wrong there. However, it may be hard to diagnose, because it seems as though something has failed partway-- not all the way open or shorted --either of which would make thi…
-
It sounds like you do not have the Time library installed correctly. If I remove the Time library from its correct location, I get that same set of errors. Your "libraries" folder should contain folders called "Time" and "alphafive," and you shou…

You can approximate this as an RC circuit. http://en.wikipedia.org/wiki/RC_circuit If 12 V draws 4 A, then you could pretend that it's a 3 ohm resistive load. Then V(t) = V_0 exp(-t/RC), or V(t) / V_0 = exp(-t/RC) Taking the natural log of both sid…
