Hi Dan,The first thing that you should do is take a look at the circuit diagram, which is available in the datasheet. ( See our documentation page, here: http://wiki.evilmadscientist.com/555 )
You will note that some of the transistors (Q5, Q8, Q18,…
I would definitely skip the resistors if possible-- and it certainly doesn't look to me like they're needed in the application that you're describing.
The note on page 12 is based upon how it is designed to work given power dissipation consideration…
It's a fine idea if you have an Arduino variant that is capable of a low-power sleep mode. The most common varieties do not, because they have additional (relatively power hungry) circuitry that runs all the time. Something like an Arduino Pro or …
Hi Gonzo,The Art Controller requires an incoming logic-low signal to trigger it. The DS3231 does have an alarm output, and it looks to me as though its output is an "active low" type that would be appropriate for triggering the Art Controller (so l…

I don't see any fundamental reason why it shouldn't work. However, the SVG files that StippleGen produces are saved in "EggBot ready" format -- that is, on a page of size 3200x800 pixels. That normally works out to 35.5 x 8.9 inches -- larger than …
I can walk you through the process, using one of our standard example files. This egg was made starting with the "traditional1-layers.svg" example file, and making a few little modifications to it:

There are quite a few possible ways to approach this. The Pixy site has info about some of the ways: http://cmucam.org/projects/cmucam5/wiki/Hooking_up_Pixy_to_a_Microcontroller_like_an_Arduino
The Peggy 2 is an Arduino-compatible board, and you c…
It is certainly possible, if you're willing to build your own custom fixtures to hold the spheres. The egg holders that come with the EggBot are designed for objects above a certain size. Issue (1) is that they don't reach far enough to touch each…
If you have a strong need to hack it, you can either use an older version of Processing, update the relevant code snippet yourself, or ask us to update it.
It certainly *should,* but Processing changes certain functions with each release, and there has been a change to the "selectinput" function since we last updated this code. We would have updated the code sooner, but we had avoided updating Process…
Several questions:- Are you running StippleGen or StippleGen 2?- Does it work correctly if you run the compiled mac application, rather than running from source?- Which version of Processing are you using?
Yes, you can set the dip switches for a 6-second activation period. (It does not fully "reset" after that-- it just goes idle to wait for the next trigger.)
The Art Controller has an on-board voltage regulator, and is designed that you can run it s…
The "trigger @ reset" option does not change whether or not it is a "one shot" -- it just makes it so that it triggers automatically (as though you had pressed the button) when the Art Controller first turns on.
Use the "trigger @ reset" option, to have it trigger automatically when it first gets power, and do not add any of the other optional jumpers.
Can you please say what wasn't clear about that in the instructions?
Your computer will definitely not be able to connect to the EggBot until the driver installed.
I have not seen this error before on Win 8 or XP. It sounds like you may not have permission to install the driver on your system.
Use this version: h…
For the green: Please download this newer version of the Meggy Jr RGB library. If you still have trouble, open up the MeggyJr.h file, and try the alternate color mappings there:

For releasin…
The error is due to some internal changes in the Arduino program since that version of the Meggy Jr library was released. I've just uploaded a newer version of the library that should fix the issue. Please give it a try and let me know how it goes…
The issue is that the blue LEDs are very bright. You can use the same range as the other LEDs, but tend to overwhelm them if turned up all the way.
The library itself is an editable file. Open it up, and look at how it works. It uses C code very s…
Certainly, the OS should not matter -- my main question, right now, is whether the issue is Mechanical (in your setup) or something else (perhaps an electrical issue, or a glitch in the file that you are plotting).
Can you check to see if it makes …
@mph:
Are you certain that it's the motor itself, actually jumping steps? It certainly should not do so, if the current is properly dialed in. What I'd suggest is that you try to plot a few circles, and adjust the current while doing so. You will …
The situation that you are describing -- where the Eggbot hardware is working, but yet it cannot connect through Inkscape -- is rare. (We do a lot of tech support for Eggbot kits. If something can go wrong, we have seen it. This is just about the l…
