I don't see any straightforward way to do this with the same basic architecture, if it has to work with two-pin LEDs. There are, of course, ways to do it, but it would require a very different design, since both the row and column drivers assume tha…

@orenjacob Does the servo motor make any sound, at any point, for example when you launch RoboPaint? Please make sure that the servo connector is connected to the correct port of the EBB, with the black conductor towards the outside of the EBB. If…

@orenjacob I see that you posted this to our github issue report as well. It would be helpful if you would pick one place so that we do not have to have the same conversation twice. On the RoboPaint RT issue:Can you please say which version of Ro…

@dfwdennis: We have posted a new version of RoboPaint RT that seems to fix this issue (so far as we know-- we have still not been able to reproduce it locally), available from our list of releases, under the name "RoboPaint.RT.Mac-20140101.zip".
-
Great-- Thank you for confirming the fix, and again, I apologize for not having patched our installer yet. I should be able to get to that shortly.
-
Hi Mike,We've just had a report of this from another user, and I apologize that we have not had a chance to update the installer file yet. We believe that the issue is due to changes made from version 0.48.2 to version 0.48.4 of Inkscape, so you c…
-
Awesome-- I'm glad that it turned out to be straightforward.
-
Please follow along with the advice in the other thread, here, about how to double check those mechanical parts, and adjust the current if necessary: http://forum.evilmadscientist.com/discussion/comment/911#Comment_911 If the tension seems correct, …

Hi Sha,Fantastic-- very glad to hear it! When you get a chance to try a test print, I'd suggest running your first one without a paintbrush inserted-- make sure that it looks like it's doing everything right before using up any more paint and paper,…
-
Hi Bud,I apologize for the slow reply-- I was busy in another thread. Our usual strategy is to loosen the screws that hold down the cable guide at each end, and to angle it upwards-- up out of the carriage, and up out of the cable guide support on …
-
Hi LongArc,I spent so long on that first reply that your first and second comments came before I had a chance to reply. I'm glad that you've got it working!
-
Hi Sha,I'm sorry to hear about the difficulties. There are several different issues here, and we need to work through them one at a time. First off, I'd suggest putting away the paint, water, and paper until you can tell that the machine itself is …

The Hatch Fill extension is without question the best method to use for text. We also describe some other methods of filling regions, here: http://wiki.evilmadscientist.com/Creating_filled_regions
-
Possibly the same issue as this: https://github.com/evil-mad/robopaint-rt/issues/15 If so, you'll be able to run from source, but not from the standard distribution. I've uploaded a new test version that you might try, linked in that thread as wel…
-
I would too.
-
To clarify a bit: When we talk about "cogging," we are referring to cases where the motors are effectively skipping big steps, and losing track of where they are supposed to be-- for example if the carriage does not return to the home corner (but go…

The SVG images that StippleGen saves are pre-formatted to be used with the Eggbot, but it's straightforward to use them with the WaterColorBot instead. Note, however, that stipple drawings look great when drawn with a pen, and not very good when dr…
-
Hi Chris, I'm glad to hear about the (partial) success-- and we'd love to help you get the rest of the way there. We have generally found that when a WaterColorBot is correctly tensioned for the first time, it will need to have some additional slac…
-
Hi Fletcher,Thank you again, that is very helpful (and confirms that the "crash" bug is in fact a known text-handling bug in the latest Inkscape version). I am sorry for the continued trouble with the Eggbot connection; I'm not yet sure what the i…
-
OK-- thanks! Very interesting! If the "Name Poem" too is crashing, then this likely isn't a machine control issue, but could be a matter of text handling (or something similar). We do know of a related issue, specific to Inkscape 0.48.4, that wa…
-
Hi Fletcher, I have heard of a similar error twice before-- neither in the last 12 months --and I wasn't able to get any debugging information about what could have caused it in either case. So, I am sorry for the trouble, and you very likely aren't…
-
imatool, Yes, the Art Controller can be triggered by any low-going signal. However, that is a term that has a specific meaning, and if you cannot provide an appropriate input, then it will not work correctly. > If a buzzer makes a sound it is …
-
Hmmm... Well, I'm not sure exactly what happened, but I'm glad to hear that it is working now.
-
>What little I know about them, you are saying that the capacitor will act to collect voltage and smooth out the signal which might trigger the art controller? No, not at all. Just that if you can't provide a valid DC signal, you might be able …
-
I would expect you to need two wires from the clock to the Art Controller: A common (ground) connection, and a signal from the buzzer output to the Art Controller's trigger input. With a single wire (no ground connection), it may trigger, but it ma…
-
I'm sorry to hear about the problem. There are a few failure modes that would cause it to totally cease operation. Most obvious: No power. Check that the batteries (if using) are good, or that your plug-in 5 V power supply is good, and that the …
-
Yikes! And, that sounds like a fine solution. I've lived in places where I ritualistically touched (grounded) door frames when I walked by, to keep from developing an ESD-dangerous charge.
-
That's a good point; I was thinking of a possible problem on the analog side. You're absolutely right that this could be a "PWM" type problem due to a clocking or interrupt issue. (And if so, it would be the first time that I've seen it.) jgr4: Wo…
-
I've never heard of a servo motor doing that, so there may well be something wrong with it. I cannot imagine a situation in which the software or interference would have an effect on that. I suppose that a power supply malfunction could cause somet…

We have actually strapped an 'XX8 board into the battery compartment area, which (we thought) worked surprisingly well: http://www.flickr.com/photos/oskay/3287679666/ (This was part of the "old school" TWI method of getting video onto the …
