As a result I haven't actually put the components on the protoboard yet, they're still spread out across a solderless breadboard. I do have a Fritzing diagram though, and I'll see what I can do to clean that up and post it.Bill Owenshttps://www.blogger.com/profile/08049211051802893173noreply@blogger.comtag:blogger.com,1999:blog-2054406559663992319.post-14490038810409275232015-06-22T10:46:06.848-07:002015-06-22T10:46:06.848-07:00Do you have a photo of your completed Adafruit pro...Do you have a photo of your completed Adafruit protoboard? (or a wiring diagram) I ordered everything from the BoM you posted and I'm looking to get the Darlington and everything else all sorted out and wired up properly. My 3d prints completed last night. You made getting the parts pretty simple, thanks. :-) Usually people do the opposite, detailed assembly instructions, with no BoM for where to get never before seen parts.Anonymoushttps://www.blogger.com/profile/00238227062316716808noreply@blogger.comtag:blogger.com,1999:blog-2054406559663992319.post-7062550583212736402015-04-02T06:50:00.538-07:002015-04-02T06:50:00.538-07:00I can't seem to put links in the comments even...I can't seem to put links in the comments even though I'm the blog author, but I think that if you search for ATLAS 3D Users it should come right up.Bill Owenshttps://www.blogger.com/profile/08049211051802893173noreply@blogger.comtag:blogger.com,1999:blog-2054406559663992319.post-3391752592576075242015-04-02T06:34:43.521-07:002015-04-02T06:34:43.521-07:00I was wondering what the name of the Google+ group...I was wondering what the name of the Google+ group you're referring to.

I didn't realize that you had made the lasers straight out. I will do that too. I think I'll tie the camera and lasers all together in a one piece fixture so it all moves together. <br />I am putting the camera on a gimble so I can put it in any orientation I need for the the calibration to the turntable. <br /><br />I will try to hunt down that Google+ link. I am a novice to Google+, can you tell me which group do I need to search?<br /><br />I can't thank you enough for the feedback/help. <br /><br />(If you ever need cad models or 3d printing I will gladly pay you back. I have a Fusion3D printer, so anything you need printed just let me know and it's yours. It will do up to 12x12x12 inch printing size.)<br /><br />Thanks again,<br />TravisLoded Dyperhttps://www.blogger.com/profile/01760784023856105785noreply@blogger.comtag:blogger.com,1999:blog-2054406559663992319.post-81200218151612138722015-03-31T12:10:07.764-07:002015-03-31T12:10:07.764-07:00The relationship between the lasers, camera and tu...The relationship between the lasers, camera and turntable is hard to explain, but Uriah posted to the Google+ group a few weeks ago with a diagram that helped. Unfortunately I can't link directly to it, but if you search the group for his postings it should come right up. I think you're best off keeping the lasers at the same height above the table (which is the Y value) but Uriah maintains that it doesn't matter because the lasers create a plane of light. Likewise, the lasers can be closer or further away from the table radially, but what you need to measure for the X distance (right and left of center) is where the plane of the laser intersects the focal plane of the camera. So keeping the Z distance physically the same for both lasers and the camera makes that measurement a lot easier. Does that make sense? That's why I set up the Piclop to have the laser arms straight rather than angled, like the original Ciclop design.Bill Owenshttps://www.blogger.com/profile/08049211051802893173noreply@blogger.comtag:blogger.com,1999:blog-2054406559663992319.post-17749020608579526962015-03-29T15:08:03.670-07:002015-03-29T15:08:03.670-07:00Bill,

By that I mean does the camera and lasers need to be on the same "Z" plane (for lack of a better description)? (The scanner I'm designing lets the lasers and camera slide up and down and lets the turntable move closer and farther from the camera depending upon what needs to be scanned) I'm re-designing the whole scanner as far as the hardware is concerned. And I know you have the hybrid version up and running. So I'm hoping to skip some design iteration time by picking your brain...<br /><br />Thanks,<br />Travis (again)Loded Dyperhttps://www.blogger.com/profile/01760784023856105785noreply@blogger.comtag:blogger.com,1999:blog-2054406559663992319.post-79462300491286680102015-03-29T12:27:29.232-07:002015-03-29T12:27:29.232-07:00I bought extra since it's cheap, but I think y...I bought extra since it's cheap, but I think you would only need three 3-foot pieces. The cross-rods for the laser holders are 11.75" each, the two long rods in the base are 15.5" and the short rod in the base is 12.5" but none of those dimensions are critical, as long as they're consistent. You could easily make it a bit bigger or smaller without causing any issues since you're going to need to measure the finished scanner in order to calibrate FreeLSS.Bill Owenshttps://www.blogger.com/profile/08049211051802893173noreply@blogger.comtag:blogger.com,1999:blog-2054406559663992319.post-22389292437600537962015-03-29T11:30:16.339-07:002015-03-29T11:30:16.339-07:00Hi Bill, I've printed the turntable assembly a...Hi Bill, I've printed the turntable assembly and I'm about to print the camera case and tower.

I would like to ask a question about the camera:<br /><br />Does it matter if the camera is mounted right side up or upside down? (I want the cable to go over the top and was wondering if that would cause a problem with the software or hardware).<br /><br />Thanks in advance,<br />Travis CaywoodLoded Dyperhttps://www.blogger.com/profile/01760784023856105785noreply@blogger.com
