Carbon Dioxide Laser) and it shines on a mirror. Does the mirror reflect the laser, or the laser burn through the mirror, and why? <br /><br />If the mirror reflects the laser beam, is the beam's intensity still strong enough to cause damage? Would be better if the approx percentage of the intensity is reflected.<br /><a href="http://spawrcopperlaseroptics.com/" rel="nofollow">Laser Technology</a>Rose Mariahttps://www.blogger.com/profile/04080536952744694488noreply@blogger.comtag:blogger.com,1999:blog-426654161750451120.post-75079307450379394762014-10-17T04:52:45.670-07:002014-10-17T04:52:45.670-07:00Hey,

I'm trying to see if I can replicate this project and am pretty excited about it.<br /><br />If you get some time one thing that would be awesome would be links to the parts you're talking about - I'm googling some of them and get no hits at all, so I'm just taking best guesses at parts, and I have no idea if I'm going to get the same part you used or not. Which is leaving me a lot of doubt about whether I'll be able to do this project without a lot more knowledge than I have yet!<br /><br />Adding links to parts would make replicating this project so much easier I can't even tell you!Evan Reynoldshttps://www.blogger.com/profile/07255595401988945249noreply@blogger.comtag:blogger.com,1999:blog-426654161750451120.post-91466584227814827452013-06-17T13:11:21.065-07:002013-06-17T13:11:21.065-07:00Okay i got a proper motor going but my uln2003 ove...Okay i got a proper motor going but my uln2003 over heats sparks and smokes. any suggestions? also i switched to a 6 wire nema 17 motor with a rated voltage of 3.5 and 2 amps will the 15 volt 5 amp power supply be to much?Anonymoushttps://www.blogger.com/profile/15786304303966302411noreply@blogger.comtag:blogger.com,1999:blog-426654161750451120.post-69450842878425636752013-06-08T12:51:44.490-07:002013-06-08T12:51:44.490-07:00@Joshua Hartman:
1) Yes it is important to send t...@Joshua Hartman:<br /><br />1) Yes it is important to send the right signal to the right path. ther right way will depend on the type of motor you are using. <br />Use this link to find out what works for your motor:<br /><br />http://www.youtube.com/watch?v=fTtwWJZlGt4&feature=player_embedded<br /><br />or search youtube for: How To Identify The Wire / Lead Of A Stepper Motor <br /><br />Use baterries first and a lot of patience..<br />=============<br /><br />2)Not sure I understad your question right here but here it goes:<br />No, dont run the wires down to 3 holes. <br />You will use only 2 conections from the trimpot. This link may help you setup yout pot:<br />http://www.youtube.com/watch?v=9Bsg6ITWHk8<br /><br />" is the far left pin of the pot in the same line as the analog input and <br />ldr?"<br />yes.<br /><br />3) the pot is there because you will have to adjust it depending on the amount of light you have in the room you will use the laser harp.<br />What I eman by this is that the room will have some light and this should not trigger the "on" state of the system to pay a note. The only way I have found to adjust the sensitivity of the LDR is using a trimpot. If you dont adjust the trimpot to base level of room light the LDR could send a play note signal before you hit the laser with your gloves...<br /><br />P.S. Always use googles when you work in your laser harp project. You can find some pretty cheap ones at ebay.comRuetehttps://www.blogger.com/profile/06859848791529435588noreply@blogger.comtag:blogger.com,1999:blog-426654161750451120.post-9858769415525557352013-06-07T19:42:05.576-07:002013-06-07T19:42:05.576-07:00Hello there I am attempting to build a laser harp ...Hello there I am attempting to build a laser harp off your design and i have a question or two.<br /><br />1, with the stepper motor wires from arduino outputs 8-11 once past the uln transistor does it matter what order the wire for the from motor goes in?<br /><br />2)I am alittle confused off the fritzing diagram about how the ldr and pot is wired i extended my pot to be on the outside of the case so do i just run the wires down to 3 holes next to each other ? also is the far left pin of the pot in the same line as the analog input and <br />ldr?<br /><br />3) what does the pot do? <br /><br />the is my first attempt at electronics so im sorry im my questions are a bit daft. I pretty much got everything working minus the above, thank you!Anonymoushttps://www.blogger.com/profile/15786304303966302411noreply@blogger.comtag:blogger.com,1999:blog-426654161750451120.post-36693680899783291072013-04-25T05:18:47.997-07:002013-04-25T05:18:47.997-07:00Hello,
