--- Quote from: markronz on June 03, 2009, 05:29:20 pm ---I should have guessed that. ;D The official directions from the Led-Wiz device mention using an "in-line fuse" Would I need that for my set up? If so, where would that fit into the picture? --- End quote --- It wants to go in line with the 5v source before it reaches any of the loads (LEDs etc). As for fuse size, add up the current used by each load and then select the next rated fuse above that. --- Quote from: markronz on June 03, 2009, 07:40:13 pm ---Ok, so I am sort of piggy backing onto my own post here. I came up with another question. I bought some terminal blocks but I am afraid that I'm not sure how exactly they work. Is the wire on the one side one single wire that's just looped over and over? And then the LED's all wire up to the one side? --- End quote --- You got it :cheers: You don't even have to use terminal strips if you dont want to. You could just piggy back each anode to each other. You could also use a buss bar: This is basically a terminal strip but all of the terminals are already linked. You would just attach the 5v to one side and then connect each LED to the terminals. I would advise using a linked terminal strip or buss bar over just piggy backing the anodes as its much easier to trouble shoot and change out LEDs etc if you have a problem or for future maintenance. There are quite a few ways you can connect them up. I mounted some of mine in project boxes and used d-subs. I also did something similar in another project with an LED Wiz and GP Wiz. |

Ok, so for the fuse part this is what you said earlier: --- Quote ---21x30ma = 630ma + 100ma from your trackball kit = 730ma --- End quote --- So I would get a fuse holder like this one: http://www.radioshack.com/product/index.jsp?productId=2102784&numProdsPerPage=60&retainProdsInSession=1 And then a 1.0A 5x20mm fuse like this one: http://www.radioshack.com/product/index.jsp?productId=2103770 That sound about right? And as far as placement of the fuse holder (with fuse in it obviously), I've attached another picture. Does that look correct as well? |

No responses yet, but I'm pretty sure that's where you meant for me to put the fuse. Let me know if that's wrong. I thought I'd post one last picture of how everything will be set up. I thought it might help another newb some day who might have a similar situation as me. So if anything's wrong, just let me know. Otherwise thanks Franco and everyone else for the help! |

If you look in my post above I did put the fuse in the same place as you :) I'm no expert but I think that rating fuse should be ok. I'm sure someone will correct me if I'm wrong. Good luck with it! :cheers: |

Oh man, I'm so sorry! You even connected the two terminal blocks together in your picture too. :) I looked at the post on my cell phone originally, so I didn't see the pictures. My bad! I'm still waiting on the buttons, but once I get them I should be ready to wire it all up! Thanks again. |
