So does that mean I connect both grounds of the adapters together so there is are 3 total outputs (ground, +, and -)? Sorry if this is dumb question. I found this article: How to Build a Robot Tutorial - Society of Robots Is that kind of what you are explaining? I haven't worked with positive...

So just to be clear for all the points in the circuit that have the ground symbol, I just hook those up to the - output of the wallwart? Yeah idk why this circuit asks for 14v instead of 12v. I'll try 12v, I really don't think it will matter enough to cause problems.

Drawing large amounts of stand by power won't be an issue because the whole thing will just be sitting on a table. I'm not too concerned with efficiency or power usage because it's not intended to be portable. I'll try the wall warts though. Those sound like a better idea. I completely...

So that's how it works. Thank you! I couldn't find that anywhere. :D I'll order the parts later this week and get to building it. I may have some more questions later if something doesn't work but I should be good for now. :) I'm going to try and use a computer power supply in place of the...

Sorry about not rotating it. I fixed it. Didn't notice that only 2 were through hole either. I had hit through hole to filter the results or at least I thought I did. That narrows things down a lot. That's interesting, I didn't know the 1/2 referred to only using half the chip. All of the...

I'm trying to build the circuit attached. I'm having a little bit of trouble with the amp side (red outlined section) though and finding the correct ICs. I looked on Digikey and Mouser but am not sure which to get. The diagram says that I need the TL062. However when I search for that I get...

Thanks! I was looking for that thread. Which company/brand is that flux? That's what I was trying to figure out. Is it amtech or kester?

I bought some flux on the forums here awhile ago and it worked great but now I am out. The syringe didn't have a name on it or anything so I don't know what company made it. It worked really well with surface mount soldering and non-surface mount. It was a no-clean kind. Do you guys have any...

Can you adjust the current on them or are they fixed at either 1.25a or 1.8a?

I think you misunderstood me. I should have been clearer. I know we don't work with voltage but if it doesn't start to lase at 3v 80-100ma then it should start for sure at 5v 80ma. It's either blu ray or red so it has to be one of those two voltages. I wasn't saying that I would keep...

Yeah the diode, I think is red, has 3 pins. Maybe it's a bluray then. I'm really not sure. I know I had 2 phr sleds and I took the blu-ray diodes from them. I have no idea what this one is. It looks much more blue on the lens than any of my 6x or phr blu-rays diodes look (all of those are...

I'm trying the glass trick now. By yellow do you mean a goldish color? If so then I think I have 1 blu-ray and 1 red. Which would make sense since I believe these both came from a phr sled. Do you know the exact name of the red laser diode and how many mw is typical for it?

I put a few diodes in axiz modules and mistakenly never labeled them. Now I have a bunch of axiz modules and I don't know what diodes are in them. Is there anyway to test them to find out which diodes are in which without burning them out? I know they are either phr diodes or red diodes...

I'll give it a try. If I can't shove a flexdrive in there, I'll make it driverless.

There isn't even enough room for a lava driver? Great build by the way. :) Good idea with the spacers too. Is it easy to screw the laser assembly out? On the hosts I have it's very difficult to get led assembly out. I think it might be even harder once if I but a laser setup inside. I was...
