There is an app (for Android) called SpeechJammer that does something like this. When I saw your instructable, I got curious to see how it would work, so I downloaded this app (has an adjustable delay). So, my findings (for me, anyway) are that it doesn't work on me. I tried various settings...

With the exception of there being 5 BlitzLinears left instead of one, everything posted is left.

Yup. Haven't sold some things in a while. May lower prices on a few items.

Pman, unfortunately, you're the exception :( I only had medium flat rate boxes, so I felt it would be a waste to ship something so small in such a large box. My brother will grab me a small one tomorrow though so I should be able to ship them tomorrow!

Alright, OP updated with current items for sale. The Lumintop, prisms, HeNe, BlitzBucks, and some BlitzLinears are gone.

Gotcha! I'll be sending out all of your packages today :D

Alright - so already spoken for are the big box of electronics, the BlitzBucks, and 6 BlitzLinear drivers. Will update the OP.

You are correct - it is built for a 5.6mm diode. The correct definition ;)

Three more pictures of the Lumintop Silver Fox: Potentially the best part of this host is the tactile switch at the bottom. It's also stainless steel and it is just a nice little push feeling. No click, just a push. It's really quite amazing.

Sorry I didn't respond to stuff today - went to see Interstellar with the fam and then was out with the fiancee. Anyway. Glad there is interest in this stuff. Tomorrow I'll put up a pic of that Silver Fox Lumintop. I'll try to get some nice ones, but if you search Silver Fox Lumintop that...

Hi everyone. I know I haven't posted in a while because I've been really busy with school and the fiancee (recently got engaged!). Anyway, I basically haven't done anything laser related in about a year, so I figure it's time for me to sell most of my equipment and things I am not using - I...

My guess is that it's linewidth, to be honest. I've thought about myriad ways to direct double, and it all comes down to the fact that you need a narrow line for your pump :\

Agreed.

I think you guys are being overly harsh on ARG. In the first post, he explicitly says, That being said, there was an understanding that someone would receive the diode. However, that was by no means guaranteed. What if the diode we received had been defective? What if it had gone out right at...

There's also always the LM1117 for low power options, which is more efficient than the LM317, and then there are the LM1083-LM1085 for higher power, more efficient options. Be these are slightly more expensive.

The green in that generic laser is most definitely 532nm. So you're good there.

Fortunately, any green laser you see for under $20 will be the 532nm DPSS laser. So, just pick one up on the eBay. Because of the nature of the physical process used to produce the 532nm light, it doesn't matter the "quality" of the laser. So if you can find a green laser for under $20, that's...

I understood what you meant, but I think it wasn't clear in your original post, so I clarified. Because he is looking for wavelength stability because he wants to calibrate a spectrometer, power means almost nothing.

The problem with diode lasers is that they drift as much as 5-10nm in either diirection. My personal 405nm runs at about 411nm (spectro'd in the laser lab at the university). Bionic was wrong - for wavelength stability, DPSS is the way to go. I would suggest using a 532nm laser most definitely...

You are entirely right. I have a solid silver host, known to have great thermal capabilities, and it clearly gets "warm to the touch" after a short 20 seconds or so. However, sometimes, if the heatsink is properly designed and made out of a clearly effective thermal conductor (like copper or...
