I saw a thread on these but now I can't find it...

I have a question on this if anybody can help me:
http://cgi.ebay.com/50mw-tunable-53...7634100QQihZ002QQcategoryZ53141QQcmdZViewItem

I sent AixiZ a message but they have not responded yet.

I just bought one of these and I want to test it, but first I want to make sure of the connections...

Here's a picture of what they sent me:
AixiZ green.jpg


It says this in their description: "The units are rated at 50mw 532nm with 90-240VAC and TTL modulation control" This means that I power this board up with 110 AC wall plug correct?

No instruction sheet. I'm sure that the large plug-in lead is for the AC input, but does anybody know what the small plug-in lead is for? Maybe just for a switch??

Please help...
Thanks,
Jay

Yes.  The "big plug" is for the mains power.  You can just plug it into the wall socket (after wiring on a plug )  ;)

The smaller plug is used to hook the laser up to a TTL modulation circuit.  The little socket on the board (for the little plug) should actually have TTL printed on the board next to it.

Peace,
dave

Thank you Dave...

Not familiar with TTL modulation. Something for controlling the laser for light shows?

Anyway, I don't need to worry about it right? Just plug in the big plug to test the laser and the TTL is not needed correct?

I just didn't want to plug this thing in with out understanding about the other plug first...

yup just plug it right in!

You are correct, the TTL is modulation for light shows. Also known as 'blanking', the laser will shut off when voltage (I think it's 5v....) is applied to that smaller plug.

I believe analog modulation works in the opposite way, where the laser wont work unless voltage is applied and you can change the power of the laser with different voltage levels.

Have you powered it up yet?

Mine showed up today. I do not have it in an enclosure yet, but I fired it up in the garage just to make sure it worked. When I first powered it up it just pulsed. I removed the sticker and found it was set on what I am calling 8. After turning it back down to 7 it ran fine but would not go under ~4. After letting it run for about 15 minutes I was able to turn it up all the way and be able to adjust it down to almost 0. For what I need I will only be setting it about 4.

I have some beam shot, but I can't post them yet, need 10 posts.

Just got done. VERY happy! :D It powered right up to 65mW's, and stayed above 60mW's. After about 2 minutes, it leveled off at 67mW's.

Didn't keep testing, but it seems very stable. The block heatsink didn't feel any warmer. I have no desire to mess with the setting on mine!

What a great deal! :cool:

Neither of mine have gotten hot. One is running at 98mW and the other is running at 130mW. Now mine are the "earlier" model so YMMV. When one gets put into a scanner, I will turn it down significantly. However, with that said, at 67mW you should be able to run them continuously.

Peace,

Thanks for that info Dave! I just ran a 20 minute test. I am very impressed with how stable this thing is. It slowly fluctuated a little between 66mW's and 69mW's, but most of the time it was stable at 67.6 mW's.

After 20 minutes, the 'block' heatsink only got 2 degrees warmer. Not even enough to feel the difference. I only could tell with my IR digital thermometer. Cool! :cool:

WOW thanks for posting this.. i saw someone buying this earlier (in july) and i thought they were sold out of these. crank up the power on yours and see how much you can get :D someone else got 120mw i believe

I'd rather not mess with it, Im going to put it in a 3 mirror spirograph! So I'm not trying to see how much it can be pushed...

Just like it stable. Pretty good deal though!

YEA! i couldnt' remember where i found it :D how are those TEC's working out for you?

btw, i might need you to make me another heatsink depending on whether my friend wants a laser :D i'll keep you updated

The portable TEC Ice Box project it really a cool project to build! :cool: And it works very well...

Cheap too! At least the project box, peltier, heatsink, and fan... those parts are all very inexpensive.

As far as specific information on the peltiers, I'm no expert on them, but I know that they need a heatsink and fan to dissipate heat from the 'hot' side in order for them to work properly. And... Gazoo was running them at 350mA's. (I'm running mine at 500ish mA's)

Anyway, just let me know when your ready for another heatsink!
