LOL, maybe its a banking conspiracy because there could be an uptick in overdraft fees as a result of waiting before the ACH debit is sent.

What do you mean "Aside from" ? that's part of the fun! :D

Re: Amature Rockets Too funny. I've lost some of my best rockets when moving up to bigger motors. I've come to learn recovery of the rocket is the single-most import aspect of the hobby. If there is risk I cannot recover said rocket, it becometh wise not to launch it. :)

it works fine for me, several computers and OS's all using FF.

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please Contact this seller and tell them I sent you. Ask if they any Greenies lower than what's listed. I've purchased from them before and highly recommend them. They have coffers yet to be emptied.

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please I have one of these, but she is dead. :( I may have an extra remote, though. Good luck with the bidding. :)

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please clean-looking find. :)

I'll be happy to buy her a Quarter Pounder. ;)

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please Wow, OD +7? That's some serious attenuation. :D

Well done, Splat. The Haig mount is a great start. I seem to recall there was some kind of error introduced because the screw drive is straight, instead of curved. But for tsk's needs, this may be just the ticket. +1

Hmm, interesting challenge. It's too bad you cannot use a wall clock, and it's clock motor to rotate the camera. It's slow and smooth enough. But the speed doesn't vary, so that won't suit all your needs. Gear reduction is your best bet. An electric motor won't likely have small enough...

Welcome Alex, This is a fun place to learn and experiment. I hope you enjoy California, too. :)

They ARE exciting times. But I think until there is widespread use of these other wavelengths, the supply and demand principle we all know and love will continue influencing our costs in the surplus and hobbyist community. For example, the wonderful 2000mW 445nm diodes we enjoy (and are...

Photobucket does this for me. I simply upload the image, and it provides me a link to the larger and smaller images already formatted as SerpentSlayer indicated. imgur.com may do this, too, IDK.

You want to use visible light, focused to 100 microns, is that right? To do this, you’ll need optics to first expand the beam, and then focus it down to a tiny spot. But that, of course, makes the (depth of field small and) focal length critical. Meaning you’ll have use an XYZ table to move...

Re: Two quick questions about JDSU cylindrical argon heads The PSUs are easier to find in 120V than the fans. I know where to get fans, the exact one mentioned in the docs, but they're pricey, over $200 each. :( The hardest thing to do elegantly, in my opinion, is finding a clean reducer...

I struggle with this, too. The only way I know how to attach a larger image, but link thumbnails inline with my post, is to host them offsite. I use photobucket. I then copy link from PB back to LPF posts. The only downside is I can never move or organize the photos, because the links get...

Re: Two quick questions about JDSU cylindrical argon heads your are correct. The diameter (or radius) is hard to spot in the docs, but it's there. 3 point something diameter, 4-inch ducting into the input port of a squirrel cage fan. I have a spare PSU and spare fan that run on 220VAC if...

Re: Amature Rockets Nice. If you use a G motor, you better be in the desert and have a vehicle to go retrieve it. Sharp eyes and binoculars will be needed, too. :)
