Re: ROUND 4 - CHEAP 445nm 5.6mm (true-blue) diode group buy. need 3 money sent

I also ordered the motors i intend to use for my spiro. They are the omron b5a These motors are super thin at 2mm, and they have a footprint of 11mm square. I chose these motors because of their thin profile. They will have to fit within the space i am creating for them on the sled, which is...

Today I ordered some of the technology that will be going into my project. First the unique way of controlling the laser programs and options. If you have seen FMLs white mixing kit then you are familiar with it's program and option button operation. Since i am programming my own...

I bought a 4 axis CNC machine as a birthday present to myself about 6 months ago and i've managed to get pretty good at it. Its been about 2 months since i've snapped a bit or made the machine do something really dumb. I also have all my fingers despite considerable effort on my part to loose...

thanks for the tear down morgan. I've been busy with another project at the moment, and I ran across a different set of motors that I intend to use for it. So experimenting with these steppers is on the back burner for me. Check out these super flat vibro motors tho. I hope to use them for a...

i remember 2 years ago at christmas time they had 30% cashback. It was crazy.

if you really want a blue, i'd recommend PMing him on ebay. It took him about a month of me reminding and asking for a blue, but I eventually got two ordered.

There is a guy on ebay selling 5-10mW 473nm DPSS lasers for $87 shipped. You have to keep an eye out for his auctions or you can PM him and have him send you a paypal invoice like i did and get your hands on some blue light for under $100 eBay My World - science-surplus All of his ebay...

i just finished taking the motors out of my two new sleds last night. Plastic housing on one was destroyed and the ribbon cable was already cut. On the other i have the housing intact and the ribbon is solid all the way to the sled board. I'll see if any tests on the board provides for easy...

kean, what you need are some linear diffraction gratings. Check your with your university's physics department. They will have some that should be able to do what you need. edmund scientific has some nice laser experiment kits as well. Laser Pointer Education Experiment Kit - Science Gifts -...

The worm gear on the 6x/4x motors are a lot smaller. I was planning on leaving it as is and mounting any optics/mirrors directly to the shaft. Here is what the 4x motor looks like, note that taking off the ribbon probably destroyed the leads. I have 2 of these motors at home with broken leads...

All bluray sleds these days have a small micro stepper motor that uses a screw drive to move a lens assembly. You can see it in the lower left corner on this 12x sled. The motor appears to be a bipolar stepper motor (thats why they have 4 leads) and likely works similarly to the larger stepper...

also, regarding the faceting. The facet resolution i used to make the part in the pic was .5, i can go up to 10 which would result in no faceting. I'll be doing this for the acrylic piece i am working on now to show the difference. The acrylic will also be getting a second pass. The higher...

with regards to the cuts, that is only the rough pass and only in the X direction. A second pass with a smaller bit in the Y direction would smooth it out. Some sanding helps too. As it stands, my camera also picks up the rough angles a bit more than what is obvious. It is pretty smooth to...

I use deskCNC for my CAM and control software. Machine size is: 5" verticle 14x28" bed. 4 axis i can do ~3" round.

some pics of a part i just completed. How do i make them into thumbs?

What material do you want this in andy_con? I'm guessing aluminum. I also need a thickness for the second part, only 10mm x 10mm is given. Is the cut at the base of the groove a circle with d4mm, or some other arc?

I have an acrylic project i'm working on now, i'll post some pics when i'm done. Waiting on a foot of 3" dia rod to show up at my door, but i should have some pics of it after christmas. Machining aluminum parts for it today. Expect to see some laser stuff and PCBs in the next few weeks also.

I recently aquired a nice CNC machine for my shop. The machine is capable of 4 axis milling with accuracy of 1/1000th of an inch. Projects that can be made on this machine include: PCB etching 1 or 2 sided engraving custom heat sinks custom hosts small parts cut plates (signs, letters, shapes)...

Re: Calling All RPL Owners Not a real RPL, like JayRob i own a susie/Sandstone/O-Like model Model/Wavelength/Advertised Power Susie/Sanstone/O-Like 532 250mW Divergence value <.2mRad Peak/Avg. power value. 300mW/~270mW Is the power constant for the first 5 minutes? dunno i don't leave it...
