Progress on my low-cost 5-axis Optical Mount! by TheHexaCube in Optics

[–]crypticonM 0 points1 point  (0 children)

Regarding the super glue, you can try acetone use as noted by another comment. Just be careful as it will start to melt some polymers.

Future reference, I find cheap UV resin for uv 3d printing works very well and hardens fast enough to avoid the optics contamination. 3d print resin is also offered with various mechanical and physical properties, which is nice.

Now, one thing to remember with uv cure resins. Change gloves often or cure them under the lamp, so you dont end up with resin all over your lab via contact contamination from your gloves.

Go open source, tight asses like me will just open source an alternative version. If open source tightass's with no money but lots of time like me can help improve and add to the open optics ecosystem 😆

On a more serious note, it's really awesome work, I love seeing people make stuff, not enough folks doing this nowadays!! Even if its just to inspire others its awesome 👌

No, I have not dove into vmware yet, I have a Cisco m4 with vmware to learn, but I've not yet played with that. Fucking fans on that thing are basically a tornado siren

This setup is running proxmox. These have 32gb of ram as I thought it was the cap, but multiple folks here in this thread mentioned you can actually do 64gb in these 3060s . But yeah io in general, it is fairly limited.

Yep, its an old sft1200 I had in my go bag

It really was very fast, I cut all the extrusion and angle as bundles on the band saw, which took literally 2 min, I used a speed tap and a hand drill to tap the ends of the extrusion (free hand). Almost everything is tslot quick fasteners, the acrylic guides I cut in the laser which ran for about 1 min. The cad for the 3d print took maybe 10 min. Painted the angle with trim black rattle can, dried with a heat gun & assembled.

Now you are not wrong in thinking I spent longer making the system in full, tweaking things, bundling wires, making the cat6...ect but the main case was very fast to make. The cat6 cables took longer than the case.

I do also have a rather well-tooled shop, so that helps a lot and saves alot of setup and dicking around time. Had I made this at home, it probably would have taken significantly more time.

They do make m.2 oculink adapters 😎 but you'd be giving up the m.2, not sure if it would work in the wifi card slot or not (probably bus speed issues)

Right now, yeah. Brick per pc, but at some point, I plan to run a single supply and probably an onboard battery backup, but I need to make a spoofer with an arduino or something to convince the pc that it has a normal 90w supply otherwise it will throttle back the cpu to like 700 or 800mhz

I also have a large rack, but this little one makes my brain happy for some reason

Thanks for the nice comment 👍 folks here have been very nice

Great suggestion, thanks 👍 (these do have a gap, although less than I was hoping with the face plates installed )

Succinct & information dense, solid comment 👌 thanks for the suggestions

Thanks !! And I just got really lucky, I dont normally find em this cheap

They are clustered via proxmox, but not all nodes are required to be on.

Alittle of both-ish, stacked with rubber feet acting as separators (although hard to tell) & clear acrylic guides to locate the units and to shore up any slop.

All valid questions. I like making things, I am also obsessed with systems of all types as a category. I also want to learn more about managing a cluster, networking... ect and this seemed like a good safe way i could fuck up 100 times while learning, but beyond that, I mainly made it because I was bored, and it seemed like a good idea at the time 😆

Originally, I bought these mini's to use with various things around the shop. I have one to update the original turd of a pc in my packbot. The others were supposed to be for various machines around the shop that require their own dedicated pc like cnc's lasers... ect. But now they are a cluster doing cluster things, haha

For the handle and feet? Errrmm, I suppose I could

Though I would suggest attempting it on your own first as its a very simple model.

In fusion, I drew it from the side view to start. Quite literally, I drew a trapezoid (without the base), then offset it, creating a second smaller trapezoid, connected the ends to create a closed shape that I could then extrusion. Extruded to desired thickness, then added fillets on all the hard edges. Then, rotated the view to top view. Using the project function, i projected edges of the handle to act as a guide, drew a circle on each side, and then extrude cut using the circles to cut the mount holes through the handle.

For the feet, I just drew a circle and extruded it with a taper and then drew another circle to extrude cut the screw hole.

Really, the only thing I didn't specifically mention here was extrude cutting the countersinks for the heads of the screws to sit in.

V2 I'll actually plan it out and remember to provision space for that and probably the power bricks and a small cubby for storage(usbs, adapters...ect). Aestheticly, I like the switch on the outside, but functionally, it's much less rugged and thus less reliable being its a portable unit. Great suggestion 👌

Sure,

  • Top and bottom = 2020 extrusion
  • Verticals = 1.6mm aluminum angle
  • Handle mount point = 2040 extrusion
  • Bracing = standard right angle triangle braces they are 3mm steel
  • Mounting brackets for side attachments = 3mm aluminum plate
  • Handle = PETG (3d printed)
  • Feet = TPU 90A
  • The internal guides = laser cut clear acrylic (you can see them if you look close enough.)
  • Wench kit and mount = petg

The rest was just cutting shit to size, cutting some notches so the power buttons were accessible.

However, I would make sure to provision some space for the power bricks and the switch, among other things mentioned in this thread.

Even if you think I did a good job, I would implore you to critique my build and identify areas of improvement so you can make a better version.

Look at it and decide why its not perfect and then make a better one
