Olympus CH30RF100

I recently acquired an Olympus CH30RF100 biological microscope from a local thrift store. I was actually quite surprised to see it there, and at $49.00, I couldn’t resist. As I’m still learning quite a bit about microscopy, I’m clueless on the objectives. What I’d like to find is a long working distance objective at 40x and possibly 100x. However, I understand this microscope does not have infinity optics…with that I’m not sure how to look for a long working distance objective.

Currently the following objectives are installed; A4 0.10 160/-, A10 PL 0.25 160/0.17, A40 PL 0.65 160/0.17, A100 PL 1.30 Oil Immersion 160/-.

In terms of finding an Olympus branded objective, the cost is out of my reach presently @$4500. It is possible I wasn’t looking at the correct objectives… I was hopeful to find a third of fourth manufacturer who still makes objectives for this microscope. So my question is, what specifications should I be searching for whilst looking for different objectives? Is there any brand that would be better than another? Again staying in a lower pricing tier. Finally, any recommendations on a low cost goose neck light? Any guidance would be greatly appreciated

I’m currently interested in looking at integrated circuits, specially decapped IC dies. I have found my current setup just doesn’t provide the resolution needed to see deeper into the IC.

Curious if anyone has used VOIP.MS and your opinion of the service/company?

Wanted to find out what the audience thinks of VOiP.MS: is it reliable? had pricing remained low after signing up? Anything that’s good or bad about the service?

Are shells worth anything anymore? Raider Shell on a Silverado 1500HD 78.5” bed.

Currently have a raider shell on my Silverado, that I’m ready to get rid of. It’s in fair shape I’d say, probably could use a slight recon, I’m just not up to speed on potential value.

A hole inside the stem of Hunter PRO-Spray, PRS30 & PRS40

Is there supposed to be a hole in the side of the stem of the HUNTER PRS30/40 stem? Because if there is, that’s dumb, and I’ll be heading back to RainBird 1800 pressure reducing heads. Note, this is not a consistent hole that I have found with all their spray bodies, maybe the batch, IDK.

“Scots” a new product from Western Electric

Having worked with one version or another of the descendants of Western Electric: AT&T Network Systems, AT&T Technologies, Lucent Technologies, Alcatel-Lucent (a tragic loss of from the US), and Nokia. One bit of gear comes to mind when I saw this, the Alcatel-Lucent Lambda Xtreme, with its SCOT algorithm, SCOT today meaning ‘software control of transmission’, vs the definition of yesteryear ‘software control of transmission systems’.

Wanted to share as I thought some might appreciate this.

Roots or sediment?

I’m trying to figure out what this is? No breaks have appeared yet. I suspect tree root infiltration somewhere, but it’s not killing off pressure, all sprinklers popup watering okay so far.

Water is considered non-potable, but the water district does treat it with chlorine…so far, this is the only zone with this problem.

Universal Joint(s) 2001 Chevrolet Silverado 1500HD : 4WD : 6.0L : 4L80E

Purchasing some universal joints for my pickup, and was a bit taken aback by just the sheer number of choices. Normally speaking, I’d just pickup ACDelco or GM Genuine, but their pricing is pretty high presently. So this time around I wanted to try a different brand, but I wasn’t aware of so many brands.

Just to check my understanding, the OEM joints are made by DanaSpicer? That would include GM genuine and ACDelco?

Has anyone had any experience with MOOG, SKF, or GMP? It was interesting that RockAuto was showing the GMP as the only ones that weren’t returned all that often. Not being familiar with the aforementioned AEM companies, I thought I would reach out to the experts to see what the opinion was.

Note, I have already purchased the carrier bearing, which is the kickoff point for this service.

Thank you!

I have just completed this procedure. Once I closed everything back up and rechecking the injectors were locked in, things were looking good. Started the pickup, and noted it started well, but then noticed it was idling rough. I shutdown the engine, and rechecked my work and nothing is jumping out at me as an issue. The only item that bothered me, was the EGR Tube seemed like the gasket had seen far better days. I also note what sounds like an air rush sound around that area. If the EGR tube is not making good contact, would that cause the engine to idle rough? By rough it seems like the RPMs get low enough that it wants to stall, until the gas is pressed, then it fast idles well, but when the idle drops, it again wants to stall. Would replacing the EGR tube and gasket solve this issue? Or, from what I have described to you, would you look at/check anything else? 6.0L V8 2001 Silverado 1500HD 4wd.

Hello, I have a Lenovo ideaCentre 5 desktop computer. It is getting a little old (2019), but suits my uses very well at present. Lately I have been having issues, while working the machine will randomly reboot. No warnings will occur, it just reboots. Checked the event manager, and while a kernel power error shows up “this system rebooted unexpectedly”, nothing else is showing up indicating an issue with Windows (running Win 11 Pro). I’ve looked at possible memory issues and have tested the memory via UFEI, it all tests okay. I’m zeroing in on the power supply since, as I understand it, any slight fluctuations in supplied power will cause a reboot. I’m asking here to find out if there is a definitive way to prove it is indeed the power supply that is failing? Would anyone be able to suggest ways to validate this? I do have a digital multimeter should that help to isolate the issue.
