Finally got a microscope big enough to work under. I did a few leads of a QFP64 and giggled a little.

Nice setup you got!  :-+

Finally I got a label printer that I can connect to my computer. I didn't find a driver and a program that would work for me on Linux, so I hacked a solution from another solution. Took a while to make it working, it's not perfect, but good-enough.

Very nice one ! I was asking myself what that huge power supply on the right was for, I got the answer :

Quote
A 150W halogen illuminator with 35" heavy-duty fiber-optic ring-light provides the smoothest overhead lighting possible. Active cooling and auto-shutoff avoids overheating in strenuous environments.
Wow.

Have fun !

Perhaps I'm the exception, but I gave up with ring illuminators on microscopes as I found they get in the way of tools, in particular the hot air gun. Instead I use a pair of 3W LED narrow spots on goosenecks mounted opposite each other clamped to the microscope.

I have been doing something similar too for the last year or so but I am going to have a go at a softer diffused light and see if I prefer it. The spots throw harsh glare on the shiny bits even when done from the sides. I do have plenty of room under the camera on my setup so it shouldn't get in the way to much.

May I ask you, if you can measure the maximum eye distance (mid-mid) of the okulars?

I had ordered a trinokular only to find the eye distance some millimeters too short for my obviously XXXL head and sold it again.
I now settled with the zoom camera, Dave made a video about. But that's no stereoscopic view of course.

A stash of banana jacks. Building of small boxes with unsafe terminals can now continue.

I'm on the lookout for about a half dozen of them, in red and black, only in a solderable inline form. To use as extension leads to binding posts that are further away than a few feet.

"Unsafe" depends on the use, not just the terminal.

Looks like 3" and they are linked so one moves the other.

My Wild M3Z adjusts from, 45-75mm. I use it at about 70mm.

McBryce.

Exactly. I despise the shielded plugs. I almost never connect to anything at a high voltage and if I do, it's just probing with a handheld DVM - not something likely to leave uninsulated plugs lying around. Yet all my probes have them.

One of the most stupid is the Fluke 80 AK accessory that converts a thermocouple to fit a DVM. If it ever has more than a couple of mV on it, then it was connected to that with an abused and completely unshrouded thermocouple plug.

Actually arrived today from Bulgaria to Oz in 10 days  :-+ eBay auction: #173847478655 100' (30m) of Teflon covered silver plated wire. Quick 4W test got 4.4 \$\Omega\$ for the roll so 0.144 \$\Omega\$/m  so test voltages only.

Same seller and still to arrive a few more LM399H VRefs to play with eBay auction: #173362279991

I found a short length of 3/16" brass tubing (from a model shop)  with heatshrink over it made a very neat inline socket for banana plugs

Nope I wanted the Teflon outer for Voltage reasons for some test leads and connections ;)

US $25 (a few hours left on the sale)...couldn't resist...well, I could, but I really like toys :)

https://www.bhphotovideo.com/c/product/1626703-REG/sunpak_sp_4k_ac_kit_4k_action_9_piece_camera.html

So, to provide some real-world impressions now that I have had it for a while....

BLUF: At the price I paid, it is a nice.

On the price: Yes it was a special sale and the price has gone back up. But (and I knew this before ordering) Bungood sells a similar/identical unit https://www.banggood.com/SJ9000-Wifi-4K-2Inch-1080P-Ultra-HD-Waterproof-Sport-Camera-Action-DVR-Camcorder-p-1776031.html?rmmds=detail-left-hotproducts&cur_warehouse=CN at about the special sales price. BUT, B&H Photo is a legit place that I have ordered from several times over the last decade or so...never had any trouble and free shipping and it got here pretty quick.

The movie quality is, in fact, pretty impressive, at least at the highest resolution. Granted, I am much more experienced at still photography (which it also does), but still, I was impressed. Not a whole lot of controls though (some exposure control).

Sadly, there is no USB control at all: only power is being used over the USB port...that is a disappointment. There is an Android App available so you can log into the camera remotely and activate many functions. It works, but only barely.

From my searching around, it is not hackable in a friendly way....

So, that is basically it...I probably will get some use out of it as it is small and handy.

Stupid thread made me go look at ring illumination so I brought a cheap LED one. It is coming with an included secondhand Microscope for 'testing purposes'.....  ;D eBay auction: #224448558225 Same user has a hot air station listed too. eBay auction: #224448545312
