For a decade or two, I have had a couple of the old, vintage Luxo lamps with the circular fluorescent lamp and the big 6 inch 150mm glass magnifying lens. From the Tektronix "Country Store" (surplus sales outlet). Pretty nice, but not portable at all.
But I just bought this gadget from Amazon. Pretty nice. I'm getting another one for my tool kit.

Nice, I've been using this handy little guy - it has flip out feet plus a big clip:
I got a Nicolet Sigma 30 oscilloscope.
That's a neat looking oscilloscope. Apparently those were made for high resolution measurements in physical and biological type applications. The fact that they made a version with "an enhanced magnetically shielded RF enclosure built to withstand extreme electrical and magnetic fields" may have something to do with the unusual placement of the inputs. I does kind of remind me of some kind of medical device.
I'd say you scored.
I don't see how it can work right with the spigots on the side.
Does the screen have a 3D view mode, with the traces arranged in perspective like they actually were coming from the BNCs?

If so, that would help yes.

I'd say so too.
. It can do 100uV/div and the measurements and analysis menus smokes everything I've seen in previous scopes. Got it with new probes and only paid for a couple of ADCs

I got one of those too. It's a piece of crap. The twp LEDs don't light the area you're looking at, and the 5x magnifier inset is in the way, of the already small main lens.
I'm moving ALL my MCU/DSC projects to PSoC 5LP
smart move, did that long time ago after seeing how development times are reduced with the psoc creator and how one tool serves across psoc 1,3,4,5,....

It's ok for quick checks of things, but for serious SMD soldering etc you are correct, it's crap. That's why I bought the big bench mounted 5x unit further back in this topic.

I suppose. I got one of those desk mounted ones too, glass lens and smd LEDs. It is clumsy like all desk magnifiers, but works pretty good. I think it was a little over $100.

I'd love a binocular microscope but so far out of my hobby budget it's not funny.

I know what you mean. I had a decent Nikon stereo microscope, my father in law borrowed it a few years ago, and really liked it, and now I'm too embarrassed to ask for it back, besides I took his daughter, seems like a more than fair exchange... I guess I'll look on eBay for a microscope...

Brilliant, Thankfully my Wife's Dad and two step-dad's (complicated family) and my father all live in different states or countries so I dont have to worry about loaning them tools.
Although I do send my old man "computer care packages" every few years to keep his computer somewhat current - seems fair seeing as without him buying us a family PC in '87, I likely wouldn't be an ICT pro.

Well said and nicely done.
Two dev boards:
Orange Pi Win Plus: Allwinner A64: ARM Cortex-A53 MP4 @1GHz + ARM Mali-400 MP2, 2GB DDR3L-1600, Wi-Fi IEEE802.11b/g/n + Bluetooth 4.0, 1000BASE-T Ethernet, 4x USB 2.0 Host + 1x USB 2.0 OTG, 16MB SPI Flash (was 2MB before a hack)
Two Expressif ESP32-WROOM dev boards. Expressif is in Shanghai though.
Agilent 7 GHz probe with single ended/differential head - now where do I get a 7 GHz scope for cheap?

Well, Keysight offers the really nice 6000X scopes for up to 6 GHz
I have the scope but unfortunately no 6 GHz probe
How much did you have to pay for the 7 GHz probe?
A 'universal' 100 watt power supply, as pictured below. It has a bunch of selectable voltages, up to 24 volts. I'm using it as an expedient way to power the 365nm UV LEDs in a UV exposure box I'm building. I've stuck a 3D image of the box down there as well.
But I have to admit, I'm rethinking my whole approach to making PCBs after looking at what CNC machines can do. Less fuss, less bother, much better results. I've built a few 3D printers, so it should be relatively straightforward to throw a light duty CNC machine together. Or just buy one; there are several on AliExpress around the $300 bracket.

I'm quite intrigued by those CNC machines for DIY PCBs
Dental picks. One place had a box full of used dental picks. Bough one of each model. They looked cleaned but I will clean with ultrasonic anyway. Good to have in the tool box.
