It is an electronic load that blows hot air in your face, and has female "safety" input?  That is a real winner.

That fan looks to be a sucker, not a blower.

I bought one of those Kogan DC pedestal fans. I like how it has a very low minimum speed setting compared to the $10 cheapies I have from Bunnings.

At the lowest speed it only draws a couple of watts for a gentle breeze which is perfect for sleeping. The $10 fan draws 30W/36W/40W for low/med/high, so it might pay for itself if it lasts >10 years ahahah.

I decided to bite it and bought a YubiKey Neo authentication and cryptography module.

What sort of things are you planning to use it with? General web service account login? Or computers you administer that are on the internet?

General Web services and PGP. Maybe also as login keys to my computer.

A FE-5680A rubidium reference clock, and fans, more and more fans!

On the fast track to time nut? I got my volt nut derailed after I bought my LM399's.

Now I think I need a GPSDO.

I already have a GPS-disciplined DS3231 TCXO on a Raspberry Pi set up to be my Stratum 1 NTP server inside my home network, and I have set up all my local computers (including the authentication server) to use that as the clock source. Usually I use GPS PPS as the synchronization pulse, but when GPS is flaky it switches to the DS3231.

We use those at work.

I do know that a few companies do use those for work purposes.

Dow do you use them though?

Same here. 2FA is required for all employees in my facility. The second factor could be a YubiKey, or could be a text message.

I have a pile of 2FA kit for use with various contracts I work on, it's quite common.

HP 410C Voltmeter in mint condition with accessories.
One has to resort to 60s technology to have a meter with 100Mohm input impedance up to 1500V
Also for non-believers of the unique piece of technology this is, here is it measuring a 50Mhz sine amplitude, put out 500mVrms, measured 520mVrms

Can those be wiped and reused? YubiKey can be wiped of its contents and repurposed.

I suspect not by the end user, there must be a way to get your 'secret' onto them and they must be registered somehow as they can be revoked but the back end is not something I have access to.

I have torn one down after it had been revoked but other than a set of programming contacts there's nothing that looks as convenient as the Yubi

Depending on what technology they used, it might be reprogrammable. At least (if you can find the documentations and if it is Flash reprogrammable) it can be wiped of all data and programming and you can build your own crypto code into it.

That's a beauty, especially getting all the accessories with it.

You can turn $3 stlinkv2 clones (or the Blue Pill dev boards) into a "gnuk", (similar to Yubikey) dongle.

Just noticed a folded paper that was beneath the meter, can't believe they made each scale unique for each instrument, now I get why it is so accurate.
Tektronix and HP, the best companies ever to exist !

Nice bit of kit but I'm sure you get better input impedance with digital, like fluke 8842A and hp3478a meters?

Unfortunately no, the standard in bench dmms is high impedance below 10 or 30V, like 10G, and then 10Meg and up to 1000V only, for the 3478A, 34401A, 3458A, etc...  I'd prefer to have a higher flat input R and up to a bit more voltage like 1500 or 2000V.
4.5 or 5.5 digits mean nothing when just probing causes a 30% change in the signal. I understand that oscilloscopes need to keep input Z low, but never got why the standard for DMMs is only 10M, when compensation is not needed.

Ups, nearly hit the "buy now" for a Fluke PM6681 universal counter on *bay without thinking.
Managed to check the feedback profile first as fast as I could and then hit "buy now":
In fully working order and overall very good shape for $260 including shipping and customs I couldn't stand it.   

Now waiting for it being transported from the US to Germany..

Actually quite clever, do not design the electronics with expensive high accuracy components, just adjust the readout meter.
Could be something we can re-use in this century as well if we make "intelligent" meters.
It just has to display the correct value for the incorrect internal output.
