Pretty for sure but how low can it go ?
1/10th of a grain ? That's a 70,000ths of a pound !

^ Typical smokeless propellant required weighing accuracy.

2200g x 0.01g.

Nothing special but I can put my stand mixer bowl on there and start adding ingredients...yeah it's for the kitchen.

Not bad, 0.01g = 0.1543236 grains.....nearly accurate enough for smokeless propellants.

Trust me I wanted a milligram capable balance too, but analytical balances have much smaller weighing pans and you pay for the readability with lower capacity (e.g. 1ug readability at only 2g capacity for a micro balance).

There is an upgraded version of the one I have that does do milligram at 2200g capacity, but they're extremely rare. (and this was hard enough to find second hand)

This is as good a balance as I'll ever need for cooking purposes. Arguably overkill but when I need to measure 3.0g sodium citrate for a cheese sauce I know I'm good to a tenth of a gram. (tolerances for linearity is 20mg, repeatability 7mg, corner load 20mg @1kg)

Yes I can just measure into smaller containers but god damn is it satisfying just chucking ingredients directly into a saucepan or mixing bowl. It doesn't solve the human error problem of over-adding ingredients but at least I'll know how much I'm off by...

I have a Mettler Toledo scale that does 1 mg to 2 kg very reliable!
This one was hard to find, but is an amazing scale!

My Keysight U1562A Passive Probe , 100:1, 300 MHz, 1.2 m arrived today - I think it will connect to the Hantek 2C42, which will be bonus.

A bit pricey for what you get, perhaps

but it should complete my basic scope probe requirements (spree), which was [to remind myself]:

a fixed 10:1 (100 MHz),
a fixed 100:1 (300 MHz),
two switched 10:1/1:1 (300 MHz),
an active differential switched 100:1/10:1 (DC to 25Mhz),
and an active switched 100A/10A current probe (2.5 MHz).

Haven't been around lately, who knows why, but I scanned the local craig's list and found a gem.  I've wanted an HP 70K MMS for ages, got pretty serious around the start of covid, again last February, and finally brought one home today.  I think this one was a steal at $1k.  I picked it up, brought it home and it seems nearly perfect.  Came with 70004 display, 70100A power meeter, 70310a Precision Frequency Reference for the time-nut in me, 70902A IF, 70900B local oscillator, 70908A RF Section and, drum roll....70300a tracking generator.  On top of all that I met a very interesting person that was running an inner-city center who had taken this and others as a donation.

Forgot to mention, he threw in some nice 'N' terminated cables, larger than LMR400 and a power sensor, 8482A.

Hope everyone is all well.

On the local craigslist I bought an "Isolating amplifier switch" from ELWE  model M35.
It seems to be an apparatus that can present 3 signals on one scope channel.

The switch arrived today. All in good working condition.

I'm a sucker for mechanical pencils and matching ballpoint pens:



Staedtler 925-25 and Staedtler 425-25

Bought a Rotring 600 pencil in 0.35mm a couple years ago. From what I remember, it was a japanese version, so got it from Japan. Outside of Japan, looks like the only version available is 0.5mm.
Pretty cool stuff.

Yup. Mostly outside of Japan/Korea/China/Hong Kong/Taiwan the min size is 0.5mm or 0.7mm.

In those countries, because of how they write the size goes to as low as 0.2mm (Pentel Orenz Nero is an example of such).

All brands sold in the west have always special editions in Japan of their products, or models exclusive to those countries (the Orenz Nero line up is Japan exclusive to the point that Pentel don't provide support in the west to those models).

We got a new Tek 2 series scope at work. IT is upset because it has Ethernet and USB ports and we didn't tell them about it. Oops.

No oops. It's not their business at all. You should require them to give you a local (non-IT related) Ethernet port at your PC, so you can use the new scope properly.

Every company has their own idiosyncrasies and, although I understand the nightmare of having an unknown "PC-like gadget" with doubtful update/upgrade policies, IT departments sometimes forget they are a support entity and not the core business of a company.

This is a case of "easier to ask for forgiveness than ask for permission..."

What I predict will happen is that management will get involved and make us do extra security training, but in the meantime I'm basically not allowed to use it.

I have to thank Douglas Self for writing this interesting book

Passive networks are also covered here, although they have many limitations.
But the point is that the topic of crossovers is more intricate than it seems and there is not much literature out there.

Today's delivery brought a cheap circular polarizer

seems to work ok
