Have been using pill boxes for storing and picking SMT components but found these on LCSC and just had to have them

I might be missing something, but how does the PCIe expansion fit? I mean, I can see there is a PCIe socket on the side, but all the cards that might fit look like normal PC cards with fittings for the case. But the Zimbaboard doesn't appear to have any way of securing a card, so it is hanging there in the breeze. Couldn't fine any cases or anything to solve that either - have I missed something or is it expected that this is just a dodgy don't breath on it hack?

Swiss army knife, not chef's knife.

People 3D print brackets and the like.  In my case it's very likely to end up in a corner collecting dust and not be bothered.

However.  I do agree.  If you were to, say, knock this off the bench onto the floor, it will almost certainly snap the PCIe card AND destroy the socket, if it doesn't short the PCIe bus out and fry it.

EDIT: The way I looked at it.  It's basically a near like for like replacement for a Dell Optilpex eWaste recon box.  Except it's half the size, half the power and twice the number of NICs.

Still think they should put 2xm.2 slots on the back of it and stop teh SATA ports for the next version.  Assuming the pissy little CPU can actually shift data.  That remains to be tested.

OK, thanks. I could find a use for it as it is, I reckon, but the PCIe connector just plays with my mind. Surprised they didn't make a backplane card of some sort to allow this kind of expansion whilst adding decent mechanical support too.

SH72 soldering iron, I don't know why it's so underrated here on eevblog but after some use, I think it has really good value for the money (for beginners).
I bought it on AliExpress for 17€ shipped and if you search you can buy spare tips for just 3€ (They are a bit light, but they are ok for small stuff).

The tips are not the shortest (quite the contrary), but I have no problem with that. You should go with the BC2 tip: it has a flat head that permit good heat transfer and it’s good for soldering SMD.

12-24V power up to 60W. I use it at 12V, and I can solder THT connectors fine. It gets power via a barrel jack, but I removed it in favor of a nice flexible cable.

I'll let you know how it goes when it arrives.

If you can up the budget by $8, ksger C210 for $25: https://www.aliexpress.com/item/1005005519807256.html Performance and ergonomics will blow you away.
Mostly small size tips though, more for SMD.

First thing that popped out at me with that Ksger was "12V 5A" and "70W". No doubt doesn't affect functionality, though :)

The current I see at 12V is 4.5A so 54W. You can raise the input voltage up to 20V and you'll easily hit that 70W figure (as its a resistive heating element).
But... the C210 tip from JBC is rated for ~20-25W?, so you're already massively overdriving the tip at that point. There are settings for current limiting in the menu, though they don't seem to work that well and there is no manual to explain them.

Went thrifting today, found a pleasantly plump old DC power supply, looks like 1970s vintage, a chunky black box with two meter movements.
A Zurich (I know the city but not the company!) DPS-712M
But they still make em, looks like.
http://www.zurich-electric.com.tw/zu-p01.html

Didn't really need it, but it has speaker terminals for output which might be handy for bare wires, and for running my LiPO charger.
25$ but hey, no shipping and this thing's heavy!
Also thrift stores charge more these days.

smooth brass shaft extensions for any miniature tuning capacitor or gangs used in most analog AM/FM transistor radios of the 80s.
with this brass shaft extension any 6.5mm smooth shaft knob can be used with it.
sold in packs of 10 brass extensions with 2mm mounting screws.

I don't suppose I'll build an eez bb3? ... but I have ordered an Arduino Due  :-DD

edited to add link - the Due is not used in an eez bb3, but it was in its predecessor eez h24005

I got this Agilent 34401A, maybe not the best price but in really good condition, I still need to to check it. Looks like was barely used. My first 6 1/2 digits multimeter. I might open it and check the statua of the elec caps and general inspection. Old tool but very excited about it! The VFD is in perfect condition which is also important.

My first Fnirsi:

It is a USB power analyser with USB-A and USB-C connectors. Not the cheapest one but it can also read e-marker information from a cable.

cheap glazed ceramic insulators
in sets of 5 pieces.  available in 4 colors.
I add the dimensions.
the intended use of the chinese insulators is to hold mains voltage wire
as in 1930s vintage style house electrical wiring.
somewhere in the back of nowhere this is the electrical code.
just in case anyone is interested.

The hard part is always figuring out how to cut the X in them before cooking though. Unless you like to blow things up.

I'm continuing my Green Hoarding* !!
Today I found two things that ticked all these requirements
Ugly √
Heavy √
Old √
Clunky √

One could be useful, the other not. But both get a home in my junk!

* Green Hoarding is hoarding without shipping, in local thrift stores, thereby reducing my carbon footprint! Which makes me feel better!

Bought a SDM3045X "coersed" by the 10% Siglent discount until the end of the month, and an extra Marco Reps 5% discount at Welectron.

I guess I have to thank Rigol also  ::)

The DMM came with firmware version 5.02.01.09R2

EDIT: the latest firmware available to download that I'm aware of is V5.01.01.09R2 (Release Date 04.27.23 )
Calibration date: 2023-05-31
