Thank you for the links. Unfortunately, none of them deliver to India. The problem stems from the sheer number of sellers who can't ship to my country due to the pandemic. Hopefully, 2021 would be kinder on us.

Circuit Specialists soldering iron - a treat from some spare cash lumbering in Paypal... I recently moved all my test gear in from the workshop due to humidity and this iron is more 'shack / study i.e. little bedroom' friendly than my reflow station, and it's blue!

Best for the gentle removal of internal flux.

A mains cable for my -hp- 400H (Valve AC volt meter made for Europe in then Western Germany, so better connector than that little oval shite they had from the US before everybody went IEC C14).



Finally, I could check it out, and yes, it needs work, but all ranges are there, the movement is free and all valves work.

It does a good job of cleaning out the old cobwebs on your internals, that's for sure ;)

Just a bunch of odds and sods that I have been missing for a while: some RG-174, soldering sponges, Y2 caps, switches and a few 0805 R's to help fill out the inventory binder.  I had to place an order for a single $15 chip with DK anyway having smoked the only one I had for my current project.  But SWMBO can't resist getting free shipping so it had to be expanded to $100.   ;D

The original inspiration for the buy?? An AD9833 DDS chip here...

An early '70s VTVM, the RetexKit VV-1. In fact a clone of the HeathKit V7-A or EM-11E (E for Export).

It was sold as a kit in Spain under license from HeathKit. It is in very good external condition albeit with no probes. I had to make one for DC out of a malfunctioning chinese oscilloscope probe. Some resistors have drifted in value and I'm replacing them to get accuracy in all scales. Also had to tame a bit the power supply circuit as it was designed for 125V / 220V. There's nearly 240V at home and plate voltages are out of spec. I'm having a lot of fun restoring this thing...


[EDIT]: corrected typo.

Current sensing transformer, some LM60440DKPR DC-DC chips, various capacitors and resistors needed for the LMs, BNC connectors, RJ45 connectors, Raspberry Pi heatsinks and 30mm fans, roughly 15M of desoldering braid (was really cheap)

Just ordered this one:
https://pine64.com/product-category/soldering-irons/?v=fa6c6ebcea6a

yup I really needed another soldering iron  :-\
But although it might end up being crap, looks quite interesting, and it's quite cheap...

A Mikrotik RBM33G RouterBOARD, and a two 1.54" IPS panel 240x240 display modules (with a PCB instead of a FFC/FPC cable) from EastRising/BuyDisplay.com.
The RBM33G will be a 4G/LTE router/firewall running OpenWRT, and one of the display modules a small status display for it, hopefully.  (I'll need to write userspace support from scratch.  Note that although the pins are marked SDA/SCL, it uses the typical 4-wire SPI: clock, data, chip select, and command/data.)



I forgot all my serial adapters have TTL level outputs instead of RS-232, so now I'm waiting for my adapter to arrive how much work it is to add the status display; whether the GPIO pins are sufficiently supported by the Linux kernel, or if I have to use a microcontroller in between.

The two top left board sockets on the RBM33G are USB-based mini-PCIe slots for WWAN modems; I'll be using a Huawei ME909s-120.  The one top right is a M.2 NVMe 2242 slot for a PCIe-based SSD, next to an USB 3.0 socket.  On the bottom, you can see the RS-232 serial port and three gigabit ethernet connectors.  I've ordered a Kioxia BG4 128GB 2230 SSD (removed unused from a Dell laptop) as they're known to work with this board, and it was cheap enough; I like to play with this kind of hardware, so I think it'll be useful for me.  An SSD is completely unnecessary for normal router/firewall use; it has 16MiB flash for an OS built-in, and a smaller separate flash for a bootloader.  And 256MiB of RAM, so OpenWRT should run just fine on it.

(Simply put, I got fed up with crappy USB-WWAN adapters, and wanted something really designed for this kind of use.  The USB adapters only have a DC-DC converter from USB 5V to 3.8V, and some passive decoupling capacitors, but even so, the ones I can find are just.. not something I can rely on.  An LDO generates too much heat.  I'm not an EE, and don't trust myself enough to design the board layout using TI TLV62569DBVR buck controller, because of the switchmode EMI, although it'd be near perfect for this use case otherwise.)

Meiji EMZ-8TR microscope with 2.5X camera adapter for my Nikon FX DSLR. Replacement upgrade for my Eakins trinocular microscope head. Hope it's as good as I expect! New from TEquipment.net for the lifetime warranty.

Sometimes I think you're just hording them. Other times I suspect you might be taking them out to the back room and touching them inappropriately.

Some of that might happen.  :-X

But no, 28 in one order is the biggest thus far however just keeping reasonable stock levels is a right PITA ATM.
At one time I could get a few in by air to carry us over until a sea shipment arrives (1 week vs 1 month) but even by sea is troublesome these days as the vast majority of world freight now comes by sea until we get this CV thing under control and return to some resemblance of the way things were just a year ago.

Yeah for a guy with a love of TE it's a pretty nice business to be in.  ;D

The wife just takes a look at me unpacking orders with a grin in my face, rolls eyes and goes does off to do some sewing, gardening, housework or anything to keep her in touch with reality while I'm in this other world.  :-DD

I can beat that: My wife helps me do detailed reviews of PCB artwork. We have an associate who does the layout, then I review the artwork trace by trace while she handles the schematic. She knows almost all schematic symbols now, and requires almost zero hand-holding. She marks what she's covered with a highlighter and has caught many an error. Our PCB guy now asks if SHE has signed off on a given board design, rather than me. I definitely married the right girl!

Right.....until her fascination in your hobby wears off.  ;)

Nearly 40 years ago as newlyweds I remember populating a stereo preamp kit so we could play our teenage acquired records on our old valve stereo system that wouldn't support a magnetic pickup. Her, armed with a resistor color chart and a component chart would pass me each component as I called out the R1/C2 whatever and after some time she got pretty fast at recognising values correctly......but now it's 'buy one already made and tested' !   :horse:

We've been married 40 years so she's had ample time to back away. Fortunately, she recognizes it's part of my profession and our income stream so she's very supportive. She also handles the accounting, taxes, etc. of our company so it's all just part of our environment.

She's picked up an impressive amount of technology in the past four decades. Early in our marriage when she got her degree, she was required to take a technology class of some sort. This was back in the 80's when PC's were "the new cool thing" at home and in the workplace. The professor started talking to the class about "RIOS". She bit her tongue but finally couldn't take it any more, raised her hand, and asked "What does RIOS stand for?" His answer: "Random Input/Output System". She could not let that go, and corrected him in front of the class. He replied with certainty that he was correct, and she countered with "My husband is an Engineer, and several of our friends are Engineers at HP [one of their T&M divisions used to be located here so he would have known about them], and I'll be happy to have them come to class to discuss it." She told me this the evening of the day it happened, and I told her to prepare for an F in that class!

Fortunately, the professor was a stand-up guy. He did his own research, owned up to his mistake in class, and they went forward on good terms. She got an A too.

I hear what you're saying, but at this point I think she's fully integrated (perhaps "resigned" is a better term?) into the architecture of our marriage. I'm not concerned. Yet.

While on biz travel, out of town, spotted a local black smith at the town I visited, and ended up brought home a short sharp thingy.  :P

No, its not the elite high quality Japanese sword, but from little chit chat with the creator, he honestly admitted its from car's spring steel, once forged, its properly hardened (like properly quenched and etc) and also it was properly through 1 full day of tempering at exact temperature (if I'm not mistaken  ::) ), and let it cooled slowly for few days, then did the finishing like sharpening and polishing with minimal temperature increase, and finally encased in hard Indian rosewood. I trust him after took a short tour around his workshop, it was fun.  :-+

PS : Yep, it slices thru paper easily.
