40m of 2020 and 10m or 4020 T slot for the start of a 100W Laser build. Broke again...... 

[spongella]

Boonton 92AE RF millivoltmeter, complete with matched probes, for my test bench.  These were made in my home state of NJ.  Will be used for a few alignment projects - FRG-100 and Icom R7100.

Didn't "buy" anything, but paid $400 to get my tonsils out of my body after it gave me 8 years of chronic inflammation and lymph node pain, and costed me thousands of dollars on lymph node, liver, kidney and blood tests.

How do you feel after surgery?

My Six year old self still remembers the Icecream recovery diet after having mine taken out. As you are a bit older and recovery will take longer Gargle some Baijiu and add Icecream as needed

Quick 6101A1 fume extractor.

Since I added a room filter with an auto/sensor mode it's clear that y desktop smoke absorber isn't effective. Just five minutes of soldering with tacky flux and the room filter kicks into overdrive to clean the whole room.

I bought from Eleshop.eu who also made a great comparison page including video/audio of various brands/models at different settings https://eleshop.eu/knowledgebase/FAQsolderfumeextractors/

I had my tonsils out at 33.  I avoided too much pain through my Dr’s understanding that I had no interest in feeling any pain after the surgery.  I departed the hospital with a great big bag of the finest painkillers available to us mortals with a clear understanding that the drugs where to be administered by My wife and I was not to leave the couch.  I spent 10 days as a drooling potato living on iced tea mashed potato and gravy and ice cream. 

To be honest even after I came off the painkillers it was painful I would hate to think how painful it would have been if I was coherent

For DER DE 5000 owners :

 I did some conversion to Kelvin probes at mine instruments a few years ago. The best thing I could do to this instrument . It is so much comfortable than that a crocodiles.

I've finished my 3D model for printing your own probe attachments for the DER DE 5000. You can find the files (and some pictures) here: https://www.eevblog.com/forum/testgear/test-equipment-anonymous-(tea)-group-therapy-thread/msg2996692/#msg2996692

Terry01, Seems to be a very wise purchase, what better way to make sure you are keeping the proper "social distance" from people during this time!

Picked up a big ol' Dawn 6 inch vise, made in Australia!

I've been needing a vice for ages but I always go back and forth between buying quality used gear vs new cheap junk from the hardware store. I think I overpaid a little at 150 dollarydoos but it was local and I liked that it had the original paint on it...or what's left of it.  Brand new is around $483 so not great not terrible all things considered. Spare parts are available too but it just needs a clean and lube.

Can't wait to clean it up and finally use my new (old) Atlas Copco air compressor from 1989, a mate gave me a 3M spray gun so this will be fun.

Here, I'd probably pay like €35 for the initial appointment, and the rest is more or less free. Oh, and I can hand the receipt in to work for the initial appointment, and I'm reimbursed.

Hand cart for lugging boxes and storage tubs and such around.  Handles 200 kg payload in the horizontal configuration, 100 kg in the vertical.  Cost me only 35€ including shipping.

AMD EPYC 7551P (C32T64) for a new lab server cost me $450.

The prices are falling anda 2nd hand availability is increasing for EPYC previous generation.

So I am kind of forced to deal with CPU thermals on my upgraded Hackintosh: the i7-9700K is running at too high temperatures than I like: 50 deg C idle. So, a HuntKey S400 4U rackmount chassis, and a Thermaltake 120mm closed loop liquid CPU cooler.

Also I built a USB 2.0 switcher box, so I can switch back to my beloved Apple USB keyboard (pre-butterfly mechanism, the same thing on 2012 MacBook Pro and AFAIK 2019 16-inch MacBook Pro.) That thing is a bliss to type on.

The MacMini is connected to a 8+2 GbE+10GbE hub with VLAN, and the link is VLAN tagged to two sub-links, Internet and Ethernet. The Ethernet VLAN is then untagged by the hub and distributed throughout the internal network.

This is similar to how I do things. I don't have 10GbE at all, so I use 802.3ad link aggregate as the substitute. I have a repurposed used cash register motherboard acting as my router, linked to my main switch over a 2-way aggregated trunk. My Internet comes in as PPPoEoV (PPP over Ethernet over VLAN) from the ISP, then enters my home network using a second VLAN. That is in my wiring closet. My lab and equipment rack is in a separate room with its own rack top switch, linked to the wiring closet with a 8-way link aggregate. In the rack lies my NAS with its 4-way aggregated link, my daily driver Hackintosh and my HPC workstation

The only bit of shame is that Windows don't support simultaneous VLAN (unless you use a vendor tool like Intel's NIC toolbox), so I'm stuck with simple connection to the hub. This is not a problem since I do have a server to handle unsafe traffics, but if I want to use my own laptop as a server, I would not be able to do that.

You may want to explore the Windows PowerShell a little. Windows 10 Pro have those features, but it is tucked away in Windows PowerShell. (My HPC Workstation uses Windows 10 Pro for Workstations, which have a few more features like ReFS.)

AMD EPYC 7551P (C32T64) for a new lab server cost me $450.

How much is the motherboard? And how many RAM (and what type of RAM) do you have on it? This is reminding me of when I bought the pair of Xeon E5-2680 (v1, C2 stepping, Sandy Bridge, 8C/16T each, 16C/32T total) a few years ago for just US$150.

Unfortunatelly, full price for EPYCD8-2T that supports both 7002/7001 series. The memory is 100$ each for 32GB RLDIMM 2666 , still half of 8 slots to fill.

The MacMini is connected to a 8+2 GbE+10GbE hub with VLAN,

A. 10 Gig. Hub? 

That would be in violation of several IEEE standards. Don't you mean "switch?"

Here, I've got the next generation network under construction. Today, machineroom has a 7200VXR router, and a 4948 switch, all Cisco. Media cabinet has a 2960 24-port PoE switch; a similar but 10-port model sits in a linen closet upstairs. 5x 2702 access points supply wifi.

The next generation will swap 7200 and 4948 for a 4500-X router/switch, and replace one of the 2960s with a similar, but 10G-connected one. Just need to find out where I put those two 10G dual-port nics i bought, so file server (OpenAFS) and VM host (ESXI) can get connected.

That's a good way of killing a CPU fast...

Tell that to my 6 and 10 year old builds that still aren't complaining....

It's within spec. No different than what a CPU has to bear in pretty much every performance laptop (and it's usually not the CPU dying first on those).

It's probably fine for at least the 3 year warranty, you can always get the $20 Intel insurance if you're worried they will give you trouble for overclocking it (on a technicality most motherboards overclock by default and Intel may try and swindle you).

I wouldn't be able to sleep at night knowing the CPU is throttling not to mention the fan noise and power consumption. I'd just lower clock speeds by like 5% for the peace of mind.

I moved most of my proper office setup back to my home office for coronavirusmas, but didn't take my solder fume extractor (metcal BVX-201) because it's pretty big and setup in/through my office desk and seemed lile a bit too much effort.

I had my dyson air cleaner fan running in the room just for a bit of airflow, and it went crazy when I did some soldering. Nice to give the VOC sensor a bit of a test..  I got it during the fires so it's had a lot of chances to show that it's very good at sensing and removing PM2.5... now I've also seen it on VOC. ;-)

And now I'm reconsidering moving the fume extractor....

I'm on a NIM (Nuclear Instrumentation Module) binge!

Just received these; a dual logic pulse counter, and RS232 computer interface for it, and a single channel pulse height analyser (window discriminator).


I must admit, I have the same admiration for these modules that people has for aerospace/space electronics and parts. These modules are produced in fairly low volume, and

identical units has been used in most if not all famous high energy physics experiments since the mid-60's, from reactor monitoring to particle accelerators, diffraction studies, cosmic ray observatories, and so on.


I'm hoping to get some modules some day with 'famous' lab inventory labels, like Oak Ridge NL, Los Alamos, CERN, etc.

An oldie but goodie, an Icom IC-28A 2m transceiver. 25W, 21 memories, 3 of thechannels are for using tones but will be used mostly for simplex.  Good reviews on Eham.net. I like the older radios, easier to program. Will do a complete realignment when it arrives.

Denatured Alcohol  to mix up some Shellac. Also on the shelf next to it was some pure IPA in 125ml bottles but I still have enough for my 3DP and Electronics needs at this stage. Seems the panic buyers have their years supplies finally sorted
