Well some flavour (Kelvin, Varley, Murray etc.) of bridge configuration... or a Potentiometer - it just has to be one of those!

The small info sheet mentions Varley and Murray...
The box is now drying, I needed to bath it to get all the battery crystals away. Propably first service in a few decades.
Yes!
Hope you manage to restore it successfully.
Hmm... What this might be?
L&N wheatstone bridge, I recognize the switches. Most likely it is a test set.
I bought a new router. The
MikroTik RB962UiGS-5HacT2HnT. I was sick of all the consumer shit not getting any updates and not having basic features, like setting your own DNS on the DHCP server.

This router runs the most sophisticated software I have seen so far: RouterOS.
Steep learning curve, I'm sure, but I'll learn.
I actually ordered two more hAP ac lite to play around with.

You can do lots of stuff from Winbox... Good place to start to get a feeling what is there..
I know. It's running for a while now. WiFi performance and coverage is really good.
I played around with the other for a bit, and had a few scenarios running pretty quickly:
- Dual radio WiFi bridge 5 GHz uplink, 2.4 Ghz Access-point.
- Selective VPN gateway, only a few selected clients will use the VPN as gateway, not all of them.
- Equal bandwidth sharing using queues.
Todo:
- Site-to-Site VPN, to use the same WAN IP and network in second house. (for server and iptv)
- Layer 2 Wireless bridge, for isp proprietary iptv boxes.
Unlimited possibilities! 10/10 would recommend. (if you know your OSI)

wow!!
now I know what router I want for my new office!

I use a PC engines
APU running Centos but the RouterBoard stuff looks very interesting.

Same here. APU2C4 running pfSense. And another one running Mail-in-a-box as a private mail- and cloud server. Very satisfied with both
Tin,
You are going to repair it, right?
Those universal sources look nice. I'd like to have one too for no good reason other than that they might be useful some day.
Those are still rather expensive, where is that grocery store of yours?
Got this from the local small ads today
Voltcraft Dosimeter - Radiometer (re-branded Russian made RKSB 104)
Overall it seems to be in good shape, fully working, including the original case and manual.
Hopefully I can dig up an old contact to check how far of the calibration is.
The device can measure the dose equivalent rate of gamma and beta particles in µSv/h. There are two measuring periods to select from (27-29 seconds and 270-280 seconds). The longer period is for more accurate readings. Besides the measuring mode there is also a surveillance mode with configurable alert threshold.
Since I did not find any information on the device here on the forums, expect tear down pictures and some more in-depth information coming soon
Edit: I posted the name in cyrillic unicode, but the forum software can not handle that - very disappointing. Did recognize the lack of supported chars before (accents et.al.). meh
Just got these and maybe soon a HP 3466A bench meter.
Got this HP 3562A DSA from a university as "surplus" in unknown condition.
had a bit of a rough shipment but, its built like a brick shit house and survived with only a slight dent..
1 lithium battery and one tantalum cap later its up and running.
looking at the chip date codes, it looks to be about 28 years old and looks like no ones been inside it before.
here it is doing a noise floor test on a mic preamp.
Tin,
You are going to repair it, right?
At least, that's the idea...
MasterTechMhm, voltnut's approval was not wasted
Now get two LTZs in those boys and off you go...
nctnico3245A's are hidden gem of the voltnuttery. Mine saved me during tests/calibration checks many times. With LTZ pimp-up it's also very stable mid-term DCV source (<1ppm over 24hours easy). High AC resolution makes it handy for many of AC checks.
1:10 amp only sweetens the candy, however MasterTech got dual-channel versions instead.
Here's quick example how 3245A can help to get lower noise resistance measurement together with 3458A, measuring 10Kohm. 3458A red line is regular direct connected 10Kohm, about 3 times noisier.
Innkeeper, That's a great looking machine !
looks like no ones been inside it before
So show us the inside! That's the best part.
I started to take a video of the insides as i was repairing it. if there is really intrest, i'll finish that up and post.

If there is really interest? This is EEVblog! If there was any more interest we'd be in finance.

Yes of course there plenty of interest, I cant wait to see it.
