The locator is IO76hn, it looks beautiful from the pictures I've seen and the weather here is glorious at the moment though I think I'm going to a vat of midge repellant.

I *think* I might be able to string up 30-40M of wire and as we're right on the edge of the loch I should be able to get a decent earth as well.

A Logitech Unifying receiver just came today (B072JW9LT8). Duh, Amazon shipped the wrong one.
Doesn't the unifying bit mean it doesn't matter? Or are you trying to fit it flush into something?

Recognising the need to be at the forefront of modern digital technology I took the plunge and have acquired a 'scope to meet my needs.

The seller assures me it works but may need some TLC to get it back to optimum performance

Neat little scope. Haven't seen one of those before.

So, the digital part is what, the power switch (on/off)?  ;D

Brill? Short for brilliance, meaning brightness? I doubt it has anything to do with the fish.

I started out with a ex mod Tektronix 654b many moons ago - you had to leave it on for 30-40 mins to warm up



I need to replace  my scope soon but budget is a issue (must be new)

Vintage pretties! 2x Galvanometer (from what I've been able to find +-20uA, will check later) with two built in switch contacts! The basis for a vintage regulator.

Anyone know what this is?

Full res + more pics:
https://imgur.com/gallery/jRAOLyf

It has a 3-pin DIN in a 180° DIN5 arrangement and a blower with what look like TRRS contacts on the output tube. The cable is coiled and the housing is all metal. I’ve never seen one like it but could it be from a hot air station?

The TRRS contacts remind me of JBC style soldering iron tips so I hope no one is trying to do the same thing with hot air by building the heating elements into nozzles! It doesn’t make sense where nothing contacts it to directly sink heat.

So... anyone recognize this?

OK, it looks like the cable unplugs when you remove the back cover. Still haven’t been able to remove any screws to go deeper. Not sure what the adjustment it for.

A vape of some kind was my first thought too but the cable tying it to something else doesn't make sense for that kind of portable device. It’s definitely got a blower of some kind in there.

A $10 digital tachometer.

This tachometer works good. And, it's only $10.

I need to check the governor speed of my lawn mower engine. I decided to test the tachometer and verify it's accuracy.

First was the shaft speed of a four pole induction motor. 1780 RPM. That's reasonable. I then connected an LED to my waveform synthesizer and set it for 12345 RPM (205.75 Hz). You can see from the picture that it's right on.  My mower engine max speed is 3600 RPM. This tachometer should have no problem with that.

A Tektronix 422 'mini' oscilloscope. SN 101234
Bought for the princely sum of six carbon rods. WW2 searchlight carbon rods, so actually rather precious. They went to a good home.

Now I need:
 * The front panel grounding post knurled nut, missing.
 * Two black knobs for the vertical beam position pots. (someone had replaced them with non-original knobs.)
 * CRT protection plastic sheet. Missing.
 * The internal battery metalwork frame. Missing.  But I can make a replacement.
 * Service manual. Original print, not pdf.
 * Maybe the power cord, which has a very odd AC + DC 6 pin connector to the scope. But I think I will replace that with an IEC
   for mains, and a separate connector for DC power.

Plus get it going. Reported to be "Used to work, didn't last time he tried it."

Edit: The Cal-out point is at -2V DC. Looking at the schematics (from tek-wiki) that strongly suggests the -12V rail is dead, but the main switching reg is OK. Good.

I happen to have a couple of 80MB SCSI-1 drives that were still spinning a few years ago when I powered them on. Hopefully they are still alive.

I have one of these. I made a video on it too. They seem to work ok.

As for my latest purchases, I got me a Hakko FM-206 rework station and an Amscope stereo microscope. (Trying to figure out how to attach a Raspberry Pi camera to it...)
I really gotta tidy my bench.......

I tore down two Logitech USB webcams, and found out you can make "eyeballs" out of them, as the board is about 10-12mm behind the lens.  Of course, the resolution wasn't too good. However, IVPort Dual V2 and two 8Mpix camera modules, sounds even better. Good luck! If you get it working, do post some images.
