Soldering pincers with interchangeable quartz points. Will be interesting to see the benefits. Did anyone reading this work with these in the past? They were made for dental applications, but sometimes tools from other disciplines can be quite helpful. I think a melting temperature >1700°C is beneficial, when you are soldering at high temperatures with flames, what we typically avoid when soldering components onto PCBs.  :)

My video endoscope had a broken display, when I took it out the box which I stored in the cupboard after using it the time before. Maybe the camera pressed onto the foil in front of the display, when it was in its box. However, I decided to buy a replacement 5.5mm endoscope and the new one has a second camera looking to the side and a better image quality.

Is it a second camera or just a smart placed mirror?

Manufacturer calls it "Dual Camera" and I think that is true. I can see two lenses and I guess the sensors are cheap enough to not share them. The endoscope units without display are rather cheap (about 10€). The "dual camera screen endoscope" is approx. 50€.

Have you a link to where you bought it?

I thought glass is not ESD safe lol, they charge up glass rods IIRC. Rub a textile furthing on a glass rod or a plastic rod and it holds a charge.

Kind of wonder about ceramic tweezers too, I bet they should be made out of nitride or something conductive

I visited a craftsman's workshop and was introduced to his master
And brought home a wonderful handmade 700cx25 steel fork weighing only 600g!


(Sujami-Bressan steel fork, to be chromed)

Usually, a steel fork is 900-1000g, this one is special as it's as light as aluminum but much stronger!

cost:
  • Industrial chromed steel fork: 50 euro, 1000g
  • by a craftsman handmade chromed steel, 300 euro, 700g
  • by a master craftsman handmade chromed steel, 500 euro, 600g


Better than Vetta's, better than Columbus's
my Sujami-Bressan chromed fork is the Hattori Hanzo of every steel forks  8)

3d printer nozzle with a polycrystalline diamond insert. Because why not?

Harder than any abrasive filament, and PC diamond has better thermal conductivity than copper. Supposed to be low friction too.

Thanks for that.
I might try one.
My carbon fibre reinforced PETG eats nozzles.
They are pretty expensive though.
If it lasts longer than 4 of my hardened steel ones, then it will be worth it.

qty=2, Raidon RAID box, s/ATA disks, SCSI U320 interface
qty=10, Seagate Barracuda disks, (8 to use, 4 on each RAID box, two spare)
qty=1, IKEA metal shelving, to be used to accommodate the two RAID units

despite they are Hardware RAID{0,1,5}, you can switch to "bow-mode", this way on the interface you just see four disks, so you can use software kernel RAID functions.

A set of analog meters

me too, 16 minutes ago  :D

two analog amperometers, 0-6A (rare to find), in white plastic, to be mounted on a panel.

do you know if there is a way/kit to backlight this kind of meter?

I need to install one of them inside a box, so if backlighted it would make it more easy to read  :-//

A whole lotta screws for my HP4145A and 7225B Plotter. The former is missing some and the latter needs new ones as someone once upon a time managed to bend nearly all 4-40 UNC ones on it.

SUB-D 25pin Connectors and symetrical cable. To convert the Centronics 24pin interconnect cable between the 4145A and its Test Fixture to SUB-D. Trying to convert a HP-IB cable to straight Centronics 24pin proved to be just a headache.

TWO Network Analyzers. Wandel&Goltermann SNA-62. One functioning fine and the other with seemingly several problems. Local Oscillator doesn't seem to swing and some brain rot. Might be BootRom, RAM or some other digital problem. The functioning one will repair the other one after using it as an Troubleshooting aide.
A project for the Winter though. After cleaning and inspecting the functioning one.
Need to get a Operator Manual for it too.

HP3577A Operators Manual. It was cheap and available. A picture book for grown ups essentially. And a sad reminder how great Manuals once were in decades past.

Don't know, but you can always add a light on its own battery.
