I just got the last in stock ANENG smd tweezers for $6 from Banggood.  I have been wanting a pair so it was time.  There are a bunch of good reviews so we will see when it comes.
I got two sets of those, and both were horribly corroded at the tips. :-( After some thorough cleaning with contact spray and an old toothbrush they work halfways ok, though.

I actually use these SMD measuring tweezers quite a lot, anyone good a recommendation for GOOD ones?
Yes, if you're into SMD and/of lots of testing of discretes, get some proper Smart Tweezers.
I've had a pair of ST3 for years and they get more use than my DMM.

Some 50W LEDs in this nice format I hadn't seen before at this power.
  https://www.ebay.com/itm/50W-High-Power-COB-LED-Lamp-beads-White-Red-Green-Blue-with-60-degree-Lens/232590344184

Unfortunately there doesn't seem to be a reflector and external lens set suitable for these yet. Hopefully soon.

The lens dome on these appears spherical, is 22mm dia, and made of fairly rigid silicone.
All the lenses are clear, with the color-shifting phosphors in a thin layer over the LEDs. So of course the LED chip array is quite visible when running. At low power anyway, I don't expect looking at it directly at 50W would be possible without filters.
I haven't run them at full power yet.

Much like the 50W square LEDs, I bet the red ones can't actually take 50W and will burn the phosphor if you try.

cool

It looks like they used to be a glass lens, and now the "upgraded" models have silicone lens: https://www.aliexpress.com/item/LED-Glass-lens-COB-Chip-Lamp-20W-30W-50W-LED-Chip-28-32V-Input-DIY-for/32800893666.html

I have one of those from Banggood, their not the best around but they do a reasonable enough job, lust make sure that the solder joint is clean enough before testing if doing it in circuit as any flux residue etc will result in extra pressure being applied and then the contact tips get bent.

Thanks for the advice on that.  I don't know how often I will use it but for the price it should suffice.

I find the two hand probe method work much faster and better, perhaps if you are used to eat with chopsticks the tweezers will feel more familiar in use (no offence intended just an objective remark).

Funny enough, I am used to eating with chopsticks. ;D  I also have a DER EE DE-5000 that has the same style tweezers, just a better quality.  I have used them and they aren't so bad to use.

these aneng probes are really bad quality when you hold them. you don't know what you're measuring. but they are cheap. your choice...
the tweezers that are with the deree de5000 are of really much better quality.

Hmm, it also exhibits another unwanted behavior if strict observance of the instructions aren't followed. It will if applied to liberally become like solder mask and nothing will stick. From that it's a very fine line to the point where the user/operator looses total control for a number hours. [emoji1787]

Four Huber Suhner Minibend-12 precision SMA cables. Rated to 24 GHz but I tested them to 26.5 and they look good. So nice to have flexible test cables that also perform quite well and don't stress the connectors at all. I believe Shahriar uses a variation of these in several Signal Path videos.

Nothing like "cable or connector porn"!
I want an sma depth guide/guage, I have the 'medium' strength sma torque wrench.
One of my bits of crazy gear is a noise source - it actually comes with a 3.5mm connector (a posh sma really) - first thing was to put a really good adapter on it - so I didn't muck it up!
Whoah! Watch where that landed we might need it later.

Yep, my 3.5mm stuff only comes out on special occasions, the other days I make do with SMA :)

That's one way to refer to it I guess... I prefer fuzzy logic generator instead.  :o  :-DD And my go-to is Balvenie 12yr. as a minimum (thanks dad  |O).

To each their own of course, and enjoy.  :-+

My shack is at risk of becoming Alcoholic. Current selection Dimple 12yo, Hendricks and a fresh bottle of Glenfiddich 12yo waiting not to mention Beer, Red's various and an open bottle of Port  :-DD

Anyone got a spare liver?

@beanflying - if those bottles are still waiting - I can assure you that you are no alcoholic! They are to be enjoyed, carefully!

I feel so ghetto.  My favorite tasty beverage is a shot of Grey Goose out of the freezer.  A very rare shot between the diabetes and minor cirrhosis of  the liver(not due to alcohol).  That means you can't have my liver.  Even with fava beans. :popcorn:  I also enjoy an occasional beer, not the 'murican piss water called beer, more of some of the local microbrews.  Oh, and the even more occasional Sake with sushi.  I am definitely a light weight.  I stopped the self abuse in my 20's before I could tip over into alcoholism.

Freshly delivered from eBay: a power supply, a diode, and a 6.5 digit KVD. Unfortunately, I can't find any information on the model, "PPM  412", with 1V and 10 V ranges, built in 1981. The board has points labeled 100V and 1000V, so I figure there were other higher voltage models. The left shield contains the zener reference (it appears to be ovenized), while the right has the upper ranges of the KVD (with dozens of trim-pots). The output Cliff-brand binding posts were broken in transit (will be replaced with parts on hand, but eventually some Pomona 3770). Once I get it working, I'll post more photos.

Well spotted - it is an old HP boot which fits the K2400 quite well. It makes the the unit fit in much nicer with the other gear, and as an added bonus it drives TiN nuts.

I believe you outdid me on scoring one of those, Steve. Nice catch!

It does indeed fit well. Perhaps I shall do that with my K2700.

Also of note is that bumper will fit on the HP 3468B and 3478A DMMs. I think it may fit the E361xA power supplies you have there.

I just needed a few funny sizes capacitors for a repair project so went over and got them from the new Altronics store at Airport West which I had mentioned a while back in another thread. They are going to organise and post me out a trade card which works out to be a substantial discount off their regular prices, they even gave me the capacitors at the lower price which was pretty good really considering I haven't dealt with them for quite a while. They also had a very nice looking illuminated magnifier on special which I didn't get and now regret, I might have to go back later on this week for one. I have no affiliation with Altronics whatsoever and am just a regular trade customer.

The display really is something else! It's beautiful!  I'd like to mess about with some of those bulbs but it's quite dangerous if you don't know exactly what your doing right? They need high voltage?
