Received today - a decade capacitance box to match the resistance box I scored a few weeks ago :)
They are really nice.
I have of of them and in addition the same size box for low resistance.
There are 3 kinds of people in this world, those who can count and those who can not.

Well, asides looking at the paypal notifications on the phone this morning and groaning, it didn't go that badly.

I bought a DPH5005 boost/buck PSU and case for £50.  It started when I decided I could run my bench on solar power, but my only DC input PSU is a buck coverter and won't produce 12V from a 12V input.  The beer got to thinking and... we'll see what it's like and how much smoke it releases in a few weeks.

I bought the DPS5015 with comms, then realised I need a higher rated input for it so bought one of these: http://www.ebay.co.uk/itm/192325585960  -but there's no way it's going to supply 800w for longer than a millisecond before it turns to glowing slag...

Video the load test.

My take on this is a bit "belt and braces".  I don't need a 50V power supply.  I might need 24V tops.  But if I buy a cheap 24V power supply I might need to run it at 100% rating and be disappointed when it doesn't meet it's specs or go kapoof in a white cloud trying. 

So I buy a larger supply than I need, so it runs gently.

I have the DPS5020.  I have not attempted to pull 1000W through it and nor do I intend to, EVER.  I have pulled 20A through it for a few minutes, but got a bit scared and backed it off.  Scared for the PSU and the LiPo it was charging.  4C charge is a bit too dodgy for me, though a lot of people do it in the field.

I went for a 48V 10A LED lighting brick for the DPS.  If you can live with lower voltage LCD Monitors and TVs are now going "external" DC bricks with some impressive ratings.  My monitor has a 24V 8A brick for example.  Gotta be some on the second hand market already.

Bought today some Wiha screwdrivers (Picofinish set) for slotted screws, vice-grip wrenches and a 6mm flat-spanner from WGB.

Awww..  Those baby vise grips are sooo cute!  If you feed them, will the get bigger?   :-*

Seriously, I don't think I've EVER seen them that small!  Very cool.

I got this rather lovely microscope delivered this morning. I'd been looking at getting another to replace my first foray into microscope which was an Andonstar A1 which was reasonable but suffered from too much free play and a breeze would blow of focal point, so I started to think about the Andonstar V160 which featured a more robust design of up stand pillar to help remove the free play. Then I watched a review by TheDefpom

That looks cool - from Banggood? I ordered one a few weeks ago and rather expected delivery by now. China post can be so frustrating sometimes!

You should post some captured images in full res (if the filesize makes this possible). :)

No, I got mine from AliExpress, it will take stills VGA, 2M and 5M but the 5M on the microscope itself takes an absolute age to process and save but that might be a function of the SD card, I'll have get a class 10 and try it. You can also plug it into the computer and with some suitable software via the live image on the monitor. The software (not supplied) will take snapshots, the following are taken on the computer with the lens about 9cm away from the PCB.

Tomorrow I'll take some snaps on the SD card and compare /post them here.

That seems very interesting and for around $60 delivered it seems quite cheap too.

Pre-ordered an I-Extruder, been out of stock for a while, and it's finally open to another batch of back order. Will ship on 26th, so if you want one, grab one before the stock depletes again.
The EFD in our lab never work well. It has a leaky glass gas regulator (actually a water vapor remover) and thanks to bureaucracy, no one fixes this explosion hazard.

I bought a new project for my 'spare' time from the antique radio museum where I volunteer.





It's an RCA Model 143, introduced in 1934.  The cabinet is a bit rough (understatement of the year there..), and it will need to be recapped, but I think it's a pretty cool looking Art Deco-ish piece, and has some nice potential.  All I need to do is learn to veneer, and fabricate the missing cabinet trim bits.   :-DD

Lab Cat, of course, was keen to get going on it immediately.


And wasted no time before beginning his examination of the chassis.

I would say for $120, I'm totally not impressed. I expect to see proper chamfered edges and thick anodized aluminum or tool grade steel. Colorless type III would be acceptable, but thin type II is not.



No, not impressive for that price.

I have to say, I was impressed with my recent purchase of this 2 1/2 " precision toolmakers vise. They can be had for $60 on eBay.  Appears to be good quality tool grade steel and square. Smooth with no significant slop or backlash.   Not high end for sure but for the money  :-+

Now for some shots taken from the microscope screen direct to SD card in 2M size.


2N2222 transistor at 130mm away.



Same transistor at 30mm away



Small thermister at 130mm away



Same thermistor at 35mm away



Same thermistor at 30mm away

Pretty impressive piece of kit, its weakness is the lighting, needs a ring light to take advantage of its abilities with out suffering from reflected light entering the lens and spoiling the image.

Anyone know of a ring LED light that will fit onto a 33mm dia barrel?

Yeah, I thought it was pretty cool looking, so I made a donation and it followed me home.  Have no fear though - its place in line is somewhere BEHIND the long suffering HP 5340A.   ;)

Produces clear images, and I think you're right about the lighting being an issue - more because of reflections than anything else. I've already decided to add a polarising filter to the end of mine, I've got a 38mm dia one lying around somewhere to try. With that fitted it should be possible to knock down the worst of the blown highlights which are inevitable with a bright light source and shiny pins etc.

Hello Pat,

Awww..  Those baby vise grips are sooo cute!  If you feed them, will the get bigger?   :-*

Seriously, I don't think I've EVER seen them that small!  Very cool.

I've bought them at Hornbach (building centre in Germany https://www.hornbach.de/ ) for EUR 2,50 each incl. VAT
This is the vice grip: https://www.hornbach.de/shop/Mini-Gripzange-110-mm/8397016/artikel.html and the quality
convinced me nearly immediatly (heavy and solid construction) so I bought three of them.

I found it on Amazon at a sensible price in half a dozen designer colors.
