26C here today.  :P

Got your meds Med ?
Good luck buddy, hunker down and keep warm......where's your good lady ?  ;D

Yep, picked up the meds yesterday. The only thing that really concerns me about this potential storm is the ice. If it accumulates to any extent on the trees and the wind kicks up as predicted it's gonna be a mess. And all our power is overhead and you know the result.  :palm: :scared:

The lady is on duty this weekend so she's at home base in NYC. Currently the weather down there is a winter storm watch only. So it will just be me, myself, and I to keep warm.  :-DD

You can use the Corona to wash the window. That's about all it's good for.  :P :P :P :P :-DD

Casually enjoying a late night pulled pork sandwich and beer, until I found this beauty lodged in the roof of my mouth. Maybe my lady is telling me to quit staying up so late.

I would have loved to send you some of the heat wave we had here last week, three days with the daily maximum 40-42C, the minimum never got below 23C.
Our prayers were answered in that the airconditioner didn't break down!
Whoah! Watch where that landed we might need it later.

Last of the Freebie Vintage bits from 'the box'.

Vintage Hirschmann Test Clips (4mm with grub screw) and 5 pairs of 'German' but otherwise unbranded 4mm pins for bare wire with spring loaded clamps. Not sure if the plugs were ever used on any meters but might suit a vintage resto for someone.

Still a few bits left from the earlier photos if anyone is keen.

Woohoo actually bought some test gear. MFJ-259B antenna analyser.

Does a whole variety of stuff including acting as an L/C meter

Nice unit. Lots of bells and whistles.  :-+

The Fluke 8810A that I won on Ebay finally got out of Texas and is at a UPS hub in Rochester, NY. Next stop would be my local office in Kingston then delivered. But I doubt it will move out of Rochester today with the storm prediction. Hopefully I'll have it Monday.

I just got sucked into a job that required the purchase of a 3 ton chainfalls. Pray for me.

eBay. Been lurking for a reasonably priced one for about six months.

It replaces my current antenna analyser which involves dragging a pile of kit into the garden :)

-23 here  :o

Right now it's 0 C here but after the storm blows through it will get almost as cold as you.  :scared:

I remember when I used to do the "snowbird" thing, full-timing it in a 33-foot Georgie Boy. We'd stay in the Finger Lakes until the weather got cold enough for fairie rings around the full moon; then pull up stakes & leave. Several times we left just in time to see the first ice storm of the season; the valley was always so beautiful... and so quiet you could hear the snowfall. Literally like something off a Hallmark card.

Then it was like "Yup... enough of that" and hit the highway.   :-+

Take care, my friend. Now's a good time to catch up on those football games you missed. And if you have time to get to Best Buy or summat, grab that BluRay set you've been thinking of bingeing, just in case the www goes tits up.

As a mentioned yesterday here is the build up of the 190mV reference. Overall view of the test set up and adjustment.



After .5 hour. I'm quite happy with this result. I thought the 190mV would drift more than the higher voltages but apparently not. And since I made a major change and reduced the trim pot on all 3 voltages from 10K to 500 ohms I had to tweak some fixed resistor values to get everything to fall into place. And I ran out of some 0.1% resistors so I had to sub some 1%  resistors. I'm going to order 0.1% replacements but I don't see it making much of a difference.



Next step is to mount the assembly into a case and put it into service. Once that's done I'll show how I decided to build that up plus I will publish the final schematic with all the updates.

Oh and BTW. For those of you who think my bench is never a mess.   :-DD

I just checked again. The 8810A is at the Kingston office. It beat the storm. They won't deliver today so I'll get it Monday.

Pulling a damn SEMI motor?

Oh, just lightweight stuff.  :P
Keep your toes out from underneath and you'll be right mate.  :phew:

Only 3 ton, hell I've busted anything I've had that could just handle that.
                                                                                               
Upgraded !
Oh, nothing as mundane as that. Bro-in-law brought me his roommate's Prius; said they got in a accident and asked if I could do anything widdit. (I think HE got in an accident... but whatevs) Pulled the mangled bumper skin off; found the front bumper underneath shoved towards the passenger side about 150-200mm. A new skin isn't too bad; about $70, $200 if you get it prepainted. Though that's unlikely as it already has the cheapest possible bumper skin and hood on it in black gelcoat from a previous accident. Or somebody doing bare minimum to flip the thing.

But the bumper needs to be somewhere close to the right location or I won't be able to get the skin on the vehicle. I think a 3 ton will be enough to make the pull with the bumper still on; if not, I'll have to take the bumper off and pull one bumper cell at a time. We'll see. Doesn't look like the frame stubs accordion-ed too much, and solid bumper cells, no shocks. Just another day in the life, etc. Like I don't have enough on my plate.  :palm:

"A mess" Now we're absolutely sure you're just pretending. The stuff on the desk even looks staged! ;D

I like those little references. Even though the DMMCheck Plus is more accurate, having a number of voltages available in one box is very useful for some quick checks.
