and a power cord...no need for the dbt

my limited google indicates possibly it is a kelvin varley divider etc

there is a youtube video of a fluke 881a in action

will be fun to replace the power cord and see if its even close

that looks pretty nice
thanks for the offer let me read up on them and see if I can use it
 

Quote from: saturated on September 24, 2023, 09:19:53 PMalright well i was getting kinda tired of the stacked massive 12x12s and coffee tables


it is def much lighter than the previous set up so that is an improvement

 

dude
they are not 12x12s they are not even 8x8 inches they measured about 7 3/4 x 7 3/4

unbelievable how heavy they are....each 33" long piece weighs 36 lbs

so having those 4 sections alone was 144 lbs....i think

glad i got them out

my house is raggedy too and its on piers...just paid 4 grand to get it leveled

cant be having tons of weight

its a wonder all the people used to have water beds

cant imagine what a full one weighed

and i have decided to invert the shelves (per my original design)
yes originally the two shelves were intended for the  2x4s to be on the bottom and plywood on top
but then i was like dude you are wasting too much space....so at the last minute i decided to go with the current configuration....which isnt working

so first day off and dry weather i will undo it and flip the shelves 180

and add a few gussets here and there

I have some long strips of idk....1x3 or something i do want to put on the edge of the shelves for some SMALL LOW toe board

after that i will be looking to organize cables...test leads...probes etc somehow




i have an old craftsman miter saw i got cheep it aint much but it sure helps alot cutting 2x4s especially at angles

I also have a big table saw i brought home from off the curb it works good but i was struggling with it mightily. halfway thru a cut of plywood it would get in a bind and a thermal switch would cut the motor off.
frustrating indeed....

an older gentleman friend of mine explained i need to utilize the fence to keep everything moving straight.

alright well i was getting kinda tired of the stacked massive 12x12s and coffee tables
so rather than lay on the couch and watch football (at least what we in the US call football)  I decided to build a new set up from existing lumber gathering dust

it was very muggy and humid out....

finally got it in and everything swapped out

and its immediately obvious as i lay here on the couch finally watching the evening game that those 2x4 toe boards have to go

oh well not tonight

its a work in progress i suppose

looks more like some bunk beds than work space

it is def much lighter than the previous set up so that is an improvement

 

I was watching a video on my tv and took a pic of the screen

anybody recognize these guys

pretty interesting
I think in my case some broken glass put the impeller in a bind and so the pump motor burned up

I tried bringing home washers and dryers for a while and fixing and selling but i guess the mentality is different these days
nobody wants a bulletproof roper or kenmore that will last forever....

oh well rant over

while I got you here I am really struggling with trying to understand how to be safe with oscilloscope grounding.
I was going to put a two prong adapter on the cord to unground it but maybe that is not a good idea.

I dont plan on working on any old tube amps or crazy vintage receivers anytime soon.

I will continue to try and learn how to keep my work safe.

thanks for your help.

btw sir I had no idea what an HV Megger was..so I enjoyed reading about it.

nothing to do with it but reminded me of when i was trying to fix our dishwasher.
I removed the circulation pump and tested resistance..it was some crazy number like in the mega ohm range.
I was like "yep thats no good!" and ordered a replacement.
when the replacement arrived I checked resistance on it...and it was the same.

however the replacement pump fixed the dishwasher.

later i was reading that those pumps(motors) are something called ? continuous phase synchronous ? motors



EDIT  supposed to be SINGLE PHASE

thank you sir i will ask him if he wants to part with them

I did some more breadboard tonight same experiment but with a 100 uf cap across a resistor

im confused by that 0.4v but i think my ground adj is off or something having to do with where my scope probes are...idk

its probably supposed to be 0.0v

but the scope def shows what happens

and the multimeter showed the dc circuit voltage readings were unchanged by the capacitor

 

hello sir here is another pic

brief google of "F. F. Hutton" shows they were active 1950s era and known for pneumatic devices.....

  I looked at that tayda website they seem like some good people i will have to try them out next time. 

I unearthed this yesterday wondering if i could use it

pretty funny last night at work i was calculating voltage drop for the ac circuit and trying to figure out which side was +

so i was like oh yeah look at the terminals of the bnc cord from the SG

then later i was

....oh ok........
