Amazingly Americans still use top loading washing machines. We have a high efficency washer and seperate heat pump drier (super efficent) both front loading. Most full size permanently installed washers sold here are also high efficiency front loaders but yes, you can still buy top loaders. Most po...

I know it is fairly typical in the UK, and probably in most of the EU, to have a clothes washer in the kitchen. That is unheard of here. The washer, along with usually a dryer, is located in a large closet or the basement. In this apartment complex there are 2 washers and dryers in the basement. So ...

Have you read the classic "Gödel, Escher, Bach: an Eternal Golden Braid" ?https://en.wikipedia.org/wiki/G%C3%B6del%2C_Escher%2C_Bach Copy arrived today with a thump. It isn't a book I could read from end-to-end: too detailed, convoluted (deliberately!), and abstruse (chosen style, difficu...

I guess I'm too much of a simpleton to understand what the fuck he's talking about.

Man you software guys are weird.

More 485 fun. I was about to put my original parts mule back into storage and I noticed these 2 options listed and was curious as to what they were. https://imagizer.imageshack.com/v2/xq70/923/nBUVgk.jpg Option 4 is additional EMC shielding and option 78 is P11 (blue) phosphor! Really? So I pulled t...

Human, this box is unacceptable. It has holes in it.

Pat, sorry to hear about Gilmore. We do grow attached to our pets. And yes, Schottky does look exactly like Harley.

Our cats are the only domesticated mammal that isn't "domesticated". Case in point. About a month ago one evening I came into the kitchen and found Harley laying on the floor next to a dead mouse. Harley is an indoor cat and has never seen a mouse and in the 2.5 years we lived here we've n...

Harley likes to sometimes give me a "love bite" on my hand and his fangs break the skin. He doesn't comprehend that it's painful. My cat Loki has the same habit. While stroking him, you have to be careful, otherwise you'll get a hurtful "love bite". Does he also bite you on the ...

This guy also found out the hard way. Supposedly the tiger was just giving him a "love bite" :roll: https://abcnews.go.com/US/oklahoma-animal-handler-attacked-killed-tiger-performance-sheriff/story?id=125792975#:~:text=Oklahoma%20animal%20handler%20attacked%20and%20killed%20by,demonstratio...

On the subject of cats (albeit large ones), I had breakfast at "The Shack" https://www.communityad.co.uk/exclusives/100-years-shack-cafe-hook/ on Saturday. There was a poster above our table telling of a little history. Apparently, the owners of The Shack also ran a fairground where one o...

Small and light electrons tunnelling through barriers is ... old and boring. So how about hydrogen atoms tunnelling through barriers? https://pubs.acs.org/doi/10.1021/acscentsci.5c00943 and an easier exposition at https://www.science.org/content/blog-post/tunnel-away Any practical applications? Did...

Shame about the unfixable 485, but at least it's proven its worth by repairing another. My 485's EHT died completely, leading me to suspect the transformer or drive transistor rather than associated rectifiers, but I hit the same problem that it was buried and I had another (brand new) 'scope (TDS3...

A little off topic but I must inform bd139. Your heart throb buxom redhead Christina Hendricks is in a Netflix series "Good Girls" which is a pretty good watch in addition to the eye candy. And boy is that some nice eye candy. :lol: I don't know if that series is available on Netflix UK bu...

More 485 drama. I pulled out my 2nd 485 to give it a dust off and power up and the A Triggering was nowhere to be found. So I took the "low road". I pulled the trigger board out of the 485 I condemned yesterday and installed it. Problem fixed. https://imagizer.imageshack.com/v2/xq70/924/Ao...

Here's one of the functional 485's on top of a 2235. The later series of portable TEK scopes tend to be much easier to service with the advent of LSI circuitry. Those 465/475/485's were still packed with discrete components. https://imagizer.imageshack.com/v2/xq70/922/8ngSAy.jpg And now that bench 2...

Gang, the party is over. The following pictures are the parts unit with the trigger board and PSU board removed. U1600 (X6 multiplier) is located in that board right rear with the shield. There is no way to get that board out without nearly disassembling the entire scope. And to add insult the manua...

He's dead Jim.

Let's clear up some confusion and I found the reason for the compressed trace. First, the trace is linear as shown. Second, there's a vertical issue too. At that attenuator setting (1V/Div) that trace should be 5V or 5 divisions high. It's barely 2.5 divisions. I verified on another scope that it is...

Getting some lab time here is like pulling teeth. Something always seems to come up that's higher priority. But I finally got the 485 reassembled even after a side track of pulling the PSU board to retrieve a dropped screw inside. So initial power up. No smoke which is surprising. PSU voltages in sp...

Have seen lots of brown tants. Just as bad as the yellow ones.

If you're running Linux you're probably OK. Windose 11 here and that Netgear program is built into my router so it never got near this computer.

My Netgear Amour program blocked that site as potential malware. You may want to scan your computer.
