Re: Interesting findings on the internet

So bored and drunk after an extremely profitable couple of days "digging people out of the shit thanks to Crowdstrike" I am cruising YouTube and find that Chief Furby Mutilator actually produces slightly decent music

Re: Test Equipment Anonymous (TEA) : Discussion and Group Therapy Thread

This was a problem for early Apple Watch users as well. The alu alloy they used had a high nickel content. I couldn't wear one. They changed it around S6 or so as they did with their laptops finally. I dissolve them with my sweat instead now. Yeah, the nickel makes more contribution to chloride ion...

Re: Tektronix 475

The 475's are noisy as hell fully opened up. It was a regret of one of the designers if I remember reading it correctly.

Still respectable scopes though!

Re: Wouldn't happen with an ASR33

Not even surprised. The keyboards I kill least are the chiclet ones which are low travel. Both the Cherry SX and Apple Magic keyboards seem to last the longest (12-18 months each). I usually kill the switches not the keytops though. If they are cherry switches, then you can get replacement switches...

Re: Test Equipment Anonymous (TEA) : Discussion and Group Therapy Thread

I've always found stainless steel watches cause slight skin irritation after a time. I haven't noticed the stainless steel has been even slightly corroded, although there must have been some chemical action. Surgical grade stainless steel is hardly expensive when you consider the amount used in a w...

Re: Test Equipment Anonymous (TEA) : Discussion and Group Therapy Thread

So are my Citizen watches, but I would never like to put them to the test, but a proper true diver's watch, well that's different. Not really. Depends to what standards they comply with or is it just marketing. Your other point from the earlier post is quite frankly wrong. Treating a device with re...

It's known as the Flowers Estate informally. I suspect many people don't know what the capitalised F represents.

The usual warning is the battery doesn't last as long suddenly. That is always noticeable.

Some corrections here... Firstly, they aren't glued in. It's double sided tape like 3M contact strips and it's dead easy to get out. You just pull the strip and they come right out. As for sealed phones, I'd rather have them. They are pretty heavily bomb proof these days and get a lot of abuse inclu...

I actually went to TNMOC and saw that first hand back in 2019. Doesn't seem like that long ago but it's half a decade already. Very impressive bit of equipment that and on the day it was actually operational. Certainly agree with the recognition of Tommy Flowers On that, one of his... Screenshot 202...

I wouldn't want to drive anywhere interesting in Iceland: too dangerous. Well, it was in '84 and '90, but they appear to have sanitised the place somewhat since then - safety barriers by large drops FFS.
