This little jewel popped up for parts only at a well known UK bomb-site trader, listed for £150. I threw a semi-lowball, (£100), and they came back with £125 (+£16.95 p&p), so I pulled the trigger, as I could see that although it wouldn't power on, the cal stickers were intack, so there was a r...

What a great, descriptive phrase!

Someone replaced the VFD of a Keithley 2000 with an OLED display. Technical details can be found here: https://github.com/RM-Engineering/Keithley-2000-replacing-the-VFD-with-a-5.5-inch-OLED- After seeing this and also stumbling on a Zenwizard video on replacing the piss poor display in the HP 8904A...

Londoners are considerably nicer than the average across the country. You don't realise this until you're a parent and have a buggy to shove around. Anywhere else wouldn't piss on the buggy if it was on fire from experience. In London a veritable army of people assist with doors, stairs and buses w...

Say wut?!?

When they wanted to make them well, they did. My 8300A's both are within a few LSDs of my 8840A, which agrees with my Keithley 2000, 2015THD, and late Agilent 34401A. Not to mention that all my Fluke handhelds agree in a similar way, from the 8060A to the 289. The 8000A really does seem to be an ab...

Or the earlier voltmeter with a digital readout, the 893A. Still my only meter that will read 1kV while taking zero current. None of the normal 0.1mA at 1kV crap :) Perhaps they were different companies, with rebadged low-end scopes, or equivalent to the Tek/Telequipment divide. Is that a null mete...

My other Flukes are stunningly good, much more so than I would have believed. When I get one I expect to have replace an electrolytic and/or clean a switch. If that is necessary, thereafter they are still spot on. Researching it further on the WWW, the 8000A seems to be a particularly crappy model....

Funnily enough I just mentioned my 8000A in Discord in relation to fitting some new NiCd D cells. Naturally Chris wanted me to set fire to it instead, but I prefer to try Med's mod EDIT: Just occured to me to observe that the 8125A which I have more interest in resurrecting the battery option in, i...

Anyone bought wafer switches lately? Had a look at some today for work (I've plenty of stock for personal use) and was shocked at the prices. £30-50 per wafer and £50-60 for the mechanism :shock: That's 5 to 10 times what the were last time I looked. Seriously considering a board full of DPCO relay...

If you let me know what your approximate budget is, I'll keep an eye out and post any appropriate ones I see in the US, in Private Marketplace

Nixies? What are those? I haven't got any device with numitron/minitron displays. No, I don't want cockpit instruments nor petrol pumps, thank you very much. They do seem quite difficult to find. This thing is a real oddball, no manufacturers mark, probably an internal special or something. The tri...

I'll be having to carefully not damage the bloody pins myself, soon enough; bought a R5 9600X on sale, will probably go for a Gigabyte mb with the B850 chipset

These are British roads, they aren't long and straight, for the most part, where you could hit cruise control and doze off. Our roads are very narrow by comparison, and demand constant attention, especially in remote areas like that. If it were a breeze to drive there and back, I'd have it myself.

So what was the outcome, new motherboard and processor? I take it that you were building a new computer so the motherboard was at fault. I think that they could have made the die of the processor larger and used the same pins that they used on earlier processors which had stood the test of time? No...
