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

Re: HP 211A
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 chipsetSpecmaster wrote: ↑Fri Apr 11, 2025 2:24 pm Oh, but those photos are of an AMD AM5 socket and AMD Ryzen processor?

Re: Going free: Fluke 760A Voltage Calibrator
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.

Re: Post a picture of a cat
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...

It quenches the arc by removing heat, and also there's a chemical reaction making the metal-filler fused product highly resistive.

All modern HRC fuses have some sort of filler for arc quenching. It shouldn't be sand: https://www.electricaltechnology.org/20 ... types.html

Those have been heavily compressed, to 0.75MB/image, and to have artefacts surrounding the lines. They appear to have been taken with an "iPhone X", so I would expect better. I can automatically improve the text and schematics, but the images don't improve. Is there any way of getting the...

I uploaded the raw jpegs, no idea if the forum compresses them at all. Erik isn't set up for scanning, I'd guess he used his phone or a digital camera
EDIT: The forum definitely compresses the images, down from around 1.6MB to 240kB
