Hi DIYers, The nut (I think it's called on my big vice is stuffed). Is there all one who sells them?

For what it's worth, a trick to know is taht the DHA booking site will give you a date range to go to the bank ... and there will never by anything available. What you need to do is manually type a date range (ignore the picker) a week later, and then you can get availability.

I had a scratch around to find who serviced my Morso 06 ... but can't. But I see the agents are now "Morso South Africa" morsoe.co.za so they could recommend someone i guess. I needed it swept, checked and a couple of the bricks replaced. Very expensive parts...  service was not too expensive...

Getting a UK smart plug may be hard -- but this is the CBI Astute smartplug, it's rated for 16A (plug...) but has a 40A relay. Should last forever, Android & iPhone app. https://cbi-lowvoltage.co.za/asp-qr And then use one of these. A kludge, but easy. (Disclosure: I work for CBI)

This reviewer didn't like the player/remixer designed by kanye with some design shop called kano. https://slate.com/culture/2022/03/kanye-west-donda-2-album-review-stem-player.html

I needed some 2K paint to overpaint a chrome trim on my car... Joe's do a 2K aerosol for R410 inc Vat, they can ship.

Until two years ago I had a C220 (W202) that I took to German Autohaus .. the last interaction with them was for them to have a good hard look at my car and say "get rid of it, the cost to sort it out is not worth it". I appreciated their thoroughness and honesty. I know they do a hell of a...

If you want to do load control/load lockout, CBI AstuteSmart range comes as "smart isolator" (2x4), "smart plug" (4x4) and "smart controller" (DIN/minirail mount). Proper 40A relay, proper terminals, SANS cert. (Disclosure, I work for CBI...). This is the consumer range, uses the Tuya back end...

Wi-Fi Assist is one of the silliest things Apple has ever done, and it's a list of some gloriously silly things. Why implement WiFi Assist (which is actually "failover to LTE at the drop of a hat") and not, say, polling WiFi signal strength of known networks periodically and automatically...

Good to know. I've always assumed that the .3R is leads, because I suppose DMM manufacturer can't assume that you'd be using their leads and pre-emptively calibrate for that. It makes sense on the ~20mV being an artefact of noise and sampling electronics on the high impedance inputs, as on VAC...

Something that's always bothered my about my Fluke 117 is that it feels like it needs calibration ... in that on the mV setting with nothing connected it'll sti at about 20mV; and on resistance if I touch the probes directly to each other I get ~0.3 ohms. Is this normal behaviour? I've had it...

Thanks for the interest, gents. Haven't had time to have another poke and measure. Next week when back from glamping in Limpopo. The reason I think the scope is reading right (or at least that I'm setting it up right...) is that if I ground inputs I adjust axis exactly on zero line; if I switch...

+1 on what handsome said. Flat cables would have lower capacitance as the narrow bits are facing each other. Capacitance comes from how close conductors are and the surface area presented by each to the other. Flat cables are normally a minor second down on regular cables.

+- 1.5V ... afaik "standard" line level in is 1.41V peak. I'll run it for a bit and try record the pop/crackle. Very faint. Like a rat in the ceiling in anther room. Will measure across the 270R

So I actually did this last week but got busy to do update. Replaced three of the 15V zeners with 25, and presto plate voltage now sits at a solid 175V. Nice to see the theory working. The top of the wave is less squished, now almost imperceptible... but I'm worried I'm over-cooking things...
