Ok, had to rearrange the stack to accommodate the load:

Since I can't very well do without the counter, I've moved it to between the pc and the scope:

I did have it higher, but it was blocking the racking behind. I have a lot of things stacked in "storage" in my bedroom... My daughter's bedroom has been repurposed :) Still not big enough :( :lol: Time to add an extension or two? https://external-content.duckduckgo.com/iu/?u=https%3A%2F%...

Here's what it looks like today. It will change when the Tenma load arrives.

They stick out at the sides though, making it impossible to stack 1/2 width items side by side on top of full width ones.

I remove handles because I stack them up. I don't throw them away though

These LEDs were all good, I needed them for an LCD backlighting project

My hot air and preheater are cheap Tenma ones. I checked the earth integrity before using. I recovered some SMD LEDs from an aluminium board yesterday, turned the preheater up to 300ºC, the air to ~50% flow and 400ºC. Wait for the solder to visibly start to melt (difficult here as they had the bare...

As you get older everybody really should come to appreciate Cassandra's plight more acutely. Doing most things for the first time is more interesting than repeating experiences. But by the 10th time... Are you sulking? :lol: https://www.eevblog.com/forum/chat/what-happened-to-tggzzz/msg6185271/#msg...

I prefer an iron for soldering (I use hot air for desoldering) too, and the small stuff is where the nail polish comes in

Having recently started practicing my SMD technique, I can add a couple of tips:

Use a pre-heater! It reduces the dwell time for the hot air drastically.

Sticking parts down with a tiny blob of UV-curable nail varnish works wonders.

Minitrons are not displeasing to look at

What's this, no minitron or magic eye? I'm shocked, and worried!

I dropped the dodgy 1N4148s into my "scrap" bin but I could retrieve them. I'd be very interested to try measuring if it's just one or two. I can improvise a computer-controlled curve tracer and out the DUT in a temperature cabinet. Curve tracing is usually quite good for spotting intermi...

Do you have a thermal imager? Might be worth a try, though this sounds so subtle and inconsistent, I'm still tempted to think about dry joints and connectors. A Pimpernel fault, this one.

It's also not that unusual for crapacitor faults to only show up at or near the working voltage, which can make testing them with the average LCR meter prove to be non-indicative.

More modern buses will have an even lower centre of mass. The engine and gearbox package in particular is normally mounted very low down in the rear nowadays.

AVGresponding

You'd expect the angle on the bus to be larger in any case, due to compression of the suspension on the loaded side Then maybe the slope was tilted at 28 degrees necessary for the test, but the bus was just on the verge of toppling and was at 35 degrees because the suspension was compressed as you ...

My cat loves to steal them.

I discovered some cheap but decent ones on AliX, they fit over the socket, with channels for the bayonet pins
