I think it was in the 70s they used to wire houses with aluminum and it was not good.
When I did remodeling I would run across a house that was wired with aluminum, very rare now a-days.

For electronics contacts - yes. Even if it is available, I doubt whether many of us can afford to wire their entire house with gold wiring.

Actually, silver is the best conductor.
But gold has the advantage of being more durable due to
its high resistance to corrosion, tarnishing and oxidation.
So for critical connections gold is the preferred conductor.

Yes, long time since I heard this.
Thanks.

The AL wire wasn't the problem. The problems were not being aware of the importance of anti-corrosion measures (especially when joining Al and Cu) and the need to enforce a torque spec on all screw down connections.
AL has always been used without problem for heavy gauge feeder lines, and if connected properly is perfectly safe for standard outlets and hard wired devices. The initial standards for using it with 15/20A circuits was just 🐘💩.

I imagine, given the age and solidity of your supply, that the first thing after the fuse is a hefty transformer. Unfortunately if there is a short on the primary (or even secondary) then getting it rewound is going to cost more than your car.
An alternative point of failure (and hopefully more probable) is the rectifier bridge(s) after the transformer. That should be a very cheap fix.
Time to get the ohmmeter out!

My mind immediately though "hmm, you could be onto something..." the danger if the transformer insulation is going is fix it in one place it will pop in another, a possibility I can't lay hands on the link but there was an eBay seller who had a lot of spares for Heath-Kit, Crown and others. Mind you the thing is 'To fix the fault that caused the fault'.

I was thinking more along the lines of a small thermonuclear device.

I'd be happy to load you up some fuses, Mike, but primers are awfully expensive and rare right now.

Fuses do actually degrade with age, especially if the're rated a bit near the running current. The inlet fuse will almost certainly be subject to many times its rated current for a short interval every time the PSU is powered up (due to charging up capacitors), and each time they'll warm up a bit and lose a bit more "life". Could be your fuse just got too old and tired.

We have a lot of power glitches here also. We live in a very small community way out in the country. We're so far out they have to pipe sun shine into us!

Interesting. When I search digikey for "fuse", I get a lot of them. Filter on product status: active, mounting type: requires holder, fuse type: cartridge, glass and I got over 1600 hits. Most of them can be ordered as single, but some can only be ordered in quantity.
Or, just Google "old car fuses" since cars used to use the same type.
Have to keep this old equipment working. I hope it's just a problem with an old fuse for you and that the fuse blowing is not just a symptom of another issue.

Hi,
I have to export a 'long' value from an unmanaged dll to a VB app.
I do this with other data types like int and bool, works fine, so I more or less know how do do it.
When I do the same with 'long' the call crashes.
Where there any samples out?
What is so special with 'long'?
Thanks for helping.
With best regards
Gerhard
extern "C" { __declspec(dllexport) long GetCurrentFileRawFilePointer (void); }
extern "C" { __declspec(dllexport) int AwaitCycleDoneFor (uint); }
extern "C" { __declspec(dllexport) bool isDataLinkClear (void); }
First line fails, other worked fine.
Declare Function GetCurrentFileRawFilePointer Lib "GeoMon4D_iMX7.dll" () As Long
Declare Function AwaitCycleDoneFor Lib "GeoMon4D_iMX7.dll" (timeout_ms As UInteger) As Integer
Declare Function isDataLinkClear Lib "GeoMon4D_iMX7.dll" () As Boolean

It's because of the extra spaces in this line.

It's a long value, but the VB code requires a short - so you will need to zip the value - which should compress it nicely - and then pass it.

Better to remove the zero-bits because they are worthless anyway.

I used C/C++ many years ago, as I recall that the long in C/C++ is actually 32 bits, the 64 bits type is called long long (or something like it), whereas long in .NET (and many other later languages) is 64 bits (see here[^]).

Many years ago, true (mostly). Today, at least on the 64 bit Archs (x86-64, arm-64, risc-v-64) I'm aware of, a long is 64 bits, as is a long long. And going back even further in time (8086 days), an int was 16 bits, and longs and long longs were 32 bits.

so they are referring to kind of physical unit rather than logical unit ...
