Tile grout! That is a really good idea. Now that we are on this track, how about plaster of paris/ gypsum ?
The great thing about those is that I may actually have some of that somewhere.
I am trying to keep the cost of this managable since I am doing it as a favour for someone.
Best regards

I am aware of those problems and they are present in these parts. I will however fix that but the main issue is the wire coming out of the groove. The brass you mean is rivets.
Ok, thank you.
So what I can see looks like they filled the slot about 1/3 with somethin and tgen ket the wrie settle in that.
I do not think it was fired after this as there are brass bits that would have melted.
Thank you, I think that frit stuff is likely it. Yes, grout like.
I will study tour links.
Yes, this is a dash light dimmer. It goes in series with about 16W load.

Hi, yes, I saw that and a few others.
My worry is whether they conduct or not. Especially when it says can fe machined etc.
I ban't just buy them to try because all have to come from overseas $$ as nothing seems ailable in Australia.
If anyone perhaps knows of a specific product that will work...
Hello,
I am trying to repair some vintage potentiometers made by VDO.
The problem I have is that tge wire coil was secured in a ceramic slot with some white cement looking stuff. Without that, the wire coil gets literally wiped (!) out of the slot by the potentiometer wiper.
What product would...

i need a custom shape and solution.
The keypads need force ie, not touch.
So there has to be some deflection in the metal sheet when pressing.
I have done some experiments with piezo buzzers as sensors but the limitations...
Hello,
For a new design, I am looking at using an IP68 rated solid metal front keypad that operates on piezo technology.
The manufacturer does not want to disclose how it works but their keypads have a built in CPU.
The general theory so far is that piezo elements are mounted behind the metal...
Hello,
My 2.2kW compressor starting capacitor went faulty. (This is a 240V single phase motor with centrifugal starting switch as well as a second capacitor for running)
I ordered a capacitor from ebay. I tested it and the motor works with it.
But the problem I have is that the new capacitor...
Our unit is overheating due too little airflow from the fans. The fans are not overheating.

That is a very good point.

I can add that our design used a different fan before which was more noisy but wuith very similar specs. We had no failures then except for some noise...
Hello,
I have an interesting problem with cooling fans.
These are mains operated 150mm / 6" fans cooling fans of the normal shape.
There are 2 fans next to each other in a unit or our design.
There are a relatively large number of units failing in the field that have started overheating.
The...
Thank you Klaus for that detail.
The PCB I showed is actually less than 1 year old and is a motor controller for a milling machine auto feed.
I personally have actually done this once on a PCB track where I thought it will help.
There is however no way of telling and I have never seen any...
Maybe this is another stupid question but here it goes:
A lot of PCB tracks in power supplies have a strip of exposed solder running on top of them.
I once thought this is to increase the current capacity of a track but when I looked into that, it appears that solder does not really do much...
Hi there Mathis,
Thank you for all that effort!
However, the measured inductance of this solenoid is much lower than your calculation. It is around 4.6H@120Hz
and 2.6H @1kHz.
How will that influence your simulation?
Best regards
