Did you make your crowbar? I'm a bit late, been away for a couple of weeks. If this is a standard 12-14V PSU application ie there's no RF component then the common or garden SCR crowbar with a tight tolerance zener trigger should be fine. They're a bit hit and miss in PC 5V rail applications but...

Geez, you're lucky you were wide awake and nice dashcam footage by the way.The Audi looked like it might have clipped the car going your direction in front of you as well as the obvious stationary one, If she didn't she was pretty damn close. She was probably on Whatsapp or snapchat, whatever...

My local wholesalers sell a brand called 'Waco'. Waco do everything from light fittings to tools, the hole cutters shown above are disposable and are cheap as chips (around ZAR30.00 or about one quid fifty for a 20mm) and they're actually pretty good...

The only time I've used parallel fuses in a panel by design was to accommodate an extraordinarily high PFC. Some manufacturers will supply pre-matched fuses specifically for this and we actually ended up with 4x fuses in parallel to meet the potential fault current requirements. In some cases it...

One of these  in a cordless drill as mentioned at slow cutting speed with a bit of oil. Once you're through the s/steel and into the wood change to a spade type wood bit. It's something we do regularly and I don't see you'll have any problems in stainless that's under 2mm thick.

Sounds like they've covered all bases to make maintenance and fault finding as difficult as possible. I'd just replace the fuses and check the fan motors for slow starting or any other signs that a motor capacitor or one of the windings might be problematic.

No such thing as 'fit and forget' filters as far as I know. I'd expect any filters to be easily accessible. How badly were the fuses blown? Was the wire just casually separated or was there molten metal bits and large blackened areas visible inside the fuse? Sounds like too much to be a...

I'm sure the physical injuries were far less traumatic than thinking you were free and single then finding out you're not....

@CanoeboyI'm sensing a deep-rooted hatred which probably means you've got bad first-hand experience with them :) .  I've never come across that particular make in this area, I've got some experience of Systemair units but maybe these things are different.

Maybe make the offset hooked tang from a piece of thin copper busbar and bolt it permanently to the battery. Then drill it and use a standard crimp on lug on the wire(s).

If you're not familiar with heat recovery systems maybe just check the condensate drain is clear and clean the filters which should slide out without too much dismantling. If that doesn't clear the alarm tell the customer to get the agents in.

Isn't that somewhere near Essex? :)

If you change the date on your PC and set it back to sometime in the past you're going to encounter all sorts of things that will no longer work. Why did you roll the date back? **edit** Did you change the date or did you do a system restore? I'm wondering if I misunderstood......

I still don't understand how the 'case' of declining to sell untoasted bread could have got before an official HSE committee and also why they actually thought they needed to preside over it and produce a verdict......

Cane rats are pretty big by UK rat standards, they grow to the size of a small Staffie in some areas. They're not eaten so much in SA maybe because they're not very prevalent here due to farmers killing them on sight I'd guess but they're often on the menu when I go to Mozambique and it's...

I'm not sure if he was around here or not but he was on another forum and this probably isn't the place for the gory details. Let's just say he taught some people that everything is not all is always as it appears when you it comes to people/personas on the internet. ;)

He's a handsome looking boy but I can't tell if he's smiling or snarling.... or maybe both at the same time. :)

I think breeding is an issue that means there's underlying aggression in a dog even if it's trained and looked after correctly, I saw it with him when he went for the Rottweiler, he was like Jekyll and Hyde.and a normally placid and happy dog just switched to wanting to kill another dog in an...

Probably Chihuahuas, I know someone who had one and it was the most aggressive, low down, spineless, underhanded creature I've ever come across....and that was on a good day. 

A little bit of dentistry with a Dremmel tool and you should be able to solder it.
