So what happens after a bad storm when your LPG fuel generator runs out? Where do you fill it from? I really like LPG generators, but getting LPG in a hurry can be an issue. e.g. at the moment, FloGas say that they have real supply issues. With a diesel generator, at least I can get more fuel...

I'm not sure where you've got your information from - that's not the real world - a UPS can last for as long or as short a time as you wish. Modern small UPSs have efficiencies in the 90+% range, so they are very efficient - for their SmartUPSs (a very typical small domestic UPS), APC (*) quote...

I've been running the infrastructure for banks and hedge funds as a CTO for 25 years. Regular stress testing and using 3rd parties to run real-time scenarios of their own devising (they don't have your unconscious assumptions) is essential. One thing I've learnt over the years is that when...

It's worth mentioning that UPSs are only designed to cover short-term brown/black-outs, i.e. the short gap between utility power failure and the time for the backup generator to spin up and come online. In the data centre world this is a maximum of 5 minutes and typically far less. I have all...

According to the Royal Mint (Coin Nicknames | The Royal Mint) the name "tanner" comes from a Romany word...

I'm doing this for our house right now. Main complication for us that it's 3-phase. Freezers. You need your freezers to keep running. And we have a heat pump. I would recommend that you get an Automatic Transfer Switch (ATS) and a generator with auto-start. When utility power fails, the ATS...

It's not the CC as such, it's the phosphoric acid in it that converts the rust. You can buy it in 5Ltr bottles on eBay pretty cheaply. There are several such chemicals that will convert the rust for you, but for many if you look, the active ingredient is the same, i.e. Phosphoric acid, you just...

Looks like a Stuart P5 ME but missing some bits. 1930s...

Too much detail!

Good projects @Lorenzl - If you like odd clocks, I run the Google neonixie-l group at neonixie-l - Google Groups Main passion is neon, but will do other display technology if pushed!

Are they WS2812B/NeoPixels? They're great - I've been using an ESP01 and ESP32s to drive them using the Arduino FastLED and NeoPixel libraries. Incredibly flexible. Love your design - very clean.

Make a sauna! This is a salvaged (from a skip!) Hardwood framed double glazed toughened glass patio door, trimmed and turned sideways. Further upcycling - the door from our old freezer repurposed for the sauna door:

If we're talking about L&B doors, here's a stable door I made for the cellar of my office outbuilding. The top bit has to open outwards as the interior floor level is slightly below the top of the door and the bottom bit inwards due to the steps. As the door was to be stained black (Sadolin...

I've been a UKVRR member for about 10 years and used to have several Avo 8s of differing marks (revisions). There were a lot of different Avo 8 models - the "Mark" number is important, plus there were high-voltage, GPO/BT & MOD variants amongst others. Even, Heaven forbid, braille versions...

EDIT: You (Hutzul) may have been replying to the OP rather than the previous post (you don't make it clear), in which case apologies, but my points below about inductive loads and all these types of devices still stand. Did I say anywhere that I had a problem with them? Really? These units...

Modern RF remote controls use a coded transmission that should not trigger on random noise etc. The code from the remote is paired with the unit to be controlled. However, I agree that most of these units, e.g. the Sonoffs, are not suitable for controlling inductive machinery , i.e. stuff with...

This was a National Trust 2016 April Fool... See Moving the Avebury stones for British Summer Time I used to work for them making furniture. Happy days.

I'm inclined to agree - I measured the fallen tree and it's 29m tip to toe. There's a lot of it... Most of the branches have exploded off it already, though #2 son will be back this weekend to help me process it. Will still need to borrow a mini digger for the roots and to tidy up the not...

Well, "Poplar timber" to be specific... We lost a big (60+ ft) poplar in the storms. Can I use it for anything? I'd like to make something out of it to remember the tree by - we still have three other poplars, but for how long? It fell perfectly: Just missing a couple of my beehives by 1m on...

I should qualify that slightly - the utility voltage was measured at the meter cupboard main fuses so as to eliminate any losses due to the cabling within the property. I am an electronic engineer by training so have a fair bit of good quality test equipment myself. Once we suspected the...
