Thread: Soldering Electrical Connections to NASA standard
22/04/2021 17:27:30

The EU mandate that all electrical equipment must be assembled using lead free solder has probably done wonders for the sale of replacement electrical goods, how many circuit boards have failed because of the growth of tin whiskers causing shorts and failing joints, we are currently on our third Sky Q box due to failures. Perhaps now that the UK is separated from Europe we can see some common sense taking hold and where necessary we can use leaded solder, I acknowledge aviation equipment has always had an exception, there seems to be an obsession in the EU about lead and its dangers, shotgun use of lead ammunition is one of their pet hates. I remember as a youngster when eating rabbit we were told to spit out the black bits as they were shotgun pellets, how many of use in our seventies and eighties are afflicted with lead poisoning! Sorry to go off topic but I feel strongly that the EU regulations were excessively overprotective and detrimental to electrical product life. Dave W

Dave, I think Chester Champion refers to a mill, I have a Chester Champion V20 mill. Dave W

Thread: Covid

Wife has just had her second AZ jab, after her first she spent a week mainly in bed with flu like symptoms, after the second she was expecting similar but she had three days where she felt very tired and every time she sat down fell asleep. After the three days she felt right as rain. I had Pfizer jab and after first jab had two days of blinding headaches, now awaiting second jab anytime soon. Wife had to have the AZ jab on medical advice because she has previously suffered an anaphylaxis episode, got an adrenaline injection just in time she was nearly a goner then, fortunately it happened in hospital, consequence of an iodine dye injection.

Thread: Trademark Infringements

Following on from the comments of HowardT and MichaelG reference the traceability of materials that are used in Aerospace, Nuclear and other critical engineering situations, I have worked in both Aerospace and Nuclear industries, the supplier of the materials, supplies the necessary mill certs identified to the specific materials which will bear the “cast number” on every piece of the items in the batch. If the materials are broken down into smaller units then the original cast numbers will be used to identify those units. Where I worked we used a lot of Stainless type materials in bar form and castings, all were supplied with mill certs, fairly common practice. An interesting situation came to light a few years ago, I believe it was in France, a major supplier of high grade certified material used in mainly Aerospace but also I believe in Nuclear, had been falsifying the material certification to show that materials were of the required standard when they were not. This revelation had serious implications for certain industries who were supplied by this supplier, it all went very quiet after the initial disclosure. It shows that a system is only as good as the people who are operating it, quality certifications are meaningless unless there is a will to play the game. Dave W

Nigel, I am unaware of the outcome it was an article that I read, one would hope suitable action was taken. Dave W

Rob, thanks for the info will investigate. Dave W

Thread: LED Tubes in the workshop
08/04/2021 19:57:52

The supplier that I obtained the LED’s from is a company called International Lamps Ltd. They have a website, I use them for obtaining the UV lamps for my ponds, always competitively priced and supply reputable brands like Phillips. Dave W

Thread: LG TV ... updated webOS
08/04/2021 19:40:24

To illustrate how our gadgets are working autonomously, we have Sky Q and frequently we find that it has selected programmes to record without any input from me or the wife, such programmes are children’s programmes and obscure subjects that I have never viewed or would have any desire to so I regularly go through the record list and cull any that we haven’t chosen.

Another probably relevant item is something that I came across a couple of years ago. The African National Congress commissioned the building of a new headquarters to cover the whole of Africa and it is located in I think Ethiopia. The Chinese government volunteered to fund and build this headquarters for the ANC.

After the headquarters was completed and in operation one of the IT operatives was working late one day into the early hours of the following day and had need to visit the room where the main servers were located. He couldn’t understand why the servers were all frantically working away when nobody was at work and all the terminals were idle. Subsequent investigation revealed that ever since the system had been commissioned, in the early hours of every morning, all the transactions that had taken place on the computer system the previous day, were downloaded and sent to a computer somewhere in China. I think we were fortunate that we prevented any more Huawei components being incorporated into our 5G communications network. Dave W

Thread: LED Tubes in the workshop
08/04/2021 19:10:37

I was very sceptical of replacing the fluorescent tubes in my workshop with Led replacement tubes because until recently they were very expensive, I found a supplier who was selling four foot tubes, with the led fuse to replace the fluorescent starter for £4.55 plus vat. I decided to take the plunge and fit six in my workshop, fed up with the way fluorescents struggle to start and flicker in a cold workshop until they warm up. The light output is nothing short of brilliant and of course they are at full output in what seems milliseconds, the only problem that I had was that one of the light units was a high frequency unit and you need to alter the internal wiring in order to fit an Led tube. I had to find out what alteration was needed, thinking it must be something complicated, it wasn’t all I had to do was open the light unit remove the high frequency choke unit and this left just wiring the incoming live and neutral to the respective pins on the tube caps and link the caps together. The tubes I fitted are made by Energizer and quote a 30,000 hour life expectancy, I realise this an averaged figure and in reality some tubes may fail before this point but I am more than happy with the outcome, brighter lights and half the energy consumed.

Frances IOM,

Do we need a vaccine passport, aren’t we being tracked by the miniature micro chips that are embedded in the COVID Vaccines!!! 😇. Dave W

As Dave has pointed out the transfer of agencies from the Civil Service to Private Enterprise means that the whole culture has now changed with Profit now being paramount, is that good, does that bode well for the future? Dave W

Ships in the canal only travel at about 5 knots, otherwise the wash would destroy the banks of the canal, hence why it takes nearly a day to transit the length of the canal. Dave W

It was a similar situation when I transited the canal in 1957, was on a British ship and we had just had a military campaign to retake the canal, albeit unsuccessfully, so very hostile situation. I went to Egypt in 1960, visited Cairo and there was still a coolness to British people. We were warned by our tour guide not to go out after dark alone as very likely to get knifed, such was the strength of feeling then. I would put Egypt at the bottom of my list of favourite countries.

I doubt the battery can run all those lights at full output without the engine running, probably would be a different story if 12 volt. Dave W

To digress slightly I think that we should all be concerned about the type and volume of information that Amazon is accumulating about us as individuals, to what purpose is the vast database to be put ? Dave W

Mobile phones are continually emitting signals as they lock onto mobile phone masts, how do you think that police and security services e.g. GCHQ are able to track the transgressors when they have their phones switched on and then lose them if they switch them off. Big Brother is always with you when you have a mobile phone switched on. Dave W

Thread: Barrier Creams
26/03/2021 19:36:34

I suffer from contact dermatitis, not from contact with oils and greases but from detergents, gets me out of washing up, to keep my dermatitis under control I use a hand cream called NURSEM, it is available off the net. The formulation requires only a small amount to treat your hands and surprisingly it dries non greasy or oily which is a bonus if in the workshop, although it is not marketed as a barrier cream I have found that it works as one when I use it. The product was developed by a member of the medical profession to combat the effects of continued use of hand sterilising gels. Dave W

The Mitutoyo plant at Andover didn’t manufacture anything many years ago when I went there for a demonstration of a CNC Coordinate Measuring Machine which I purchased for the company that I worked for. Andover appeared to be a sales and supply depot. Dave W

It is an established fact that your mobile phone will listen to your conversations, I don’t mean those using the phone to communicate but any conversation that it can hear, we don’t switch our phones off when not making calls but the phone is still active and able to listen in to what is going on around it, just like Alexa does.
