content: So you save £13 now. Then later, when the (ebay) potentially fake/substandard/poor-quality, one fails. You then static (ESD) damage/destroy a £1,000 unit, for a big customer. They get annoyed with your lack of quality, and cancel a £35,000 order. Also, you lose hundreds of thousands of pounds in lost, future business from that now unsatisfied/annoyed customer.Wait a minute, I forgot. You're a hobbyist ONLY. So, no problem, as no customers, and no expensive devices, that may get damaged. Only a £0.03 (3 pence) non-DC rated fuse, which you saved 3 pence on getting the correctly rated fuse.As a hobbyist you only saved a total of 3 pence on the fuse, as you only needed one of them. But the pennies eventually add up, over time.

content: Quote from: tautech on June 28, 2022, 09:38:30 pmThanks.I suppose they have some kind of personality, that gets way too big a buzz, out of creating fictitious threads, and wasting lots of peoples time.I just can't really understand why the moderators/administrators, would allow someone, who has been banned numerous times, and was (originally) suppose to be permanently banned back. If they are just going to keep on creating, way, way too many, possibly trolling threads.It seems silly really, and wastes many peoples time, and could put off, some people, from joining or staying on the forum.

content: QuoteGood point.Thing is, i have heard people saying how they bought cheap from China and it ended up good.....its a good point though......there is so much money to be saved here that it has to be looked into....i may purchase one and test its impedance, to test its ESD goodness.

content: Quote from: tautech on June 28, 2022, 09:38:30 pmFrankly, it's just the same slow speed train crash that we've witnessed for years, right back to the lighting exploits. Only the subject changes - I think it the first time he's actually tried to assemble something though ()Nothing new to see here, just a peak in the thread frequency and inainity.

content: Quote from: Faringdon on June 28, 2022, 09:47:50 pmAlso, usually an engineers time is rather valuable/limited. So is it worth trying to save small amounts of money, then losing valuable minutes and hours, checking/fixing on the bits and pieces, because the buyer cheaped out on everything.Buy cheap, buy twice.

content: ...Thanks good point, i must admit though, i really dont know what to think now...i once worked for a company where an engineer came to work carrying a Far Eastern "cloned" version of our product......absolutely everyone (everyone!) at the co said how disgusted they were that it had been done.....it later emerged...it was the company itself.....i guess they knew that if they didnt do it then someone else would.I have worked at places where they had arranged bulk builds in the Far East...and yet assured big customers that everything would be designed and built in-house in UK.............they would invite the cust round to see our manufacturing facility....at lunchtime the custs were able to walk freely about....i caught them near my desk.....discussing with each other how there was no way that this place could service that size of order...they were absolutely right....So i am not sure how quick i am to write something off as being cheap and from Far East..when the "UK alternative" may well not be that...and may be from the Far East anyway.In the past, PCBs and transformers that i have had ordered from China were always of superb quality...and the Engineering contact superb aswell.

content: Just tested the above ESD mat of the top post and its fine.50cm x 40cm4 poppersone yellow plugone double poppered cableone cable with popper and 4mm plugother bits and bobsI measured the resistance through my body--->through the blue surface of the mat---->and to the popper...it was some 150kOhms...that is absolutely fine for the assembly i am doing.Woudl have been higher res if i had put insulator under the mat instead of just having it on the floor (lino)
