Picking up the tools again.
I haven't touched a soldering iron for about fifty years, so I thought of
using this shutdown time to get geared up for a bit of tech activity. Got myself a USB scope, a couple of multimeters and a dual stabilised DC power supply so far. I have loads of new components in the loft (or at least they were in 1970 - 1980) left over from various commercial/military projects. I hope all this will keep me interested for a while. I started building a novel design for a human presence/movement detector in 1976, but shelved it because of work commitments, so I will probably continue with that for starters. Sorry, I am just rambling in my old age. |

Sorry, I am just rambling in my old age. Like yourself, my electronics construction is in abeyance. Your old components should all be OK apart from the electrolytic capacitors. In expectation of a revival in interest, I have been sidelining my 40 year old components and building up a stock of SMD, in particular the largest 1206 sizes before they disappear. (0201 anybody?) But what I will not be re-awakening is my Henley Solon soldering irons because several of any size of SMD will fit on their copper bits! Perhaps something to stimulate a 50 year old interest is the PDP11 and PDP8 emulator kits ... https://obsolescence.wixsite.com/obsolescence |

Hey, it makes a change from the B that was replaced with the C word. ;-) Most of my recent 'electronics' projects have revolved around the Arduino micro controllers but there is also a certain purity with something that just works made from discrete components. Such an example is a LED I fitted to my Weller Soldering station that comes on when the element is heating. ;-) Cheers, T i m |

Cheers, T i m [1] The last being an 8 channel disco lighting controller that had 4 main programs and other timers that allowed the automatic stepping between them or sub functions (like a auto reversing running light with analogue control over the speed and change of direction (1 x 556)). Zero crossing detection between the opto-isolated outputs and the triacs, all made on Veroboard and hand wired using solid strand insulated wire. All that (logic) could now be done with a single Microcontroller. ;-( |

I'm sure there could be a number of one off things disabled folk might
require these days that are not catered for by mass market forces. Incidentally a person detector is very close to a Theramone.

But completely and utterly missing the point of the electronics and nostalgic exercise for a common used electronic component. It wasn't about timing or timers at all. Any idiot (that can speak) can 'use Alexa' but not everone can solder (well) And end up with a grossly inferior timer. See above. or do other practical stuff. Like work out how to get the best timer and even get real radical and work out hot to get a lot more force on a tree that you are bending back to where it needs to be. Irrelevant. It was about nostalgic / electronics, not using Google or Alexa.

If you havent even noticed that some ****wits try desperately for an insult... As you yourself are doing... Nope, if I want an insult from you I'll just prove you wrong in public. However, I wasn't looking for one (so you are wrong yet again) but simply trying to get to the bottom of your issues. Are you bored and so willing to do anything to get attention (which usually gets you killfiled instead), can't help yourself (1 tinny short of a 6 pack) or really don't know how to be social? I give you it is tricky here, with the weirdo's spilling over from uk.r.a (because they have ruined that place) with some thinking the send button is the trigger on a megaphone (like Reay). So, rather than having to create numerous accounts in a desperate hope that some will read you before working out it's you, why not try just being civil and reasonable? If you know something someone has said is wrong, just question them politely and maybe include a link (unless it's Ray and you will be there all day and he won't listen anyway). Believe it or not, I would be mildly interested to hear what (diy related ideally) gear you had found at garage sales or stuff you had picked up broken and repaired. Go on, give it a try, what have you got to lose? ;-) Cheers, T i m |

I came across some of those 42 years ago in the CEGB's private telephone network, replacing in some way either Uniselectors or Strowger switches. The interesting thing is that there was a low power incandescent bulb permanently lit inside the cabinet and when I queried this, ws told that it improves the behaviour of the Dekatrons, but I guess that was because of the background heating it supplied rather than some optical effect? |

No, but I am concerned that if I sell it on having been unopened in its box for 3 years that there might be some lithium battery that has discharged so rendering it unusable. I did offer it back to the vendor but they took the attitude that it still coounted as second hand despite still being unopened in the box and only offered £500 for it so I thought if that's all it's worth I might as well bin it to save myself from any ebay hassle, etc. But you don't really want it JIm, becuase you know how you play with things and then dispose of them? |

If anything, Ebay etc makes it easier than once. Not quite sure what you mean by genuine. Most such things have several different makers. -- *Learn from your parents' mistakes - use birth control Dave Plowman London SW To e-mail, change noise into sound. |

I came across some of those 42 years ago in the CEGB's private telephone network, replacing in some way either Uniselectors or Strowger switches. The interesting thing is that there was a low power incandescent bulb permanently lit inside the cabinet and when I queried this, ws told that it improves the behaviour of the Dekatrons, but I guess that was because of the background heating it supplied rather than some optical effect? I believe light has an effect on neons striking, but I don't know much more than that. -- Roger Hayter |

No, but I am concerned that if I sell it on having been unopened in its box for 3 years that there might be some lithium battery that has discharged so rendering it unusable. I did offer it back to the vendor but they took the attitude that it still coounted as second hand despite still being unopened in the box and only offered £500 for it so I thought if that's all it's worth I might as well bin it to save myself from any ebay hassle, etc. But you don't really want it JIm, becuase you know how you play with things and then dispose of them? no I don't only if I don't like them..kept the IC728....... |

Got myself a USB scope, a couple of multimeters and a dual stabilised DC power supply so far. I have loads of new components in the loft (or at least they were in 1970 - 1980) left over from various commercial/military projects. I hope all this will keep me interested for a while. I started building a novel design for a human presence/movement detector in 1976, but shelved it because of work commitments, so I will probably continue with that for starters. Sorry, I am just rambling in my old age.
