[/quote] :lol: :lol: :lol: :lol: Hi Dave , whats on at Donny ? will there be bacon or sausage butties involved ? :D Micro controlled , mmmmmmm sounds like a plan :thumbup: I was planning to use a current limiting resistor to charge the caps . As to the size of the cap bank thats still a big question mark :palm: , I would like to build a small cap discharge spot welder :zap: Rob [/quote] Rob, My stud welder has 200v caps of 66,000 microfarad, that charges up to a max of about 180 volt and will fix an M6 stud as per this thread (no pun intended !): http://madmodder.net/index.php/topic,10358.0/all.html |

Cheers for the input lads :beer: Looks like I will have to do some reading up on capacitors , a classic case of Wilson running before he has even learned to crawl :palm: Canny stud welder Andrew :thumbup: , good to read you got it all fixed . Used one myself many years ago :dremel: , I do remember one lads steel toecaps looking like two hedgehogs one morning when he came into work :lol: Rob |
| PK:
A simple constant current circuit is better than a resistor because it will allow faster charging. I used this for a small anodising supply once. |
| RobWilson:
That sounds a much better idea PK :thumbup: , something I will look into . Cheers Rob |

Hi update on my non working airband receiver. it's still not working. :doh: :doh: I've checked all the elec caps, the're round the right way, all the chips are right way round in the correct places, I unsoldered one leg of each diode ( 4 in total ) and tested those, the're the right way. the transistors are the right way according to the silkscreen. I even pulled all the chips to check if I folded a leg over inserting them, all OK. I'll try some voltage checks next. Roy. |
