I would have visited this w/e but you be out.....lol --- End quote --- Where you at your daughter's over the weekend ? Rob --- End quote --- Yup, visiting yet again....the boys are growing bigger.... I think they'll turn out to be tuff geordies..lol... :lol: |

--- Quote from: RobWilson on May 03, 2016, 03:01:26 PM ---Ok lads A question for the electronics chaps , I would like to build a circuit that would charge up a bank of capacitors to anywhere between say 10v to 35v and when charged to the set voltage disconnect the power supply from the capacitor bank . Any pointers ? :scratch: Rob --- End quote --- Nope, no Pointers, mates got a Staffy :lol: Depends on what you want to do, I'd use a PIC, one analogue channel to read a pot, and set the reqd. voltage and another to read the cap. bank volts. Use one digital channel to drive a relay to disconnect when it's up to what you want. How big is this cap. bank anyway ?? Not a good idea to try to charge a damn great heap of the things from zero without some attempt at a current limiter. A big cap. is close to a short circuit at initial switch on ... :zap: Stresses the rectifier no end ... You going to Doncaster BTW ??? Dave |

Dave --- End 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 |

Harrogate Show is at Doncaster this year, nowt to stop you taking your own bacon / sausage butties if you want. Or even a Hog Roast if you're that peckish ... :clap: Dave |
