| Yet another resistance decade box |
| << < (20/87) > >> |
| Fortran:
The boards have been shipped and should arrive in 1-2 weeks. And the resistors have been ordered and should arrive in about a week. So we're getting close :-+ |

Thanks for the update. Looking forward to it. My IET boxes arrived. Unfortunately, they didn't go unmolested during their former lives, so I've got another project for my queue. |

Just read this and at 98 posts I am not 100% sure what is going on. I think this is a project taking some cheap ebay thumbwheel switches, cutting the guts out and gluing in some custom boards someone is making to make a decade box. If I am right I am also interested in buying some Maybe helpful to summarize what is going on in the 100th post. thanks |

Unless someone beats me to it, this is only post 99 (reply 98), but here's a quick summary: You are correct. And a slightly longer summary: 6x inexpensive thumbwheel switches from China + 6x custom make-before-break PCBs + 54x 1%, 1/4 Watt SMD resistors + 1x enclosure of your wildest dreams --------------------------------------------------------- = Fun little six-decade resistor box |

--- Quote --- 54x 1%, 1/4 Watt SMD resistors --- End quote --- 54x whew ! What size? Could a learner solder them? I finished a SMD practice board, cannot remember how many components it was. If 0402 (metric .1mm - smaller than a baby flea), I probably could not do them. If 6332 (metric - 1 cm) probably can :-DD Just curious - what is the normal way to spec these - metric or imperial ? thanks |
