| Yet another resistance decade box |

I got better at soldering, the main improvement was to hold the iron on the pad for about 2 seconds before adding solder (to prevent whiskers) Now I have gone from 10% success to 90% i :-+ I got a sample of the "big" switch and I like it. It is easier for me to use. I thought maybe I could wire up external caps and make a cap decade box BUT it is a BCD switch. I never saw one of these. I assume you need TTL logic to make it work, but I wonder if some sort of decade box could be made with it without TTL or MCU? Maybe I should start a topic on it. Does anyone have any ideas? thanks Again I want to say thanks Fortran for this project. The professional quality was a surprise. |

Just because I was looking for different colors ones I ended up ordering some decimal and some BCD. |

Just received a well-packaged set from Fortran. Many thanks! |

I've received the second packet as well - thank you! Cheers Alex |
