  1. Closed: Re: Missing schematic can anyone solve this? (hot air soldering station)

    OMG!!! Sorry I didn't see that picture that show the traces before. That does make it possible to make the schematic and do this project.

    I may be asking other questions about this in the future...
  2. Closed: Re: Missing schematic can anyone solve this?

    I looked the information over and didn't see that. Are you referring to the picture that shows the pcb and where the components go? If so then that doesn't tell me what connections there are.

    I would like to build a hot soldering station. I have found an instructible that I like, but no schematic was included, so it seems impossible. I have looked for other projects that do the same...

    Closed: Re: Testing Amps on rewound microwave transformer

    OK great. I didn't know that about the DC measurement with this transformer. To stay on the safe side I will just plan on the DC being 1.5v lower than the AC.

    But I did plan on smoothing the...

    My Digital Multi Meter DMM (Extech 470 with True RMS) has settings for A/C power so when I measure A/C power it calculates the RMS and gives me the correct reading. When I measure D/C power I change...

    Brian, Thank you very much for a very clear and understandable response.

    I've been basing my questions on the specs of the drop down power supply which states the input max is 40vdc and 8 amps....

    I didn't understand the graphic at all, and understood the rest a little bit. But I have pieced together things you said with other things I do understand and hopefully have a working plan.

    I don't completely understand this. Please explain with more detail.

    What about automotive fuses? What if I momentarily touch one to both wires? I would guess that if I leave it on too long then...

    Closed: Testing Amps on rewound microwave transformer

    I need a max of 40v and 8a to power my drop down variable power supply. I have old microwave transformers so I removed the secondary and rewound it with 14 gauge wire. I now get 48vac and when I use...
