Perfect!

Hi Zysurge, Yes indeed, that is just what I wanted to confirm. Technically, I think my load, the model, goes on the two middle terminals and the battery and wall wart go on the ends, with the +'s on one side of the switch and -'s on the other. Thanks for the quick response and the image as well! Che...

DPDT switching- two power supplies

Hi all, I am working on a project and I want to use a DPDT switch and connect it up for two different power supplies. I want to be able to switch between "off," Battery power, and wall wart (from AC) power. The model is wired and I'm ready to connect the lights and power supplies. The stan...

MF,

Thanks for the additional information. I have heard about tinning but I knew just enough to cause trouble. All is clear now, so thank you again for the instruction.

Hi MF, Thanks for the input. Just so I am clear, your recommendation is to apply some solder to the LED and resistor leads before cutting them shorter, join them together mechanically, then re-heat the joint area to solder them together. And the same would apply to solder the resistor and LED Lead t...

Soldering lighting parts

Hi all, I've had the basic LED's and resistors for a project in hand for a while. I'm new to lighting, and it's time to solder the bits up and install them. Both the LED's and the resistors have long straight wires on them, so the question is, can I safely shorten them, by up to half? I'm thinking o...

Soldering question- wires

Hi all, I am running wire in my Y-wing project and a friend of mine has offered to solder the connections. I had him do a couple of connections for the main power, hooking up half of the power plug set. He ran the wires through the mounts, twisted the wire together, applied heat and ran the solder i...

I also did not buy in bulk, although there are economies to be had if you plan on ...

Can I trim and bend the leads on LED lights?

Hi all, In thinking through all of the design issues around lighting up my y-wing, linear space for an LED plus it's resistor may become an issue, mainly in the cockpit area which will be making use of fiber optics. I have also noticed that the leads coming out of LED lights seems to be quite long. ...

Hi Ziz,

Not to worry, I didn't round off when doing the calculations; I just wrote that because I do not think one would go looking for/find a 3.6 volt power source!

Hi Ziz, Well, this is easier if one already knows what to do first.
