Resistor Board - Part II

I’ve been quite busy with work lately, so I haven’t made huge progress recently, but never the less, things are still going forward. I’ve added the leads to resistor board I built last month, so it will more easily be connected inside my control panel. A note however; as said in a previous post, I know this resistor board didn’t have to be built, but I did it to keep things organized.

One thing I realized however with adding the leads to the board was the large amount of extra wire that is required to do it this way (opposed to just having a resistor added directly into the wired circuit). With this system, leads need to come to the board to reach the assigned resistor, then must go back out to the component. This requires only more wiring length, so not a big deal at all. The added LED light on the board is for testing purposes only.

Resistor Board - Part I

Now that my control panel is mostly done, I’ve been trying to figure out the best way to layout the wiring inside to keep it tidy and organized. There are lots of individual circuits, so I decided to use a grid style PC board for the components, such as the bridge rectifiers and all of the resistors.

I realize that I could have probably cut down on the amount of resistors I used, but to keep the wiring as close as possible to my original plan, I opted to keep a resistor for each individual circuit. I’m sure there are a thousand different ways this system could be wired, however this is the one option that I chose.  I used my soldering iron to attach the components directly to the board. I will then eventually attach all my wiring to the back of the board to each appropriate component.
