I was cleaning up my desk (didn't get very far) and found an old Arduino nano, that I had purchased for a project. What project, I don't remember...I have a few of those around.
Anyway, the Nano is a small micro controller with several inputs, and outputs that can be programmed to do a variety of functions.
Arduino Nano (or at least a look alike)
There are thousands of example projects all over the internet.
After a little bit of searching, I came across a plan for a lightning trigger with just a few components. So, I dug through my piles of parts scattered on my desk, rummaged through bags and forgotten drawers and came up with the components I needed to start this build.
I did have to visit Amazon to pick up a cheap wired remote, and us that to house everything for now.
I received the remote Friday, and started working on preparing the switch to hold the wires and parts. I basically removed all the plastic ribs and mounts inside the handle, drilled out the button to fit the 10k potentiometer (sensitivity adjustment).
I did leave the standoffs for the screws to hold everything together later
A little solder, a few wires and the controller is ready to program.
Yes, all the wires are red
. It's what I had, and a $6 build didn't eat into my K-1 fund
. Besides, it is just a prototype build.
I still need a 6 volt power source though. (dig dig dig, scrounge ...) I'm thinking my wife will be donating a couple of those LED tea light candles
An extra cell taped on will do nicely[/SIZE]
Well, the tea light was spared, as I found a pack of coin batteries which I only needed the CR2025 size, and not the other two sizes in the package. I knew there
was a reason I bought the multipack
Packaging everything back inside the remote trigger handle
I did trial it on my K-5, with a lamp flashing on and off. Everything seemed to function as intended.
Now I need a thunderstorm or two to give this thing a try....
