Arduino Mixture Control - Part 2

[Sabbadess]

Hi Wood Gassers,

I have been working on the automixer trying to be ready for the spring building season. My latest girl just left home for Nigeria so I am building my new Gas Station with the new automixer specifically in mind. I had to do three circuit board iterations because of a case of stupid involving the TO-220 component package pin out. I think it's all good now. We will see shortly. I have the latest board fully built up and ready to test. Here she is:

The first thing to notice is that it is labeled much more thoroughly. When I went to populate my first boards I was lost as soon as I pulled out the soldering iron.

Even after doing three iterations to get my board right, I would NEVER go back to bread boarding. I was a little afraid of the fine soldering but it was a piece of cake....far easier than connector wires. The only down side came when I dropped in an incorrect component and tried to desolder it. That proved to be impossible. Luckily the grate shaker circuit is the same as all the power sinks so it was no big deal.

Stay tuned for the test video.

Hi Wood Gassers,

Here is the new NSR automixer fuel/air ratio controller running a bench test:



I'm quite pleased with it(after I got over several cases of stupid).
