What I know about electronics I could put in a thimble but have decided to learn enough to get me by. This post is probably premature also, as I need to open some more books, but someone here might give me some direction?
I dink around with out of production pellet stoves a bit and have adapted boards from manufactures still in production to stoves that are not. They usually work fine , but involves considerable expense as the manufactures are proud of their electronics. If the boards were made in China, they would be 5 bucks, but run anywhere from 160-350 without the harness which is another 60 bucks. Most of these boards can be repaired, but some need changing to allow modification of design flaws of the original applications or voltage changes etc.
What my ambitions are at this point is to build a simple board just consisting of a stoker control that would run the auger. This would require a timer, the correct relays with a duty cycle that would hold up to firing every few seconds and learning how the timers are plumbed. Different boards use different timers. One board sitting on my desk in front of me uses a 556 dual timer ( two 555 timers in one enclosure). Why 2 timers, maybe to shorten the firing time, I don’t know? Another board sitting here appears also to have two timers if those are actually timers I am looking at? The working board with the 556 timer is simply constructed and controls more functions than the other board ( which is toasted) and looks like someone's combination pizza. I guess there is something to be said about simplicity in design?
Where do I go from here? First I need to learn how to identify all the components on the boards, timers, relays etc? I know some basics, but a lot of this stuff looks foreign to me.
Possibly someone on this forum knows about timers relays etc and their application and can point me in the right direction?
Thanks for your time,
JB
