Farm Electronics Maintenance

Last weekend I replaced several of the DC-DC converters in my solar powered surveillance system.  Extended time in the extreme temperatures of their housing had made their predecessors less stable and less efficient.  The final straw came a few weeks back during a massive lightning storm.  I suspect the lightning had induced current in some sensitive components within the devices.  Anyway, after that the system seemed prone to frequent reboots, which was annoying.  
Before installing them I had to spend some time studying the data sheets and then soldering the connectors in the right places. The above photo shows the converters ready to go.  
Then I installed the new converters one at time testing each one for correct function at multiple points along the way.  The result of this replacement has been improved proformance of the system which mean more reliable updates about the bison.  
 In other news the bison mating season began about a week ago.  This is indicated to me by the tendency of the dominant male to softly growl at whichever female he is courting.  To the bison it's probably more like singing, but to me it sounds like low frequency growling. You can see the bull in the above surveillance photo (center-top) standing immediately behind a female.

Front-end loader mounted t-post installer

Image
 Since we started fencing the perimeter of our ranch in 2014, I've strove to increase the rate at which I am able to fence an area.  Among the most recent improvements has been a t-post pusher which is mounted to our tractor's front-end loader bucket.  This device is very simple, but has already saved us countless hours of work. The following photographs illustrate how I use the post pusher.  Aiming: The loader is first positioned with the end of the pusher is close to the ground.  I then maneuver the tractor until the end of the pusher is in alignment with the marked post location.  This is how the lined up pusher looks from the driver's seat of the tractor.  Yes, I know the loader has an issue with the hydraulics cover. Loading:  Once the pusher is aligned, I place the tractor in park, raise the loader arm and insert a t-post into the open end of the pusher.  Tilting:  Correct placement of the t-post is dependent aligning the post along three axises,

DIY cultipacker-roller

Image
For those of you who are unfamiliar with agricultural equipment, a cultipacker is an implement used to compress soil.  There are several reasons a farmer may use a cultipacker, but, for me, the primary purpose for the cultipacker is to pack down soil that has just been planted with grass seed.  This should greatly improve seed germination in newly planted bison pasture. Five truck tire rims welded together form the shape of the cultipacker.  Technically this is really more of a cultipacker-roller hybrid as the ridged portions on the roller should be more closely spaced on a true cultipacker.  A thick piece of steel tube runs through the center of the rims, which I'll explain later in this post. For added weight each tire rim was filled with concrete after it was welded in place.  A photograph of the roller portion of the cultipacker completed and waiting for the concrete to cure.  The length of steel tube that runs through the center of the roller is welded to the

Face fly nightmare

Image
Face flies beginning to appear a few days after my initial treatment with AiM-L VetCaps.  I unfortunately don't have any photos of the original mob of flies, which was much worse. Since the forth of July an insect called the face fly ( Musca autumnalis ) has plagued our ranch and caused me a considerable amount of stress.  It was a week ago, on the forth, while doing a routine check on the herd, that I noticed that the bison appeared to be greatly agitated by a surprisingly high number of the flies.  While the sight of flies or other small insects buzzing around grazing animals is nothing unusual, this was something different.  The flies flocked in groups around the eyes and nose of each animal so incessantly that the bisons' natural defenses appeared to be ineffective.  All the blinking, ear flapping, tail wagging, snorting, rolling in soil, and rubbing on trees had little effect.  No matter how many times they did these things the flies would just briefly fly up into the
