Joy. I had to login to PostImage then recreate a gallery for each photo. Once the gallery was created I was about right click to copy a link and the paste the link to my DIY Build thread.
Thanks, Ron

Note my Avatar. It is a Farmall H farm tractor. The H is a very popular tractor made by International Harvester in the 1940's and 1950's. I spent days herding one of these from when I was 10 years old until I was about 20 years old. My vacation was to drive my Grandfather's Model M which is a larger version.
Thanks, Ron

All, I have been googling to pin down the amount of current my four (4) Arduino's will draw. My understanding after the research is that the Arduino will take whatever amperes it needs and supply the balance to the output ports up to the limit of the barrel jack voltage regulator which is one (1) ampere. Therefore, I should fuse the 12 volt input with a 4 to 5 ampere fuse (one ampere per Arduino) to keep the voltage regulator from overheating. Arduino wants the voltage at the barrel jack to be between 7 to 12 volts. I plan to use an external regulator set the voltage at 9 volts. DC voltage converter Icstation 3.5 to 28 v to 1.25v to 26v 3a LM2596 x L6009 Amazon $9.60 $0.00 $0.00 $9.59
Thanks, Ron

All, today I want to share what I have learned about N- Channel Metal Oxide Semiconductor Field Effect Transistors (MOSFET). They are used for two simple functions. They can be used to switch or amplify a current. They have three pins. The first is IN called the Source, an OUT called the Drain and a CONTROL called the Gate. When you send a HIGH signal to the Gate the MOSFET switches and allows current to flow from the Source to the Drain. I plan to use these devices to control my DIYgasturbines oil pumps. The first MOSFET will act as a switch to turn on the first oil pump. A pressure regulator will be used to set the pressure of the first pump. The second MOSFET will be used with Pulse Width Modulation (PWM) to have a variable speed second oil pump which will maintain the desired oil pressure as the pressure regulator goes wide open due the oil temperature increasing. Originally I ordered a kit from Sparkfun which consist of a MOSFET, a resistor, a Printed Circuit Board (PCB) and two screw terminals. However, I discovered that while the MOSFET would handle the pump current the traces on the PCB would not handle the current. Today I ordered a DROK assembled dual MOSFET module which handles the required current. I will post more info on the module when I receive it.
Thanks, Ron

HI Ron,
I bought a Farmall Cub when I moved to the country 26 years ago (doing mowing and snow plowing chores on my 5 acres). The flathead 4 banger ran so sweet, it was unbelievable. She was replaced by a 4 x 4 Kubota diesel,,,but I do miss her.
Regards
Jeff

The Farmall Cub is a sweet little tractor. My father-in-law owned one when we lived in Upstate New York. I used it to grade my home lot when I built a new house.
I also owned a John Deere M when I had a old blueberry farm in New Jersey. A two cylinder Johnny Popper.
Thanks, Ron

Also, if you have undersized tracks, soldering over the copper will up the capacity, albeit by an unknown amount. Regards Dan

Absolutely the best possible solution for switching high currents. Here is a handy little switching circuit for general use. The optoisolator is optional, however I favour shielding delicate micro-controller from the dirty world of high current motors and solenoids wherever possible. postimg.cc/image/pw23fytzv/Regards Dan

A link to an image of the Drok BO1J78FX9S Dual MOSFET modules I purchased is shown below. I purchased two of these modules to control my Oil Pump # 1 and #2 12 volt DC motors since they can handle the voltage and current without any soldering. I plan to supply a constant 9 volt to the Oil Pump #1 Drok when it is initated by the key switch manually. If I start the gas turbine remotely it will be controlled by the Oil Pump Arduino Uno. Oil Pump #2 will always be PWM controlled by the Oil Pump Arduino Uno. postimg.cc/gallery/r2qspefu/Thanks, Ron
