Build a variable speed control for trolling motor

So today I built a variable speed controller for my #minn kota endura c2 #trolling motor (changed from forward 5 speeds and reverse 3 speeds to infinitive gear) using #PWM (pulse width modulation) technique. I also connected it to a 4-in-1 volt, amperage, watts, energy #meter to show how the current is being drawn when I switch gear.


It allows the battery to run longer because the amperage drawn is more continuous than vertical jump when I switch gears in 1-2-3-4-5. Now, the gear is changed from 0-0.01-etc. it is controlled by a dial button on the PWM. so i get infinitive gears, hence a more smooth amperage.

check out my PWM variable speed control video here - hhttps://www.youtube.com/watch?v=yGoYmJ81xrs

My next video is to build a variable speed control for my foot controlled motorguide 70 pound push motor with 24 volts battery.

Lake Anna boating and fishing on Saturday 10/11/2015

Got to the lake anna state park around 1pm after fighting through tons of traffic on Rt 95 going south. It was supposed to be an hour and half but it took us 2+hours. We hiked 2 trails when we got there. The 1.6 miles round trip Railroad ford trail along the lake next to the beach, and the 0.3 miles Old pond lake behind the visitor center. The morning weather was kind of cold and cloudy, but the sun started to show its face after we got to Lake Anna. The temperature started to rise to about 70ish, so it was a very nice warm afternoon. Amazingly, little to no wind, so it was a perfect afternoon for boating. Very very calm lake.

We found ourselves a picnic table under the shade and had our picnic sandwiches. It was delicious. The lake was calm and beautiful. It was the million dollar view and enjoyment but at just a few bucks door entrance to the park. We then went to launch my boat - wellcraft airslot 165 sport. We trolled for fish all the way to the visitor center on Rt 208, but didn't catch anything. So, we went past the Rt 208 bridge and sped home to the dock. We saw 2 fishermen fishing in the middle of lake so we stopped to join them after finding tons of stripe bass (my guess) in the fish finder

Hummingbird 200 DX. We didn't have any luck either after 20 minutes we called it a day and headed for the dock.

My starter was not engaged until 4th time after I opened the cover. Thanks God, we started the motor and just head straight to the dock. A very successful boating afternoon. I found my trailer light line broke, so we were hoping to rush home before dark. We got to tyson's corner in VA and pulled over by a state trooper. He asked for my license and told me my truck tail light was dark, and the boat trailer had no lights either. Bummer, I thought I was going to get a ticket. He asked me how long did I have to go? I said 1 more exit. He asked me to put on the emergency lights and he let me go. He said to me he was supposed to call for tow so I thanked him for giving me a break.

What a lucky day!

sandy point state park boating - a very calm and super beautiful sunny with blue sky day


I checked the wave forcast and it is less than 1 feet of wave with marine forcast and sunny day, so took my wellcraft sport airslot 165 boat on my venture trailer with my Johnson 90 hp v4 out to Sandy point state park. It was a gorgeous day in the Chesapeake bay. I saw sea gulls floating between the lighthouse and the sandy point state park beach, so I headed towards the  lighthouse.

They are doing construction on the lighhouse, but I didn't see any workers working on the lighthouse? Very interesting? Today is not weekends, so not sure why nobody working on the sandy point shoal lighthouse. Got to the ramp around 12 noon, had a nice omlet (2 eggs with lots of vegetable) breakfast.



Left around 10:50am no traffic and very smooth ride to the sandy point state park. Launched around noon, and got around the lighthouse and went fishing very briefly under the Chesapeake bay bridge. The Chesapeake Bay bridge is as usual, you can hear the cars, trucks roaming above the bridge. It is kind of noisy to fish under the bay bridge. I am surprised that I didn't notice it the first time when i went there last year. I guess I was overly excited to be fishing from my own new boat - LOL


Finished the boating around 3:15 pm and headed home. As usual, I hit the beltway traffic and got home around 5pm. Another successful outing with my boat and Johnson 90 hp v4.
