–The heresy of PVC pipes is the orthodox of ham radio–
This time, I came up with the idea of storing the entire rotator mechanism inside the VP tube.
Vinyl pipes are a standard item for handmade amateur radio antennas. Wire antennas and Yagi antenna loading coils… Horizontal support material for 6m Hentena… Spreaders for Cubic Quad… I have used this cheap, easy to process, and fairly durable material a lot.
However, what they all have in common is that they were never used for their original function of passing something through them. “Use the surface or use it as a structural material” – that was the “royal way of using PVC pipes” in amateur radio. In the amateur radio world, which deals with electricity, water is now our fate and our nemesis. Therefore, PVC pipes are never treated as something that passes through water.
These pipes are born into this world and line up in the hardware store with the noble goal of “helping people who need water.” in his heart (Could you tell me what part of the pipe is the heart?)
However, once pipes fall into the hands of an amateur radio geeks, contrary to their goal, they are used for an unintended purpose, drilled holes, cut, or tied up with copper wire…
I have been treating them like this for nearly 50 years now.
It’s not just pipes, it’s the same with fishing rods. I’ve bought 20 or 30 glass rods…but I have never attached a line to any of them and dropped them in the water.
So, this time, with repentance for all those reckless misdeeds, I will undergo the penance of threading a pipe. … Will I be able to succeed?
Enough with the digression. I lined up the motor and battery.
It seems the maximum diameter is about 15mm… ”If I put it in a VP20 with a little margin, I can attach it to the rear base of a car and turn it?” I’ve settled on the idea like that.
The picture shows two nickel-metal hydride batteries, but the control circuit I’ll assemble later is 5V standard, and I’ll be using the green microswitch in the picture to assemble a limit switch that stops the rotation angle at 180°, so a diode will be included in the power supply line, causing a voltage drop of 0.7V, so in reality I’ll need four batteries to make it 4.8V.
Even with the G5V switching relay mounted on the universal circuit board, somehow it seems to fit within an inner diameter of 20 mm. There remains little space as in a subway tunnel.
