|Have purchased an Ender-3 3D
This is totally new to me, but this was very easy to get to work.
Drawing program is the free program DesignSpark Mechanical.
The program that generates the files for the 3D printer is Cura 3.6.0
CD ANTENNA WINCH
CONNECTOR FOR AN/VRC-12
I have more radios than I have mounting frames.
I have therefore designed this powerconnetor.
The first attempt was perfect.
I use gold plated contact elements from other contacts.
CONNECTOR FOR WW2 GERMAN RADIOS.
Here I print the prototype.
It is not easy to design a good contact that can be used for a long time.
Here I mount the cable
Here the prototype is tested on a Torn.E.b.
|Here I have made corners for a small box.|
This is half the coil. Must be printed twice.
|This is my first design.
RF coil form.
|11uH, L=49mm, D=49mm, n=19
|My second design.
10.5uH, L=50mm, D=60mm, n=16
|I am very pleased with this
result after only one day.
|I have designed a coil with
It is intended for a tube transmitter.
The outer coil is for the anode circuit.
The inner coil is for the antenna output.
Outer coil: 8.5uH, L=52mm, D=64mm, n=14
Inner coil: 1.6uH, L=17mm, D=50mm, n=5
turbine made from beer can.
First test of the wind turbine.
Wind turbine top part.
Wind turbine lower part.
Now it is finished and painted blue.
Double wind turbine.
Two sections with 90 degrees rotation.
A 4.5mm knitting needle is used as a shaft.
A drill must be used to make holes.
