Antenna Handbook: 04/01/20

Radio Straight or Crystal Radio for Science Project or Hobbyist



OA70 / IN34 / IN60 is Germanium Radio, choose only one type.
Antenna high from Ground is high is possible, ground is a must to Steel Water pipe, or making one from a piece of copper approximately 1 meter down to the ground, so will be voltage between ground and radio wave pick up by antenna.

I have build this Radio and connected input speaker to line input notebook and running with Open Lab software and can pick up Radio Signal from about 6 km air distance.

Sun Switch With Transistor 2N3055



2N3055 is Power Transistor and Amplifier Transistor for General Purpose and can act as Photo Transistor by cutting the "hat cover" of this transistor. This photo transistor function of 2N3055 can be taking the advantage as switching function with transistor. This circuit using 2 transistor which is 2N3055 and BD139. If there is no sun light or the light is not enough for Transistor 2N3005 to deliver, so R1 will give current to TR2 BD139 ,and this transistor will turn on Lamp on the Output of Circuit.








If The Sun Light which flows to "hat cover" of TR1 2N3055 enough, TR1 will deliver and will grounded Base of TR2 BD139 and will Turn Off The Lamp.R2 and P1 will improve switching system of the Transistors and The Light of Lamp Intensity could be regulated by P1.


At the below figure is Stripboard or Veroboard for the circuit. This Veroboard using DIY LC software.
