Skema Rangkaian|Electronic Schematic Circuit Diagram

With the circuit shown here you can create high frequency electromagnetic waves with very high output power.

Possible applications are experiments with wireless power transmission, RFID Transponder, tesla coils and the like.

Dependent on the coil, capacitor and cooling of the transistors output power in the range of 20W and more can be obtained.

At short distances, other electronic circuits may be disturbed or even destroyed. Broadcasting, RFID, AntiTheft, Wlan, medical appliances (pacemakers!) can be disturbed in a large area!

Never operate this circuit without taking precautions !

It may be illegal to operate in your Country!

Many DIY projects require a small Power Supply.

The 78XX family is ideally suited for this job, and with this little PCB you can easily build small Power Supplies for virtually every application.

The circuit is very simple:

The Alternating current is applied to X1 and rectifies by B1.

It charges a large Capacitor C1 to power the regulator.

The output voltage depends on the Regulator you use, e.g. 7805, 7812,7815…

Dimensionierung:

C1:4700u, with sufficient voltage Rating!

C2:0.33u

C3:0.1u

The Heatsink should be enough for devices with moderate power consumption.

When experimenting with tube amplifiers, you ability be abashed about the altered modes of operation, like triode or pentode mode. To accord a little advice i developed this PCB. You can body baby Amplifiers based on 6P14/6BQ5/EL84 easily, and the achievement Power of 2..6 Watts is added than abundant for home use.

With this PCB you can try out the altered Modes by agency of Jumper Wires.

The Schematic is actual simple:
