Buying a player up to accommodate for his food during his frequent touring on-Board generator. As the adapter decided to use a homemade solid state rectifier. The implementation of the ideas started by selecting a circuit diagram of the valve half-wave diode with a smoothing capacitor. Soon he was convinced regular Wellenreiter power 3-5,4 W and an output voltage of 6-7 V and the modified on-Board power grid using a rectifier for key any diode average power and capacitor µf 500-2200 quite cope with the new task. In the end, the player was to receive a 3-volt power supply when the Bicycle is moving at a speed exceeding 10 km/h with the included headlight and not less than 8 km/h is de-energized.
A more complex design that significantly improve the previous performance, was also performed according to the classical scheme, but with an “extra” diode VD5. Its purpose is when you drive at high speed to prevent a short circuit through the electrolytic capacitor, the properties of which increases as the frequency of the ripple current can straighten significantly
To bloginator such an adapter can be connected via plug / socket connector (for example, from an old radio). To the player, through the battery compartment thanks to a self-made tips substitute set of electrochemical cells.
