My more preferred hobby is the computer. Each time I sit in front of the computer I learn myself something new. Who wants to know well the computer must devote much time to carry it out. My second hobby is dimenssionnement and the realization of the electronic assemblies. I present some assemblies to you which I carried out durring the last years. - Mini Equalizer (This apparatus must be connected between the preamplifier and the amplifier) - Amplifier for Guitar, - Power supply unit, Rated current = 2,5 with an adjustable output voltage of 0 - 30 V - Stereo switching box This box makes a switching of stereo output signals of the sound card of the PC between the PC loudspeaker and the Hifi plant so that you don't need anymore to change it on the back of the PC - Power Amplifier (Mos-Fet-Technologie) With an Output power of 100 W, it can be used for small apparatuses of music. To get more Output power, the plan must be dimensioned differently. - Dim potentiometer Using a triac and other electronic components, this apparatus can regulate incandescent lamps until a power of 100 W; the voltage varies between 7 and 230 V. - Mini Amplifier Very well for small apparatuses of music and also for electric guitars. - Sport Im Summer I make bicycle or I run almost everyday after work.
