    Get power from RS-232 port

    The following circuit is an example how to get power from RS-232 serial port. It gives regulated +5V power for logic circuits and also unregulated positive and negative power supplies for RS-232 transmitting circuit. The circuit gives only few milliampres power output because the power available...

    Capacitane switch

    Take a look at the project I attach you: Wireless Liquid Level Sensing for Restaurant Applications It measures capacitance to determinate the liquid level of a glass and send the results wireless on a base station. It's quite interesting and i think you can take much ideas on how to convert it...

    Convert 0-30V 3A PSU to 5A or more

    Which is the relation between the number of the output transistors and the output voltage and current? If we put for example 2 output transistors in parallel, the output current we can draw is doubled (theoritically if the rest of the circuit can affort it)? shall we change the rectifier diodes...

    Hameg HM205 Oscilloscope Manual

    Yes it is a good oscilloscope, but it is around 20 years old.. so there must not be an electronic version of the manual.. If i find it i will put it to the site! I have already e-mail manufacture.

    Convert 0-30V 3A PSU to 5A or more

    I measured the AC voltage across the transformer at 1V/3A the output was a distorted sine with 32V amplitude and it goes till: 1,4V/4,4A where the output was also a distorted sine with 31V amplitude Is the transformer goes to current saturation? At these outputs except the Q4 also the...
