Interestingly circuited actually zener diode test measuring instruments should have a property zener measurement of when you are secure, a voltage see better, but so far no measuring instruments equipped with this feature I have not seen though the circuit design a separate beauty measurement probe to be in shape to use is easy. Zener test circuit for ATmega8 microcontroller based on the indicators used 2 × 16 LCD also very practical and clever Inbox big thick felt-tipped pen used.
Circuit visionav source code of the code sprint pcb layout (zener_tester.lay) file spline scheme (zener_tester.spl7) and there are pictures about insurance options.

USB Powered Charging Circuit 5V
Mobile phone, mp3 player etc.. many devices can use a simple charging circuit .. circuit 7805 on the regulator board if direct 5v if you are arriving 7805 no need to use only USB Data-“D” and the Data + “D +” connected to the ends of resistors need to be
iPod for charging USB Data-“D” and the Data + “D +” for other devices will be 10k 100k resistor will be
