I wanted to design a logic probe as a tutorial, but there were many good ones in the web so i have tried to design […]
This is a modification of a mV Source that can be whipped up easily. You could use a DPM or Multimeter to read the output. […]
U3 LF 356 is used as a constant current source (sink as the current is negative). R4, R5, R7 and R9 set the four resistance […]
Here the 4053 selects or routes the voltage, current or resistance measurements to the A-D converter or display. It is selected with the mode selection […]
R6 is the Shunt thru which the current to be measured passes. F1 fuse is to protect shunt. D1-D4 ensures that the current flow is […]
