Archer Project Board Power Supply
This board provides 5 volt or 13.8 volt power. may be built up as a 5 v/13.8 v dual power supply. This board has LM317 and make a nice Laboratory bench supply. Thanks...

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 a single digit voltmeter. This circuit is a design,...
Here is a easy to read ‘Analog’ Millivoltmeter. Just like the Moving Coil Voltmeter, but does not have that resolution. This gives a easy indication of process progress or parameter magnitude from a large...
Question – i want a continuity tester circuit or get one. mail by RB Here are some pages that might help Simple Component and Continuity Tester – This simple project may be used for testing components,...
This indicates like LM3914 in dot-mode. It is a drawing i made made to troubleshoot a gadget, around two decades ago. Strangely it had a echo of a design i had made into a...
