Building the AADE LC Meter

  Building the AADE LC Meter Filed in Kits on Mar.06, 2010 There is a really nice Inductance/Capacitance Meter available from aade (Almost All Digital Electronics). This is the AADE L/C Meter IIB. It comes as a kit and takes a couple of hours to build.  When you are finished, you have a nice tool (rather than the kludge I had for capacitance before) that can read .001 to 100 mHy (most units measure to 150 mHy), and .010 pF to 1 uF (most units measure to 1.5 uF). It is auto-ranging, and has a one-button calibration feature.   First, a look at the Kludge I had for capacitor measurement before this:   This was built from an old ARRL Handbook Circuit.   This circuit worked OK, but required a VOM for the display, and a “reference” capacitor for calibrating on each session. Now that I have the AADE meter, I can reuse the nice hardware from this box for future projects. Now on with the AADE Build: Here are the parts straight out of the bag:   First, I sorted the parts, so that the

MMR40 – Finished… For now

  MMR40 – Finished… For now Filed in homebrew on Mar.06, 2010 Ok, I’ve spent enough time on this one project.  Once again, I couldn’t make it perfect (and that drives me crazy)… but it’s time to call it finished. The final touches involved a little chassis work.  A few coats of paint (but I was too lazy to fix the existing scratches in the top of the case)…   There was a large hole in the side for the orginal CB microphone.  I covered this up with a piece of perfboard glued to the chassis inside the hole. It was painted black to make it less visible.   And finally, some stick on rubber feet were applied to the bottom.   I don’t know if it is the lack of AGC, or what, but I really like the sound of this receiver.
