How to know SMD Capacitor value.? because no any value on it.

The smarttweezers look really exciting! I loved everything about them.

Until I got to the bottom of the page - $314!!

I would be severely tempted to make up my own "semi-intelligent" tweezers by modifying some real tweezers with glued-on insulators/handles and large sewing needles for points, leading back to wires which plugged into a more modestly priced LCR meter.

Tenma makes this one: http://www.mcmelectronics.com/product/TENMA-72-8155-/72-8155 and MCM electronics sells it for $59.00. Harbor Freight sells this tweezer set: http://www.harborfreight.com/hand-tools/precision-hand-tools/4-piece-tweezers-set-32381.html for $6.00. The first two on the left in the set look like good candidates for making into a set.

With a little ingenuity, the probes from the LCR meter could be arranged to plug into the top of the tweezers.

Hmmm. RATS! Now I have another project to do.  ARGH!!

No markings at all or just no value?
New and exciting innovations in current technology!

No worries R.G., Tenma already makes a $40 diet version of the Smart Tweezers, http://www.mcmelectronics.com/product/72-8485  ;)
