Description: This kit includes everything you need to make your very own capacitance meter, able to measure caps anywhere between the range of 500uF to 1pF. Many multimeters are able to measure capacitance, but they’re rarely as precise as a dedicated capacitance meter. Not only does this product provide a great chance to hone your soldering skills, but you also come out with an accurate, fully functional, capacitance measuring tool.
Assembly is very straightforward, and all components are through-hole. You’ll get a chance to solder a wide range of components such as resistors, seven segment LEDs, a 28-pin ATmega48 microcontroller, and more!
An 8-16VDC power supply is required, but not included.

I bought this on a whim just to see if it would actually measure capacitance levels as well as and below what my WaveTech multimeter does. Surprisingly, this unit does indeed measure the capacitance values quite well. My WaveTech didn’t have the resolution (needs another digit) to show me anything like the 22 pF we use on our boards. This one does it well!
The assembly is easy and straight forward. Some hints: A) Make sure you have the polarity on the electrolytic capacitors correct. You might want to use an ohmmeter and reference the schematic to make sure you know where the +/- side is on the board. B) I would suggest you measure all those resistors as you insert them in the board. The color bands are very small so I immediately got the ohmmeter out just to make sure.
Once you have it assembled you may ask: how do you keep it away from all that “conducting” stuff on your workbench?
I found that it will fit very nicely in an Altoids tin. Cut a durable piece of plastic the shape of the tin and place it under the capacitance checker. Drill a hole in the tin for the power socket and it will be protected from inadvertent contact with conductors on the desk. You can still close the cover of the Altoids tin when the capacitor checker is in the tin.
Another thing I found it will fit in is the hard rubber molding for the Iphone-4 sized protectors. If you slide the end off that molding you can slide the capacitor checker into that unit and it will not fall out. This method does not provide a cover however.
Easy to assemble, gives accurate results. Very handy for measuring the capacitance of those mystery caps in the junk box. The numbers can be a bit hard to see if your work area is brightly lit though.
This kit is great for anyone that wants to get some soldering practice building a useful piece of tech for their workbench. I will note that while the parts list claimed 1% tolerance on all resistors, most were 5% tolerance, which may cost a bit of accuracy. Would be interesting to build another kit with all 1% tolerances to compare readings. All in all, a useful addition to anyone’s bench.
It works great except the last digit on right misbehaves. I am going to buy a box and put it in. Thanks. Victor
I carefully built this kit and found that it does a very good job of measuring caps. I might want bigger holes in the measurement terminals. I did goof the polarity on the filter cap and had to replace it. However, that was my bobo. Measuring and sorting the resistors is a must before putting them into the board. I handled the unwanted electrical contact problem by covering the underside of the board with some stick on fun foam from a craft store. Recommended.
