DIY Frequency Counter Kit, 0.45Hz-10MHz Frequency Meter, Frequency Counter, Digital VR Frequency Meter, Measurement Making DIY Kit, for Home Industry

This is an excellent product and currently at a very reasonable price. The quality of the PCB is excellent, as good as any used in professional equipment. The Meter comes as a kit, and components need to be soldered. The number of components is not large but some soldering skill is required, but with a bit of care it can be done easily and quickly even by those with only elementary soldering skills. I used a soldering iron with a pointed tip and run it hot (400 deg C) so that the solder melted quickly, minimising each component exposure to heat. I used thin solder wire (about 2 mm diameter). The frequency Meter works very well, I tested it up to 100kHz, and a quick comparison with another frequency meter (different make) showed that it was reasonably accurate. The red switch toggles between measuring of frequency to measuring of period in microseconds. The transparent case is easy to assemble and is held together with four of the screws provided. All in all an excellent product, currently at a very reasonable price, and I recommend it.

This is the second one I've built, the first one went bang... entirely my faultThis particular one has three more digits above any other on sale of a similar type so I decided to try again and was successfulPretty accurate frequency measurement but the extra digits are a gimmick really, it's not accurate to that resolution 😂

I loved the look of this module. It’s elegant engineering saying more about the care that went into designing it than the finished product promised! I’m afraid, on assembly my kit did not work, perhaps one day I’ll try again? Unfortunately I don’t think it was my error that jinxed it but some error in the program code!

Now it won't do anything, something in it has malfunctioned, disappointing.
