Not just any counter, a classic Hewlett-Packard 5350B Microwave Counter. recently got himself a frequency counter.

That’s a win in our book.Ĭontinue reading “Nanocounter: Frequency Counter With An Android UI” → Posted in Tool Hacks Tagged android, bluetooth, fpga, frequency counter, TCXO XOXO For The OCXO
( Classic yak shaving!) But the result is a great read of a detailed writeup, and you can watch a video of the Nanocounter in action after the break. The project achieves the goal of frequency counting, though doesn’t remember what project sparked the idea to build it.

Finally, a cheap HC-06 Bluetooth module facilitates communication with an Android device. A STM32F072 microcontroller uses a SPI interface to get this data out of the FPGA, and controls the whole system. This reference clock, along with the signal to be measured, are sent into a Xilinx FPGA which uses a method called equal precision measurement to determine the frequency. It’s based on a high accuracy temperature compensated crystal oscillator (TCXO) fed into a phase locked loop (PLL) to create a high frequency, accurate reference clock. The Nanocounter is an accurate, open source frequency counter that uses an Android phone as its display. Most people would just buy a frequency counter and be done with it, but decided to build his own. Plus, no worries about airspace access, if you live somewhere with enough population density to necessitate automated car counting.Have you ever started a project, run into an issue, started a new project to solve the issue, and completely forgot about the original project? went down a rabbit hole of needing a tool to calibrate an MCU oscillator, but not having an accurate way to measure frequency. Otherwise, it doesn't sound like you already have a drone (or a 107), so those two items alone will get you to $400. For $400, have a purpose-built equipment. There's already fit-for-purpose hardware for this application - those rubber tubes laid on the ground. Unless you're Lakewood Church or something. But until you're into the 1000s of cars, this isn't a great ROI.

You *might* be able to get a drone up, capture an image, offload that image, then run some software to count the cars on a weekly basis. This problem basically has two steps as you want to tackle it:ġ) acquire imagery from above parking lot at desired time (Sunday)Ģ) count cars on imagery (automated or otherwise)įor a quick return-on-time calculation though, what's the ballpark of cars you're counting? If this is a 30-min activity every Sunday, you can count ~ 880 parking spots walking. I don't know of any out-of-the-box drone that already has software to recognize a car. There a thousand more detailed considerations you could look at but hopefully that gets you unstuck for now.

Do not buy equipment or software until you have a full plan for everything.
