DIY: Build your awesome PC fan Tachometer in a breeze! Part 2/2

Once you’ve seen how you can measure the RPM of your PC fans in the part 1/2,
it was time to put the devil in a box!!!
I took about one month to me to design the smart clamp to catch the fans and deliver pulses to the main board. And then to also design the printed boards.
If I was to make this a final project, then the next step would be to move it in an Aluminum box with nice cuts for the DVM, power jacks and knobs.
Anyway, as it works pretty well and so many other projects are crying in line, I’ll stop the prototyping here.
So I reorganised the google drive folder in three distinctive sub-folders, like that:
Diagram folder: drive.google.c...
PCB folder:
drive.google.c...
In the Diagram folder, you have several versions of the schematic, including the one with troubleshooting stages.
This should be the one you try on a breadboard, before moving the parts on the PCB.
In the PCB folder, there are 5 files:
- The front mask suggested knobs arrangement
- the PCB components side, respectively
- the solder side PCB
- the wiring diagram from the 2, 3 and 4 pin headers to the front panel switches
- last but not the least, the PCB for the sensors clamp.
Finally, to help you building the sensor clamp, here are detailed pics:
drive.google.c...
It is a pretty detailed documentation for that little guy.
If you need any other help with the project, just drop me a line.
Cheers and thanks for watching. CU back to Logic Circuits next Tuesday!
