In its June 2018 issue, the "audioxpress" magazine published my article about a Turntable Speed measurement device (as shown in the photo).
The device is based on a microprocessor ATMEL ATMEGA328-PU and was developed with Arduino software.
Due to copy rights I cannot post the article here but if someone has access to the article and wants to build the device I have some pcbs (as shown in the photo) and programmed CPUs for selling.
The price for both PCB and programmed CPU is 24 Euros (shipping cost is included in this price).
If someone is interested send me a message.

Maybe.
But we build something because it is a hobby and we enjoy it.
Sometimes it is not cheaper but much more enjoyable.

PCB and programmed CPU are still available!

I am pleased with this tachometer. I haven't found the phone apps to be very accurate.
Rpm pro is more accurate than strobe marks on the platter. Yes I verified that with 1000HZ signal recorded. Besides if you can tell the difference between 999.7 and 1000 HZ you better use that talent elsewhere.
The accuracy of my device is guaranteed by using as internal time base a crystal oscillator accurate to ±50 PPM (±0.005%) with less than ±5 PPM aging per year.
Joao Martins, Editor-in-chief of the audioxpress magazine was very kind to post on line the article for the Turntable Speed Measurement TSM-100 device.

My estimation for the cost of the parts needed to build the device is around 55 to 60 Euros.
Most of the cost goes to the LCD, the sensor, the high accuracy oscillator, the PCB and the programmed CPU.
A lot of the other components (like regulator, resistors, capacitors), I think can be found in every diy home lab and will reduce somehow the above cost.
If someone is interested for the PCB and the programmed CPU, send me a PM or an email at: gntanavaras@gmail.com

Unfortunately, the shipping cost has increased recently so the price for both PCB and programmed CPU is now 29 Euros (shipping cost is included in this price).

The sensor can be placed away from the PCB if that is necessary.
The signal that the sensor transmit to the PCB is of very low frequency and there will be no problem in this remote position.
