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.
