Summary

Speed Strobe for adjusting Turntables at 33 und 45 1/min.

Way cheaper as the bucks, the HiFi Industry want to see from you.
(Let's say if you bought expensively, about 10 to 12 euros (compared to 50 to 100 euros in "Jeff's warehouse" or around 30EUR at other sellers))

In this version 50Hz, so, you need to print or buy a strobe disc for 50 Hz or if you own one for 60 Hz, feel free to change the Arduino Code.

A nice printable one, the one of the short video, is:

(In the gif, it looks like an inconstant light, thats only because the frequency sometimes dismatch the single picture frequency. In reality it looks like a nearly constant light (in 50Hz))

Screws:
You`ll need 4x M3x8 or x10mm screws and 2x M2x 6 to x8mm screws, one M4x25mm screw and a M4 nut.

Battery / Akku:
9V block

LED:
Green one (better to see than other colors)
with resistor
(I have had only the 10 to 20V version at home, you should use a version for around 5V with an other resistor to have a better brightness. But it is ok with the one I have had installed.)

Button:
Tactile button / PCB Button / Arduino starter kit button / momentary switch

The one from the Arduino starter kit....
I didn't have a better switch at hand and the stupid little thing had to be installed. Sorry (Feel free to remix it new! ;-))

1x Elastic band or TPU filament for the Trigger, but it works with and without and works without trigger, only pushing the button, too.

You can solder the wires or crimp it. For me, I was in hurry and crimping was faster.

I take no responsibility for any problems with the code or design.
It is a DIY handicraft object that works very well for me and has no claim to technically correct electronics or construction.

P.S.:
I printed the bottom part in from the slicer generated segments and used glue for the handle, but with supports, I think it will be no problem to print, too. (Minimum changes of the unmixed part.)
The parts were mixed in Fusion as a STL net structure to a solid part, therefore, it will be possible to optimize it in terms of design and printability.
Unfortunately, I don't have time for this at the moment, a functional placement of the board was enough for my needs.
