What did you create today?

[petertub]

A fuel sensoring device built around an arduino AICHI (oval gear) flowmeter.
Displays on top row liters/h, liters since start
on botton row total running time and total consumption.

I used to get to measure flow when I was employed. Mostly air. Later # of product picked and placed in a tray, but that was just for fun, as they knew already.

The worlds only pair of Elac LS70 II in 50 cm height in Fenstergrau RAL Siebzieg Vierzieg. Powder coated of course.

And an eighties Target audio rack in the same color.

I think they are wunderschön.

Fuel sensor mockup testet in a petrol boat. Problems until we noticed that emissions from the ignition system
was creating false signals. Then it worked as it should. Next will be hf filters at a couple of places and a
more permanent encapsulation.

Victor’s 1 kHz. ultra low THD sinus generator in a box, fed by a XL6009 dc-dc step-up board (35 VDC) and a 9.5 VDC wall wart.
It works with a 9 Volt battery as well, I just checked!

Measurements now show the THD of the line input of my Steinberg UR242 external USB audio interface…
