Tauno Monitor

I have released a new version of the serial monitor application “Tauno Monitor” for Linux and added a “Clear” button and timestamps display option. The goal is to keep it simple and minimal.

Profiiil

Mingil põhjusel meeldib mulle maalida inimeste profiile.

The Breathing Light PCB board

The biggest PCB I’ve ever designed has arrived. And all RGB LEDs work as planned. Manufactured by JLCPCB. The diameter is about 260mm. It is still necessary to make the body and finish the firmware.

My photocoupler (optocoupler) board design. I added four resistor places to combine them with different input and output voltages. Also added a diode for reverse voltage protection. Does the output side need it? Any other suggestions?

Updated version

Update version with a two-way communication.

Biovälja spektrograaf

Andur mõõdab kehalt tagasi peegelduvat infrapuna (IR) kiirgust ja arvutab selle järgi pulsi sageduse. Samuti amplituudi, kuna on rõhk kõige kõrgem ja madalam, mida kajastab vastavalt põlevate LEDide hulk. IR väärtustest arvutatakse ka LEDide värv.
