Üks LED valgusti 15 LEDiga. LEDe juhitakse läbi WS2811 kiipide, mis lubab kõikide LEDide heledust kontrollida individuaalselt. Tahaküljele saab kinnitada ka Seeedstudi XIAO arendusplaadi. Või siis kontrollida eraldi oleva mikrokontrolleriga. Mina kasutan siin ESP32te. Neid valgusteid saab ka järjestiku mitu tükki üksteise järgi. PCBd valmistas ja printis PCBWay. Komponendid jootsin ise. PCB läbimõõt 10cm.

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.

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.
Photocoupler PC817 circuit
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.
