I've been messing around with PWM for audio on the original ESP32.

I love technology.

When I'm on my couch, the #PWM dimming of the #Hue LED lighting makes my #Fitbit believe I've got a >200 bpm heart rate.

This is all great and well thought out.

As much as I like #Armbian, the fact that it does not start the PWM fan of my #nvidia Jetson Nano device is a serious problem during the summer. 🥵

My device already overheated and shut down today. Only workaround I found so far was to throttle #CPU at 50% max speed, which for now keeps the system stable at below 60°C, but is far from ideal.

Anyone who knows how to get the #PWM Fan working, please talk to me 🙂

Przygotowania do #Wyprawa2023 🚲 #rower

Zasilanie to podstawa, bym mógł pracować w trasie. Przymierzam panel, badam kąty przed ostatecznym wierceniem w przyczepce i montażem.

Zamiast stacji ładowania własna konstrukcja: akumulator żelowy, niedrogi kontroler solarny #PWM i rozdzielacz gniazd zapalniczki 12V.

A na koniec dnia zabezpieczam całą przyczepę przed deszczem.

To będzie długa podróż 🚀

Zdjęcia z różnych telefonów z 2 dni, sorki za jakość.

Chętnie przyjmę pomysły o zadaszeniu takiego zestawu, myślałem o przyciętej w trójkąt plandece :)

#DIY #zasilanie #fotowoltaika

Pod panelem fotowoltaicznym, z tyłu przyczepki pojemnik z akumulatorem, solarnym kontrolerem ładowania i listwą z gniazdami zapalniczki.
Przyczepka z panelem fotowoltaicznym pod szarym pokrowcem. W tle rower. Wszystko w ogrodzie, dookoła zieleń, krzaki, stolik z ławeczką. Świeżo skoszona trawa.
Na biurku przed otwartym laptopem akumulator żelowy 7Ah, solarny kontroler ładowania i listwa gniazd zapalniczki a w niej jedna wtyczka od lampki i urządzenie wielofunkcyjne: ładowarka USB, bluetooth, player z SD card i nadajnik FM :)
