@NeverDie said in Highest efficiency LED?:
flashing an LED for 5 mS to 10 mS is quite noticeable.
I checked in an old sketch for a board that was using a 0603 green led (cheap one so not even bright light) and I had a 20ms on time. But this was producing quite a strong light flash, easily noticeable in daytime through 2mm of white PLA (battery was CR1632 and resistor I think around 2K).
I think it's a combination on "on time" and the current the led receives, so you will need to experiment with the leds you buy, the "problem" is not really about a duration but of a quantity of light you manage to get from the LED compared to ambient light.
I don't know if you saw the answers to this question, but the experiment is quite interesting.
@rmh said in EV Charger (type 2) with RESTful API and Wifi recommendations?:
@รอเร-อ btw Normal single phase type 2 charging on an EV is 32a = 7 Kw. If your ev can charge at 22Kw, then it will need a 3 phase supply. OpenEVSE can do this but you will need to put a 3 phase contactor in it.
Thanks a lot. That seems to be exactly what I'm looking for. I didn't order the kit though. I ordered the EmonEVSE WiFi Connected EV Charging Station IEC 60947-5 (Type-2)
I'm very excited to get started. Ohh... I'll need an EV too... ha ha
@timmy If you are referring to the Google assistant, you need to open the app, tap the compass icon in the Explore section, enter Settings, scroll to Services, tap Home Control, and scroll until you find the selection for your lights. But I'm not even sure what you are talking about, I might be giving you the wrong directions here.
