The Harvester: ultimate power supply for the Raybeacon DK:
The current limiting resistor between the SPV1050 and the tantalum capacitor has been removed
Why removing the resistor? Why not placing it after the (optional) Tantal to protect a downstreamed Batt or Cap?
@iiibelst
ok, seems to be possible, because it is 10x the area of ECS300...
Looks good, I am wondering about the high power, cannot imagine 
because meanwhile I tested the ECS300, used in Enocean products, also designed for low light (200 Lux) with amorphous crystalline cells. But the MPP is only about 160µW @ 1000(!) Lux.
Hi, i am actually building a similar PCB for Energy Harvesting with SPV1050. What about the 196 HVC ENYCAP
from Vishay like MAL219691262E3? Seems for me as a good Super Cap with acceptable dimension...
