The AEMBLINK is a board with a polycrystaline solar panel, AEM10941 solar harvesting PMIC, and a ultra low power LED blinking circuit based on Texas Instruments TPL5110. It features an 1.8V output to power your application with, for example a Bluetooth Low Energy Module. There is about 13x19mm area unused area on the board.
Why did you make it?
I designed it because I am already selling this and this solar harvesting boards and this time I wanted to design a cool gadget with ultra low power blinking circuit.
What makes it special?
it charges in just 5 minutes of full sun, at 800W/m^2 solar irradiance
it blinks for at least 8 hours, tested on 10 devices
it harvests enough energy from indoor light (200 lux) to maintain blinking. It seems to work forever.
The LED blinking circuit is ultra low power. Average current is ~10uA. The LED pulses are only 14ms long, long enough for our eyes and brains to perceive at full brightness and they have ~2 seconds blink interval, short enough to strongly draw attention. Highly efficient LEDs with large viewing angle were selected.
the PCBA is wearable, light enough for an earring, but it can also be worn as a necklace or a badge
