Adapted Pi-Top for solar panel by replacing display cable outlet for DC cable
03/20/2021 at 13:17 • 0 commentsWas able to fit a 5" screen in Pi-Top v3, thus considering use as a cyberdeck instead of main panel.

Powering the 5mW Artemis Nano fully on a 10.5 Phillips LED
03/09/2021 at 05:04 • 0 commentsGot my Artemis Nano to power on completely with a 10.5W LED, far less than the 45W Cowboy Studio CFL I was using with the 2V, 160mAh panel in my previous log . Since the bluetooth LED is is blinking, it must be using around 5mW, which is probably not very efficient, although it is the only way I can connect [using an Adafruit Universal USB / DC / Solar Lithium Ion/Polymer charger w/ TI BQ24074) the 5W panel to the USB-C input of the Artemis Nano at the moment. Some efficiency loss is likely, since it travels through the 500mA boost converter.
Later I put the lampshade back on the Philips and was able to get a red LEDd, but it took a while for current to flow through the entire circuit. With some efficiency improvements (i.e soldering the 500mV boost and panel placement), it is very likely that the Artemis Nano can be powered in a more ambient condition (i.e not a bulb directly on the panel as in the above photo.)
I’ll also try my Powerfilm Dev-in-Basic w/ BQ25570 development kit sometime.

Sparkfun Artemis Nano LED powered by ordinary lightbulb

Monocrystalline Silicon Solar Panel 2V 160mA 50*50mm& 800 Lumen Philips 10.5W bulb 2700K.
The next step is to get the blue light that flashes when it boots with a standard 3.7V battery & recharge the battery at the same rate it discharges. A larger solar panel will easily work, but I had to unplug it because the Nano immediately started smoking, not realizing I was using the wrong 4.4V out with an Adafruit Solar Lipo Charger. Really important tip: Make sure you have the right regulated output or it will fry the MCU
I attended a webinar by E-peas, Epishine & Cap-XX, and found this slide helpful

1st Indoor Test w/Led On
02/18/2021 at 19:46 • 0 comments2/18: 1st successful test of any indoor panel: Panasonic AM-1816CA with Waveshare Solar Power Manager (even though the latter is for 6V-24V) the AM1816CA is 4.9V.
Cowboy Studio 85W (450W equivalent) CFL was used.

The boot light (top right corner) also flickers on with enough light, but hasn't been able to charge a 3.7V battery yet.
