Journey towards Making the Most Efficient Garden / Pathway Light
When I first started with Solar Lighting it was to create a simple robust street light.
Created a Light that was good and robust. It was a typical Solar Street Light.
The LEDs were superflux capable of being driven to 50mA - The cooling was provided by the four leads and the PCB was made with lots of copper area to dissipate the little heat.
The design as based around a PIC micro-controller and the output was switching via the controller.
This was in 2005.
Since then I have tried various designs in lighting streets, gardens, porches and pathways.
I am on track to now make one of the most efficient lighting for Gardens, Walkways, pathways and porch lighting.

USB Meter - For Measuring Capacity of a USB Power Bank & Other 5V Devices
You have bought a power bank and are wondering if it really measures up to the advertised Capacity?
Check with this Power Meter.
You can connect it to any USB Power Source like your Power Bank.It will Show you the Output Voltage of the Power Bank - This should be 5VOn the USB Female side you connect your Load.You can then see the Current that the Device Consumes.Leave it on for a while and it can give you an indication of the Power Consumed. This is also the Power delivered by the source (Could be your Power Bank)
It measures Voltage & Current - Power = Voltage x Current (For DC Voltages like this one)
The Total Energy that can be delivered by your Power Bank = The Capacity of your Power Bank.
Energy (Or Capacity) is the ability for the Power Bank to give X Watts for T Time before it runs out of juice.
Hence TIME is the factor that comes into play to measure the Total Energy that can be delivered by your Power Bank or The Capacity of your Power Bank
Capacity = Total Energy that y…
