Honestly this video was created before solar phone chargers existed. You can just buy a much better charger here: amzn.to/2pbcB63
In this video I show you how to build a 5V USB solar powered charger. Let me know if you have any questions!
Item list
5V regulator LM7805: $0.50
9 Volt, 3.3 Watt solar panel: $15.00
AAA battery enclosure: $1.00
Wire: salvaged
Total: $16:00

![TMP36 Temperature Sensor for Raspberry Pi and Arduino
I no longer sell these on Ebay, but you can buy them here: https://amzn.to/2H3dcP2
The TMP 36GT9Z is a low cost yet precise temperature sensor commonly used with a Raspberry Pi or an Arduino to measure air temperatures in °C via an output voltage (The graph/equation is below)
The equation to measure the temperature in °C is the following:
Temp in °C = [(Vout in mV) - 500]/10
