Do you want to build a uninterruptible power supply (UPS) system which will keep your Raspberry Pi 4B online 24/7/365 without hassle? This isn’t one of those gimmicky tutorials which uses a tiny cell phone charger with an 18650 battery built in that is technically capable of powering a potato… No, I’m using some heavy duty materials

I. Introduction FOR the 2017 solar eclipse ballooning, the live streaming of the videos capturing the shadows of the solar eclipse was one of the main objectives. All teams who participated in the 2017 solar eclipse ballooning project were initially provided with a baseline ballooning system [1][2] that consisted of a ground station and four
Combines basic woodworking (house/feeder) with a Pi Zero W/cam powered by batteries/solar & turned on/off w/ an ATtiny85 and BH1750. Story Background I live half a mile above sea level and am SURROUNDED by animals… bears, fox, turkeys, deer, squirrels, birds. Spring has arrived and there are LOADS of squirrels running around. I was in

Sunlight may be free, but transforming it into usable electricity is not. I learned this back in 1965 when I bought some surplus silicon solar cells from dealer Herbach and Rademan (now H&R Company, Inc.). Those 0.75″×0.75″ cells cost around $2.49 each or $19.30 today according to the CPI Inflation Calculator. In 1975, I used
