Lithium Powered 5V Solar Power Storage and Supply

I’ve built a new gadget to store electrical energy in lithium batteries for an outdoor application. It’s very simple, and it all fits in a weather tight enclosure. Here are the circuit drawing and a photo. As you can see the output is 5.1VDC, just right for a webcam or other SoC board gadget. Of […]

Building Gatecam 4

Gatecam number 4 is based on an Orange Pi with USB camera board. It replaces an earlier camera made with a Raspberry Pi. The Orange Pi using UVC video and MJPEG Server produces up to 15 fps at FHD (1920 by 1080) compared to a max of 4 fps with the Raspberry pi. I used […]

New Style Raspberry Pi Webcam

I’ve switched to using metal enclosures for my Raspberry Pi webcams, here are some photos of work in progress. There is more room and I expect long term durability. I’ve also experimented with raspistill switches too. Here is my current command line for a webcam aimed at a freeway intersection a mile away. I’m using […]

Original Solar Gadget Reused For Webcam Power

My first home made solar gadget involved a pair of motion sensing LED floodlights powered by a 50 watt solar panel with charge controller and 12V SLA battery. Over time I decided to add a few always-on USB-powered LED lights, so the patio is always dimly lit at night. This made the floodlights superfluous so […]

Solar Gadget Charger Update

Here is an update on my home made solar gadget charger. A new voltmeter is on its way, expected to have greater brightness in mid-day sun. Meanwhile the professional solar installation on our roof is producing over 100kWh daily at this long day time of year. It’s all good.

Home Made Solar Motion Floodlights and Gadget Charger

Using found materials whenever possible, I have cobbled together various bits to make a solar powered gadget charging station with two motion detecting floodlights. It’s a very unimportant project, but it keeps me from playing in the middle of the street. The metal box was originally a sonar fish finder left behind on our property, […]
