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 […]
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 […]
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 […]
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 […]
Yesterday I completed a long project to install two Raspberry Pi computers with solar power along our driveway, so we can see our gate. They are verra nice. I bought two fake security cameras to get the housings, each one contains a 12VDC to 5VDC buck converter, a Raspberry Pi 2 computer and a Raspberry […]
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.
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, […]
