I originally used this for an arcade cabinet where powering everything off from a single switch on the back could have caused problems for the pi. It works a treat and neatly shuts it down after about 20 seconds. I've got a second one that will be ideal for a portable project as well. The documentation is pretty comprehensive but thanks to the support team who've answered my questions promptly.
I've been using an AdaFruit PowerBoost 1000 but it doesn't quite provide enough juice since I added an extra USB device. The fact that with the PiVoyager I can monitor it and do a clean shutdown if required is a bonus.
In our use case, we have a Rpi zero that we want to operate in demo mode for a period of time and then turn off. It can be turned on again by pressing a button or at a certain time of day. We also wanted the Rpi to turn itself off, and come on again at a certain time of day. All this was accomplished by simply adding the PiVoyager, a switch, a battery and a little bit of code. Since the PiVoyager also monitors battery voltage, we can have the Rpi notify the user when it needs to be recharged. The PiVoyager takes care of the charging once usb power is applied. Great idea and implementation.
I have zero understanding of DYI electronics, and needed the Game Clock to function as a display for a time machine art installation. Although the Game Clock is fully user-programable the developer wrote custom code to support the exact needs of my project. They went over and beyond expectation. The developer collaborated with me, suggesting improvements to my initial concept, resulting in a more thoughtful and usable execution of the functionality. Plus, the programming service was price affordably. The developer always responded quickly to my inquires with well articulated information. It was an absolute pleasure doing business with Omzlo. Overall satisfaction: 5/5
For those interesting in how the Game Clock programming was customized to my specifications, below describes the new functionality: —The Game Clock displays, per request, by default, "1970" on the left display, and "2019" on the right display. —Pressing the central tach switch briefly once allows the user to change the year displayed on the left display (using the left and right snap action micro-switches to go back or forward in time in one year increments). —Pressing the central tach switch briefly a second time allows the user to change the year on the right display. —Pressing the central tach switch a third time sets the edited year dates. —Long pressing the central tach switch (approx. 3 seconds) will give the user access to the display brightness setting (using the left and right snap action micro-switches to adjust the brightness down or up).
