I have assembled 6 more devices, for a total of 8. Collecting the parts, assembling them and programming the 6 took slightly less than 1 hour, that is 10 minutes for each device. Not bad.
Notice the 2 ways to connect the power, supported by the PCB: using terminal blocks or DC jack. Of course, any combination of the 2 is possible. I prefer terminal blocks for all the devices that are out of warranty and I can cut the cord to as this allows for a more optimal placement, such as at the middle of the cable.
And finally, some tests with the most relevant type of device: the router. Disclaimer: this is not the router it will be used for, fortunately this can run OpenWrt.
Camera installation coming soon… and possibly a 3d printed case, although i have some project cases that fit the device nicely and that is a faster way to get things done.
Project is now complete: will report in a few months with the performance of the device!
