Cats can be wonderful companions, but they can also be aloof and boring to hang out with. If you want to get a little more out of the relationship, consider obsessively tracking your cat’s basic statistics with this display from [Matthew Sylvester]. The build is based around the Seeedstudio ReTerminal E1001/E1002 devices—basically an e-paper display […]
Sometimes it makes sense to go with plain old batteries and off-the-shelf PVC pipe. That’s the thinking behind [Bertrand Selva]’s clever LoRaTube project. PVC pipe houses a self-contained LoRa repeater, complete with a big stack of D-size alkaline cells.
