For all those entertainment lovers who would like to watch their videos on a large screen, portable projectors such as the DeepLee DP300 mini projector and APEMAN mini portable projector were created. However, most of these existing projectors have some common issues such as the use of long cables or an inability to connect to Wi-Fi, but all those belong

This is the first post of a 3-part series about reading out an SMA solar inverter over Bluetooth and displaying some readings every few seconds. Long-time readers may remember the Solar at last weblog post from several years ago and the SMA Relay, based on a JeeNode v6. The Bluetooth readout code was derived from Stuart Pittaway’s Nanode SMA

Introduction The problem was this…at Redeeming Grace Church we were meeting in a public school prior to moving in to our permanent facility. Each Sunday morning we would bring in three large percolating coffee pots to brew regular, decaf, and hot water for the mid-service break time. Each pot drew 9 amps. Because the average

For applications demanding low power and longer battery life, the PIC32MM has sleep modes down to 500 nA. Applications with space constraints will benefit from the small 4x4mm package options. The PIC32MM devices include core independent peripherals, designed to offload the CPU for lower power and flexible system design, such as Configurable Logic Cells (CLC)
