uMesh I’ve been working on an ESP32 module. Part of the problem I’ve been seeing with inexpensive IoT dev boards, is that the design around the power system hasn’t been very good. Here’s my attempt to fix that. This is a battery-ready module with a proper lithium battery charge circuit, lithium battery protection circuit, power […]

Adding wireless charging to furniture and other consumer goods is a nice way to add some oomph to an otherwise boring product. NXP’s NXQ1TXH5 provides an interesting, albeit difficult-to-prototype way around the problem. Creating a Qi-compatible is as easy as assembling the example circuit shown in figure one. From a technical point of view, the

It provides a very compact solution to evaluate the performance of the STSPIN820 stepper motor driver with a minimum set of additional equipment and without the need of additional devices. The hardware is fully compatible to be used together with RAMPS or other similar FFF 3D printing platforms, representing a very fast drop-in replacement of

Process computer designs usually start out with an accelerometer. As reliability problems creep in, making the switch to a more “professional” solution is beneficial. Accelerometers are based on the MEMS principle: instead of being a purely solid-state affair, the inside of the chip contains a micromechanical motion sensor along with a small mass. In addition

DESCRIPTION A small PCB designed to attach to the backside of the FLIR Boson Thermal Camera. The PCB facilitates configuration of the camera along with capturing data to an SD card. This project is mostly an exercise in project-based learning. Instead of researching and reading about FPGAs, I want to create a project actually using

Light moving in vacuum is the fastest thing in the universe. Scientists have tried many times before to catch it on the move with some success. This time a new equipment built by Caltech scientists pulls down a mind-blowing 10 trillion frames per second, meaning it can capture light as it travels along, and also they are working

Measuring just 0.9×0.6×0.3mm (50 % smaller than a conventional 32.768 kHz crystal resonator), the WMRAG series 32.768 kHz MEMS resonator is the world’s smallest, claims manufacturer Murata. Murata Manufacturing Co., Ltd. (Head Office: Nagaokakyo-shi, Kyoto; Chairman of the Board and President: Tsuneo Murata) has developed the world’s smallest 32.768kHz MEMS resonator, which is expected to
