In this post update, We will compare different micro-controller candidates based on multiple criteria and examine each candidate as a possible processor option of each micro node. The main two criteria of selecting the node micro-controller are the cost...
We have been using EM Microelectronic's EM7180 motion co-processor for absolute orientation estimation with some success. The EM7180 embeds a 10 MHz ARC processor with single-precision floating point unit (FPU) optimized for fast fusion calculations...
Hello everyone! Today I want to share with you my new DIY project. It is an open source air quality sensor. This project uses a novelty from Sensorion - TVOC sensor SGP40. The second main element of the project is the 2.13-inch e-ink display. I think...
TL;DR: WHAT I THINK IS COOL ABOUT MY PROJECTF1 inspired design: Twin 7-segment LCDs on top with a rotary knob in the center, flanked by buttons on either side. Look up "2010 F1 steering wheel" to see what I mean.Accurate timekeeping: Timekeeping...
