RAKwireless launches modules designed for LoRa and BLE5 connectivity
This month, RAKwireless launched a LoRa/BLE5 module based on the Ambiq Apollo3 Blue SoC and the Semtech SX1262 optimized for IoT applications. These new RAK11720 modules start at $7.99 and are compatible with Arduino programming.

How to build your own Raspberry Pi webcam
We slightly amended Max’s original design for the 3D-printed parts so they fit our newest Raspberry Pi Camera Module 3. You need to print just two small support pieces so that the Raspberry Pi Zero 2 W and the camera module will sit nicely inside an Apple iSight shell. You can find the parts on Printables, and download them for free. We found an Apple iSight on good old eBay and we’ve made a disassembly video to show you how to remove the internals.

EPROM Does VGA
If you wanted to create a VGA card, you might think about using an FPGA. But there are simpler ways to generate patterns, including an old-fashioned EPROM, as [DrMattRegan] points out in a recent video.

IOT Message Board Puts Fourteen-Segment Displays To Work
We’re not sure, but the number of recognizable alphanumeric characters that a seven-segment display can manage seems to have more to do with human pattern recognition than engineering. It takes some imagination, and perhaps a little squinting, to discern some characters, though. Arguably better is the fourteen-segment display, which has been pressed into service in this just-for-funsies IOT message board.

Convert your 3D printer into a metal cutting machine with an Electrical Discharge Machining kit (Crowdfunding)
Rack Robotics' Powercore is an Electrical Discharge Machining (EDM) kit that converts your existing 3D printer (or CNC router) into a machine capable of cutting high-precision and detailed metal parts. We've already seen 2-in-1 3D printers and laser engravers such as the Creality Ender 3 S1 Pro, but while this type of machine can usually cut plywood or engrave stainless steel, the laser is not powerful enough to cut through aluminum.
