CNX Software ☛ SONOFF ZBMINIR2 tiny Zigbee 3.0 switch also works as a Zigbee router with up to 64 sub-devices
SONOFF ZBMINIR2 is a tiny Zigbee smart switch that looks very similar to the SONOFF Zigbee Extreme (ZBMINIL2) but requires a neutral wire and can act as a Zigbee router with up to 64 sub-devices. It also supports new features such as “Turbo mode” for extended range and “detach relay” mode where the states of external switches and relay are separated, so operating the external switch button won’t affect the relay state. The tiny wireless switch can fit into the smallest EU-type/86-type/120-type mounting boxes and works with gateways supporting the Zigbee 3.0 protocol such as ZBBridge Pro, NSPanel Pro, and other compatible Zigbee 3.0 hubs.

Hackaday ☛ Hackfest, A New Event For Your European Calendar
Our community’s events are something special, bringing as they do an opportunity to meet and mingle with other hackers whether their field be hardware, software, or security, to share ideas, and to see some very cool projects. Here at Hackaday aside from our own Supercon and Hackaday Europe events we try to take in as many as we can over the year, and thus it’s always interesting to sot a new one. If you’re in north-west Europe next weekend, consider dropping by Hackfest, in the Dutch city of Enschede, right on the German border.

Hackaday ☛ 3D Printing A Wire-Wrap Tool: Emergency Fix Or Permanent Solution?
Although less popular these days, wire-wrap is still a very relevant, easily reversible solder-free way to assemble (prototype) systems using wire-wrap wire and a wire-wrap tool. This latter tool can be either a hand or powered tool, but all it has to do is retain the stripped wire, fit around the wire-wrapping post and create a snug, oxidation-proof metal-metal contact fit. For the very common 30 AWG (0.25 mm) wire-wrap wire, the Jonard Tools (OK Industries) WSU-30M wire-strip-unwrap tool is pretty much the popular standard. It allows you to strip off insulation, wrap and unwrap connections all with one tool, but the question is whether you can just 3D print a wrap-unwrap tool that’s about as good?

CNX Software ☛ Waveshare 4-inch E-ink Spectra 6 full-color e-paper display is designed for the Raspberry Pi
Waveshare recently launched the 4-inch e-Paper HAT+(E), a E-Ink Spectra 6 full-color e-paper module designed to work with the Raspberry Pi using the HAT+ standard. This 600×400 pixel display includes E-Ink Spectra 6 technology and doesn’t have a backlight. The Spectra 6 allows for high contrast and color saturation whereas no backlight means the display consumes very low power. The device communicates using SPI and is compatible with various controller boards like Raspberry Pi and Arduino.

Hackaday ☛ Robotic Touch Using A DIY Squishy Magnetic Pad
There are a number of ways to give a robotic actuator a sense of touch, but the AnySkin project aims to make it an overall more reliable and practical process. The idea is twofold: create modular grippy “skins” that can be slipped onto actuators, and separate the sensing electronics from the skins themselves. The whole system ends up being quite small, as shown here.
