SLZB-Ultima: A Quad-Radio Smart Home Radio Controller Supporting Various Protocols

While not based on SDR technology, we think that some readers may be interested in this product.

We'd like to thank Serhii, who writes on behalf of SMLIGHT in Ukraine. SMLIGHT recently released its "SLZB-Ultima" device, a compact radio platform supporting multiple wireless technologies commonly used in smart homes. 

These technologies include Zigbee, Thread, Wi-Fi, and Bluetooth. The device also optionally supports Z-Wave, LTE, Power-over-Ethernet, UPS backup, infrared control, and USB-over-Ethernet. The cloud-independent software supports WireGuard VPN, Dynamic DNS, Internal Zigbee hub mode, local IF-THEN automations running directly on the device, and one-click OTA updates.

The full press release is available here in this PDF.

The device is priced affordably at only US$40 on Aliexpress.

Spectrum Slit: A Wall Art Display That Visualizes Wi-Fi Activity via a HackRF

Over on YouTube, RootKid, who specializes in creating engineering-based art projects, has developed an interesting wall-mounted art display panel that visualizes Wi-Fi activity by using a HackRF as the monitoring software-defined radio. The display uses a Raspberry Pi, a HackRF, and a custom-made LED light bar. The HackRF receives a 5 GHz Wi-Fi channel, and the Pi translates this into activity on the LED display, creating a visual piece that lets those around know when Wi-Fi activity is high.

The idea is to show that "we live surrounded by ghosts of our own making", which refers to the invisible storm of electromagnetic signals that we created to serve us in our modern lives.
