ONiO.zero Offers Up to 24MHz of RISC-V Microcontroller Performance on Nothing But Harvested Energy

No batteries, no supercapacitors, no problem: ONiO claims its design can harvest power from the radio spectrum to operate at up to 24MHz.

Norwegian healthcare-focused Internet of Things (IoT) specialist ONiO has unveiled ONiO.zero, an ultra-low-power RISC-V-based microcontroller capable of operating wholly from harvested energy — without needing a battery, capacitor, or any other form of energy storage.

ROCK Pi SATA HAT Targets ROCK Pi 4 & Raspberry Pi 4 NAS

Raxda ROCK Pi 4 is a single board computer (SBC) powered by Rockchip RK3399 hexa-core processor and inspired by Raspberry Pi 3 Model B+.

The company has now designed ROCK Pi SATA HAT expansion board to design 4-bay NAS based on Raspberry Pi 4 and ROCK Pi 4.

There are 3 models with support for 2, 4 or 5 drives:

  • Dual/Quad SATA HAT connected over two USB 3.0 ports and working with both boards
  • Penta SATA HAT connected over PCIe and compatible with ROCK Pi 4 only

CPU Revealed! AtGames Legends Ultimate Arcade Mainboard Teardown

So ever since I got my hands on the new AtGames Legends Ultimate Arcade I have been wondering what CPU is powering this arcade cab but the Heatsink is soldered onto the mainboard so in order to remove it we have to drill or desolder it! and in this video, I finally get the heatsink off the board and find out what Cpu and how much ram this cabinet is rocking! Is it RockChip, Allwinner Amlogic? Let’s find out.

The Probe-Scope Is a 60MHz 250Msps Oscilloscope That Fits in Your Hand

A year ago, electrical engineer Mark Omo unveiled his 1 Square Inch 20Msps Oscilloscope designed around a PIC32MZ EF, which used its internal ADCs in an interleaved mode to gain that 20Msps. It even had an integrated 1″ x 1″ OLED screen for the readouts. Now he’s back once again with another oscilloscope project, the Probe-Scope, a self-contained 60MHz 250Msps oscilloscope and probe in cable form factor — meaning all the acquisition hardware is contained along the cable.

This Can Coat Anything in TITANIUM

Titanium is a pretty fantastic materiel on it’s own, but if you can coat things in it you can radically alter their properties. Or just make them super colorful. In several previous videos we’ve explored how to coat all sorts of things in a variety of metals and materials, but titanium was one of the few that refused to work no matter what we tried. In this video we’ve finally cracked it and using thermal evaporation manage to coat all sorts of things in titanium metal.
