Make: Volume 83

It's been another tumultuous year in the world of embedded electronics: Supply chain snags have scarcely relented, while new chips jostle for position as the go-to for makers. In this issue of Make:, we look at how scarcity is affecting the industry and impacting new and stalwart boards alike. We explore how RISC-V chip architecture is putting open silicon in the hands of makers. And if your favorite board is out of stock, we offer smart substitutes. Also included is our annual Make: Guide to Boards comparing 79 of the hottest microcontrollers, single-board computers, and FPGAs â?? with an emphasis on those you can actually get your hands on.

Plus, 25 projects to make, including:

• Use full-color LED strings and a Pixelblaze controller to make cuddly animated pillows.

• Convert your 3D printer to 5-axis and print the impossible.
• Take control of smart home gadgets with Z-Wave and Raspberry Pi.
