Hackaday Editors Mike Szczys and Elliot Williams curate the awesome hacks from the past week. On this episode, we marvel about the legacy RTL-SDR has had on the software-defined radio scene, turn a critical ear to 16-bit console audio hardware, watch generative algorithms make 3D prints beautiful, and discover why printer paper is so very, very bright white.

Computer Optimized 3D Printed Bookshelves

[Thomas] does a lot of interesting experiments with 3D printing and lately, he’s been using the free version of Fusion 360 to do topology optimization. He started with a blocky bookshelf bracket and let the software analyze the loads so it can remove pieces that don’t contribute a lot to the bracket’s strength. This uses less material, prints faster, and — [Thomas’] biggest goal — looks cool.

If you know [Thomas] you know he didn’t just hope the brackets would be strong enough. He made prototypes and destroyed them in testing. Despite being printed in a poor orientation for strength, the models held a good bit of weight.
