Hackaday Podcast 030: Seven Years Of RTL-SDR, 3D Printing Optimized For The Eye, Sega Audiophile, Swimming In Brighteners

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.

Take a look at the links below if you want to follow along, and as always tell us what you think about this episode in the comments!

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.
