Hackaday editors Elliot Williams and Mike Szczys flip through the index of great hacks. This week we learn of a co-existence attack on WiFi and Bluetooth radios called Spectra. The craftsmanship in a pneumatic drone is so awesome we don’t care that it doesn’t fly. Building a powerful TEA laser is partly a lesson in capacitor design. And join us in geeking out at the prospect of big rigs getting their juice from miles of overhead wires.

- Elliot’s Picks:
- Mike’s Picks:
The trains and trucks conversation was a bit overwhelmed by the logistics side of it, so what was skipped over was the cost calculation that didn’t account for capacity factors, so it under-estimated the cost of the wind turbines by a factor of 3-5x
