If you have been doing OpenCV or Python machine learning, you have most likely come across PyImageSearch. If you come across a sale for this service I would recommend trying it out if you are learning some machine learning. This past week they have run a free promo 7 day trial, which gave me an opportunity to browse these.

There are many cheap ($5-20) USB RTL-SDR devices you can find on Newegg or Amazon that have an unexpected extra of being able to pick up broadcast radio. This is a handy feature, and in fact we can even read ham-radio frequencies by changing the bandwidth and frequency to read. There are excellent howtos on the easy installation of GQRX for just listening to the radio and setting your frequency and listening, and that’s a good way to start with testing your device. In this post I’ll show how to read and listen to radio using just Python and the Python RTLSDR library, which will show a lot more detail in how decoding radio works, and lets you run a clean interface to listen or record radio.

Today we did some up-cycling of political ad signs. After elections these generally go in the trash, but Talent Maker City had a public event to build some cool stuff out of these corrugated plastic boards! (Update- see the howto for version 2 of a durable cargo bicycle box here)
