Daniel Estévez ☛ Decoding Europa Clipper
I used one of the ATA antennas to record the X-band telemetry signal for about 2 hours and 50 minutes, until the spacecraft set again due to Earth rotation. In this post I overview the recording and decode the telemetry with GNU Radio.
I recorded at 6.144 Msps IQ, but since the telemetry symbol rate was only 12 kbaud throughout all the recording, I have made files decimated to 96 ksps and published them in the dataset “Recording of Europa Clipper X-band telemetry with the Allen Telescope Array shortly after launch” in Zenodo. This decimation discards the sequential ranging tones, which were present during most of the observation, but it greatly reduces the file size.

Arduino ☛ Technology meets creativity in two interactive art student projects
Flora, created by College of Arts & Design of Barcelona students Judit Castells, Paula Jaime, Daniela Guevara, and Mariana Pachón, is a board game in the form of an interactive art installation. It was inspired by nature, with gameplay occurring throughout a simulated ecosystem. An Arduino UNO R4 WiFi board handles the interactive elements, with additional hardware including NFC readers, motors and accompanying drivers, sensors, pumps, LEDs, and more.

PC World ☛ How to turn any SSD into a DIY external drive
SSDs are now the norm in computers. With older laptops and desktop PCs, the low capacity of the original SSD is usually the main reason for an upgrade, with the old SSD replaced by one with more space.
However, the old SSD need not be retired completely — it can still be put to good use as external storage.
