试着接收了这次《三体》联动哈工大从阿斯图一号卫星上发送的 SSDV信号,只能说发送的图片真的好难看(),不过搭建解码环境的过程还是比较有趣的,也学会了 sdr 精准跟随卫星频率的操作。 #业余无线电#HAM#卫星#SSDV#ASRTU-1

It works with popular smart home systems like Home Assistant and can send data wirelessly using Bluetooth or Zigbee. The device is easy to build or buy, comes with free designs and software, and can be protected with a 3D-printed case. This helps you keep your plants healthy by giving you clear, regular updates on their environment, so you know exactly when to water or adjust conditions[1][2][3]. https://github.com/rbaron/b-parasite
