国際宇宙ステーション #ISS からの電波、三重県津市から液体アンテナでも取れました！
CMの都合で高度の低い18:30頃までの受信でしたが51でしっかり復調しました👍
コップの水位は14センチ位で2m のλ/4には満たないですが波長短縮効果である程度のマッチングにはなっていたと思われます♪

40mバンドと20バンドの回路図(違いはEクラスアンプとLPFの定数だけ)と対応するスケッチをGitHubにアップしました。

Sam Altman literally gave a 43-minute masterclass on turning ideas into billion-dollar companies:

I built an AI agent that lets me speak to car engines.

Dashboard lights waste time and money, so I built a tool that uses AI to diagnose issues.

I’ve tested it on 40 cars and it’s hitting 95% accuracy. making workflows faster, smarter, and more efficient.

The first time I was visited by the FBI... a homelab adventure!

We have developed a new tactile sensor, called e-Flesh, with a simple working principle: measure deformations in 3D printable microstructures.

Now all you need to make tactile sensors is a 3D printer, magnets, and magnetometers! 🧵

Steve Branam built a career at iRobot and Amazon Robotics by constantly learning. I asked how he keeps up with new tools and trends while working full-time. His answers are practical and motivating: https://t.co/AiQql13b75

This video on how to self-host your own media library with a Raspberry Pi was deemed too 'dangerous or harmful' for YouTube.

So here it is on X, instead:

When your robot logic has a little too much latency, PID controllers can be a lifesaver. My #ROS bot now tracks blue objects with noticeably more grace 🤖
I’ll put the link to the tuning video in the replies.

#ROS node active! It uses #OpenCV to look for blue blobs and then publishes the coordinates of the bounding box (of the largest detected blue object). A subscriber publishes (a very delayed) raw image feed to a flask server for debugging. Next up: driving!
