Hackaday ☛ 2025 One Hertz Challenge: An Arduino-Based Heart Rate Sensor
How fast does your heart beat? It’s a tough question to answer, because our heart rate changes all the time depending on what we’re doing and how our body is behaving. However, [Ludwin] noted that resting heart rates often settle somewhere near 60 bpm on average. Thus, they entered a heart rate sensor to our 2025 One Hertz Challenge!

Dedoimedo ☛ How to extend Android battery time between charges
Over the years, I have owned (and/or own) a variety of Android smartphones. For the most part, they all exhibited reasonably long battery time in between charges, more so than what you normally hear reported in various articles. My Motorola One Zoom could do about a week, even with several hours of video calls, video playback, music, browsing and alike. More recently, a Samsung A54 in my possession can do four days.
This latest report triggered a bunch of emails, with people asking me what kind of magic I'm using to get such results. Well, I thought, ain't it obvious? After all, if you've followed my rather long Android privacy guide, you will have already taken a lot of steps toward improved battery life. But, for the sake of completeness, let me show you what I do, how I do it, and what you can do to extend the charge time.
