  • We don’t need a DAC – ESP32 PDM Audio

    So, there’s no DAC on the ESP32-S3. You would think this would be a bit of a downer if if you want to get audio out and use an analog amplifier. But it’s actually surprisingly easy to output Pulse Density Modulated audio using Sigma Delta Modulation on the ESP32 and you can recover the audio signal by low…

  • ESP32-based Internet Radio Streamer

    So I entered my favorite internet radio’s URL, plus my WiFi credentials into the code and loaded it to my ESP32 using the Arduino IDE. Surely enough, I saw in my serial port that the ESP32 connected to my WiFi access point and then opened successfully the streaming radio station. I could see on my…

  • PW 4: Productivity and tools

    My experience of using ChatGPT to assist in code mirrors this… i was a little slower for a week or so and then I accelerated away. The tools that are available to each of us are so powerful, so varied and so complex that even the free ones are ignored or misunderstood. We’re too busy…

  • Musk once laughed off BYD as a threat. Now the Chinese giant has taken Tesla’s EV crown — here’s how

    Yesterday I posted about how sanctions against China are very very dumb. Here is another good example of why. Elon Musk dismissed BYD in 2011 by laughing at their products during a Bloomberg interview. “Have you seen their car?” Musk quipped. “I don’t think it’s particularly attractive, the technology is not very strong. And BYD as a company…

  • I built a SUPER HEATED STEAM THRUSTER (New Type of Rocket)

  • CH32 RISC-V MCUS GET OFFICIAL ARDUINO SUPPORT

    Just like the ESP8266’s popularity exploded when it was added to the Arduino IDE, we’ve got high hopes for the CH32 family in the coming months.

  • The Anti-China Chip Jeremiad Is The Stupidest Policy Imaginable

    The leadership of ASML had resisted these sanctions because they said it wouldn’t work: what would happen is that China would learn how to make the machines themselves. What he didn’t say, but it is true, is that ASML would not just lose the Chinese market, they would eventually lose the world market anywhere that…

  • PW 3: Errors and productivity

    If you’re not happy with the spec, change it. But once there’s a spec, goodenough is good enough.

  • New York’s Right to Repair legislation goes live

    There is a great Lupe Fiasco track called Dumb it Down. The first hook has the lyric: You’ll sell more records if you (Dumb it down!) That’s what the economy has been doing to us for the last 30 years (where ever software goes, it drags this virus with it). Making things unrepairable dumbs all…

  • A few reasonable rules for the responsible use of new technology

    Four really reasonable rules. Treat them as design constraints and I think we’re in a really good place. If there’s one thing which probably unites all of Hackaday’s community, it’s a love of technology. We live to hear about the very latest developments before anyone else, and the chances are for a lot of them…
