So cool to see another person going to UT on HN! I'd love to organize a Jet Lag style game in Austin sometime.

Hi! Wanted to share this cool project me and some friends worked on during the summer of '23, now that the video is finally edited. It was an incredible experience, hope you like it :)

No comment on the thread, but I smiled at seeing myself quoted on HN :)

> The alternative would be that anyone could send notifications to an app No, the alternative is that anyone with a password the app generates can send notifications to any app, which is (effectively) how WebPush and UnifiedPush work.

Since this is a tutorial for newbies, I'm intentionally using a chip with years of code, flashing, and peripheral circuit examples. It's also compatible with the Arduino Nano pinout so students can add peripherals with outside cir

Nice project idea. The Nordic chip in the Pinetime might be more efficient than this ESP-32 though, and there's been a lot of development effort into infinitive for it.

Doesn't all tap water contain the forever chemical H2O? /s I hate how they're scaremongering with the vague term "Forever Chemicals" instead of just using the more specific terms PFAS or Microplastics.

Yes absolutely! I love the RP2040 and have used dev boards for several projects. My goal with this intro is to make something hand-solderable though, which is why I'm using QFP32, 0805, etc. In addition, this is Arduino Nano compatible

I'm writing a series of articles on designing a microcontroller board (with an ATmega328P) from scratch [1]. It's a totally different experience from just breadboarding. Some people are making NFC business cards, USB Hubs, and eve

Having WebPush style push notifications is a huge advantage of JMAP. Right now, 3rd party mobile email clients are stuck to polling every few minutes or keeping a connection open. I'm looking forward to more JMAP adoption, especially o

No, I was simply replying to: > none of the GPIO pins are exposed, the only IO is buttons, usbc or a QT/Stemma connector. Sorry for losing context.

Because the RP2040 is so dynamic, the QT/Stemma connector is two GPIO pins, even thought it can do I2C or SPI.

> small CR2032 coin cells (which have ~10 to ~100 ohms of internal resistance). A ~100mA draw on the charge inductor isn't out of the question (at 10-ohms, that's a voltage drop of 1V, which probably browns-out the RP2040). n=1

It is kinda weird. However, at the end of the day, UnifiedPush is just a protocol that allows $heavyProtocolA to receive notifications through $lightProtocolB. And XMPP is just $lightProtocolB, there is nothing stopping an XMPP-based Unifie

For cross platform UnifiedPush libraries, such as Flutter, it totally makes sense to support iOS by wrapping APNS. Unfortunately, most people on the UP team don't have Apple devices, or iOS development experience. Maybe someday...
