Evolution of the ESP8266 Party Button

Sometimes the best part of building something is getting to rebuild it again a little farther down the line. Don’t tell anyone, but sometimes when we start a project we don’t even know where the end is going to be. It’s a starting point, not an end destination. Who wants to do something once when you could do it twice? Maybe even three times for good measure?

That’s what happened when [Ryan] decided to build a wireless “party button” for his kids. Tied into his Home Assistant automation system, a smack of the button plays music throughout the house and …read more

Most parents would do anything to enrich their kids’ worlds and teach them what they need to know.

All too often there’s nothing that can be done, but occasionally there’s a window of opportunity to make things better for the child, even if we can’t offer a cure.

Root on the Philips Hue IoT Bridge

Building on the work of others (as is always the case!) [pepe2k] managed to get root access on the Philips Hue Bridge v2 IoT light controller. There’s nothing unusual here, really. Connect to the device over serial, interrupt the boot process, boot up open firmware, dump the existing firmware, and work the hacker magic from there.

Of course, the details are the real story. Philips had set U-Boot to boot the firmware from flash in zero seconds, not allowing [pepe2k] much time to interrupt it. So he desoldered the flash, giving him all the time in the world, and allowing …read more
