Hackaday Prize Entry: An Internet Doorbell

The Internet of Things will kill us all and is the worst idea anyone has ever had. However, just because something could be labeled an ‘Internet of Things thing’ doesn’t mean it’s a bad idea. The Hackaday Prize’s Internet of Useful Things challenge was all about finding the Internet of Useful things, and one of these projects is so simple yet so elegant, we’re surprised no one has thought of it yet.

[David]’s entry to the Hackaday Prize is effectively an Internet of Things doorbell. You might think an IoT doorbell would just consist of a device sending push notifications …read more

Hackaday Prize Entry: Internet of Fidget Spinners

We just closed out the Internet of Useful Things round of the Hackaday Prize, which means we’re neck deep in judging projects to move onto the final round this fall. Last week, everyone on Hackaday.io was busy getting their four project logs and illustrations ready for the last call in this round of the Hackaday Prize. These projects are the best of what the Internet of Things has to offer because this is the Internet of Useful things.

We’re not sure how [Matthias]’ project will rank. It’s an Internet of Things fidget spinner. Yeah, we know, but there are some …read more

A Magic Light Bulb For All Your Bright Ideas

[Uri Shaked]’s lamentation over the breaking of his smart bulb was brief as it was inspiring — now he had a perfectly valid excuse to hack it into a magic light bulb.

The first step was disassembling the bulb and converting it to run on a tiny, 130mAh battery. Inside the bulb’s base, the power supply board, Bluetooth and radio circuits, as well as the LED board didn’t leave much room, but he was able to fit in 3.3V and 12V step-up voltage regulators for the LiPo battery.

[Shaked]’s self-imposed bonus round was to also wedge a charging circuit — …read more

Hackaday Prize Entry: USB GSM GPS 9DOF SD TinyTracker Has All the Acronyms

[Paul] has put together an insanely small yet powerful tracker for monitoring all the things. The USB TinyTracker is a device that packages a 48MHz processor, 2G modem, GPS receiver, 9DOF motion sensor, barometer, microphone, and micro-SD slot for data storage. He managed to get it all to fit into a USB thumb drive enclosure, meaning that you can program it however you want in the Arduino IDE, then plug it into any USB port and let it run. This enables things like remote monitoring, asset tracking, and all kinds of spy-like activity.

One of the most unusual aspects of …read more

Hijacking the Sonoff OTA Mechanism

ITEAD’s Sonoff line is a range of Internet-of-Things devices based around the ESP8266. This makes them popular for hacking due to their accessibility. Past projects have figured out how to reflash the Sonoff devices, but for [mirko], that wasn’t enough – it was time to reverse engineer the Sonoff Over-The-Air update protocol.

[mirko]’s motivation is simple enough – a desire for IoT devices that don’t need to phone home to the corporate mothership, combined with wanting to avoid the labor of cracking open every Sonoff device to reflash it with wires like a Neanderthal. The first step involved connecting the …read more

Putting Pi In Infrared Doohickies

The Raspberry Pi Zero W is a tiny, cheap Linux computer with WiFi. It’s perfect for Internet of Things things such as controlling ceiling fans, window blinds, LED strips, and judgmental toasters. This leads to an obvious question: how do you attach your ceiling fan and LED strips to a Pi Zero? A lot of these things already have infrared remotes, so why not build an infrared hat for the Pi? That’s what [Leon] did, and it’s Open Hardware with documentation.

[Leon]’s Anavi Infrared Pi Hat does exactly what you think it should do. There’s an IR receiver, two IR …read more

Your Internet of Things Speaks Volumes About You

If only Marv and Harry were burglars today; they might have found it much easier to case houses and — perhaps — would know which houses were occupied by technically inclined kids by capitalizing on the potential  vulnerability that [Luc Volders] has noticed on ThingSpeak.

As an IoT service, ThingSpeak takes data from an ESP-8266, graphs it, and publicly displays the data. Some of you may already see where this is going. While [Volders] was using the service for testing, he realized anyone could check the temperature of his man-cave — thereby inferring when the house was vacant since the …read more

Printer Vulnerabilites Almost as Bad as IoT

Recently ZDNet and Gizmodo published articles outlining a critical flaw in a large array of personal printers. While the number of printers with this flaw is staggering, the ramifications are even more impressive. Ultimately, any of these printers could have documents sent to them stolen even if the document was only intended to be printed as a hard copy.

Luckily the people responsible for this discovery are white-hat in nature, and the release of this information has been made public so the responsible parties can fix the security flaws. Whether or not the “responsible party” is the manufacturer of the …read more

Dash With Arduino

Amazon Dash is a handy service, and when Amazon released their AWS IoT platform, [Brian Carbonette] felt that it left out all the hardware hackers from the tinkering fun. Seeking justice, he put together a guide for an Arduino Dash button aimed at hardware hackers and those who are still easing into the world.

For his build, [Carbonette] used an Arduino MKR1000, laying out a few different configuration options for building your button. He has also gone to great lengths to help all comers tackle the Arduino-Dash API communication process by building an AmazonDRS Arduino Library, which handles …read more

Open Your Garage Door With Your Smartphone

The eternal enemy of [James Puderer]’s pockets is anything that isn’t his smartphone. When the apartment building he resides in added a garage door, the forces of evil gained another ally in the form of a garage door opener. So, he dealt with the insult by rigging up a Raspberry Pi to act as a relay between the opener and his phone.

The crux of the setup is Firebase Cloud Messaging (FCM) — a Google service that allows messages to be sent to devices that generally have dynamic IP addresses, as well as the capacity to send messages upstream, …read more
