The Internet of Three-Pointers

When tossing something into the rubbish bin, do you ever concoct that momentary mental scenario where you’re on a basketball court charging the net — the game’s final seconds ticking down on the clock — making a desperate stretch and flicking some crumpled paper perfectly into the basket only for no one to notice your awesome skills? Well, now you can show off how good you are at throwing out garbage.

Well, not strictly garbage. The genesis of this IoT basketball hoop was in fact an inflatable ball on [Brandon Rice]’s desk that he felt would be more fun to …read more

Memcached Servers Abused For DDoS Attacks

Cloudflare announced recently that they are seeing an increase in amplification attacks using memcached servers, and that this exploit has the potential to be a big problem because memcached is capable of amplifying an attack significantly. This takes DDoS attacks to a new level, but the good news is that the problem is confined to a few thousand misconfigured servers, and the solution is to put the servers behind a tighter firewall and to disable UDP. What’s interesting is how the fundamental workings of the Internet are exploited to create and direct a massive amount of traffic.

We start with …read more

Internet of Things Opens Possibilities

While a lot of hardware gets put on the “Internet of Things” with only marginal or questionable benefits (or with hilariously poor security), every now and then a project makes use of this new platform in a way that illustrates the strengths of IoT. [ThingEngineer] turned to this platform as a cost-effective solution for an automatic gate, since new keyfobs were too expensive and a keypad was not an option.

Using an Electric IMP, [ThingEngineer] began by installing his IoT patch into the LiftMaster gate control box. This particular gate has easily accessible points that the controller can access to …read more

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
