[Gaurav Taneja] was showing off his projection clock add-on for iPhone called Clockety at this year’s Consumer Electronics Show. The concept is pretty neat, a clip-on clock which uses the iPhone flash LED as the light source. It may sound a little gimmicky until you see the functionality of the accompanying app which is shown off in the video after the break. Once clipped onto the phone, you lay it face down on your night stand and a gentle tap on the furniture will turn the projection on or off. This is a killer feature when you’re staying some place without an illuminated bedside clock.
Professor [Bruce Land] teaches a microcontroller class at Cornell University, and it seems like this year’s theme was selfie-taking-robots.
First up is a clever mix of technology by [Han, Bihan and Chuan]. What happens when you take an iPhone, three microphones and a microcontroller? The ultimate device in selfie-taking-technology, that’s what — Clap-on! The iPhone is mounted on a few servo motors which allows the bot to direct the camera towards, you guessed it, a clapping noise. On the second clap, the phone takes your picture. Cute.
Next up is a bit more sophisticated — a facial recognition selfie-bot. This little robot can be programmed to track faces and take pictures of you and your friends when your arm is just not long enough. Not only that, you can set all kinds of parameters so you get the perfect picture. It uses OpenCV to crunch the raw data and outputs commands to an ATmega1284 which controls the servo motors that direct the camera. This project was by [Michael and Jennifer] — two fourth year students at Cornell.
With another wave of holiday parties about to land on our doorstep, we still haven’t found a great way to stop scalding our tongues each time [Uncle Dave] pours us an enticing cup of boiling cocoa.
Thankfully, [Ken] has both you and your holiday guests covered with a clever trick that takes the data from a FLIR ONE and projects a heat profile onto the surface it’s observing. Here, [Ken] has superimposed his FLIR ONE data onto his kitchen table, and he’s able to visualize 2D heat profiles in near-real-time.
If you haven’t started quantifying yourself recently (and what are you waiting for?), the FLIR ONE is yet another opportunity to help you become more aware of your surroundings than you are now. It’s a thermal camera attachment for your iPhone, allowing you to see into the infrared band and look at the world in terms of heat. We’ve covered the FLIR ONE before, and we’ve seen ways of making it both clearer and more hacker-friendly.
As we tip our hats to [Ken], we’d say he’s a generous fellow. This hack is a clever inversion of the normal use case where you might whip out your FLIR-ONE-enabled iPhone and warn your cousins not to try the hot chocolate for a few more minutes. With [Ken’s] solution, the data is right there on your condiments and in plain sight of everyone, not just for you with your sweet, Star-Trek-augmented iPhone.
[Jeff McGehee] or how he likes to be known, [The Nooganeer] just finished his first big tech project after finishing grad school. It’s a connected thermostat that makes use of his old iPhone 4, and a Raspberry Pi.
Ever since [The Nooganeer] bought his first home with his wife back in the spring of 2014, he’s had ever consuming dream of adding home automation to every appliance. As he puts it…
Home automation has always been a fascination of mine. How much time and irritation would I save if I didn’t have to worry about turning things on and off, or wonder in which state they were left? How much more efficient would my home be? Wouldn’t it be cool to always know the state of every power consumer in my home, and then be able to record and analyze that data as well?
His first challenge was making a smart thermostat — after all, heating and cooling your house typically takes the most energy. Having used a Raspberry Pi before he figured it would be the best brain for his system. After researching a bit about HVAC wiring, [The Nooganeer] settled on a Makeatronics Solid State Relay board to control the HVAC. This allows him to use the GPIO’s on the Raspberry Pi in order to control the furnace and AC unit.

If you’ve ever had to repair an iPhone for a friend, you’ll know they have a ridiculous number of screws. Most companies standardize screws in their products, but since Apple doesn’t expect you to fix a phone yourself… they may have let this one slide.
You see, each of these screws is different. The red ones are 1.7mm long, the yellow one, 1.3mm, and the orange one, 1.2mm.
Guess what happens if you install either red or yellow screws into the orange spot, since your eyesight isn’t good enough to notice a 0.1mm difference? The screw will cut into the PCB and break several 50 micron traces, as shown in the picture above, causing a blue screen error on the phone.
[Sam Schmidt] is the owner of a repair outfit called iRepairNational, and he and his team spent a day trying to figure out the problem – it’s not exactly easy to spot. They’ve managed to repair it by cutting thin strips of copper foil (the width of a human hair) and floating it into place using the surface tension of the flux they were using for soldering. On average it takes them around 2 hours to do the repair, though they’ve done a few in just under an hour.
Since discovering and sharing the problem, they’ve had customers around the world sending in phones for repair – often at the fault of someone else trying to repair something completely different in the phone, and then using the wrong screw as they put it all back together.
Phones, MP3 players, designer bags, artwork, money…. anything with value will bring out the counterfeiters looking to make a quick buck. Sometimes the product being counterfeited isn’t even necessarily expensive. For example, an Apple iPad Charger. [Ken Shirriff] got a hold of a counterfeit iPad Charger, took it apart, and did some testing.
So why would someone buy a counterfeit product? To save some money! The counterfeits are usually cheaper to reel the potential buyer in thinking they are getting a deal. In this case, the Apple product costs $19 and the knock-off is $3, that’s a huge difference.
Oooh, look, a public charging station. Should you trust it? You might get juice jacked. Oh wait, you’ve got a USB Wrapper designed by [Scasagrande] to deny access to your datas.
This project was inspired by the USB Condom, but the problem with those is that they completely cut out the data lines and limit the charge rate to USB 2.0 (500mA). The data lines are used to communicate information about the charger’s power sourcing capabilities to the device. Many manufacturers short D+ and D- together, but Apple applies specific voltages to those lines.
[Scasagrande]’s USB Wrapper gives you options. You can set it to Dedicated Charging Port, Sony, Open Circuit, or Apple. The super-cool part of this hack is for you Apple fanboys. The bottom slider lets you emulate any Apple charger and use any USB cube (including one you may have made) as long as you have that funny cable in your messenger bag. The hardware is open source and available at [Scasagrande]’s repo.
