Breakfast is a meal fraught with paradoxes. It’s important to start the day with a hearty meal full of energy and nutrition, but it’s also difficult to cook when you’re still bleary-eyed and half asleep. As with many problems in life, automation is the answer. [James Bruton] has the rig that will boil your egg and get your day off to a good start.
The basic apparatus uses a thermostatically controlled hotplate to heat a pot of water. [James] then employs an encoder-controlled linear actuator from a previous project to raise and lower a mesh colander into the pot, carrying the egg. An Arduino is used to measure the water temperature, only beginning the cooking process once the temperature is over 90 degrees Celsius. At this point, a 6-minute timer starts, with the egg being removed from the water and dumped out by a servo-controlled twist mechanism.
Future work will include servo control of the hotplate’s knob and building a chute to catch the egg to further reduce the need for human intervention. While there’s some danger in having an automated hotplate on in the house, this could be synchronized with an RTC to ensure your boiled egg is ready on time, every day.
Breakfast machines are a grand tradition around these parts, and we’ve seen a few in our time. Video after the break.

You’ll have to dig out your French dictionary (or Google translate) for this one, but it is worth it. [Nicolas Giraud] has been experimenting with ways to use a webcam to detect the number of eggs chickens have laid in a chicken coop. This page documents these experiments using a number of different algorithms to automatically detect the number of eggs and notify the owner. The system is simple, built around a Pi running Debian Jesse Lite and a cheap USB webcam. An LED running off one of the GPIO pins illuminates the eggs, and the camera then captures the image for analysis.

Pokemon Go has done a great service to the world health. Or would’ve done, if we wouldn’t hack it all the time. The game suggests, you breed Pokemon eggs by walking them around, but [DannyMcMurray] has a better idea: Strapping your smartphone to the propeller of a fan and taking them for spin that way.

You’d think that hatching chicks from eggs would be easy – after all, birds do it. But it turns out to be a fussy business for humans, and what momma bird does naturally isn’t necessarily easy for us. If your goal is to raise your own brood of peeps, fear not – this DIY egg incubator makes the process much easier.
While [Chris Raynerd]’s incubator was built for quail eggs, pretty much any domestic fowl – chickens, turkeys, ducks, pheasants – will work. The key is temperature control – momma bird’s rump is a natural heat source, and her downy feathers keep the eggs insulated and toasty. That’s a little hard to replicate in a free-air incubator, so [Chris] started with a polystyrene box for insulation. A halogen lamp on a digital thermostat provides most of the heat and keeps the temperature within a degree or two of 37°C. As a backup, a 12 volt halogen bulb on a dimmer keeps the chamber at a minimum of 36°, just in case the main lamp burns out. A small fan and a pan for humidifying water complete the atmospheric controls, although personally we’d arrange the fan to blow across the water to aid evaporation. And a simple grid lets [Chris] turn the eggs regularly, which is another vital service mom provides to her brood.
Sure, it could be Arduino-fied and servo driven, but why bother? This is a simple yet thoughtful build that should see a clutch through to hatching. We’ve seen a few egg incubators before, but even if you’re not interested in raising fowl, the techniques here could easily apply to incubators for biohacking or yogurt making, too.

[Chiprobot] has created an amazing compliant gripper. Designing robot hands (or end effectors) can be a perilous task. It is easy to give robots big, good, strong hands. Strong grippers have to be controlled by sensors. However, sensors can’t always be relied upon to ensure those hands don’t crush anything they touch. Hardware fails, software has bugs. Sometimes the best solution is a clever mechanical design, one which ensures a gripper will conform to the object it is gripping. We’ve seen “jamming” grippers before. (so named for their use of a granular substance which jams around the object being gripped).
[Chiprobot’s] gripper is something entirely different. He designed his gripper in blender, and printed it out with his Ultimaker 3D printer. The material is flexible PLA. Three plastic “fingers” wrap around the object being gripped. The fingers are made up of two strips of printed plastic connected by wire linkages. The flexible plastic of the fingers create a leaf spring design. The fingers are attached to a linear actuator at the center point of the gripper. The linear actuator itself is another great hack. [Chiprobot] created it from a servo and an empty glue stick. As the linear actuator is pulled in, the fingers pull around any object in their grip. The end result is a grip strong enough to hold an egg while shaking it, but not strong enough to break the egg.
We would like to see the gripper gripping other objects, as eggs can be surprisingly strong. We’ve all seen the physics trick where squeezing an egg with bare hands doesn’t break it, yet squeezing an egg while wearing a ring causes it to crack much… like an egg.

Here’s a concept piece that monitors the eggs in your refrigerator. It’s still in development and we don’t think the general public is ready for digital egg monitoring quite yet. But we love the concept and want to hear from you to see if you could develop your own version.
What we know about the device is that — despite the image which makes smart phone proximity seem important — it connects to the Internet from inside your fridge. It will tell you how many eggs you have left, and even tracks the date at which each entered your refrigerator.
So, what’s inside this thing and who can build their own the fastest? We’ll cover some specs and speculate a bit to get you started: There’s a light sensor to detect when the door opens and an LED below each egg to illuminate the oldest. We think the light sensor triggers a microcontroller that uses each of the egg LEDs as a light sensor as well. If the threshold is too low then there is indeed an egg in that cup. We also like the fact that the tray has fourteen slots; as long as you don’t buy eggs until you have just two left you’ll always have room.
If you build one we want to know. We’re thinking 3D printed cups, low-power microcontroller, but we’re kind of stumped on the cheapest WiFi solution. Leave your thoughts in the comments.

This is a project to keep in mind for the kids next Easter. It uses electronics to light up your eggs instead of dying them (translated).
The project still has one foot in the old tradition as it starts by blowing out the eggs. The larger hole on the bottom, which was used to evacuate the yoke an albumen, ends up being just the right size to insert an LED. You could simply hook these up to a battery and resistor, but [Rene] decided to add some functionality by hiding an Arduino board in the fake grass of the Easter basket. This way the way the RGB LEDs can glow, blink, and rotate through different colors. And the foil covered chocolate bunnies aren’t just for show. He wired them up to the I/O pins of the Arduino to use as a switch. When they’re both placed on the same piece of foil it completes the circuit and starts the light show. See for yourself in the clip after the jump.
Of course for the older kids you’re going to need something more complicated to keep their attention.
