If you want to keep eggs warm to hatch, you’ll need an incubator. You could buy one off the shelf, but they’re not so complex — just a nicely-controlled warm box you could easily whip up yourself. As it turns out, that’s precisely what [RCLifeOn] did.
The incubator is built out of wooden panels screwed together to make a simple box. The frame of the front door is also wood, but it features 3D printed hinges and handles, because that’s the easiest way to make hardware when you’re a printing wizard like [RCLifeOn].
The box is fitted with controls for humidity and temperature to ensure the best possible conditions for hatching chicken eggs inside. As you might have guessed, a heated bed from a 3D printer was used to control the temperature inside. As for humidity, a sensor tracks the conditions in the box, and triggers an ultrasonic mister to increase the level as necessary. There’s also a little motion introduced via a moving platform run by a motor and some step-down gearing, which apparently aids in the hatching process.
A common ratchet from your garage may work wonders for tightening hard to reach bolts on whatever everyday projects around the house. However, those over at [Chronova Engineering] had a particularly unusual project where a special ratchet mechanism needed to be developed. And developed it was, an absolutely beautiful machining job is done to create a ratcheting actuator for tendon pulling. Yes, this mechanical steampunk-esk ratchet is meant for yanking on the fleshy strings found in all of us.
The unique mechanism is necessary because of the requirement for bidirectional actuation for bio-mechanics research. Tendons are meant to be pulled and released to measure the movement of the fingers or toes. This is then compared with the distance pulled from the actuator. Hopefully, this method of actuation measurement may help doctors and surgeons treat people with impairments, though in this particular case the “patient” is a chicken’s foot.
So often, we see 3D printers used to create some nifty little tool for a tricky little job. Maybe it’s to lock cams together for a timing belt change, or to work as a jig for soldering some complex device. However, some hacks are even simpler than that. [maker_guy] realized that eating nuggets in the car could be easier than ever with a little printed adapter.
The print is simple. It’s a round caddy for the nugget sauces given out by Chick-fil-A restaurants. Why round? Because it lets the nugget sauce sit neatly in your car’s cupholder at an accessible height. Put the sauce tub in the adapter, peel it open, and you can dip to your heart’s content.
So simple, yet a game changer all the same.
No more delicately balancing Zesty Buffalo by the gearstick while you try and chow down. Nor will your seat covers be tainted with Honey Mustard!
“Not a hack!” you scream. “It’s frivolous nonsense!” To that I say, are you a nugget eater or not? I myself partake, and I can absolutely see the value in this. You see, us journalists work hard. We’re often stuck eating substandard food in our cars on the way from one thing to another, like so many others in busy professions. If a smart little 3D-printed adapter can make mealtime easier and save some mess, I’m calling that a win.
You should never be afraid to use your creativity to make tools to improve your life. Parts are on Thingiverse if you need to print your own. Mod it to suit McDonald’s product if you need. Heck, print in black and it’d look like a stock part of the car!
You don’t have to like this simple adapter, but you can’t deny its utility! Share your own nifty little adapter ideas in the comments.
You might recognize [Robert Dunn] from his YouTube channel Aging Wheels, where he hacks on all sorts of automotive delights. On his other channel, Under Dunn, [Robert] tends to focus on building things. In this case, his nine chickens grew a bit, and he needs a new coop for his twenty chickens, three turkeys, and two geese. The build, the video, and the outcome are all typical of [Robert Dunn]’s videos- that is to say fun, informative, and easy to follow along with.
Rather than building on to his existing coop that was designed for less than a dozen chickens, [Robert] decided to start from scratch. Using CAD to overcomplicate matters at every possible step, the build flies together with impressive speed- but never quite takes off until the very last moment.
The video highlights all the things we want to see: The CNC’ing, the fails (including one very large fall-flat-on-your-face moment), the recovery from the fails, routed butt joints, and screen door handles. It’s also got all of the overengineered goodness we’ve all come to love. You’ll also enjoy his solution to moving, then fixing, then finally installing the coop.
If you enjoyed this, and watching people fail, check out [Robert]’s Fail Of The Week that we featured a while back.
Last week we featured a story on the new rules regarding drone identification going into effect in the US. If you missed the article, the short story is that almost all unmanned aircraft will soon need to transmit their position, altitude, speed, and serial number, as well as the position of its operator, likely via WiFi or Bluetooth. The FAA’s rule change isn’t sitting well with Wing, the drone-based delivery subsidiary of megacorporation Alphabet. In their view, local broadcast of flight particulars would be an invasion of privacy, since observers snooping in on Remote ID traffic could, say, infer that a drone going between a pharmacy and a neighbor’s home might mean that someone is sick. They have a point, but how a Google company managed to cut through the thick clouds of irony to complain about privacy concerns and the rise of the surveillance state is mind boggling.
Speaking of regulatory burdens, it appears that getting an amateur radio license is no longer quite the deal that it once was. The Federal Communications Commission has adopted a $35 fee for new amateur radio licenses, license renewals, and changes to existing licenses, like vanity call signs. While $35 isn’t cheap, it’s not the end of the world, and it’s better than the $50 fee that the FCC was originally proposing. Still, it seems a bit steep for something that’s largely automated. In any case, it looks like we’re still good to go with our “$50 Ham” series.
Staying on the topic of amateur radio for a minute, it looks like there will be a new digital mode to explore soon. The change will come when version 2.4.0 of WSJT-X, the program that forms the heart of digital modes like WSPR and FT8, is released. The newcomer is called Q65, and it’s basically a follow-on to the current QRA64 weak-signal mode. Q65 is optimized for weak, rapidly fading signals in the VHF bands and higher, so it’s likely to prove popular with Earth-Moon-Earth fans and those who like to do things like bounce their signals off of meteor trails. We’d think Q65 should enable airliner-bounce too. We’ll be keen to give it a try whenever it comes out.
Look, we know it’s hard to get used to writing the correct year once a new one rolls around, and that time has taken on a relative feeling in these pandemic times. But we’re pretty sure it isn’t April yet, which is the most reasonable explanation for an ad purporting the unholy coupling of a gaming PC and mass-market fried foods. We strongly suspect this is just a marketing stunt between Cooler Master and Yum! Brands, but taken at face value, the KFConsole — it’s not a gaming console, it’s at best a pre-built gaming PC — is supposed to use excess heat to keep your DoorDashed order of KFC warm while you play. In a year full of incredibly stupid things, this one is clearly in the top five.
And finally, it looks like we can all breathe a sigh of relief that our airline pilots, or at least a subset of them, aren’t seeing things. There has been a steady stream of reports from pilots flying in and out of Los Angeles lately of a person in a jetpack buzzing around. Well, someone finally captured video of the daredevil, and even though it’s shaky and unclear — as are seemingly all videos of cryptids — it sure seems to be a human-sized biped flying around in a standing position. The video description says this was shot by a flight instructor at 3,000 feet (914 meters) near Palos Verdes with Catalina Island in the background. That’s about 20 miles (32 km) from the mainland, so whatever this person is flying has amazing range. And, the pilot has incredible faith in the equipment — that’s a long way to fall in something with the same glide ratio as a brick.
Like most of us, [Hunter] and his partner [Katyrose] have been in quarantine for the past few months. Unlike most of us, they spun a 3D printed chicken playground design hackathon out of their self-isolation. The idea is simple: to build a playground full of toys custom-tailored to appease each chicken’s distinctive taste. The execution, however, can be proven a little tricky given that chickens are very unpredictable.
For each of the four select chickens in their coop, the couple designed separate toys based on their perceived interests. One, showing a fondness for worms, inspired the construction of a tree adorned with rice noodles in place of the living article, and moss to top it off. For late-night entertainment, the tree is printed in glow-in-the-dark filament. The others were presented with a print-in-place rotating mirror disguised as a flower, and a pecking post covered in peanut butter and corn. As a finishing piece, the fourth toy is designed as a jungle gym post with a reward of bread at the top for the chicken who dares climb it. Since none of the chickens seemed interested in it, they were eventually hand-fed the bread.
With no other entries to their hackathon, [Hunter] declared themselves as the winners. The 3D files for their designs are available for their patrons to print, should they have their own chicken coops they want to adorn. While the hackathon might’ve been a success for them, their chickens in particular seemed unimpressed with their new toys, only going to show that the only difference between science and messing around is writing it down, or in this case, filming the process.

Meanwhile, check out the video about their findings after the break.
Ah, the joys of domestic animals. Often adorable, occasionally useful, they’re universally unable to care for themselves in the slightest. That’s part of the bargain though; we take over responsibility for their upkeep and they repay us with whatever it is they do best. Unless the animal in question is a cat, of course – they have their own terms and conditions.
Chickens, though, are very useful indeed. Give them food and water and they give you delicious, nutritious, high-quality protein. Feeding them every day can be a chore, though, unless you automate the task. This Twitch-enabled robotic chicken feeder may be overkill for that simple use case, but as [Sean Hodgins] tell it, there’s a method to all the hardware he threw at this build. That would include a custom-welded steel frame holding a solar panel and batteries, a huge LED matrix display, a Raspberry Pi and camera, and of course, food dispensers. Those are of the kind once used to dispense candy or gum for a coin or two in the grocery; retooled with 3D-printed parts, the dispensers now eject a small scoop of feed whenever someone watching a Twitch stream decides to donate to the farm that’s hosting the system. You can see the build below in detail, or just pop over to Sweet Farm to check out the live feed and gawk at some chickens.
It’s an impressive bit of work on [Sean]’s part for sure, and we did notice how he used his HCC rapid prototyping module to speed up development. Still, we’re not convinced there will be many donations at $10 a pop. Then again, dropping donations to the micropayment level may lead to overfed chickens, and that’s not a good thing.
