Newborn humans are both amazingly resilient and frighteningly fragile creatures. A child born with a 40 full weeks of gestation has pretty good odds of surviving the neonatal period these days, and even if he or she comes along a few weeks early, things usually go smoothly. But those babies that can’t wait to get out and meet the world can run into trouble, and the earlier they’re born, the greater the intervention needed to save them.
We’ve all seen pictures of remarkably tiny babies in incubators, seemingly dwarfed by the gloved hands of an anxious parent who just wants that first magical touch of their baby’s skin. As common as such an intervention is now and as technologically advanced as neonatology is, care for premature infants as a medical discipline has a long and interesting history of technical and social hacks that’s worth looking at.

Millions of premature babies are born every year, and more than a few of these births occur hours away from any hospital with a NICU. [Manoj]’s entry for the Hackaday Prize is a simple, but very useful primitive incubator. Is it as good as the incubators you would find in a world-class hospital? No, but that’s not the point. This is an incubator for the rest of the world, where neonatal care is lacking.
You’re not going to get mechanical respiration or even oxygen into a device that is meant for the most far-flung areas on the planet, so this incubator focuses almost solely on monitoring. Packed inside a premie-sized sleeping bag is enough electronics to measure heart rate, blood oxygen, temperature and respiration. Also, there are a few resistive fabric elements to turn electricity into warmth.
Of course, anything you would find in any hospital or clinic would greatly outclass what this project has to offer. That’s really not the point, though; this incubator is cheap, can be deployed anywhere, and provides enough information to hopefully keep a preterm child alive. That’s good enough for us, and makes for a great entry into the Hackaday Prize.
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.

I was visiting San Francisco, scratching my head for something cool to cover for Hackaday. When it hit me: this is one of the leading cities in the world for starting new companies. It’s known for its software, but with Tesla, Type A Machines, Intel, Apple, and more within an hour’s drive of the city, there’s got to be a hardware scene as well. Silicon isn’t a software product after-all. But where do you find it, and how do you get a hardware start-up going in one of the most expensive cities in the world?
That’s where hardware accelerators or incubators, whichever name they prefer, come in. One-third hackerspace, two-thirds business crash course, they help you skip a lot of the growing pains associated with starting a capital intensive thing like a hardware business. I dropped in, and they kindly gave me a few minutes of their time. I wanted to find out what a hacker could do if they felt it was time to turn those skulls into dollars. What are the requirements. What is the cost? What help does the incubator offer to the burgeoning capitalist in a hacker?

FormLabs resins operate best between the comfortable temperature range of 18 – 28°C (64 – 82°F). For many of us experiencing the chillier weather these days, our garage workshops can easily drop below those temperatures and cause our prints to fail. Rather than hunker down for the freeze and wait for the world outside to defrost, [MarkStrohbehn] has discovered a budget heating technique that heats the print chamber from the inside instead.
This trick comes in two parts. First, to bring the temperature up, [Mark] installed an egg incubator inside the chamber using a powerful magnet attached to the fixture containing the lead screw. Next, to maintain the warm temperature, he’s taped together an insulating jacket composed of several layers of off-the-shelf mylar emergency blankets. Finally, he’s managed to slip the egg incubator power cable cleanly under the FormLabs lid without triggering the open-lid sensor. This hack is staggeringly simple but effective at reducing the odds of failed prints through the cold weather. Best of all, the modifications are far less invasive than other upgrades made to 3D printers, as it requires no modification of the Form1+. For those of us who haven’t seen the sun in a few months, rest assured that you can still churn out parts.
Ever wonder what kind of fecal content is in your drinking water? Do you also like yogurt? If so, this DIY Bacteria Incubator is just for you!
[Robin] is part of the BioDesign team for the Real-World project which is an interdisciplinary project featuring biology, electronics, and environmental sciences to bring together solutions for real world water problems. Since it’s a community oriented project they strive to keep it open-source and well-documented in order to share with everyone.
The DIY Incubator is a rather simple tool that can be used to help analyze water for fecal contamination, which is a problem in many third world countries. It consists of a styrofoam box, a light bulb and a home-brew Arduino which provides the PID control of the heat. For bacterial analysis, regular coliform bacteria live at 35C, while fecal coliform prefer about 44C — if incubated at these temperatures the bacteria will make itself known very quickly (within about 24 hours).
Oh and if you don’t want to find out how dirty your water is, you can also make yogurt instead. Check out a short demonstration of the incubator after the break.
