Hack Your Recipes

If there is one thing Hackaday readers have in common, they like to make things. Of course, we don’t all make the same things and that’s great. But, unsurprisingly, a lot of people who like to create things include the kitchen as their workspaces. Why not? We all have to eat and there’s something very nice about cooking a meal for your loved ones or even just yourself. Cooklang is a markdown-style language from [Brian Sunte] specifically for capturing recipes. It not only formats the recipe, but it provides an easy way for software to parse the key elements while still being human-readable. This allows you to manipulate recipes just like software, including using Git for version control, for example.

There was a time that cooking meant having big cookbooks, but now you are more likely to search the Internet. There’s only one problem. For some reason, nearly every recipe site follows the same format. Thousands of words about how much the cook’s family loves the dish, how they pick out only the most succulent tomatoes to ensure the dish will have a vibrant scarlet hue, and how much their poor granny would have loved the dish, if only she had survived the 1928 flood which is described in great detail. After 20 minutes you find out that you put the tomatoes in the blender, add a cup of water, and that’s it. Cooklang is a sort of antidote for that. You can easily write something that parses the recipe and generates, say, a shopping list or compares it to your household inventory and places an order for the remaining things from the local grocery delivery.

Camping For $25: Thrift Store Hacks To Keep Cozy

A hacker is somebody who’s always thinking creatively to solve problems, usually using what they have on hand. Sometimes that means using a 555 to build a CPU, and other times it means using a dead flashlight to start a fire. In the video below the break, [Kelly] shows us a series of hacks you can use while camping in the woods for a night to keep you warm, dry, and well fed!

[Kelly] started his camping trip not in the woods, but rather at a local thrift store. Instead of packing along hundreds of dollars in gear, his aim was to keep costs low. Very low. With some searching he was able to find a blanket, cooking utensils, rope, knife, tarp, and several other camp necessities for just $25.

A good campfire is a necessity of course, and [Kelly]’s full of great ways to start a fire even if all you have is a lighter with no butane or an old flashlight with dead batteries. The purpose of the video is to show how anyone can get their bush craft on even when all they have is a few dollars and a little know-how, which he generously shares. And after watching, we’re sure you’ll agree that he met his mark.

Will you raid the local second hand store before your next camping trip? After seeing this video, you just might! And while you’re there, make sure to grab the things you’ll need to make your own camping-friendly French press so you have some good coffee while you’re out camping in your… uh… Corolla?

Automated Mushroom Cultivation Yields Delicious Fried Goodies

[Kyle Gabriel] knows mushrooms, and his years of experience really shine through in his thorough documentation of an automated mushroom cultivation environment, created with off-the-shelf sensors and hardware as much as possible. The results speak for themselves, with some delicious fried oyster mushrooms to show for it!

Fried oyster mushrooms, grown from scratch.

The most influential conditions for mushroom cultivation are temperature, humidity, and CO2 concentration, and to automate handling the environmental conditions [Kyle] created Mycodo, an open-source system that leverages inexpensive hardware and parts while also having the ability to take regular photos to keep an eye on things.

Calling [Kyle]’s documentation “comprehensive” doesn’t do it justice, and he addresses everything from setting up a positive pressure air filtration system for a work area, to how to get usable cultures from foraged mushrooms, all the way through growth and harvesting. He even includes a delicious-looking recipe for fried mushrooms. It just doesn’t get more comprehensive than that.

We’ve seen [Kyle]’s earlier work before, and it’s fantastic to see the continued refinement. Check out a tour of the whole thing in the video embedded below (or skip to 16:11 if you want to make yourself hungry.)

Astronaut Food Is Light Years Beyond Tang And Freeze-Dried Ice Cream

When it comes down to it, we humans have two major concerns when venturing away from home for an extended period of time: what we’ll eat, and where we will sleep. Depending on the mode of travel, you might take some snacks along, or else rely on restaurants and/or the pantry of your possible hosts. Until the day we can reliably grow many types of food in space, or that Milliways, that five-star eatery at the end of the universe is operational, astronauts and other space-bound travelers will have to bring most of their food with them.

Cubes and Tubes

Space food has its roots in military rations, which in the United States were devised during the Revolutionary War. Both the variety and delivery methods of food have changed significantly since the beginning of the space program. While the menu may have at first been limited to tubes of nutrient-rich goo, bite-sized cubes and freeze-dried powdered beverages, the fare is more far-out these days. Astronauts on the ISS even enjoy tortillas, fresh fruits, and vegetables thanks to resupply missions, though they have to eat some of these types of foods quickly.

The average astronaut has also changed quite a bit, too. At first, they were all young and super-fit ex-military men, but nowadays they are more likely to be middle-aged science-y types and women. All three of these groups have different nutritional needs when faced with the rigors of living and working in space.

Taste The Television: TTTV

Associate Professor [Homei Miyashita] from Meiji University’s School of Science and Technology in Tokyo has developed a new technology for reproducing taste on a television or monitor, a system called Taste the TV (TTTV). The team of researchers used taste sensors to sample a variety of foods, and came up with a palette of 10 different aerosol flavors which can be combined in various ratios. The taste is generated in a staging area at the top of the screen onto a thin plastic film, which is then scrolled down into position.

Possible applications shown in the video below the break include cooking programs, restaurant menus, and wine tasting events. We’re not quite sure how popular this would be to consumers. Tele-tasting a cooking show with friends would be inconvenient, if not unsanitary. We’re also not aware that current video interface protocols such as HDMI or ATSC include any provisions for senses other than sight and sound. If you have access to scholarly journals, [Prof Miyashita] research paper on TTTV is available in the 34th Annual ACM Symposium on User Interface Software and Technology.

We’ve written about a couple of taste-generating projects before, see here and here.

several chocolate figurines of various sizes

Cast Your Own Holiday Chocolate Bunny, Or Rather Mouse

The art of forming and using a mold is, well, an art. The already tricky process would be made even harder by using a fickle material, like chocolate. This is exactly where [Alexandre Chappel] found himself as he tried to cast his own chocolate figurines.

The starting point was a 3D low-poly model of everyone’s favorite fictional electric mouse. He tweaked the model to add offsets so that after the model was vacuum formed, there would be something to clamp onto. [Alexandre] was left with four different pieces, and he vacuum-formed them with 1 mm PETG plastic. Electing for white chocolate to add coloring, he started heating the chocolate. Adding too much colorant resulted in a seized mess, so the process was a bit of trial and error. Finally, he poured in chocolate and spun it around to form an even layer of chocolate as a shell. The flashing lines were easy to trim with a utility knife.

The last thing to add was a little splash of color via airbrush and food-grade paint. The results are stunning, and even though the techniques are simple, the results came together nicely. The files are available on his website if you’re curious about making your own. If you’re curious about more clever casting techniques with chocolate, take a look at the creative use of diffraction grating to get iridescent chocolate.

Finally, A Piano BBQ Grill That You Can Drive Around The Workshop

It’s a truth universally acknowledged that sometimes a little music can add much to a nice afternoon picnic. It’s also well-known that meat cooked over hot coals should be turned regularly to allow for even cooking. This barbecue grille project from [Handy Geng] delivers on both counts.

The project uses a full 88 motors, activated by pressing keys on an electronic piano. The technique used is simple; rather than interface with the keyboard electronically or over MIDI, instead, a microswitch is installed under each individual key.

Thus, when the piano keys are pressed, the corresponding motors are switched on. Each motor turns a skewer loaded with meat, sitting above a box of hot coals. Thus, playing the piano turns the meat, allowing it to be cooked on all sides without burning.

As a further bonus, the entire piano barbecue grille is also motorized, allowing [Handy Geng] to do laps around his workshop while playing the piano and cooking up lunch. It’s a great way to cook up some grilled kebabs while simultaneously entertaining one’s guests.

We’ve seen some other fun grill hacks too – even robotic ones! Video after the break.
