Have you ever gotten caught up in the romanticized idea of the Wild West and pioneer days? But, now that you are so used to modern conveniences have you decided life back then wouldn’t have been romantic at all? It would have been really, really, hard… Never fear – we have a resource to teach you how to experience parts of pioneer life – while in the comfort of your own home (and using some modern tools and safety equipment)!
Make: Like the Pioneers will walk you through a (somewhat) typical day in the life of a pioneer. A pioneer (and you!) start the day building a fire – no matches or charcoal allowed! Learn to make and use a bow drill – using branches, string, and a knife (or an optional handsaw!) and you’ll never be without fire again! You can continue the morning routine by making bacon soap (yes, soap and not soup)! There are several other morning activities to learn and enjoy – including “kitchen table cider making,” (both fermented and non-fermented). Just think – you can move through the rest of your “pioneer-day” smelling like bacon and drinking cider! Would you like to spend your winter evenings next to the fire writing a book about your pioneer experiences? Then you just might like to spend your mornings learning to make paper and binding your own book!
How about spending the afternoon making furniture?! According to Gordon Thorburn (the author of Chapter 6, “Fool’s Stool”), “Almost anybody can make a 17th-century board stool. In those early, pioneering times, techniques and tools were fairly primitive and ambitions consequently modest, so today, faking the American colonial style requires a do-it-for-fun, cavalier attitude rather than serious precision.” The list of materials and tools needed include, among other things, “cow manure (preferred) or wood stain…” (You can see in the picture [right] your homemade furniture doesn’t have to be perfect!) Perhaps making a “Rok-Bak” chair (from a single sheet of plywood) is more your style… You can also learn to “lash.” Chapter 8 is an entire chapter of full-page, full-color photos showing, in detail, how to build a sturdy platform using only sticks and twine!
Your evening can be spent pickling grapes and beets – or, in preparation for Halloween and Thanksgiving, you can learn to brine and roast a turkey and roast pumpkin seeds! There is also a delicious-sounding recipe for garlic herb butter for rubbing into that tasty T-day turkey!
Once those daily chores are finished, it is time to relax! Many pioneers spent their few leisure time making tools which would make their work and lives easier. Chapter 12 has clear, step-by-step instructions for building a da Vinci Reciprocating Mechanism. Learn to make a table-top version of da Vinci’s mechanism for powering a sawmill with a water wheel!
If you want to go waaaay back – perhaps to prehistoric times – you can create your own oil lamp! Since there are cave drawings from as long ago as 15,000 to 30,000 years ago, experts postulate there must have been a way to light those caves in order for the “primitive Rembrandts” to create those drawings. Oil lamps have progressed over time (obviously!) and the final chapter details how to make your own “Oil Lamp from the Cave Dwellers of Lascaux.” (An interesting fact: This chapter was written by William Gurstelle. Since volume 4, every issue of Make magazine has had an article written by him. We have all the issues here at the library – up to volume 57 now – so come in and check out all the other articles he’s written!)
So, ready to try your hand at living like a pioneer? Or at least “making” like a pioneer? I think you’ll find Make: Like the Pioneers makes it much easier than it was “back in the day!”
Interested in learning more about drones? Ever thought about building your own? We have the resources you need!
The best place to start might be understanding what a drone is. Dictionary.com defines a drone as “an unmanned aircraft or ship that can navigate autonomously, without human control or beyond the line of sight.” “Unmanned” is the term usually applied to drones, however, the term “uncrewed” has long been used by NASA, is gender-neutral, and thus is the term I will use whenever possible.
In the book Make: Getting Started with Drones, authors Terry Kilby and Belinda Kilby differentiate between types of uncrewed aircraft. For instance, a Remotely Piloted Aircraft (RPA), refers to model aircraft flown by a pilot on the ground using a radio transmitter. A UAV (uncrewed aerial vehicle) is an aircraft which is flown remotely or controlled autonomously using computer software and GPS. Uncrewed aerial systems (UAS or sUAS for a small UAS) refers to all related processes involved with uncrewed aerial technology.
The University of Iowa UAS Advisory Group says, “A UAS consists of an uncrewed/unmanned aerial vehicle (UAV) and the components necessary to operate and control the UAV. UAS are often referred to as drones. According to the FAA, a UAS is the uncrewed/unmanned aircraft and all of the associated support equipment, control station, data links, telemetry, communications and navigation equipment, etc., necessary to operate the unmanned aircraft….”
Now that we have a basic understanding of what a drone is, what’s next in learning to build your own? Both Make: Getting Started with Drones and DIY Drones for the Evil Genius begin with a brief history of flight and some basic principles of aeronautics. Understanding basic principles and the 4 physical forces involved in flight – thrust, drag, weight and lift – will help you design and build your own drone!
Make: Getting Started with Drones recommends building a Little Dipper drone first. The Little Dipper design is open source and downloadable, or alternatively, a complete kit may be purchased. The authors walk you through building the Little Dipper with detailed, step-by-step instructions and include color photos and graphics. Issue 51 of Make : Technology on Your Time (Join the Drone [R]evolution) also has step-by-step instructions (with color photos) explaining how to build a Little Dipper.
Ian Cinnamon, author of DIY Drones for the Evil Genius, recommends purchasing the small (fits in the palm of your hand), inexpensive ($15 or $25 with a simple camera) Cheerson CX-10 to learn and practice flying a drone – before designing and building your own. Basic flight instructions are included (with graphics), AND there are instructions on how to learn to flip your drone! Ready to build your own, from-scratch, not-from-a-kit drone? Cinnamon takes you through the process from the beginning (deciding what your drone will be used for – racing? photography?) to attaching LED lights and a radio-controlled switch for night flying! (Check out this review & flight of the Cheerson CX-10 on youtube!)
Interested in using your drone for search and rescue (SAR)? Make : Technology on Your Time (issue 51) has a section on amateur drone pilots (that could be you!) and SAR volunteering. Information on how to volunteer, what gear you need, how to prep – and do’s and don’ts are all included. There is also information about Search With Aerial RC MultiRotor (SWARM), an organization where volunteer pilots can register to participate in SAR.
If you feel creative when designing your drone, you could have a Death Star….
Okay – you are now ready to fly your drone! What else do you need to know? Laws, rules, and regulations!
The Federal Aviation Administration (FAA) website is a wealth of information about getting started, where to fly, resources and FAQs. There is also information about registering regulations, including a link to register your drone online. For example, if your drone weighs between .55 pounds and 55 pounds (25o grams to 25 kg) you will need to register. There are both civil and criminal penalties if you meet the criteria and do not register.
In addition to federal laws, you will need to check the laws for the state in which you plan to fly. A quick state-by-state guide can be found here. This website is current (2017) and at this point in time, Iowa has no drone laws which extend beyond the federal laws.
There may also be rules and regulations on drone use in localized areas. The University of Iowa’s UAS Advisory Committee has implemented a policy on drone use. The new policy applies to faculty, staff, and students – and any UAS which are operated by others on campus. There is a campus-wide “no fly zone” without prior permission. Among other things, it addresses privacy concerns, insurance and liability. It does allow drone usage for research, education, marketing, facilities management, and data collection. Be sure to check out the UI policy if you want to fly your new drone on campus!
If you’d like to learn more about how drones are used in military, civil, and disaster relief, check our many resources. Domesticating Drones covers covers commercial uses (package delivery, movie production, agricultural applications, etc.), uses in emergencies, and regulations in the United States and around the world. There is even a chapter on starting a drone business. Civil and Commercial Unmanned Aircraft Systems discusses how drones may be used in forest and ecological ways (i.e. forest fires), law enforcement and public safety uses, research, journalism, and more.
Military Robots and Drones provides background and history of using drones in military actions. It also looks at problems and controversies surrounding their use – including a worldwide perspective. Killing By Remote Control: the Ethics of an Unmanned Military lays out pros and cons of using drones in warfare and explores the moral and ethical implications that follow that decision.
Build a drone this summer! Be creative and DIY your own design! We have the resources to help you be successful! Happy Flying!

Most of us have at least heard of compost, but we really may not know much about how it helps the soil, what should – and should not – go into compost and how to effectively use it once we have it!
So. What is compost? Put simply it is decayed – and decaying – organic matter which improves the soil structure and has other benefits for plants. Humus, on the other hand, is well-decomposed plant and animal matter that resembles dark coffee grounds. It is aromatic, lightweight, and spongy – allowing it to hold water. The terms ‘humus’ and ‘compost’ are sometimes used interchangeably.
Why is composting important? Compost does much to increase the health of the soil. It increases the number of microorganisms in the soil, which in turn boosts the number of bacteria, fungi, and other organisms which become food for predators. The soil microbes help protect your plants from pests and diseases. For detailed information on all the benefits composting provides check out How to Make and Use Compost : The Ultimate Guide.
Did you know there are different types of composting?
Heat (or thermophilic) composting uses the heat released by microorganisms as they break down organic matter. When the compost heats up sufficiently it will kill weed seeds and pathogens. Cool composting may take 6 to 12 months (or longer) to produce usable compost, but has the advantage of needing no maintenance. Even without turning and adding moisture the (cold-loving) microorganisms will continue to break down the refuse.
Then there is vermicompost – a compost pile where certain worm species are used to consume and convert the organic matter into useful organic fertilizer. Vermicomposting can even be done in a simple indoor, household worm bin (yes, really!). There is also sheet composting – simply spreading your organic matter on top of the soil in sheets, where it then decomposes right where you need it.
There are several ways to contain the compost. Building a box or fenced in area is a nice way – if you have the space.
You may purchase compost bins – including ones that are meant to be turned and rotated – to help keep the compost aerated. However, purchased bins can be expensive. Don’t despair! If you’d like to begin composting but don’t have much space or money, here’s an easy DIY for you! The video, below, shows an easy way to make a compost bin using a garbage can. It is recommended that you put your new compost bin on cement blocks to let the air circulate through the holes in the bottom. The gentleman presenting the video talks about a 50/50 ratio of brown to green. For more information about what that means check out the paragraph about what goes into a compost bin!
You may hear that there is a desired ratio of “browns and greens” when composting. But what does that mean? Better terminology would be “high nitrogen” (green) and “low nitrogen” (brown). The terms “brown” and “green” are helpful, however. Browns are plant material that are, well, brown. Fall leaves, wood products, straw… And greens are, well, green. Fresh grass clippings, freshly picked weeds, and most kitchen scraps (even if they aren’t green….). For more complete information about the C:N ratio (carbon to nitrogen) check out Compost, Vermicompost, and Compost Tea : Feeding the Soil on the Organic Farm.
There are things that should not go into a compost pile – don’t add meat scraps and bones – they attract rodents, and no one wants that! Surprisingly, it is recommended you don’t add citrus peels or onions! Onions and citrus are both acidic and can kill the worms and microorganisms on which your compost pile relies. You’ll also want to be wary of composting weeds – you don’t want to replant them when you use the compost! Lay them out in the sun (on a shed roof, a drying frame, etc.) and when they are brown, dry, and brittle – toss them in your compost bin!
There are so many things that can be composted – shredded paper bags, stale crackers and cereal, used paper plates (without a wax coating), wine corks and toothpicks, old cotton or wool clothing (cut into small pieces), newspapers …. For a lengthy list check out 100 Things You Can (and Should) Compost.
Okay. That’s a lot of info about composting. So, what do you DO with all the compost you’ve been diligently making?
Just as there are differing types of compost piles and bins, there are different types of gardening. There are conventionally dug gardens (gardens in which the soil is turned by fork, spade, rototiller…) and no-dig gardens (which are just that – gardens in which you do not turn the soil).
There are advantages to the no-dig garden – besides the fact it is less work! For one thing, you don’t disrupt the earthworm aeration tunnels, nor do you slice the worms in half! By digging your garden you increase the amount of oxygen in the soil which oxidizes more of the carbon which causes carbon dioxide to be released into the atmosphere.
In both types of gardens you can use compost as mulch and top dressing around growing plants. You can also use mulch on plants in containers – including indoor houseplants! If you are interested in learning how to make your own potting mixes check out How to Make and Use Compost : The Ultimate Guide. There are also instructions for compost specifically for cuttings and seeds.
Now, go out and start that compost pile! Before you know it you’ll have great compost and a beautiful, lush garden!

Want to put your engineering skills to work and have fun doing it? How about making your own Punkin Chunkin trebuchet or catapult?
Most of us know what a catapult is, but do you know what is different between a catapult and a trebuchet? A trebuchet uses a sling and has a counter-weight which, as it is dropped, forces the long arm up to pull the sling and the projectile along a slide at the base. The counter-weight uses the pull of gravity to provide the force necessary for the arm to swing upwards. The sling increases the length of the arm which increases the length of the throw. The catapult, on the other hand, uses a leaf spring mechanism to release the long arm. A rope is wrapped around a rotating drum and when the spring mechanism is released, so is the arm and the projectile. A catapult also has a cup at the end rather than the sling that a trebuchet has.
In 15 Dangerously Mad Projects for the Evil Genius, author Simon Monk says, “The trebuchet takes its energy from the weight that falls as the arm swings. The ‘potential’ energy is transferred to the arm and sling of the trebuchet and is released as kinetic energy in the tennis ball.” (or pumpkin…). He then explains that when you know the energy stored in the weight and how far the projectile can be thrown, then the energy going into the system and the energy released can be measured. Input energy can be calculated using the formula: E=mgh where ‘m’ is the mass of the weight, ‘g’ is the gravitational acceleration on Earth (9.8) and ‘h’ is the height. You can also calculate the amount of energy transferred to the tennis ball using the distance it traveled and its weight. E=1|2 mv2 where d=v2|g v2=dg. You can then calculate the efficiency of the catapult by dividing the energy transferred by the energy input. From this, you are then able to calculate the efficiency of your trebuchet! Ready to try to build your own? Monk also provides step-by-step, illustrated instructions, including a list of parts needed! The trebuchet project is rated as “Small,” (1/2 day to 1 day to complete) and the skill level receives 2 out of 4 stars (a small mount of soldering is required).
Rather make a catapult? Make : Technology on Your Time (volume 28, pages 84-94) will walk you through the process of building a gravity catapult. The larger the item you want to hurl through the air, the larger the catapult needs to be. Author William Gurstelle cautions that there are incredible stresses on the working parts of the catapult and if something should bend or break, it can be dangerous. He also emphasizes that a catapult is big. Once you build it, you need to have a place to store it (and to use it!) The gravity catapult shown in this issue of Make is small and light enough for one person to move. It also has wheels and (sort of) folds flat. Still want to try your hand? This includes an explanation of how it works, a list of materials and tools needed and complete building instructions accompanied by color illustrations!
The World Championship Punkin Chunkin contest has categories for both the trebuchet and the catapult. (Did you even know there is a World Championship Punkin Chunkin Contest?) It’s being held in Bridgeport, Delaware, this year. The goal is to encourage teams to use their science and engineering skills and also attract tourists. All the money raised goes to scholarships and community-based non-profits which support area youth. And in case you are wondering if Punkin Chunkin is a waste of good food, this is what the World Championship Punkin Chunkin Association (WCPCA) website says, “Majority of the pumpkins that are grown for competition are hybrids. Each year, we donate all the remaining edible pumpkins to farmers to feed to their animals. Shooting pumpkins has resulted in us being able to donate over 1 million dollars since 2000.”
If you don’t have the space to build a full-size catapult or trebuchet, how about making a smaller, desk-size version? Watch the video to learn to make a Mini Candy Launching Catapult!
