The video explains how to build a basic circuit with the Arduino board, and how to use each of the basic components such as LEDs, switches, and resistors. See more videos on related topics. Massimo Banzi, the co-creator and CEO of Arduino, and seen in the videos, also has a book: Getting Started with Arduino.
Make is really is a wonderful way to find ideas. Some people have the imagination to come up with all sorts of projects to try, I don’t. But Make takes care of that for you and provides really interesting ideas for things to try out yourself.
A new brand of DIY self-sufficiency is spreading across The Netherlands. Skilled craftswomen, mechanics, seamstresses, and handypersons are banding together to resist disposable consumer culture. It is the rise of the Repair Cafe, a place where neighbors get together to extend the life of their material belongings. “Fixers” mend clothes, restore furniture, rehabilitate electrical appliances, and enjoy each other’s company while industriously toiling away. The first cafe was founded by Martine Postma in Amsterdam in October of 2009. Today, there are 20 fully operational Repair Cafes, and 50 more in the planning stages.
I really like these efforts. We throw away too much stuff that has plenty of useful life left. Also it is a great way to build community. And it is an interesting way to learn about products we use everyday (both by fixing them and having your items fixed). The throw away culture is something we should aim to change. By these actions and also by engineers designing products to be fixed instead of thrown away. I donated to a similar fixer collective in Brooklyn via Kickstarter.
Made by Hand by Mark Frauenfelder, the editor-in-chief of Make magazine. explores his adventures in the world of do-it-yourself.
Frauenfelder spent a year trying a variety of offbeat projects such as keeping chickens and bees, tricking out his espresso machine, whittling wooden spoons, making guitars out of cigar boxes, and doing citizen science with his daughters in the garage. His whole family found that DIY helped them take control of their lives, offering deeply satisfying alternatives for spending time together. Working with their hands and minds helped them feel more engaged with the world around them.
Frauenfelder also profiles fascinating “alpha makers” leading various DIY movements and grills them for their best tips and insights. He offers a unique perspective on how earning a few calluses can be far more rewarding than another trip to the mall.
Schematic diagrams are made up of two things: symbols that represent the components in the circuit, and lines that represent the connections between them.
If a line runs between components, it means that they are connected, period, and it tells you nothing else. The connection can be a wire, a copper trace, a plug-socket connection, a metal chassis, or anything else that electricity will run through without much resistance. Messy details like wire or cable specifications and routing, if they are important for a project, belong elsewhere in its documentation. The length of a line also has nothing to do with the connection’s actual distance in real life. Schematics are drawn (ideally) to be clear and simple, with components and connections arranged on the page to minimize clutter, not to represent how they might be placed on a circuit board.
The video and the article give you a good start on understanding schematics. There are 2 ways to show wires crossing in a schematic (the video shows one, the article shows both). Learning how to read a schematic gives you the ability to go many different directions with your home engineering efforts. Have fun.
Not a programmer? No problem! The EZ-Builder application allows non-programmers to easily build robots using advanced functions of the EZ-B Robot Controller. It is a Microsoft Windows application that gives you remote and scripting control of your custom robot design. Within the application, you add Controls that mimic your robot’s configuration. There are many controls for speakers, iRobot Roomba, HBridge, Servos, Cameras, Voice Recognition, Joysticks and more! There is even an easy scripting language so you may create short animations, interactions or initialization routines for your robot.
Using a Dremel, hot glue gun, screw drivers and various other tools, you can begin modifying the toy shell to fit your servos. For wheels or mobility, use continuous rotation modified servos. For arms and neck, use a standard servo. To allow your robot to see for object detection, use a Sharp IR Distance Sensor or a HC-SR04 Ultrasonic Ping Sensor.
The maker movement is excellent. As the program suggests it also serves to show many people enjoy engineering and making things work. Kids love to learn to accomplish things. Memorizing boring science details is not as interesting or a very useful way to create the kinds of innovative scientists and engineers that can aid our economy.
Calling all Inventors, Makers and Hackers. This is a fun idea for a hacker invitation. Teams decode the invitation embedded in hardware to reveal their password for an invitation to the creation event.
