Outreach Technology Cart
The Knox Makers Outreach Technology Cart is still being developed and resources are still being acquired. The two primary purposes of the cart is to have a central cart at Knox Makers for beginners to jump directly into a variety of projects and to have a cart that can be loaned to area partners (full cart or specific resources). Currently, the cart focuses on electronics kits and components. Ideally, the cart will be outfitted with a variety of crafting and arts supplies, as well.
The consumables on the cart are donated and should be seen as very limited. The cart is mostly designed for temporary projects that can be disassembled back to their original states.
This page itself is a WIP as the cart is being developed and hopes to eventually include example projects. Essentially, for loaned purposes, this cart can serve as supplemental temporary resources for program directors, teachers, and other professionals working with children and adult learners.
If you have been directed to this page, take a look and see if you spot anything you would like to borrow or familiarize with in the below inventory list. Contact the Board if you would like to schedule a cart or resource borrow of if you have any in kind donations for the cart, requests for more resources, etc.
It is also possible to get a 3D printer, Pablo the polargraph drawing bot, and even our retired Guenther (animatronic monkey meteorologist) out to a program but it may take more effort and will require at least one KM volunteer to help out and these are generally more advanced and costly tools that we do not actually loan out. If you are interested in looking into a 3D printer or Pablo to show up to your event (Guenther almost never gets out anymore), hit up the Board. The worst that can happen is that we say no because we are involved in too many other projects at the time.
Summary of what's on the cart
MaKey MaKey
We have five of the newest generation MaKey MaKeys. These are simple USB devices that can be used to make simple connections using conductive items (bananas, human hands, conductive thread, quarters, etc.) to emulate a keyboard and mouse. This can make for a powerful and engaging interactive demo/exhibit or a hands on invention program for even young learners. No programming or electronics experience is required, but many projects can segue into greater STEM experiences as a foundational building block.
The MaKey MaKeys come with USB cables and alligator clips. These clips use a basic mechanical mechanism similar to that of a clothespin. If you clasp the clip between your thumb and finger and apply pressure, the clip will open and can grab onto items. Each set of clips is actually a wire with an alligator clip on both ends, so that you can clip one end to the MaKey MaKey and the other end to your item (conductive wristband, quarter, strawberry, etc.)
When a conductive item that is connected to a controlling pin on the MaKey MaKey touches ground or a wire connected to ground on the MaKey MaKey, this completes the circuit and sends a signal to the computer that corresponds to the controlling pin. For example, if you have a banana wired to the pin that says "space bar" on the MaKey MaKey, hold a wire that is connected to ground on the MaKey MaKey, and then touch your hand to the banana, the computer will type a space just as if you had typed it on the keyboard.
Particularly when combined with programs and webpages that make effective use of the keyboard (see scratch.mit.edu, most movie players, various online pianos, music software, etc), custom inventions can make interacting with technology both an educational and unique experience.
To supplement our MaKey MaKeys, we have a variety of resources on the cart.
First, we have male/male and female/female jumper wires. These are great because you can easily snap into the smaller pins on the back of the MaKey MaKey without much fuss. You can also "plug" the other end of a male jumper wire into some objects such as a banana. Additionally, there is room to work with to experiment with quick connects for advanced projects. These bundles of jumper wires are fairly inexpensive. If you would like to secure your own, let us know and maybe we can add you in to our next groupbuy from Adafruit.
We also have an assortment of LEDs. These are handy because one of the features of the MaKey MaKey is that there are also a couple of bonus pins on the backside that send out power whenever mouse or keyboard movements are triggered from the MaKey MaKey. Using an LED in this way with the above banana example, when you touch the banana, not only will it send a "space bar" signal to the computer, it will also light up an LED. There are a variety of LEDs to use on the cart, including slow and fast fading LEDs that cycle through the color wheel. We also have flat panel LEDs and sewable LEDs.
While we're on the subject of the 5v output power pins, the cart also has noisemaking piezo buzzers and motors of varying types. Some of these will work better than others, and some might not work at all. These are included for tinkering purposes at the moment until the cart is better organized, but if you need help identifying the best components for your project we can probably find someone to help you out.
Most of the "buttons" are going to be very nontraditional buttons, such as someone giving someone else a high five, or a banana, or a bucket of water. This is part of the fun of the MaKey MaKey. However, we also have plenty of different types of tactile buttons and switches that can be wired up to the MaKey MaKey. This can help to take, for instance, a cardboard project up to the next level with a nice little "cool" factor. A cardboard guitar with some actual buttons and switches that work? Can do.
Last, we have our traces. What I am calling our traces here are really just our wire leads connecting items and people back to the MaKey MaKey. This can easily get into our consumables portion, but for large projects we would ask that you first try to think of a different cheap but creative solution. Keep in mind that the MaKey MaKey is so sensitive that banana peels are effectively conductive enough. We have conductive thread and fiber, we have conductive paint and ink pens.. but can you think of cheap or free alternative instead?
Let us know if you need help ironing out the consumables or zeroing in on the details of your activity/program.
As a side note, you can also combine the MaKey MaKey with other kits on the cart such as the Circuit Scribe kits.
