NEW PIECE: SWEET LOAF

2019

CNC-cut walnut, 3D printed lens, Acrylic, Arduino, Addressable LEDs, Rechargeable battery

Sweet Loaf is a small rechargeable freestanding light source. The lamp can operate plugged to a wall or untethered for about 5 hours per recharge. A micro switch and usb charging port are embedded in the side of the acrylic. All machining on the wood and acrylic was done on the Bantam Tools Mill.

Dimensions: 5”w x 3”h x 4”d

Spring Semester Student Work Highlights

Here is a varied set of projects from the spring LWHS Device Invention (10-12 grade) and Design and Technology (9th grade) classes that, as I sorted through the semester’s documentation, caught my eye as extraordinarily innovative or generally well done.

This is a fly incubator, created for our genetics instructor, by a group of four 9th grade students. With custom-made incubation tube caddies, this container keeps the fly larvae (also known as maggots : 0) in an adjustable, temperature-regulated environment. This was created by Alex, Indigo, Max and Kaira.

This is an IOT project that uses RFID (radio frequency identification) to detect whether chickens have returned to the coup at night. The creator, Hannah (10th grade), noted that if the chickens do not make it back into the coup, they run the risk of being eaten at night. This system posts their status to a webpage and sends you a text at the end of the day letting you know which chickens “might be eaten”.

Another project by Hannah and her collaborator Emily visualizes the coup conditions for some neighborhood chickens. The two students built their own data collection system to record environmental data about the chicken coups, including temperature, volume and light level. They then used P5.js to visualize the data over a 24-hour period (above)

Above are a few of the 140+ lamps we built with the 9th-grade students in the team-taught Design and Technology course. Most students start the year with little to no experience in Design and Fabrication and are required to use wood, metal, acrylic and a programmed circuit in the making of the lamp.

Here is a pair of display-based IOT projects. The one above uses an API to display local movies and average audience review scores. The one below gives bus times and utilizes a funny ASCII representation of a Muni bus.

Finally, this 4ft-diameter target for the school’s physics department, created by a group of four 9th grade students (Marco, Lea, Adam and Mirabelle), is to be used for projectile experiments. When a marble is launched and hits the target, vibration sensors let you know which of the rings the marble lands on. Your score is displayed for five seconds on a digit display. It works amazingly well!

Some of the student made amplifiers from the Fall 2018 Analog and Digital class

These are of few of the portable bluetooth amplifiers from a class I teach at Lick-Wilmerding High School. Students spend a semester learning about the circuit parts as well as how the enclosure will affect the sound. Then, using skills from electronics to digital fabrication to metal and wood shop, they craft the circuit and enclosure from scratch.

Experimenting with Ml5.js

Ever since I completed the Machine Learning Literacy workshop back in February (at the School for Poetic Computation), I've been wanting to put together a project using Machine Learning. I finally finished something I call Land of LumpsLand of Lumps is an experimental comic strip that utilizes the word vector abilities of the machine learning library ml5.js (along with p5.js) to generate dialog for a second character based on the user’s input for the first. The output is pretty wacky...which I love. 

If you're like me and had never heard of word vectors before, here's a short explanation.

Land of Lumps is live!!! You should try it: http://extrasleepy.github.io/lumps/ 
A couple tips:
- Short phrases work better
- Avoid contractions

If you make anything you want to share, send it to me! Here are a few examples:

AMPLIFIER DESIGNS FROM FALL 2017 LWHS ANALOG AND DIGITAL CLASS

Here's a small selection of the 32 amplifier projects built by the Fall '17 Lick-Wilmerding Analog and Digital circuits classes. I've been facilitating this project each fall for a few years now and students continue to amaze me with innovative applications of design, material use, and tool application. All of the amplifiers have a class-D amplifier IC circuit at the heart, to which many students added extra features like analog potentiometers, bluetooth connectivity, and audio responsive lights.
