Window Installation and Exhibit with Mel Prest @ The Great Highway Gallery in SF

From July 16th - August 16th stop by the Outer Sunset’s gem of a space, the Great Highway Gallery, to see an installation by Mel Prest and I. We’ve been married artists for years, and somehow this our first collaboration! The title: Restructuring in Progress. We also both have several works for sale through the gallery. 25% of all sales during this period will be donated to the Bay Area chapter of Showing Up For Racial Justice (SURJ).

Sleepyboard Mini

Over the summer I designed a custom printed circuit board for a class I co-teach, in which students design and build a programmable lamp. I just got around to documenting the board. In the scope of PCBs, this is not a complex one but it's always nerve-racking to design and mass-produce a circuit board that many projects will depend on. One incorrect connection can void everything. So far the project has been a success! I call it "Sleepyboard Mini." http://www.extrasleepy.com/#/sleepyboardmini/

Sleepyboard mini is a custom PCB designed specifically to fit an Arduino pro mini, Adafruit USB micro-B breakout, an on/off switch and a few capacitors. There’s a small perforated breakaway prototyping area at the bottom of the board and a location for a single pushbutton at the top. All holes are connected horizontally in sets of 4 or 5, similar to a breadboard.

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, …

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)

This is the Arduino-based data collection system for the chicken coups.

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!
