LED Light-up Cards

I recently finished the holiday LED project where we created holiday cards containing small LED lights connected to circuits made of copper tape. First, you created image or pattern design using paper scraps on the front of your card. Then, you make a plan for the circuits. Your circuit design must be thoroughly thought through in order for the lights to work. The type of circuit you must build is called a ladder, because the LED wires look  like steps of a ladder, placed on the two main beams on either side of the circuit (made of copper tape).

See how the circuit looks like a ladder
After that you solder metal onto the breaks in the copper and use the melted metal to stick the LED wires onto the copper tape as well. And then, after adding a coin battery and ending the circuits, your card should be all set. I think I learned a lot about circuits and engineering in this project. If I could change anything about it though, I think I would have a more organized way of building the cards. During the project there were people running around and soldering for no purpose, or something crazy, and I think that if only we'd had a more intriguing and organized way of introducing and making the cards, the environment would be less chaotic and all students would be able to have a great learning experience. Other than that, I thought the project was great and Mr. Aringo did an excellent job teaching. Be sure to check out some cool LED patterns and circuits like the ones below!

Modern Day Abolitionist Nancy O'Malley

Alameda County District Attorney Nancy O’Malley was recently awarded the Modern Day Abolitionist Award from San Francisco Collaborative Against Human Trafficking (SFCAHT). During a recent online video interview, she told me about her involvement in human trafficking, her career, and her advice for young change-makers.
How did you first become interested in fighting human trafficking? When I was a young prosecutor in 1996, I was assigned a case that involved a 12-year old girl who had been sexually assaulted and raped by a 50-year-old man.  She started telling me her story and told me she had a 39-year-old boyfriend who took her out on the streets of Oakland and was selling her eight or 10 times in a night. When the police found her, the 50 year old man who had paid to have sex with her had raped her.  That’s when I realized she was talking about trafficking. We didn’t even have a law in California then. That’s how I first learned about it. I started getting a better understanding after t…

Criminal Justice Reform - "Locking Up Our Own"

When I came home from my arts-focused sleep away camp, I noticed a book on my mother's desk, "Locking Up Our Own" by James Forman Jr. My Dad saw me pick it up and told me the author would be speaking at a San Francisco bookshop the following week. I had read the book "Monster" by Walter Dean Myers in English class and visited the San Francisco Public Defenders office with the Youth Policy Camp, so I decided to go.

The last time I attended a bookstore for an author event was to see a picture book writer read to children. This was much different.

Forman, a well-respected Yale Law professor and former public defender, discussed policies from the '70s and '80s that were aimed at addressing rising crime rates, but resulted in the mass incarceration of blacks. Forman explained that many of the African-American officials taking office after the Civil Rights movement were the ones who lobbied for measures against drug-dealing and gun violence at the request of …

A Board Member's Perspective on San Francisco Public Schools

Rachel Norton is a former journalist who has served on the San Francisco Board of Education since 2009. She served on the SFUSD Community Advisory Committee for Special Education and is also an active member of Parents for Public Schools. I attended San Francisco public schools through 8th grade and was eager to hear her perspective.

What made you decide to first run for school board?

I have two daughters who attended SFUSD schools (both graduated from George Washington HS). I always knew I wanted to send my daughters to public schools and from the time they were in preschool I got involved with Parents for Public Schools and started paying attention to school board politics. 

My older daughter has autism, so from the time she entered Kindergarten I started volunteering with a group of other parents of students with disabilities, to help support parents through the IEP process and to help kids get the services they need. I became aware that so many kids were not getting what they needed,…
