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…

Interview with Rinku Sen, Writer and Activist

Rinku Sen is a writer and activist best known for her work with racial justice organization Race Forward and its award-winning news site Colorlines. Under Sen’s leadership, Race Forward had many successes, including a campaign to get media outlets to “Drop the I-Word” and stop referring to immigrants as “illegal.” (The Associated Press, USA Today, and the LA Times all changed their practice.)  I interviewed Rinku to better understand her particular career path.
What were you like as a teen? Did you know you would grow up to be a community organizer, writer, and activist?
When I was in my early teens I had no politics, so I definitely didn’t think I’d grow up to be an organizer. That is, politics didn’t interest me much, although history did.
I loved books. I started keeping a journal on loose-leaf 3-ring paper when I was 13, and I did want to be a writer. I read fast so I must have taken in thousands of romances and mysteries before I went to college. Some time during high school, one o…

Interview with John Bonifaz, Expert on Democracy and Voting Rights

John Bonifaz is a lawyer who uses his knowledge of the US Constitution to make sure people can vote and that their vote counts. He has co-founded two organizations: Free Speech for People, where he serves as president, and the National Voting Rights Institute. He believes it hurts our democracy to have wealthy individuals and corporations influencing and distorting elections. In 1999, he received a MacArthur Fellowship, also known as a “genius” grant, for his work on voting rights. (That’s the same award Lin Manuel Miranda received in 2015!)
You’ve founded two organizations focused on laws that relate to voting, the National Voting Rights Institute and Free Speech for People. Can you compare their areas of focus and approach?
I founded the National Voting Rights Institute in 1994 with the primary initial focus on challenging our nation’s campaign finance system as the newest barrier to our right to vote. Former Constitutional Law Professor Jamie Raskin – now Congressman Jamie Raskin of…
