The United States Department of Energy holds annual high-school-level science competitions all across the United States and her territories. Schools send teams of 4-5 people to compete against other schools in the state or region, and the winning schools are flown up to Washington, D.C. to compete in the national tournament. The question categories include biology, chemistry, physics, math, general science, earth and space, and meteorology.
In Puerto Rico, the team to be Continue Reading
(If you haven’t noticed by now, I use black unmarked project boxes to house my projects in. A lot.)
Every year the U.S. Department of Energy sponsors a regional science bowl in Puerto Rico. Nearly every private school on the island participates, with some teams showing more promise than others. What doesn’t change, though, is the fact that Notre Dame’s established science bowl team always seems to win first place year after year. When the date for the regional Science Bowl comes close every year, our coach usually just calls the four most promising science enthusiasts from grades 10-12 to take part the weekend before the actual event. Since none of us have time to practice, many points end up being lost because of buzzer misfires.
Here’s the lowdown: Two teams com Continue Reading
As part of last year’s Physics Honors course, the class was divided into teams of two to three people to design and build a coaster capable of safely running a golf ball and a matchbox car down its track. It needed to have at least one loop of a minimum height and needed to slow the car (or ball) down enough to safely stop at the end without using a solid wall.

Here’s another goodie that I finished a while ago.
Every year the seniors buy an expensive iPod-dock-equipped boom box for our school’s senior hangout spot. Either because of abuse, inclement weather (the bohío has no walls), or negligence, it usually ended up getting trashed two-thirds into the year. Once it was our turn to inherit the bohío, I decided to try a different approach to our sound system problem.
The bohío is like an ou Continue Reading
I’ve finally found it – the poster that defines my spare time!
My friend Alberto and I saw this plastered on the window of a brick-and-mortar hardware shop in New York last time we visited. Seems fitting, doesn’t it?
I’ve always had a secret admiration for stores like The Salvation Army and Goodwill. They take in clothes, electronics, furniture, etc. that people donate and sell them, sending a huge chunk of profits to the homeless and the needy.
The thing about these thrift stores that I love is that you can find amazing deals on some pretty retro tech. I got a really old computer for exactly $9.99. Take exhibit A):
Toshiba T6600C – a “portable computer.”
This computer was released in 19 Continue Reading
This box may look familiar; It’s the final version of this earlier post.
Back with the same vibraphone problem: there was no speed control.
This 20+ year-old Musser Century 75 vibe was wired using nothing but analog circuitry; no electronic controllers, integrated circuits, or MOSFETs. They even originally used a mercury switch! (to keep noise down when powering on)
I called up Musser Percussion an Continue Reading
