The finished thing. I really enjoyed making this; I enjoyed the physical process of making something that works as well as the process of figuring out what kind of stories you could tell with stuff like this. I want to do more. It's got some computer power in it. All I need to do now is work out how to put the Internet into it.

Arduino Mega with Adafruit GPS unit. The mega is nice because it has multiple uart/serial interfaces and that makes it easy to talk to computer/GPS/LCD.
Reloj gigante hecho con Arduino y Marmol.
Pegado de las planchas de marmol con silicona especial para piedra. Se endurece en pocos minutos y hay que ser muy rápido!
También se puede observar la linea fresada para encajar el cristal.

Our third Arduino 101 class at Tam Makers went really well. I taught this evening course with co-instructor Donald Day on Thursdays, from June 16 to 30, 2016, at the woodshop in Tam High School in Mill Valley.
We worked with an enthusiastic group of seven students, including adults with diverse backgrounds, as well as a couple high school students. Our partner Geo Monley worked both as a mentor and as a student during the hands-on sessions.
We started the class at 6pm, by giving students an overview of how circuits work. We then learned how to use a multimeter, how to solder electronics, and how to control rainbow-colored NeoPixel lights.
Students seemed to really enjoy this class and told us they learned a lot from it. Several expressed an interest in taking intermediate and advanced classes in the future. This is one of our first maker courses at Tam Makers, and we’re really happy that it is going so well; we look forward to teaching more classes in the fall.

Always wanted to write your own 8-bit video games? With a Gameduino and an Arduino you can do just that. The Gameduino is a game adapter for Arduino - built as a single shield that stacks on top of the Arduino and has plugs for a VGA monitor and stereo speakers.
Available from oomlout:
For the ArtHeist I need a way to control multiple AC devices (lights and stuff) from an Arduino. What's the safest, most reliable way to do that?
The Optek OSSRD0002A solid state relays are awesome and provide exactly that function. Take a cheap extension cord, cut it in two, wire up the Optek to one of the AC wires (wirenut the other two). Then hook any source of DC voltage from 4V to 32V to the logic side "+" & "-" inputs on the Optek to turn on the AC side.
To protect everything, I got a cheap $0.72 handy box and cover for electrical outlets and stuck everything in there.
Also, a red LED was added in parallel to the logic inputs to give a visual indication of it being switched on.
In short: Computer playing music, lights reacting / changing according to the song and frequencies.
This actually worked out OK, though I didn't get all the hardware + software bits and features that I had originally envisioned actually working.
I've assembled both shields a couple of weeks ago. The one with the breadboard has been borrowed to Alex for his "home automation / doorbell" project.
The other one has already been assembled, and I intend to use it in an autonomous robot project.
As soon as I finish my current project.
