I haven't got a kitten to chase my laser pointer, so I built this instead. Using an arduino board and a few LDRs, the reverse doesn't work yet, it needs some more calibration.
A quick demonstration showing the features and configuration options available on my Arduino-based GPS receiver.

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.

Mi placa Arduino, sirve para crear cosas que se mueven solas y formarán un ejercito que conquistará el mundo y sumirá la sociedad en 1000 años de oscuridad y toques elĂ©ctricos con baterĂas de 9V (?)
After the failure of an Arduino Nano I decided it would be good to be able to swap them easily and carry a spare.
You can see the top has a little bit of jitter, This appears to be a timing issue. But I can't seem to figure out why.
Code here, let me know if you make interesting modifications :D (See also the forum post)
UPDATE: I created a new thread, in English, for NTSC with updated code.
Note, you can run simple tests with the MaxM directly hooked up to Arduino like a regular BlinkM, but it's not very reliable: the poor Arduino chip just can't power those big LEDs on MaxM.
The solution is to either use a small breadboard and run power from the Arduino board's power supply to it (instead of powering it from an Arduino chip pin) or pop off the Blaster LED board temporarily.
Arduino for triggering a camera

Arduino clone with real-time clock, microSD socket and radio module. The layout is designed for easy assembly and maximum compatibility with the Arduino Uno, with additional functionality being compatible with the Arduino Mega2560. The optional LM61 temperature sensor is not fitted. As this particular board is intended to be powered by a boost regulator fitted to a shield the 3.3V and 5V regulators, and power LED, have not been fitted.
Version 2 features a number of improvements: there are footprints for SOIC and DIP package real-time clocks and a 5V regulator has been added. The PCB now supports the latest Arduino shield layout, with dedicated pins for I2C and IOREF signals, and 3.3V or 5V operation is possible via a jumper. An RFM12B radio module and microSD socket have been added, both are restricted to 3.3V operation. The microcontroller can be clocked from either an external crystal or ceramic oscillator. The analogue supply is smoothed with an inductor as recommended in the Atmel datasheet.

Space was limited in my room so I decided long ago to remove my bed and build a lofted setup.
I do a lot of tinkering so I built in a U shaped desk that extends more or less around the full perimeter of my room with lots of space to work on things. My desktop setup lies directly underneath my bed and on the opposite side I have a soldering/electronics station.
I recently underwent a few hardware upgrades for my desktop which include a liquid cooled 6 core, 64 gb RAM custom machine and 3x 27" Achieva Shimian Korean IPS displays. These are mounted to the wall with monitor arms and can be pulled closer to the edge of the table if needed. The setup works really well for my 3d modeling and coding work.
They are also backlit by a RGB LED strip powered by an Arduino R3 and Python based client on the desktop which changes color according to the color on the screens. I find that it helps a lot with eye strain and adds a great ambiance to the room.
