LSM303DLM Breakout

Sensors are cool, but the really cool ones come in tiny packages that require breakout boards to be easily usable. I often buy (populated) breakout boards from one of the many hobby electronics vendors out there, but they are often in the $20 to $60 range (like this LSM303 breakout board), which is rather prohibitive. […]

Reduce noise on Arduino 400 kHz I2C with external pull-up resistors

Yesterday I wrote about how sensitive the I2C bus was to noise induced by merely touching exposed leads with a finger.

Tricopter: Electronics

(Disclaimer: the photos are blurry because my cell phone camera can’t focus on anything closer than 3 feet.) This is the underside of my Seeeduino Mega protoshield that will hold most of my tricopter’s electronics together. I wired up my accelerometer (BMA180) and gyro (ITG-3200) a few days ago without too much trouble using their […]

Raiderbot X Meeting 7, 35 Days to Robot Ship

Meeting time: 15:00 to 19:00 Hours logged: 47.86 We attached our 2005 game arm to the kitbot. It works! It’s a pretty big arm even though it doesn’t quite reach 10 ft. I can’t wait to see our four-bar linkage arm finished. Ordering parts… We need another cRIO, but I can’t find cRIO-FRC. NI has […]

My first robot!

My first electronics project, for that matter. I am currently taking an electronics class at my high school, and as part of the course, we are required to order and build an electronics kit. Since the kits provided were, in my opinion, too easy for me, I decided to order my own parts and build […]
