  • News - Launching our products! | about 2 years ago

    PSmith, I am with Wayne. I want to design a board that uses and ATMega, or maybe the Arduino Mega, and either a 3 axis accelerometer and 3 axis gyro or the 9DOF Razor IMU breakout board with on board ATMega32, a barometric pressure gauge, GPS module, microSD card for data storage, USB plug to connect to a computer to download all the data, probably 3 or 4 high current FETs to fire pyros to release parachutes, etc, 4 servo ports to control fins, and maybe a pluing daughter card with a HAM radio license required telemetry system.

    But it sounds like the software to load on the 9DOF Razor to due true 3D inertial nav is not out there yet, if all they have is attitude and direction software. Also, we need a very high bandwidth between the rate gyros and the servos controlling the fins to help keep the rocket stable, or at least always pointing straight up until the motor quits and the speed falls off. With just the sensors you have for sale on this website, we can already make this super-duper Rocketduino in a very small package and run off of very little battery power. I have not yet started getting high power certified, by I am looking to go L3 with hybrid rockets and go for max altitude. As soon as I finish a hundred other projects, too :)

    I have enjoyed the upgrade to the TOL-00084, but while using it on my underwater robot, it fell off and hit tip first. It seems to have damaged the cable where the tips slide in. Where can I buy a replacement cable? It looks from the images above that the cable should be easy to replace.

  • Product DEV-00545 | about 4 years ago

    I would love to see one of these babies running a RepRap machine. The ability to store multiple build files on an SD card, download all the files over USB, then use a serial interface display to control which parts to print!

  • Product COM-00534 | about 4 years ago

    The Atmel recommends 12-22pF capacitors for their ATMega and ATtiny microcontrollers. So 22pF sounds like a good number.

No public wish lists :(
