Electro-Optical devices sells kits and spare parts to build a real, far-ranged LIDAR ranger, such as: nanosecond timer, transmitter module (high voltage laser power supply included on-board), receiver module (APD photodiode, PIN photodiode), controller, laser diodes (power 10W - 75W).

The price of the cheapest kit ERC2-KIT is $ 429 , but you can get even cheaper if you buy just the modules and assemble it yourself.

The boards are really small and are thus ideally suited to fit an UAV plane which includes a rotating mirror system and a capable memory onboard.  

Maybe there are some restricting laws about the power of the laser? Anyone knows?

Quadrotor steering system concept

Immagine%20senza%20titolo.jpg?height=391&width=750Hello everybody, just wanted you to know that I just published a paper here https://sites.google.com/site/imager3d/quadrotor It is a brief description of a concept-proof steering system for Quadcopters, based on the transposition of the center of mass of the copter. I have not made tests, it is just a straight idea. Thanks to the readers! bye droners

Hydrogen fuel for Long endurance UAVs

They did it. AEROPAK is a UAV specific powering solution. It runs just on water (hydrogen fuel) and delivers lots and lots of electricity.


This product has unbeliavable charateristics compared to our primitive battery packs, allowing looong flight times. I discovered it today, and am waiting for a quote from Horizon Energy Systems. They also sell a complete hydrogen power ssolution for RC cars.

New horizons for us! Enjoy

Unveiling the robot

Here you are some photographs of my flying robot.

It's a chinese replica of the t rex 450 equipped with brushless motor and lipo battery.

As you can see, there's a CMUcam mounted in the front. It points the helicopter in the direction (yaw control) of a coloured object, and follows it when this ascends or descends, lowering and raising height.

The new arduPilot mega with IMU shield is mounted on the tail boom, near the body. Currently it works just as a stabilization unit with little code modifications. In the future, when I'll have some spare time, I'll adapt it as an autopilot with gps guide and indoor navigation techniques such as the Polly algorithm (CMUcam software) which recognizes wall edges.

The goal of this project is to demonstrate (or not!) that cheap electronics and models can lead to a "successful" and reliable robot, to use as a platform for sensors.

in particular, the major goals to achieve are:

-long flight time

-payload weight

-almost absolutely fail-safe hardware and software, reliability

-autonomous navigation

upgrades can be a controller such as the RoBoard, the roboRealm vision software and a camera

I'll post more as soon (long) as i have time to work

BEAM navigation


This is the circuit for a phototropic walking robot insect which follows light.
It's based on M.Tilden's work, BEAM robotics: it's about analog control circuits (microcores) that simulate neural and nervous networks present in the in the real insects' spinal cord; these react to external stimuli in a robust and very reliable way. Many other circuits have been drawn to do things like follow light, sense obstacles and reverse motors.
Of course this works just for walkers for the moment.

here comes my project: a BEAM autopilot!
It will be based on conversion of digital data coming from sensors, GPS to analog current levels, that will be inputted to control circuitries like the one above. The outputs will then be reconverted to digital for actuating servos and so on. I haven't still drawn nor calculated anything.

This is just a newborn concept, now I'd like to hear opinions of feasibility from experts in electronics I'm such a stinky newbie!

Thanks to everyone who will give me some thoughts!!

Zhichuan ZCC210N compass

Hey everybody, I'm attaching the code written by me for the Zhichuan zcc210N 2-axis magnetometer compass module. It's cheap, supports I2C interface and spits out data pretty good, including Direction (N-NE-E-SE, ecc) and angle (0-360°). Tested on Arduino pro mini. Frrrrresh.

NOTE I wasn't able to clearly understand how calibration is made. However the compass works fine even without calibration; google "zcc210n datasheet" for further info.

Note2: you have to input your local magnetic declination and deviation angles in the respective tabs for true north correction.

Bon apetit.

EM406: busted!

Ciao to everybody, just want you to know that today I finally made my EM406, ArduIMU and Ardupilot work together with a simple trick. From http://seniord.ece.iastate.edu/dec0803/manuals/EM-406%20Product_Guide1.pdf we see that the output baud rate of the infamous EM406 is 4800 bps. Adjusting the code for arduIMU, ardupilot to work at 4800 everything works very fast, ever without the "first time" GPS locking procedure. All right.
The only problem is that one might desire a higher than 4800 output rate. Argh, I am a very newbie to arduino and I am still searching for the solution.


So, with the help of Hopslink, I finally got it all working.

This made my arduIMU connect with the so-hatred EM406 module without using the NMEA protocol.

If you make arduPilot communicate with arduIMU @ 38400 bps you're really done. That's it.
