This is just a brief discussion of some of the choices that were made in the design of this project.First and foremost, everything was designed to be fabricated and assembled by me, "in house" so to speak. That meant that any chips had to be hand-solderable,...
Supposedly, I should be able to screw everything together, but since the CNC shop can't make that M3 threaded hole, i'll just glue everything together. No biggie. However:DO NOT STARE AT THE HEAT LAMP!!! this is from my own bloody experience. Just do...
Mike Jouppi12:55 PM Mike Jouppi12:55 PMOk, here is the board stack up Sven F12:55 PMOK, thank you very much. Your links are already helping me! Do you know any surface mountabe heatsinks manufacturers, too? So far I used some BGA-heat sinks and mounted...
Received boards back from OSH Park this week. Checked for mechanical mating to ensure measurements line up with the host board. Everything checks out okay, though the top mounting holes are not quite big enough for M3 screws. Thankfully nylon screws...
I want to have some clean, new and updated prints - so I had to basically redesign everything, except the gear parts. The gear that is stuck on the motor is bought and still on there. The motor will be fixed with screws and the standard screw size is...
All the stl files will be drop after the French Eurobot cup, the 1st June 2021. here you can see all the part involves, Everything has been design for an easy build and easy printed without support needed. Only 4 * M3 screw are needed for the frame ! 🔩It...

Hi!I've finished my day job and go back to design table. I've managed to finish the back case today, so the project design time it's almost done.I've added the lipo charger (powerboost 1000C), an on/off switch and the audio amplifier in the back case....
Just ordered some components from US suppliers, so they should get here fast:10 x 3Pin 10cm Servo Extension Lead Wire for Futaba RC Connector Cable LB10Pcs 2.54mm Pitch 0.1 1x15 15 Pin 15p Female Dupont Header Arduino Nano HeadersAnd then when those...
Just like the Warthog project, I use 3 mm black acrylic as a base for modules that holds LEDs, switches and buttons in place. a sandwich from one 2 mm and one 3 mm white translucent acrylic sheet is used on top of that to diffuse the LEDs and will be...
disclaimer: some of these posts are describing things that have already happened. im post documenting alot of things since i think this is a cool project that uses alot of different skills.Im a person who really likes to see/touch what im building so...
The firmware M3 is released today. We had some interesting time when for the first time a more then one interrupt is used and spent almost a month trying everything to make operation stable and predictable. Finally we found that Arduino's SPI transactions...
With the motors connected to Roboclaw, their direction and encoder in sync, and PID values tuned, Phoebe can be driven around via ROS /cmd_vel topic and report its movement via /odom. However, Phoebe has no awareness of its surroundings,...
I had read this tutorial, ordered my Arty board, and downloaded the Vivado Suite that the order gave me access to. Then everything set there for 3 months untouched. Today I came back to it, and this is my experience.Having done nothing other...
