This is a bicycle mount for a computer and a display unit of an ebike. It has 22mm and 32mm tubes to which computers can be mounted. The mount goes into the bar end of a steering wheel. This is paraticulary useful for recumbent bikes. The mount is designed for M5 nuts and bolts, but depending on the accuracy of your 3D printer you might need to use M4 bolts. You can download the 3D files over at GrabCAD.
It was time to improve the performance of this Raspberry C64 Pi computer by adding the official regulated fan to the case. I also added a USB audio adapter to improve the sound quality. With these two inexpensive upgrades, the Raspberry Pi performs much better and the audio quality is much improved.
Running A Raspberry Pi 4 in a C64 case with fully functional keyboard and USB hub.
I integrated a Raspberry Pi 4 into a Commodore C64 Maxi case. The Pi uses the integrated keyboard and the USB hub. An integrated power supply provides power to both, the Pi and the C64, which now run in parallel. The Raspberry Pi boots from an internal SSD drive, turning this machine into a full desktop computer that can also run Retro Pi for true retro gaming.
I started a new podcast series on Human-Robot Interaction. Have a look at the website to follow the latest episodes. I interview experts in the field and discuss technical, ethical and psychological issues around HRI.
A holonomic robot uses omni-directional wheels to drive and turn in any direction on the spot. Agilis is an example of an early LEGO holonomic robot. My model is much simpler and robust. Essential to all holonomic robots are the use of omni-directional wheel, such as the the ones from Rotacaster. I am using a compass sensor to allow the robot to be remote controlled on an absolute grid using Connexion’s Space Navigator. This 3D input devices can be mapped to the unique movements and rotations of a holonomic robot.
