OpenCV comes with a number of sample programs, in the samples\python directory. Below is a brief description of each. The more interesting demos are marked in bold. The list is by no means detailed and
When I first put the rover robot together, I used a camera mount that came with the camera. However this was inclined slightly upwards meaning it was difficult to see what was directly ahead. For
While buying something else, I spotted a small wireless relay module for £5 that looked useful, so I thought I’d buy one to investigate. It consists of a ESP-01s wireless microcontroller and a 5v relay.
All code in this example is included in the GitHub repository. When looking at adding a pan/tilt camera mount, I ran into a number of problems with the Raspberry Pi and serving PWM (see 9g Micro
When making a pan/tilt mount *link & article pending* for my PiRover robot, I ran into some issues with badly jittering servos. Following some suggestions on the excellent YouTube video from Gary Explains, did not
So far I have concentrated on driving my telescope and Zwo ASI camera, which is great for planetary and lunar imaging, but for widefield imaging with long exposures, a DSLR camera is a better tool,
Following on from previous posts about building a Raspberry Pi imaging server using Astroberry, the next stage was to add a remote focuser and dew heater control. Remote focusers are quite expensive, however small low
