Vote for us here!   So we took this:     And ended up with this:     With Paul looking a bit perplexed at controlling the arms with the BeagleBone Black, the tracking actually works!     The above video is the OpenCV code tracking the direction of the ball and predicting where it will go so that the motors controlling the arms can react.     The above video shows the arms moving in reaction to the location of the ball; it acknowledg ...
So after breaking a BeagleBone Black by putting 5v onto the breakout pin on the P8 side... we were supplied with a new one! (thanks!).   This meant that I could go back to coding for the scoring system. After working out the pinmux, from various confusing (inaccurate) sources and cross-referencing with the technical reference manual(s), for the mode and setting the pin for input,  I had something which, when the infra-red beam is broken, turns a green LED on. I've created a nice sprea ...
This week I intended on blogging about working and programming for the PRU in assembly and working with the GPIO.   Until I bricked the Beaglebone Black we were given.   Usually when you brick a device you can get it back up. Typically, it is the instructions/firmware on the flash chip that have corrupted or it's the operating system you're running on the board.   However, when you're wiring up the breakout pins (P8 / P9) and you accidently cross-wire the 5 volt line through a ...
We were not sure whom had time to work on the challenge, the majority of the members have full time jobs and other obligations, so evenings on weekdays and some weekends are often the best bet.   Paul Brook (pbrook) decided to head the challenge project, directing three other interested members; myself (Christopher Stanton / Stanto), Jon Stockill (nav) and Angus (ajtag).   We really needed a way to control the arms of the foosball table, and it was decided between PBrook and Nav that ...
Some have think tanks or mind maps, we just threw around ideas until something stuck over the course of a few days/weeks. Of course for a while we were introducing members of the space to what the BeagleBone Black actually was:   "Well, what can it do?"      "It's like a RasPi, mixed with a PiFace/Arduino, but faster, and done properly" "Okay, but what shall we do with it?"      "I dunno."   After everyone that turned up regularly enough was ...
