![]() Be sure to scale the 12V appropriately for your devices I/O levels. If you setup a rising edge interrupt and a timer, it is easy to measure the signal’s period. The RPM signal is a clean 12V pulse train who’s frequency is proportional to the engine speed. Here is a summary of the connections I made to the factory E36 sensors. Digital Dashboard: Factory Sensors and Pinouts and tagged hexapod, robot, ROS on Octoby admin. This entry was posted in Project Hexapod B.E.T.H. One of my goals is to learn more about ROS by creating nodes that support additional gait types. Step 3: Press the start button and you have control via the DS3. Step 2: Install hexapod-specific nodes using Kevin’s Github instructions Sudo apt-get install ros-kinetic-tf, and joystick, and state publisher Software and Updates, allow “restricted,” “universe,” and “multiverse.”.This is based off Kevin O’s hexapod ROS build which can be followed here: I’ll updated it with the bumps in the road as i hit them. This is a quick capture of the steps i used to install ROS on a Raspberry Pi 3 and use it to control my hexapod, B.E.T.H. This entry was posted in Digital Dashboard, Project M3 and tagged racecapture, racerender on Novemby admin. Their platform is growing fast and very receptive to community feedback so what’s not to like? I’ll make a another post with my latest data logging setup. It’s a highly customizable, open source solution, that includes solid hardware PLUS pretty decent software. This led me to eventually abandon my home-brew solution and look into the RaceCapture system from Autosport Labs. The problem is that all of the professional analysis software is locked to their proprietary data formats so there’s no way to use my data with their software. This requires much more advanced displaying and calculation of data to make it easier to pickup the clues and to develop as a driver. A huge part of data analysis is using it to learn where and why you were fast or slow on a given lap. I was able to make GPS plots and certain calculations in Excel, but besides screening for low oil pressures and high temps, it left a lot to be desired. I went from "f**k me, I just wasted $25 to this is pretty cool! - I am looking forward to playing with it some more".However, I sort of hit a wall once the data was collected. Last but not least, RaceRender technical support was outstanding in helping me out with issues. ![]() Of course, it I got an i-phone with 32GB storage in the first place, life would be easier - there isn't room on a 16GB phone for music, photos and 3 days HLT overlayed video! I just picked up the GoPoint BT1 OBDII bluetooth sensor that works with HLT for the next time, so I should get revs and throttle position next time out. I had to advance the HLT data file and video-audio file 2 seconds to allow enough "lag" to afford the adjustment. This allowed me to adjust the G-load data and align it with the footage. Remember to copy the lap time data with this, as this is the index RR2 uses to track the data. csv file into a new file and using that as the source for this data. I fixed this by cutting and pasting these columns from the. I had a problem with the lateral and lineal G data lagging in the data file. I also adjusted the LAP_INDEX field to adjust for the session, otherwise it would have started at lap 31/38, instead of 1/8.ģ) Syncing the data was straightforward, just remember to adjust the field you are syncing. RaceRender released an update that overcame this reading issue. This caused the data read to freeze at the endo of the first lap. Not sure what happened in the first place, but I got a usable work around to get the clip madeĢ) RR2 had an issue with the data recording time starting at 59:59:30.2 and rolling over to 00:00:00.00. mov file for video (it seemed better quality) and the. Once I converted the i-movie 'project' (as opposed to an event - the raw footage) to an MPEG-4 file, RR2 recognized the video and the audio. Once it had passed through i-movie, and the movie uploaded from the i-move "events" file, RaceRender recognized the video, but not the soundtrack. ![]() ![]() The source video is from my ContourHD camera and the data file from Harry's Lap Timer.ġ) RaceRender didn't recognize the. ![]()
